Answer:
Step-by-step explanation:
For shirt :
Original cost = $54
New cost = $18
Change amount = 54 - 18 = $36
% INC/DEC = (36 /54) * 100 = 2 * 100 / 3 = 66.66%
For PS4 :
Original cost =$400
New cost = $250
Change in amount = 400- 250 =$150
% INC/DEC = (150/400) * 100 = 37.5%
For Coffee maker:
Original cost = $30
New cost = $20
Change in amount = 30 - 20 = $10
% INC/DEC = (10/30)*100 = 33.33 %
For Luggage:
Original cost = $180
New cost = $50
Change in amount = 180 - 50 = $130
% INC/DEC = (130/180)*100 = 72.22 %

A school paid $45.00 for 8 toothbrushes and 4 tubes of toothpaste. If each tube of toothpaste cost $4.50, how much did each toothbrush cost? Round to the nearest cent.
Answer:
$3.38
Step-by-step explanation:
The formula is 45= 8x + 4t. Each tube of toothpaste is 4.50, so times four is 18. So they spent 18 dollars on toothpaste, and the rest on toothbrushes. There are 27 dollars left, and 8 toothbrushes, so divide and each toothbrush is $3.375, or $3.38
Answer:
$3.38 PLEASE GIVE BRAINLIEST
Step-by-step explanation:
4.50(4) + 8x = $45.00
$18 + 8x = 45.00
8x = 45 - 18
8x = 27
x = 27 ÷ 8
x = 3.375 rounded to nearest cent is $3.38
Either Table L or Table M shows a proportional relationship. (Table L) - X -1,0,1,2 and Y= -2,0,2,4. (Table M- )X= -1,0,1,2, and Y= -4,0,6,9. Plot the points from the table that shows a proportional relationship.
Answer: Table L shows a proportional relationship.
Step-by-step explanation:
in table L, the ordered pairs are: (-1,-2),(0,0),(1,2),(2,4)
in table M, the ordered pairs are: (-1,-4),(0,0),(1,6),(2,9)
Notice that in table L, the increment for x values is consistent which is adding 1 and the increment for y values is consistent too which is adding 2. That's why table L is proportional.
In table M, the increment for x values is 1 but there is no consistent increment for y values.

Step-by-step explanation: My answer would be 36.To figure this out,list all the multiples of 6,9,and 12.Once you do that you have to see which numbers occur in all three.Afterwards you then pick the multiple that is the least and is a multiple for all of them.
Hope this help!!!!!!!!
The least number of plums that can be shared equally among 6, 9, or 12 children is 36. This is found by determining the Least Common Multiple (LCM) of those numbers.
Explanation:The subject of this question is math, specifically, it is about the concept of Least Common Multiple (LCM). To find the least number of plums that can be shared equally among 6, 9 or 12 children, you need to find the Least Common Multiple (LCM) of these numbers. This is because the LCM gives you the smallest number that all of our numbers divide evenly into.
Here's how you find the LCM of 6, 9, and 12:
Start by listing the prime factors of each number: 6 = 2 * 3, 9 = 3 * 3, and 12 = 2 * 2 * 3.Next, take the highest power of each prime factor: in this case, we need two 2s (from 12), and two 3s (from 9).Multiply these together to get the Least Common Multiple: 2 * 2 * 3 * 3 = 36.Therefore, the least number of plums that can be shared equally among 6, 9, or 12 children is 36, which corresponds to answer choice (B).

Which of the following is closest to 19.9 times 199?
A. 4000 B. 3990 C. 3980 D. 3970 E. 3960
you only get 30 seconds for this question so no straight out multiplying! (NO CALCULATORS EITHER) i think the distributive property is used but I don't know how so please help meeeeeeeeeeeeeeeeeeeeeeeeeeeeeee
Answer:
E 3960
Step-by-step explanation:
Round 19.9 and 199 to 20 and 200
20*200 = 4000
Now subtract 20
20 * (200-1) = 4000-20
20 * 199 = 4000-20
20*199 = 3980
.1 of 200 is 20
so subtract 20
(20-.1) *200=3980-20
19.9 *200 =3960
(20-.1) *(200-1) = 3960
Divide.

Answer each question. What is 35% of 90x? What percent of 16x is 9x?
Answer:
35% of 90x = 31.5
16x is 9x =
Step-by-step explanation:
35 /100 x 90 = 31.5
Answer:
31.5x; 56.25%
Step-by-step explanation:
For the first question:
We can write 35% as 0.35; this is because 35% = 35/100 = 0.35. Taking a percentage of a quantity means we multiply; this gives us
0.35(90x) = 31.5x
For the second question:
To find the percentage the second quantity is of the first one, we divide:
9x/16x = 0.5625
This is the same as 56.25%.
which of the following is not true in a dialation?
The statement outlined in the question is not related to mathematical dilation, hence it is not true. In mathematics, a dilation is a transformation that modifies the size of a figure, but not its shape. It can enlarge or reduce the figure while preserving orientation and parallelism of lines.
Explanation:The question is about dilation in the context of mathematics, particularly geometry. Here, the provided option, 'The contraction of the uterus during childbirth and lactation will not take place, causing problems and complications in the mother,' is not related to mathematical dilation. So, the statement is not true in a dilation.
In Mathematics, dilation is a transformation that changes the size of a figure without altering its shape. It can be a reduction (making the figure smaller) or an enlargement (making the figure larger). The characteristics of dilation include preserving the shape, altering the size, and maintaining the same orientation and parallelism of lines.

The grill was regularly priced at $58, but Jared had a coupon for 25% off. How much money did Jared save by using his coupon?
Answer:
He saves $14.50
Step-by-step explanation:
We can find the discount by multiplying the price by the percentage off
58* .25 = 14.50
He saves $14.50
Answer:
14.50
Step-by-step explanation:
You are not asked for the final price. You are asked for the amount saved. Don't confuse the two.
If he gets 25% off then you multiply (25/100) times 58 to get the amount saved.
(25/100) * 58 = 14.50
So his reduction is $14.50

Ramon bought a bicycle for $478. The value of the bicycle is expected to decrease at a rate of 6.5% each year. Which function equation represents the value of the bicycle after t years? f(t)=478(0.935)^t
f(t)=478(0.065)^t
f(t)=478(6.5)^t
f(t)=478(1.065)^t
Answer:
Correct choice is A
Step-by-step explanation:
Note that 6.5% is 0.065 as decimal.
Ramon bought a bicycle for $478. The value of the bicycle is expected to decrease at a rate of 6.5% each year, then the function that represents the situation is
[tex]y=478\cdot (1-0.065)^t=478\cdot (0.935)^t,[/tex]
where t is time (in years).
Options C and D are false, because functions are increasing, option B is false, because this function represents how much will the value decrease.
Answer:
The correct answer is A
f(t)=478(0.935)^t
which is the shorter drive in hours? Allentown to Gettysburg at 55 mph Philadelphia to Gettysburg at 65 mph Reading to Gettysburg at 40 mph
Answer:
Philadelphia to Gettysburg.
Step-by-step explanation:
For Allentown to Gettysburg, the drive is
1hour= 55m
1m = [tex]\frac{1}{55}[/tex]hour
= 0.018 hour
For Philadelphia to Gettysburg, the drive is
1 hour = 65m
1m = [tex]\frac{1}{65}[/tex]hour
