Answer 1

Step-by-step explanation:

we know ,

area of circle =πr^2

hence we get from the figure that the diameter of circle is 19 cm and we can find radius

r=d/2

r=18/2=9cm

area of semicircle =πr^2/2

area of Semi circle equals to =22*(9)^2/7/2

=127.2857143

Answer 2

Answer:

Today: Sunday, 11 October 2020

Hour: 23.05 WIB (Indonesian)

_________________________

D = 18

r = 18 ÷ 2 = 9

area of semicircle = πr²/2

area of semicircle = 3.142 . 9²/2

area of semicircle = 3.142 . 81/2

area of semicircle = 254.502/2

area of semicircle = 127.251 cm²

Step-by-step explanation:

1. Add exponents: b³⁺² = b⁵

2. Negative and Negative = positive

2*8 = 16

m⁴⁺⁵ = m⁹

Hence: + 16m⁹

Answer:

Find the percent of change: original:80 new:64

Answers

First we need to know the difference between them:
80 − 64 = 16

Now we need this difference as a percentage:
16
64
×
100
=
25 %

Explanation:
We divide by 64 because we want to know how much the number has changed from its original value.
We multiply by 100 because 'per cent' means 'how many out of 100'.

Explanation:
The formula for calculating the percent change in a value between two points in time is:
p=N−O/ O⋅ 100
Where:
p is the percent change - what we are solving for in this problem.
N is the New Value - 80 in this problem.
O is the Old Value - 64 in this problem.
Substituting and solving for
p gives:
p = 80 − 64/ 64 ⋅ 100
p = 16 /64 ⋅100
p = 1600 / 64
p = 25
The percentage change between 64 and 80 is a 25% increase.
So it’s 2

x - y = 1 in slope intercept form

Answers

Answer:

y = x - 1

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c

Given

x - y = 1 ( add y to both sides )

x = y + 1 ( subtract 1 from both sides )

x - 1 = y , that is

y = x - 1 ← in slope- intercept form
