Answer:

Below,...

Step-by-step explanation:

1) = 0.67 (0.25 + 0.42 = 0.67)

2) = 0.20 (0.04 + 0.16 = 0.20)

3) = 0.84 (0.50 + 0.34 = 0.84)

4) = 1.21 (0.92 + 0.29 = 1.21)

5) = 0.42 (0.70 - 0.28 = 0.42)

6) = 0.51 (0.64 - 0.13 - 0.51)

7) = 1.15 (1.40 - 0.25 = 1.15)

8) = 0.75 (1.68 - 0.93 = 0.75)

9) = 0.25 (0.10 + 0.15 = 0.25)

10) = 0.35 (0.80 - 0.45 = 0.35)

11) = 1.32 (0.60 + 0.72 = 1.32)

12) = 1.34 (1.70 - 0.36 = 1.34)

Answers

Answer:

7.99- no

8.162- no

8.074- yes

8.13- yes

8.012- no

Step-by-step explanation:

7.99 to the nearest tenth = 8.0

8.162 to the nearest tenth= 8.2

8.074 to the nearest tenth=8.1

8.13 to the nearest tenth=8.1

8.012 to the nearest tenth=8.0

When rounding to the nearest tenth look at the place after it. If it is less than five then the number in the tenth will be rounded to 0. However if the following digit is 5 and above, 1 is added to the number you are rounding.

Answers

Answer:

the answer will be 4x²...last option

Answer:

Answer is 4x² = 36

Step-by-step explanation:

Let that number be x:

[tex]4 \times x {}^{2} = 36 \\ {4x}^{2} = 36[/tex]

further more:

[tex] {x}^{2} = \frac{36}{4} [/tex]

take a square root:

You invested $20,000 in two accounts paying 7% and 8% annual interest, respectively. If the total interest earned for the year was $1530, how much was invested at each rate?

Answers

Answer:

$7,000 at 7%; $13,000 at 8%
