The required number of markers does Gerald has 56 markers.

Let's represent the number of markers that Gerald has with the variable "m", and the number of pens he has with the variable "p". We can set up two equations based on the information given:

m + p = 78 (equation 1)

(m + 11) + (p + 11) = 78 (equation 2)

In equation 2, we add 11 to both the number of markers and the number of pens, since Gerald has 11 more of each. We can simplify equation 2 by combining like terms:

m + p + 22 = 78

m + p = 56 (equation 3)

Now we have two equations with two variables. We can use either substitution or elimination to solve for one of the variables. Let's use substitution and solve for "m" in terms of "p" using equation 1:

m + p = 78

m = 78 - p

Now we can substitute this expression for "m" into equation 3:

m + p = 56

(78 - p) + p = 56

Simplifying the equation, we get:

78 - p + p = 56

78 = 56 + p

p = 22

Therefore, Gerald has 22 pens. To find the number of markers he has, we can substitute this value of "p" into equation 1:

m + 22 = 78

m = 56

So, Gerald has 56 markers.

Answer:

b

Step-by-step explanation:

given a quadratic equation in standard form

ax² + bx + c = 0 (a ≠ 0 )

the discriminant b² - 4ac informs us about the nature of the roots

• If b² - 4ac > 0 then roots are real and irrational

• If b² - 4ac > 0 abd a perfect square then roots are real and rational

• If b² - 4ac = 0 then roots are real and equal

• If b² - 4ac < 0 the roots are complex

4x² + 6x - 7 = 0 ← is in standard form

with a = 4, b = 6, c = - 7 , then

b² - 4ac = 6² - (4 × 4 × - 7) = 36 - (- 112) = 36 + 112 = 148

since b² - 4ac > 0 then roots are real and irrational

The probability of flipping heads and rolling a three is zero. These are two independent events, and the probability of each event occurring is 1/2 for flipping heads and 1/6 for rolling a three. Therefore, the probability is 1/12, which can be written as a fraction.

To calculate the probability of two independent events occurring simultaneously, we multiply the probabilities of each event. In this case, flipping heads and rolling a three are two independent events. The probability of flipping heads is 1/2 because there are two possible outcomes (heads or tails), and assuming a fair coin, each outcome has an equal chance of occurring. Similarly, the probability of rolling a three on a fair six-sided die is 1/6 because there are six possible outcomes (numbers 1 to 6), and each outcome has an equal chance of occurring.

When we want to find the probability of both events happening, we multiply the individual probabilities. In this case, (1/2) * (1/6) = 1/12. This means that out of all the possible outcomes of flipping a coin and rolling a die, only one out of twelve outcomes satisfies the condition of getting heads and rolling a three simultaneously.

Therefore, the probability of flipping heads and rolling a three is 1/12.

The approximate net pay of Juanita is $500. Therefore, option B is the correct answer.

Given that, Juanita has a part-time job that pays $12/hour and works about 50 hours every month.

Net pay means take-home pay or the amount employees earn after all payroll deductions are subtracted from their gross pay.

Now, total money earned in a month

= 12 × 50 = 600

Now

6.2% of 600 = $37.2

= 600 - 37.2 = $562.8

1.45% of 562.8 = $8.1606

= 562.8 - 8.1606 = $554.6394

10% of 554.6394 = $55.46394

= 554.6394 - 55.46394 = $499.17546

Total deductions = $499.17546

So, net pay = grass pay - deductions

= 600 - 105.9

= $499.17546

The approximate net pay of Juanita is $500. Therefore, option B is the correct answer.

The surface area formula for a triangular prism is 2 * (height x base / 2) + length x width1 + length x width2 + length x base, as seen in the figure below:

A triangular prism is a stack of triangles, so the usualy triangle solving rules apply when calculating the area of the bases.

Answer:

510 square meters

Step-by-step explanation:

You can divide this figure into a number of 2D shapes which you know how to find the area of.

The two triangular sides of the prism each have areas 12*5/2=30 square meters. The area of the rectangle formed by the smaller leg has area 5*15=75 square meters. The area of the rectangle formed by the larger leg has area 12*15=180 square meters. The area of the rectangle formed by the hypotenuse has area 13*15=195 square meters. Adding all of this together, you get:

30+30+75+180+195=510 square meters. Hope this helps!

Answer:

the answer is (a) 28.

Step-by-step explanation:

The given situation can be represented by a linear equation of the form:

Cost = mx + b

where "m" is the slope (the rate of change of cost with respect to time), "x" is the number of hours of the tour, and "b" is the y-intercept (the cost when x = 0).

In this case, the y-intercept is $60, which represents the one-time fee. The cost increases by $28 per hour, so the slope is:

m = $28/hour

Therefore, the answer is (a) 28.

The coffee distributor should mix 56 pounds of Mexican Shade Grown coffee blend and 34 pounds of Terraza coffee blend to create a 90-pound coffee blend that can sell for $10.99 per pound.

Let's assume x represents the number of pounds of Mexican Shade Grown coffee blend that need to be mixed, and y represents the number of pounds of Terraza coffee blend.

From the given information, we can set up the following equations:

1) The total weight of the coffee blend: x + y = 90

2) The total cost of the coffee blend: (9.10x) + (14.10y) = 10.99 * 90

Simplifying equation 2:

9.10x + 14.10y = 989.10

Now, we can solve this system of equations to find the values of x and y.

