Stephanie took advantage of the interest-only financing from Rooms-To-Go and borrowed $2,000 with a 15 percent annual interest rate. How much will she have paid in interest after 8 months?
Answer: $200
Step-by-step explanation
Principal = $2000
Rate = 15%
Time = 8 months = 8/12 = 2/3 years
Interest = Principal × Rate × Time
= 2000 × 15% × 2/3
= 2000 × 15/100 × 2/3
= $200
The interest is $200

Trina collects eggs from her hens.
She labels their eggs small or medium or large.
20% of the eggs she collected in May were small.
24% of the eggs she collected in May were large.
(a) What percentage of the eggs she collected in May were medium?
Answer:
56% of her eggs were medium in may
Step-by-step explanation:
if 20% of the eggs she collected in May were small, 24% of the eggs she collected in May were large. All you have to do is add them up which is 44% and minus it by 100% which is 56%
~Batmans wife dun dun duuuun
What is the answer!!!!!?
Answer:
29 degrees
Step-by-step explanation:
Given
<D = 2x+8
<A = 122
The sum of the adjacent angle of the trapezoid is 180 degrees
<D + <A = 180
2x + 122 = 180
2x = 180-122
2x = 58
x = 58/2
x = 29 degrees
Hence the value of x is 29 degrees

What is the simple interest on $360 borrowed for 30 months at 12.3%?
PLEASE SHOW HOW YOU SOLVEDIT!!! :D
Answer:
$110.70
Step-by-step explanation:
I=PRT
P (principal)=360
R(rate)=12.3%
T(time)=30 months (2 and half years)
I=360*12.3%*2.5
=$110.70
Just to note 12.3% is also 0.123 we sometimes change it into a decimal.
The temperature during one day in Auckland decreases from 21°C to 17°C. Calculate the percentage decrease correct to 3 significant figures.
please i need a quick answer
Answer:
19.04%
Step-by-step explanation:
The temperature decreases from 21°C to 17°C.
We need to find the percentage decrease in the value of temperatures.
The percentage decrease in any value is given by :
[tex]\%=\dfrac{|\text{initial value-final value}|}{\text{initial value}}\times 100\\\\=\dfrac{21-17}{21}\times 100\\\\=19.04\%[/tex]
So, the required percentage decrease is 19.04%.

Today, everything at a store is on sale. The store offers a 20% discount.
1. The regular price of a T-shirt is $24. What is the discount price?
2. If the regular price of an item is x dollars, what is the discount price in dollars?
3. The discount price of a hat is $14. What is the regular price?
Answer:
a) $19.2
b) 0.8x
c) $17.5
Step-by-step explanation:
1. We want to find the discount price given the regular price
The discount is 20%
so the discount price will be;
24 - 20% of 24
24 - 4.8 = $19.2
b) We have this as;
x - (20% of x)
x - 0.2x = 0.8x
c) let the original price be x
x - 20% of x = 14
x - 0.2x = 14
0.8x = 14
x = 14/0.8
x = $17.5

Answer: [tex]12*\sqrt{2}[/tex]
Step-by-step explanation:
We have the equation:
[tex]\frac{14}{\sqrt{2} } + \sqrt{50}[/tex]
we know that:
14*14 = 196
then:
14 = √196
[tex]\frac{\sqrt{196} }{\sqrt{2} } + \sqrt{50} = \sqrt{196/2} + \sqrt{50} = \sqrt{98} + \sqrt{50}[/tex]
Now, we can rewrite:
50 = 2*25
98 = 2*49
This is because we know that 49 and 25 are perfect squares, then:
[tex]\sqrt{98} + \sqrt{50} = \sqrt{2*49} +\sqrt{2*25} = \sqrt{2} *\sqrt{49} + \sqrt{2} *\sqrt{25}[/tex]
Now we can use the common factor √2 and get:
[tex]\sqrt{2} *\sqrt{49} + \sqrt{2} *\sqrt{25} = \sqrt{2}*(\sqrt{49} + \sqrt{25} )[/tex]
and we know that:
7*7 = 49
5*5 = 25
then:
[tex]\sqrt{2}*(\sqrt{49} + \sqrt{25} ) = \sqrt{2}*(7 + 5) = 12*\sqrt{2}[/tex]
the value of b is:

Given right triangle ABCABC with altitude \overline{BD} BD drawn to hypotenuse ACAC. If AC=16AC=16 and DC=3,DC=3, what is the length of \overline{BC} BC in simplest radical form?
Answer:
4√3
Step-by-step explanation:
Find the diagram attached
Using the similarity theorem of a triangle based on the legs (sides)
AC/BC = BC/DC
Given
AC = 16
DC = 3
Required
BC
Substitute the given values
16/BC = BC/3
Cross multiply
BC² = 16×3
BC² = 48
BC = √48
BC = √16×3
BC = 4√3
Hence the measure of BC is 4√3

Answer:
[tex]sin 40 = \frac{x}{11}[/tex]
Step-by-step explanation:
[tex]sine = \frac{opposite}{hypotenuse}[/tex]
Side x is the opposite, since it is opposite the angle you are solving for.
Side y is the adjacent, since it is next to the angle you are solving for.
The side measuring 11 is the hypotenuse, since it is across from the right angle.

20 POINTS
A line passes through the points (7,-3) and (7,11).
a. What is the equation for the line?
b. Does the equation you wrote in part a represent a function? Explain why or why not.
Answer:
x = 7; NO
Step-by-step explanation:
Notice that the x-coordinate remains the same, 7, for both points, whereas the y-coordinate changes. Thus, the line through these two points is a vertical one: x = 7. No, this is not a function, since one x value (7) has more than one y values associated with it.
