If shirt cost $21 last month and the price decreased by 30% then the new price is $14.7.
What is Percentage?percentage, a relative value indicating hundredth parts of any quantity.
Given that a shirt cost is $21 last month.
The price decreased by 30% in this month.
We have to find the new price.
To find this we have to find 30 percentage of 21.
Convert 30 % to decimal value by dividing with 100 and then multiply the decimal value with $21.
30/100× 21
0.3×21
$6.3
So the amount decreased is $6.3
The new price we get by subtraction $6.3 from $21.
21-6.3
New price = $14.7
Hence, if shirt cost $21 last month and the price decreased by 30% then the new price is $14.7.

There are 280 pieces of fruit in a fruit salad. There are twice as many raspberries as blueberries, three times as many grapes as cherries, and four times as many cherries as raspberries. How many cherries are there in the fruit salad?
Answer:
64 cherries
Step-by-step explanation:
Given that
There are 280 pieces of fruit in a fruit salad
There are twice as many raspberries as blueberries,
three times as many grapes as cherries,
and four times as many cherries as raspberries
We need to find out the number of cherries in the fruit salad
So,
Let us assume the blueberries be x
So, the raspberries be 2x
Cherries be 8x
And, grapes be 24x
Now
x + 2x + 24x + 8x = 280
35x = 280
x = 8
hence, the No of cherries in the salad
= 8 x
= 8(8)
= 64 cherries

solve the system of equations 9x-9y=-9 and 4x-3y=-8 by combining the equations PLEASE HELP QUICKLY!!!!!
9x-9y=-9
x-y=-9/9
x-y+1=0.......(1)
4x-3y=-8
4x-3y+8=0....(2)
combining equation we get
(x-y+1)(4x-3y+8)=0
x(4x-3y+8)-y(4x-3y+8)+4x-3y+8=0
4x²-3xy+8x-4xy+3y²-8y+4x-3y+8=0

On the line that passes through point C, mark a point D that is distinct from point C. Use the slope formula along with coordinates of points to find the slopes of and . Show your work.
Answer:
PLATO
Step-by-step explanation:
Answer:
The coordinates of point D will vary based on the point location, but the resulting slope of the line through points C and D will be the same.
A = (-3, 3), B = (-1,-1)
Slope of AB = (YB−YA) / ( XB –XA) =−1−3 / −1−(−3)= − 4 / 2= −2
D = (-1,6), C = (1,2)
Slope of DC = (YC−YD) / (XC−XD)= 2 – 6 / 1−(−1)=−4 / 2=−2

C/d = π = 3.14Same result comes from the tableCorrect choice is B#2Sum of angles of a triangle is 180°
m∠A + m∠B + m∠C = 180°A and C are equal angles as opposite sides are congruent.

Answer: $258.40
Step-by-step explanation:
The formula to calculate the simple interest will be:.
= Principal × Rate × Time
where,
Principal = $3400
Rate = 1.9%
Time = 4
Interest = $3400 × 1.9% × 4
= $3400 × 0.019 × 4
= $258.40

The volume of gas varies inversely with the pressure exerted. If the volume is 3.5 liters when the pressue is 5, find the volume wihen the pressure is 8.
Answer:
v = k/p
where k is constant
3.5 = k/5
k = 3.5 × 5
k = 17.5
v = 17.5/p
v= 17.5/8
v = 2.1875
v ≈ 2.20 litres
