Answer:

48

Step-by-step explanation:

first, since its a rectangle, the parallel sides are equal making the top of the rectangle 9cm. the to fins the sides, we do 9+9( because of the sides o the rectangle) which gives us 18. then we need to do 28-18 to find out how much both the other sides of the rectangle are, which is 10. now we divide that by 2 since we want one for each side main the measurements for the rectangle are 9cm by 5 cm. now since to find out the area of aa trapezium, we use the formula   A=1/2(a+b)h which means we add the 2 parallel sides of the rectangle which are 5 and 9. we got the 9 from figuring out the rectangle remember? now 9+5=14. next we times it by the height which will be 6 since 11-5 is 6. we got the 5 from figuring out the rectangle above. now 14x6 is 84. however what about then 1/2 part in the formula?. well, all we do now is divide 84 by 2 which gives us 48

REMEMBER: The formulae for working out the area of a trapezium is 1/2x(a+b)xh

Over the last three evenings, Donna received a total of 129 phone calls at the call center. The third evening, she received 3 ti
lakkis [162]

Answer:

Number of calls received in 1st evening = 24

Number of calls received in 2nd evening = 33

Number of calls received in 3rd evening = 72

Step-by-step explanation:

Let

number of calls received in first evening be "x"

number of calls received in 2nd evening be "y"

number of calls received in 3rd evening be "z"

Total, in 3 evenings, we have 129 phone calls, so we can write:

x + y + z = 129

3rd evening, 3 times as first evening. We can write:

z = 3x

2nd evening, 9 MORE THAN FIRST. So we can write:

y = 9 + x

Now we replace 2nd and 3rd equation in 1st equation to get:

x + y + z = 129

x + 9 + x + 3x = 129

Now, first, we solve for x:

x + 9 + x + 3x = 129\\5x+9=129\\5x=120\\x=24

Solving for y:

y = 9 + x

y = 9 + 24

y = 33

Solving for z:

z = 3x

z = 3(24)

z = 72

Thus,

Number of calls received in 1st evening = 24

Number of calls received in 2nd evening = 33

Number of calls received in 3rd evening = 72

Solve for x.<br> Help please(:
Anit [1.1K]

Answer:

x = 10°

Step-by-step explanation:

As we can see it is an equilateral triangle so all sides and angles are equal.

6x + 6x + 6x = 180° { being sum of angles of triangle }

18x = 180°

x = 180° / 18

x = 10°

Hope it will help ✔
