Answer:

176

Step-by-step explanation:

option a ( 176 cm²)

A trapezoid has a base of 12 centimeters, a height of 16 centimeters, and a top side length of 10 centimeters.

To find the area, we use the formula for the area of a trapezoid:

Area = 1/2 × (Base1 + Base2) × Height

Here, Base1 is 12 cm,

Base2 is 10 cm, and

the height is 16 cm.

the sum of the bases:

12 cm + 10 cm

= 22 cm.

Multiply by the height:

22 cm × 16 cm

= 352 cm².

Divide by 2 to get the area:

352 cm² ÷ 2

= 176 cm².

So, the area of the trapezoid is 176 cm².

-7 = -1 + [tex]\frac{x}{3}[/tex]

To solve this you must isolate x.

On the right side of the equation the one is negative. To cancel the -1 from the right side you must add 1 to both sides (what you do to one side you do to the other) since addition is the opposite of subtraction (negative). Doing this will make -1 zero on the right side of the equation and bring it over to the left side

-7 + 1 = -1 + 1 +  [tex]\frac{x}{3}[/tex]

-6 = 0 +  [tex]\frac{x}{3}[/tex]

-6 =  [tex]\frac{x}{3}[/tex]

The x is being divided by 3 and the opposite of division is multiplication.  To completely isolate x you must multiply 3 to both sides. This will cancel the three out on the right side of the equation and bring it over the left side.

-6 * 3 = [tex]\frac{x}{3}[/tex] * 3

-18 = x

Now check:

-7 = -1 + [tex]\frac{-18}{3}[/tex]

-7 = -1 + (-6)

-7 = -7

^^^This is true which means that x = -18

I hope this helped! Let me know if you have any questions

Answer:

The radius of the cylinder is (1/2)x units

The area of the cylinder’s base is (1/4)πx2 square units

The height of the cylinder is 4x units

Step-by-step explanation:

The complete question is

A cylinder with a base diameter of x units has a volume of πx3 cubic units.

Which statements about the cylinder are true? Check all that apply.

(1) The radius of the cylinder is (1/2)x units.

(2) The radius of the cylinder is 2x units.

(3) The area of the cylinder’s base is (1/4)πx2 square units.

(4) The area of the cylinder’s base is (1/2)πx2 square units.

(5) The height of the cylinder is 2x units.

(6) The height of the cylinder is 4x units

we know that

The volume of the cylinder is equal to

[tex]V=\pi r^{2}h[/tex]

we have

[tex]r=\frac{x}{2}\ units[/tex] ----> the radius is half the diameter

[tex]V=\pi x^{3}\ units^3[/tex]

substitute the given values  in the formula of volume

[tex]\pi x^3=\pi (\frac{x}{2})^{2}h[/tex]

solve for h

simplify

[tex]x=(\frac{1}{4})h[/tex]

[tex]h=4x\ units[/tex]

Verify each statement

(1) The radius of the cylinder is (1/2)x units

The statement is true

see the explanation

(2) The radius of the cylinder is 2x units.

The statement is false

Because, the radius of the cylinder is x/2 units

(3) The area of the cylinder’s base is (1/4)πx2 square units

The statement is true

Because, the area of the cylinder's base is equal to

[tex]A=\pi r^{2}[/tex]

[tex]r=\frac{x}{2}\ units[/tex]

substitute

[tex]A=\pi (\frac{x}{2})^{2}[/tex]

[tex]A=\frac{\pi x^2}{4}\ units^2[/tex]

(4) The area of the cylinder’s base is (1/2)πx2 square units.

The statement is false

Because, the area of the cylinder's base is equal to

[tex]A=\frac{\pi x^2}{4}\ units^2[/tex]

see the part (3)

(5) The height of the cylinder is 2x units.

The statement is false

Because, the height of the cylinder is 4x units (see the explanation)

(6) The height of the cylinder is 4x units

The statement is true

see the explanation

Answer: 70 miles long

Step-by-step explanation:

7/10 x 100 = 70

its 70 miles long

Final answer:

The great bicycle race is 70 miles long.

