Step-by-step explanation:

Answer: $52.50

Step-by-step explanation:

There is $50 in the account and it earns interest at a rate of 5% a year.

This interest is not compounded therefore it is simple interest.

To calculate amount earned with simple interest is:

= Deposit * ( 1 + rate * time)

= 50 * ( 1 + 5% * 1 year)

= $52.50

Answer:

P=75.922 ≈ 76

∘Step-by-step explanation:

What function uses the ADJACENT and the HYPOTENUSE?

SOH-CAH-TOA

cos P = adjacent/hypotenuse= 1.8/7.4

Pcos^-1 = (1.8/ 7.4)

​

P=75.922 ≈ 76

Answer: p>−4

Step-by-step explanation:

Let's solve your inequality step-by-step.

−2−7p<26

Step 1: Simplify both sides of the inequality.

−7p−2<26

Step 2: Add 2 to both sides.

−7p−2+2<26+2

−7p<28

Step 3: Divide both sides by -7.

−7p

Answer:

if it is in inequality form = x>2

if it is in interval notation = (2, infinity in math)

Answer:

Step-by-step explanation:

The system is

x+y=60 and x-y=4

If we get the difference between the two equations above we get

x+y-x+y=60-4

2y=56

y=28

Answer For The Number 22: Factors of 22 are 1, 2, 11, 22. There are 4 integers that are factors of 22. The greatest factor of 22 is 22. 3.

Answer For The Problem 2x3 (Divide it by the numbers I give you meaning divide the number two by what I give yo and the other number 3 by it.

The common factors for 2,3 are −1,1 . The numbers do not contain any common variable factors. The GCF (HCF) of the numerical factors −1,1 is 1 .The number is one.

Answer For The Problem 2x5 is also 1 so decide both 2&5 by 1 then multiply. After doing that for answers 2&3 add them. last if you then subtract 22 that might be the answer so put that & also put the answer of the greatest common factor of 22 which is 3. Make sure to include that the one where you subtracted 3 was the greatest common factor for 22.

Answer:

Stefan spent $120 originally

He made $24 dollars by selling the bicycle and helmet to Jin

Step-by-step explanation:

First, find the total cost:

127 + 17

= 144

To find the original cost, divide this by 1.2

144/1.2

= 120

So, Stefan spent $120 originally.

Now, find how much he made by subtracting 120 from 144:

144 - 120

= 24

So, he made $24 dollars by selling the bicycle and helmet to Jin.

Answer:

The variable g represents the number of gallons

Step-by-step explanation:

Given that

Issac would filled up his 20 gallon gas tank that cost would be $3.54 per gallon

5400 G represent the cost of the number of gallons of fuel

Here the variable g represent the number of gallons

So the same would be considered

Answer:

I think it may be 120 cm

Step-by-step explanation:

A F is 13 using pythagorean theorem on triangle CED and applying the hypotenuse length to A F.

ABC is similar to triangle CED and is dilated by a factor of 3  so the base is 36.

using pythagorean theorem on triangle ABC gets the hypotenuse length of 39 which can be applied to FE

add all the values together

39 + 13 + 15 + 36 +12 +5 = 120

-20 x 2 or -10 x 4 both equal -40

-2 x 3 = 6

Answer:

n = 2

Step-by-step explanation:

(6n - 7) + (8n + 2) = 23 (Combine like terms)

14n  - 5 = 23 (Add 5 from both sides)

14n = 28 (divided 14 from both sides)

n = 2

Answer:

Tank which is capable of holding 1 can fill each one of the tanks an exact number of time.

Step-by-step explanation:

Three tanks are capable of holding [tex]361,841,901[/tex]

To find which tank can be used to fill each one of them an exact number of time, find [tex]HCF(361,841,901)[/tex]

[tex]361=19^2\\841=29^2\\901=17(53)[/tex]

Therefore,

[tex]HCF(361,841,901)=1[/tex]

So, tank which is capable of holding 1 can fill each one of the tanks an exact number of time.
