Answer:
shaded/square = (50π cm²)/(400 cm²) = π/8
Step-by-step explanation:
The quarter circle has area ...
A = (1/4)(πr²) = π/4(20 cm)² = 100π cm²
The half-circle has area ...
A = (1/2)(πr²) = π/2(10 cm)² = 50π cm²
Then the area of the shaded portion is ...
shaded = 100π cm² -50π cm² = 50π cm²
__
The area of the square is ...
A = s² = (20 cm)² = 400 cm²
Then the ratio of interest is ...
shaded/square = (50π cm²)/(400 cm²) = π/8
What is the area pls

HELP ASAP how do you find the missing angle measurement In s set complementary angles
Answer:
x + y =90
Step-by-step explanation:
So to find any angle in a complementary set you would subtract the angle given by 90.
Easy way to remember what complementary means is the C is like the curve of 9 in 90 and in supplementary the S is like half a 8 in 180.

the sum of five consecutive numbers is 700, what is the first number?
Answer:
The first number is 138.
Step-by-step explanation:
Let the first number be x.
Then since they are consecutive numbers, the second number will be (x + 1), the third (x + 2), the fourth (x + 3) and the fifth being (x + 4).
We are given that their sum is 700. Therefore:
[tex]x+(x+1)+(x+2)+(x+3)+(x+4)=700[/tex]
Solve for x. Combine like terms:
[tex]5x+10=700[/tex]
Subtract 10 from both sides:
[tex]5x=690[/tex]
Divide both sides by five. Therefore:
[tex]x=138[/tex]
The first number is 138.
Answer:
138
Step-by-step explanation:
(n) + (n+1) + (n+2) + (n+3) + (n+4) = 700
5n + 10 = 700
5n = 690
n = 138

A wildlife refuge has 200 birds when it is first established. It is so
successful that the number of birds increases by 25% every year.
Write a function to model the situation.
Find the number of birds present after 7 years.
Answer:
550 birds
Step-by-step explanation:
25% × 7 = 175%
100% + 175% = 275%
[tex]\frac{y}{200} :\frac{275}{100}[/tex]
y × 100 = 275 × 200
100y = 55000
100y ÷ 100 = 55000 ÷ 100
y = 550
Answer:
200*1.25ˣ
954
Step-by-step explanation:
let x= years
200*1.25ˣ = birds
plug in 7 for x
200*1.25⁷=953.6743164

Answer:
∠ 1 = 94°
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
130° is an exterior angle of the triangle, then
∠ 1 + 36° = 130° ( subtract 36° from both sides )
∠ 1 = 94°
Given that f(x) = 4x + 5 and g(x) = x2 - 2x - 2, find (f + g)(x).
A) (f + g)(x) = x2 + 2x+3
B) (f + g)(x) = x2 + 6x+ 3
C) (f + g)(x) = -x2 + 6x + 7
D) (f + g)(x) = – x2 + 2x - 7
Answer:
A
Step-by-step explanation:
We are given the two functions:
[tex]f(x)=4x+5\text{ and } g(x)=x^2-2x-2[/tex]
And we want to find:
[tex](f+g)(x)[/tex]
This is equivalent to:
[tex]=f(x)+g(x)[/tex]
Substitute:
[tex]=(4x+5)+(x^2-2x-2)[/tex]
Rearrange:
[tex]=(x^2)+(4x-2x)+(5-2)[/tex]
Combine like terms. Hence:
[tex](f+g)(x)=x^2+2x+3[/tex]
Our answer is A.
Which Relationships have the same constant of proportionality between Y and X the following table?
Answer: do you have a picture
Step-by-step explanation:
two numbers which differ by 46
Answer:
The number 1 and 47
or 13 and 59
Answer:
16 and 62
Step-by-step explanation:
Two variables x and y. x < y.
y - x = 46
y = 46 + x
4x = y + 2
y = 46 + x in 4x = y + 2
4x + y = x + y + 46 + 2
4x + y - y = x + y - y + 46 + 2
4x = x + 48
4x - x = x - x + 48
3x = 48
3x ÷ 3 = 48 ÷ 3
x = 16
y = x + 46
y = 16 + 46
y = 62

Carl can paint a room 3 hours faster than Jennifer can. If they work together, they can complete the job in 2 hours. Using complete sentences, explain each step in figuring out how to determine the time it would take Jennifer to complete this job on her ow
Answer:
If they would both work at the same speed they would each take 4 hours to complete the room. So in total they would work 8 hours. But because Carl can finish three hours before Jennifer 3 hours of the eight already got to Jennifer. Then we divide the resting 5 hours by the two and then we have:
Jennifer:
3+2,5=5,5
Carl:
2,5

Need helpppp assignments due tomorrow :(
Answer:
8^(-3) = 0.00195 or 1/512
Step-by-step explanation:
Given: "the log to the base 8 of 1/512" is 3 is actually false. The correct version is "the log to the base 8 of 1/512" is -3 (negative 3). (Log form.)
Please note: 8^(-3) = 0.00195 or 1/512 (This is in exponential form.)

Step-by-step explanation:
Things you should before solving this question :-
a²- b² = (a + b)(a - b)where a and b are any two variables.
SIMPLIFYING THE EXPRESSION
[tex] \frac{ {x}^{2} - 9 }{3 {x}^{2} + 8x - 3} \div \frac{x - 3}{x + 2} \\ [/tex]
using the identity discussed above
[tex] \frac{ (x + 3)(x - 3) }{3 {x}^{2} + 8x - 3} \div \frac{x - 3}{x + 2} [/tex]
simplifying 3x² + 8x - 3
[tex] \frac{ {x}^{2} - 9 }{3 {x}^{2} + 9x -x - 3} \div \frac{x - 3}{x + 2} [/tex]
as 8x can be written as 9x - x
[tex] \frac{ (x - 3)(x + 3) }{3 {x}(x + 3) - 1(x + 3)} \div \frac{x - 3}{x + 2} \\ \frac{ (x - 3)(x + 3) }{(3 {x} - 1)(x + 3) } \div \frac{x - 3}{x + 2} [/tex]
flipping the fraction that follows division sign and inserting multiply in place of divide
[tex] \frac{ (x - 3)(x + 3) }{(3 {x} - 1)(x + 3) } \times \frac{x + 2}{x - 3} [/tex]
canceling (x - 3) and (x + 3) as they're common in both denominator and numerator
