It is 70° because the other triangle has the same angle and it is labeled 70° in the other triangle.
Answer: 70°
Answer:
(x,y+7)
Step-by-step explanation:
A translation means you are moving the image a certain amount of units, in this case, 7 units up. Since x values are all horizontal x does not change, but all y values will be 7 units higher.
For example (1,2) becomes (1,9).
To make it easier, you calculate the volume of the first aquarium.
1st aquarium:
V = L x W x H
V = 8 x 9 x 13
V = 72 x 13
V = 936 in.
Rate: 936 in./2 min.
Now that you've got the volume and rate of the first aquarium, you can find how many inches of the aquarium is filled within a minute, which is also known as the unit rate. To do that, you have to divide both the numerator and denominator by their least common multiple, which is 2. 936 divided by 2 is 468 and 2 divided by 2 is 1.
So the unit rate is 468 in./1 min. Now that you've got the unit rate, you can find out how long it'll take to fill the second aquarium up by finding its volume first.
2nd aquarium:
V = L x W x H
V = 21 x 29 x 30
V = 609 x 30
V 18,270 inches
Calculations:
Now, you divide 18,270 by 468 to find how many minutes it will take to fill up the second aquarium. 18,270 divided by 468 is about 39 (the answer wasn't exact, so I said "about").
2nd aquarium's rate:
18,270 in./39 min.
As a result, it'll take about 39 minutes to fill up an aquarium measuring 21 inches by 29 inches by 30 inches using the same hose. I really hope I helped and that you understood my explanation! :) If I didn't, I'm sorry. I tried. :(
Hey!
To solve x in this equation we must first add five to both sides to get

on its own.
<em>Original Equation :</em>

<em>New Equation {Added 5 to Both Sides} :</em>

Now we must square both sides of the equation.
<em>Old Equation :</em>

<em>New Equation {Changed by Squaring Both Sides} :</em>

And now we must solve the new equation.
Step 1 - Switch sides

Step 2 - Subtract x from both sides

Step 3 - Simplify

Now we need to solve the rest of the equation using the quadratic formula.

<em>So, this means that in the equation

,</em>
x = 9 <em>and </em>
x = 4.Hope this helps!
