£60 is divided between Richard, Stephen & Bridget so that Richard gets twice as much as Stephen, and Stephen gets three times as much as Bridget. How much does Richard get?
Answer: £18
Step-by-step explanation:
let Bridget get £x,
Stephen gets 3x, Richard gets 2(3x)
Equation is x + 3x + 6x = 60
10x = 60: x = 60/40 = 6
Bridget gets £6
Stephen gets 3x = 3 x 6 = £18
Richard gets 2(3x) = 2 x 18 = £36

On a soccer team 40% of the goal are scored by a star player on the team.If 70 goals were scored all season, how many are scored by the rest of the team? Plz help me
Answer:
42
Step-by-step explanation:
During the season, 40% of the goals are scored the by the star player. This means that 60% of the goals are scored by everyone else.
100% - 40% = 60%
To find how many goals are scored by the rest of the team, convert the percentage to a decimal. You then have to multiply the decimal by the total goals scored.
60% = 0.6
70 × 0.6 = 42
The rest of the team scored 42 goals.
Answer:
42
Step-by-step explanation:
40% of 70=28
70-28=42
The diagram shows a cuboid.
6 cm
The height of the cuboid is 6 cm.
The volume of the cuboid is 90 cm.
What is the area of the shaded face?
Answer:
length x width x 6 = 90
area of shaded face = 15
The area of the shaded region is 15 square cm.
What is area?
The space occupied by a flat shape or the surface of an object is called area.
Formula for the area of rectangle[tex]Area = lb[/tex]
Where,
l is the length of the rectangle.
b is the breadth of the rectangle.
What is volume?A volume is simply defined as the amount of space occupied by any three-dimensional solid.
Formula for volume of cuboidvolume = length × breadth × height
According to the given question.
We have,
Height of the cuboid = 6cm
Volume of the cuboid = 90 cubic cm.
⇒ length × breadth × height = 90
⇒ length × breadth × 6 = 90
⇒ length × breadth = [tex]\frac{90cm^{2} }{6cm}[/tex]
⇒ length × breadth = 15 square cm....(i)
Since, the area of shaded region = length × breadth
From (i)
Length × breadth = 15 square cm .
Hence, the area of the shaded region is 15 square cm.

Describe a way that you can remember the elements of the reflection matrices if you forget where the 1s, -1s, and 0s belong.
Answer:
Associate the numbers or coordinates with something in your life. Think of it from every possible aspect. For example, number 7. I just think of it as "7 is half of 14, there are 7 days in a week, 7 can be said as 70, which means 7 tea cups. See like that, now when you try and remember the numbers, you are able to pick up on these trail of thoughts are trace it back to its origin, which here is 7.
Answer:
Multiplying the vertex matrix with the matrix gives us a reflection matrix. The most common matrix reflections are seen as a reflection in the x-axis as well as reflection in the y-axis. It can also be reflected by 90 degrees or by 180 degrees. So, one way to remember the elements is by multiplying the given matrix by a unit matrix. And on the other hand, you can remember the elements remembering by what degree we are reflecting the matrix. This way makes it easier to remember the elements.

Daredevil Danny was cliff jumping. He jumped off a cliff that was 14.2 meters above the surface of the
water. At the end of his jump, Danny was 2.3 meters below the surface of the water.
The following equation describes this situation
14.2 + (-16,5) = -23
What does -16.5 tell us?
Answer:
AnSwEr Is C
Step-by-step explanation:
in khAN
The value -16.5 tells us the displacement between his current position and his initial position.
What is displacement?Displacement is defined as the minimum distance between two points. It is a vector quantity and needs direction with magnitude.
It is given that
Initial position =14.2 m
Final position=-2.3 m
14.2+(16.5)=-2.3
To understand this, we need to first calculate the displacement between his initial and final position
Displacement = Final pposition - Initial position
Displacement= -2.3-14.2
Displacement =-16.5 m
So: -16.5m is the total displacement from the start position (i.e. off the cliff) and current position (beneath the water surface)

Hevesh wants to make 2 lines of dominoes that are both 21 inches long. Each line has dominoes spaced 1 and 1/2 inches apart. How many dominoes will she need for both lines?
Answer: 30 dominoes in total.
Step-by-step explanation:
Each line is 21 inches long.
the space between dominoes is 1 + 1/2 inches.
(assuming that the distance includes the domino itself) Now, we need at least two dominoes to see this distance,
The we have N + 1 dominoes per line, and the distance is:
N*(1 + 1/2)inches = 21 inches
If we find N, we can find the number of domineoes in each line:
N = 21/(1 + 1/2) = 14
This means that we have 14 + 1 = 15 dominoes in each line, and we have two lines, so we have 30 dominoes in total.

