Answer:

  18 in

Step-by-step explanation:

The volume of each container is the product of its dimensions:

  V = LWH

We can let h represent the unknown height of Container 2. The volumes are equal when ...

  32·18·12 = 24·16·h

  (32·12·18)/(16·24) = h =18 . . . . . divide by the coefficient of h, simplify

The missing height of Container 2 is 18 inches.

Check your answer. Is $15.75 a reasonable amount of interest? If Caroline had invested the $900 for a full year at 2% interest, the amount of interest would have been $18. Yes, $15.75 is reasonable.

Answer:

Given : The high school stadium contains a track that surrounds a soccer field. The soccer field is 100 yards long and 70 yards wide.

The school decided to cover the semicircles with grass to create a space for stretching and other activities.

To Find: area of one of the semicircles at either end of the track

How many square yards of grass will the school need to cover the entire circle?

Solution:

Diameter of semicircle = 70 yards

Radius of semicircle = 70/2 = 35 yards

Area of semicircle at one end = (1/2)πr²

= (1/2)(22/7)35²

= 1,925 sq yards

area of one of the semicircles at either end of the track = 1,925 sq yards

square yards of grass will the school need to cover the entire circle

= 2 x   1,925

= 3850 sq yards

distance around one of the semicircles at either end of the soccer field = πr  = (22/7) 35 = 110 yards

distance around the inner lane of the track  = 100 + 100 + 110 + 110

= 420 yards

Answer:

A) 217.75 sales tax

B)281.40 he will pay on the loan

C)$3849.15 he will pay including total cost, interest, and tax

Step-by-step explanation:

A)

To find sales tax, multiply the price by its percentage. 6.5% in decimal is 0.065. 3350x0.065=217.75 for its sales tax.

B)

This is the same for loan.

3350x0.084=281.40 he will pay for loan.

C)

Now add it all up. 3350+217.75+281.40=3849.15

Answer:

The correct answers are:

a. $217.75!

b. $281.40!

c. $3,849.15!

Step-by-step explanation:

a. Find the sales tax by multiplying the price by its percentage (6.5%, 0.065 in decimal form)

3,350 x 0.065=217.75

so the sales tax is $217.75

b. This is the same as finding tax. Find the loan by multiplying the original price by the percentage (8.4%, 0.084 in decimal form).

3,350 x 0.084 = 281.40

so the loan is $281.40

c. This time, sum the original price with both the loan and sales tax.

3,350 + 217.75+ 281.40= 3849.15

so the total cost for the new tractor is $3,849.15

answer: B,C

Step-by-step explanation:

to be able to reproduce sexually you need enough of the same species to mate with. A says no individuals to reproduce with but for that it would be better if they were asexual. D says they change living environment and that usually changes the amount of same species animals that are around to reproduce with.

Answer:

65^2

Step-by-step explanation:

if you woulndt mind giving me brainliest im trying to rank up, only if u dont mind.

#1:

Between 8 cm and 9 cm

Work:

SA = 6s^2  

390 = 6 s^2

390/6 = 6s^2 /6

65 = s^2

sqrt(65) = s

s = 8.06

The total surface area of the triangular pyramid is 107 * square feet.

What is a triangular pyramid?

Take a triangle. This is a base. Now take 3 triangles such that each of them are connected to one-one side of the first triangle and when they're taken together, they form a closed object, called as a triangular pyramid.

We are given that;

The length of median from outer triangle to side of the inner triangle is 8 ft

Side of inner equilateral triangle is 12 ft

Now,

First, we can find the height of the outer equilateral triangle using the Pythagorean theorem:

a is half the length of the side of the inner triangle (6 ft), m is the length of the median (8 ft), and b is the length of the side of the outer triangle (unknown).

a^2 + (m/2)^2 = b^2

b^2 = 6^2 + 8^2/4

b^2 = 36 + 4

b^2 = 40

b = sqrt(40)

b = 2 * sqrt(10)

So the height of the outer triangle is:

h = b * sqrt(3)/2

h = sqrt(30)

Now we can find the area of each equilateral triangle using the formula:

A = (sqrt(3)/4) * s^2

For the inner triangle:

A_inner = (sqrt(3)/4) * 12^2

A_inner = 36 * sqrt(3)

For the outer triangle:

Now we can find the area of the base, which is just the area of the inner equilateral triangle:

A_base = A_inner

A_base = 36 *

Finally, we can find the surface area of the triangular pyramid by adding the areas of the four triangles and the base:

SA = A_inner + 3 * A_outer + A_base

If anything is confusing, let me know and I'll explain it more.

Answer:y = 1.5x + 4.0

Step-by-step explanation:

This is because the equation relates the distance traveled (y) to the time elapsed (x) through a linear relationship with a slope of 1.5, which represents the object's speed in meters per second, and a y-intercept of 4.0 meters, which represents the initial position of the object at time zero.

I'm pretty sure.

The equation that describes the motion of the object is y = 2x (option a)

Let's calculate the slope (m) using the values from the table. We take any two points (x₁, y₁) and (x₂, y₂) from the table:

(x₁, y₁) = (1, 2.0)

(x₂, y₂) = (5, 10.0)

The slope (m) is given by:

m = (y₂ - y₁) / (x₂ - x₁)

m = (10.0 - 2.0) / (5 - 1)

m = 8.0 / 4

m = 2.0

Now that we have the slope (m), we can determine the equation:

y = mx + b

Using one of the points from the table (1, 2.0) and the calculated slope (m = 2.0), we can solve for the y-intercept (b):

2.0 = 2.0 * 1 + b

2.0 = 2.0 + b

b = 2.0 - 2.0

b = 0

So, the Answer is option (a) y = 2x
