Answer:

The answer is:

morning: 0c

afternoon: -5c

night: 3c

Step-by-step explanation:

Given that night temperature is 3c

and night temperature was 8c higher than the afternoon temperature

so 3c-8c = -5c

afternoon temperature was 5c lower than the morning temperature

so -5c +5c = 0c

Night = 3degree

Afternoon = 8degrees less than night (3degrees)
--> 3 – 8 = –5degrees

Morning = –5 Dregree more than the afternoon
--> –5 + 5 = 0degree

Slips of paper numbered 1 to 15 are placed in a box. A slip of paper is drawn at random. What is the probability that the number
monitta

Given:

Slips of paper numbered 1 to 15 are placed in a box.

To find:

The probability that the number picked is either a multiple of 5 or an odd number.

Solution:

We have,

Total outcomes = 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15

No. of total outcomes = 15

Multiple of 5 are 5, 10, 15.

Odd numbers are 1, 3, 5, 7, 9, 11, 13, 15.

Number that are either a multiple of 5 or an odd number are 1, 3, 5, 7, 9, 10, 11, 13, 15.

No. of favorable outcomes = 9

We know that,

\text{Probability}=\dfrac{\text{Favorable outcomes}}{\text{Total outcomes}}

\text{Probability}=\dfrac{9}{15}

\text{Probability}=\dfrac{3}{5}

\text{Probability}=0.6

Therefore, the  probability that the number picked is either a multiple of 5 or an odd number is 0.6.

Apply your knowledge of square roots to solve equations involving them. Show your step-by-step solution. Remember, each problem
Elena L [17]
Remember to include the positive and negative roots


(7x-2)^2=256
sqrt both sides
7x-2=+/-16
add 2 to both sides
7x=2+/-16
divdide both sides by 7
x=(2+/-16)/7)

x=(2+16)/7=18/7=2 and 4/7
x=(2-16)/7=-14/7=-2

x=2 and 4/7 or -2

Aliyah $24 to spend on seven pencils. After buying them she had $10. How much did each pencil cost?
MaRussiya [10]
Each pencil cost $2.

Explanation: She had $24 before buying the pencils and after she had $10. 24-10=14 so the total she spent on pencils was $14. She bought 7 pencils so you divide 14 by 7 (14/7=2) which equals 2. So each pencil cost $2.

Determine the explicit form of the function that describes the sequence below.
docker41 [41]

Answer:

C

Step-by-step explanation:

This is a geometric sequence with n th term

a_{n} = a (r)^{n-1}

Where a is the first term and r is the common ratio

r = \frac{24}{16} = \frac{36}{24} = \frac{54}{36} = \frac{3}{2}, hence

f(n) = 16 (\frac{3}{2}) ^{(n-1)} → C

Annabelle arranged her 42 building blocks into 3 rows of 14 blocks. Then, she rearranged them into 6 rows of 7 blocks. What two
cupoosta [38]

Answer:

21 rows 2 blocks

1 row 42 blocks

Step-by-step explanation:

Given that:

Number of blocks with Annabelle = 42

First arrangement = 3 rows 14 blocks

Second arrangement = 6 rows 7 blocks

To find:

The other two factor pairs that could be used to rearrange the blocks again?

Solution:

Here, we will have to find the factor pairs of total number of blocks present with Annabelle.

i.e. 42

First of all, let us have a look at the factor pairs of 42.

42 = 3\times 14\\42 = 6\times 7\\42 = \underline{2\times 21}\\42 = \underline{1\times 42}

Therefore, the other two factor pairs can be 2, 21 and 1, 42.

The other two possible factor pairs are:

21 rows 2 blocks

1 row 42 blocks
