Answer:

r = 200

Step-by-step explanation:

[tex]Area of sector = (\frac{225}{360})[/tex]×πr² = [tex](\frac{5}{8})[/tex] ×πr²

[tex](\frac{5}{8})[/tex] ×πr² = 250π

[tex](\frac{5}{8})[/tex] ×r²   = 250

       r²   = [tex](\frac{8}{5})[/tex] × 250

       r²   = 400

       r    = 200 (r is a length so, it's positive)

Answer: 300 ft^2

Step-by-step explanation:

First, find the area of the rectangle on the bottom:

Area of a rectangle = length * width = 18 * 12 = 216

Now, find the area of the trapezoid:

Area of a trapezoid = (base 1 + base 2) / 2 * height → (10 + 18) / 2 * 6 = 84

Add these together: 216 + 84 = 300 ft^2 :)

The number of customers who will pay by debit card will be 50.

The fraction is defined as the division of the whole part into an equal number of parts.

Last week there were

32 + 2 + 26 = 60 customers.

That means that the fraction of the customers, who paid by debit card, was

2/60  =   1/30

In situations like that, when we use historical data and try to predict future behaviour, we use that past experience and extrapolate to a predicted result.

we simply say that we expect the same fraction, 1/30 if customers use credit cards.

for the absolute number of predicted debit  card customers we multiply the predicted number of customers by the expected fraction

1500  × 1 / 30 = 1500  /  30  = 50

Therefore the number of customers who will pay by debit card will be 50.

Answer:

x = - 2, x = - 3, x = [tex]\frac{3}{2}[/tex]

Step-by-step explanation:

to find the zeros equate p(x) to zero , then

(x + 2)(2x² + 3x - 9) = 0 ← factor the quadratic

(x + 2)(x + 3)(2x - 3) = 0

equate each factor to zero and solve for x

x + 2 = 0 ⇒ x = - 2

x + 3 = 0 ⇒ x = - 3

2x - 3 = 0 ⇒ 2x = 3 ⇒ x = [tex]\frac{3}{2}[/tex]

Answer:

We are given that the total volume of the sandbox is 330 cubic feet.
We are given the side measurements of 3 feet tall and 10 feet wide.
3 x 10 = 30 sq2

V(volume)= 330 ft3

330 ft3 divided by 30 sq2 = 11ft

In conclusion, the length of the box would be:
= 11 ft

Answer:

[tex]\frac{10 \sqrt{3} }{3} = b[/tex]

Step-by-step explanation:

Hi there!

We are given a right triangle (notice the right angle), one angle with a measure of 30° and another with 60°

We are also given that one of the legs (one of the sides that makes up the right angle) is 5

We want to find what b is

This triangle is a special right triangle, a 30-60-90 triangle

In a 30-60-90 triangle, if the hypotenuse (the side opposite from the right angle) is b, the leg that is opposite from the 30° angle is [tex]\frac{b}{2}[/tex], while the leg that is opposite from the angle that is 60° is [tex]\frac{b\sqrt{3} }{2}[/tex]

In this case, we're given that the side opposite from the 60 degree angle is 5, meaning that 5 is equal to [tex]\frac{b\sqrt{3} }{2}[/tex]  

So we can set 5 equal to [tex]\frac{b\sqrt{3} }{2}[/tex], to solve for b:

5=[tex]\frac{a\sqrt{3} }{2}[/tex]

Multiply both sides by 2

5*2=b√3

10=b√3

Now divide both sides by √3

[tex]\frac{10}{\sqrt{3} } =b[/tex]

rationalize the denominator

[tex]\frac{10 * \sqrt{3} }{\sqrt{3} *\sqrt{3} }[/tex] = b

[tex]\frac{10 \sqrt{3} }{\sqrt{9}}[/tex]= b

[tex]\frac{10 \sqrt{3} }{3} = b[/tex]

The answer can be left as that.

Answer:

x=5

y=5

y = 3x - 10 -----------(1)

y=2x-5------------(2)

Step-by-step explanation:

put the value of y in 2nd equation

y=2x-5

=3x - 10=2x-5

=3x-2x=-5+10

= x=5,

now put the value of x in 1st equation.

y = 3x - 10

=y=3×5-10

=y=15-10

= y=5.

check

put the value of x and y in 1st equation.

y = 3x - 10

x=5,,y=5

=5=3×5-10

= 5=5

yes

Step-by-step explanation:

anything with 10^n multiplied by a number from 0 to 10 is

Answer: Yes

Step-by-step explanation:

Solve the system of equations by setting the two substituting the first y equation in for the second and getting: -1/3x - 4 = -2x + 1.

Now, add 2x to the left side to cancel it from the right and add 4 to the right side to cancel if from the left to get: (5/3)x = 5

Solve for x to get 3.

Plug x into the second equation (could be either equation though) and get: y = -2(3) = 1 = -5.

Thus, (3,-5) is a solution :)

The average rate of change of the height function is slope of the height function

The model's height increases by approximately 0.011 inch for every 1-cubic-inch increase in its volume.

The height function is given as:

[tex]H(V) = 2.69\sqrt[3]{V}[/tex]

When V = 512, the function becomes

[tex]H(512) = 2.69\sqrt[3]{512}[/tex]

[tex]H(512) = 21.52[/tex]

Similarly;

When V = 1000, the function becomes

[tex]H(1000) = 2.69\sqrt[3]{1000}[/tex]

[tex]H(1000) = 26.9[/tex]

The average rate of change is then calculated as:

[tex]H' = \frac{H(1000) - H(512)}{1000 - 512}[/tex]

This gives

[tex]H' = \frac{26.9 - 21.52}{1000 - 512}[/tex]

[tex]H' = \frac{5.38}{488}[/tex]

Evaluate the quotient

[tex]H' = 0.01102459016[/tex]

Approximate

[tex]H' = 0.011[/tex]

Hence, the model's height increases by approximately 0.011 inch for every 1-cubic-inch increase in its volume.
