a O
16 cm
Work out the area of the circle.

Answers

Answer 1

Answer:

perimeter of circle=2πr

16=2πr

r=16/2π=8/πcm

now.

area of circle=πr²=π(8/π)²=π×64/π²=64/(22/7)=64×7/22=20.36cm²

The number of fish in a lake decreased by 25% between last year and this year. This year there are 45 fish in the lake. What was the population of last year

Answers

Answer:

The population of last year was 60.

Step-by-step explanation:

From the information given, as you know that the number of fish in a lake decreased by 25% between last year and this year, the amount of fish this year represents 75% of last year's population as: 100%-25%=75%. With that, you can use a rule of three to find last year's population tha would represent 100% given that 75% is equal to 45 fish.

75%   →  45

100%  →   x

x=(100*45)/75= 60

According to this, the answer is that the population of last year was 60.

Two angels are supplementary. The measure of the large angle is four more than three times the measure of the small angle. Find the measure of both angles.

Answers

Answer:

The measure of the two supplementary angles is

Small angle = x = 44°

Large angle = y = 136

Step-by-step explanation:

Supplementary angles are two angles whose measures add up to 180° .

Let

Small angle = x

Large angle = y

x + y = 180°.... Equation 1

The measure of the large angle is four more than three times the measure of the small angle

Hence: y = 4 + 3x

We substitute 4 + 3x for y in Equation 1

x + 4 + 3x = 180°

4x + 4 = 180°

4x = 180° - 4

4x = 176

x = 176/4

x = 44°

Solve for y

y = 4 + 3x

y = 4 + 3(44)

y = 4 + 132

y = 136°

Therefore, the measure of the two supplementary angles is

Small angle = x = 44°

Large angle = y = 136

Answers

Answer:

85.6%

Step-by-step explanation:

To get two overall performance of Harry, we need to calculate his average score.

Average is also known mean score.

Mean = sum of the score/Total math subjects offered

Mean = 95+ 90+85+40+100+100+85+90/8

Mean = 685/8

Mean = 85.6

Expand and simplify

Answers

Answer:

5-3x

Step-by-step explanation:

To expand this, we start with the distribution of -3 into the parentheses containing x+2

This leaves us with

11-3x-6

From here, simplifying involves combining like terms. The only like terms we have are the constant values 11 and -6

We combine them by subtracting 11-6 to get 5.

This leaves us with our answer,

11-6-3x

5-3x

An alternate way of writing this would be

-3x+5

But this would only be required if we were asked to express the answer in decreasing degree, so don't worry about that for now
