Answer:
5 years old
Step-by-step explanation:
Able has a younger sister and an older brother.
Able’s age can be represented by x.
Able’s sister (s) is 4 years younger than him. This can be represented as:
s = x - 4 [1]
Able’s older brother (b) is twice as old as he is. This can be represented as:
b = 2x [2]
The combined age of all three siblings is 32. This can be represented as:
x + s + b = 32 [3]
If we replace [1] and [2] in [3], we get:
x + (x - 4) + 2x = 32
4x = 36
x = 9
The age of Able's younger sister is:
s = x - 4 = 9 - 4 = 5
A SURVEY OF 1,000 PEOPLE WAS DONE BY NEW YORK TIMES. 90% OF THE PEOPLE
DID NOT KNOW THE NAME OF THEIR REPRESENTATIVE IN CONGRESS. HOW MANY
OF THE 1,000 PEOPLE KNEW THE NAME OF THE CONGRESSMAN?
Step by step explains I need to show my work !
Answer:
100 people
Step-by-step explanation:
first we gotta find 90% of 1000 to do that we multiply 1,000×90% or 1000×0.90 (same thing)
this equals 900 so 900 people don't know the name of their rep in congress subtract 1000-900 thus 100 ppl know there rep in congress
Answer:
100 people did know they're representative
Step-by-step explanation:
You just have to scale up the problem for example 10% of 100 is 10 but 10% of 1,000 is 100(If you need me to be more clear please let me know)

Which function describes the graph?
2
y= 5x+1
c.
2
y = 5x-1
b.
2
d.
2
y=5x+1
y=54-1
Answer: A
Step-by-step explanation:
The y intercept is positive 1, so it’s not C or D
The slope is positive because it’s going up from left to right so it’s not B
2) C ( t ) = 4t =15
A) find C ( 4 ).
B) Find C ( t ) = 23.
9514 1404 393
Answer:
a) 31
b) t = 2
Step-by-step explanation:
Put the given value into the equation and solve for the unknown.
a) C(4) = 4·4 +15
C(4) = 31
__
b) 23 = 4t +15
8 = 4t
2 = t
Trapezoid W'X'Y'Z' is the image of trapezoid WXYZ
under a dilation through point C.
What scale factor was used in the dilation?
1.) -6/5
2.) -5/6
3.) 5/6
4.) 6/5
W'X' is the dilated image, which is smaller than the original, so the scale factor would be less than 1.
Set up a ratio of the dilated figure to the original:
15/18 divide this by 3 to get 5/6
The answer is 3) 5/6
Final question, solve this equation and show work! Worth 20 points
Answer:
[tex]n=5/2[/tex]
Step-by-step explanation:
We have the equation:
[tex]5^{2n-2}=125[/tex]
Notice that 125 is the same as 5³. So:
[tex]5^{2n-2}=5^3[/tex]
Since they have the same base, the exponents must be equal. Therefore:
[tex]2n-2=3[/tex]
Solve for n. Add 2 to both sides:
[tex]2n=5[/tex]
Divide both sides by 2:
[tex]n=5/2=2.5[/tex]
So, the value of n is 5/2.
And we're done!
Answer:
N = 2.5
Step-by-step explanation:
Ok, so try this.
125 is 5^3, right?
And in this equation, we have 5 to the power of 2n-2 is equal to 125.
You need to make sure that the exponent ends up as 3.
How would you do this?
Try substituting N for 3.
That's too big.
Try Substituting N for 2.
That's a bit too small.
What number is in between 2 and 3?
2.5 is.
N = 2.5
Check your work, and see if you came up with the same answer
Work:
2.5 x 2 = 5
5 - 3 = 2
5^3 = 125

