Answer:
The dilation is an enlargement by 3
Step-by-step explanation:
I took geometry lasy yr
1. 78 = 0.15x
78 / 0.15 = x
520 = x.....so 78 is 15% of 520
2. | 3x - 2 | = 8 | x + 1 | = 1
3x - 2 = 8 -(3x - 2) = 8 x + 1 = 1 -(x + 1) = 1
3x = 8 + 2 -3x + 2 = 8 x = 1 - 1 -x - 1 = 1
3x = 10 -3x = 6 x = 0 -x = 2
x = 10/3 x = -2 x = -2
ur answer is : x = -2
3. 3y - 4x + 5 = 0
3y = 4x - 5
y = 4/3x - 5/3
slope = 4/3
Hey there! I'm happy to help!
To find the volume of a cone, we multiply the base by the height and then divide by three.
First, we find the area of the base, which is a circle. To find a circle, you square the radius and then multiply by pi (or 3.14 in our case).
Radius is half of the diameter.
3/2=1.5
We square this.
1.5²=2.25
We multiply by 3.14
2.25×3.14=7.065
Now, we multiply this base area by the height.
7.065×7=49.455
We divide by 3.
49.455/3=16.485
Therefore, if we round this, our answer is 16.49 in³.
Now you can find the volume of a cone! Have a wonderful day! :D

Answer:
$2
Step by Step:
Four quarters is one dollar
Four quarters is 8 pennies
Multiply 8 by 25 (25 being the value of the quarters)
<em>2</em><em>5</em><em> </em><em>cents </em><em>is </em><em>times </em><em>four </em><em>is </em><em>one </em><em>dollar </em>
<em>.</em><em>2</em><em>5</em><em>x</em><em>4</em><em>=</em><em>1</em><em>,</em><em> </em><em>2</em><em>5</em><em>x</em><em>4</em><em>=</em><em>1</em><em>0</em><em>0</em><em>,</em><em> </em><em>1</em><em>0</em><em>0</em><em>x</em><em>.</em><em>2</em><em>5</em><em>=</em><em>2</em><em>5</em>
<em>2</em><em>x</em><em>4</em><em>=</em><em>8</em><em> </em><em>8</em><em>x</em><em>2</em><em>5</em><em>=</em><em>2</em><em>0</em><em>0</em>