Henry was playing with his marble collection, and decided to challenge his friend Andrew to figure out how many of each color marbles he had. Henry gave Andrew the following clues. "I have x blue marbles. I have four times as many red marbles as blue marbles. I have 5 less green marbles then I do blue marbles." Altogether I have 91 marbles. How many green marbles does Henry have?
Answer:
11
Step-by-step explanation:
First, set up an equation. Since all the blue marbles+red marbles+green marbles= total number of marbles, we have: x+4x+x-5=91.
x+4x+x-5=91
6x-5=91
6x=96
x=16
Since there are x-5 green marbles, we get the number of green marbles=16-5=11.

Answer:
800
Step-by-step explanation:
900-100= 800
Therefore, the difference is 800. I hope this helps, have a great day!!!
Answer:
800
Explanation:
When solving this problem we need to remember that it is asking us to find how much money she gained throughout the day, NOT the total amount she had at the end of the day. To find how much money she gained, simply subtract one hundred by nine hundred.
900 - 100
800
Therefore, $800 was the change in how much money she had.
- B is the midpoint of line segment AC. If AB = 3x - 8 and BC = x + 12, find the value of x.
Answer:
x = 10
Step-by-step explanation:
Since B is the midpoint of segment AC, then AB = BC.
AB = BC
3x - 8 = x + 12
2x - 8 = 12
2x = 20
x = 10
As per the given information, the value of x is 10. For understanding, check the calculations provided below.
MidpointA midpoint is a point that divides a line into two parts equally.
In the given diagram,
B is the midpoint of line segment AC. Midpoint B divides the line segment AC equally.
When a midpoint B divides equally then AB = BC
Given that,
AB = 3x-8 and BC = x+12
B is the midpoint of line segment AC.
So,
AB = BC
Substitute the expression and solve for x
AB = BC
3x-8=x+12
Subtract x,
⇒ 3x-x-8 = x-x+12
⇒ 2x-8=12
Add 8
⇒ 2x = 12+8
⇒ 2x = 20
divide by 2
∵ x = 10
Thus, the value of x is 10.

Step-by-step explanation:
First let's expand the function h:
[tex]h = -16(t- 1/4)^2 + 49[/tex]
[tex]h = -16(t^2 - t/2 + 1/16) + 49[/tex]
[tex]h = -16t^2 + 8t - 1 + 49[/tex]
[tex]h = -16t^2 + 8t + 48[/tex]
To find when the marshmallow reaches the maximum height, we can use the formula to find the vertex of the quadratic function, and the x-coordinate of the vertex is when we have the maximum height:
[tex]x_{vertex} = -b/2a[/tex]
In our equation, b = 8 and a = -16, so:

Answer:
The width is x+4
Step-by-step explanation:
A = l*w
x^2+11x+28 = (x+7) *w
Factor the left side
(x+7)(x+4) = (x+7) *w
Divide each side by (x+7)
x+4 = w
The width is x+4
Answer:
x+4
Step-by-step explanation:
x^2+11x+28
x²+7x+4x+28
x(x+7)+4(x+7)
(x+7) (x+4)
area =l * w
l=(x+7)

Answer:
150°
Step-by-step explanation:
to find the individual angle of a REGULAR dodecagon (which means that all sides are equal), you'd use the equation I(individual angle)= (n-2)×180/n
N is number of sides. The number of sides on a dodecagon is 12. So, substitute N for 12
I= (12-2)×180/12 which simplifies to 10×180/12
10×180= 1800
1800/12 = 150
so, an individual interior angle of a dodecagon is 150°
