Answers

Answer 1
You have to use PEMDAS to answer. So I believe that it is -3. Explanation the 8Z +Z is 9Z. Then it cancels out because of the -9z. So now you must and be -5+2 which is three

These angles are on the exterior. To find the alternative angle look on the opposite side of the transversal.

A skateboard costs $240. The sales tax on the skateboard is $12. What the percent of the sales tax?

Answers

Answer:

5%

Step-by-step explanation:

12 divided by 240 is 0.05, which is a PERCENTAGE FRACTION (as I like to call it).

This means that you can easily make this into a percentage.

Example Percentage Fractions:

A whole number, like 1 for example, is 100% or more.

The number 1 is 100%, and 2 is 200% and 4.25 is 425%

But since 12 divided by 240, in this problem, is 0.05, it is 5%.

Example are:

0.08 is 8%

0.02 is 2%

0.43 is 43%

0.79 is 79%

It's pretty simple.

Serenity practices the piano 1036 minutes in 4 weeks. If t represents the total time she practices for any number of days, d, write a proportional equation for t in terms of d that matches the context

Answers

Answer:

The proportional equation is [tex]t = 37d[/tex]

Step-by-step explanation:

Serenity practices the piano 1036 minutes in 4 weeks.

Each week has 7 days, so 4 weeks = 4*7 = 28 days.

The amount of minutes she practices per day is given by:

[tex]\frac{1036}{28} = 37[/tex]

So, after d days, the total amount of time she will have practiced is given by:

[tex]t = 37d[/tex]

Nine bands are to perform at a weekend festival. Suppose you want to determine how many different ways there are to schedule their appearances. Would you use a combination or a permutation?

Answers

Answer:

permutation

Step-by-step explanation:

Analyzing the information in the question above, it is correct to say that it is necessary to use permutation, since the ORDER matters, since there is a need to program the band's appearances.

Permutation can be understood as an arrangement in which n = p, where n is the number of elements in the set and p is the number of available elements.

Therefore, the permutation of nine bands is:

Pn = n!

P9 = 9!

p9 = 362880

Levi buys eggs and lemons at the store.

• He pays a total of $29.33.

• He pays a total of $5.39 for the eggs.

• He buys 6 bags of lemons that each cost the same amount.

How much does each bag of lemons cost?

Answers

Answer:

Each bag of lemons cost $3.99.

Step-by-step explanation:

29.33 - 5.39 = 23.94

23.94 / 6 = 3.99

29.33-5.39
= 23.94
23.94/6
=3.99
Therefore each lemon is $3.99

One winter day, the temperature in Houston is 8 Celsius. Find the temperatures in these other cities. Explain or show your reasoning.
In Orlando, it is 17 warmer than it is in Houston
In Salt Lake City, it is 18 colder than it is in Houston
In Minneapolis, it is 25 colder than it is in Houston
In Fairbanks, it is 12 colder than it is in Minneapolis
Write an addition equation that represents the relationship between the temperature in Houston and the temperature in Fairbanks.

Answers

Orlando = 25° because 17+8
Salt Lake city = -10° because 8-18
Minneapolis = -17° because 8-25
Fairbanks = -29° because -17-12

Houston = 8° - 37° = Fairbanks

Hence, the temperatures in these other cities are

Orlando is [tex]25[/tex] degree

Salt Lake is [tex]-10[/tex] degree

Minneapolis is [tex]-17[/tex] degree

Fairbanks is [tex]-29[/tex] degree

What is the degree?

A degree, usually denoted by °, is a measurement of a plane angle in which one full rotation is [tex]360[/tex] degrees.

Here given that,

One winter day, the temperature in Houston is [tex]8[/tex] Celsius.

In Orlando, it is [tex]17[/tex] warmer than it is in Houston.

In Salt Lake City, it is [tex]18[/tex] colder than it is in Houston.

In Minneapolis, it is [tex]25[/tex] colder than it is in Houston.

In Fairbanks, it is [tex]12[/tex] colder than it is in Minneapolis.

So, it would be

Orlando = [tex]25[/tex] degree

because [tex]17+8=25[/tex] degree

Salt Lake city [tex]= -10[/tex] degree

because [tex]8-18=-10[/tex] degree

Minneapolis [tex]= -17[/tex] degree

because [tex]8-25=-17[/tex] degree

Fairbanks [tex]= -29[/tex] degree

because [tex]-17-12=-29[/tex] degree

Hence, the temperatures in these other cities are

are any two of the three triangles similar? if so write the appropriate similarity statement.​

Answers

Answer:

Angle ABC is similar to PQR.

Postulate is Side side, side similarity

Step-by-step explanation:

In triangle ABC, AC:AB = 4/5 = 0.8

In triangle PQR, PR:PQ = 8/10 = 0.8

Looking at the triangle PQR carefully, we can deduce that QR = PR.

Thus; QR:PQ = 8/10 = 0.8.

Also,BC/AB = 4/5 = 0.8

Also, PR/RQ = 8/8 = 1 and AC/CB = 4/4 = 1

Both triangles have the same proportion of their sides and thus we can say they are similar.

Postulate used is Side, Side, Side similarity.
