You earn $44.55 in 9 hours. Your friend earns $51.00 in 12 hours. How much do you AND your friend earn in 20 hours? HINT- You need to calculate how much you both make in 1 hour first! 1 point
Answer:
I earn $99. my friend earns $85. We both earn $184
Step-by-step explanation:
Steps
Find the amount earned per hour for each friend multiply the value gotten by 20 hours Add the amountAmount i earn per hour = 44.55 / 9 = $4.95
Amount my friend earns = 51 /12 = $4.25
Amount earned in 20 hours
4.95 x 20 = 99
4.25 x 20 = 85

How do I solve this?
-1/3+y=1
Answer:
y=-3
Step-by-step explanation:
.....................
Answer to equation:
y = 1 1/3
Step-by-step explanation:
for this problem we see that we are starting below 0 and going up to one, all we have to do is solve for the distance between the two numbers, as shown
(-1/3) + 1/3 = 0
0 + 1 = 1
now to simplify, we just add the total amount of change between the two numbers
1/3 + 1 = 1 1/3
NOTE: this can be done by just adding the absolute value of each number if one is a negative number and one is a positive number, wich is basically what i did
-1/3 = |1/3|
1 = |1|
|1/3| + |1| = |1 1/3| or total amount of change
but if you are working with two positive or two negative numbers, then subtract the lesser of the two absolute values as so
-2 + x = -5
-2 = |2|
-5 = |5|
|5| - |2| = |3|
3 = amount of change
3 = x
-2 + -3 = -5

When you became a manager, your 49478 annual salary increased 22%. You found the new job too stressful and requested a return to your original job. You
resumed your former duties at a 23% reduction in salary. How much are you making at your old job after the transfer and return? Estimate your answer to 0
places after the decimal.
Answer:
$46,479
Step-by-step explanation:
22% of 49478 is 10885.
You add them.
60363.
Then take 23% of that which is 13883.
Then subtract them.

What is the area of this figure?
(Use = 3.14 and round to two decimal places.)
0.1 cm
Answer:
the area of above figure is 0.31 cm^2
Answer:
A ≈ 0.03 cm²
Step-by-step explanation:
Area of a circle = πr²,
where π (pi) ≈ 3.14 or 22/7 as a close fraction is the ratio (factor) between the circumference and the diameter (2 times / twice the radius),
and r² is the radius squared or multiplied by itself once.
Given that the radius is 0.1 cm in this situation,
the area of this circle is as follows:
A = πr² → A = π (0.1)² cm² → π(0.01) cm² → 0.01π cm² →
(1/100)(π) cm² → π / 100 cm² → 3.14 / 100 cm² →
0.0314 cm² ≈ 0.03 cm²
1. Consider the circle to the right,
Part A: Determine mzSBE.
Part B: Determine mob.
S
52
B
Answer:
m∠SBE = 26°, [tex]m\hat O B[/tex] = 126°
Step-by-step explanation:
The arc of a circle is a portion of the circumference of the circle. For a circle, the degree measure of an arc is equal to the measure of the central angle that intercepts the arc.
Central angle is an angle whose vertex is on the center of the circle and endpoints on the circumference of the circle. If the endpoints of the central angle are are also the endpoints for the angle's intercepted arc, then both angles are congruent.
Also, the angle at the center is twice the angle at the circumference.
Angle at center = [tex]m\hat S E[/tex] = 52° (central angle is congruent with angle that intercept the arc)
2 * m∠SBE = central angle (angle at the center is twice the angle at the circumference)
2 * m∠SBE = 52
m∠SBE = 26°
2 * m∠BEO = central angle (angle at the center is twice the angle at the circumference)
2 * 63 = central angle
central angle = 126°
Angle at center = [tex]m\hat O B[/tex] = 126° (central angle is congruent with angle that intercept the arc)
The radius of a circle is 13 feet. What is the circle's area?
Use 3.14 for pi.pleeeaaase heelpp!!
Answer:
answer is 530.66 hope this helps!
13×13=169
169×3.14=530.66
Answer:
I don't know if this is the answer but I got 530.66
Step-by-step explanation: the formula is A=pi r squared
you multiply 13 twice because in the formula you have to square the radius then you have to multiply what you get in this case 169 then you multiply it by pi which is 3.14 by 169 and you get 530.66 hopefully it is right let me know and if so brainliest please:)

-3|x|+2x-1 if x=-5
i need help with this or else i will not get my computer
Answer:
-26
Step-by-step explanation:
Hello There!
For this problem all we have to do is plug in -5 into x and calculate the value
so..
-3|-5|+2(-5)-1
so first things first | | means absolute value
The absolute values of -5 is 5 so the equation would be
-3(5) + 2(-5) - 1
-3*5=-15
2*-5=-10
-15-10=-25
-25-1=-26
so the answer would be -26

The lengths of the sides of a triangle are given below. Classify the triangle as acute, obtuse, or right.
13, 14, 17
A. Acute Triangle
B. Obtuse Triangle
C. Right Triangle
Answer:
A. Acute TriangleStep-by-step explanation:
Lets verify with Pythagorean:
17² = 28913² + 14² = 169 + 196 = 365289 < 365The angle opposite to a greater side is less than 90° and the sum of the squares are close.
It means all three angles are less than 90°.
With this the triangle is acute.
Correct choice is A.
