Answer:
-9 1/4
Step-by-step explanation:
So what I did was that I put it this for which was -((5+3)+(3/4+1/2)
which then you would get -(8+(3/4+1/2)) which gives you -(8+5/4) because you would convert the 1/2 into 2/4 making it to get 5/4. So then you add the -(8+5/4) which gives you -9 1/4.
Hope this helped!

The slope of the line is: m = 1
Step-by-step explanation:
From the attached graph, we take the two points
(0, 5) (-5, 0)Now, determining the slope between the points (0, 5) and (-5, 0)
Slope = Rise / Run
Please also check the attached diagram to check Rise and Run.
so
[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\left(x_1,\:y_1\right)=\left(0,\:5\right),\:\left(x_2,\:y_2\right)=\left(-5,\:0\right)[/tex]

If a 18 ft tall statue casts a 12 ft Long shadow, then how long is the shadow that a 3 ft tall baby elephant casts
Answers
Answer:
2 feet
Step-by-step explanation:
This is because you have to use ratios:
18:12 :: 3:x
you can then figure out 18/12=1.5, so you have to figure out what what 1/1.5 or 2/3 of what 3 is. you then multiply 3 by 2/3 and get 2 feet
Answer:
2 ft
Step-by-step explanation:
use cross multiplication
12 is to 18 as x is to 3
12 / 18 = x / 3
12 × 3 = 18x
now solve for x
36 = 18x
divide by 18
2 = x
So a 3 ft baby elephant casts a 2 ft shadow

Which best represents the amount of water in the bottle that she did not drink?
Answers
Answer:
D. 13/20
Step-by-step explanation:
She did not drink 65/100, so you simplify that and you get 13/20
Answer: 13/20
Step-by-step explanation:
This question is based around conversions; you should know how to convert between percentages and fractions.
The question says that Lakisha drank 35% of the water contents. This means that she did not drink 65% (100% - 35% = 65%)
Now here is where the conversion comes in.
65% as a fraction is 65/100.
However, this isn't an option, so you have to simplify the fraction by dividing by 5.
65 / 5 = 13
100 / 5 = 20
Therefore, the answer is 13/20

to be added to complete that work in
12 days. (Ans-5 workers)
Answers
Answer:
5 more man should be added
Step-by-step explanation:
Inverse Proportion
The time needed to complete a job is inversely proportional to the number of men working on it.
It means the more men working, the less time needed to complete the job.
We know 20 men can complete the job in 15 days. If the job must be completed in 12 days, then more men are needed, thus the number of men needed is:
[tex]20*\frac{15}{12}=\frac{300}{12}=25[/tex]
25 men are needed which means 25-20 = 5 more men should be added.
5 more man should be added

Given
y = [tex]\frac{1}{(3x^2+1)^3}[/tex] = [tex](3x^2+1)^{-3}[/tex] , then
[tex]\frac{dy}{dx}[/tex] = - 3[tex](3x^2+1)^{-4}[/tex] × [tex]\frac{d}{dx}[/tex] (3x² + 1 )

Step-by-step explanation:
-w/6 + 9 = 2
subtract 9 from both sides
-w/6 + 9 - 9 = 2 - 9
-w/6 = 2 - 9
-w/6 = -7
multiply both sides by -6
-w/6 * -6 = -7 * -6
w = -7 * -6
w = 42
A car averages 28.5 miles per gallon of gasoline. How many liters of gasoline will be needed for a trip of 415 km? Some conversion factors that may be helpful are the following:
Answers
Answer:
34.22 liters
Step-by-step explanation:
Step one:
Given data
A car averages 28.5 miles per gallon of gasoline
How many liters of gasoline will be needed for a trip of 415 km
let us convert 415km to miles first
1 km is 0.621371 miles
415km is x miles
cross multiply we have
x= 415*0.621371
x=257.86 miles
Step two:
if 1 gallon of gasoline will cover 28.5 miles
the x gallons will cover 257.86 miles
cross multiply we have
28.5x= 257.86
divide both sides by 28.5
x= 257.86/28.5
x=9.04 gallons
Step three:
let us convert gallons to liters
1 gallon is 3.78541 liters
9.04 gallons will be x liters
cross multiply we have
x=9.04*3.78541
x= 34.22 liters
