Zara has a collection of 4 marbles: an Aggie, a Bumblebee, a Steelie, and a Tiger. She wants to display them in a row on a shelf, but does not want to put the Steelie and the Tiger next to one another. In how many ways can she do this?
Answers
Answer:
Step-by-step explanation:
Oops I meant "there are 3! = 6 ways to permute ABTS that have TS."
There are 12 different combinations to display marvel that doesn't involve Steelie and the tiger.
What are permutation and combination?A permutation is an orderly arrangement of things or numbers. Combinations are a means to choose items or numbers from a collection or set of items without worrying about the items' chronological order.
Given, Zara has a collection of 4 marbles: an Aggie, a Bumblebee, a Steelie, and a Tiger. She wants to display them in a row on a shelf but does not want to put the Steelie and the Tiger next to one another.
We want the number of ways to permute the string ABST that has S and T separated.
Total ways of displaying marbles = 4! = 24
If S and T are together, then the permutation contains the consecutive pair ST or TS somewhere. We can count these possibilities by regarding ST or TS as a single symbol
permutation of getting them together = 2 * 3!
permutation of getting them together = 12
Thus,
total desired combination = Steelie and tiger do not come together
total desired combination = 24 - 12 = 12
therefore, There are 12 possible combinations of displaying marvel without making Steelie and tiger together.

Step-by-step explanation:

The measure of angle ∠2 in the triangle is 145.
Option D is the correct answer.
We have,
From the figure,
The s and t lines are parallel.
The l and m lines are parallel.
Now,
∠1 and ∠a are corresponding angles.
∠b and ∠a are corresponding angles.
This means,
∠1 = ∠a = ∠b = 35
Now,
∠2 and ∠b add up to a straight angle.
This means,
∠2 + ∠b = 180
∠2 + 35 = 180
∠2 = 180 - 35
∠2 = 145
Thus,
The measure of angle ∠2 is 145.

A band expects to put 15 songs on their next CD. The band writes and records 60% more songs than they expect to put on the CD. During the editing process, 75% of the songs are removed. How many songs will there be on the final CD?
Answers
Answer: 6
Step-by-step explanation:
From the question, we are informed that a band expects to put 15 songs on their next CD and that the band writes and records 60% more songs than they expect to put on the CD. Therefore, the total songs will be:
= 15 + (60% × 15)
= 15 + (0.6 × 15)
= 15 + 9
= 24 songs.
During the editing process, 75% of the songs are removed. The total number of songs that will be there on the final CD will be:
= 24 - (75% × 24)
= 24 - (0.75 × 24)
= 24 - 18
= 6
6 songs will be there on the final CD.

Step-by-step explanation:
I'm going to call the bottom triangle (the one with 3, and 4 as its side lenght), and the top one, b.
So a is 3 times 4/2=12/2=6 sq ft.
b is 6 times 5/2=30/2=15
Answer:
21 ft²
Step-by-step explanation:
A = [tex]A_{1}[/tex] + [tex]A_{2}[/tex]
[tex]A_{1}[/tex] = (5 × 6) ÷ 2 = 15 ft²
[tex]A_{2}[/tex] = (4 × 3) ÷ 2 = 6 ft²
A = 15 + 6 = 21 ft²

Write the standard form of the equation of a line with a slope of 2 passing through the point (-4, -3).
Select one:
a. 2x - y + 5 = 0
b. -x + 2y + 2 = 0
c. x - 2y - 2 = 0
d. -2x + y - 5 = 0
Answers
Step 1: We need to determine b by using slope-intercept form, the given slope, and the given line.
[tex]-3 = 2(-4) + b\\\\-3 = -8 + b\\\\5 = b[/tex]
Step 2: Now we create the slope-intercept form for the line.
[tex]y = 2x + 5[/tex]
Step 3: We can now change the above equation to standard form.
[tex]y = 2x + 5\\\\-2x + y = 5\\\\-2x + y - 5 = 0[/tex]
The equation of the line in STANDARD FORM is: D. -2x + y - 5 = 0.

A store sells rope by the meter. The equation p = .8 L represents the price: p (in dollars) of a piece of nylon rope that is L meters long.
How long is a piece of nylon rope that is $2.80?
Answers
Answer:
3.5 meters
Step-by-step explanation:
Equation: p = 0.8L
Given: p = 2.80
To find the length of a piece of nylon rope that costs $2.80, input the given value of p(2.80) into the equation and solve for L:
p = 0.8L
2.8 = 0.8L
Divide both sides by .8 to isolate L:
[tex]\frac{2.8}{0.8} =\frac{0.8L}{0.8}[/tex]
3.5 = L
The length of a piece of nylon rope that costs $2.80 is 3.5 meters long.
A store has clearance items that have been marked down by 45%. They are having a sale, advertising an additional 35% off clearance items. What percent of the original price do you end up paying?
Answers
Answer:
35.75%
Step-by-step explanation:
Given that:
Markdown % = 45%
Additional percentage off = 35%
45% markdown :
100% - 45% = 55% of item price will be paid.
Furthermore,
35% additional discount :
100% - 35% = 65% of item price will be paid
Hence, percentage of original price paid:
(55% * 65%) = 0.3575
= 35.75% of the original price is paid
