Ration's an be shown in fraction form as you can see now. SO it is just like finding equivalent fractions.

9 / 3 = 3 / 3 = 1
__
36 / 3 = 12 / 3 = 4

Your answer is D. 1/4.

The ratio of the number of beads Karen had to the number of beads Patricia had was 2:5 .After Patricia bought another 75 beads,t

blondinia [14]

K:P=2:5
P+75 it is 4:15
at first, P=5 units
so we have
2:5 and 4:15
since the K units didn't change we conver them to the same
2:5 times 2:2=4:10
so from 4:10 to 4:15 is a change of 75 in the right side
therefor 75=5 units so 75/5=15/1= 1 unit
so at first K=4 units=4 times 1 unit=4 times 15=60
P=10 units so 10 times 15=150

at first
Karen=60
Patricia=150

Tanner cycled 8 miles in 20 minutes .What is the constant of proportionality based on the situation

solmaris [256]

The constant of proportionality based on the situation is 0.4

Step-by-step explanation:

Tanner cycled 8 miles in 20 minutes

We need to find the constant of proportionality based on the situation

1. The distance is proportion to the time, because the distance and

the time increased together

2. If the distance d and the time is t, then d ∝ t

3. The equation of the direct proportion is d = k t, where k is the

constant of proportionality

∵ d = k t

∵ d = 8 miles

∵ t = 20 minutes

- Substitute these values in the equation above

∴ 8 = k (20)

- Divide both sides by 20

∴ k = 0.4

The constant of proportionality based on the situation is 0.4

Help I’ll do anything just help

Gnom [1K]

Answer:

$1) {n}^{2} - 81 \\ (n - 9)(n + 9)$

$2) \: \: {a}^{2} - 121 \\ (a - 11)(a + 11)$

$3) \: \: {n}^{2} - 16 \\ (n - 4)(n + 4)$

$4) \: \: 9 {x}^{2} - 144 \\ {3}^{2} {x}^{2} - {12}^{2} \\ (3x - 12)(3x + 12)$

$5) \: 2 {x}^{2} - 9 \\ (2x - 3)(x + 3)$

$6) \: \: 4 {w}^{2} - 9 \\ {2}^{2} {w}^{2} - {3}^{2} \\ (2w + 3)(2w - 3)$

$7) \: \: 4 {n}^{2} - 1 \\ {2}^{2} {n}^{2} - {1}^{2} \\ (2n + 1)(2n - 1)$

$8) \: \: 1 - 16 {x}^{2} \\ {1}^{2} - {4}^{2} {x}^{2} \\ (1 - 4x)(1 + 4x)$

$9) \: \: {x}^{2} - {y}^{2} \\ (x - y)(x + y)$

$10) \: \: 9 - {c}^{2} \\ {3}^{2} - {c}^{2} \\ (3 - c)(3 + c)$

$11) \: \: {n}^{2} - 25 \\ {n}^{2} - {5}^{2} \\ (n + 5)(n - 5)$

$13)49 - 4 {a}^{2} \\ {7}^{2} - {2}^{2} {a}^{2} \\ (7 - 2a)(7 + 2a)$

$14) {a}^{2} {b}^{2} - {c}^{4} \\ (ab - {c}^{2} )(ab + {c}^{2} )$

$15) \: \: 4 {x}^{2} {y}^{2} - 9 {z}^{2} \\ {2}^{2} {x}^{2} {y}^{2} - {3}^{2} {z}^{2} \\ (2xy - 3z)(2xy + 3z)$

hope this helps

sorry, I don't know how solve the 12th one.

thanks.

Use the following problem to answer the question below: Given: 3(x – 4) = 33 Prove: x = 15 Statements Reasons 3(x – 4) = 33 Give

lawyer [7]

Answer:

Inverse Property of Addition (Reason C)

Step-by-step explanation:

<u>Given:</u> 3(x – 4) = 33

<u>Prove: </u>x = 15

Statements Reasons

1. 3(x – 4) = 33 Given

2. 3x – 12 = 33 Distributive Property (Reason A)

3. 3x – 12 + 12 = 33 + 12 Addition Property of Equality (Reason B)

4. 3x + 0 = 45 Inverse Property of Addition (Reason C)

5. 3x = 45 Zero Addition Property (Reason D)

6. x = 15 Division Property of Equality
