The answer is 2,000,000,000,000
Answer:
<h2>a = 400/21, b = 580/21</h2>
Step-by-step explanation:
Small triangles are similar. Therefore, the sides are proportional
<em>cross multiply</em>
<em>divide both sides by 21</em>

For b, we can use the Pythagorean theorem:

Answer:
y = 1/2x + 2
Explanation:
The line intercepts the y-axis at 2, so that would be "b" using the slope-intercept formula y = mx + b. (I won't explain the slope as I am tired now.)
<span>seventy two hundredths</span> = 0.72.
Decrease = Subtraction.
Two Tenths = 0.2
So:
0.72 - 0.2
0.72 - 0.2 = 0.52
So, This Expression Is Equal To 0.52
Answer:
A gum and a cracker
Step-by-step explanation:
She receive 3 of the same type of coin as change => the leftover change should be divisible by 3
If she buy a gum and a cracker, she would be leftover with 100 - (50+35) = 15 cents.
And that is divisible by 3, so we can conclude she bought a gum and a cracker.
