Answer:

152% is the shaded area.

Step-by-step explanation:

=> 25/25 + 13/25
=> 38/25

Hence, 38 squares are shaded in both figures. To find a percentage of the shaded region, we must multiply the fraction by 100.

=> 38/25 x 100
=> 38/1 x 4
=> 152

Hence, 152% is the shaded area.

Hoped this helped.

Answer:

52%

Step-by-step explanation:

In the box that is fully filled with squares, it can be shown as a 100%

There is a total of 25 squares and only 13 is shaded, so you can use a formula to find the percentage

$\frac{13}{25}$ ×100= 52%

Hope it is right, ask any questions if unsure :)

The answer was actually 152% as they is a fully filled square on the left side so you had to add the 100 and 52 which gives 152%

Solve the inequality and express your answer in interval notation x^2+8x-7<0

balandron [24]

Answer:

(-8.8, 0.8)

Step-by-step explanation:

x^2+8x-7<0
x^2 + 8x + 16 - 23 < 0
(x + 4)^2 < 23
|x + 4| < √23 ≈ 4.8

1 .

x + 4 < 4.8

x < 0.8

-(x + 4) < 4.8

x + 4 > - 4.8

x > - 8.8

Combination of the two intervals:

x = (-8.8, 0.8)

Is 600 mm greater than 5 m

sladkih [1.3K]

No, 600 mm is less that 5 m

1 meter = 1000 millimeters

That means that to find out how many millimeters are in 5 m, one way you could calculate it is by multiplying 5 by 1000

5 • 1000 = 5000, so 5 m = 5000. Since 600 < 5000, 600 mm < 5 m

Simplify completely quantity x squared plus 4 x minus 45 all over x squared plus 10 x plus 9 and find the restrictions on the va

dem82 [27]

(x² + 4x - 45)/(x² + 10x + 9)

Numerator = N = x² + 4x - 45 
= x² + 9x - 5x - 45
= (x² + 9x) - (5x + 45)
= x(x + 9) - 5(x + 9)
= (x + 9)(x - 5)

Denominator = D = x² + 10x + 9 
= x² + x + 9x + 9
= (x² + x) + (9x + 9)
= x(x + 1) + 9(x + 1)
= (x + 1)(x + 9)

Hence, the given expr. = N/D 
= {(x + 9)(x - 5)}/{(x + 1)(x + 9)
= (x - 5)/(x + 1)

Restrictions : x ≠ - 1, x = 5 

I hope my answer has come to your help. Thank you for posting your question here in Brainly.

A survey is taken among customers of a fast-food restaurant to determine preference for hamburger or chicken. Of 200 respondents

kicyunya [14]

Answer:

Hamburger Chicken

Adults 65 60 125

children 55 20 75

120 80 200

a)What is the probability that a randomly selected individual is an adult?

Total no. of adults = 125

Total no. of people 200

The probability that a randomly selected individual is an adult = $\frac{125}{200}=0.625$

b) What is the probability that a randomly selected individual is a child and prefers chicken?

No. of child prefers chicken = 20

The probability that a randomly selected individual is a child and prefers chicken= $\frac{20}{200}=0.1$

c)Given the person is a child, what is the probability that this child prefers a hamburger?

No. of children prefer hamburger = 55

No. of child = 75

The probability that this child prefers a hamburger= $\frac{35}{75}=0.46$

d) Assume we know that a person has ordered chicken, what is the probability that this individual is an adult?

No. of adults prefer chicken = 60

No. of total people like chicken = 80

A person has ordered chicken, the probability that this individual is an adult= $\frac{60}{80}=0.75$
