8 0

Answer:

Kylee must get an 87 on her next test to raise her average grade to 80.

Step-by-step explanation:

Her previous tests average: 81+75+77=233

233÷3=<u>77.7</u>

If she gets a 87 on her next test, it averages: 81+75+77+87=320

320÷4=<u>80</u>

Answer:

35 degrees

42 degrees

x = 8 degrees

x = 7 degrees

Step-by-step explanation:

1)

m <1 = 70/2 = 35 degrees

2)

m <1 = 84/2 = 42 degrees

3)

6 + 4 x = (9 x + 4) / 2

12 + 8 x = 9 x + 4

12 - 4 = x

x = 8 degrees

4)

3 x - 1 = x + 13

2 x = 14

x = 7 degrees

Need help with number 2
Slav-nsk [51]
Luis is wrong because 8 to the third power is not 24, but is 512. He multiplied 8 by 3 instead of doing 8x8x8, so Luis made an incorrect claim.

Answer:

$154,763.5

Step-by-step explanation:

A = P(1 + r/n)^nt

Where,

A = future value

P = present value

r = interest rate

n = number of periods

t = time (years)

P = 97,000

r = 6% = 0.06

n = 365

t = 8 years

A = P(1 + r/n)^nt

= 97,000(1 + 0.06/365)^365*8

= 97,000(1 + 0.00016)^2,920

= 97,000(1.00016)^2,920

= 97,000(1.5955)

= 154,763.5

A = $154,763.5
