Robert places $500.00 in the bank for 5 years at a rate of 12%. How much interest will he earn at the end of the five years?
Answer:
97.6
Step-by-step explanation:
Answer:
381.17$
Step-by-step explanation:
the interset is 12% of the account so it increase with it, for example:
-year one: 500 * 12% = 60$
the account become 560$
-year two: 560 * 12% = 67.2$
the account is 627.2$ which is equal to 500 * (112%)^2
so in five years, the account become
500 * (112%)^5 = 881.17$
the interset in 5 years = 881.17 - 500 = 381.17$

"what is the value of a in the equation 81^b=a^4b"
Answer:
Step-by-step explanation:
The value of a in the equation [tex]81^b = a^4^b[/tex] will be 3.
What is an expression?
Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
The expression is,
⇒ [tex]81^b = a^4^b[/tex]
Now,
Solve the expression for the value of b as;
⇒ [tex]81^b = a^4^b[/tex]
Since, 81 = 3⁴
So, We get;
⇒ [tex]3^4^b = a^4^b[/tex]
By comparing, we get;
⇒ a = 3
Thus, The value of a in the equation [tex]81^b = a^4^b[/tex] will be 3.

Step-by-step explanation:
the scale of the map is 1/4 inch =12 miles what is the distance in between Harrisburg and Leighton if 4.5 inches.
7th Grade Math
Answer:
216 miles :3
Step-by-step explanation: alright so is it is 4.5 you just divide 1/4 by 4.5 (
18) 18 x 12 = 216 miles :3
Answer:
Step-by-step explanation:
1/4 inch=12 miles Harrisburg and Leighton= 4.5 inches
1) Set up a proportion: ¼ /12 miles = 4.5 inches/ x miles
(inches across from inches
miles across from miles )
2) Use cross-products to solve: ¼x= 12(4.5)
¼x/¼ = 54/ ¼
x=216miles
The distance between Harrisburg and Leighton is 216miles

Find the surface area of a square pyramid with side length 1 ft and slant height 2 ft.
Find x. Then find the measure of angles A, B and C.

x= 11
A=59
B= 37
C = 84
Step-by-step explanation:
A triangle adds up to 180 °.
So the equation will be a °+ b° + c° = 180°
Next, you combine like terms.
[tex]6x + 3x + 9x+4-15-7 = 180\\18x-18=180[/tex]
Then inverse operation,
[tex]18x-18=180\\18x=198\\x=11[/tex]
After to get a, b, and c you just need to plug in x.
[tex]6(11)-7=a\\3(11)+4 = b\\9(11)-15=c[/tex]

Step-by-step explanation:
Quadrilateral PQRS was translated 5 units to the right and 3 units up to create quadrilateral P'Q'R'S'. Which rule describes this transformation?
A: (x, y) → (x−5, y−3)
B: (x, y) → (x+5, y+3)
C: (x, y) → (x−3, y−5)
D: (x, y) → (x+3, y+5)
Answer:
B
Step-by-step explanation:
As Quadrilateral PQRS was translated 5 units to the right and 3 units up to create quadrilateral P′Q′R′S′.
Therefore, we can conclude that the rule '' A rule for a translation right and up (x + __, y + __) '' describes this transformation.
The transformation which describes the quadrilateral P'Q'R'S' is (x, y) → (x+5, y+3). Therefore, option B is the correct answer.
Given that, quadrilateral PQRS was translated 5 units to the right and 3 units up to create quadrilateral P'Q'R'S'.
What is the translation?A translation in math moves a shape left or right and/or up or down. The translated shapes look exactly the same size as the original shape, and hence the shapes are congruent to each other. They just have been shifted in one or more directions.
Translation rules:
When the shape is moved towards the right by k units, then replace x with x + k.
When the shape is moved up by k units, then replace y with y + k.
So, translated 5 units to the right
x → x+5
Translated 3 units up
y → y+3
The transformation which describes the quadrilateral P'Q'R'S' is (x, y) → (x+5, y+3). Therefore, option B is the correct answer.
