False.
We know that $\sqrt{36} = 6$ , so $\sqrt{35}$ must be less than 6.
6 - (something less than 6) > 0

Well, the answer to the first part of the equation is 0.08392022, then you just have to decipher if 0.08392022 < 0 is true or false. For why, you could put how rounding affected the answer. Hopefully this all makes sense. :)

Answer:

My Answer: 33.95

Step-by-step explanation:

x - 13.75 = 20.2

so because it is subtracting we have to add.

x - 13.75 + 13.75 = 20.2 + 13.75

when added, x will cancel out, and we will be left with the answer.

x = 33.95

A company sells t-shirts for $6 each. They also charge a one-time processing fee of $3 per order. Jamie ordered t-shirts and pai

jenyasd209 [6]

$45-$3
you would do this to take out the processing fee.
$42/ $6
this is because each shirt cost $6
the equation would be (45-3) / 6= 7]
your answer would be 7 shirts

Answer:

2,100 miles

Step-by-step explanation:

Step 1- Find the miles the car can travel per gallon

630 miles/ 15 gallons=42 miles per gallon

Step 2- Multiply the miles per gallon by the number of gallons being used

42x50=2,100 miles

A. The perimeter of a rectangle is twice the length plus twice the width. If L represents the length and W represents the width

vampirchik [111]

Perimeter P = 2L + 2W

b. P = 2*1010 + 2*1818 = 2020 + 3636 = 5656 inches

c. Area A = WL

d Area = 1010*1818 = 1836180 in^2

What is the length side of a triangle that has vertices at (-5, -1), (-5, 5), and (3, -1)?

Rasek [7]

The side lengths of triangle are 6 units, 8 units and 10 units.

SOLUTION:

Given that, we have to find what is the length side of a triangle that has vertices at (-5, -1), (-5, 5), and (3, -1)

We know that, distance between two points $P\left(x_{1}, y_{1}\right) \text { and } Q\left(x_{2}, y_{2}\right)$ is given by

$P Q=\sqrt{\left(x_{2}-x_{1}\right)^{2}+\left(y_{2}-y_{1}\right)^{2}}$

Now,

$\begin{array}{l}{\text { Distance between }(-5,-1) \text { and }(-5,5)=\sqrt{(-5-(-5))^{2}+(5-(-1))^{2}}} \\\\ {\qquad \begin{array}{l}{=\sqrt{(-5-(-5))^{2}+(5-(-1))^{2}}} \\\\ {=\sqrt{(0)^{2}+(5+1)^{2}}=\sqrt{(6)^{2}}=6} \\\\ {=\sqrt{(-5)^{2}+(5+1)^{2}+(5-(-1))^{2}}} \\\\ {=\sqrt{(-8)^{2}+(5+1)^{2}}=\sqrt{64+36}=\sqrt{100}=10} \\\\ {=\sqrt{(3-1)^{2}+(-1-(-1))^{2}}} \\\\ {=\sqrt{(5+3)^{2}+(0)^{2}}=\sqrt{(8)^{2}}=8}\end{array}}\end{array}$
