what is 21 divided by 3 + (8 -2 +2)

Answer:

25 cm

Step-by-step explanation:

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

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

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:

To help Its sales, the company should focus on producing Large

T-shirts. Approximately 80% of T-shirts the company

makes should be medium and large T-shirts to match the market preference. If the total number of T-shirts sold in a month is 45,000, 3,300

of these will likely be size small.

Step-by-step explanation:

In the survey, Large t-shirts are most frequently bought so they should be the primary focus if the company is trying to make more money.

To find the percentage of shirts that the medium and large shirts make up, first you find the total amount of shirts (11+37+83+19=150), then you will find how many mediuma and large shirts (37+83=120). Percentage is (120/150)*100=80%

To find the number of small shirts you can set up a proportion.

[tex]\frac{11}{150} =\frac{x}{45,000}[/tex], then cross multiply

150x=11*45,000

150x=495,000

x=3,300

Step-by-step explanation:

Answer:

This is the correct answer

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
