Answer:

2 n 3 − 5 m 2 + 10 n 2

Step-by-step explanation:

Answer:

- 10m + 26n

Step-by-step explanation:

2m × 2 - 7m × 2 + 10n × 2 + 2n × 3

4m - 14m + 20n + 6n

- 10m + 26n

Answer:

40 cubic units

Step-by-step explanation:

Answer:

5x<50

Step-by-step explanation:

Answer:

Step-by-step explanation:

5n < 50 <--- subtracts 4 from both sides

n < 10 <--- divides both sides by 5

Check: testing n=0, we have 4 + 5(0) = 4 + 0 = 4 < 54, so yes it works

testing n=10, 4 + 5(10) = 4 + 50 = 54.

testing n=11, 4 + 5(11) = 4 + 55 = 59 <--- fails as expected.

Step-by-step explanation:

Answer:

3/18 foot³

Step-by-step explanation:

okay, so the formula for volume is height x base, which is real confusing, but lets go:

first, you have to figure out the base, which is the surface that's on the bottom:

1/2 x 1/2 = 1/4

so you then multiply that by how high the figure is:

1/4 x 3/4 = 3/16

So your answer is option D. 3/18 cubic foot

hope this helps:)

Answer:

The expression that shows how many people ran in the race is 35 + 28 - 12 + 16 = X, and the number of people that ran is 67.

Step-by-step explanation:

Since during the first week of registration, 35 people signed up for the Health Fair 5K and Fun Run, and the next week, 28 more people signed up, and on the day of the race, 12 runners did not show up but, however , at the last minute 16 people came in for late registration, to determine which expression shows how many people ran in the 5K and Fun Run and determine said amount, the following calculation must be performed:

35 + 28 - 12 + 16 = X

79 - 12 = X

67 = X

Thus, the expression that shows how many people ran in the race is 35 + 28 - 12 + 16 = X, and the number of people that ran is 67.

Answer:

y=-3x-2

Step-by-step explanation:

Equation of a line is y=mx+b, where m is the slope given, -3.

Y=-3x+b

To find b, sub in the points (-3,7) for x and y in the equation

7=-3(-3)+b

7=9+b

-2=b

Step-by-step explanation:

1a)you are asked to find the number of girls and boys who received prizes

1b)The given facts are that out of 60 pupils, 40 being boys, 20 being girls, joined a Math Quiz competition. 20%of boys and 15 of girls received prizes.

1c)40 boys +20 girls=60 pupils.

1d) Find the number of girls and boys that re ceived prizes

20% of 40 boys

20/100 ×40= 8 boys won prizes

15% of 20 girls

15/100×20=3 girls won prizes

1d) 8 boys+3 girls=11 pupils won prizes

Answer:

-4x + 5y = 40

Step-by-step explanation:

- move the expression to the left, so you want to get y - 4/5x = 8

-  multiply both sides so you get 5y - 4x = 40

- reorder the terms so you get -4x + 5y = 40

personally, I would change the signs afterwards to get 4x - 5y = -40, but the last thing I wrote was what was shown in that picture you sent. hope this helped :)

Answer:

C) sinF=27/45

Step-by-step explanation:

Because both triangles are similar, that means their sides are proportional to each other. Since sin∅=opposite/hypotenuse, then if sinC=3/5, we must find a ratio that is proportional to 3/5. Option C seems to work because 27/45=3/5, so sinF=27/45

Answer:

15

Step-by-step explanation:

Multiply: 25x.60=15

The reason why you multiply 25 times .60 is because you need to change the percentage to a decimal. The way you change you from a percentage to a decimal is by moving the decimal twice to the left.

So, 60%=.60

Answer:3

Step-by-step explanation:

Answer:

Step-by-step explanation:

Okay, so this is impossible to tell the amount of spaces, but let's say it was 4000 for VIP and 4000 for Popular Stands. Multiply $30 by 4000, and you get $120k Earnings. To check your answer, Divide 120,000 by 4000, and you get $30 for each stand.

Now, let's move on with the VIP stands. A VIP Stand costs $50, so 4,000 x $50 = $200k earnings. To check your answer, divide 200,000 by 4000, and you get $50 for each VIP Stand.

If you need to find each variant, go by 1k seat increments, i.e. 1000 and 7000, 2000 and 6000, etc.

Glad I could help!

Answer:

50%

Step-by-step explanation:

one question has 2 possible answers and 1/2 is 50%

Answer:

False ;

False ;

False

Step-by-step explanation:

In a perfectly symmetric distribution, the mean and Median values are the same. But for skewed distributon, the median is greater than the mean (negatively skewed or left skewed data). Hence, the assertion is false.

The sign of the correlation Coefficient does not give information about how good a line fits. The sign attached to the correlation Coefficient gives information about the slope and hence, the type of relationship between the variables.

Positive (+) sign = positive relationship between variables ; negative (-) sign = negative relationship between variables.

C.)

The value of the range is not always higher Than the value of the interquartile range. The IQR might have the same value as the value of the range.

For instance :

Given the data :

1, 1, 1, 2, 2, 3, 4, 4, 4

Range = maximum - minimum

Range = 4 - 1 = 3

Interquartile range (IQR) :

IQR = Q3 - Q1

Q3 = 3/4(n+1)th term

Q3 = 3/4(10) = 7.5th term

Q3 = (7th + 8th) / 2 = (4+4)/2 = 4

Q1 = 1/4(10) = 2.5th term

Q1 = (2nd + 3rd) / 2

Q1 = (1 + 1) /2 = 1

Q3 - Q1 = 4 - 1 = 3

Answer:

70%

Step-by-step explanation:

Given that,

Cost price of the stock = $2.98 per share

Sold price of the stock = $0.88  per share

We need to find the percent decrease in the stock. It can be done as follows :

[tex]\%=\dfrac{2.98-0.88}{2.98}\times 100\\\\=70.46\%[/tex]

or

= 70%

So, the decrease in the stock is equal to 70 %.

Answer:

10'800

Step-by-step explanation:

Car initial price= 12000

Depreciation= 10% or 0.10 per year

Car final price= Initial price-(Initial price/depreciation)

Car final price= 12'000-(1'200)

Car final price= 10'800
