Answer:
16
Step-by-step explanation:
1st group = 30% or .3 as a decimal
.3 * 40 = 12
2nd group = ate 7
Third group = 1/8 or .125 as a decimal
.125 * 20 = 5

There are 18 football teams in a league. each team plays two match against each of the teams work out the total number of matches played
Answer:
34 matches
Step-by-step explanation:
Given
Total football team = 18footbal teams
This means that each team will play 17 other teams. This is equivalent to 17matches for each team in the first match round.
This can be expressed as;
17matches = 1 round
To get the total number of matches played if each team plays two match against each of the team, then;
x matches = 2rounds
Divide both expression
17/x = 1/2
Cross multiply
x * 1 = 17 * 2
x = 34
Hence the total number of matches played is 34 matches

Suppose you have:
u = 2f + 14
f = 4x - 4x²
What is u in terms of x?
put the whole thing after f = in the first equation
so
x^2 means x squared
so
u = 2 (4x - 4x^2) + 14
so
u = 8x - 8x^2 + 14

Find the slope of the line that passes through the points (–4, 2) and (6, 6).
Answer:
Step-by-step explanation:
point P1 (-4,-2) in the form (x1,y1)
point P2(6,6) in the form (x2,y2)
slope = m
m = (y2-y1) / (x2-x1)
copy and paste the above formula into word pad on your computer for any problem asking about slope :)
m = [ 6-(-2) ] / [ 6-(-4) ]
m = [ 6+2 ] / [ 6+4 ]
m = 8 / 10
m = 4/5
The required slope of the line is 4/5 which passes through the points (–4, 2) and (6, 6).
What is the slope of the line?The slope of line is defined as the angle of the line. It is denoted by m
Slope m = (y₂ - y₁)/(x₂ -x₁ )
The given Line passes through the points (–4, 2) and (6, 6).
Let
x₁ = -4, y₁ = 2
x₂ = 6, y₂ = 6
∵ Slope m = (y₂ - y₁)/(x₂ -x₁ )
Substitute the values in the above formula and solve for m
m = [ 6-(-2) ] / [ 6-(-4) ]
m = [ 6+2 ] / [ 6+4 ]
m = 8 / 10
Reduce the fraction into a simplest form,
m = 4/5
Thus, the required slope of the line is 4/5 which passes through the points (–4, 2) and (6, 6).

write the ratio for
14:56
key words
answer=Ans
I don’t really get your question but I can kinda imagine what questions you are asking. Pls look at these Q and A and see which one you need
1, How to simplify this ratio: When you are simplifying a ratio it is kinda the same of simplifying a fraction. For example we have the ratio 2:4 There is two ways to simplifying this ratio. First way is to make this ratio into a fraction then simplifying the fraction so 2:4= 2/4. know all you need to do is simplfly 2/4 and then changing it back to a ratio. the second way is to simplifly it as a ratio. 2:4, think about what number can you divide them both by. Which is 2. The Ans. Would be 1:2.
2. How to find a ratio that is equivalent to this ratio?. Finding a ratio equivalent to this ratio you can multiply or divide. you can’t minus or add. So let’ just say I want to find a equivalent ratio to 4:7. For this you can) divide is so then we have to multiply it. So let’s multiply this by 2. 4x2=8 and 7x2=14. So the equivalent ratio to this could be 8:14 or 12:21. Their could be more equipment ratio. As for dividing, I have the ratio 5:25, like how to simplifying a ratio you find a number that can divide it by which is five. 5/5=1 and 25/5=5. So the equivalent ratio to this is 1:5.
hope this helps

A living room will be painted with white trim. The ratio of the blue surface area between the walls is 1:10. Of 2 gallons of blue paint are used for the walls , how many pints of white pant do we need for the trim
Answer:
20 gallons
Step-by-step explanation:
The living room is made up of white trim and blue surface area between the walls. Since the ratio of the blue surface area between the walls to the white trim is given by 1 : 10.
Also 2 gallons of blue paints are used for the walls, let x represent the number of white paint used in gallons. Hence:
number of white paint in gallons = [1 / (1 + 10)] * total number of paints = 1 / 11 * total number of paints
2 = 1/11 * total number of paints used
total number of paints = 22 gallons
number of white paint (x) = [10 / (1 + 10)] * total number of paints = 1 / 11 * total number of paints
x = 10/11 * 22
x = 20 gallons
Therefore 20 gallons of white paint was used

Find the volume of the composite solid. Round your answer to the nearest hundredth. A composite shape consisting of a semi-cylinder placed atop a cube. The sides of the cube are labeled 4 inches. Find the volume of the composite solid. Round your answer to the nearest hundredth. A composite shape consisting of a semi-cylinder placed atop a cube. The sides of the cube are labeled 4 inches.
Answer:
89.14 in.³
Step-by-step explanation:
A semi-cylinder is half of a cylinder. A cube has equal sides. So if it is placed on top a cube, the following dimensions can be deduced:
The length of one side of the cube (s) = the diameter (d) of the semi-cylinder and also the height (h) of the semi-cylinder
Length of one side of the cube = 4 in.
Therefore,
Diameter of semi-cylinder = 4 in.
radius (r) = ½(4) = 2 in.
Height (h) of semi-cylinder = 4 in.
Let's find the volume of the composite solid
Volume of the composite solid = volume of semi-cylinder + volume of cube
= ½(π*r²*h) + (s³)
Volume of composite solid = ½(π*2²*4) + (4³)
= ½(50.27) + 64
= 89.135
≈ 89.14 in.³ (nearest hundredth)

Lucy asked 5 friends how many books they each read last month. She put her data in a table and found the total books read.
Answer:
answer would be A. The median is 3, is greater than the mean 2.
Step-by-step explanation:
the medial is 3 because it is in the middle while the mean is 2 because you add all them up and divide how many people there are. So 10 divided by 5 is 2.
