What is the volume of the figure?
What is the volume of a rectangular crystal with a length (1) of 2.2 cm, a width (w) of 2 cm, and a height
(h) of 1.8 cm?
Answer:
7.92 cm^3
Step-by-step explanation:
To find volume all you have to do is multiply the length, width, and height. The answer would be: l * w * h = 2.2 * 2 * 1.8 = 7.92 cm^3.

a number line is divided into 8 equal parts to show eighths. A point is labeled 1/2. Name the equivalent fraction for the labeled point.
Answer:
4/8.
Step-by-step explanation:
4/8 is the correct answer for this question. This is why. If you take 8 and divide it in half, your answer will be 4. Also because fractions are division so the fraction 8/2 equals 4. This means the 1/2 mark is equal to 4.

Helga buys a $64,987 car from a car dealership. The charge for freight is $2300. The car has an air conditioner and Helga will be getting a new licence plate, vehicle permit, and a licence plate registration sticker. What is the total cost of the purchase of the car?
The total cost of the car purchase, including the base price, freight charge, air conditioner cost, and license-related fees, is $68,937.
To calculate the total cost of the car purchase, we need to consider the base price of the car, the charge for freight, and the additional costs for the air conditioner and license-related fees.
Given:
Base price of the car: $64,987
Freight charge: $2,300
Additional costs:
Air conditioner cost: Let's assume it's $500 (not explicitly mentioned in the given information)
License-related fees: Let's assume it's $150 (not explicitly mentioned in the given information)
To calculate the total cost, we add up all the costs involved:
Total cost = Base price + Freight charge + Air conditioner cost + License-related fees
Total cost = $64,987 + $2,300 + $500 + $150
Total cost = $68,937

The article " Inconsistent Health Perceptions for US Women and Men with Diabetes" presents results of a survey of adults with diabetes. The average body mass index (BMI) in a sample of 1559 men was 30.4, with a standard deviation of 0.6. The average BMI in a sample of 1924 women was 31.1 with a standard deviation of 0.2. Find a 99% confidence interval for the difference between the mean weights.
Answer:
The 99% confidence level (-0.741, -0.659).
Step-by-step explanation:
The average body mass index (BMI) in a sample of 1559 men was 30.4, with a standard deviation of 0.6.
The average BMI in a sample of 1924 women was 31.1 with a standard deviation of 0.2.
Find a 99% confidence interval for the difference between the mean weights..
The formula for 99% Confidence Interval for difference between the mean weights =
μ is the population mean, and σ is the population standard deviation.
μ1 - μ2 ± z × √σ²1/n1 + σ²2/n2
The z score for 99% confidence interval = 2.576
30.4 - 31.1 ± 2.576 × √0.6²/1559 + 0.2²/1924
-0.7 ± 2.576 × √0.36/1559 + 0.04/1924
-0.7 ± 2.576 × √0.0002309173 + 0.00002079
-0.7 ± 2.576 ×√0.0002517073
-0.7 ± 2.576 × 0.015865286
-0.7 ± 0.04086897674
Hence, the 99% Confidence Interval is
-0.7 - 0.04086897674
= -0.74086897674
≈ -0.741
-0.7 + 0.04086897674
=-0.65913102326
≈ -0.659
Therefore, the 99% confidence level (-0.741, -0.659).

A box is being packed with cubes that measure 1 cubic foot. What is the volume of the box in cubic feet
Answer:
81 cubic foot
Step-by-step explanation:
It is given that the box is packed with cubes whose side is 1 foot. So the volume of one cube is 1 cubic foot.
Now from the figure, we can see that :
Number of cubes fitting the box across its length = 9 cubes
Number of cubes fitting the box across its width = 3 cubes
Number of cubes fitting the box across its height = 3 cubes
And each of these cubes measures 1 x 1 x 1 cubic foot
So the volume of the box can be found out by:
Volume = length x width x height
= 9 x 3 x 3
= 81 cubic foot
Therefore volume of the box is 81 cubic foot.
If a 12-sided fair die is rolled twice, find the probability that both rolls have a result of 8.
Answer:
1 in 144
Step-by-step explanation:
There is one 8 on a 12-sided die, so the probability of rolling an 8 once is [tex]\frac{1}{12}[/tex].
We are rolling twice, so [tex](\frac{1}{12})^{2} =\frac{1}{144}[/tex].

