Answer 1

Answer:

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 angles

The 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 angle

The 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°

To find the y- intercept , substitute x = 0 into f(x), that is

f(0) = 3 × [tex]4^{0}[/tex] [ note [tex]4^{0}[/tex] = 1 ]

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.

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

priya says that 1/3 x 1/3 x 1/3 x 1/3 = 4/3. do you agree with priya? explain or show your reasoning

Answers

No, priya is wrong. Multiplying a number by one is essentially multiplying it by nothing so by multiplying 1•1•1•1 we are multiplying one by itself so it is just 1 and since we are multiplying, we must multiply the denominators as well which is just 3^4 which is 81 so that leaves your answer being 1/81.

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

I'll let you know if problems 4 and 5 are correct

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.

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.

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

Answers

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
