Answer:

36 ounces

Step-by-step explanation:

1 lb = 16oz

So just multiply 2 lb by 16 to get 32.

Then you can multiply 16 by 0.25 (a.k.a 1/4) OR divide 16 by 4

You get 4 ounces

Finally, add 32 and 4 to get your total of 36 ounces.

Answer:

Jack's fathers work is 1350 miles away from home

Step-by-step explanation:

Equation for trip 1:

Usual speed=x

Time=30 minutes

Formula for distance: d=st

d=30x

Equation for trip 2:

Speed= x-30

Time=90 minutes

d=90(x-30)

Now we solve for x using simultaneous equations:

30x=90(x-30)

x=45

Now to find d we sub in our new found value into one of the two equations (it doesn't matter which one)

d=30(45)

d=1350 miles

Answer:

$1,800,000 dollars

Step-by-step explanation:

Given the following question:

10% of 2,000,000

An app brought in $2 million in revenue before giving 10% of that revenue to pay for prizes. We need to find how much revenue did the app earn AFTER the store paid for the reward prizes.

[tex]\frac{10\times2000000}{100} =10\times2000000=20000000\div100=200000[/tex]
10% of 2 million is 200,000.

Using proportions, it is found that his total electricity cost for the fans during one year is given by:

b. $3.84

A proportion is a fraction of a total amount.

In this problem, for 3 months, he uses 4 portable fans, and each fan is on for about 96 hours per month, hence the total number of hours he uses it is:

4 x 96 = 384 hours.

The cost is one one cent per hour, hence:

$0.01 x 384 = $3.84.

Which means that the total cost is of $3.84, and option b is correct.

Step-by-step explanation:

love is = 4, because love + love = 8 meaning its 4+4

heart is = 5, because heart - 4(love) = 1

bird is = 3, because bear is = 9 since 5(heart) + 4(love) is bear, and 3 birds make  a bear.

Answer:

Answer:

ties cost $3

shirts cost $15

Step-by-step explanation:

s=shirts

t = ties

3 shirts and 5 ties cost $60:

3s+5t=60

2 shirts and 3 ties cost $39:

2s+3t=39

−2(3s+5t=60)

3(2s+3t=39)

−6s−10t=−120

6s+9t=117

add equations together:

−t = −3

t = 3

so ties cost $3, use either of the original equations to solve the price of shirts:

2s+3⋅(3)=392

s+9=392s=30

s=15

so shirts cost $15

Answer:

Tom should use a ladder that is smaller or at the the same height of the window frame. Here it says that he is using a ladder that is taller than the window frame, and this can be very uncomfortable for the person who is using the ladder, so it would be recommendable for Tom to use a smaller ladder, probably a ladder that is only a few inches smaller or taller than the window frame. Using a ladder that is like this should be safe to use.

Remainder theorem tells about the remainder of division of a polynomial with x - a. The roots of given function are: 1, -1, -3

If there is a polynomial p(x), and a constant number 'a', then

[tex]\dfrac{p(x)}{(x-a)} = g(x) + p(a)[/tex]

where g(x) is a factor of p(x)

For the given case, we've got:

[tex]f(x) = x^3 + 3x^2 -x - 3[/tex]

and

f(1) = 0

Thus, for a = 1, from remainder theorem, we get:

[tex]\dfrac{p(x)}{(x-a)} = g(x) + p(a)\\\\\dfrac{f(x)}{(x-1)} = g(x) + f(1)\\\\\dfrac{x^3 + 3x^2 - x - 3}{(x-1)} = g(x) + 0\\\\ \dfrac{x^2(x+3) -1(x+3)}{x-1} = \dfrac{(x^2-1)(x+3)}{(x-1)} = g(x)\\\\(x+1)(x+3) = g(x)[/tex]

Thus, the other factor of f(x) is g(x) = (x+1)(x+3)

And we have:

[tex]\dfrac{f(x)}{x-1} = g(x)\\\\f(x) = (x+1)(x+3)(x-1)[/tex]

Putting it equal to 0, we get:

[tex]f(x) = 0\\(x+1)(x+3)(x-1) = 0\\x = 1, -1, -3[/tex]

Thus,

The roots of given function are: 1, -1, -3
