A meat seller bought 250kg of meat fo GHC 224 At what price per kg should he retail it in order to make proft of 25%
Answer:
GHC1.19
Step-by-step explanation:
Given data
Mass of meat= 250kg
Cost of meat= GHC 224
cost price per kg
=224/250
=GHC 0.896 per kg
% profit= selling-cost/selling*100
let the selling price be x
25= x- 0.896/x*100
0.25= x-0.896/x
cross multiply
0.25x=x- 0.896
0.25x-x= - 0.896
0.75x= 0.896
x= 0.896/0.75
x=GHC1.19

F is directly proportional to a.
If F = 28 when a = 7 find,
F when a = 10
Answer:
Step-by-step explanation:
a=10
Step-by-step explanation:
The question can be interpreted as
F∝a
If we introduce proportionality constant k, we have
F= k.a
28= k. 7
k= 28/7
k= 4
Then the equation can be written as
F= 4.a
To find, a when F = 40?
F= 4.a
40=4 × a
a= 40/4
a= 10
Answer:
F = 40
Step-by-step explanation:
Given F is directly proportional to a then the equation relating them is
F = ka ← k is the constant of proportion
To find k use the condition F = 28 when a = 7 , then
28 = 7k ( divide both sides by 7 )
4 = k
F = 4a ← equation of proportion
When a = 10, then
F = 4 × 10 = 40
Find the total surface area of this cuboid 4cm 2cm 5cm
Answer:
76cm²
Step-by-step explanation:
SA=2lw+2lh+2hw
length=4cm
width=2cm
height=5cm
= 2(4×2+4×5+5×2)
=8+20+10
=2×38
=76cm²
If the expression 76.56 is written as 6k, what is the value of k?
Answer:
6k=76.56
k = 12.76
Step-by-step explanation:
the total value of 76.56 is represented as 6k
this means we equate 6k to 76.56
i.e 6k = 76.56
dividing both sides by 6
we have, k = 12.76
A car that traveled 50 miles in 2 hours had the same average speed as a
car that traveled 200 miles in 8 hours. Is this true or false?
Answer:
True
Step-by-step explanation:
[tex]\frac{200 miles}{8 hours} = \frac{100miles}{4hours} = \frac{50miles}{2hours}[/tex]
What is the length of the hypotenuse?
Answer:
The answer is c = 17 feet
Step-by-step explanation:
The formula to find the hypotenuse is a^2 + b^2 = c^2 (a squared plus b squared equals c squared).
a = 8 feet
b = 15 feet
a^2 = 8 * 8 = 64
b^2 = 15 * 15 = 225
The next step is to add: 64 + 225 = 289
But we need to remember to square root 289 because we squared a and b.
The square root of 289 equals 17
c = 17 feet
Mia is collecting boxes to help her friend move. She found a box that is 4 ft. Wide, 3 ft. High, and 2 ft. Long. How much space would the box take up in the moving truck?
Answer: 24 ft³
Step-by-step explanation:
To calculate the amount of space that the box will take up in the moving truck, we are simply meant to calculate the volume. This will be:
= Length × Width × Height
= 2 × 4 × 3
= 24 ft³
Therefore, the space that the box will take up in the moving truck is 24 ft.

Daniella collected 4242 bushels of peas from her garden today. Tomorrow she will send \frac{3}{7} 7 3 of the peas to market. How many bushels will she KEEP?
Answer: 24
Step-by-step explanation:
Amount of bushels of peas collected = 42
Fraction that'll be sent to market = 3/7
Fraction that'll be kept = 1 - 3/7 = 7/7 - 3/7 = 4/7
The number of bushels that'll be kept will be:
= Fraction that'll be kept × Total number of bushels collected
= 4/7 × 42
= 24
Dolores spent $ 13.00 of the $20.00 in her wallet. Which decimal represents the fraction of the $20.00 Dolores spent?

A cube with a volume of 64 cubic meters is scaled by a factor of 5. What is the volume of the
modified cube in cubic meters? (Note: do not include the units in your answer.)
Clear
X Incorrect. When the sides of the cube are scaled by a factor of k = 5) the volume increases
by a factor of k = 52 = 125. Here, the new volume is 64 cubic meters 125 = 8,000 cubic
meters. Enter the correct answer
