B, C, E
Step-by-step explanation:
Elena’s aunt pays her $1 for each call she makes to let people know about her aunt’s new business. The table shows how much money Diego receives for washing windows for his neighbors.
Select all the statements about the situation that are true.
A. Elena makes more money for making 10 calls than Diego makes for washing 10 windows.
Elena:
$1 = 1 call
$10 = 10 calls
Diego:
27 windows = $30
10 windows = $x
Cross product
27*x = 30*10
27x = 300
x = 300/27
x = $11.11
Statement A not true
B. Diego makes more money for washing each window than Elena makes for making each call.
Diego:
10 windows = $11.11
Each window = $11.11/10
= $1.11
Statement B is true
C. Elena makes the same amount of money for 20 calls as Diego makes for 18 windows
Elena:
20 calls = $20
Diego:
18 windows = 18 × $1.11
= $19.98
Approximately $20 to the nearest whole dollar
Statement C is true
D. Diego needs to wash 35 windows to make as much money as Elena makes for 40 calls.
Diego
35 × $1.11 = $38.85
Approximately $39
Elena:
40 calls = $40
Statement D is not true
E. The equation y = x, where y is the number of dollars and x is the number of calls, represents Elena’s situation.
Statement E is true
Factor the expression below.
x2 + 12x + 36
O A. (x + 9)(x+4)
O B. (x - 9)(x-4)
C. (x+6)(x+6)
O D. by-6)(x-6)
I was thinking c but I don’t know
Answer:
Step-by-step explanation:
Yes it is C, u are right
Answer:
C (x + 6)(x + 6)
Step-by-step explanation:
Look for 2 factors of 36 that add up to twelve. 6 and 6 do that, so
[tex]x^{2} + 12x + 36 = (x+6)(x + 6)[/tex]
Foil to check
- 10x - 5y = 5 - 4x + 5y = 23

Explanation :
First, you need to convert the mixed numbers into improper fractions. Then, you make sure the denominators are the same. (For example, in the first problem, you have to change the 3/4 to 6/8 to match the 17/8.) Then, you subtract the two fractions, and then turn the resulting improper fraction to a mixed number!

You deposit $500 in a savings account that earns 2.5% interest compounded yearly what is the balance in the account after 20 years
Answer:
the balance in the account after 20 years is $819
Step-by-step explanation:
The computation of the balance in the account after 20 years is shown below:
As we know that
Future value = Present value × (1 + rate of interest)^number of years
= $500 × (1 + 2.5%)^20
= $500 × 1.025^20
= $819
Hence, the balance in the account after 20 years is $819

Subtract (-3f - 4g + 9) - (2 - 6f + 5g).
Answer:
Step-by-step explanation:
Remove the brackets. Watch out for that minus sign. It affects all three terms in the right bracket.
(-3f - 4g + 9) - (2 - 6f + 5g)
-3f - 4g + 9 - 2 + 6f - 5g
+3f - 9g + 7 is your answer.
Answer:
3f−9g+7
Step-by-step explanation:
(−3f−4g+9)−(2−6f+5g)
To find the opposite of 2−6f+5g, find the opposite of each term.
−3f−4g+9−2−(−6f)−5g
The opposite of −6f is 6f.
−3f−4g+9−2+6f−5g
Subtract 2 from 9 to get 7.
−3f−4g+7+6f−5g
Combine −3f and 6f to get 3f.
3f−4g+7−5g
Combine −4g and −5g to get −9g.
3f−9g+7

Jeremy is 12 4 5 years old. Carl is 1 1 6 years younger than Jeremy and Jane is 1 1 3 years younger than Carl. How old is Jane?
Answer: Jane is 10 9/30 years old
Step-by-step explanation:
Given that Jeremy is 12 4 /5 years old
Carl is 1 1/6 years younger than Jeremy which is why we would subtract giving us
=12 4/5 - 1 1/6
= 11 (24- 5)/30
= 11 19/30 years
and Jane is 1 1 3 years younger than Carl which is why we would subtract giving us
=11 19/30 - 1 1/3
= 10 ( 19 - 10)/ 30
=10 9/30 years
What is the area of this?
[tex]area = lw \\ area = (7.5)(6) \\ area = 45 {feet}^{2} [/tex]
[tex]area = \frac{1}{2} bh \\ area = \frac{1}{2} (6)(4) \\ area = \frac{1}{2} (24) \\ area = 12 {feet}^{2} [/tex]
total area = 45 + 12
total area = 57 feet²
Is the ordered pair (4,-3) a solution for the following system of linear inequalities?
x+y<+1 y<5x-2
Answer:
no
Step-by-step explanation:
(4, -3) when plugged into the inequality x + y < 1 is not true
4 + (-3) < 1 is not true because 1 is not less than 1
The law of reflection states that when a ray of light reflects off a surface, the
angle of incidence is equal to the angle of reflection.

- The local museum requires 2 adult
chaperones for every 15 students. How
many adults would be needed with
90 students?
Answer:
For 90 students, 12 adult chaperones are required.
Step-by-step explanation:
90 (students) divided by 15 gives us a proportion to multiple the amount of adults by.
90/15 = 6
Since there are 6 times as many students as the question provided, we will multiply the amount of adults in the question by 6.
2 x 6 = 12
cómo puedo allar el valor absoluto de -4
Answer:
4
Step-by-step explanation:
abs(-4)=4
Answer:
Si recuerda, el valor absoluto de un número es el número "hecho positivo" al eliminar el signo menos si el número es negativo y simplemente dejar pasar el número si es positivo. Entonces, por ejemplo, el valor absoluto de -3 es 3 y el valor absoluto de 3 es 3.