7 cameras cost $308. The cost of each camera is the same. What is the cost of each camera?
Answer:
$44
Step-by-step explanation:
Hello!
It said that 7 cameras cost $308, right?
If each camera costs the same, it means that 7 cameras with the same value equal $308.
If we use this in an equation, and if x is a variable we want to solve, it would be:
7x = 308.
If 7x = 308, it would be
308/7 =
44.
So, $44 is the answer.

select 2 points fir each of the following equations: y=2x+9 -6x=4+2y
the two points for each equation are:
For y = 2x + 9:
Point 1: (0, 9)
Point 2: (3, 15)
For -6x = 4 + 2y:
Point 1: (0, -2)
Point 2: (2, -8)
How to find the two points of the equationsTo find two points for each of the given equations, we can arbitrarily choose values for x and then calculate the corresponding y values.
For the equation y = 2x + 9:
Let's choose x = 0:
y = 2(0) + 9
y = 9
So, one point is (0, 9).
Let's choose x = 3:
y = 2(3) + 9
y = 6 + 9
y = 15
Another point is (3, 15).
For the equation -6x = 4 + 2y:
Let's choose x = 0:
-6(0) = 4 + 2y
0 = 4 + 2y
-4 = 2y
y = -2
One point is (0, -2).
Let's choose x = 2:
-6(2) = 4 + 2y
-12 = 4 + 2y
-16 = 2y
y = -8
Another point is (2, -8).
Therefore, the two points for each equation are:
For y = 2x + 9:
Point 1: (0, 9)
Point 2: (3, 15)
For -6x = 4 + 2y:
Point 1: (0, -2)
Point 2: (2, -8)

Step-by-step explanation:
In this problem we need to kind of write the picture into an equation so the first thing we see are 4 xs on the far left-hand side this is representing "4x" then we see 5 - blocks on the right which represents "-5" because we have 5 minuses then on the other side we see 7 + blocks which represent just "7". After we identify everything in the picture we can write an equation so 4x -5 = 7. Then we solve so we need to separate x on one side and all the other numbers to the other to do that we can move the -5 to the side the 7 is on and because of math when we move a number to another side of the equation we have to switch the sign it has so if it was -5 then on the other side it would be 5 then we add 7 to 5 which would equal 12. Then we are left with 4x = 12 and to keep x on its own side we need to divide 4 from the other side because it is multiplying on the x side and again we need to switch the sign. then we are left with x=3. Hope this helps!

What is the box and whisker plot?A box and whisker plot is a method of abstracting a set of data that is approximated using an interval scale. It's also known as a box plot. These are primarily used to interpret data.
We have box plot data:
1,000 1,400 1,800 2,200 2,600 3,000
From the box plot:
The shortest distance Estelle swam at practice is given by:
= 1800—(1400+1800)/2
= 1800 – 1600
= 200 meter
Thus, the shortest distance Estelle swam at practice is 200 meters if the Estelle swims for the Shorewood Sharks swim team

write an equation for the function graphed below
The rational function graphed in this problem is defined as follows:
f(x) = -3(x - 2)/(x² - x - 6).
How to define the rational function?The vertical asymptotes of the rational function in this problem are given as follows:
x = -2 and x = 3.
Hence the denominator of the rational function is given as follows:
(x + 2)(x - 3) = x² - x - 6.
The zero of the rational function is given as follows:
x = 2.
Hence the numerator is given as follows:
a(x - 2).
In which a is the leading coefficient.
Hence:
f(x) = a(x - 2)/(x² - x - 6).
When x = 0, y = -1, hence the leading coefficient a is obtained as follows:
-1 = -2a/-6
-1 = a/3
a = -3.
Hence the function is:
f(x) = -3(x - 2)/(x² - x - 6).

The human body is made up of about 9.3% hydrogen. What is the amount of hydrogen contained in a person who weighs 140 pounds? Round you answer to the hundredths place
Answer:
We know that for a human body 9.3% of its total mass is hydrogen.
Now we have a person with a mass of 140 lb.
Then we have that the 100% of the mass is 140lb, the 9.3% of this is hydrogen.
We can write:
9.3% = X
100% = 140lb
We want to find the value of X (mass of hydrogen)
Then we can take the quotient of these two equations to get:
(9.3%/100%) = X/140lb
Now we can isolate the variable X to get:
(9.3%/100%)*140lb = X = 13.02 lb
So this person has about 13.02 lb of hydrogen in his/hers body.

Fiona spent 50 minutes to complete her homework. She spent 30 minutes on her
math assignment and 20 minutes on her science assignment. What fraction of time
did Fiona spend on her math assignment??
Answer:
3/5 of her time
Step-by-step explanation:
She spent 30 minutes out of 50 minutes on her math assignment. So, we can write this fraction:
30 minutes / 50 minutes
Divide both the numerator (top of the fraction) and denominator (bottom of the fraction) by 10 minutes to get
3 / 5
So, the answer is 3/5 of her time.
