Answer: The dimensions of the gray rectangle is 1m by 12m.

Step-by-step explanation:

If you find out the perimeter of the pink square, you can use the same concept to find the dimensions of the gray rectangle:

Perimeter=(L+W)*2

Substitute it: (6+7)*2=13*2=26

Now basically do trial and error: 1*12=12m

Check it: (1+12)*2=13*2=26

In conclusion, the dimensions of the gray rectangle is 1m and 12m.

Of the students who have coffee with breakfast, the probability that two students, randomly chosen, have coffee with breakfast is 16.5%.

Probability refers to the chance or likelihood that a scheduled event or outcome occurs amid many possible results.

Probability produces a fractional value unless the expected event is 100% sure to occur or 100% uncertain.

The percentage of students at the community college who have coffee with breakfast = 66%

Sample size = 2 students randomly chosen

The probability that 1 student drinks coffee with breakfast = 1/2 = 50%

The probability for both students = 25% (50% x 50%)

Out of 66% of the students who have coffee with breakfast, the probability that two students, chosen randomly, have coffee with breakfast = 16.5% (66% x 25%).

Thus, the chance that the two randomly chosen students drink coffee with breakfast is 16.5%.

The required value of unknown number a would be 2000.

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

The relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.

WE need to determine 55% of what number is 1100.

Let the unknown number is a. then we get;

55% of a = 1100

55/100 of a = 1100

55/100 x a = 1100

Cross mulitiplication, we get;

55a = 1100 x 100

55a = 110000

Divide by 55, we have;

a = 110000/ 55

a = 10000/ 5

a = 2000

Therefore, the required value of unknown number a would be 2000.

Answer:

A.

Step-by-step explanation:

The vertical line test is a way of finding out if a relation is a function.

Graph the relation.

Then imagine a vertical line moving from left to right over the graph of the relation.

If the vertical line intersects at most one point of the graph in any position you place the vertical line, then the relation is a function.

This function passes the vertical test since it never intersects more than one point on the vertical line at a time.

Answer: A.

The amount cheaper is the car washes Malcolm orders than the car washes Martha's order is $13.

The correct answer choice is option B.

Malcolm's gift card = $50.

Cost Malcolm's car wash per visit = $7

Martha's gift card = $180

Cost Martha's car wash per visit = Difference between gift card balance of first and second visit

= $180 - $160

= $20

How cheap is the car washes Malcolm orders than the car washes Martha's order = $20 - $7

= $13

Therefore, Malcolm's car wash is cheaper than Martha's car wash by $13

Step-by-step explanation:

5.00-.30= 4.70

4.70/.70=6.71

Shirley can buy 6 doughnuts if she wants them all in one carryout box.

To determine the number of doughnuts Shirley can buy, we need to understand the concept of word problems.

What is Word Problems?

Word Problems in Mathematics involves the use of mathematical concepts and understanding in solving real-life cases.

From the parameters given:

Supposed Shirley has $5.00 to spend.

But, we are told he wants all of it in one carryout box. So, if he first buys 1 doughnut with its carryout box, she has spent $1, leaving her with $4.

Now, we need to divide the remaining $4 with the charges of doughnuts;

i.e.

= $4/$0.7

= 5 doughnuts with a remaining amount of $0.5

Now, the total amount of doughnuts bought is

= (1 + 5) doughnuts

Answer:

99.85

Step-by-step explanation:

$99.85\text{ %}$

Notice that 52 inches is three standard deviations less than the mean. Based on the Empirical Rule, 99.7% of the yearly snowfalls are within three standard deviations of the mean. Since the normal distribution is symmetric, this implies that 0.15% of the yearly snowfalls are less than three standard deviations below the mean. Alternatively, 99.85% of the yearly snowfalls are greater than three standard deviations below the mean.

Answer: The function rule is f(x) = 5(10)^x. Using this rule, we can find f(0) by substituting x with 0: f(0) = 5(10)^0 = 5 * 1 = 5. So f(0) = 5.

