Answer:
b < - [tex]\frac{3}{7}[/tex]
Step-by-step explanation:
Given
[tex]\frac{2}{7}[/tex] > b + [tex]\frac{5}{7}[/tex] ( multiply through by 7 to clear the fractions )
2 > 7b + 5 ( subtract 5 from both sides )
- 3 > 7b ( divide both sides by 7 )
- [tex]\frac{3}{7}[/tex] > b , then
b < - [tex]\frac{3}{7}[/tex]

3. Ana's bedroom measures 8-feet by 12-feet. She
wants to set up a corner of her room for arts and
crafts and wants to use one fourth of the dimensions
of her room for it. What will be the area of her arts
and crafts corner?
Please help me! Show work please. Sorry:(
If she wants one fourth of the dimensions of the room for the corner, that means the area will be 1/16 (one fourth squared) of the whole bedroom. The area of the whole bedroom is 8 x 12 = 96. The area of the corner would be 96 / 16 = 6 sq ft.
Or you can do (one fourth of 8) x (one fourth of 12) = 2 x 3 = 6 sq ft.

A3 out of 4 women prefer Silly Soap.
B. More people use Silly Soap than any other brand.
C. Any claim would not be accurate since it is likely that moa respondents were women,
D. Any claim would not be accurate since the survey was given to Silly Soap consumers.
The required claim can the company make is that 3 out of 4 women prefer Silly Soap. Option A is correct.
Given that,
Consumers who bought Silly Soup were placed to respond to an internet survey comparing,
The product to other cleaners. If 600 of the 800 people said they preferred Silly Swap.
To determine what claim can the company make.
The ratio can be defined as the proportion of the fraction of one quantity towards others. e.g.- water in milk.
Here,
From given,
600 of the 800 people said they preferred Silly Swap.
implies,
Ratio = 600 / 800 = 3 / 4
Thus, the required claim can the company make is that 3 out of 4 women prefer Silly Soap. Option A is correct.

30 % of the total does Leah have.
What is Percentage?percentage, a relative value indicating hundredth parts of any quantity.
Given,
Leah wants to buy a necklace for her mother's birthday that costs $48.50.
Leah has currently $14.55.
We need to find 14.55 is what percentage of 48.55.
Let x be the percentage.
48.55x=14.55
Divide both sides by 48.55
x=14.55/48.55
x=0.299
Now multiply with 100
x=0.299×100=29.9
x=30%
Hence, 30 % of the total does Leah have.

The ratio of fish to turtles in a pond is
20:3. There are 80 fish in the pond.
How many turtles are in the pond?
A 10
14
C 12
D 16
Answer:
C : 12
Step-by-step explanation:
Answer:
12 turtles
Step-by-step explanation:
First, if the ratio of fish to turtles is 20:3 and there are 80 fish, then we know that you have to divide 80 by 4 to get the answer 20. However, to find out how many turtles there are you need to do the opposite and multiply instead of dividing. So you do 3 x 4, which get you your answer.

Given Point A (3,-4) and Point B (8,6) on directed line segment AB, what is the y-coordinate of Point F
that partitions AB in the ratio of 3:2?
Answer:
(6,2) y-coordinate is 2
Step-by-step explanation:
The coordinates of the point F on directed line segment AB that partitions AB in the ratio 3 :2 are: (6, 2)
What is Coordinate geometry?The formula for finding the coordinates of a point that divides the line in ratio m:n are given by:
We are given that Point A (3,-4) and Point B (8,6) on directed line segment AB.
Here (x1,y1) and (x2,y2) are coordinates of the two points line passed through
(x1,y1) = A(-3,-4)
(x2,y2) = B(8,6)
Ratio: 3 : 2
m = 3
n = 2
Putting the values in the formula
( x, y) = (3 x 8 + 2 x 3 /5 , 3 x 6 + 2 x (-4) /5 )
( x, y) = (24 + 6 / 5 , 18 - 8 /5)
( x, y) = (30/5, 10/5)
( x, y) = (6, 2)
Hence,
The coordinates of the point F are: (6, 2)

En 4 años, Jake será dos veces mayor que Jane. Actualmente, Él es tres veces mayor que Jane. ¿Cuántos años tendrá Jake en 5 años?
Answer:
17 años
Step-by-step explanation:
Deje que la edad de Jane sea x
Deja la edad de Jake por y
y = 3x ------- 1
y + 4 = 2 (x + 4)
y = 2x + 8 - 4
y = 2x + 4 ------- 2
x = y / 3 ------- 3
Sustituye 3 en 2
y = 2 (y / 3) + 4
Multiplicar por 3
3y = 2y + 12
3 años - 2 años = 12
y = 12
Pero y = 3x
Por eso;
x = 12/3
x = 4
Dentro de cinco años
Jake = 12 + 5 = 17años

What is a function?The function is defined as a mathematical expression that defines a relationship between one variable and another variable.
What are Arithmetic operations?Arithmetic operations can also be specified by adding, subtracting, dividing, and multiplying built-in functions.
The operator that performs the arithmetic operations is called the arithmetic operator.
* Multiplication operation: Multiplies values on either side of the operator
For example 4*2 = 8
We have been given that function rule = 4x.
To determine the output for the input is 5
The input given is 5, hence we must substitute x with 5.
So, the output of the function rule = 4(5) = 20.
Therefore, the output of the function rule is 20 for the input is 5.

5x + 2y = 44
5x +2(3x) = 44

Solve [tex]\sqrt{384}[/tex] without going into decimals.
(Answer is below)
Let's solve this step-by-step.
1. Prime factorization of 384.
[tex]=\sqrt{2^7\times3}[/tex]
2. Apply the exponent rule. (Formula: [tex]a^b^+^c=a^b\times a^c[/tex])
[tex]=\sqrt{2^6\times2\times2\times3}[/tex]
3. Apply the radical rule. (Formula: [tex]\sqrt{ab} =\sqrt{a}\sqrt{b}[/tex] or [tex]a\geq 0,b\geq 0[/tex])
[tex]=\sqrt{2^6} \sqrt{2\times3}[/tex]
3a. Solve 2 to the 6th power.
[tex]\sqrt{2\times2\times2\times2\times2\times2} =8[/tex]
4. Multiply 2 by 3. (Note: Put the 8 in your final answer)
[tex]\sqrt{2\times3} =8\sqrt{6}[/tex]
Your answer is: [tex]8\sqrt{6}[/tex]
