Tina paid $6.60 for some $0.15 stamps and some $0.20 stamps. She bought 37 stamps in all. How many of each kind did she buy?
PLS HELP

Answers

Answer 1

Answer:

1 set of A= $0.15

1 set of B= $0.20

Total Stamps bought = 37

Total purchase = 37

Let X= Set A of $0.15 each

Y= Set B of $0.20 each

x+y = 37----------X=37-Y

0.15X + 0.20Y = 6.60

0.15(37-Y) + 0.20Y = 6.60

5.55- 0.15Y + 0.20Y =6.60

0.05 Y = 6.60-5. 55

Y=1.05/ 0.05= 21

X= 37-21= 16

$85000

Step-by-step explanation:

Answer: The answer is $85,000

Step-by-step explanation: Basically, you have to divide -3,400 on both sides. So 85,000 ÷ -3,400 = -25. Now, you have to substitute x, which is -25. -3,400 x -25 = 85,000. Hope this helps!! :)

Answers

Answer:

785cm³

Step-by-step explanation:

3.14×5=15.7

15.7×5=78.5

78.5×10=785

785cm³

Answer:

Volume is 785 cm^3

Step-by-step explanation:

Well first you can find the area of the base which in this case is the circle.

Follow the formula to find area of a circle

a=πr^2

We know π is 3.14 so plug in the radius which is 5

3.14*5^2=a

Solve and you’d get 78.5

Now multiply the base by the height

78.5*10= 785

A farmer sells 8.7 kilograms of pears and apples at the farmer's market. 3/4 of this weight is pears, and the rest is apples. How many kilograms of apples did she sell at the farmer's market?

Answers

Answer:

2.2 kg

Step-by-step explanation:

1000g = 1kg

8700g = 8.7kg

3/4 = 75%

8700 / 100 = 87

87 * 75 = 6525

8700 - 6525 = 2175

2.175kg or if rounded 2.2kg

Floyd decides to invest $1,000,000 in a 20-year annuity that earns 4.6% APR compounded monthly. How much money will Floyd be paid each month from this annuity?

Answers

Answer:

$6380.38

Step-by-step explanation:

Floyd will be paid $2,504,880 each month.

What is Compound Interest?

Compound interest is an interest of interest to the principal sum of a loan or deposit. The concept of compound interest is the interest adding back to the principal sum so that interest is earned during the next compounding period.

Given that Floyd invests $1,000,000 in a 20-year annuity that earns 4.6% APR compounded monthly.

A = P(1+r)ⁿ

A = 1,000,000(1+0.046/12)²⁰⁽¹²⁾

A = 2,504,880

Hence Floyd will be paid $2,504,880 each month.

Answers

Answer:

201.53[tex]m^{2}[/tex]

Step-by-step explanation:

That is a hexagonal pyramid, which means it consists of one hexagon and six triangles.

Let's first find the hexagonal base.

The formula to find the area of a hexagon is [tex]\frac{3\sqrt{3}}{2}a^{2}[/tex], where a is the length of one side of the hexagon. In this question, a = 6m

Solve that to find that the area of the hexagon is 93.53m^2.

Now, on to the triangles. The area of one triangle is the base times the height, then halved. We know that the base of the triangle is 6m as it shares the base with a side of the hexagon, and the question states that the height is also 6m.

6 * 6 = 36

36 / 2 = 18

Hence, the area of one triangle is 18m^2

However, there are six triangles - not just one!

6 * 18 = 108

Adding everything up:

93.53 + 108 = 201.53

The answer is 201.53m^2

Answers

Answer:

Area = 11 sq. units

Step-by-step explanation:

Base = 11 units

height = 2 units

Area = 1/2 × base × height

Area = 1/2 × 11 × 2

Area = 11 sq. units

11 square units is the area of the triangle , option A is correct.

What is Triangle?

A triangle is a three-sided polygon that consists of three edges and three vertices.

The formula to find area of triangle is half times of base and height

Given Base is 11 units

height is 2 units

Area = 1/2 × base × height

Plug in the values of base and height

Area = 1/2 × 11 × 2

Area = 11 sq. units

Hence, 11 square units is  the area of the triangle , option A is correct.
