If there is 4 apple trees for every three pear trees but for every 2 avocado trees there is 5 pear trees she is planning to plan

olasank [31]

Answer:

Step-by-step explanation:

You need to think of it as an equation system.

First of all, let's call A the apple trees, P the pear trees and V the avocado's trees.

As for every 3 pear trees we have 4 apple trees, it can be written as:

4A = 3P

Then, we can clear the pears dividing both sides by 3:

4A/3 = 3P/3

(4/3)A = P

This is, we have one pear tree for every 4/3 apple trees.

Then we go to the other relation. For every 5 pears trees there are two avocados trees:

2V = 5P

As we want the ratio of avocados to apples we can replace the pear trees by it's expression depending on A:

2V = 5 ((4/3)A)

2V = (20/3) A

Multiplying both sides by 9 we make appear our 18 avocados trees:

2V *9 =( 20/3) A * 9

18 V = 60 A

So, for 18 avocados trees we have 60 apple trees.

ExtremeBDS [4]

Prime factor is a factor that is a prime number.
Prime factors of :
8 : 2 × 2 × 2. Also can be written as
${2}^{3}$
12 : 2 × 2 × 3. Also can be written as
${2}^{2} \times 3$

20 : 2 × 2 × 5. Also can be written as
${2}^{2} \times 5$

30 : 2 × 3 × 5

56 : 2 × 2 × 2 ×7. Also can be written as
${2}^{3} \times 7$

70 : 2 × 5 × 7

You can find all of them by using Factor Tree [ as shown in the picture] or Dividing by prime numbers.

Mary bought these art supplies: 4 paint brushes @ $1.29 each, 6 dowel rods @ $1.49 each, a jar of paste @ $1.25, and 2 canvases

Sophie [7]

Answer:

Option (1) is correct

The amount she receives back from $40 is $12.65

Step-by-step explanation:

Given: Mary bought the art supplies.

4 paint brushes @ $1.29 each, 6 dowel rods @ $1.49 each, a jar of paste @ $1.25, and 2 canvases @ $6.00 each.

We have to find the change she get from $40.

We first find the total cost of the art supplies.

Since, she brought 4 paint brushes @ $1.29 each,

Thus, cost of 4 paint brush is 1.29 × 4 = $5.16

Also, 6 dowel rods @ $1.49 each,

Thus, cost of 6 dowel rods is 1.49 × 6 = $8.94

Thus, cost of 1 jar of paste is $1.25

and 2 canvases @ $6.00 each

Thus, cost of 2 canvases is $12.00

Thus, total cost of art supplies = 5.16 + 8.94 + 1.25 + 12 =$27.35

Thus, amount she receives back from $40 is $40 - $12.35 = $12.65
