Answer:
[tex] { - 3}^{4} = - (3 \times 3 \times 3 \times 3) \\ {( - 3)}^{4} = ( - 3 \times - 3 \times - 3 \times - 3)[/tex]
The difference is that (-3)^4 has a negative 3 with parenthesis around it, which means that if it was in PEMDAS, you would work that out first.
For the first four days of a five day vacation, the mean temperature was 80 degrees. What must the temperature be on the fifth day in order for the mean temperature to be 82 degrees?
Answer:
The 5th day must be 90
Step-by-step explanation:
The first 4 days averaged out to 80
You can find their total just by multiplying by 4. That won't tell you the exact values, but it will tell you their total when you add the 4 of them together.
80*4 = 320
Now you need to add another day into the mix. Call it x
320 + x
Now there are 5 days, not 4, and the new total is 82.
(320 + x) / 5 = 82 Multiply both sides by 5
5*(320 + x) / 5 = 82 *5
320 + x = 410 Subtract 320
-320 -320
x = 90
find the value of x pls help

Use the distributive property to writer an equivalent expression 4(7u + 4w - 8)
Answer:
28u+16w-32
Step-by-step explanation:
Distributive property means you multiply everything on the inside of the parentheses by everything on the outside so....
4(7u)=28u
4(4w)=16w
4(-8)=-32

Jaden is comparing two cones. The radius of the base of cone AA is twice as large as the radius of the base of cone BB. The height of cone BB is twice the height of cone AA. The volume of cone AA is
Answer:
VA = 2/3πrB²hB
Step-by-step explanation:
Let the volume of cosA ad cone B be expressed as;
Va = 1/3πra²ha
Vb = 1/3πrb²hb
If the radius of the base of cone A is twice as large as the radius of the base of cone B
rA = 2rB
If the height of cone B is twice the height of cone A, then;
hB = 2hA
hA = hB/2
Recall that;
VA = 1/3πrA²hA
VA = 1/3π(2rB)²(hB/2)
VA = 1/3π*4rB²(hB/2)
VA = 2/3πrB²hB
This gives the volume of cone A
Drag the green point on the tape diagram to model a discount of 27%.
If the discount is 27%, then what percent of the original price do you pay?
Answer:
73%
Step-by-step explanation:
Let us have the original price as $100
A discount of 27% will be;
27/100 * 100 = $27
so, the value to be paid will be $100 - $27 = $73
Now, what percentage of $100 is the $73 that was paid
that would be;
73/100 * 100% = 73%
Increased dumping of sewage into a river caused an increase in parasites that attacked the local fish population. Turtles and birds that live in the same community eat the fish. What would happen between the turtles and birds if the fish population decreased by 50% as a result of the parasitism? *
A increased commensalism
B increased competition
C increased mutualism
D increased predation
Answer: The answer you are looking for is “B increased competition”
Step-by-step explanation: The reason why it is the answer b is when two species eat the same type of food and that said food is decreased as much as 50% there will be a lot of competition that will take place because both species want to survive so it is pretty much anyone for themselves.

What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
Substituting the values in the equation , we get
The number of pairs of pants = 2 pairs
The number of pairs of t-shirts = 8 pairs
The number of pairs of shoes = 2 pairs
And , the total number of outcomes A = 2 x 8 x 2
On simplifying the equation , we get
The different outfits does Joseph can choose A = 32 outfits
Hence , the equation is A = 32 outfits

It's an angles question. I keep getting 14 degrees. How do you do it?
Answer:
32
Step-by-step explanation:
By linear pair and exterior angle theorem:
[tex]x \degree + (180 - 99) \degree = 113 \degree \\ \\ x \degree + 81 \degree = 113 \degree \\ \\ x \degree = 113 \degree - 81 \degree \\ \\ x \degree = 32 \degree \\ \\ x = 32[/tex]

A company that makes robotic vacuums claims their newest model of vacuum lasts, on average, two hours when starting on a full charge. To investigate this claim, a consumer group purchases a random sample of five vacuums of this model. They charge each unit fully and then measure the amount of time each unit runs. Here are the data (in hours): 2.2, 1.85, 2.15, 1.95, and 1.90. They would like to know if the data provide convincing evidence that the true mean run time differs from two hours. What are the appropriate hypotheses?
H0: μ = 2 versus Ha: μ < 2, where μ = the true mean run time for all vacuums of this model
H0: μ = 2 versus Ha: μ > 2, where μ = the true mean run time for all vacuums of this model
H0: μ = 2 versus Ha: μ ≠ 2, where μ = the true mean run time for all vacuums of this model
H0: μ ≠ 2 versus Ha: μ = 2, where μ = the true mean run time for all vacuums of this model
Answer:
The answer is C. H0: μ = 2 versus Ha: μ ≠ 2, where μ = the true mean run time for all vacuums of this model

Solve for w by simplifying both sides of the equation, then isolating the variable.
Exact Form: w = 7 2 w = 7 2
Decimal Form: w = 3.5 w = 3.5
Mixed Number Form: w = 3
final answer: choice Bb. 3.5
Step-by-step explanation:The choices are:
a. 3
b. 3.5
c. 4
d. 4.5
The equation is 5 = w + [tex]1\frac{1}{2}[/tex]
5 - [tex]1\frac{1}{2}[/tex] = [tex]3\frac{1}{2}[/tex]
w = [tex]3\frac{1}{2}[/tex]

Answer: a= ______
(NO FILES) IF YOU ANSWER YOU WILL BE MARKED BRAINLIEST :)
Answer:
a= 32
Step-by-step explanation:
Since "a" is a part of a supplementary angle (An angle that adds up to 180º)
What you would need to do is add 58º and 90º (90º because the right angle = 90)
so 58+90 = 148
Then you would subtract 148 from the total of the angle (Which is 180)
so 180 - 148 = 32, And that shows that a = 32

Answer:
8: 190 yd , 9: 30 m, 10: 92 ft
Step-by-step explanation:
for 8, you can spit it up pretty simply. find 10x18 which is 180 and then 5x2 which is 10 so 8 is 190.
for 9, 2x8=18 for the top portion and for the sides 3x2=6, so twelve. Combined its 30m.
for 10, 10x8=80, then 6x2=12. so 92 ft combined.

Mark me brainliest and u shall get our answerMaya owns a house valued at $432,600. She still owes $233,458 on her mortgage. How much equity does she have in the house? (3 points)
Answer:
$199,142
Step-by-step explanation:
Given that
The value of the house i.e. assets is $432,600
The mortgage i.e. liability is $233,458
We need to find out the equity
As we know that
The accounting equation is
Total assets = Total liabilities + total equity
$432,600 = $233,458 + total equity
So, the total equity is
= $432,600 - $233,458
= $199,142
Answer:
No, she is not correct. She has only $30,000 in home equity. Equity is the value of ownership in an asset minus any debts owed on it. $315,000 minus $285,000 is $30,000.
