a) Work out the value of 5^2 – 1^5× 2^4
b) Work out the value of 7^2 + 4^3 ÷ 2^5

Answers

First you have to know BODMAS/BIDMAS (idk if all schools teach it like this) but this is the order in which you complete questions so it’s Brackets, Indices, Division/Multiplication, Addition/Subtraction
a) 5^2 is 5x5 which equals 25 1 to the power of anything is always 1 and 2^4 is 2x2x2x2 which is 16
So 5^2-1^5x2^4 = 25-1x16 which is then 25-16 = 9
b) 7^2+4^3 divided by 2^5 so 7^2 is 7x7 which = 49 then 4^3 means 4x4x4 = 64 and 2^5 is 2x2x2x2x2 which equals 32 so
7^2+4^3 divides by 2^5 is 49+64/32 = 49+2 which is 51

If a = -2, b= -5, and c = -6, then a - b + c=?

Answers

Answer:

a - b + c = - 3

Explain

a = - 2

b = - 5

c = - 6

Now,

a - b + c = - 2 - (-5) + (-6)

= - 2 + 5 - 6

= - 8 + 5

= - 3

The perimeter of a movie screen is 76 meters. It is 24 meters wide. How tall is it? meters

Answers

Answer:

Step-by-step explanation:

the perimeter of a rectangle is : 2W + 2L = Perimeter

2*24 + 2L = 76

48 + 2L = 76

2L = 76 -48

2L = 28

L=14

Answer:

14 meters

Step-by-step explanation:

Assuming the movie screen is a rectangle, there are four sides. Two of those sides are 24 meters. Therefore you would add 24 and 24 to get 48 meters. Then you take 76 and subtract 48. The difference of 76 and 48 is 28. To know how tall the movie screen is you need to divide 28 by two (there are two sides). That's where you get 14 from. Hoped this helped.

Steve is going to buy a bicycle that costs $258.70.
Steve's mother is going to pay for 30% of the bicycle.
His father is going to give him $50.00.
How much will Steve have to pay?

Answers

30% = 0.30

$258.70 * 0.30 = $77.61

$77.61 + $50 = $127.61

$258.70 - $127.61 = $131.09 or 50.67%

Steve will have to pay $131.09 or 50.67% of the bicycle.

The bean, who had prudently stayed behind on the shore, could not but laugh at the event, was unable to stop, and laughed so heartily that she burst.
