Answer:
(-17 + 9) - 15
Step-by-step explanation:
I think of below sa level as negative numbers, so 17 feet below sea level is -17. Then when he rises 9 feet that would be - 17 + 9. When he decends 15 feet to take another picture thats - 15. Then when you thing of pemdas addition goes first, so i just put parentases around -17 + 9 to get the expression (-17 + 9) - 15

The amount of Jen's monthly phone bill is normally distributed with a mean of $48 and a standard deviation of $6. Fill in the blanks. 95% of her phone bills are between?
Answer: About 95% of her phone bills are between $36 and $60.
Step-by-step explanation:
If population is normally distributed , then by Empirical rule about 95% of the population lies within 2 standard deviations from mean.
Given: The amount of Jen's monthly phone bill is normally distributed with a mean of $48 and a standard deviation of $6.
Then, by Empirical rule
About 95% of her phone bills are between $(48 -2(6)) and $(48 +2(6))
i.e. About 95% of her phone bills are between $36 and $60.
Hence, About 95% of her phone bills are between $36 and $60.

ax - b = c
solve for a
Answer:
a = c /x + b /x
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.
Answer:
a = [tex]\frac{c + b}{x}[/tex]
Step-by-step explanation:
ax - b = c
ax (+b )=c ---> ax = c + b
(a/x) = c + b ---> a = [tex]\frac{c + b}{x}[/tex]
8. Sherry is going to the top of the wheelchair ramp, as shown in the diagram below.
(12.4)
(0,0) 1 2 3 4
7 8 9 10 11 12 13 14
What is the approximate total distance Sherry travels while she is on the ramp?
Round answer to the nearest tenth.
Record your answer and fill in the bubbles on your answer document.
Answer:
12.7 units
Step-by-step explanation:
Formula to get the distance between the two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is,
d = [tex]\sqrt{(y_2-y_1)^2+(x_2-x_1)^2}[/tex]
From the picture attached,
Sherry is at the origin(0, 0) and going to the top (12, 4)
Distance between these points will be,
d = [tex]\sqrt{(12-0)^2+(4-0)^2}[/tex]
d = [tex]\sqrt{160}[/tex]
d = [tex]4\sqrt{10}[/tex]
≈ 12.7 units
Therefore, Sherry has to travel 12.7 units on the ramp.

find the LCM of 36 45 63 and 80
36 = 2*2*3*3
45 = 5*7
63 = 3*3*7
80 = 2*2*2*2*5
Then take each unique factor (2, 3, 5, and 7) and raise each the greatest power it has in any of the input numbers (2^4, 3^2, 5^1, 7^1) and multiply them, and that is your answer.
2*2*2*2*3*3*5*7 = 5040

Answer:
The number goes up 8 each time. The graph also shows that it is proportional it goes thru the origin
Step-by-step explanation:
what could be the domain and range
the domain is what x values the function takes on,
the range is what y values the function takes on
notice the open circle on (-8, -8) that means that it never actually touches (-8, -8)
however, there is a closed circle on (3, 4)
So, the domain is [tex](-8, 3][/tex]
and the range is [tex](-8, 4][/tex]

Answer: 7 pies
Unit price: $3.50
Step-by-step explanation:
1. To find the unit price, you must divide the cost by the amount of pies
11 divided by 3 is 3.70
24.50 divided by 7 is 3.50
2. You now have the unit price. To find the better buy, you need to determine which price is lower.
3.50 < 3.70
3. The better buy is the 7 pies.
Emily's credit card has arrived and she has a balance of $2,350. She only has enough money to pay off $1500. She knows she will have to pay 8% interest on whatever she doesn't pay off. Which proportion should she use to determine how much interest she will have to pay?
Answer:
850 × 8/100
Step-by-step explanation:
Balance in Emily's card = $2,350
Amount paid by Emily = $1,500
Therefore, the amount not paid by her = $2,350 - $1500
= $80.
Also, the interest on the amount not paid = 8% = 8/100
Hence, the proportion representing the interest payable by her is represented by;
Proportion = Amount she does not pay off × Interest paid
= 850 × 8/100
Therefore, the required proportion is 850 × 8/100
