Answer:

1. z = 5,  2. w = 9

Step-by-step explanation:

1. 5z - 4 = 21

5z = 21 + 4

5z = 25

z = 25/5

z = 5

2. w/9 + 2 = 3

w/9 = 3 - 2

w/9 = 1

w = 1 x 9

w = 9

Anyone know this?? Question: find the area of the shape. Don’t forget your units and use 3.14 if you need to use pi.

Answers

Quick answer :

Area of this shape = 614²

Answer with steps :

Length of side of the first square = 10

It's area :

[tex] =\tt side \times side[/tex]

[tex] = \tt10 \times 10[/tex]

[tex] = \tt {100}^{2} [/tex]

Thus, the area of the first square = 100²

Length of the side of the second square = 10

It's area :

[tex] = \tt \: side\times side[/tex]

[tex] =\tt 10 \times 10[/tex]

[tex] = \tt{100}^{2} [/tex]

Thus, the area of the second square = 100²

Length of the side of the third square = 10

It's area :

[tex] =\tt side \times side[/tex]

[tex] = \tt 10 \times 10[/tex]

[tex] = \tt {100}^{2} [/tex]

Thus, the area of the third square = 100²

(pi value = 3.14)

Radius of the first semicircle = 10 cm

It's area :

[tex] = \tt \: \frac{\pi {r}^{2} }{2} [/tex]

[tex] = \tt \frac{3.14 \times 10 \times 10}{2} [/tex]

[tex] = \tt\frac{3.14 \times 100}{2} [/tex]

[tex] =\tt \frac{314}{2} [/tex]

[tex] =\tt {157}^{2} [/tex]

Thus, the area of the first semicircle = 157²

Area of the second semi circle :

= area of the first semicircle

= 157²

Thus, the area of the second semicircle = 157²

Total area of the figure :

= Area of the 3 squares + Area of the two semi circles

[tex] =\tt 100 + 100 + 100 + 157 + 157[/tex]

[tex] = \tt300 + 314[/tex]

[tex] = \tt {614}^{2} [/tex]

Therefore, the total area of the figure = 614²

5.26 is less than 5.4

Answer:

5.26 < 5.4

Step-by-step explanation:

I hope it's okay that I didn't use the number line.

Try rounding the numbers. 5.26 would round to 5.3, which is less than 5.4. Therefore, the answer is 5.26 < 5.4.

Answers

answer: false

distribute this and keep solving using PEMDAS:

9-3(y-2)=3-3y

- - > 15 - 3y = 3 - 3y

this is false since when you solve you do not end up with the exact same expression.

Answer:

x = 10

Step-by-step explanation:

set up a proportion based on corresponding sides:

4x+ 2/3x = 28/20

cross-multiply:

28/20 can be simplified to be 7/5

5(4x + 2) = 7(3x)

20x + 10 = 21x

10 = x

over the past ten years, the towns population doubled in size. the population is currently 12,000. what was the population ten years ago?

which of the following represents the given word problem if “P” represents the population ten years ago?
1. P=2(12,000)
2. 2P=12,000
3. 2(P+10)=12,000

Answers

Answer:

If P represents the population ten years ago, the current population can be expressed as: 2P = 12,000 (or: 2 x 6,000 = 12,000). Over the past ten years, the town's population doubled in size. The population is currently 12,000. Therefore the population ten years ago was 12,000 divided by 2 = 6000.
