Which expression is equivalent to -6.5 - 5.1 + 2.3c - 1.8

Answer:

$9

Step-by-step explanation:

20% is equal to 1/5. Multiply $45 by 1/5 to get $9

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:

$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.
[tex]2000000-200000=1800000[/tex]

The app earned "$1.8 million" after paying for the reward prizes.

Hope this helps.

Answer:

The width of the actual pool is 12 meters

Step-by-step explanation:

You can put Kiara's scale into a ratio or fraction to help visualize it better: 13/6. Now, let's put what we do know for the other ratio into a fraction. we know that the pool is 26 centimeters wide, and since the 26 matches with the 13, that goes in the numerater. since we don't know the denominator, we can just put 26/x (you can use whatever letter you like but I'll use x here)

So in order to get 13/6 to 26/x, we need to find how to figure out what we are doing to the original fraction. Since 13 x 2= 26, it looks like we are multiplying the ratios by 2. Now that we know that, we can multiply the denominator (6) by 2 to equal 12, our answer.

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

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:

3s + 5t = 60 and 2s + 3t = 39

Answer:

A farmer keeps a record of the weekly milk yield of his herd of seven cows over a period of six months. He finds that the mean yield is 24 liters. He buys another cow that he is told will produce 28 liters of milk a week. Work out the effect this will have on the mean milk yield of his cows.​

Step-by-step explanation:

Hope it helps<3

Answer:

24.5 liters/week

Step-by-step explanation:

24 liters/week for 7 cows is 168 liters/week

Add 1 cow that produces 28 liters/week

The new total is 196 liters/week for 8 cows

(196 liters/week for 8 cows)/(8 cows) = 24.5 liters/week is the new mean.

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.

Hello there !

I will be glad to help you since I already studied this!

So,  the angles that will always be equal to each other formed by a transversal even in solving equations are, corresponding angles, alternative interior, and alternative exterior. Refer to the attachment for visual understanding

Vocabularies: Transversal -  transversal is a line that intersects two or more other (often parallel ) lines.

Include to this there are consecutive interior angles and for a tip, for example, you see an equation with consecutive angles add the two angles and make them equal to 180 degrees in most cases.

Depending on your question they may give you angles with same lines on them so which means in most cases they are equal even if they don't seem equal

I forgot to inform you about vertical angles!

they are also congruent..refer to the attachment too

Supplementary angles are on a straight line.... AND equal to a sum of  180 degrees.. refer to the attachment as well

Answers:

1.  Yes - because they are vertical angles

2. No because none of the rules apply so it's not congruent

3. Yes- they are congruent

4. No because none of the rules apply...

5. No-No because they aren't adjacent and  adjacent angles add up to 180 degrees(Tip: adjacent angles are close to each other almost on the same side)

6. No- they are corresponding... they do now add up to 180 degrees

7. No

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

Answer:

Answer:

60 mph

Step-by-step explanation:

We calculate the combined distance travelled by the two trains in two hours.

As they were 500 miles apart at first, and 300 miles apart after, they have travelled 200 miles together.

I think the question means "one train travels 20 mph faster than the other".

Say the faster train has speed x mph. Then the slower has speed x - 20 mph.

Now, the combined distance travelled in 2 hrs is 2 * (x + x - 20) = 200

2x - 20 = 100

2x = 120

x = 60 mph

Function

d. 4f(t)

=4(t²+9)

=4t²+36

e. (f(t))²+8

=(t²+9)² + 8

= t⁴+18t²+81+8

= t⁴+18t²+89
