Answer:

D is the right choice and no you cannot fit the pizza inside the box.

Step-by-step explanation:

D is the answer because to turn 2/3 into a decimal you would divide 2 by 3 and the answer you would get would be 0.66666666666...You would then add 12 to the answer and get 12.6666... Once you get this answer you would round it to the hundredths to get 12.67 but since that is not an option you could use D, 12.66 inches.

Answer:

I believe the answer is D.

Step-by-step explanation:

1. Find the area of the triangle.

The triangle is a right triangle so you can use the pythagorean theorem (a² + b² = c²).

It might be helpful to draw the line on the third side of the triangle to see it better.

The missing side is the hypotenuse, also c².

Plug in the values.

5² + 7² = c²

c² = 74

If you square root, c = √74 ≈ 8.6

However, we do not need to use this value to find the area of the triangle. Finding the hypotenuse is important for later steps.

To find the area of the triangle, we can use the formula A = 1/2bh

or A = 1/2(L)(W)

A = 1/2(5)(7)

A = 17.5

3. Find the area of the square.

Use the value from the previous step, 8.6 as the length for each side of the square (all four sides of a square are equal).

To find the area, multiply the length by the width.

A = L × W

Or use the formula A = S² since we know all sides of a square are equal.

A = 8.6 × 8.6 or

A = 8.6²

A = 73.96

4. Find the area of the semicircle.

To find the area of a circle, we use the formula A = πr²

To find the area of a semicircle, we will divide by half or multiply by 1/2.

A = 1/2πr²

Once again, we will use the value 8.6.

8.6 represents the diameter of the circle.

The diameter is double the radius, so we need to divide 8.6 by 2 to find the radius of the circle.

D = 2r

8.6 = 2r

r = 4.3

Plus the r value 4.3 into the previous formula for the semicircle.

A = 1.2π(4.3)²

A = 69.7

*Keep in mind these values are rounded so answer will not be exact.*

5. To find the combined area of the figure, add up the area of the triangle, square, and semicircle.

17.5 + 73.96 + 69.7 = 161.16

If you round to the nearest whole number, the area of the figure is 161 cm².

6. We already know the values for the sides of the triangle and square. To find the value for the semicircle, we can use the circumference formula (divided by 2 for a semicircle): C = 2πr --> C = πr

C = π(4.3)

C = 13.5

7. To find the perimeter of the entire shape, we will add up the value of all the sides.

5 + 7 + 8.6 + 8.6 + 13.5 = 42.7

If you round to the nearest whole number, the perimeter of the figure is 43 cm.

Answer: ETU

Step-by-step explanation:

When you are writing a similarity statement, you must put the letters of both triangles in the same order. In other words, you must make the first letter of the first triangle match with the first letter of the second triangle, and so on.

In this figure, \(\angle K\cong\angle E\), \(\angle L\cong\angle T\), and \(\angle KUL\cong\angle EUT\). Hence,

\(\triangle KLU \sim \triangle ETU\)

Since K is first, E is also first, as ∠K matches to ∠E. Since L is second, T is also second, as ∠L matches to angle ∠T.

Answer:

GCF is 18 and Factor is: 18(x-2)

Step-by-step explanation:

To Factor 18x-36, you want to find the GCF. So the GCF here is 18. So let's spilt 18 out of each term.

18x+18(-2)

18(x-2)

So the factoring answer is 18(x-2)

The GCF is 18.

Answer:18

Step-by-step explanation:

the GCF is 18.

Step-by-step explanation:

To solve the system of linear equations by substitution, we'll use the equation 5y = 10 to solve for y. We'll substitute this value of y into the second equation to get an equation in terms of x. Then, we'll solve for x and substitute the value of x back into one of the equations to find y.

Starting with the first equation:

5y = 10

y = 2

Next, we'll substitute this value of y into the second equation:

x - 3y = 4

x - 3(2) = 4

x - 6 = 4

x = 10

Now that we have found x, we can substitute it back into one of the equations to find y:

5y = 10

y = 2

So the solution to the system of linear equations is (x, y) = (10, 2).

Answer: (x, y) = (10 , 2)

Step-by-step explanation: 1. Solve the equation for y: {y=2

                                                                                            {x-3y=4

2. Substitute the given value of y into the equation x-3y=4: x-3x2=4

3. Solve the equation for x: x=10

4. The possible solution of the system is the ordered pair (x, y): (x, y)=(10, 2)

5. Check if the given ordered pair is the solution of the system of equations: {5x2=10

                  {10-3x2=4

6. Simplify the equalities: {10=10

                                             {4=4

7. Since all of the equalities are true, the ordered pair is the solution of the system. --> (x, y)=(10, 2)

So then, in conclusion, the solution must be, (x, y)=(10, 2).

