Find the elapsed time for a person who worked from:
11. 10:00 am to 7:00 pm
12. 5:45 am to 11:20 am
13.6:00 pm to 9:48 pm
Answer:
11. 9hrs
12. 5hrs 35min
13. 3hrs 48 min
Step-by-step explanation:
Makes it a bit easier if you convert to 24 hr time.
11. 10 - 19 is 9hrs
12. 545-1120 is 11-5 20-45 -> 6hrs -25min -> 5hrs 35min
13. 1800 - 2148 is 21-18 48-00 -> 3hrs 48 min
Answer:
11. 9h
12. 5h 35 min
13. 3h 48min
Step-by-step explanation:
11.
here,
time elapsed = ∆t = final time - initial time
= 7 pm - 10 am
= (12+7) h - 10 h {turn pm into am by adding 12 and converting both into hour and min}
= 9 h
12.
similarly,
time elapsed = ∆t = final time - initial time
= 11 h 20 min - 5 h 45 min
= 5 h 35 min
13.
similarly,
time elapsed = ∆t = final time - initial time
= 9 h 48min - 6 h
= 3h 58min

Answer:
[tex]9^{-16}[/tex]
Step-by-step explanation:
Whenever you are adding exponents that have the same base (in this case the base is 9), you simply add the exponents. The base will stay the same because you are just adding the exponents
[tex]-53 + 37=-16[/tex]
So, your answer is [tex]9^{-16}[/tex]

x + 9 = 18 + -2x what does x epual
Answer:
x = 3
Step-by-step explanation:
Step 1: Write out equation
x + 9 = 18 - 2x
Step 2: Add 2x on both sides
x + 2x + 9 = 18 - 2x + 2x
3x + 9 = 18
Step 3: Subtract 9 on both sides
3x + 9 - 9 = 18 - 9
3x = 9
Step 4: Divide both sides by 3
3x/3 = 9/3
x = 3

The bells are adding a new room to their house. The room will be a cube with volume of 4,913 feet cubed. They are going to put in hardwood floors, and the contractor charged $5 per square foot. How much will the j hardwood floors cost?
Answer:
$1445
Step-by-step explanation:
The side length of the room is the cube root of the volume of the cube:
s = ∛4913 = 17 . . . . feet
The area of the floor is the square of this side length:
A = (17 ft)² = 289 ft²
The cost of the floor is $5 for each square foot:
cost = ($5/ft²)(289 ft²) = $1445
The hardwood floor will cost $1445.

PLEASE HELP ASAP!! Ben worked 6 hours at x dollars per hour. Julie worked 9 hours and earned twice as much as Ben per hour. Phil worked 16 hours and earned 3 dollars an hour less than Julie. Choose the expression that is correctly simplified and best represents their total wages. A. 56x – 48 B. 40x – 48 C. 31x – 3 D. 40x – 3
Answer:
A
Step-by-step explanation:
Given that Ben worked 6 hours at x dollars per hour. That is,
Ben earns = 6x
Julie worked 9 hours and earned twice as much as Ben per hour. That is,
Julie earns = 9 × 2x = 18x
Phil worked 16 hours and earned 3 dollars an hour less than Julie
That is,
Phil earns = 16 × ( 2x - 3 )
= 32x - 48
Total wages = 6x + 18x + 32x - 48
Total wages = 56x - 48
Option A is therefore the best option which is the answer to the question.

solve the equation below for x
2/3(x-18y)=6y
Answer:
[tex]x = 27y[/tex]
Step-by-step explanation:
[tex]\dfrac{2}{3}(x - 18y) = 6y[/tex]
Multiply both sides by 3/2.
[tex]\dfrac{3}{2} \times \dfrac{2}{3}(x - 18y) = \dfrac{3}{2} \times 6y[/tex]
[tex]x - 18y = 9y[/tex]
Add 18y to both sides.
[tex]x = 27y[/tex]
Answer:
x=27y

What is the slope of the line that goes through the points (-15, 70) and (5, 10)?
Question is given in picture below. Help will be greatly appreciated!
Answer:
C
Step-by-step explanation:
Th explicit formula of a geometric sequence has the following format:
[tex]x_n=a(r)^{n-1}[/tex]
Where a is the initial term and r is the common ratio.
From the recursive formula, we can see that each subsequent term is multiplied by 13. Thus, the common ratio is 13.
Also, we are given that the first term is 7.
So, substituting these in, we have:
[tex]x_n=7(13)^{n-1}[/tex]
Our answer is C

An adult usually has 32 teeth. People sometimes lose some of their teeth. Pat has only 5/8 of her teeth left. How many teeth has she lost?
Answer:
twenty teeth
Step-by-step explanation:
32:8=4
4•5=20
Answer:
Pat has lost 12 teeth.
I got a calculator and divided 32 by 8, then timed that answer (4) by 3.
32 ÷ 8 = 4
4 x 3 = 12
If the question had asked how many teeth Pat has, the answer would be 20, but that isn't correct for this question. It asks how many teeth she has lost, and that would be 12.
hope this helps
