Step-by-step explanation: Find your answer by multiplying the 2 percent's.

Let p, equal percent.

800000000.0%x9000000.0% = p

800000000.0%x9000000.0% = 720,000,000,000

2y + 4x = 16

Anyone know how to solve for Y?

Answers

Answer:

y = -2x + 8

Step-by-step explanation:

In this question, you have to solve for "y".

Solve:

2y + 4x = 16

Get "y" by itself by subtracting 4x from both sides.

2y = -4x + 16

Simplify by dividing both sides by 2.

y = -2x + 8

The mean of the heights of three buildings A,B and C is 14.2m. The mean of the heights of five buildings A,B,C, D and E is 14.8m. Find the mean of the heights of the buildings D and E.

Answers

Answer:  15.7 meters

========================================================

Work Shown:

s = sum of the heights of buildings A,B,C

s/3 = mean of the heights of buildings A,B,C

s/3 = 14.2

s = 3*14.2

s = 42.6

The buildings A,B,C have their heights add up to 42.6

--------------

r = sum of the heights of buildings A,B,C,D,E

r/5 = mean of the heights of buildings A,B,C,D,E

r/5 = 14.8

r = 5*14.8

r = 74

--------------

r-s = (sum of heights of A,B,C,D,E)-(sum of heights of A,B,C)

r-s = sum of the heights of buildings D and E

r-s = 74-42.6

r-s = 31.4

(r-s)/2 = mean height of buildings D and E

(r-s)/2 = 31.4/2

(r-s)/2 = 15.7 meters is the average height of buildings D and E.

B В-

b) Calculate BC.

Answers

Answer:

a) 11.4

Step-by-step explanation:

cos42=0.74

d²=c²+a²-2caCosD

d²=17²+13²-2×17×13×Cos42

d²=17²+13²-328.47

d²=289+169-328.47

d²=458-328.37

d=√129.63

d=11.4

The length of AC is 11.4 cm and the length of BC is 30.9 cm after solving through trigonometric ratios.

What are trigonometric ratios?

Trigonometric ratios deal with the sides and angles in a right angled triangle. sin, cos, tangent ,cosecant ,secant and cotangent are trigonometric ratios.

How to find the length of side of triangle?

ABC and ACD are triangle,

The value of AC will be:

According to cosine formula:

[tex]AC^{2} =AD^{2} +AC^{2} -2AD*AC*Cos D.[/tex]

[tex]AC^{2} =17^{2} +13^{2} -2*17*13* cos 42[/tex]

[tex]AC^{2} =[/tex]289+169-328.47

[tex]AC^{2}[/tex]=129.52

AC=11.4 cm

The value of BC will be as under:

using the sine rule

BC/sin A=CA/sin B=AB/sinC

BC/sin76=11.4/sin 21=AB/sin83

from the first 2 in equal to form

BC/sin 76=11.4/sin 21

BC=30.9

Hence the length of AC=11.4 cm and BC=30.9 cm.

Replace the values of A, b, x, and y to write an exponential equation that represents the number of cells present at h hours.

Answers

Answer:

100(2)^h =6,400

Step-by-step explanation:

For an equation in the form A(b)^x=y , A represents the initial amount, and b represents the growth rate. At 0 hours, there were 100 cells, so A=100 .

Between 0 hours and 1 hour, the number of cells doubled from 100 to 200, or 100(2). Between 1 and 2 hours, the number of cells again doubled from 200 to 400, or 100(2)^2 . So the growth rate, or b, is 2.

The table shows that at h hours, there were 6,400 cells. Therefore, the equation that represents the number of cells at h hours is 100(2)^h =6,400.

A rectangular lawn has a perimeter of 15.8 meters and the length is 3.1 meters longer than the width. What are the dimensions of the lawn? If the width of the fixture is w meters, find w to one decimal place.

Answers

Answer:

w is 4.8 meters

Step-by-step explanation:

-perimeter is 15.8 m so all the sides of the rectangle adds up to 15.8.

- a rectangle has 2 sets of equal sides.

-first, do 3.1 times 2 to get the length of the first set of equal sides. This equals to 6.2.

-now 15.8 - 6.2 = 9.6 meters

- 9.6 divided by 2 to find the width, as well as the measurements of the second set of equal sides.

the width, w, is 4.8 meters.

2W + 2(W + 3.1) = 15.8
2W + 2W + 6.2 = 15.8
4W + 6.2 = 15.8
4W = 9.6
W = 2.4

Perimeter
2.4 + 2.4 + (2.4 + 3.1) + (2.4 + 3.1) = 15.8

Hilary sells makeup, primarily lipsticks and eye shadows. She sells the lipsticks for $10 and the eye shadows for $5. At a home show, she wants to sell at least $120 of these two products, knowing she has at most 20 items in her inventory that are either lipsticks or eye shadows.

She makes $7 on every lipstick and $3 on every eye shadow she sells. Use the information below:

Let x = lipsticks
Let y = eye shadows

Then $10x + $5y > $120
and x + y < 20.

The graph of these functions is shown to the right. It is impossible to sell a negative number of makeup items, so x and y both have to be greater than zero. Therefore, the functions are confined to the first quadrant.

Profit function:
P = $7x + $3y

How many lipsticks and eye shadows should be sold to maximize the total profit?
A.
The profit is maximized when 20 lipsticks and 0 eye shadows are sold.

B.
The profit is maximized when 12 lipsticks and 0 eye shadows are sold.

C.
The profit is maximized when 16 lipsticks and 4 eye shadows are sold.

D.
The profit is maximized when 4 lipsticks and 16 eye shadows are sold.

A coral reef grew 7 meters.

Step-by-step explanation:

The prefix "milli" before any standard  unit such as meters, grams, or seconds and etc., It means it takes 1000 milli units to make 1 standard unit. Example:

1 meter= 1 millimeters.

To solve this problem you need to cross multiply:

7000 millimeters              1 meter    

                       multiply                 = 7 meters

1 month              1000 millimeters

Units that are the same and diagonal from each other cancel out.  

So the answer is: Last month, A coral reef grew 7 meters.