Answer:

\(351.8mi^2\)

Step-by-step explanation:

Hey there!

Well the formula to find the surface area of a cylinder is,

\(2\pi rh+2\pi r^2\),

So with the h and r being 10 and 4 lets plug it in.

\(2\pi (4)(10)+2\pi (4)^2\)

Let's solve!

2π40 + 2π16

80π + 32π

251.3 + 100.5

= \(351.8mi^2\)

Hope this helps :)

Answer:

351.9 mi^2

Step-by-step explanation:

The surface area of a cylinder can be found using the following formula.

\(SA=2\pi r^2+2\pi rh\)

We know that the height of the cylinder is 10 miles and the radius is 4 miles.

h= 10 mi

r= 4 mi

\(SA=2\pi (4 mi)^2+2\pi (4 mi)(10 mi)\)

First, evaluate the exponent 4 mi^2.

4 mi^2= 4 mi * 4 mi = 16 mi^2

\(SA=2\pi 16 mi^2+2\pi (4 mi)(10 mi)\)

Next, multiply 16 and 2pi

\(SA=100.530965 mi^2+2\pi(4 mi)(10mi)\)

Next, multiply 4 and 10

\(SA=100.530965 mi^2+2\pi40mi^2\)

Multiply 40 and 2 pi

\(SA=100.530965 mi^2+251.327412mi^2\)

Add the 2 numbers together

\(SA=351.858377 mi^2\)

Round to the nearest tenth. The 5 in the hundredth place tells us to round the 8 to a 9 in the tenth place.

\(SA=351.9 mi^2\)

The surface area of the cylinder is about 351.9 square miles.

Answer:

| a - b | < length of third side < a + b

Step-by-step explanation:

Visualize the two given sides of the triangle (let's call then a and b), joined at the vertex of the triangle, and forming an angle. We can join the other free end of these two segments, with another segment whose length would vary according to how tiny or large the angle is. We can spread the aperture of the angle they form as much as we can just below  (not reaching this angle measure, because in such case, there will be no triangle of tangible area. In such case, the length of the joining segment will be limited by the addition of the two sides:

length of third side < a + b

In the case the aperture of the angle formed by the two given sides is diminished as much as possible to still form a measurable triangle, the angle has to be just larger than zero, and in such case, the segment joining the other to ends of a and b would be just larger than the absolute value of the difference between a and b:

length third side > | a - b|

These are the two extreme cases, and the length of the third side must be within these limits.

True answers: Have 6 Straight Sides, Equal sides, And 6 Vertices

B because there are 12 inches in a foot. Do you need to divide 84÷12=7 which means Circle B is bigger

Answer:

Circle B

Step-by-step explanation:

Let's first convert the circumference of Circle B to feet:

84/12=7 ft

Now we find the diameter:

C = πd

7 ft = πd

d = 7/π

d = 2.23 feet (approximately, 3.14 for π)

Therefore Circle B is bigger as it has a larger diameter.

Answer:

6.68 units (2 d.p.)

Step-by-step explanation:

The formula for the volume of a cylinder is:

\(\boxed{V=\pi r^2 h}\)

where:

Given values:

To find the height of the cylinder, substitute the given values into the formula and solve for h:

\(\implies 189=\pi \cdot 3^2 \cdot h\)

\(\implies 189=9\pi \cdot h\)

\(\implies \dfrac{189}{9 \pi}=\dfrac{9\pi \cdot h}{9 \pi}\)

\(\implies \dfrac{189}{9 \pi}=h\)

\(\implies h=6.6845076...\)

Therefore, the height of a cylinder with a radius of 3 units and a volume of 189 cubic units is 6.68 units (2 d.p.).

Answer:

h≈6.68

Step-by-step explanation:

6.68 is the height of a cylinder with a radius of 3 and a volume of 189

Step-by-step explanation:

The difference beteen 9.2 ounces and 8.1 ounces is  1.1 ounces

   and the difference in price is   .49

       so 1.1 ounces cost .49

           $ .49 / 1.1 oz = $  .445  per ounce

Then Reid's bowl should cost   7.8 oz  * $ .445 / oz = $3.47

Hi there!

According to the question,

Jim drove 804 miles in 12 hours

For 1 mile it will take him \(\frac{12}{804}\) hours

For 603 miles it will take him  \(\frac{12}{804}\) * 603 hours

Therefore it would take him 9 hours to drive 603 miles.
