48 is 80% of 60

48 of 60 can be written as 48/60

Multiply both the numerator and the denominator by 100
48/60 · 100/100 = 80/100 = .8 = 80%

If you are using a calculator, simply enter 48 ÷ 60 · 100 which will give you 80 as the answer.

A FedEx treight truck carries three tons of packages 660 miles on 90 gallions of diesel fuel from Miami, FL. to Atlanta, GA. Fed

musickatia [10]

Ans(a):

Given that a FedEx freight truck carries three tons of packages 660 miles on 90 gallons of diesel fuel from Miami, FL to Atlanta, GA.

so that means speed of the truck is

speed = distance/time = 660/90 miles per gallon

hence slope of the equation will be

m=660/90 = 66/9= 22/3

There is no information about initial cost or any initial value so that means y-intercept b=0

plug value of m and b into y=mx+b

so we get equation y=22/3x+0

Where x is the number of gallons and y is the number of miles

Now we can easily graph this equation to get the required graph.

when x=0 then y=22/3x=22/3*0=0

so first point is (0,0)

when x=3 then y=22/3x=22/3*3=22

so second point is (3,22)

Now we join them by a line to get the graph

Ans(b):

clearly number of gallons can't be negative so domain is all positive real numbers.

Ans(c):

Origin of the graph represents that if there is no gallons of fuel used then there will be no distance traveled.

A realty company looks at a recent sample of houses that have sold On testing the nul hypothesis that 57% of the houses take mor

Murrr4er [49]

Answer:

The correct option is: If 57% of the houses take more than three months to sell, there is a 2 6% chance that a random sample proportion would be as high as or higher than the one they obtained

Step-by-step explanation:

Consider the provided information.

The Null hypotheses is 57%,

$H_0: \mu=0.57\\H_a: \mu>0.57$

P-value is given as 0.026

Here P value represents the probability.

0.026 can be written as: 2.6%

Thus the conclusion is:

If 57% of the houses take more than three months to sell, there is a 2 6% chance that a random sample proportion would be as high as or higher than the one they obtained.

Hence, the correct option is: If 57% of the houses take more than three months to sell, there is a 2 6% chance that a random sample proportion would be as high as or higher than the one they obtained

3/8(2x-8/3x)=21 solve the equation for x

mart [117]

Answer:

$\boxed{\bold{x=-84}}$

Explanation:

Multiply Both Sides By 8:

= $\bold{8\cdot \frac{3}{8}\left(2x-\frac{8}{3}x\right)=21\cdot \:8}$

Simplify:

= $\bold{-2x=168}$

Divide Both Sides By -2:

= $\bold{\frac{-2x}{-2}=\frac{168}{-2}}$

Simplify:

= $\bold{x=-84}$

Solve:<br> 2y + 5x=30<br> y = 3x + 4

mafiozo [28]

Replace the second equation y=3x+4 into the first one:
2(3x+4)+5x=30
Now solve for x:
6x+8+5x=30
11x=30-8
11x=22
x=22/11
x=2
Finally, replace x=2 into y=3x+4
y=3*2+4
y=6+4 = 10
So the anwer is x=2, y=10
