55°75°55°15°Step-by-step explanation:
You want the measures of the numbered angles in the figure comprised of overlapping right triangles.
Complementary anglesThe acute angles in a right triangle are complementary, as are the two angles into which a right angle is divided.
∠1 +35° = 90° ⇒ ∠1 = 55°
∠3 +35° = 90° ⇒ ∠3 = 55°
Exterior angleThe angle marked 70° is exterior to the bottom right triangle, so is equal to the sum of angles 3 and 4.
∠3 +∠4 = 70°
55° +∠4 = 70° ⇒ ∠4 = 15°
Angle 2 is the other acute angle in the bottom right triangle, so ...
∠2 = 90° -∠4 = 90° -15°
∠2 = 75°

Answer:
51.0feet
Step-by-step explanation:
To get the length of the given diagonal, we will use pythagoras theorem as shown;
First we need to get the diagonal of the base;
d² = 40²+30²
d² = 1600+900
d² = 2500
d = √2500
d = 50ft
The diagonal of the base is 50ft
Get the required diagonal
Let the required diagonal be x
x² = 10²+50²
x² = 100+2500
x² = 2600
x = √2600
x = 50.99feet
Hence the distance of the red line is 51.0feet to the nearest tenth

Michelle sells umbrellas. 2 9 of her umbrellas are blue, the rest are red. 5 11 of the red umbrellas have plastic covers. What fraction of the Michelle's red umbrellas that do not have plastic covers?
Answers
Answer: 14/33
Step-by-step explanation:
Since 2/9 of the umbrella are blue, the fraction for red umbrellas will be:
= 1 - 2/9
= 7/9
Since 5/11 of the red umbrellas have plastic covers. The fraction for those without plastic covers will be:
= 1 - 5/11
= 6/11
Therefore, the fraction of Michelle's red umbrellas that do not have plastic covers will be:
= 6/11 × 7/9
= 42/99
= 14/33

A swimming pool is in the shape of a rectangular prism with a horizontal cross-section 10 feet by 20 feet. The pool is 5 feet deep and filled to
capacity. Water has a density of approximately 60 pounds per cubic foot, or 8 pounds per gallon.
What is the approximate weight of water in the pool?
Answers
Answer:
The weight of the water in the pool is approximately 60,000 lb·f
Step-by-step explanation:
The details of the swimming pool are;
The dimensions of the rectangular cross-section of the swimming pool = 10 feet × 20 feet
The depth of the pool = 5 feet
The density of the water in the pool = 60 pounds per cubic foot
From the question, we have;
The weight of the water in Pound force = W = The volume of water in the pool given in ft.³ × The density of water in the pool given in lb/ft.³ × Acceleration due to gravity, g
The volume of water in the pool = Cross-sectional area × Depth
∴ The volume of water in the pool = 10 ft. × 20 ft. × 5 ft. = 1,000 ft.³
Acceleration due to gravity, g ≈ 32.09 ft./s²
∴ W = 1,000 ft.³ × 60 lb/ft.³ × 32.09 ft./s² = 266,196.089 N
266,196.089 N ≈ 60,000 lb·f
The weight of the water in the pool ≈ 60,000 lb·f
Kayden was offered a job that paid a salary of $39, 500 in its first year. The salary
was set to increase by 2% per year every year. If Kayden worked at the job for 9 years,
what was the total amount of money earned over the 9 years, to the nearest whole
number?
Answers
Answer:
FV= $385,307.82
Step-by-step explanation:
Giving the following formula:
Annual salary (A)= $39,500
Growth rate (g)= 2% annual
Number of years (n)= 9 years
To calculate the total amount earned over 9 years, we need to use the following formula:
FV= {A*[(1+g)^n-1]}/g
A= annual deposit
FV= {39,500*[(1.02^9) - 1]} / 0.02
FV= $385,307.82
Jordan is saving to buy a computer that costs $425. So far she has saved $125, and she adds $20 to her savings each week. How many weeks must she save to be able to afford the computer?
Answers
Answer:
15 more weeks
Step-by-step explanation:
425 - 125 (what shes already saved)
300 divided by 20 (amount shes saving each week)
Result is 15, so 15 more weeks.
Hope this helped :)
If you mean how many weeks total, 125 according to the 20 dollars a week would bring it 22 weeks i think.. since the answer answer is 21.2 weeks exactly when you divide 425 by 20.

Emma eats 5 bags of chips a week. How many bags of chips does she eat (on average) a day? A month? A year?
Answers
Answer:
5/7 ; 21 ; 260
Step-by-step explanation:
Given that:
Number of bag of chip eaten in a week = 5
Therefore, on average
Number of bags eaten per day will be :
Number of days per week = 7
Number of bags eaten per day= 5 /7 = 0.714 bags
Number of bags eaten per month :
Number of days in a month = 30
Number eaten or month = 5/7 * 30 = 21.42 bags = about 21 bags
Number of bags eaten per year :
Number of days in a year = 365 days
= 5/7 * 365
= 260.71
= about 260 bags per year.

4. you try this
5. you try this
Step-by-step explanation:
Each problem follows the same approach to solve.
Setup 2 equations, one showing the total number and the other showing the total costs.
I'll work out problem 3 and you should be able to do the other two
L=the number of balls
T=the number of bats
equation 1:
L+T=100
equation 2:
L(4.50) + T(20.00) = 822
solve for T in equation 1:
T= 100-L
now substitute T in equation 2:
L(4.5) + 20(100-L) = 822.0
solve for L:
L= -1178/-15.5=76
T=100-76=24

Yoko's fish tank has 17 liters of water in it. She plans to add 5 liters per minute until the tank has at least 57 liters. What are the possible numbers of minutes Yoko could add water?
Answer:
Minutes = 8 minutes
Step-by-step explanation:
Topic: Inequality
Given:
Available Size of water = 17 liters
Increment = 5 liters/minute
Size of water needed = At least 57 liters
Putting the above together, as have
17 + 5m > 57
where m represents total minutes and > represent at least
Solving the Inequality
5m > 57 - 17
5m > 40 ------ Divide through by 5
5m/5 > 40/5
m > 8
So, Yoko will need to add water for at least 8 minutes before she fills her tank to 57 liters.
