A store owner offers a discount of 20% off the regular price of all jackets. Jessica has a coupon that gives her an additional 5% off the discounted price. The original price of the jacket Jessica buys is $84. What is the price of the jacket after the discount and Jessica's coupon?
Answer:
21
Step-by-step explanation:
I haven't done this in a long time but this is what I know: the discount would overall be 25%. So, you set it up by .25(84) = 21. Therefore the jacket would cost $21.
I hope this is right and helps!

What is the measure of the angle at the tail end of the kite? if the top area is where its pointed is 122?
Answer:
The angle is 58 degrees
Step-by-step explanation:
Given
See attachment for kite
Required
The angle at the tail end
Represent this angle with x.
From the attached kite, we have:
1 angle = 122
2 angles = right-angled
So, we have:
[tex]x + 122 +90+90 = 360[/tex] --- sum of angles in a kite
[tex]x + 302 = 360[/tex]
Solve for x
[tex]x =- 302 + 360[/tex]
[tex]x =58^\circ[/tex]

Roxie plans on purchasing a new desktop computer for $1250. Which loan description would result in the smallest amount of interest she would have to pay?
12 months at 6.25% annual simple interest rate
18 months at 6.75% annual simple interest rate
24 months at 6.5% annual simple interest rate
30 months at 6.00% annual simple interest rate
Answer:
12 months at 6.25%
Step-by-step explanation:
You deposit $1250 into a bank account paying 6.25% simple interest per month. You left the money in for 12 months. Find the interest earned and the amount at the end of those 12 months?
Result:
The interest is $937.5 and the amount is $2187.5.
Explanation:
STEP 1: Convert interest rate of 6.25% per month into rate per year.
STEP 2: Convert 12 months into years.
STEP 3: Find an interest by using the formula , where I is interest, P is total principal, i is rate of interest per year, and t is total time in years.
In this examplee P = $1250, i = 75% and t = 1 years, so
STEP 4: Find an amount by using the formula .
Since P = $1250 and I = $937.5 we have
24 + 8x + 10(2x)

Answer:
CH = 6
BAH = 96
Step-by-step explanation:
BC = 12, so BK = 6, and ABK = ACH, so BK = CH = 6
BAK = 32, KAC = 32, CAH = 32
BAK + KAC + CAH = BAH = 96

The top of a tall building has four triangular faces that slope toward a single point. What shape best models the top
of the building?
А cube
c. triangular pyramid
B cone
Dsquare pyramid
Choose
Answer:
Option D, square pyramid
Step-by-step explanation:
The base of a square pyramid is a square of side of length "A"
and the height of the pyramid is "h"
From the four sides of base of pyramid, four surfaces arises that are slanting and meet at a point at the top at height "h"
Hence, option D is correct
Four times a first number decreased by a second number is 19. The first number increased by four times the second number is −8. Find the numbers.
Answer:
a = 4
b = -3
Step-by-step explanation:
Let a and b be the two numbers.
According to question,
4a - b = 19........(i)
And,
a + 4b = -8........(ii)
From (i),
4a - b = 19
or, b = 4a - 19
Replacing b in (ii),
a + 4(4a - 19) = -8
a + 16a - 76 = -8
17a = -8 + 76
17a = 68
a = 68/17
a = 4
And,
b = 4a - 19
= 4 x 4 - 19
= 16 - 19
= -3

Answer:
JK < KI < IJ
Step-by-step explanation:
The length of the side of a rectangle corresponds with the size of the angle opposite it.
m<K = 180 - (50 + 44) (sum of triangle)
m<K = 86°
IJ is opposite m<K = 86°
JK is opposite to m<1 = 44°
KI is opposite to m<J = 50°
The bigger the measure of an angle, the larger the side opposite it.
Therefore, form least to greatest, the side lengths of the triangle cam be ordered as follows:
JK < KI < IJ
