Help please I added the number line.

Answers

The answer is H because if you use a calculator and do 5.75 - 3.50 you would get 2.25 then count out how many 0.25 would make 2.25

Answer:H

Step-by-step explanation:

Because 0.25 x 9 will give you 2.25. Then add that to the original number; $3.50 + $2.25 = $5.75. Hope this helps :)

State whether the number is a solution to the giving inequality.

n>9/16;7/12

Answers

yes it is because you find the LCM which is 48 so then you convert those 2 fractions to have a denominator of 48 so 7/12 becomes 28/48. next you change 9/16 which becomes 27/48. now your equation would be 28/48>27/28

Can the perimeter be larger than the area?

Answers

Answer:

YES

Step-by-step explanation:

SOMETIMES

Answer:

The area can be smaller or larger than the perimeter depending on the shape.

Step by Step Explanation:

You can divide your diagram into one-unit (feet, cm, miles) segments vertically and horizontally if you want to visualize how the area measurement will look. Multiply the length of your rectangle by the width.

Given that the area of a rectangle is 4 2/3 in and the length 3 1/2 in find the width

Answers

Area = l x b = 4 2/3 x 3 1/2
= 14 /3 x 7/2
= 49/3
= 16 1/3

Ans is 16 1/3

5 The smallest angle of a triangle, in degrees, is p.
The second angle is 4 times the smallest angle.
The third angle is 5 times the smallest angle.
a Write an equation for the angles in the triangle in terms of p.

b Find the size of the largest angle in the triangle.

b in paticular

Answers

Answer: b = 90

Step-by-step explanation:

Full triangle is 180

5 + 4 = 9 + 1 (the smallest angle)

180 ÷ 10 = 18

First and smallest angle is 18

p= 18

Second angle is 72

18 × 4 = 72

Thrid angle is 90

18 × 5 = 90

b = 90

18 + 72 = 90 + 90 = 180

The value of a share of stock decreases in value at a rate of $1.40 per hour during the first 3.5 hours of trading. Enter and solve an equation to find the decrease in the value of the share of stock during that time. Let x represent the decrease in value of the share of stock during 3.5 hours.

The equation to find the decrease in the value of the share of stock is x / _____ = _______

The decrease in value of the share of stock during 3.5 hours was $________

Answers

Answer:

x/3.5h = -$1.4

So, x = -$1.4 * 3.5h

= -$4.9

Step-by-step explanation:

Since your losing $1.4 every hour, the 1.4 is supposed to negative.

Also, since your losing that amount of money for 3.5 hours, we are trying to find the total of how much money is lost in the 3.5 hours. To do this, we have to do x/3.5h = -$1.4. But since you can't do x/3.5, we have to do inverse operation. When you divide 3.5 hours to the other side of the equation it becomes multiplication. So you do -$1.4 times 3.5 hours

and get -$4.9.

2. Apples cost more per pound.

Step-by-step explanation:

1. Brian reads 2/15 in 20 minutes, like we were told. It's easy to determine how much of his book he can read within an hour, by using the ratio 1/15:10. There's clearly 1/15 in 10 minutes, 2/15 in 20, 3/15 in 30, and so on. This would result in him reading 6/15's of his book in an hour.

Peaches

0.6÷8/5 converts to .6 × 5/8. The result is .375.

Apples

1.75 ÷7/2 converts to 1.75×2/7. The result of this equation is .5, so therefore, the apples cost more per pound.

8/15 because 2/15 *3 is 6/15 + 2 is 8 and you multiply by 3 because 60/20=3
