Answer:

Given the 2 values, height and the base, of these 2 triangles, we can assume that they are similar (meaning they share the same angles) as we have no other information to determine the height of the tree.

Therefore, if these triangles are similar, their corresponding sides are proportional. In other words, PZ/RT = QZ/ST or RT/PZ=ST/QZ

Hence, if we find the ratio of this, we can use it to find the side h

QZ/ST=PZ/RT

48/12=PZ/4

PZ/4=48/12

(PZ/4)3=48/12

PZ(3)/12=48/12

48/3=16

16=PZ.

Step-by-step explanation:

There's a simple and effective "visual" way to solve mixture problems that makes short work of this.

In the attached, the concentrations of the contributors are listed on the left. It can work well to put the largest contributor on top (though that is not strictly necessary). The target concentration is put in the middle between them, and the differences along the diagonals are computed.

The diagonal differences are reduced to lowest terms as a ratio in the right-hand column. These numbers can be compared to the problem statement to see how they relate.

In this case, the total is 4 L of juice, and the total of the ratio units is 4. Then the ratio units are the number of liters of the corresponding contributor:

"the difference between five more than the larger number and twice the smaller number' can be written as the expression 31 -3x.

Mathematical expressions consist of at least two numbers or variables, at least one arithmetic operation, and a statement. It's possible to multiply, divide, add, or subtract with this mathematical operation.

Given, the sum of two numbers is twenty-six the difference between five is more than the larger number and twice the smaller number' into a variable expression.

Since x represents the smaller of the two numbers,

Thus the larger number will be 26 - x

The expression asked above will be:

=> 5 + larger number - 2 * smaller number

=> 5 + 26 - x - 2 * x

=> 31 -3x

therefore,  "the difference between five more than the larger number and twice the smaller number' can be written as the expression 31 -3x.

The volume of a paraboloid is therefore 1/3 of the volume of a cylinder with the same height and base radius.

The volume of a paraboloid can be expressed as:

The formula for a paraboloid's volume is Vparaboloid = (π/3) x (r²) x h, where r is the base's radius and h is the object's height.

A cylinder's volume can be expressed as follows with the same height and base radius:

Vcylinder = π x (r²) x h.

A paraboloid's volume to a cylinder's volume with the same height and base radius is calculated as follows:

Vparaboloid / Vcylinder = (π/3) x (r²) x h / (π x (r²) x h) = (π/3) / π = 1/3.

The volume of a paraboloid is therefore 1/3 of the volume of a cylinder with the same height and base radius.

The completely factorized form of the expression q² - 4 is (q + 2)(q - 2).

Given the expression in the question:

q² - 4

To factorize the expression q² - 4 completely, we can use the formula for the difference of squares.

The difference of squares formula states that :

a² - b² can be factored as (a + b)(a - b).

Given that:

q² - 4

Replace 4 with 2²
q² - 2²

From this expression, let a = x and b = 2

a² - b² =  (a + b)(a - b)

q² - 2² = (q + 2)(q - 2)

Therefore, the factored form is (q + 2)(q - 2).

Answer:

The answer is 9.4 cm.

Step-by-step explanation:

To solve for the circumference of the circle, use the circumference formula, which is C = 2 \(\pi\) \(r\).

Next, in the problem, the circle has a diameter measure but no radius measure. To find the radius of this circle, divide the diameter (3 cm) by 2, and it will equal 1.5 cm. The radius is being divided by 2 because the radius of any circle is equal to half the diameter of the circle.  

Then, plug in the information given from the problem into the formula, and the formula will look like C = (2) (\(\pi\)) (1.5 cm).

Finally, solve the equation, and the answer is 9.4 cm.

Answer:

348 in^2

Step-by-step explanation:

First you find the surface area for each face

The sides is 8*6

The front and back is 8*9

The top and bottom is 6*9

You then double each number of each face since there is 2 sides of each

8*6=48 * 2 = 96

8*9=72 * 2 = 144

6*9=54 * 2 = 108

Then you all them all together

96 + 144 + 108 = 348

Each friend had originally 13 action figures before buying 11 more.

Given that there are 5 friends and each of them has x action figures in his or her collection. When they buy 11 more action figures, the total number of action figures they will have is 120.

a) We need to find an equation that models the problem. Let x be the original number of action figures that each friend had.

Therefore, the total number of action figures that each friend will have after purchasing 11 more is x + 11.

The total number of action figures will be 5(x + 11) = 5x + 55.

Now, according to the problem,5x + 55 = 120

This is our equation that models the problem.

b) We have to solve the equation 5x + 55 = 120 to find the original number of action figures, x, that each friend had before buying 11 more action figures.

5x + 55 = 120

5x = 120 - 55 (subtract 55 from both sides)

5x = 65x = 13

Therefore, each friend had originally 13 action figures before buying 11 more.

12 - 12 + 8 = 14x - 8x

8 = 6x

x = 8/6

x = 4/3

Answer:

\(12 - 14x = - 8 - 1(8x - 12) \\ 12 - 14x = - 8 - 8x + 12 \\ 12 - 12 + 8 = - 8x + 14x \\ 8 = 6x \\ x = \frac{4}{3} \)

Answer:

The expected number of keys she will try before she opens the door is 4.5.

Step-by-step explanation:

Probability of opening with the first key:

One key out of 8 working, so: 1/8 probability of opening with the first key, that is:

\(P(X = 1) = \frac{1}{8}\)

Probability of opening with the second key:

Doesn't work on the first(7/8 probability), works on the second(1/7 probability). So

\(P(X = 2) = \frac{7}{8}*\frac{1}{7} = \frac{1}{8}\)

Following the logic:

For each value of x from 1 to 8, we have that \(P(X = x) = \frac{1}{8}\)

Find the expected number of keys she will try before she opens the door.

Each outcome multiplied by its probability. So

\(E(X) = 1\frac{1}{8} + 2\frac{1}{8} + 3\frac{1}{8} + 4\frac{1}{8} + 5\frac{1}{8} + 6\frac{1}{8} + 7\frac{1}{8} + 8\frac{1}{8} = \frac{1+2+3+4+5+6+7+8}{8} = 4.5\)

The expected number of keys she will try before she opens the door is 4.5.

In order for the account value to reach $91,000 in 12 years, Fwam would therefore need to invest $39,165.95, to the closest hundred dollars, assuming the interest rate is 5.9% compounded daily.

In exchange for using borrowed funds or assets, a borrower must pay the lender interest. It is charged for a certain duration of time, typically until the loan is fully returned, and is typically stated as a percentage of the amount borrowed. This fee is known as the interest rate. For instance, if a bank lends you $1,000 at a 5% annual interest rate, after a year of borrowing the money you would still owe the bank $50 more in interest. The creditworthiness of the borrower, the risk of the loan, and current market conditions are frequently used to establish the interest rate.

given

We know that Fwam expects the account to be worth $91,000 in 12 years and that the interest rate is 5.9% compounded daily in this situation.

We must convert the interest rate and the time period to the proper units before we can use the formula.

We begin by converting the 5.9% yearly interest rate to a daily rate:

daily rate is equal to (1 + 0.059/365)(365/365)-(1-1) = 0.00015999.

4,380 days in 12 years, or 365 days per year.

We can now enter the values into the formula to find P:

$91,000 = P × 2.3226

P = $39,165.95

In order for the account value to reach $91,000 in 12 years, Fwam would therefore need to invest $39,165.95, to the closest hundred dollars, assuming the interest rate is 5.9% compounded daily.
