Answer:
Jumper costs £13
Step-by-step explanation: (s = shirt j = jumper)
We know that 2s + 1j = £29
We also know that 1s + 1j = £21
29-21 = £8
This means that the shirts cost £8 each
We now need to multiply: 8 x 2 = £16 which means that the shirts in total cost £16
So, 29 - 16 = £13 which means one jumper costs £13
The cost of one jumper is $13.
What is an equation?An equation is a mathematical statement that shows that two mathematical expressions are equal.
Given that, two shirts and one jumper cost £29 while one shirt and one jumper cost £21, we need to find the cost of one jumper,
Let jumper is represented by j and that of shirt by s,
Establishing the equations,
2s + j = 29
j = 29 - 2s......(i)
s + j = 21
j = 21 - s.......(ii)
Solving the equations,
21 - s = 29 - 2s
s = 8
Put s = 8 in eq (ii)
j = 21 - 8
j = 13
Hence, the cost of one jumper is $13.

Jonathan is putting a border around a right triangle and needs to figure out the triangle's height. If the triangle has a base length of 4 cm and a total area of 24 cm², what is the height?
Step-by-step explanation:
formula to find area of a triangle:
A=1/2 × base × height(h)
insert the values into the formula:
24=1/2 × 4 × h
solve for h :
24=2h
24/2=h
h = 12 cm ( Ans )
The height of triangle will be 12 cm.
What is mean by Triangle?A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.
Given that;
The triangle has a base length of 4 cm.
And, A total area of 24 cm².
Now,
We know that;
Area of right triangle = 1/2 × Base × Height
⇒ 24 = 1/2 × 4 × h
⇒ 24 = 2 × h
⇒ h = 24 / 2
⇒ h = 12 cm
Thus, The height of triangle = 12 cm.

Answer:
a = 84°
b = 36°
c = 24°
d = 84°
e = 132°
Step-by-step explanation:
The parameters of the workers in the office are;
The number of staffs in the office = 60 staffs
The take-aways are pizza, curry, fish & chips, kebab and other
The frequency for the above take-aways = 14, 6, 4, 14, and 22 respectively
The variables for the angles representing the above take-aways on the pie chart = 'a', 'b', 'c', 'd', and 'e'; respectively
In order to find the size of the angles that represent each group of workers in the pie chart, we find the ratio of the group size to the total number of workers and we multiply the result by 360° as follows;
∠a = 360° × 14/60 = 84°
∠b = 360° × 6/60 = 36°
∠c = 360° × 4/60 = 24°
∠d = 360° × 14/60 = 84°
∠e = 360° × 22/60 = 132°

Allison ordered 7 pictures.
what was the original weight of the ball ?
Answer:
16.5
Step-by-step explanation:
A is the correct answer
Step-by-step explanation:
If you plug y=x+10 in for the Y variable you just have to solve by multiplying.
1.) It should look like this:
2x + 3(x +10) = 40
2.) You will distribute the three which will make the equation look like this:
2x + 3x + 30 = 40
3.) Add like terms. Then subtract 30 from both sides. Then divide 5 by both sides to get the variable x alone.
but 16.5 is the answer
A smartphone has a screen that has a width of x and a height that is 1.8 times the width. The outer dimensions of the phone are shown.
Write an expression for the portion of the phone that is not occupied by the screen. Assume that the phone is rectangular.
Answer: 4.8x+3
Step-by-step explanation:
The portion of the phone that is not occupied by the screen is 4.9x + 3 cm².
What is Surface Area?For each three-dimensional geometrical shape, surface area and volume are determined. The area or region that an object's surface occupies is known as its surface area. Volume, on the other hand, refers to how much room an object has. There are numerous shapes and dimensions in geometry, including sphere, cube, cuboid, cone, cylinder, etc. Each form has its own volume and surface area. Nevertheless, we can only estimate the area that two-dimensional figures like a square, circle, rectangle, triangle, etc. cover; there is no volume available.
As per the given data:
The width of the screen = x cm
Height of the screen = 1.9 times the width = 1.9x
Dimensions of the phone are given in the diagram.
The area of the screen = height × width
= 1.9x × x = 1.9x² cm²
The area of the phone = (1.9x + 3)(x + 1)
= 1.9x² + 1.9x + 3x + 3
= 1.9x² + 4.9x + 3 cm²
Area of the phone not occupied by screen:
= area of the phone - area of the screen
= 1.9x² + 4.9x + 3 - 1.9x²
= 4.9x + 3 cm²
Hence, the portion of the phone that is not occupied by the screen is 4.9x + 3 cm².

Step 1: Find out how many pens he bought
12 pens per pack
Charles bought 60 packs
60 packs x 12 pens = 720 pens
Step 2: Find out how much Charles spent
2.80 per pack
Charles bought 60 packs
60 x 2.80 = 168 pounds
