Answer:
1135.38
Step-by-step explanation:
Original amount = 1015;
First decrease = 6%
Followed by an increase = 19%
Unknown:
Final amount:
Solution:
If 100% of a value implies multiplying by 1;
6% decrease = 0.94
19% increase = 1.19
Now;
Final amount = 1015 x 0.94 x 1.19 = 1135.38
Here are the percents of the popular

49.6, 55.1, 57.4, 49.7, 61.1, 43.4,
60.7, 50.1, 50.7, 58.8, 53.9, 43.2,
49.2, 47.9, 51.2
What is the median?
Ok, you should first order every number in the regular order (1,2,3,4,5,6,7,and so on) or (1.2,1.3,2.4,5.9).
43.2, 43.4, 47.9, 49.2, 49.6, 49.7, 50.1, 50.7, 51.2, 53.9, 55.1, 57.4, 58.8, 60.7, 61.1.
Median means the exact middle and here there are total of 15 different numbers so we know this is going to be easier if this was even. 50.7 is the median because it is in the middle and there are an even number of numbers on each side to it, 7.
Answer: just to make it clear for people
it is 50.7

Brad has $10 to spend at Ruby's. He orders 1/2 pound of sausage and 11/4 pound of chicken. How much money will Brad have left after he pays for his order?
Answer:
Step-by-step explanation:
Brad will have $5.24 left after he pays for his order.
What is unit rate?A unit rate means a rate for one of something. We write this as a ratio with a denominator of one. For example, if you ran 70 yards in 10 seconds, you ran on average 7 yards in 1 second. Both of the ratios, 70 yards in 10 seconds and 7 yards in 1 second, are rates, but the 7 yards in 1 second is a unit rate.
Given that, Brad has $10 to spend at Ruby's. He orders 1/2 pound of sausage and 11/4 pound of chicken.
Price of sausage per pound (unit rate) = $3.25
Therefore, price of 1/2 pounds of sausages = $3.25×0.25 = $1.63
Price of chicken per pound (unit rate) = $2.50
Therefore, price of 1 1/4 pounds of sausages = $2.50 × 1.25 = $3.13
Total the amount he spent at Ruby's = $1.63+$3.13 = $4.76
Amount left after payment = $10-$4.76
= $5.24
Hence, Brad will have $5.24 left after he pays for his order.

60°, 120°
40°, 140°
Answer:
75°, 105°
Step-by-step explanation:
Supplementary angles sum to 180°
Sum the parts of the ratio, 5 + 7 = 12 parts
Divide 180° by 12 to find the value of one part of the ratio.
180° ÷ 12 = 15° ← value of 1 part of the ratio, thus
5 parts = 5 × 15° = 75°
7 parts = 7 × 15° = 105°

Madison invested $3,300 in an account paying an interest rate of 6.7% compounded daily. Assuming no deposits or withdrawals are made, how much money, to the nearest ten dollars, would be in the account after 5 years?
Answer:4610
Step-by-step explanation:
$4564 is the amount in account after 5 years.
What is Percentage?percentage, a relative value indicating hundredth parts of any quantity.
Given that Madison invested $3,300 in an account paying an interest rate of 6.7% compounded daily.
We need to assume no deposits or withdrawals are made, then we need to find money in account after 5 years.
Madison invested = $ 3300
Rate of interest = 6.7 %
Time = 5 years
[tex]A=P(1+\frac{r}{100} )^{t}[/tex]
P is the principle amount
t is the time
r is the rate of interest
[tex]A=3300(1+\frac{6.7}{100} )^{5}[/tex]
A=3300(1+0.067)⁵
A=3300(1.067)⁵
A=3300(1.383)
A=4563.9
A=4564
Hence, $4564 is the amount in account after 5 years.

A cuboid with a volume of 925cm^3 has dimensions.
4cm, (x + 1) cm and (x + 11) cm.
Show clearly that x^2 + 12x - 220 = 0
Solve the equation by factorising, making sure you show the factorisation.
State both values of x on the same line.
Finally, find the dimensions of the cuboid, writing all three on one line.
Answer:
Step-by-step explanation:
Volume of the cuboid = Length * Width * Height
Given
Length = 4cm
Width = (x+1)cm
Height = (x-11)cm
Volume of the cuboid = 4(x+1)(x+11)
Volume of the cuboid = 4(x^2+11x+x+11)
Volume of the cuboid = 4(x^2+12x+11)
Volume of the cuboid = 4x*2+48x+44
925 = 4x*2+48x+44
4x*2+48x+44-925 = 0
4x*2+48x-881 = 0
Divide through by 4
x^2 + 12x - 220.25 = 0
Factorize using the general formula;
x = -12±√12²-4(-220.25)/2
x = -12±√144+881/2
x = -12±√1025/2
x = -12±32/2
x = 12+32/2
x = 20/2
x = 10
Hence the dimension of the cuboid is 4cm, (10+1)cm and (10+11)cm
Dimension is 4cm by 11cm by 21cm

Liberty bought a make-your-own salad when she went out to lunch at a restaurant. The salad cost $4, plus $0.85 for each salad topping. Liberty spent $9.95 on the salad. Which equation can be used to find t, the number of toppings that Liberty ordered on her salad
I believe you answer would be $4 + $0.85t =$9.95
Answer:
7
Step-by-step explanation:
c = $0.85t+$4
$9.95 = $0.85t+$4
$9.95-$4 = $0.85t
$5.95 = $0.85t
$5.95/$0.85 = t
7 = t

a line passes through 8,-8 and has a slope of -5/4, write an equation in slope intercept form for this line
Answer:
y = -1.25x +2
Step-by-step explanation:
Using Point-Slope formula we can create an equations.
y - y1 = m(x - x1)
substitute:
y + 8 =-5/4(x - 8)
-5/4 = -1.25
y + 8 = -1.25 ( x - 8)
Distribute:
y + 8 = -1.25x + 10
subtract 8 from both sides:
y = 1.25x + 2
