Answer:
Area= 4,200 square feet
Step-by-step explanation:
If I read your question correctly, I'm assuming the dots (".") mean a multiplication sign ("x").
If they are all being multiplied, use PEMDAS to solve this. First, find to value for any exponents you have (in this case, it's [tex]2^3[/tex] and [tex]5^2[/tex]).
[tex]2^3=2*2*2=8\\5^2=5*5=25[/tex]
Now that you have the values for these two exponents, multiply all the numbers together.
8 x 3 x 25 x 7 = 4,200

At the beginning of the week, Yolanda withdrew $75.00 from her savings account. She then used her debit card to buy groceries for $30.89 and gas for $21. At the end of the week, she deposited $100 into her savings account.
Answer:
226.89
Step-by-step explanation:
Answer:
(-) withdraw/earn
(+) deposit/spend
$75.00 - $30.89 - $21.00 + $100 = $123.11
$75 - $30.89 = $44.11
$44.11 - $21.00 = $23.11
$23.11 + $100 = $123.11
which of the following is the contrapositive of he statement, “if it is a horse, then it is an animal”?
Answer:
"if it is not an animal, then it is not a horse"
Step-by-step explanation:
Lets say we had an original statement that is "if a, then b." The contrapositive to this statement would be "if not b, then not a."
To find the contrapositive to a statement, you would swap and negate the hypothesis, or the "a" in the example statements above, and the conclusion, or the "b" in the example statements above.
For the statement "if it is a horse, then it is an animal", to find the contrapositive, lets first swap the hypothesis and conclusion:
"if it is an animal, then it is a horse"
Now lets negate both the hypothesis and conclusion. To do this, lets change the "it is" to "it is not" in both the hypothesis and conclusion.
"if it is not an animal, then it is not a horse"
And now we have the contrapositive to the statement.

are 2d and 4d like terms
Answer: Yes they are like terms
They both have the same variable so that is why they are like terms.
We can think of 'd' representing something like "dogs" maybe
d = 1 dog
2d = 2 dogs
3d = 3 dogs
4d = 4 dogs
and so on
Adding 2d with 4d gets us 2d+4d = 6d meaning we have 6 dogs overall if we started with 2 and added on 4 more. This is one way to help see why we can combine like terms.
In contrast, something like 2c+4d cannot be combined since having 2 cats and 4 dogs doesn't result in 6 cats or 6 dogs. We just simply leave it as 2c+4d.

HELP!!! WILL GIVE BRAINLEST AND POINTS!!! PLEASE SOLVE THESE TWO EQUATIONS!! -2(x + 4) = -16 x/3 + 5 = 10
Answer:
4, 15
Step-by-step explanation:
First of all, simplify the first equation. When you simplify, you get -2x-8 = -16, which you then add 8 to both sides. You get -2x = -8, so you divide both sides by -2 to get 4. In the second equation, you subtract 5 from both sides to get x/3= 5. Multiply both sides by 3 to get the value of x, and you'll get the equation of x=15, which is the answer.

Two brothers Steven and Walter each inherit 41000. Steven invests his inheritance in a savings account with an annual return of 2.7% while Walter invests his inheritance in a cd paying 6.4% annually. How much more money than Steven does Walter have after 1 year
Answer:
Walter earns $1,517 more than Stevens in one year.
Step-by-step explanation:
Giving the following information:
Two brothers Steven and Walter each inherit $41,000
Steven:
Annual return= 2.7%
Walter:
Annual return= 6.4%
To determine the future value for the brothers, we need to use the following formula:
FV= PV*(1+i)^n
Steven:
FV= 41,000*1.027= $42,107
Walter:
FV= 41,000*1.064= $43,624
Difference= 43,624 - 42,107= $1,517
Walter earns $1,517 more than Stevens in one year.

find the perimeter please it said it has to be 20 characters long don’t mind this
Answer:
[tex]16x^2 + 18y[/tex] units
Step-by-step explanation:
The perimeter of a rectangle is [tex]2l+2w[/tex], where l and w are the length and width respectively. Since we know the value of the length and width, we can substitute inside the equation.
[tex]2(x+5y) + 2(8x^2 - x + 4y)\\\\2x + 10y + 16x^2 - 2x + 8y[/tex]
We can now combine like terms to get [tex]16x^2 + 18y[/tex].

