3 0

Answer:

Step-by-step explanation:

Percent means "per hundred" or "out of one hundred." While B) is out of one hundred, turn it into a percent, and the percentage would be .95%. A) and C) are not out of 100, so those answers are not applicable. The only answer left is D), which is correct, because 95/100 is equivalent to 95%.

A sporting good store sells basketballs and footballs. Gavin pay $44 dollars for 3 basketballs and 2 footballs. Andrew pays $31

zzz [600]

Answer: The price of 1 football = $ 7 and price of 1 basket ball= $10

Step-by-step explanation:

Let x = price of 1 football.

y = price of 1 basketball.

As per given,

$3x+2y=44\ \ \ (i)$

$x+3y=31\ \ \ \ (ii)$

Multiply 3 to (ii) , we get

$3x+9y=93\ \ \ \ (iii)$

Eliminate (i) from (iii)

$7y=49\\\\\Rightarrow\ y=7$

Put this in (ii), we get

$x+3(7)=31\\\\\Rightarrow\ x+21=31\\\\\Rightarrow\ x=31-21=10\\\\\Rightarrow\ x=10$

Hence, the price of 1 football = $ 7 and price of 1 basket ball= $10

Find the distance between points A (10,-1) and B (-2,5). Round to the nearest tenth

bija089 [108]

Answer:

<h2>The answer is 13.4 units</h2>

Step-by-step explanation:

The distance between two points can be found by using the formula

$d = \sqrt{ ({x1 - x2})^{2} + ({y1 - y2})^{2} } \\$

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

A (10,-1) and B (-2,5)

The distance is

$|AB| = \sqrt{ ({10 + 2})^{2} + ({ - 1 - 5})^{2} } \\ = \sqrt{ {12}^{2} + ({ - 6})^{2} } \\ = \sqrt{144 + 36} \: \: \: \: \: \: \: \\ = \sqrt{180} \\ = 6 \sqrt{5} \: \: \\ =13.416407$

We have the final answer as

<h3>13.4 units to the nearest tenth</h3>

Hope this helps you
