Hailstones form when strong winds support ice particles high in clouds. We can assume that the diameter of a hailstone varies directly with the time the hailstone takes to form. A hailstone with a diameter of 0.75 inches takes about 12 minutes to form. Write an equation that gives the hailstone’s diameter d after t minutes. Then find the diameter of a hailstone that takes 20 minutes to form.

The length of a rectangular cement patio is 3 feet less than three times the width. The sum of the length and width of the patio is 21 feet. Find the length of the patio.

Answers

Answer: The length is 15 feet.

Step-by-step explanation:

L = 3w - 3 (length is 3 feet less than three times the width)21 = w + (3w -3)21 = 4w - 3 (add like terms)24 = 4w (substract 3 from both sides)6 = w <-- width

But, the problem is asking for the length...

L = 3w - 3L = 3(6) - 3L = 18 - 3L = 15 ft

What is the initial value of the function represented by this graph?

Answers

Answer:

We conclude that the initial value of the function is 6.

Hence, option D is correct.

Step-by-step explanation:

The initial value of the function can be determined by setting x = 0 and determining the corresponding y value.

In other words, the initial value is basically the y-intercept of the graph.

It is the output value when the input value x = 0.

Given the graph, it is clear that:

at x = 0, y = 6

Thus, at x = 0, the value of y is 6.

i.e. the y-intercept b = 6.

Therefore, we conclude that the initial value of the function is 6.

Hence, option D is correct.

Answer:

6

Step-by-step explanation:

The initial value is the y-intercept or where the line crosses the y axis.

You have a bag with 12 jelly beans in it 4 red 2 black 5 yellow and 1 pink what is the probability of not picking a black one

Answers

10:12. or 83.3%. so you have a 10 in 12 chance to not get a black one.

Answer:

[tex]\boxed {\boxed {\sf \frac{5}{6} \ or \ 0.833}}[/tex]

Step-by-step explanation:

Probability can be found by dividing the favorable outcomes by the total outcomes.

[tex]P=\frac{favorable \ outcomes}{total \ outcomes}[/tex]

In this problem, a favorable outcome is not picking a black jelly bean. The total outcomes is the total number of jelly beans.

[tex]P( \ not \ black \ jelly \ bean)=\frac{not \ black \ jelly \ beans}{all \ jelly \ beans}[/tex]

There are 10 jelly beans that are not black (4 red+5 yellow + 1 pink =10) There are 12 total jelly beans (4 red+ 2 black+ 5 yellow + 1 pink= 12)

[tex]P( not \ black \ jelly \ bean )=\frac{10}{12}[/tex]

This fraction can be reduced. Both the numerator and denominator can be divided by 2.

[tex]P(not \ black \ jelly \ bean)=\frac{10/2}{12/2}[/tex]

[tex]P(not \ black \ jelly \ bean)=\frac{5}{6}[/tex]

Probabilty can also be written as a decimal.

[tex]P(not \ black \ jelly \ bean)=0.833[/tex]

The probabilty of not picking a black jelly bean is 5/6 or 0.833

Carlos drove to the train station and back. The trip there took five hours and the trip back took four hours. What was Carlos' average speed on the trip there if he averaged 68 mph on the return trip?

Answers

Answer: 54.4 mph

Step-by-step explanation:

First find the distance to the train station. If it took Carlos 4 hours to come back driving at 68 mph, the distance is:

= Speed * time

= 68 * 4

= 272 miles

This means that Carlos drove for 5 hours to cover 272 miles the first time. His average speed was therefore:

= Distance / time

= 272/5

= 54.4 mph

4/-2 flipped over the x axis

Answers

Answer:

I suppose that here we have:

"(4, - 2) flipped over the x-axis"

Regardless of that, i will answer this in a kind of general way.

When we have a point (x, y) and we do a reflection over the x-axis (or the line y = 0, is the same) the reflected point will be (x, - y)

If we instead had a reflection over the y-axis (or the line x = 0) the reflected point will be (-x, y)

Then if we have the point (4, -2) and we have a reflection over the x-axis, the sign of the y-component needs to change.

Then the reflected point will be (4, -(-2)) = (4, 2)

A committee must be formed with 5 teachers and 4 students. If there are 6 teachers to choose from, and 15 students, how many different ways could the committee be mad?

Answers

Answer:

8190 ways

Step-by-step explanation:

Given

[tex]Teachers = 6[/tex]

[tex]Students = 15[/tex]

Selection

[tex]Students = 4[/tex]

[tex]Teachers = 5[/tex]

Required

Number of ways of selection

4 students can be selected from 15 students in:

[tex]Students= ^{15}C_4[/tex]

Similarly.

5 teachers can be selected from 6 teachers in:

[tex]Teachers= ^{6}C_5[/tex]

So, the required number of selection is:

[tex]Selection = ^{15}C_4 * ^6C_5[/tex]

Apply combination formula:

[tex]Selection = \frac{15!}{(15-4)!4!} * \frac{6!}{(6-5)!5!}[/tex]

[tex]Selection = \frac{15!}{11!4!} * \frac{6!}{1!5!}[/tex]

[tex]Selection = \frac{15*14*13*12*11!}{11!*4*3*2*1} * \frac{6*5!}{1*5!}[/tex]

[tex]Selection = \frac{15*14*13*12}{4*3*2*1} * \frac{6}{1}[/tex]

[tex]Selection = \frac{32760}{24} * 6[/tex]

[tex]Selection = 1365 * 6[/tex]

[tex]Selection = 8190[/tex]

Mrs. Femandez starts out with $255 in her checking account. She deposits $35 on Monday. Tuesday afternoon she
writes a check for $75
Which expression could be used to find Mrs. Femandez's new account balance?

Answers

Answer:

255+35-75

Step-by-step explanation:

Since we are trying to find the account balance, we consider anything in or going to the account to be positive.

255 is positive since it is in the account

35 is positive since it is going into the account

75 is negative because it is going out of the account

so the final expression to express the amount is the checking account would be 255+35-75

Answer:

a. $73.75b. 57 rides

Step-by-step explanation:

a.

Initial value of the pass is $100

From the difference in values we can see the cost of one ride is $1.75

The formula:

P(r) = 100 - 1.75r, P- the value of the pass, r- the number of rides

Value of the pass after 15 rides:

P(15) = 100 - 1.75*15 = 73.75

b.

Number of possible rides:

0 = 100 - 1.75r1.75r = 100r = 100/1.75r = 57 (rounded to the whole number)

Step-by-step explanation:

3. Substitution, Elimination, and Graphing are ALL three methods to solve a system of equations, whether they are in three variables or two. The only differense is that with graphing, you will easily spot when a system is dependent [Infinitive Solutions], inconsistent [no solution], and\or consistent [one solution]. With elimination, you want to eliminate one set of variables [set to zero] so that it will be alot simpler solving the system, then latre on, substitute whatever value solved for the remaining set of variables back into the system to solve for the eliminated variable. Finally, with substitution, all you have to do is choose which variable you want to solve for in all three equations, or two. It really does not matter which one, as long as you follow the proper universal concept in using the Order of Operations.

2. This is self-explanatory really. The only time you cannot use any method is when the linear equations form parallel lines. Otherwise, you will always have one or infinite solutions.
