Answer:

marque sans cervelle

Step-by-step explanation:

Answer:

0.47 cm, 0.3 cm, 0.11 cm, or 0.55 cm

Step-by-step explanation:

Well, the question doesn't have a mathematical sign, like addition or subtraction, so I did all of the possible signs.

Addition: 2.5 + 2.2= 4.7 mm; converted to cm= 0.47 centimeters

Subtraction: 2.5-2.2= 3 mm; converted to cm= 0.3 centimeters

Division: 2.5/2.2= 1.1 mm; converted to cm= 0.11 centimeters

Multiplication: 2.5 * 2.2= 5.5 mm; converted to cm= 0.55 centimeters

Or, is the question asking to only convert 2.5 mm and 2.2 mm to centimeters?

In that case, the answers are 2.5mm= 0.25 centimeters; 2.2 mm= 0.22 centimeters.

(7x + 11y) - (5x + 6y)

(13x + 12y) - (6x + 2y)

(8x + 8y) - (4x - 2y)

Answers

Answer:

7xy + 6y + 6xy is a polynomial who’s like terms are 7xy and 6xy. Therefore, this polynomial can be simplified by combining like terms as 7xy +6xy +6y = 13xy + y. When combining like terms, we only add or subtract the coefficients of the identical variables.

On the other hand, unlike terms are terms which are not identical in terms of either variables or exponents.

For example, an expression 4x + 9y2, contain unlike terms because variable x and y are different and are not raised to the same power.

Answer:

1.

7x+11y-(5x+6y)

7x+11y-5x-6y

2x+5y

The probability of winning money on a particular ''scratch and win'' ticket is said to be 3 out of 10. If mrs. curcio buys 25 tickets to hand out to her students, how many of those would you predict to be ''winners''?

Answers

Answer:

8/25

Step-by-step explanation:

The total amount of tickets is 25 so divide 10 from 25 to figure out what you multiply by to get 25

--> 25/10 = 2.5

now multiply 2.5 x 3 to have a numerator which would be your probability of winners out of 25 tickets

--> 2.5 x 3 = 7.5 (round to the nearest whole number)

7.5 rounded to the nearest whole number --> 8

so you get 8 out of 25 = 8/25

Analyze the following data: 3, 14,14, 16, 17, 19, 21, 24


If the outlier is removed, what is the range?

A) 10
B) 12
C) 21
D) 18

Answers

Answer:

10

Step-by-step explanation:

The outlier is 3, so remove that. Then do 24-14 and you get 10.

Since the outlier is the least-fitting number in the data set, your outlier would be 3 since it is the farthest away from the rest of the numbers. You would be left with 14, 14, 16, 17, 19, 21, and 24. To find the range of the new data set you take the smallest value minus the largest value.

In conclusion, your answer is A) 10.

You'd have to find the length of C using the Pythagorean theorem.
So 15^2 + 8^2 = c^2
64 + 225 = c^2
289 = c^2
find the square root of each side
17 = c
You then add each side 15 + 8 + 17 which equals to 40 so 40 miles total !!

HELP PLSSSSSS PLS PLS IT WILL MEAN A LOT

Answers

Answer:

g = -25

t = -5

d = 9

Step-by-step explanation:

its a two step equation meaning you have to reverse the formula. For example, the first problem 1/5g + 8 =3. The first thing you would want to do is to subtract 8 from 3 because since 8 started out with addition, you have to reverse it into subtraction. so 3 - 8 = -5. Next step is to get the "g" by itself. Now since 1/5g is in multiplication form, we have to reverse it to division in order for the 1/5 to cancel out and to get "g" by itself. So then finally you do -5 ÷ 1/5 = -25. g = -25. so the answer is -25.
