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

For Ms Ortiz: 50 = 50x+30y

For Mr Donahue 45=30x+30y

C =Substitution

Answer:

Step-by-step explanation:

45 divided by 30=$1.50

x amount of rulers multiplyed by 1.50

45-55=10$

50 pencils for 10 bucks

50 divided by 10 =5

5     5   5   5 5 5 5 5 5 5

five pencils for five dollers   one doller for one pencil

sorry for the spelling errors  this is all i can do the rest is a bit tricky

Answer:

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

Answer:

B

Step-by-step explanation:

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!!

Step-by-step explanation:

they meet on (-3,-$4) so just plug the numbers in

Answer:

c

Step-by-step explanation:

1/2= 0.5, 1/3= 0.33 ; 0.5+ 0.33= 0.83 or 0.8

Answer:

B and D

Why are both of the answers to the last question correct?

An exponent is a short way to write repeated multiplication. So 212 means the same as 2 • 2 • . . . • 2 • 2.

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

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 and Step-by-step explanation:

We are told that the circumference is 20, and we are asked to find the area.

The equation for circumference is:

C = 2[tex]\pi[/tex]r

We can plug in 20 and solve for r.

20 = 2[tex]\pi[/tex]r

Divide by 2 on both sides.

10 = [tex]\pi[/tex]r

Now divide by [tex]\pi[/tex] on both sides.

[tex]\frac{10}{\pi }[/tex] = r

Now, we can plug this into the area equation:

A = [tex]\pi[/tex][tex]r^{2}[/tex]

A = [tex]\pi[/tex][tex](\frac{10}{\pi } )^{2}[/tex]

A = [tex]\pi[/tex][tex]\frac{100}{\pi ^{2} }[/tex]

A = [tex]\frac{100\pi }{\pi ^{2} }[/tex]

A = [tex]\frac{100}{\pi }[/tex]

Now, we put this into the calculator to solve.

We get:

31.830988618379067153776752674503

We are then told to round to the nearest whole number.

8 is greater than 5, so we round up.

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:

Step-by-step explanation:

The way to find slope is by y2-y1/x2-x1 which gives you slope ,but if you just want the answer its zero.

Answer:

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!
