Find the distance between A(–3, 5) and B(4, 2), to the nearest hundredth.

sergij07 [2.7K]

Answer:

$d=7.62$

Step-by-step explanation:

Start with the distance formula:

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Identify your values.

$x_1=-3\\x_2=4\\y_1=5\\y_2=2$

Substitute.

$d=\sqrt{(4-(-3)^2+(2-5)^2}$

The $-3$ becomes positive as it's being multiplied by a negative.

$d=\sqrt{(4+3)^2+(2-5)^2}$

Solve what is in parentheses.

$d=\sqrt{(7)^2+(-3)^2}$

Square what is in parentheses.

$d=\sqrt{49+9}$

Add.

$d=\sqrt{58}$

Find the square root (I usually do four digits after the decimal).

$d=7.6157$

Round to the nearest hundredth.

$d=7.62$

A movie theater buys popcorn kernals for $5.88 per pound. (A) Which equation shows the cost of popcorn kernals? (B) what is the

inessss [21]

Answer:

Given that the manager of Theatre A says that they usually go through about 15 cups of popcorn kernels and about 5 cups of oil each weeknight.

Then, the ratio value of oil to popcorn kernels for theatre A is 5 / 15 = 1 / 5.

Given that the manager of Theatre B says that they order 18 cups of oil and 72 cups of popcorn kernels each week.

Then, the ratio value of oil to popcorn kernels for theatre B is 18 / 72 = 1 / 4.

Given that the manager of Theatre C says that their concessions use 6 cups of oil and 32 cups of popcorn kernels on a busy Saturday.

Then, the ratio value of oil to popcorn kernels for theatre C is 6 / 32 = 3 / 16.

Mary mixes white paint and blue paint in the ratio 2:3

Sedbober [7]

Given:

Ratio of white and blue paint is 2:3

Total quantity of paint is 20 litres

To find:

Quantity of blue paint to be mixed so that the ratio of white paint to blue paint becomes 1:7

Solution:

The ratio 2:3 totals 20 that is $2x+3x=20\rightarrow5x=20\rightarrow x=4$

So, the quantity of white paint in the mixture is $2\times4=8$ and the quantity of blue paint in the mixture is $3\times4=12$

Now, to get the final ratio as 1:7, Mary should have $7\times8=56 \text{ litres }$ of blue paint. So, she need to add $56-12=44 \text{ litres}$ .

Therefore, Mary has to add 44 litres of blue paint to the mixture to make the ratio as 1:7.

A student needs to make a square cardboard piece. The cardboard should have a perimeter equal to at least 92 inches. The functio

saveliy_v [14]

Answer: d. s ≥ 23

Step-by-step explanation:

Let s be the side of the square.

We know that the perimeter of a square =4s

Let f(s)=4s

If the cardboard should have a perimeter equal to at least 92 inches, the inequality would look like

$4s\geq 92$

Divide both sides by 4, we get

$s\geq\frac{92}{4}\\\Rightarrow\ s\geq23$

Thus, d. is the right answer. The reasonable domain of f(s) is $s\geq23$
