20/15

Divide 20 by 5 to get 4.

Divide 15 by 5 to get 3.

Answer:

20) C

22) B

Step-by-step explanation:

20) 4/3=x+10/15

cross multiply

4×15=3(x+10)

60=3x+30

3x=60-30

3x=30

divide both sides by 3

x=10

Answer:

Step-by-step explanation:

tamika eats jelly beans at a rate of 3 jellybeans ber miniute since it would be 12/4. and it takes tamika 30 minutes which means that the snack pack had 90 jellybeans.

James eats jellybeans at a rate of 4 jellybeans per miniute so it took james 22.5 miniutes to eat a snack pack.

so you would subtract tamikas minutes(30 min) - james minutes(22.5) and get 7.5 minutes.

James took 7 minutes and 30 seconds less than Tamika to eat his jelly beans.

James took 7.5 fewer minutes to eat a snack-size pack of jelly beans as compared to Tamika

A unit rate means a rate for one of something.

It is written as a ratio with a denominator of one.

We have,

Tamika:

Rate of eating jellybeans = 12 jelly beans per 4 minutes.

12 beans = 4 minutes

Divide it by 4 into both sides

We get,

3 beans = 1 minute ___(1)

Tamika took 30 minutes to finish snack-size beans.

This means from (1),

3 x 30 jelly beans= 30 minutes

90 jelly beans = 30 minutes

There are 90 jellybeans in snack-size beans.

James:

Rate of eating the jellybeans = 28 jellybeans per 7 minutes

It can be written as:

28 jelly beans = 7 minutes

Multiplying 90/28 on both sides we get,

90 jelly beans = (90/28) x 7 minutes

90 jelly beans = 90/4 minutes = 22.5 minutes

This means James takes 22.5 minutes to finish snack-size jelly beans.

We see that,

The time took for Tamika to finish snack-size jelly beans = 30 minutes

The time took for James to finish snack-size jelly beans = 22.5 minutes

we have,

30 - 22.5 = 7.5

Thus,

James took 7.5 fewer minutes to eat a snack-size pack of jelly beans as compared to Tamika

\(\frac{16}{27}\)

Step-by-step explanation:

From the table, we notice that the total number of students is:

\(3+10+8+6=27\)

Then, along the second column of the table, we notice that the number of students who do not have a brother is:

\(10+6=16\)

So, the probability that a randomly chosen student does not have a brother is:

\(\frac{\text{number of students who do not have a brother}}{\text{total number of students}}=\frac{16}{27}\)

Answer:

\(351.8mi^2\)

Step-by-step explanation:

Hey there!

Well the formula to find the surface area of a cylinder is,

\(2\pi rh+2\pi r^2\),

So with the h and r being 10 and 4 lets plug it in.

\(2\pi (4)(10)+2\pi (4)^2\)

Let's solve!

2π40 + 2π16

80π + 32π

251.3 + 100.5

= \(351.8mi^2\)

Hope this helps :)

Answer:

351.9 mi^2

Step-by-step explanation:

The surface area of a cylinder can be found using the following formula.

\(SA=2\pi r^2+2\pi rh\)

We know that the height of the cylinder is 10 miles and the radius is 4 miles.

h= 10 mi

r= 4 mi

\(SA=2\pi (4 mi)^2+2\pi (4 mi)(10 mi)\)

First, evaluate the exponent 4 mi^2.

4 mi^2= 4 mi * 4 mi = 16 mi^2

\(SA=2\pi 16 mi^2+2\pi (4 mi)(10 mi)\)

Next, multiply 16 and 2pi

\(SA=100.530965 mi^2+2\pi(4 mi)(10mi)\)

Next, multiply 4 and 10

\(SA=100.530965 mi^2+2\pi40mi^2\)

Multiply 40 and 2 pi

\(SA=100.530965 mi^2+251.327412mi^2\)

Add the 2 numbers together

\(SA=351.858377 mi^2\)

Round to the nearest tenth. The 5 in the hundredth place tells us to round the 8 to a 9 in the tenth place.

\(SA=351.9 mi^2\)

The surface area of the cylinder is about 351.9 square miles.

Answer:

its the 3rd one

Step-by-step explanation:

Answer:

Bobby added 6x and 5x which was correct because they're like terms

Bobby then combined 11x and 2y which was incorrect, they're not like terms because they have different variables

to correct his mistake he has to stop simplifying the equation at 11x + 2y because that is as far as you can simplify it

Bobby Joe has done combination properly till \(11x + 2y\) because, \(6x + 5x\) are like terms and has common variable \(‘x’\) but, he messed up when he started combining \(11x + 2y\)because, they are not at all like terms and doesn't have common variable. So, to recover it he should stop combining till \(11x + 2y\).

Answer:Volume of a in z = 876 ounces Step-by-step explanation:For z, the ratio of x and y is 3 : 11x : y = 3 : 11 , which means in 14 p

Step-by-step explanation:One ounce of solution x contains only ingredients a and b in the ratio of 2:3 one ounce of solution y count aims only ingredients a and b in the ratio of 1:2 if solution z is created by mixing solutions x

Answer:

Step-by-step explanation:

pplying proportion, 2520 ounces of solution Z will contain 44040 ounces of ingredient a.

How to Use Proportion to Calculate The Ounces Needed of a Solution?

To determine the number of ounces of ingredient a in 2520 ounces of solution Z, we need to first calculate the proportion of ingredient a in solutions X and Y, and then use that information to determine the proportion of ingredient a in solution Z.

Solution X contains 2 ounces of ingredient a and 3 ounces of ingredient b in one ounce of solution, so the proportion of ingredient a is 2/(2+3) = 2/5.

Solution Y contains 1 ounce of ingredient a and 2 ounces of ingredient b in one ounce of solution, so the proportion of ingredient a is 1/(1+2) = 1/3.

Solution Z is created by mixing solutions X and Y in a ratio of 3:11, so 3 ounces of solution X are mixed with 11 ounces of solution Y.

Thus, the proportion of ingredient a in solution Z = (32/5) + (111/3) = 6/5 + 11/3.

To find out the number of ounces of ingredient a in 2520 ounces of solution Z, we need to multiply the proportion of ingredient a with the number of ounces of solution Z

2520 * (6/5 + 11/3) = 2520 * (6/5 + 11/3) = 2520 * (252/15 + 11/3) = 2520 * (16+11/3) = 2520 * (16+11/3) = 2520 * (16+11/3) = 2520 * (16+37/3) = 2520 * (16+37/3) = 2520 * (53/3) = 252053/3 = 252017.66666 = 44040 ounces of ingredient a.

=====================================================

Explanation:

Rearrange the first equation into \(-x^2+y^2 = 16\)

So we have this equivalent system

\(\begin{cases}-x^2+y^2 = 16\\\\x^2-y^2=16\end{cases}\)

If you add the terms straight down, then you'll find that the x^2 and y^2 terms add to 0. The right hand side terms add to 16+16 = 32

We are left with the equation 0 = 32, which is a false equation or contradiction. Therefore, there are no solutions. We say the system is inconsistent. The two graphs do not intersect at all as shown in the diagram below. We have two hyperbolas in which the branches extend off to infinity to slowly approach the asymptotes. They never actually get to the asymptotes, but only get closer.

Answer:

No. The data shows that it rains more than once in 5 of the 12 months shown. She says she wants it to rain less than an inch every month. And with such a small sample, a mean of 0.9 and a median of 0.7 could change drastically.

Answer:

All multiples of 10 end with 0 only. So 35 must be wrong as it ends with 5. Therefore, Greg is incorrect.
