Answer: B

Step-by-step explanation: Took K12 quiz

$2571.67 is the maturity value of the loan of $2500.

Simple interest is an interest which is only based on principal amount, it does not imply on yearly interest.

Given that,

The principal amount of loan P = $2500

The rate of interest r = 4.3%

Time duration t = 8 months

To find the maturity value of loan,

Find interest by using formula,

I = P x r x t / 100

I = 2500 x 4.3 x 8 / 100 x 12

i = 200 x 4.3 / 12

I = 860 / 12

I = 71.666

or I = 71.67

The total amount = 2500 + 71.67 = $2571.67

The amount on maturity of loan is $2571.67.

Answer:

Step-by-step explanation:

The relations that you need to know to solve this are ...

__

The angle marked x° and the one marked 100° are vertical angles, so have the same measure:

  x° = 100°

__

The angle marked y° is supplementary to the one marked x°, so its value is ...

  y° = 180° -100° = 80°

__

The two angles marked z° and (z+10)° are also supplementary, so ...

  z° +z° +10° = 180°

  2z° = 170°

  z° = 85°

-11/40

Step-by-step explanation:

-2/5+1/8=?

Turn the fractions into the same denominators:

-2/5 x 8/8= -16/40

1/8x 5/5= 5/40

-16/40+5/40=

now just add the numerators

Answer:

A = 56 in²

Step-by-step explanation:

the area (A) of a trapezoid is calculated as

A = [tex]\frac{1}{2}[/tex] h (b₁ + b₂ )

h is the perpendicular height between bases and b₁, b₂ the bases

here h = 7 , b₁ = 10 , b₂ = 6 , then

A = [tex]\frac{1}{2}[/tex] × 7 × (10 + 6) = 3.5 × 16 = 56 in²

Answer:

54 kilometers per hour

step-by-step explanation:

according to rules:

1 km = 1000 meter

which means that 1 meter = 1/1000 km

1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]

which means that 1 second = 1/3600 hour

therefore, 1 kilometer/hour = (1/1000)/(1/3600)=3600/1000=18/5=3.6 kilometer/hour

thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

15 meter/second= 15*3.6=54 kilometer/hour which is the required answer.

Answer:

5304 people

Step-by-step explanation:

So, we have a population of 5000 people and it grows 3% per year. This problem wants us to find how much it will grow to at the end of 2 years.

With this, we have values that follow:

The formula: f(t) = a(1 + r)^t

a = 5000

r = 0.03

t = 2

Plugging it the values in the formula,

f(2) = 5000(1 + 0.03)^2

     = 5000(1.03)^2

     = 5304.5

Since there can't be a half person, we will have to reduce it down to 5304

f(2) = 5304

Answer:

William has 24 cans of fruit and 60 cans of vegetables that he will be putting into bags for a food drive.

Factor number 24 and 60:

Find the greatest common factor

Hence, the greatest number of bags William can make is 12.

Each of these bags will have  cans of fruit and  cans of vegetables.

If he made fewer bags, 6 bags, each of these bags will have  cans of fruit and  cans of vegetables.

If he made fewer bags, 4 bags, each of these bags will have  cans of fruit and  cans of vegetables.

If he made fewer bags, 3 bags, each of these bags will have  cans of fruit and  cans of vegetables.

If he made fewer bags, 2 bags, each of these bags will have  cans of fruit and  cans of vegetables.
