Answer 2

Answer:

1. correct

2. not correct

3.correct

4.correct

5. not correct

6. correct

Step-by-step explanation:

P(parenthesis) E(exponents) M(multiplication) D(division) A(addition) S(subtraction)

You first solve what is in the parenthesis (if there is any) than make your way down this list IN ORDER until you hit subtraction.

1.

[tex](8+7)/3=5\\\\(15)/3=5\\5=5[/tex]

2.

(4 × 5) − 3 = 8

Parenthesis first

(20)-3=8

subtract

17=8

3.

(4 × 5) − 3 = 17

Do what is in parenthesis first

(20)-3=17

subtract

17=17

4.

14 − 7 × 2 = 0

Multiply 7*2 first

14-14=0

subtract

0=0

5.

14 − 7 × 2 = 14

Multiply 7*2 first

14-14=14

subtract

0=14

6.

12 + (7 + 9) = 28

Parenthesis first

12+(16)=28

Add

28=28

(d) Which solid figures can the stairs be broken into? What are the dimensions of each solid figure?
(e) How much concrete will be needed to form the stairs?

Answers

D. The solid figure can be broken into rectangles, it’s dimensions would be 24mx0.4m
E. To find how much concrete is needed you have to...
multiply LxWxH
So multiply 1.8x1.2x2.4=5.184
Then divide 1.8 by 3= 0.6
Each small rectangle is 0.6 m in height
5.184-1.8=3.384

Truman is buying a teddy bear and flowers for his girIfriend. Flowers Galore charges $13 for the teddy bear and $0.75 per flower. Famous Florist charges $9 for the teddy bear and $1.25 per flower. Which inequality represents the number of flowers, f, Truman would need to buy to make Flowers Galore the cheaper option?

Answers

the answers is either f < 2 or f > 2

The inequality that would make Flowers Galore the cheaper option is 13 + 0.75f < 9 + 1.25f

How to determine the inequality?

At Flowers Galore, we have:

Teddy bear = $13

Flower = $0.75

At Famous Florist, we have:

Teddy bear = $9

Flower = $1.25

So, the expressions are:

Flowers Galore: 13 + 0.75f

Famous Florist: 9 + 1.25f

When Flowers Galore is the cheaper option, we have:

13 + 0.75f < 9 + 1.25f

Hence, the inequality that would make Flowers Galore the cheaper option is 13 + 0.75f < 9 + 1.25f
