Is 6/12 and 15/30 proportional?

Answers

Answer:

yes

Step-by-step explanation:

6 is half of 12. 15 is half of 30. The ratios are equal, so the fractions are proportional.

Answer: yes

Also, you can reduce both fractions.

Divide the numerator and denominator of 6/12 by 6 to get 1/2.

Divide the numerator and denominator of 15/30 by 15 to get 1/2.

Since both fractions reduce to 1/2, 6/12 and 15/30 are equivalent fractions and are proportional.

Answers

Answer:
x=9
Step-by-step explanation:
Diagonals of a parallelogram bisect each other. For quadrilateral LMNO to be a parallelogram, LP must equal PN, and OP must equal PM.
Set OP equal to PM and solve for x.
PM=OP
3x-9=18
Add 9 to both sides.
3x=27
Divide both sides by 3.
x=9

The population of bacteria in an
experiment is increasing by 90% each
day. If there were 100 bacteria at the
beginning of the experiment, predict the
number of bacteria in 5 days.
First, complete the equation:
Future Amount = 100(1 +0.90) [?]

Answers

Answer:

5

Step-by-step explanation:

5 makes sense since the period of time this takes place is 5 days. therefore [?] should be 5

The number of bacterias increases in 5 days will be 1790.

What will be the bacterial growth?

The bacteria number is increasing day by day the function which shows the bacterial growth is given as Future amount = 100(1+0.9)⁴'⁵.

Now the bacterial growth will be:-

Future amount    =   100   (   1   +  0.9   )⁴'⁵.

Future amount    =   100   (   1.9   ) ⁴'⁵.

Future amount   =   1790

Therefore the number of bacterias increases in 5 days will be 1790.

Using zero product property, find the values of x. (Hint: You must set factored parts equal to 0). (x+10)(2x-4)=0

I know there are two answers but I need an explanation please!! I want to understand this

Answers

Answer:

x = - 10, x = 2

Step-by-step explanation:

Given

(x + 10)(2x - 4) = 0

Equate each factor to zero and solve for x ( zero product property )

x + 10 = 0 ⇒ x = - 10

2x - 4 = 0 ⇒ 2x = 4 ⇒ x = 2

Answers

Answer:

It could be any of them.

Step-by-step explanation:

First off, It could be said that (2c-d)(2c-d) doesn't belong because it includes two subtractions signs and none of the others do.

Secondly, It could be said that (2c+d)(2c-d) doesn't belong because it includes one subtraction sign and one addition sign and none of the others do.

Thirdly, It could be said that (2c+d)(2c+d) doesn't belong because it includes two addition signs, and none of the others do.

Finally, it could be said that (c+d)(c+d) doesn't belong because it doesn't have a multiplying factor of 2 within the parentheses.

A car bought for $13,000 depreciates at a rate of 15% per year. Use an exponential function to find the value of the car after 5 years.

Answers

Answer:

$ 11093

Explanation:

Recall that the formula for compound interest is:

A = P ( 1 + r/ n ) n ( t )  

−−−−−−−−−−−−−−−−−−−−−−  

where:

A =  future value

P  =  principal (starting) amount

r  =  annual interest rate, expressed as a decimal

n  =  number of times the interest is compounded in a year

t  =  number of years compound interest occurs for

1 . Start by substituting your known values into the formula. Note that the annual interest rate is  − 0.15  since the car depreciates (becomes lower in value) each year.

A = 25000 ( 1 + − 0.15 1 ) 1 ( 5 )  

2 . Solve for  A .

A = 25000 ( 0.85 ) )5

A = 11092.63

Ann is going on vacation. Ann dog food for a pet sitter to feed her dog Maggie while she's away she leaves 24 cans of wet food and a 38 ounce bag of dry food Maggie East three 1/ fourth can of wet food in five 3/4 ounces of dry for the state of mega eatery normal portion of wet food and dry food each day how many days can add be gone before Maggie runs out of either wet food or dry food? Plz don’t try to scam me by sending a link!!

Answers

1/4x = 24 for cans
Multiply both sides by 4 (the multiplicative inverse of 1/4)
x = 96 days

3/4x = 38 for dry food
Multiply both sides by 4
3x = 152
x = 50.666667

So I would say Ann can be gone 50 days before Maggie runs out of food. I don’t think they would count the 2/3 of a day. She will run out of dry food before canned food.
