Hi!
The formula for volume is length * width * height
We are given the area of the base of the figure and the height.
The volume for area is length * width
That means that the length * width part of the volume formula is already done, so we just have to multiply that by the height.
[tex]3 \frac{3}{8}[/tex] * [tex]2[/tex]
[tex]6 \frac{6}{8}[/tex] [tex]= 6\frac{3}{4}[/tex]
For other volume-related questions, see:
https://brainly.com/question/18571772
We know that:
Volume = L × B × HIf L and B are multiplied, they will find the area of the base.L × B = Area of base of rectangular prism.If L and B are multiplied, they will find the area of the base.
This means that:
Area of base of rectangular prism = L × B = 3 3/8 units²Volume = Area of base of rectangular prism × HSubstitute the area of base of rectangular prism in the volume formula.
Volume = Area of base of rectangular prism × H=> Volume = 3 3/8 × HSubstitute the height in the volume formula.
=> Volume = 3 3/8 × 2You can further solve this in two methods. You can use any of them.
Method #1:Convert the mixed fractions into improper fraction.
=> Volume = [(3 × 8 + 3)/8] × 2=> Volume = [(24 + 3)/8] × 2 [Multiplication first]=> Volume = [(27)/8] × 2=> Volume = 27/8 × 2Multiply the fractions
=> Volume = 54/8 units³ = 27/4 units³Convert the volume into mixed fraction:
27/4 = 24/4 + 3/4 = 6 + 3/4 = 6 3/4 units³Method #2:Break 3 3/8 into smaller parts:
(3 3/8) × 2=> (24/8 + 3/8) × 2Simplify the distributive property:
=> 2(3) + 2(3/8)=> 6 + 6/8 = 6 6/8 = 6 3/4 units³Likewise, you can use any method, it will give the same result.

I’m awful at geometry! Please help :)
Answer:
a is 64 degrees
b is 138.6667
Step-by-step explanation:
a is simple because you know a straight line has 180 degrees and since one side is 116 you simply subtract 180-116=64.
b is more complicated. Since a hexagon has a total internal angle of 720. 3 angle measures are given.
720-116- (180-82)-90=416
Since the last three angles are the same, you can divide by 3.
416/3=138.6667
Hopefully I didnt make any calculation errors because there is a lot of calculating for b.

where a₁ is the first term and d the common difference
here a₁ = - 15 and d = 4 , then

Olivia has a dozen apples of the same size
and a dozen pineapples of the same size.
Olivia uses her juicer to extract 12 ounces of
pineapple juice from 7 pineapples and 16
ounces of apple juice from 4 apples. She
makes a pineapple-apple juice blend from an
equal number of pineapples and apples.
What percent of the blend is pineapple juice?
Answer: 30% of the blend is pineapple juice
Step-by-step explanation:
Since 7 pineapples yield 12 oz of juice, 1 pineapple yields 1 5/7 oz of juice.
Since 4 apples yield 16 oz of juice, 1 apple yields 4 oz of juice.
She’s making a pineapple-apple juice where the ratio of apples and pineapples used is 1:1. To find what percent of the blend is pineapple juice:
1 apple to 1 pineapple. The combined amount of juice they produce is 5 5/7 oz. The formula to find what percent of teh blend is pineapple juice is oz of pineapple juice divided by the combined amount of juice in the blend.
1 5/7 divided by 5 5/7 equals 3/10, or 30%.
The fraction of the blend that is pineapple and apple gives the
percentage that is pineapple.
Response:
The percentage of the blend that is pineapple juice is 30%How can the percentage of pineapple juice in the blend be calculated?Amount of juice extracted from 7 pineapples = 12 ounces
Amount of juice extracted from 4 apples = 16 ounces
Therefore;
The amount of juice from 1 pineapple = [tex]\mathbf{\frac{12}{7}}[/tex] ounces = [tex]1\frac{5}{7}[/tex] ounceThe amount of juice from 1 apple = [tex]\frac{16}{4}[/tex] ounces
The amount of juice from 1 apple = 4 ouncesWhich gives;
The amount of juice from 1 pineapple and 1 apple = [tex]\frac{12}{7}[/tex] + 4 = [tex]\frac{40}{7}[/tex] = [tex]5\frac{5}{7}[/tex]
The amount of juice from 1 pineapple and 1 apple = [tex]5\frac{5}{7}[/tex] ouncesThe percentage of pineapple juice is therefore;
[tex]Percentage \ pineapple \ juice \ in \ blend= \dfrac{\dfrac{12}{7} }{\dfrac{40}{7} } \times 100 = \dfrac{12}{7} \times \dfrac{7}{40} \times 100 = \underline{30\% }[/tex]Learn more about percentages here:

If a> 1 then prove that a^2>1
Step-by-step explanation:
a² = a × a
a > 1
a² = (1+d) × (1+d) = 1² + 2d + d²
with d > 0
since d > 0, then so is 2d and also d².
so, a² is the sum of 1² = 1 and something greater than 0.
so, a² > 1

1. Physicians There are about 900,000 active physicians in the United States, and they have annual incomes with a distribution that is skewed instead of being normal. Many different sam- ples of 40 physicians are randomly selected, and the mean annual income is computed for each sample.
a. What is the approximate shape of the distribution of the sample means (uniform, normal, skewed, other)?
b. What value do the sample means target? That is, what is the mean of all such sample means?
Using the Central Limit Theorem, it is found that:
a) The shape is approximately normal.
b) It targets the population mean.
Central Limit TheoremThe Central Limit Theorem establishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].
For a skewed variable, the sampling distribution is also approximately normal, as long as n is at least 30.
Item a:
The variable is skewed, however, the sample size is greater than 30, hence the approximate shape of the distribution is normal.
Item b:
According to the mean of the sampling distributions, given by the Central Limit Theorem, it targets the population mean.

One of the variables have to be equal to each other. So multiply all the terms in the bottom equation by 1.5
You get 3x+6y=37.5
Subtract one equation from another
3x+3y=35
3x+6y=37.5
You get 3y=2.5
Divide both sides by 3
y = 5/6
Now do the same but for X
Multiply the equation by 4/3
4x+4y=46 2/3
