I need help understanding the area and perimeter of the circled shapes and help answering them. **This is a homework I need help with** I answered the other uncircled questions unvirtually but need help with circled ones.

Answers

Answer:

See below.

Step-by-step explanation:

1)

Triangle

Perimeter = sum of lengths of the 3 sides

Area = base * height/2

Perimeter = 9 m + 10 m + 11 m = 30 m

Area = 10 m * 8 m /2 = 40 m^2

5)

Parallelogram

Perimeter = sum of lengths of 4 sides.

Hint: opposite side have equal lengths

Area = base * altitude

Perimeter = 9 m + 9 m + 7 m + 7 m = 32 m

Area = 9 m * 6 = 54 m^2

3. Multiply within ratios to determine each value of z.
a) 4:8 = 3:2 b) 5:2 = 6:18 c) z: 14 = 10:20
d) 3:21 = z:56​

Answers

Answer:

Each value has been identified below.

Step-by-step explanation:

(1) We have to describe two ways the numbers in each proportion are related;

(a) 5 : 20 = 125 : 500

One way of describing that the given ratios are in proportion is;

Product of means = Product of extremes

20 [tex]\times[/tex] 125 = 5 [tex]\times[/tex] 500

2500 = 2500

This shows that the given proportion is related.

Another way of describing that the given ratios are in proportion is;

As 5 : 20 = 125 : 500

We will check that; [tex]\frac{5}{125}[/tex] is equal to [tex]\frac{20}{500}[/tex] or not.

[tex]\frac{5}{125} = \frac{20}{500}[/tex]

[tex]\frac{1}{25} = \frac{1}{25}[/tex]

This shows that the given proportion is related.

(b) 10 : 1 = 120 : 12

One way of describing that the given ratios are in proportion is;

Product of means = Product of extremes

1 [tex]\times[/tex] 120 = 10 [tex]\times[/tex] 12

120 = 120

This shows that the given proportion is related.

Another way of describing that the given ratios are in proportion is;

As 10 : 1 = 120 : 12

We will check that; [tex]\frac{10}{120}[/tex] is equal to [tex]\frac{1}{12}[/tex] or not.

[tex]\frac{10}{120} = \frac{1}{12}[/tex]

[tex]\frac{1}{12} = \frac{1}{12}[/tex]

This shows that the given proportion is related.

(c) 75 : 25 = 300 : 100

One way of describing that the given ratios are in proportion is;

Product of means = Product of extremes

25 [tex]\times[/tex] 300 = 75 [tex]\times[/tex] 100

7500 = 7500

This shows that the given proportion is related.

Another way of describing that the given ratios are in proportion is;

As 75 : 25 = 300 : 100

We will check that; [tex]\frac{75}{300}[/tex] is equal to [tex]\frac{25}{100}[/tex] or not.

[tex]\frac{75}{300} = \frac{25}{100}[/tex]

[tex]\frac{1}{4} = \frac{1}{4}[/tex]

This shows that the given proportion is related.

(d) 1 : 3 = 16 : 48

One way of describing that the given ratios are in proportion is;

Product of means = Product of extremes

3 [tex]\times[/tex] 16 = 1 [tex]\times[/tex] 48

48 = 48

This shows that the given proportion is related.

Another way of describing that the given ratios are in proportion is;

As 1 : 3 = 16 : 48

We will check that; [tex]\frac{1}{16}[/tex] is equal to [tex]\frac{3}{48}[/tex] or not.

[tex]\frac{1}{16} = \frac{3}{48}[/tex]

[tex]\frac{1}{16} = \frac{1}{16}[/tex]

This shows that the given proportion is related.

(2) Now we have to determine each value of n in the following given ratios;

(a) 2 : 5 = 8 : n

As we know that Product of means = Product of extremes

5 [tex]\times[/tex] 8 = 2 [tex]\times[/tex] n

40 = 2n

[tex]n=\frac{40}{2}[/tex] = 20

Hence, the value of n is 20.

(b) 2 : n = 6 : 9

As we know that Product of means = Product of extremes

n [tex]\times[/tex] 6 = 2 [tex]\times[/tex] 9

6n = 18

[tex]n=\frac{18}{6}[/tex] = 3

Hence, the value of n is 3.

(c) n : 5 = 12 : 20

As we know that Product of means = Product of extremes

5 [tex]\times[/tex] 12 = n [tex]\times[/tex] 20

60 = 20n

[tex]n=\frac{60}{20}[/tex] = 3

Hence, the value of n is 3.

(d) 8 : n = 4 : 15

As we know that Product of means = Product of extremes

n [tex]\times[/tex] 4 = 8 [tex]\times[/tex] 15

4n = 120

[tex]n=\frac{120}{4}[/tex] = 30

Hence, the value of n is 30.

