10. Jillian calculates to see if it will take 95 minutes to run 7 miles. She runs the distance in 80 minutes. What is Jillian's percent error?
Answer:
8. 10%
9. 50%
10. 15%
Step-by-step explanation:
I am pretty sure I got it right otherwise I think I have a big problem
Answer:
10 kawaii, the problem is the comparison with the calculated time for Jillian and the actual time for Jillian to run the 7 miles.
%error=(calculated value - experiemental value)/calculated * 100%
%error=(95-80)/95*100%=15/95 *100% = 15.79 ≈ 16% error
Note: 16% error is the approximate error because the numbers have 2 significant figures stated in the problem.
9 the percent error is 33.3%
8 20% error

Solve for y.
−2y+7=−5
Responses
y = 6
y = 1
y = -1
y = -6
Answer: y = 6
Step-by-step explanation:
1. Subtract 7 from both sides to isolate -2y.
-2y = -12
2. Divide both sides by -2 to isolate the y.
y = 6

Ellen bought new fish for her home aquarium. She bought 4 Turquoise Guppies and 3 Sunburst Tetra GLO Fish and spent a total of $41.73. Danielle bought 3 Turquoise Guppies and 5 Sunburst Tetra GLO Fish for a total of $56.02. How much was one Turquoise Guppy.
Answer: Ellen: 4t + 3s = 41.73
Danielle: 3t + 5s = 56.02
t = $3.69 each
Step-by-step explanation:
with 4t + 3s = 41.73 and 3t + 5s = 56.02
you need yo eliminate s to get t so multiply 3t + 5s = 56.02 by -3/5 to get
-9/5t - 3s = -33.612 then add 4t + 3t = 41.73 to get
11/5t = 8.118 then divide 8.118 by 11/5 to get
t = 3.69

supplementary angles are when two angles sum up to 180 degrees.
∠x and ∠y are supplementary angles
===============
∠x + ∠y = 180°∠x + 116° = 180°∠x = 180° - 116°∠x = 64°Answer:
64°
Step-by-step explanation:
Supplementary angles are two angles that add up to 180°.
∠x + ∠y = 180° <== substitute 116° for ∠y
∠x + 116° = 180° <== subtract 116 from both sides
- 116 - 116
∠x = 64° <== measure of ∠x
Therefore, the measure of ∠x is 64°

a baby gorilla had a mass of 2620 grams at birth, 2960 after 10 days, and 3300 grams after 20 days. What is the average number of grams that the baby gorilla grew each day during the first 10 days and during the next 10 days?
show work
The baby gorilla grew 340 grams in the first 10 days. This is an average of 34 grams per day. The baby gorilla grew 340 grams in the next 10 days. This is an average of 34 grams per day. The baby gorilla grew at the same rate in the first 10 days and the next 10 days.
Here is the solution:
340 grams / 10 days = 34 grams per day
340 grams / 10 days = 34 grams per day
34 grams per day = 34 grams per day
Therefore, the average number of grams that the baby gorilla grew each day during the first 10 days and during the next 10 days is 34 grams per day.

Which is the more reasonable measurement of the distance between the tracks on a DVD: 7.4 ⋅ 10−4 mm or 7.4 ⋅ 104 mm? Justify your answer.
Answer:
A- 7.4 ⋅ 10−4 mm
Step-by-step explanation:
Well, to solve this problem, we must convert the number and / or the units in a more imaginable one.
We are given two choices:
a. 7.4 x 10^-4 mm
b. 7.4 x 10^4 mm
Converting the units and numbers into meters and general form, respectively. (What is meant by general form is not to write it in scientific notation).
a. 7.4 x 10^-4 mm (1 m / 1000 mm) = 0.00000074 m
b. 7.4 x 10^4 mm (1 m / 1000 mm) = 74 m
Now comparing the two values above, what do you think is the distance between the tracks on a DVD? Definitely NOT 74 m or else the DVD is extremely big. Therefore the correct is the smaller one.

Find the number of posobilities-
For lunch, you have a choice of nachos or a fish sandwitch, green beans or french fries, strawberries or jello, and white or chocolate milk. Assuming you chose one of each, how many lunches are possible?
How many possible passwords made up of 4 letters are possible if no letter can be repeated?
Answer: 16 different lunch options
Step-by-step explanation:
Since each time, you have two new options so you have to multiply by 2.
Work backwards.
You have white or chocolate milk. You can have Strawberries or Jello with two different options so in total you have 2 * 2 = 4 different lunches. Then You have green beans or french fries each with 4 different options so 2 * (2*2) = 8 different lunches now. Then you nachos or a fish sandwich each with 8 different options so 2 * (2 * (2*2)) = 16 different lunch options.
In simpler form, you can do, 2 * 2 * 2 * 2 = 16 or \(2^{4}\) = 16, for the four different choices you have.
64 Options.
So there is 7 options which is the nachos, fish sandwich, green beans, fries, strawberries, jello, and 2 different milks. First, add all the foods 1 + 1 + 1 + 1 + 1 + 1 + 2 = 8. Next, multiply the 8 by 8 and it will give you 64.

A florist orders roses and carnations. The roses cost $16 per dozen, and the carnations cost $9 per dozen. The florist orders a total of 18 dozens of roses and carnations for a total cost of $218.
How many dozens of roses does the florist order?
A. 6 dozen
B. 8 dozen
C. 10 dozen
D. 12 dozen
Answer:
B. 8 dozen
Step-by-step explanation:
Let r = number of dozens of roses.
Let c = number of dozens of carnations.
c + r = 18
9c + 16r = 218
-9c - 9r = -162
9c + 16r = 218
7r = 56
r = 8
Answer: B. 8 dozen
Answer: Its 8 dozen
Step-by-step explanation: 1. you multiply 8 times 16 and you get $128
2. you then multiply the remaining carnations by 9. 9 times 10 is $90
3. $128 + $90 is $218
