Answer:

question 4.

D (x-10)

Step-by-step explanation:

question 4.

x^2 - 8x - 20

(x -10)(x+2)

x² + 8x - 20 [-20 = -2 × 10]

x² - 2x + 10x - 20 [8 = -2 + 10]

x(x - 2) + 10(x - 2)

(x + 10) (x - 2)

Answer:

wouldn't they both be 88

I'm not sure if that's correct though

Answer:

x = 88

y = 88

Step-by-step explanation:

66 + 26 + x = 180 (collect like terms)

92 + x = 180 (subtract 92 on both sides)

x = 88

y = x

y = 88

They are vertical so their measures are the same.

Hope this helps ya!!

Answer:

No its not a right angle.

Answer:

67%

Step-by-step explanation:

This is because 67% is basically 67/100 as a fraction and 3/5 is only 60%, all you need to know is the facts about fraction to percentage

Answer:

slope(m)=4 and

y-intercept(c)=-5/2

Step-by-step explanation:

here,8x-2y=5

reducing it into slop intercept form we get,

2y=8x-5

or,y=8/2x+(-5/2)

or,y=4x+(-5/2)

comparing it with y=mx+c we get,

slope(m)=4 and

y-intercept (c)=-5/2

Answer:

10m - 3.3n - 1.8

Welp here is the answer to your question, 372/35 in exact form. in mixed number form it is 10 22/35

Answer:

D i believe.

Step-by-step explanation:

Hope this helps :)

The equation with the greatest growth factor is d(t) = 400 . 3^t

Correct option is D.

As per the given data:

Equations representing the number of bacteria in four different dishes as a function of time, t in days, are given.

To find out the equation with the greatest growth factor:

Growth Factor = Term whose power is raised to t.

For option (A), Growth Factor = (5/6) = 0.834

For option (B), Growth Factor = (1/50) = 0.02

For option (C), Growth Factor = (5/2) = 2.5

For option (D), Growth Factor = (3) = 3

Hence, the equation with the greatest growth factor is d(t) = 400 . 3^t

Answer:

39.27

Step-by-step explanation:

The area of a semi-circle is pi times the radius squared divided by 2. So basically standard area of a circle formula (pi times the radius squared) but then you add in the extra step of dividing it by 2.

The formula looks like this:

π × r² ÷ 2

The radius is half the diameter of the circle. So basically think of it as a line to the middle of the circle. Our diameter is 10, (the diameter is the entire length of the circle. It gives us this already. If you need diameter and only have the radius add the radius together twice or multiply it by 2 to get the diameter. Fun fact..?)

and it tells us to substitute pi for 3.142.

So, plugging our numbers in we get:

3.142 x 5^2 ÷ 2 = 39.275.

Cut out the 3rd decimal place (5) as it tells us to only include the first 2 decimal places, and we finally end up with 39.27.

Hope this helps and have a nice day!

Answer:

a) 1/10

b) 1/2

c) 1/2

d) 2/5

Step-by-step explanation:

Probability is the likelihood or chance that an event will occur.

Probability = Total event/Total sample space

Since there are ten ball in the bag numbered 1 to 10

S = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}

n(S) = 10

Total sample space = 10

a) If we are to get the probability of picking the number 7.

(E) = {7}

n(E) = 1

Event = 1

Pr(picking 7) = 1/10

b) a) If we are to get the probability of picking an odd number

(E) = {1, 3, 5, 7 , 9}

n(E) = 5

Event = 5

Pr(an odd number) = 5/10 = 1/2

c) a) If we are to get the probability of picking an even number

(E) = {2, 4, 6, 8,10}

n(E) = 5

Event = 5

Pr(an even number) = 5/10 = 1/2

d) a) If we are to get the probability of picking prime

(E) = {2, 3, 5, 7}

n(E) = 4

Event = 4

Pr(prime) = 4/10 = 2/5

Step-by-step explanation:

Answer:

(-1,4)

Step-by-step explanation:

Answer:

B. Robert's sister's sales total $18.00.

E. Robert's sister's sales are represented by x when solving 3.5x = 63 .

Step-by-step explanation:

Let

Robert sister's sales = x

Robert sales = 2.5 * x

= 2.5x

Total sales = Robert sister's sales + Robert sales

63 = x + 2.5x

63 = 3.5x

Divide both sides by 3.5

x = 63 ÷ 3.5

= 18

x = $18.00

Robert sales = 2.5x

= 2.5(18)

= $45.00

A. Robert's sales are represented by x when solving 3.5x=63 .

No

B. Robert's sister's sales total $18.00.

Yes

C. Robert's sales are represented by x when solving 2.6x=63 .

No

D. Robert's sales total $25.20.

No

E. Robert's sister's sales are represented by x when solving 3.5x = 63 .

Yes