Multiplying equation 1 by 9.10 to eliminate decimals, we get:

9.10x + 9.10y = 819

Subtracting this equation from equation 2:

(9.10x + 14.10y) - (9.10x + 9.10y) = 989.10 - 819

Simplifying:

14.10y - 9.10y = 170.10

5y = 170.10

y = 170.10 / 5

y = 34

Now, substitute the value of y into equation 1 to solve for x:

x + 34 = 90

x = 90 - 34

x = 56

Therefore, the coffee distributor should mix 56 pounds of Mexican Shade Grown coffee blend and 34 pounds of Terraza coffee blend to create a 90-pound coffee blend that can sell for $10.99 per pound.

To meet her daily goal, Ling need to pedal approximately 1,008 revolutions each day.

To find the number of revolutions Ling will need to pedal each day to meet her daily goal, we need to first find the circumference of her unicycle tire.

The circumference of a circle is given by the formula C = 2πr, where r is the radius of the circle. Since the diameter of Ling's unicycle tire is 20 inches, the radius is 10 inches. Therefore, the circumference of her unicycle tire:

C = 2π(10) = 20π inches.

Next, we need to convert Ling's daily goal of one mile, or 5280 feet, to inches. There are 12 inches in a foot, so 5280 feet is equal to 5280 * 12 = 63360 inches.

Finally, we can find the number of revolutions Ling will need to pedal each day by dividing her daily goal in inches by the circumference of her unicycle tire in inches:

Number of revolutions = 63360 inches / 20π inches = 20,160π / 20π = 1,008

Therefore, Ling will need to pedal approximately 1,008 revolutions each day to meet her daily goal.

It takes a train going 50 mph approximately 11/2 miles to stop safely.

The distance a train takes to come to a stop can be determined by several factors, including the speed of the train, the weight of the train, the condition of the brakes and the track, and the reaction time of the engineer.

In general, a train going 50 mph will take about 1 1/2 miles or 8,000 feet to stop safely. This is because a train moving at 50 mph is traveling at about 75 feet per second, and it takes a significant distance to slow down a heavy object moving at such a high speed. It's important to note that this is an estimation, and the actual stopping distance may vary depending on the specific conditions.

Add the measurements to the drawing. Angle JEF and angle JFE both measure x degrees, while angle JED measures 180 - x degrees.

To find the measure of the base angles JEF and JFE in a trapezoid, we need to consider the fact that the opposite angles of a trapezoid are supplementary, meaning they add up to 180 degrees.

Since the trapezoid has two pairs of opposite angles, we can apply this property to solve for the base angles. Let's assume angle JEF measures x degrees. Since angle JEF is opposite to angle JFE, the measure of angle JFE is also x degrees.

Now, let's consider the other pair of opposite angles. Since the sum of the measures of the opposite angles is 180 degrees, the measure of angle JEF plus the measure of angle JED equals 180 degrees. Since angle JEF measures x degrees, we can set up the equation: x + JED = 180.

The given question is half of part , the full answer for the question is below.

To find the measure of JED, we subtract x from both sides: JED = 180 - x. Finally, we can add the measurements to the drawing. Angle JEF and angle JFE both measure x degrees, while angle JED measures 180 - x degrees.

The angle of elevation of the hill to the nearest degree is 44°.

The angle of elevation is the angle formed between the horizontal and an observer's line of sight to an object that is located above the observer. In this case, Tina is standing at the bottom of the hill and looking up at Matt who is standing on the hill. When Tina's line of sight is perpendicular to her body, she is looking at Matt's shoes.

This means that the line of sight forms a right angle with the ground.

To find the angle of elevation, we can use trigonometry. We know that the opposite side is the height of the hill (from Matt's shoes to the top of the hill), which is not given in the problem. However, we can use the Pythagorean theorem to find it.

Let h be the height of the hill. Then,

h^2 = (14.5)^2 - (5)^2
h^2 = 198.25
h ≈ 14.1 feet

Now, we can use the tangent function to find the angle of elevation.

tan θ = opposite/adjacent = h/14.5
tan θ = 14.1/14.5
θ ≈ 44.2°

Therefore, the angle of elevation of the hill to the nearest degree is 44°. This means that the hill slopes upward at an angle of 44° from the ground, as viewed from Tina's position at the bottom.

Answer: moderate, C, B

Step-by-step explanation:

A)  A shows a moderate negative correlation.  It is moderate because the scattered points are sort of close to the line so it has moderate/medium correlation.  It is also negative because it has a negative slope

B) C shows the strongest correlation because the points around the line are tight and close.

C)  B should not have been drawn.  The  correlation is very weak.  You do know where the line should be because the points are all over the place.

A. No, because the alternatives are not quantifiable.

B. No, because the alternatives are quantifiable.

C. Yes, because the alternatives are quantifiable.

D. Yes, because the alternatives are not quantifiable.

In decision-making, the quantifiability of alternatives refers to the ability to assign numerical values or measures to different options. Option A states that the alternatives are not quantifiable, suggesting that they cannot be measured or compared using numerical values. On the other hand, option B asserts that the alternatives are quantifiable, indicating that they can be measured and compared using quantifiable criteria.

To determine the correct answer for each scenario, we need to consider the nature of the decision and whether the alternatives involved can be assigned numerical values or measures. For example, when deciding on the paint color for the factory floor or extending cafeteria business hours, the alternatives may involve both quantifiable costs and benefits, making option B the appropriate choice.

However, in scenarios such as hiring a new engineer or changing the work shift, the qualities, qualifications, or effects involved may not be easily quantifiable, leading us to choose options D and C, respectively.

Ultimately, the correct answer depends on the specific context and the extent to which the alternatives can be measured or compared using quantifiable criteria.
