Answer:
D. 2^7
Step-by-step explanation:
Answer:
2^7
Step-by-step explanation:
When we multiply the same bases with exponents like 2^3*2^4 we can add the exponents and keep the base the same
2^7 would be the answer or you can simplify further to get 128
but they said simplify so 2^7 is the answer
If they said evaluate then our answer is 128
Grace and her brother need $400 to go to band camp. Their parents have agreed
to help them earn money by paying them $25 each time they mow the lawn
and $10 for each hour they babysit their younger brother. They will have to do a
combination of both chores to earn the money.
Select the equation that represents the number of lawns they can mow, m, and
hours they can babysit, b, to earn $400.
M. 10m + 25b = 400
P.
10m - 25b = 400
R. 25m + 10b = 400
S. 25m - 10b = 400
Answer:
R. 25m + 10b = 400
Step-by-step explanation:
25m: $25 for time the mow the lawn
10b: $10 for every hour that they babysit their younger brother
400: They need $400 in total
+ : You need to add what they made for mowing the lawn and for babysitting.

| x+14 | = 14
| x-14 | = 14
| x+8| = x+8
Answer:
if youre just looking for x, it would be x=0.
Step-by-step explanation:
the absolute value of any number is just the positive version of that number. So, |0+14|=14 and the same for the rest of them.

. Evaluate the following: |15 - 47] + 9 - (-2)(-4) - 17|
Answer:
48
Step-by-step explanation:
Since there is an absolute value, the answer must be positive. Multiply 2 by 8 since two negatives equal a positive. So, |15-47 + 9 - 8 -17|. Then add and subtract to get the answer. -32 + 9 - 8 -17 = -48. |-48| = 48
Answer: 50
Step-by-step explanation:
If you get 9 = 0 as your final answer, how many solutions do you have in your set?
A) one solution
B) infinite solutions
C) no solution
D) two solutions
Un alumno multiplica un número por 32 en lugar de multiplicarlo por 23, obteniendo un producto mayor en 54 al producto original. Halla la suma de cifras del producto original
Answer:
La suma de cifras del producto original es igual a 12.
Step-by-step explanation:
De acuerdo a la información proporcionada, si multiplicas un número "x" por 32 su resultado sería igual al producto original "y" más 54 dado que dice que se obtiene un producto mayor en 54 al producto original, lo que se puede expresar de la siguiente forma:
32x=y+54
Además, se puede inferir a partir del enunciado que si el número x se hubiera multiplicado por 23 el resultado habría sido el producto original que lo denominamos como "y", por lo que puedes decir que:
y=23x
Ahora puedes reemplazar y=23x en 32x=y+54 y despejar x:
32x=23x+54
32x-23x=54
9x=54
x=54/9
x=6
Finalmente, puedes reemplazar el valor de x en y=23x:
y=23x
y=23*6
y=138
Suma de cifras: 1+3+8 = 12
De acuerdo a esto, la respuesta es que la suma de cifras es igual a 12.

Find the difference of the complex numbers.
(2 +8i)-(-5 - 3i)
Answer:
7 + 11i
Step-by-step explanation:
Simplify: (2 +8i)-(-5 - 3i) = 2 + 8i + 5 + 3i
Add real numbers to real numbers and imaginary to imaginary: 2 + 8i + 5 + 3i = 7 + 11i
A complex number can be shown as a pair of integers (a, b). The difference of the complex number (2 +8i)-(-5 - 3i) is 7+11i.
What is a complex number?A complex number can be shown as a pair of integers (a, b) forming a vector on an Argand diagram, which represents the complex plane.
The difference of the complex number can be done as following,
(2+8i)-(-5-3i)
= 2 + 8i + 5 + 3i
= 5+2 + 8i+3i
= 7 + 11i
Hence, the difference of the complex number (2 +8i)-(-5 - 3i) is 7+11i.

Answer:
That would be -2n - 1.
Answer:
-2n - 1
Step-by-step explanation:
You have to combine like term which would be 4n,n,and 7n.
Since n doesn't have a variable just add a one in front. So now the equation would be
1n+4n-7n That equation equals -2n
Now just add the remaining number
So that makes the answer -2n -1

The angle of elevation of an electricity pole from a point 8 metres from its base is 52.7 degrees. What is the height of the pole?
Answer:
10.5m
Step-by-step explanation:
We solve the above question, using the Trigonometric function of Tangent
tan θ = Opposite/Adjacent
θ = 52.7 °
Adjacent = 8 m
Opposite = x
Hence,
tan 52.7= x/8m
Cross Multiply
x = tan 52.7 × 8m
x = 10.501501092m
Approximately = 10.5 m
Therefore, the height of the pole = 10.5m

A rake was marked up 25% from an original cost of $8.80. Last Friday, Dean bought the rake and paid an additional 3% in sales tax. What was his total cost?
Answer:
$11.33
Step-by-step explanation:
First I did 8.80 x 0.25 and I got 11. Than I did 11.00 x 0.03 and I got $11.33. The total cost was $11.33
The total cost of the rake is $11.33.
What is the sales tax?Calculating the sales tax applied to a purchase is a matter of simply multiplying the tax rate by the purchase price using the equation sales tax = purchase price × sales tax rate. Adding the sales tax to the original purchase price gives the total price paid with tax.
Given that, a rake was marked up 25% from an original cost of $8.80.
25% of the original cost of $8.80 is
0.25×8.80 =$2.2
So the marked up price was 8.80+2.20
= $11
He then paid an additional 3% in sales tax, that is
11 + 0.03×11 = $11.33
Therefore, the total cost of the rake is $11.33.

"You purchase a vintage car for $140,000 and it appreciates (i.E. Increases in value) by 4% annually. How much will the car be worth in 10 years?"
Answer:
Future Value= $207,234.2
Step-by-step explanation:
Giving the following formula:
Initial value (PV)= $140,000
Appreciation rate (r)= 4% = 0.04
Number of years (n)= 10
To calculate the future value of the car after ten years, we need to use the following formula:
FV= PV*(1+i)^n
FV= 140,000*(1.04^10)
FV= $207,234.2
