Answer:

30% and $30

Step-by-step explanation:

Well  240-168 is 72

72 is  30 percent of 240  because

240* x/100 = 72

24000x=7200

x=.3

.3 is percentage is 30%

We can check by doing

240*.3= 72

there is a 30% decrease

Next question

If the total price of something is 31.20 with a 4% tax we do

x * .04 + x = 31.20

because 4% added to the price of that object is 3.20

1.04x = 31.20

x= 30

we can check by doing

30*.04+ 30= 31.2

Answer:

mia

Step-by-step explanation:

mia: 10/6 per minute

shawn: 5/4 per minute

common denominator is 12, multiply by 2 and 3

20/12 lap per minute mia

15/12 laps per minute shawn

20 > 15

Answer:

1.3/4 × 2/2 = 6/8

2.3/4 × 3/3 = 9/12

3.3/4 × 4/4 = 12 /16

4. 3/4 × 5/5 = 15/20

Answer:

x=13

Step-by-step explanation:

62+(4x+7)+(6x-5)+41+(3x+6)+(7x-11)=360

62+4x+7+6x-5+41+3x+6+7x-11=360

100+20x=360

20x=360-100

20x=260

x=260/20

x=13

Answer:

c: 70

Step-by-step explanation:

Answer:

70%

Step-by-step explanation:

To find the percentage, we divide the number by the total.

The amount of people who said they'd buy it again is 1260, and the total is 1800.

1260/1800=0.7.

This means that 70% were satisfied with the car.

Answer:

70% you just take the amount of people that were satisfies divided by the overall amount of people. you'll get e decimal but just move the decimal place to get the percent.

Answer:

Step-by-step explanation:

c=180-123=57

b=180-123=57

d=180-57-55=68

a=180-68-57=55

a,b,c,d=55, 57, 57, 68 degrees

Answer:

Hello!

A parallel line must equal 180 degrees. Thus, 6y plus 120 degrees must equal 180. First, subtract 120 from 180. This gives us 60. To find y, we divide 60 by 60. This gives us 10. So, our answer is y=10. This means that y is being multiplied 6 times to equal 60.

Step-by-step explanation:

Let, x^a =y......(1) and

y^b =z.....(2) and

z ^c =x......(3).

Now, using (1) in (2) we get,

x ^ab =z......(4).

Now, using (4) in (3) we get,

x ^abc =x

or, x ^abc =x ^1

or, abc=1.

Answer:

AB = 25 units

Step-by-step explanation:

In right triangle ACB, [tex] CD\perp AB[/tex]

Therefore, by geometric mean property:

[tex]CD^{2} ={AD\times DB} \\ \\ {10}^{2} = AD\times 5 \\ \\ 100 = 5AD \\ \\ AD = \frac{100}{5} \\ \\ AD = 20[/tex]

AB = AD + DB

AB = 20 + 5

AB = 25 units

Answer:

The answer is A and C

Step-by-step explanation:

The answer is A because 12.3 multiplied by 10 is 123, and 0.4 multiplied by 10 is 4.

12.3 * 10 = 123

0.4 * 10 = 4

So, this shows that this equation is the same as 12.3 divided by 0.4

The answer is C because 12.3 multiplied by 100 is equal to 1230, this is the same for 0.4

12.3 * 100 = 1230

0.4 * 100 = 40

So, the answer is both A and C.

Hope this helps! :)

Answer:

12.3 divided by 0.4 is 30.75

Step-by-step explanation:

You then go to letter A and 123/4 is also 30.75

but you go through the rest of the choices just in case.

B is 3.075 so that is incorrect

C is 307.5 so that is also incorrect

D is 3075 and that is incorrect and not 30.75.

Therefore your answer is A.

30.75 = 30.75.

Hope this helps :)

Answer: I don't know/ A. f(n) = 4 + 60n

60+4n=cost. Because the number of children is multiplied by the cost for each child

i would say f(n)=60 +4n but i am probably wrong

Step-by-step explanation: other brainly's

f(n) = 4n + 60...or f(n) = 60 + 4n

f(n)=60+4n that is the correct answer!!!!!!

Answer:

A- The distribution of differences between the sample means of each group has a mean at or near zero making it likely the two groups are not statistically different.

Step-by-step explanation:

The distribution of both the red and blue is identical although the skewness differs slightly. The distribution of the two groups is identical and their mean is near to zero. The distribution of observation of the group provides clear view that these two groups are not statistically different.

The correct statements regarding the diagram include all the statements except: △RWS ≅ △UWT by AAS.

Given the image attached below, let's analyze each of the options given to determine whether they are correct or not.

Statement 1 is correct because based on reflexive property, ST in ΔRST is congruent to ST in ΔUTS.

Statement 2 is also correct because ∠RWS is vertically opposite to ∠UWT, so they are vertical angles.

Statement 3 is also correct because ΔRWS and ΔUWT have two pairs of congruent angles (∠SRW ≅ ∠TUW and ∠RWS ≅ ∠UWT) and one pair of non-included congruent sides (SR ≅ TU).

Statement 4 is incorrect because ΔRST and ΔUST do not have a pair of included congruent angles to meet the SAS Congruence Criterion.

Statement 5 is correct because since ΔRWS ≅ ΔUWT, ∠WTU ≅ ∠WSR based on the CPCTC theorem.
