lana [24]

Answer:

1) 5×5×5

2) False

3) False

Step-by-step explanation:

5³ basically means 5 is multiplied thrice, i.e

5 × 5 × 5

4² = 4×4 = 16

4² is 16, not 8

(-3)² = -3 × -3 = 9

-(3)² = -9

If the average grade on an English class rose from 70 to 85 what is the approximate percent increase ?
mixer [17]

Answer: The approximate percent increase is 121.42857%. This is a rounded value. To get this, first you would need to find out which increased and in what direction. Of course, the 70 turned into an 85. So you can divide 85 by 70 and receive a number. Then in whatever form you found it, decimal, fraction, or even percent straight away, ensure the value is a percentage.

70 -> 85

85/70

About 1.21 [decimal]

1.21 x 100 = 121 [add the %]

121% [rounded]

Yesterday, the temperature at noon was 43.6 °F. By midnight, the temperature has decreased by 15.3 degrees. What was the tempera
ELEN [110]

Answer:

Temperature at midnight is -15.9 °F.

Step-by-step explanation:

Given: The temperature at noon was 43.6 °F. By midnight, the temperature has decreased by 15.3 degrees.

To find: The temperature at midnight.

Solution:

The temperature at noon was 43.6 °F.

Now, by midnight, temperature has decreased by 15.3 degrees.

So, first we need to convert the temperature in °F.

We know that, F=\frac{9}{5}C+32, where F is temperature in Fahrenheit and C is temperature in Celsius.

So, F=(\frac{9}{5} \times 15.3)+32  

\implies F=59.5

So, by midnight, temperature has decreased 59.5 °F

Therefore, temperature at midnight is 43.6-59.5=-15.9 °F

Hence, temperature at midnight is  -15.9 °F.