Here are the steps to find f(0) using the function rule f(x) = 5(10)^x:

1. Substitute x with 0 in the function rule: f(0) = 5(10)^0

2. Any non-zero number raised to the power of 0 is equal to 1: f(0) = 5 * 1

3. Multiply 5 by 1: f(0) = 5

4. So f(0) = 5.

Answer:

f(0) = 5

Step-by-step explanation:

The given function is:

\(f(x)=5(10)^x\)

To find f(0), substitute x = 0 into the given function:

\(f(0)=5(10)^0\)

According to the zero exponent property, any non-zero number raised to the power of zero is equal to 1. Therefore, 10⁰ = 1:

\(f(0)=5 \cdot 1\)

According to the multiplicative identity property, when any number is multiplied by 1, the result is equal to the original number. Therefore:

\(f(0)=5\)

The initial speed of the particle is 48 feet per second.

The particle will be at rest at t = 4 s and t = 2 s, respectively.

The position of the particle at t = 12 seconds is 1440 feet.

The total distance travelled by the particle is 1456 feet.

Kinematics is a branch of mechanical physical that studies motion of particles without considering its causes. Herein we must look for the key features of the motion of the particle by analyzing and interpreting a cubic equation. The function velocity of the particle is the first derivative of the function position:

v(t) = 6 · t² - 36 · t + 48

Then,

v(0) = 48

The initial speed of the particle is 48 feet per second.

The times when the particle is at rest is found by using v(t) = 0 and solving for t:

6 · t² - 36 · t + 48 = 0

6 · (t² - 6 · t + 8) = 0

6 · (t - 4) · (t - 2) = 0

The particle will be at rest at t = 4 s and t = 2 s, respectively.

And the position of the particle at t = 12 seconds is:

s(12) = 2 · 12³ - 18 · 12² + 48 · 12

s(12) = 1440

The position of the particle at t = 12 seconds is 1440 feet.

The function increases in both t ∈ (0, 2) and t ∈ (4, + ∞) and decreases in  t ∈ (2, 4), then the total distance travelled by the particle is:

s = |f(2) - f(0)| + |f(4) - f(2)| + |f(12) - f(4)|

s = |40 - 0| + |32 - 40| + |1440 - 32|

s = 40 + 8 + 1408

s = 1456 feet

The total distance travelled by the particle is 1456 feet.

If the anticipated claim outcome actually occurs, it will either be possible to contact the variable again or both important processes will undoubtedly miss the statement.

Here,

We must convert cups to gallons because daisy cream is sold in bulks of cups. Since a gallon of Daisy cream comprises 16 cups, one quantity of Daisy cream contains:

=> 16 cups per bulk = 1 gallon 16 cups per bulk = 1 gallon

Moscow cream is offered in bulk quantities of 4 1/2 gallons, which is one gallon.

Thus, we must convert pints to gallons. A gallon of Marble cream comprises eight pints, hence one quantity of Marble cream contains:

=> 40 pints in a bulk equal 1 gallon, 8 pints, or 5 gallons.

As a result, we can see that Marble cream, with 5 gallons per bulk, has the most cream.

If the graph of \(f(x) = 4e^{0.1x}\) is blue, then the graph of \(f(x) = 4(1 + \frac{0.1}{0.5} )e^{0.5x}\) is green.

In Mathematics and Geometry, an exponential function can be modeled by using this mathematical equation:

\(f(x)=a(b)^x\)

Where:

Assuming x = 10, the output value of \(f(x) = 4e^{0.1x}\) is given by;

\(f(x) = 4e^{0.1x}\\\\f(10) = 4e^{0.1\times 10}\)

f(10) = 10.872

\(f(x) = 4(1 + \frac{0.1}{0.5} )e^{0.5x}\\\\f(10) = 4(1 + \frac{0.1}{0.5} )e^{0.5 \times 10}\)

f(10) = 9.9533

Therefore, the green graph most likely represents \(f(x) = 4(1 + \frac{0.1}{0.5} )e^{0.5x}\) .