Which Venn diagram correctly describes the relationship between Set R and Set Q?
Answer:
D. because all irrational numbers are real numbers.
Step-by-step explanation:
Real numbers include virtually all numbers we can come up with, either negative or positive, rational or irrational, decimals, etc. They are not imaginary numbers.
Irrational numbers include all numbers that cannot be written as a quotient of two integers. They are numbers whose decimals are never terminating. Examples include π, √2 etc.
Irrational are a subset of real numbers.
Therefore, the correct venn diagram that shows this relationship between Set R {real numbers} and Set Q {irrational numbers} is the venn diagram in option D (last option), because, all irrational numbers are real numbers.

What has the same value as |-5| ?
Answer:
5
Step-by-step explanation:
This is because |-5| is equal to 5
Answer:
It is 5
Step-by-step explanation:
The absolute value sign means how many spots that number is away from the 0 on the number line so it makes all numbers positive except if there is a negative sign on the outside of the absolute value sign
A stack of logs has 17 logs on the bottom layer. Each subsequent layer has 3 fewer logs than the previous layer. If the top layer has two logs, how many total logs are in the pile?
Answer:
152 logs
Step-by-step explanation:
This question is an Arithmetic progression question
A stack of logs has 17 logs on the bottom layer.
First term = a1 = 17
We are told that: each subsequent layer has 3 fewer logs than the previous layer.
Common difference = 3
Hence, Second term = 17 - 3 = 14
Third term = 14 - 3 = 11
If the top layer has two logs,
Last term = 2
Step 1
We find the number of layers of logs present
Number of logs in the bottom layer - number of logs in the first layer + 1
= 17 - 2 +1
= 16 layers
Step 2
We are asked in the question to find , how many total logs are in the pile?
This means, we are to find the sum of terms in the Arithmetic progression.
The formula is given as
Sn = n/2(a + l)
Where a = First term = 17
l = Last term = 2
Sn = n/2(17 + 2)
Sn = 16/2(19)
Sn = 8 × 19
Sn= 152 logs
In what order should you stack the machines so that
when 6 is dropped into the first machine, and all four
machines have had their effect, the last machine's
output is 11 ?
f(x)=√x
g(x) -(x - 2)2
h(x) = 2X-7
k(x) = - - 1
Order the functions below so that you use all four
functions.
= k(
k(x) = -2 -1
h(x)=2x - 7
Answer:
[tex]g(x) = -(x - 2)^2[/tex]
[tex]k(x) = -\frac{x}{2} - 1[/tex]
[tex]h(x) = 2^x - 7[/tex]
[tex]f(x) =\sqrt{x}[/tex]
Step-by-step explanation:
Given
Input = 6
Expected Output = 11
Process:
[tex]f(x) =\sqrt{x}[/tex]
[tex]g(x) = -(x - 2)^2[/tex]
[tex]h(x) = 2^x - 7[/tex]
[tex]k(x) = -\frac{x}{2} - 1[/tex]
Required
Arrange the processes to give an output of 11
To answer this question, I'll make use of trial by error methods.
After some attempts, the following is the order of the processes;
Set x = 6
Substitute 6 for x in g(x)
[tex]g(x) = -(x - 2)^2[/tex]
[tex]g(6) = -(6 - 2)^2[/tex]
[tex]g(6) = -(4)^2[/tex]
[tex]g(6) = -16[/tex]
Substitute -16 for x in k(x)
[tex]k(-16) = -\frac{-16}{2} - 1[/tex]
[tex]k(-16) = -(-8) - 1[/tex]
[tex]k(-16) = 8 - 1[/tex]
[tex]k(-16) = 7[/tex]
Substitute 7 for x in h(x)
[tex]h(x) = 2^x - 7[/tex]
[tex]h(7) = 2^7 - 7[/tex]
[tex]h(7) = 128 - 7[/tex]
[tex]h(7) = 121[/tex]
Substitute 121 for x in f(x)
[tex]f(x) =\sqrt{x}[/tex]
[tex]f(121) = \sqrt{121}[/tex]
[tex]f(121) = 11[/tex]
Hence, the processes is:
[tex]g(x) = -(x - 2)^2[/tex]
[tex]k(x) = -\frac{x}{2} - 1[/tex]
[tex]h(x) = 2^x - 7[/tex]
[tex]f(x) =\sqrt{x}[/tex]