Explanation:

To find the length of the great bicycle race, we need to multiply the length of the 100-mile astounding race by 7/10. Since 7/10 is a fraction, we can represent it as 7 divided by 10. Multiplying by a fraction is the same as multiplying the numerator by the same factor as the denominator. Therefore, we can multiply 100 by 7 and divide by 10 to find the length of the great bicycle race.

There are a few ways to do this computation. One way is to multiply 100 by 7, which equals 700, and then divide 700 by 10. The result is 70 miles. Therefore, the great bicycle race is 70 miles long.

Answer:

The rigth answer is, ( 5/2 , -1 )

Step-by-step explanation:

To find the midpoint we use the respective formula:

m = ( x1 + x2 / 2 ,  y1 + y2 / 2 )

We replace:

m = ( 1 + 4/2  ,  3 + (- 5) / 2 )

We solve:

m = ( 5/2 ,  -1 )

Answer:

minimum value = 10

Step-by-step explanation:

The equation of a parabola in vertex form is

y = a(x - h)² + k

where (h, k) are the coordinates of the vertex and a is a multiplier

To obtain this form using completing the square

add/subtract ( half the coefficient of the x- term )² to x² - 6x

f(x) = x² + 2(- 3)x + 9 - 9 + 19

     = (x - 3)² + 10 ← in vertex form

with (h, k) = (3, 10 )

To determine maximum or minimum consider the value of a

• If a > 0 then minimum value of k

• If a < 0 then maximum value of k

Here a = 1 > 0, hence minimum value of k = 10

The total number of miles the car can travel in 6 hours is A. 6x miles per hour

To calculate the miles the car will travel in six hours

By using the formula of Distance = Rate * Time

Given that,

Average rate is given as "x" miles per hour

the time = 6 hours

To calculate the total miles in 6 hours = x * 6 miles per hour

Total miles = 6x miles per hour

Therefore, the total number of miles the car can travel in 6 hours is 6x miles per hour

Step-by-step explanation:

I know this because I just took the test

For this case we have:

A student plans to spend 2/5 of his earnings on his education. If you earn 25,000 this year, how much do you plan to spend on your education?

x: Let the variable that represents the student's earnings

y: Let the variable that represents the planned expenditure for education

If you plan to spend[tex]\frac {2} {5}[/tex] of your earnings on education we have:

[tex]y = \frac {2} {5} x[/tex]

According to the statement we have to:

[tex]x = 25,000[/tex]

So:

[tex]y = \frac {2} {5} (25000)\\y = 10,000[/tex]

Thus, the student plans to spend 10,000 on his education

Maya travels  [tex]4.19 feet/sec[/tex] faster than Kelly !

Difference in distance is : [tex]106.76-56.52 = 50.24 feet[/tex]

Step-by-step explanation:

Here we have , The Carousel in the National Mall has 4 rings of horses. Kelly is riding on the inner ring, which has a radius of 9 feet. Maya is riding on the outer ring, which is 8 feet farther out from the center than the inner ring is. We need to find In one rotation of the carousel, how much farther does Maya travel than Kelly . Let's find out:

Kelly is riding on the inner ring, which has a radius of 9 feet

Total distance traveled by Kelly is circumference of circle with radius 9 feet i.e.

⇒ [tex]Distance = 2\pi r[/tex]

⇒ [tex]Distance = 2(3.14) 9[/tex]

⇒ [tex]Distance = 56.52feet[/tex]

Maya is riding on the outer ring, which is 8 feet farther out from the center than the inner ring .

Total distance traveled by Maya is circumference of circle with radius (8+9=17) feet i.e.

⇒ [tex]Distance = 2\pi r[/tex]

⇒ [tex]Distance = 2(3.14) 17[/tex]

⇒ [tex]Distance = 106.76feet[/tex]

Therefore , Difference in distance is : [tex]106.76-56.52 = 50.24 feet[/tex]

Now , Speed of both is give by

⇒ [tex]Speed_k_e_l_l_y=\frac{56.52}{12} = 4.71 feet/sec[/tex]   And ,

⇒ [tex]Speed_M_a_y_a=\frac{106.76}{12} = 8.90 feet/sec[/tex]

Faster Maya travels = 8.90-4.71 = 4.19

So , Maya travels  [tex]4.19 feet/sec[/tex] faster than Kelly !
