Answer:
Dylan should receive £75
Step-by-step explanation:
We know that
Abby, Neil, and Dylan share money in the ratios 2:4:5
This means that for every £2 that Abby has, Neil has £4, and Dylan has £5.
From this, we also know that for every £4 that Neil has, Dylan has £5.
Now we know that Neil receives £60
For each group of £4, Dylan will have £5.
Then we need to count how many times £4 is on £60, this is equal to:
£60/£4 = 15
And for each one of these, Dylan should receive £5, this is:
15*£5 = £75

Y= -8x + 10/9 what is the y intercept
Answer:
10/9
Step-by-step explanation:
This equation is in slope-intercept form, this is referring to the y-intercept. Slope-intercept is y=mx+b, where m is the slope and b is the y-intercept. Therefore, 10/9 is the intercept while -8 is the slope.
Find f (-12) if f (x) = -12x + 100
f(-12) = -12(-12) + 100 = 144 + 100 = 244
Answer:
244
Step-by-step explanation:
Substitute -12 as x.
f (-12) = -12(-12) + 100
f (-12) = 144 + 100
f (-12) = 244

Explain the steps of graphing 2x + 4≤ 12.
Answer:
Step-by-step explanation:
First, you want to simplify so the equation would be x+2≤6 or x≤4
Because you are solving for x you want to graph a vertical line on 4.
Then you shade on the left side of the line because it is less than or equal to. If it were just less then you would do a dashed line on 4 but because it is also equal to 4 then you keep it a solid line.
I recommend using Desmos graphing calculator.

Cupid's arrow travels 45 meters in 5
seconds. What is the speed of the
flying arrow?
Answer:9
Step-by-step explanation:
45/5 =9
s=d/t
The speed of the flying arrow will be 9 meters/second.
What is the relation between speed and distance?Speed describes how accelerated something or somebody is moving. If you know the distance traveled and the time it took, we can calculate the average speed of an object.
The speed formula is speed = distance/time.
We are given that Cupid's arrow travels 45 meters in 5 seconds.
Therefore, distance = 45 meters
Time= 5 seconds.
Thus, speed = distance/time
Speed = 45/5
Speed =9

Find the surface area.
13.5 in
9 In
9 in.
10 in.
the surface area of the body is approximately 739.72 square inches. first find the area of the two triangles (base and top) using Heron's formula
what is surface area ?
Surface area is the total area of all the faces or surfaces of a three-dimensional object. It is the sum of the areas of all the faces of the object, including the top, bottom, and sides. Surface area is usually measured in square units, such as square inches or square meters.
In the given question,
Let's first find the area of the two triangles (base and top) using Heron's formula:
For the base triangle with side lengths 9, 10, and 13.5:
s = (9 + 10 + 13.5)/2 = 16.25
Area = √(s(s-9)(s-10)(s-13.5)) = 35.44 square inches
For the top triangle, the side lengths are the same, so the area is also 35.44 square inches.
Now, let's find the area of the four sides. We can divide the body into two trapezoids and two triangles. The trapezoids have heights of 9 inches and bases of 9 and 10 inches. The triangles have a base of 13.5 inches and a height of the slant height of the trapezoid, which we can find using the Pythagorean theorem:
h = √(13.5² - (10-9)²) = √(146.25) = 12.1 inches
So, the area of each trapezoid is:
(9/2)*(9+10)*√(146.25 - 9.5²) = 252.28 square inches
And the area of each triangle is:
(1/2)13.512.1 = 81.94 square inches
Finally, the total surface area is the sum of all these areas:
35.44 + 35.44 + 252.28 + 252.28 + 81.94 + 81.94 = 739.72 square inches
Therefore, the surface area of the body is approximately 739.72 square inches.

Consider the table shown above. What is the value of f(g(3)) ?
Answer: D-8
Step-by-step explanation:
6+2
The value of f(5), according to the provided table, is 5.
Evaluation of Functions:Evaluating a function means finding the value of an input inserted in a certain function. The input is the domain of the function, and the result is the range of the function. The domain is represented by the x-axis and the range is represented by the y-axis when a function is graphed.
The function f(g(x)) is called a composite function because it is made of two functions. For composite functions, the final value is obtained by performing two steps. The first step is finding the value of the function on the inside. Then, the value of the inside function is used, and the outer function is calculated for that value. So we first have to find the value of g(3), meaning that x is equal to 3.
According to the provided table for the values of x and g(x), when the value of x is 3, the value of g(x) is 6. This is the first step. The subsequent step is finding the value of the f(x) function. The x of this function is the value of g(x), which is 6. The value of f(5), according to the provided table, is 5.

A line is parallel to y = 4x + 1 and
intersects the point (-2,-5). What is the
equation of this parallel line?
y = [?]x + [
Answer:
y = 4x+3
Step-by-step explanation:
The equation in point slope form is expressed as y - y0 = m(x-x0)
m is the slope
(x0, y0) is the point on the line
If a line is parallel to y = 4x + 1, the slope of the line m = 4
Substitute m = 4 and the point (-2, -5) into the equation above;
y - (-5) = 4(x - (-2))
y+5 = 4(x+2)
y+5 = 4x+8
y = 4x+8-5
y = 4x + 3
Hence the equation of the line is y = 4x+3

The sum of 6.7 and a number is negative. What is a possible value for that number? Explain.
Answer:
The number must be greater than 6.7. Thus, the sum will be negative.
For example, the number could be 7.
6.7 - 7 = -0.3
The number can be in the range - x ∈ (- ∞ , - 6.7)
We have - the sum of 6.7 and a number is negative.
We have to determine the possible value of that number.
For what range of values of x, the given function is equals to a negative value -y = f(x) = 2x + 10For f(x) to be negative -
f(x) < 0
2x + 10 < 0
2x < - 10
x < - 5
x ∈ (- ∞ , - 5)
According to the question, we have - the sum of 6.7 and a number is negative.
Now -
6.7 + x < 0
x < 6.7
x ∈ (- ∞ , - 6.7)
Hence, the number can be in the range - x ∈ (- ∞ , - 6.7).
