95°
50°
27°

Answers

If is an acute triangle, all the angles should be acute angles.
180-38=142°
142-69=73°
So your answer is 69°, lovely~

One of the angles as your answer is 69 degrees

Arezo borrowed $2,500 from her grandfather. This graph shows the balance remaining on Arezo’s debt after she makes each payment. Using this graph, how much will she owe after 4 payments?

Answers

Answer:

She will owe $500 after 4 payments.

Step-by-step explanation:

With the help of graph

Number of payments (x) Balance remaining(y)

0 2500

1 2000

2 1500

Since it is linear function .

So, we will use two point slope form to find the equation for the given situation.

$y-y_1=(y_2-y_1)/(x_2-x_1)(x-x_1)$ ----A

$(x_1,y_1)=(0,2500)$

$(x_2,y_2)=(1,2000)$

Substitute the values in A

$y-2500=(2000-2500)/(1-0)(x-0)$

$y-2500=-500x$

$y=-500x+2500$

Where x is the number of payments

y is the remaining payment

This equation represents the given situation.

So, to find the amount remaining after 4 payments .Substitute x =4

$y=-500(4)+2500$

$y=-2000+2500$

$y=500$

Hence she will owe $500 after 4 payments.

Answer:

She will owe $500

Jared has one pizza that has 12 slices. he wants to share his pizza with his two brothers. how many slices will each boy have if they each have a equal amount

Answers

each brother should get 4 slices. 12 slices divided by 3 brothers equals 4 slices each.

Put simply, the question is just asking you to divide 12 by 3. Therefore, each brother gets 4 slices as 12 ÷ 3 = 4.

Today, the Great Pyramid at Giza near Cairo, Egypt stands 137 meters tall, coming to a point.Its base is a square with each side measuring 230 meters wide. What is the slope of the pyramid?

Answers

Hope you can see the picture and understand the drawings.

It can seem complex at first but you just have to think it through.

I use pythagoras' theorem to find the diagonal of the base square and then use that information along with the height with the aid of that ever so handy pythagoras' theorem to find the length of the slope.

A cold water pipe can fill a swimming pool in 4 hours, and a hot water pipe in 6 hours. If cold water pipe is turned on and hot water pipe is turned on 3 hours later then how long will it take them to fill the pool together?

Answers

If cold water pipe is turned on and hot water pipe is turned on 3 hours later then it will take 36 minutes (or 0.6 hr) to them to fill the pool together.

Step-by-step explanation:

Given :

Cold water pipe can fill a swimming pool in 4 hours, and a hot water pipe in 6 hours.

Solution :

Let's say the swimming pool is x gallons.

The flow rate of the cold water pipe is,

$\rm (x)/(4)\;gal/hr$

The flow rate of the hot water pipe is,

$\rm (x)/(6)\;gal/hr$

If the cold water pipe is turned on for three hours, the volume of water is:

$\rm (x)/(4) gal/hr* 3 hr = (3x)/(4) \;gal$

The time to fill the rest of the pool with both the cold and hot water pipes is,

$\rm ((x)/(4))/((x)/(4)+(x)/(6))= (1)/(4)* (24)/(10)\;hr$

= 0.6 hr

If cold water pipe is turned on and hot water pipe is turned on 3 hours later then it will take 36 minutes (or 0.6 hr) to them to fill the pool together.

Answer:

0.6 hours

Step-by-step explanation:

Let's say the swimming pool is 12,000 gallons.

The flow rate of the cold water pipe is:

12000 gal / 4 hr = 3000 gal/hr

The flow rate of the hot water pipe is:

12000 gal / 6 hr = 2000 gal/hr

If the cold water pipe is turned on for three hours, the volume of water is:

3000 gal/hr × 3 hr = 9000 gal
