Answer:

The correct answer is A) $7.00

Step-by-step explanation:

In order to determine that, you can use any two points and the slope formula. For the purpose of this, we'll use (1, 39) and (3, 53)

m(slope) = (y2 - y1)/(x2 - x1)

m = (53 - 39)/(3 - 1)

m = 14/2

m = 7

A rectangle is 6yards longer than it is wide. Find the dimensions of the rectangle if it’s area is 187 square yards

emmasim [6.3K]

Answer:

Width = 11 yards

Length = 17 yards

Step-by-step explanation:

First of all, the length of the rectangle is 6 yards longer than the width, this means, length = width + 6 yards. This dimensions can be represented on figure 1, where w is width, and l, for length.

We know the area of a rectangle is A = width x length

For our case 187 = w . (w + 6)

Using the Distributive Property for the multiplication we obtain

$187 = w^{2} +6w$

$w^{2} +6w-187 =0,$

Using the quadratic formula $w=\frac{-b\±\sqrt{b^{2}-4ac } }{2a}$ where a = 1, b = 6, c = - 187 and replacing into the formula, we will have:

$w=\frac{-6\±\sqrt{6^2-4(1)(-187)} }{2(1)}$

$w=\frac{-6\±\sqrt{36+748} }{2}=\frac{-6\±\sqrt{784} }{2}=\frac{-6\±28}{2}$

We have two options: $w=\frac{-6+28}{2}=\frac{22}{2}=11 yards$

$w=\frac{-6-28}{2}=\frac{-34}{2}=-17 yards$ But a distance (width) can not be negative so, this answer for w must be discarded.

The answer must be width = 11 yards.

To find the length $l =\frac{187}{11}=17 yards$

Answer:

Hello your question is not well written attached below is the complete question

answer :

a) smallest value = $0.405 million

largest value = $22 million

b) smallest value = $0.505 million

largest value = $9.332 million

Step-by-step explanation:

A) what are the smallest and largest yearly salary values in the population

smallest value = $0.405 million

largest value = $22 million

b) What are the smallest and largest sample mean in the sampling distribution

Smallest value = $0.505 million

Largest value = $9.332 million

note : values where gotten using statkey on the dataset NFLcontracts2015 as stated in the attached document ( question )

Please help!!!! i am despite, i will mark brainlyest

Sedaia [141]

Answer:

x=12

10x = 120

5x = 60

Step-by-step explanation:

paralellograms will become 360 degrees

so 2(5x) +2(10x)= 360

Simplify:

10x + 20x = 360

= 30x

divide both sides by 30 and isolate

30x = 360

30 30

x=12

multiply 12 by 10x and 5x

10x = 120

5x = 60
