Ben is paid £12.50 per hour.
If he works for more than 7 hours in a day, he is paid overtime for the additional hours at a rate of 1.4 times his normal rate of pay.
Yesterday, Ben worked for 9 hours.
How much money did he earn?
Answer:
157,9 pounds
Step-by-step explanation:
we know that he earn 12,50 per hour and that more than 7 hour of work he earn x 1,4 than the normal.
1- 12,5 x 1,4= 17,5
2- 17,5 x 9 = 157,5

Find the area of the following shape:
Answer:
19 cm²
Step-by-step explanation:
→ Work out the area of the rectangle
1 × 7 = 7
→ State the formula for the area of the triangle
0.5 × base × height
→ Find the base and height
Base = 3 and height = 8
→ Substitute values into formula
0.5 × 3 × 8 = 12
→ Add this total to the rectangle formula
12 + 7 = 19 cm²

Hello!
10*17 = > 170 cm²
(3,14 * 8)/4 =>6,28cm²
170 + 6,28 => 176,28cm²
Answer:
182.56
Step-by-step explanation:
Area of the rectangle = 10 * 17 = 170cm^2
Area of Circle = 8 * 2 * [tex]\pi[/tex] * 1/4
=> 12.56
=> 170 + 12.56

Work out the perimeter of this shape.
Answer: 72.6 cm
Step-by-step explanation:
Data: the length of the sides we know=13 cm, 16 cm 7.3 cm, 5.7 cm, 6.2 cm
The length of the side in the middle=x
The perimeter of the shape=x
Step one, Find the length of the missing side by adding then subtracting
5.7+6.2=11.9
16-11.9=4.1
x=4.1 cm
Reason: If you want to find the missing side, we know that the entire side down there is 16 cm so we just add 5.7 to 6.2 to get 11.9 and the amount of cm left after subtracting 11.9 from 16 will be the length(l) of the missing side.
Step two, add up all the sides
13+13+16+7.3+7.3+4.1+5.7+6.2=72.6
Reason: To find the perimiter of a shape, you add up all the sides and since we have all of the sides(some sides appear twice) we can just add them all together for the answer.
Also, don't forget the 'cm' in the answer
x=72.6 cm

Answer:19 would be 79 because you would do 8 plus itself 7 times which would be like 8*7 which is 56 so 56+23 is 79 im not sure what 18 is because im not sure if its x*2 or x^2 but 20 would just be 38/4 which is 9.5 so the answer for 20 is that Becca makes $9.5 dollars an hour.

How do I solve this?
Answer:
Step-by-step explanation:
First, let's find the area of the triangle. The Area of a triangle can be modeled as
b x h x 1/2; base = 6 and the height equals 8. 6x8=48 then don't forget to divide by 2. 48/2= 24
To find the area of a half-circle, you first need to find the area of the whole circle. Whole circle area equation = r^2 times pi. The diameter is 8 and the radius is 1/2 times the diameter, therefore the radius = 4. 4^2= 16
16pi= approximately 50.24
50.24/2= 25.12
25.12 + 16 = 41.12
The area of the figure is approximately 41.12 ft^2
Hope this helps and please mark me brainliest, it really helps!
:)
Answer:
49.12 ft²
Step-by-step explanation:
The compound figure includes both a right angled triangle and a semi-circle. To find the area of the figure, it is best to find the area of both shapes then add them.
Area of semi-circle = (πr²) ÷ 2
= (3.14 × 4 × 4) ÷ 2
= 50.24 ÷ 2
= 25.12 ft²
Area of triangle = [tex]\frac{1}{2}[/tex]bh
= [tex]\frac{1}{2}[/tex] × 6 × 8
= 24 ft²
Area of compound figure = Area of semi-circle + Area of triangle
= 25.12 + 24
= 49.12 ft²
6 cars 4 people in each car HELP I HAVE 3 minutes
Answer:
Here we have 6 cars.
And we know that there are 4 people in each car.
The question is incomplete, I assume that we want to find the total number of people in the 6 cars.
So, again, there are 6 cars, and 4 people in each one.
Then we have 6 times 4 people.
This is equal to the product between 6 and 4, which is:
6*4 = 24
There is a total of 24 people in the 6 cars.

What’s the value of x?
G
53°
45
H
x°
Answer:
x = 98°
Step-by-step explanation:
95 + 53 + (180 - x) = 180
148 + 180 - x = 180
328 - x = 180
328 - x + x = 180 + x
x + 180 = 328
x + 180 - 180 = 328 - 180
x = 98°
The required measure of the remote exterior angle x is 98°.
Given that,
A triangle has shown,
Where two remote interior angles with measures 45° and 53° are given and a remote exterior angle with measure x is given, we have to determine the value of x.
The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
What is the angle?The orientation of one line with respect to the horizontal or other respective line is known as a measure of orientation and this measure is known as the angle.
Here,
There is a property of a triangle that, the sum of the remote interior angle is equal to the measure of the remote exterior angle. So,
x = 53 + 45
x = 98°
Thus, the required measure of the remote exterior angle x is 98°.

Given that HCF (306,657) = 9, find LCM (306,657)
Answer:
The LCM of 306 and 657 is 22338
Step-by-step explanation:
We know that
HCF (a, b) × LCM (a, b) = a × b
⇒ HCF (306, 657) x LCM (306, 657) = 306 × 657
⇒ 9 × LCM = 306 × 657
⇒ LCM (306, 657) = 306 × 657 / 9
= 201042 / 9
∴ LCM = 22338
Thus, the LCM of 306 and 657 is 22338.

if f(x)= 10 – 2x and g(x) = 6x - 5, then (f+g)(x) =
Answer:
4x +5
Step-by-step explanation:
f(x)= 10 – 2x
g(x) = 6x - 5
(f+g)(x) =10 – 2x + 6x - 5
Combine like terms
= 4x +5
Answer:
( f + g )( x ) = 4 x + 5
Step-by-step explanation:
f ( x ) = 10 - 2 x
g ( x ) = 6 x - 5
( f + g )( x) = ( (10 - 2 x ) + (6 x -5) )
= 10 - 2x + 6 x - 5

4.2 To buy a new car is not a very good investment. In the first year the car will
decrease in value by 25%.
4.2.1
If the car costs R200 000, what will it be worth after 1 year?
Given:
In the first year, the car will decrease in value by 25%.
The cost of a car is Rs. 200,000.
To find:
The worth of the car after 1 year.
Solution:
The cost of a car is Rs. 200,000 and in the first year the car will decrease in value by 25%. So, the worth of the car after 1 year is:
[tex]Worth=200000-\dfrac{25}{100}\times 200000[/tex]
[tex]Worth=200000-\dfrac{1}{4}\times 200000[/tex]
[tex]Worth=200000-50000[/tex]
[tex]Worth=150000[/tex]
Therefore, the worth of the car after 1 year is Rs. 150,000.
