Hello!

We could connect these two points making a right triangle with leg lengths 4 and 3. Let's use the Pythagorean Theorem to find the hypotenuse.

16+9=25

√25=5

Therefore, our answer is D) 5 miles

I hope this helps!

M over 4=8 the answer is 32 what are the steps to this equation?

harkovskaia [24]

Explanation:

4x+8=32

Isolate for x. Start by subtracting 8 from both sides of the equation.

4x+8−8=32−8

4x=24

Divide both sides of the equation by 4.

4x4=244

x=6

How do you do this problem?

Sauron [17]

Answer:

Step-by-step explanation:

Part A

If it is compounded quarterly, the interest of 1.5 must be cut into a quarter of its present size. 1.5 //4 = 0.375 % per quarter.

In addition, the number of times that payment will be received is

4 quarters * 5 years = 20 quarters.

i = principle (1 + 0.375/100) ^20

i = principle (1 + 0.00375)^20

The principle = 4000 dollars.

i = 4000 * (1.00375)^20

i = 4000 * 1.07773

i = 4310.93

So she's tied up 4000 dollars to make 300 dollars.

Part B

I can't really give you an answer to this because I don't know if the 7% is compounded and over what period of time if it is, or if they mean 7% annually. There's a lot of variation in this question. Most people don't take money out of the market, so if it compounded, the formula would be

New Principle = starting amount (1.07)^4

New Principle = 4000 * 1.07^4

New Principle = 5243.18 so she would make about 4 times as much as the 300 she makes if she puts the money in a bond.

=============

If the interest is simple interest

Gain would be 0.07 * 4000 = 280 dollars.

Over four years = 4*280 = 1120 dollars.

You are going to have to ask your teacher what is intended by this question.

Jane travels7 mph less than2 times as fast as Mike. Starting at the same point and traveling in the same direction, they are198

Sphinxa [80]

Let:

Vj = Speed of jane

Vm = Speed of mike

d = distance

t = time

Jane travels 7 mph less than 2 times as fast as Mike, therefore:

Vj = 2Vm - 7

Remeber:

distance = speed*time

Distance traveled by mike:

d=Vm*t = Vm*6

Distance traveled by jane:

d + 198 = Vj*6

where:

Vj = 2Vm - 7

d + 198 = (2Vm-7)*6

Now, let:

d=Vm*6 (1)

d + 198 = (2Vm-7)*6 (2)

Replace (1) into (2)

6Vm + 198 = 12Vm - 42

Subtract 6Vm from both sides:

6Vm + 198 - 6Vm = 12Vm - 42 - 6Vm

198 = 6Vm - 42

Add 42 to both sides:

198 + 42 = 6Vm - 42 + 42

240 = 6Vm

Divide both sides by 6:

240/6 = 6Vm/6

40 = Vm

Vm = 40mph

Replace Vm into this equation Vj = 2Vm - 7 :

Vj = 2(40) - 7 = 80 - 7 = 73mph
