Answer: Let the integers be x, x+1, and x+2

3(x+x+1)=13+4(x+2)

3(2x+1)=13+4x+8

6x+3=4x+21

2x=18

x=9

the integers are 9,10,11

3(x+x+1)=13+4(x+2)

3(2x+1)=13+4x+8

6x+3=4x+21

2x=18

x=9

the integers are 9,10,11

Mr.Rice needs to replace the 166.25 ft of edging on the flower beds in his backyard.The edging is sold in lengths of 19 ft each.How many lengths of edging will mr mr.Rice need to purchase?

Mr Rice will purchase 8.75 ft of edging

- Total length of edging on the flower beds = 166.25 ft
- Total length of an edging being sold = 19 ft
- The lengths of edging Mr rice will need to purchase = Y

if we derive equation for this question, then we have:

166.25 = 19Y

Y=

Y= 8.75

You can also solve it quickly by following this step:To determine the lengths of edging Mr Rice will need to purchase, the total length of edging on the flower beds (166.25) will be divided by the total length of an edging being sold (19) i.e. 166.25 ÷ 19

= 166.25 ÷ 19

=

= 8.75

Therefore, the total length of edging Mr Rice will need to purchase is 9 ft.

The above mathematical expression is a number problem, and was solved with the aid of division.

The term, division, is a basic arithmetic operation which deals with splitting or dividing two or more numerical values into different equal part.

In this case, it could be observed that the significant numbers that were divided are 166.25 and 19, resulting to 8.75. It is also a function of BODMAS (which is an order of operations).

Find the exact value of cos a, given that sin a= 8/11 and a is in quadrant I.

cos a= ?

(Simplify your answer. Type an exact answer, using radicals as needed.)

Answer:

cos(a) = (√57)/11

Step-by-step explanation:

cos(a) = √(1 -sin(a)²) = √(1 -(8/11)²) = √(57/121)

cos(a) = (√57)/11

A scarf is a triangle with two perpendicular sides that are the same length which two terms describe a triangular scarf

Answer:

A triangular scarf is an isosceles right triangle.

Step-by-step explanation:

Given: A scarf is a triangle with two perpendicular sides that are the same length.

We have to name which two terms describe a triangular scarf.

Isosceles triangle is a triangle with length of two of its sides equal.

Right angled triangle is a triangle in which one angle is a right angle.

Given :

The two sides of scarf are perpendicular to each other.

Thus, the angle formed between them is 90°. Hence, right angled triangle.

Also, length of two sides are same, Hence isosceles triangle.

Thus,a triangular scarf is an isosceles right triangle.

the density of pure gold 1,204 pounds per cubic foot? how many cubic feet is 481.6lbs of pure gold?

Answer:

Volume of Gold = 0.4 cubic feet.

Step-by-step explanation:

First we have to make sure the units are same as the units the answer is required in.

Answer should be given in cubic feet.

Density is given in pounds per cubic foot. And Mass is given in pounds. So units are in order. Therefore, we can go ahead with the calculation.

The Density of Gold = [Mass of Gold/Volume of Gold]

By substituting values,

ponds per cubic foot = [ pounds / Volume of gold]

Making Volume of God the subject of the equation,

Volume of Gold = [ pounds / tex]1204[/tex] ponds per cubic foot ]

Volume of Gold = 0.4 cubic feet.
