alan would take 5 hours to build the wall of a house, and gavin would take 7 hours to build it alone. when they work together, they talk a lot, and their combined output decreases by 26 bricks per hour. working together, they build the wall in 4 hours. how many bricks are in the wall?
Answer:
96 bricks
Step-by-step explanation:
Alan does 1/5 of the job in an hour. Gavin does 1/7 of the job in an hour
Together, 12/35 of the job should be done in an hour. In [tex]2 \frac{11}{12}[/tex] hours, the work should be done.
rate at 4 hours=[tex]2 \frac{11}{12}[/tex]*(normal speed-26)
To clarify, x=the normal rate
4 hours(normal rate-26)=[tex]2 \frac{11}{12}[/tex](normal rate)
4(x-26)=[tex]2 \frac{11}{12}[/tex]x
x=96

Answer:
The answer is 23 because they have to add up to 90-kai :)
Step-by-step explanation:
So, ∠a + ∠b = 90°
67° + ∠b = 90°
∠b = 90° - 67°
∠b = 23°
Answer:
The measure of ∠b is 23°.
Step-by-step explanation:
Complementary angles are angles that add together to always be 90°. The problem gives us this information at the start:
∠a + ∠b = 90°
∠a = 67°
You can apply this information to the equation by getting the problem of:
67° + ∠b = 90°
To solve this equation you simply rearrange the terms, and subtract 67 from 90:
90° - 67° = ∠b
After rearranging the terms and subtracting 67 from 90 you are left with the following result:
∠b = 23°
Jake had a doctor's appointment at 2:30 p.m. It takes 53 minutes to drive to the doctor's office from his work. What time does he need to leave work if he wants to arrive by 2:20 p.m.?
Hii :)
Lets solve for x (x being what time jake will leave)
First, what do we know?
We know..
Needs to arrive by 2:20pm53 minutes to get there2:30-53=1:37
So jake should leave around 1:00pm-1:30pm
2:30-1:30=1:00

C = (-4,5) D = (-2,3)
11) 8.426
10) 3, 4, 5
level 3-4) 24
Step-by-step explanation:
11) 7^2 + 11^2 = c^2
49 + 22 = c^2
√71 = √c^2
c = 8.426
10) 3, 4, 5 is a special right triangle but
3^2 + 4^2 = 5^2
25 = 25
level 3-4)
7^2 + h^2 = 25^2
49 + h^2 = 625
√h^2 = √576
h = 24

What is the volume of a hemisphere with a diameter of 7.6 m, rounded to the nearest tenth of a cubic meter?
Answer:
114.9 meter
Step-by-step explanation:
v=(2/3)πr^3
diameter=2r
r=7.6/2
r=3.8
(2/3)π* (3.8)^3
~36.58π meter
if the teacher wants you to use 3.14 as π (like instead of writing the symbol of π), then 36.58*3.14=114.9 meter