Allie must sell at least 50 gift baskets for the band fund-raiser. She already sold 36 baskets. Write and solve an inequality to determine how many more baskets Allie must sell for the fund-raiser.
Answer:
36+x>=50
I might be wrong but here's my explanation.
Step-by-step explanation:
We first of all know that she MUST sell 50 or more baskets.
Knowing this, we know the inequality sign will be facing the x and the 36 as the baskets can be equal to 50 or greater than 50.
Now we have: 36+x>=50
The x is remaining baskets needed.
If you were to solve the inequality you would get x>=14
Hope this helps! P.s. I'd do a bit more research just in case I'm wrong!! :)
The Bureau of Labor Statistics1 in the US tells us that, in 2010, the unemployment rate for high school graduates with no college degree is 9.7 % while the unemployment rate for college graduates with a bachelor’s degree is only 5.2 %. Find the difference in proportions of those unemployed between these two groups and give the correct notation for the difference, with a minus sign. Since the data come from the census, you can assume that the values are from a population rather than a sample. Use the correct notation for population proportions and use subscripts on the proportions to identify the two groups. Assume high school graduates with no college degree are group 1 and college graduates with a bachelor's degree are group 2. 1Thompson, D., ‘‘What’s More Expensive than College?
Answer:
The difference is [tex]p= 0.045[/tex]
Step-by-step explanation:
From the question we are told that
The proportion unemployment rate for high graduated is [tex] p_1 = 0.097[/tex]
The proportion unemployment rate for college graduate is [tex] p_2 = 0.052[/tex]
Generally the difference in proportions of those unemployed between these two groups is mathematically represented as
[tex]p= p_1 - p_2[/tex]
=> [tex]p= 0.097- 0.052[/tex]
=> [tex]p= 0.045[/tex]

15 and 9 are like terms because they can be simplified together. 15+9, 15-9, 15*9 can all be simplified further.
-10xy and 9x are not like terms because they cannot be simplified without the variables first being defined.

Rewrite the equation so that it does not have any fractions
Answer:
24+9x=5
Step-by-step explanation:
First you need to find the least common multiple of the denominators of the fractions. In this case, it would be 12. Then, multiply the entire equation by this number.
2*12=24,
3/4*12=36/4=9,
5/12*12=60/12=5.
Using these values will give your final equation: 24+9x=5
solve for x and show your work

Help please it’s urgent
Answer:
D
Step-by-step explanation:
We can use d to find out how much x equals which therefore would solve the rest of the equation. We also know that half of a parallelogram= 180 degrees so we know that it wouldn't be c and it wouldn't be any of the others either.

Answer:
B (same slope, lower starting point)
Step-by-step explanation:
The slope on this graph is 5, and the slope of y=5x+5 is 5, so the slopes are the same.
This graph has a y-intercept of -6, which is lower than y=5x+5's intercept of 5, so it starts lower, so B.

if a ferry boat covers 28 miles in 4 hours how much distance will it cover in 12 hours?
Answer:
84 miles in 12 hour
Step-by-step explanation:
12/4 = 3
3*28=84
Answer:
84 miles.
Step-by-step explanation:
First, find the rate of miles travel per hour. It is given that the boat covers 28 miles in 4 hours. Simply divide 28 with 4:
28/4 = 7
The boat covers 7 miles per hour.
Now, multiply 12 hours with 7:
12 hours x 7 miles per hour = 84 miles per 12 hours.
84 miles is your answer.

a school has 2 large patios. one is rectangular and is 24 feet long by 18 feet wide. The other is square and each side is 21 feet long. Which patio has a greater area?
Answer:
The 21' by 21' square patio is larger by 9 square feet
Step-by-step explanation:
[tex]24 \times 18 = 432[/tex]
[tex] {21}^{2} = 441[/tex]
The square patio will have more area than the rectangular one.
What is an area?
The space occupied by any two-dimensional figure in a plane is called the area. The space occupied by the rectangle in a two-dimensional plane is called the area of the rectangle.
Given that the school has 2 large patios. one is rectangular and is 24 feet long by 18 feet wide. The other is square and each side is 21 feet long.
The area of the rectangle is calculated as,
Area = L x W
Area = 24 x 18
Area = 432 square feet
The area of the square is calculated as,
Area = S²
Area = (21)²
Area = 441 square feet
The area of the square is greater than the area of the rectangle.
