Answer:
x+63 = 90
x = 27
Step-by-step explanation:
The two angles are complementary, so they add to 90 degrees
x+63 = 90
Subtract 63 from each side
x+63-63 = 90-63
x = 27
<span>When
a data value is converted to a standardized scale representing the
number of standard deviations the data value lies from the mean, we
call the new value a z-score.
A z-score is used to indicate how many standard deviation a value is from the mean.

Step-by-step explanation:
<u>Step 1: Define</u>
35 + 0.8x = 43 - 7x
<u>Step 2: Solve for </u><em><u>x</u></em>
- [Addition Property of Equality] Add 7x on both sides: 35 + 7.8x = 43
- [Subtraction Property of Equality] Subtract 35 on both sides: 7.8x = 8
- [Division Property of Equality] Divide 7.8 on both sides: x = 1.02564
The answer is <span>2.5 × 10⁻⁹ × 1.5 × 10³ = 3.75 × 10⁻⁶ </span>
Ok so, here goes:
simple interest: r- rate, A- amount in the end, t- time, P- principal
<span>r = (1/t)(A/P - 1)
</span>Putting in our numbers
r = (1/4)((21236/5309) - 1) = 0.75
r = 0.75
Converting r decimal to R a percentage
R = 0.75 * 100 = 75%/year
The interest rate required to get a total amount, principal plus interest, of $21,236.00 from simple interest on a principal of $5,309.00 over 4 years is 75% per year.
