CAN SOMEONE ANSWER THIS PLEASEMargie bought 1 1/2
pounds of tomatoes for $2.00 per pound,
1/4 pound of onions for $1.60 per pound, and 1 pound of apples for $1.65 per pound. How much did she pay for her total purchase?

Answers

Answer 1
Answer:

Answer:

She spent $5.05 for her total purchase.

Step-by-step explanation:

First, you should convert the fractions into decimals to make it easier, which would make it, 1.5, .25, 1.

Second, multiply 1.5 by 2 because there are 1.5 pounds which are payed for $2.00. Do the others fractions corresponding with the number of pounds and the cost this same way. 1.5 multiplied by 2 is 3. .25 multiplied by 1.60 is 0.4, 1 multiplied by 1.65 is 1.65.

Lastly, Add it all up, 3+0.4+1.65=5.05

WHAT is the answers to 2a 2b and 2c ?

Answers

a). The shape has 5 sides. The inside angles of every 5-sided shape (pentagon) add up to 540 degrees. The 3 angles given add up to (110 + 109 + 100) = 319 . The two leftover angles add up to (540 - 319) = 221 degrees. They're not equal, so we can't tell how the 221 breaks down between them. b). The shape has 4 sides. The inside angles of every 4-sided shape add up to 360 degrees. The 3 angles given add up to (85+ 92 + 93) = 270 degrees. The fourth angle is (360 - 270) = 90 degrees, even though it doesn't look like it. c). The shape has 6 sides. The inside angles of every 6-sided shape add up to 720 degrees. The 4 angles given add up to (120 + 110 + 105 + 110) = 445 degrees. The two leftover angles add up to (720 - 445) = 275 degrees. They're not equal, so we can't tell how the 275 breaks down between them.

A book sold 38.400 copies in its first month of release. Suppose this represents 7.3% of the number of copies sold todate. How many copies have been sold to date?Round your answer to the nearest whole number

Answers

Since 38400 is 7.3% of the number of copies, then we can calculate the total number of copies with:

38400*100/7.3 = 526027.39. Rounded to the nearest whole number we have: 526027

The answer is 526027

2. Which is larger?The common ratio, r , in a geometric sequence whose second term is
24 and whose fifth term is 1536
or
The common difference, d , in an arithmetic sequence whose fourth
term is 16 and whose seventh term is 31.

Answers

Answer:

The common difference d is larger than the common ratio r

Step-by-step explanation:

  • The common difference in the arithmetic sequence  d=u_(n)-u_(n-1)
  • The nth term in the arithmetic sequence is a_(n)=a+(n-1)d , where a is the first term
  • The common ratio in the geometric sequence r=(u_(n))/(u_(n-1))
  • The nth term in the geometric sequence is a_(n)=a(r)^(n-1) , where a is the first term

Geometric sequence

∵ The second term is 24

∴ u_(2) = 24

∵ u_(2)=a(r)^(2-1)=ar

- Equate it by its value

∴ ar = 24 ⇒ (1)

∵ The fifth term is 1536

∴  u_(5) = 1536

∵ u_(5)=a(r)^(5-1)=ar^(4)

- Equate it by its value

∴ ar^(4) = 1536 ⇒ (2)

Divide (2) by (1)

∴ (ar^(4))/(ar)=(1536)/(24)

- Divide up and down by ar

∴ r³ = 64

- Take ∛  for both sides

∴ r = 4

Arithmetic sequence

∵ The fourth term is 16

∴ u_(4) = 16

∵ u_(4) = a + (4 - 1)d

∴ u_(4) = a + 3 d

- Equate it by its value

∴ a + 3d = 16 ⇒ (1)

∵ The seventh term is 31

∴ u_(7) = 31

∵ u_(7) = a + (7 - 1)d

∴ u_(7) = a + 6 d

- Equate it by its value

∴ a + 6 d = 31 ⇒ (2)

Subtract equation (1) from equation (2) to eliminate a and find d

∵ (a - a) + (6 d - 3 d) = (31 - 16)

∴ 3 d = 15

- Divide both sides by 3

∴ d = 5

∵ r = 4 and d = 5

∴ d > r

∴ The common difference d is larger than the common ratio r

Amelia has a triangular kite with an area of 30 square inches and a height of 6 inches. How long is the base of the kite?

Answers

Area of triangle = 0.5 * base * height 
30 = 0.5 * 6 * base 
30 = 3 * base 
so , base = 10 inch 

Answer:

Draw a vertical line to break the kite into two equal triangles with a base of 36 and a height of 15. Use the formula A = 1

2

bh to find the area of each. The sum of the areas is the area of the kite.
