Answer:

12

Step-by-step explanation:

13 + 6 + 2x -18 = 4x - 29

19 + 2x -18 = 4x -29

2x + 1 = 4x - 29

30 = 2x

15 = x

CD = 2(15) -18

CD = 30 -18

CD = 12

Misty must pack 365 candles into 15 boxes. Each box must contain an equal number of candles. How many candles does she have left
olganol [36]

The answer is 5 because you can fit 365 into 15 24 times and then that would equal 360 and then you have 5 left over.

15x24=360             365

                              -  360

                                 ____

Which of the following quotients are negative? Check all that apply. 1: 2.2 ÷ 9.5 2:–0.5 ÷ 0.021 3: –1.3 ÷ –54.321 0.4 ÷ –0.4 4:
german
We can already tell if a quotient is negative if the divisor or the dividend is a negative number. (Only 1 negative number and 1 positive number, because if there are two negative numbers then the outcome will be a positive.)

Question 4 has one negative number in it so it's already visible that the quotient is already negative. And if we did divide it the answer will be -1.

Question 3 has two negative numbers so we know that the outcome is a positive number. If solve the quotient is 0.023931813 which is clearly not a negative number.

Question 2 has one negative number so the answer will be negative. The quotient will be -23.80952381, which is clearly a negative number.

Question 1 doesn't have any negative numbers so the outcome will also be a positive number. The quotient for question 1 is 0.231578947.

So questions 2 and 4 both have negative quotients. While, questions 1 and 3 have positive quotients.

The probability that Maria succeeds at any given free-throw is 75%. She was curious how many free-throws she can expect to succe
Illusion [34]

Answer:

5: 0 successes

6: 5 successes

7: 8 successes

8: 6 successes

9: 6 successes

10: 1 success

We need to use her results to estimate the probability that she succeeds at fewer than 7 free-throws in a sample of 10 free-throws.

First, find out how many successes were less than 7 (out of 25), which is 5.

now, we divide 5 by 25 (5/25, formula being number/total attempts) and simplify into a decimal, which comes out to 0.2

how many miles apart are two cities that are 3 1/2 - inches apart on Raymond's map?

F. 12

G. 48

H. 96

J. 132

K .168

Step-by-step explanation:

Given;

1/4 inch = 12 miles

3 1/2 = 7/2 = 14/4 inch

number of 1/4 inch in 14/4 inch is;

14/4 ÷ 1/4 = 14

14/4 inch = 12×14 miles = 168miles

There is a pair of parallel sides in the following shape.
Nutka1998 [239]

The area of the shape is 12 square units

<h3>Area of a trapezium</h3>

The given shape is a trapezium and the formula for calculating the area of a trapezium is expressed as:

A = 0.5(a+b)h

Given the following parameters

a = 2

b = 10

h = 2

Substituting the given parameters

A = 0.5(2+10)*2
A = 0.2(12) * 2

A = 12 square units

Hence the area of the shape is 12 square units
