Answer: Option A is the correct answer
Step-by-step explanation: I took the test and got it right
The total weight of the two animals is 1.19 x 10³ lbs. So the correct option is B.
Given approximate weights of the two animals are as:
1. 5.12 x 10² lbs
2. 6.8 x 10² lbs
We need to find the total weight of the two animals.
Step 1: Add the weights together:
5.12 x 10² lbs + 6.8 x 10² lbs
Step 2: Perform the addition:
(5.12 + 6.8) x 10² lbs
11.92 x 10² lbs
Step 3: Express the result in scientific notation with the correct number of significant digits:
The first number, 11.92, has three significant digits. To maintain three significant digits in the final answer, we can express it as 11.9 (rounding to the nearest tenth) and adjust the exponent accordingly:
11.9 x 10² lbs
This matches option 2 from your provided answers:
2. 1.19 x 10³ lbs.
So, the correct answer is: 1.19 x 10³ lbs.

Question 1: The following graph shows the number of soccer games a team won in each of their first three seasons. Explain how you could redraw the graph so that the change in wins between three seasons does not seem so great.
Question 2: Why could the mean of the data set below be misleading?
ages of teachers: 29, 38, 39, 26, 29, 29, 39, 77, 38 ,29
Answer: Question 1: For season 1 it is 1,10 for the grid and for season 2 it is 2,8 Question 2: 29, is 14 in the gap to 38 and the rest count by 2s or 10s.
and the season 3 is 3,7
See more below......
Step-by-step explanation:
Question 1: Use a coordinate grid to answer the question.
Coordinate grid is a rectangular plane where the intersection of horizontal and vertical lines forms a grid network.
Question 2: Is you count by 2s or 10s.
2s are you add 2 to get the next number.
10s are counting multiple groups of 10 in a faster way.
Therefore, Question 1 and Question 2 are correct.

Akio has 27 blankets and 18 flashlights to use in emergency relief kits for communities in need. He will put the same number of blankets and the same number of flashlights in each kit. He wants to use all the blankets and flashlights. What is the greatest number of emergency relief kits Akio can make?
Answer:
6
Step-by-step explanation:
The answer Is 6
Answer:
9
Step-by-step explanation:
We can make an equation out of this
So if he has 27 blankets, and 18 flashlights, he will need to divide evenly amongst the kits.
The equation would be
z=x+y, where x is the amount of blankets, and y is the amount of flashlights.
to find this, we need to find what 27 is divisible by, and what 18 is divisible by.
27 - 27, 9 , 3, 1
18 - 18, 9, 6, 2, 3, 1
Now, 18 and 27 are both divisible by 9
18/9=2
27/9=3
So we can make a total of 9 emergency kits, with each kit having 3 blankets and 2 flashlights

Answer: 40
Step-by-step explanation:
4 x (x)/4 = 10 x 4 (4 ÷ 4 = 1, so they'll cancel out)
10 x 4 x 1 = 40
Step-by-step explanation:
so, the whole thing starts out as
x/4 = 10
the next 2 steps are written by your teacher :
multiply both sides now by 4
4 × x/4 = 10 × 4
on the left side (as your teacher stroke through)
4 / 4 = 1
leaving x all by itself.
on the right side
10 × 4 = 40
and you get
x = 40
and there is your result.

The following pie chart represents how many absences the students of Washington Middle School had during the first quarter. What percentage of the students had three or more absences during the first quarter?
Answer:
300
Step-by-step explanation:
Let the total students be x.
Students absent for two or more = 32%
(on adding percentage of both 2 and 3 or more)
32/100x = 96
X = (96*100)/32
X = 300

Describe and correct the error a student made when graphing the linear equation y = - 6.
Answer:
The error is in computing the y intercept. It should be at (0, -6) not (0, 6)
Step-by-step explanation:
The equation of the line is
[tex]-\frac{3}{4} x - 6[/tex]
y intercept is at point x = 0
When x = 0,
[tex]y = -\frac{3}{4} x - 6\\\\y = 0 - 6 \\\\y = -6[/tex]
So y intercept is at point (0, -6)
If we plot a second point 3 units down and 4 units right we should get the point 0 + 4, -6 - 3) = (4, -9)
Plugging this into the original correct equation satisfies the equation
[tex]y = -\frac{3}{4} x - 6\\\\y = -\frac{3}{4} (4) - 6 \\\\y = -3 -6 = -9 \\\\[/tex]
So we can see that the line does pass through (4, -9)

a. 3.5, 1.8 c. 2.7, 1.8
b. 2.3, 3 d. 4.7, 3.1
Answer:
b
Step-by-step explanation:
r = 1.5
Area/A = πr²
= π(1.5)²
= 7.07
A ÷ r = 7.07 ÷ 1.5
= 4.7
A ÷ r² = 7.07 ÷ 1.5²

A gem store in Fort Lauderdale received a shipment of 1 1/2 pounds of moonstone crystals if these moonstones crystals if these moonstone crystals were separated into 6 equal bags how much would each bag weigh?
A shipment of 1.5 pounds of moonstone crystals was divided into 6 equal bags. Each bag would weigh 0.25 pounds, which is the same as 4.0 pounds.
How to solveTo solve this problem, we can use the following equation:
total weight / number of bags = weight of each bag
In this case, the total weight is 1.5 pounds and the number of bags is 6. So, the weight of each bag is:
1.5 pounds / 6 bags = 0.25 pounds per bag
Since 0.25 pounds is the same as 4.0 pounds, each bag would weigh 4.0 pounds.

A pack of 50 sheets of paper costs $1.10. What is the cost per
sheet of paper? Did you multiply or divide to find your answer?
a. $0.022, divide c. $55, multiply
b. $0.022, multiply d. $55, divide
Answer: Choice A
$0.022, divide
======================================================
Work Shown:
50 sheets = 1.10 dollars
50/50 sheets = 1.10/50 dollars
1 sheet = 0.022 dollars
In the second step, I divided both sides by 50 to get the "50 sheets" to turn into "1 sheet". The result of 0.022 dollars is equivalent to 2.2 cents; so the unit cost is a little over 2 cents per sheet.

Julie sees a ride that spins 10 turns each minute. She says it will spin 40 turns in 4 minutes. Is Julie correct? Explain.
Answer:
yes
Step-by-step explanation:
1 minute = 10 turns
4 minutes = 40 turns
• This is direct proportion. As one side increases by a value so must the other. In this case 1 min has become 4 mins. This has been multiplied by 4. So 10 must be multiplied by 4 too. 4 × 10 = 40 turns.
Answer: Yes she is correct
