Answer:c+2
Step-by-step explanation:
The circumference of a circle -
The radius is
10 in.
Answer:
l = 32.5 units, w= 27.5 units, A = 893.75 units²
Step-by-step explanation:
width is w
length is l = 5+w
P = 2( l+w) , substitute l for 5+w
P = 2(5+w+w)
P = 2(5+2w)
P = 10 +4w
P = 120
10 +4w = 120
4w = 120-10
4w = 110
w= 110/4
w= 27.5 units
l = 5+w = 5+ 27.5 = 32.5 units
A = l*w = 27.5 * 32.5 = 893.75 units ²
Answer:
A = $3094.58
General Formulas and Concepts:
<u>Pre-Algebra</u>
- Order of Operations: BPEMDAS
<u>Algebra I</u>
Simple Interest Rate Formula: A = P(1 + r)ⁿ
- A is the final amount
- P is the principal amount
- r is the rate
- n is the time (in years)
Step-by-step explanation:
<u>Step 1: Define variables</u>
A = ?
P = 3020
r = 0.05
t = 6 months = 0.5 years
<u>Step 2: Solve for </u><em><u>A</u></em>
- Substitute: A = 3020(1 + 0.05)^0.5
- Add: A = 3020(1.05)^0.5
- Evaluate: A = 3020(1.0247)
- Multiply: A = 3094.58
And we have our final answer!
Answer:
Step-by-step explanation:
A.) As the number of hours spent on homework increases, the test scores received also most likely will increase.
B.) If someone does 2 hours of homework, you just sub in 2 for x, so you should get the equation y=8(2)+40, or a score of 56.
C.) The 40 is the y intercept, which means that the student is guaranteed to get at least a 40 on a test even if they study for 0 hours.
Hope this helps :)
