Answer:

log 19 + log 42

Step-by-step explanation:

798 = 2* 3 *7*19

= 19 * 42

log 798 = log (19*42)

Now log ab = log a + log b

So:

log 798 = log 19 + log 42 <-- is equivalent to log 798.

If the volume of a cube is increased by a factor of 10 (so that the new volume is 10 times the size of the original volume), by

Alexeev081 [22]

Answer:

surface area of cube $10^{\frac{2}{3} }$ time

Step-by-step explanation:

given data

new volume = 10 time original volume

to find out

what factor surface area change

solution

we consider here side of cube is a

and volume is V

we consider here a is 2

then volume will be v1 = a³ = 2³ = 8

and surface area = 6a² = 6(2)² = 24 ..........1

so if volume increase 10 time

than

V = 10 × v1

a³ = 10 × 8

a³= 80

a = 2 × ∛10

and

surface area increase here

surface area = 6a²

surface area = 6( 2 × ∛10 )²

surface area = 24 × $10^{\frac{2}{3} }$ ............2

so from equation 1 and 2

surface area / surface area = 24 × $10^{\frac{2}{3} }$ / 24

surface area = $10^{\frac{2}{3} }$

so here surface area of cube will be $10^{\frac{2}{3} }$ time

Caroline replaced the original factory tires (P240/75 R 16) on her pickup truck with P290/70R16 tires. If the speedometer on Cas

Irina-Kira [14]

Answer:

Cassie is traveling 63.6 mph

Step-by-step explanation:

If the three numbers, left to right, are A, B, C, then the tire radius in millimeters is ...

A×B/100 + 12.7×C

For the factory tires, the tire radius is ...

240·75/100 + 12.7·16 = 180 +203.2 = 383.2 . . . . millimeters

For the replacement tires, the tire radius is ...

290·70/100 +203.2 = 406.2 . . . . millimeters

The speedometer is calibrated based on the number of revolutions the tire makes in a given time period. If the truck goes farther for each revolution, its speed is higher by the same proportion.

If the speedometer on the truck with these replacement tires reads 60 mph, the actual speed is ...

(406.2/383.2)×60 mph = 63.6 mph

_____

Comment on the problem statement

Caroline's truck has the replacement tires. If Cassie's speedometer reads 60 mph, we have no reason to assume Cassie is traveling at any speed other than 60 mph.

Oxana [17]

Joel's work makes $9.50/ hr. During the 2 Day, 11 hrs shift, he earns a total of $217.55 but spends a cash of $9 on his bus. Therefore, the money left is $208.55. While on his 4 day, 6 hrs shift, he earns a total of $228 but spends $18, with a total money of $210. The option that he should take to make the most money is the 4 days for 6 hrs shift.

Answer:

Linear

Step-by-step explanation:

If you graph this, you start at 1500 on the y-axis. Every time the x-axis increases by 1, the y-axis increases by 200. This forms a straight line, making it exponential since it increases by a constat amount.