(3) Now we have to determine each value of z in the following given ratios;

(a) 4 : 8 = 3 : z

As we know that Product of means = Product of extremes

8 [tex]\times[/tex] 3 = 4 [tex]\times[/tex] z

24 = 4z

[tex]z=\frac{24}{4}[/tex] = 6

Hence, the value of z is 6.

(b) 5 : z = 6 : 18

As we know that Product of means = Product of extremes

z [tex]\times[/tex] 6 = 5 [tex]\times[/tex] 18

6z = 90

[tex]z=\frac{90}{6}[/tex] = 15

Hence, the value of z is 15.

(c) z : 14 = 10 : 20

As we know that Product of means = Product of extremes

14 [tex]\times[/tex] 10 = z [tex]\times[/tex] 20

140 = 20z

[tex]z=\frac{140}{20}[/tex] = 7

Hence, the value of z is 7.

(d) 3 : 21 = z : 56​

As we know that Product of means = Product of extremes

21 [tex]\times[/tex] z = 3 [tex]\times[/tex] 56

21z = 168

[tex]z=\frac{168}{21}[/tex] = 8

Hence, the value of z is 8.

Steve weighs 18 more pounds than Ryan. If their weight totals 144 pounds, how much does Ryan weigh?

Answers

Answer:

A) Steve = Ryan +18

B) Steve + Ryan = 144

A) Steve -Ryan = 18 then adding B

B) Steve + Ryan = 162

2 Steve = 162

Steve weighs 81 pounds

Ryan weighs (81 -18) pounds 63 pounds

Step-by-step explanation:

X = Ryan’s weight
X + 18 = Steve’s weight
144 = total weight for both

X + X + 18 = 144 ( equation)
2X = 144 -18 (group your equation)
2X/2 = 126/2 (divide both sides by 2)
X = 63 ( Ryan’s age)
X + 18 = 81 ( Steve’s age)

What’s the simplified expression for the expression below 7(x - 4) - 3(x + 5)

Answers

Answer:

4 x + -43

Step-by-step explanation:

Simplify the following:

7 (x - 4) - 3 (x + 5)

Hint: | Distribute 7 over x - 4.

7 (x - 4) = 7 x - 28:

7 x - 28 - 3 (x + 5)

Hint: | Distribute -3 over x + 5.

-3 (x + 5) = -3 x - 15:

7 x + -3 x - 15 - 28

Hint: | Group like terms in 7 x - 3 x - 28 - 15.

Grouping like terms, 7 x - 3 x - 28 - 15 = (7 x - 3 x) + (-28 - 15):

(7 x - 3 x) + (-28 - 15)

Hint: | Combine like terms in 7 x - 3 x.

7 x - 3 x = 4 x:

4 x + (-28 - 15)

Hint: | Evaluate -28 - 15.

-28 - 15 = -43:

Manny has four pieces of carpet in the shape of a square like the one shown. He wants to use them together to carpet a portion of his basement. What is the area of the space he can cover with carpet?

Answers

Answer:

the area of the space he can cover with carpet =  16x⁴ yards²

Step-by-step explanation:

The shape of the square is not shown in this question.

Let assume that the base of the shape of the square is 2x² yards.

and Manny has four of that.

Then side we known the base, we can calculate for the area of the square.

Area of a square = l²

Area of a square = (2x² yards)²

Area of a square = 4x⁴ yards²

However, since Manny has four pieces of that carpet and wants to use them together to carpet a portion of his basement.

Let the pieces of the carpet be carpet A, B, C and D

where; their side is 2x² yards, then their area = 4x⁴ yards²

the area of the space he can cover with carpet =  A+B+C+D

the area of the space he can cover with carpet =  4x⁴ yards² +  4x⁴ yards² +  4x⁴ yards² +  4x⁴ yards²

the area of the space he can cover with carpet =  16x⁴ yards²

In the 2010 Winter Olympics, American Tim Burke aspired to win an Olympic medal in the biathlon, an event that combines cross-country skiing and target shooting. Unfortunately, he wasn’t as successful as he’d hoped. After the 20K race, where he only hit 15 of his 20 targets, he criticized himself, saying his shooting was way below his average of 85% on the season so far. What does it mean if we claim that Burke’s ability to hit a target is 85%?

Answers

Answer:

If we claim that his ability to hit a target is 85% it means that he normally hits 17 out of 20 targets or 85 out of every 100 targets

Step-by-step explanation:

The percentage value has no unit and is used to compare proportion of items or to serve as a visible guide to the relative proportion event occurrence or prevalence of a characteristics within a population.

In the question, we have, the athlete's hitting average given as 85% of targets which means when presented with 20 targets, he is expected to hit 85% of the targets which is 0.85 × 20 = 17 hits.
