Emily's car broke down the weekend before she started a new job. She borrowed $880 from her parents, at an annual interest rate of 3%, to quickly pay for the car repairs. If Emily paid her parents a total of $893.20 in six months, how much simple interest did she pay?
Answer:
$13.2Step-by-step explanation:
Step one:
given data
principal=$880
rate= 3%
final amount = $893.2
time t= 6 months =0.5 years
Step two:
Required
Simple interest
SI=PRT/100
SI=880*3*0.5/100
SI=1320/100
SI=13.2
She paid Simple interest of $13.2
A 30-foot electric line is suspended between the tops of two 20-foot electric poles on ground level. The lowest point of the line is 5 feet above the ground. What is the distance between the two electric poles?
Answer:
The appropriate response will be "Zero (0)". A further explanation is given below.
Step-by-step explanation:
This does not make any logical sense, it seems to be 15 feet from either the peak including its poles to something like the edge of that same wire, therefore half including its 30 would be 15 feet. This always implies that perhaps there is no space seen between points, the poles must've been interacting or overlapping.The response is therefore "0".

the area of the retangler piece of foil is 11 1/4 square inches its length is 4 1/2 inches what is the width of the foil?
Answer:
The width of the foil = w = 2.5 inches
Step-by-step explanation:
We know that the Area of a rectangular piece:
[tex]A=wl[/tex]
Here:
'w' is the width 'l' is the lengthGiven that area of the rectangular piece of foil:
Area = A = 11 1/4 square inches
= 45/4 square inches
= 11.25 square inches
Length = l = 4 1/2 inches
= 9/2 inches
= 4.5 inches
Using the Area formula
[tex]A=wl[/tex]
[tex]w\:=\:\frac{A}{l}[/tex]
[tex]=\frac{11.25}{4.5}[/tex]
[tex]= 2.5[/tex] inches
Thus, the width of the foil = w = 2.5 inches

If a = –2 – 5i and b = –i, then find the value of the ab^3 in fully simplified form.
Answer:
5 + 2i
We were given the complex numbers;
a = - 2 - 5i
and
b = - i
We want to find the product;
ab^3 ^ = Exponent
We substitute the complex numbers into the expression and simplify
( - 2 - 5i ) (i)^3 ^ = Exponent
This is rewritten as:
( - 2 - 5i) (i)^2 x i ^ = Exponent
Note that
i^2 = - 1 ^ = Exponent
We substitute to obtain:
( - 2 - 5i ) x - i
Let us expand to get:
- 2 x - i + 5i x - i
This simplifies to:
2i - 5i^2 ^ = Exponent
This gives:
2i - 5 ( - 1 ) = 2i + 5
Hope This Helps

The value of ab³ in simplified form is; -250(i + 1).
What is an equation?Equations are mathematical expressions that have two algebras on either side of an equal (=) sign. The expressions on the left and right are shown to be equal, demonstrating this relationship. L.H.S. = R.H.S. (left-hand side = right side) is a fundamental simple equation.
From the given values in the question we have;
a = -2 + 2i
b = -5i
Thus
ab³ = (-2 + 2i) × (-5 i)³
= (-2 + 2i) (-125 i³)
= (-2 + 2i) (-125 (-i))
= (-2 + 2i) (+125 i)
= 125 i(-2) + 125 i(2i)
= -250 i + 250 i²
= -250 i -250 or,
ab³ = -250 (i+1)

Jared can run 4 laps in 10 minutes. How long will it take to run 6 laps? Please explain in ratios. 15 points
Please solve and explain
Answer:
The value of x = 15
Hence,
AB = x = 15 inBC = 2x+1 = 2(15)+1 = 30+1 = 31 inAC = x-3 = 15 - 3 = 12 inStep-by-step explanation:
We know that the perimeter of a triangle is the sum of all the sides of a triangle.
Given
Perimeter = 58 in
AB = x
BC = 2x+1
AC = x-3
so the equation becomes
Perimeter = AB + BC + AC
58 = x + 2x+1 + x-3
58 = 4x - 2
4x = 58+2
4x = 60
4x/4 = 60/4
x = 15
Thus, the value of x = 15
Hence,
AB = x = 15 inBC = 2x+1 = 2(15)+1 = 30+1 = 31 inAC = x-3 = 15 - 3 = 12 inVERIFICATION
Perimeter = AB + BC + AC
58 = 15+31+12
58 = 58

Answer:
-6
Step-by-step explanation:
1. Solve each equation. a. 4x = -28 b. x - -6 = -2 C.-Y + 4 = -9 d. -3x + 7 = 1 e 25% -11 = -86
Answer:
A,-7
B, 4
C,13
D,2
Step-by-step explanation:
A,Step 1: Divide both sides by 4.
[tex] \frac{4x}{4} = \frac{ - 28}{4} [/tex]
[tex] x = - 7[/tex]
B,Step 1: Add 6 to both sides.
x−6+6=−2+6
x = 4
C, Step 1: Regroup terms.
4−Y=−9
Step 2: Subtract 44 from both sides.
-Y=-9-4−Y=−9−4
Step 3:Simplify -9-4−9−4 to -13−13.
[tex] \frac{ - y}{1} = \frac{ - 13}{ - 1} [/tex]
Y = 13
D,Subtract 77 from both sides.
-3x=1-7−3x=1−7
2, Simplify 1-71−7 to -6−6.
-3x=-6−3x=−6
3,Divide both sides by −3.
[tex] x = \frac{ - 6}{ - 3} [/tex]
4,Two negatives make a positive.
x = 6/3
x = 2.

score to reach his goal? Be sure to include an inequality to represent this
scenario.
Answer:
63 more points
Step-by-step explanation:
275(goal) - 212(current points) = 63(points needed)
Check your work: 212+63=275
He needs to score 63 points
What is 21=14+7x I need help
Answer:
x-1
Step-by-step explanation:
The solution to the equation 21 = 14 + 7x is x = 1.
What is the solution to the equation?Given the equation in the question:
21 = 14 + 7x
To solve the equation 21 = 14 + 7x, start by isolating the variable x to one side of the equation:
21 = 14 + 7x
Subtract 14 from both sides of the equation:
21 - 14 = 14 - 14 + 7x
Add 14 and -14:
21 - 14 = 7x
Subtract 14 from 21:
7 = 7x
Reorder the equation:
7x = 7
Divide both sides by 7:
7x/7 = 7/7
x = 7/7
x = 1
Therefore, the value of x is 1.

Determine the measure of the unknown angle in the triangle.
you add 78 plus 37 then subtract from 180
Answer:
65°
Step-by-step explanation:
Let the unknown angle be ∠ABC
∠ABC + 78° + 37° = 180° (angle sum property of a triangle)
∠ABC + 115° = 180°
∠ABC = 180° - 115°
∠ABC = 65°
∴the unknown angle in the triangle is 65°
