Answer:

D. -4

Step-by-step explanation:

Answer:

1800.

Step-by-step explanation:

If N is the first letter the next 2 letters will be the number of permutations of 2 from 25 =  25!/ (25-2)!

= 600.

If the first number is M or P the number is the same so that makes 1800 possibilities.

Answer:

1,000ML = 1 L

4,500MG = 4.5G

25CM = 250MM

[tex] \frac{31.20}{4.8} = \\ [/tex]

[tex]6.5[/tex]

Thus the cost of steaks per pound is $ 6.5

Easy peasy....

The cost per pound of steaks is $6.5.

One type of operation in mathematics is division. We divide the phrases or numbers into the same number of components during this operation.

Given, a 4.8 pound box of steaks costs $31.20.

To find the cost per pound of steak:

We take the division of total cost and total pounds in weight.

That means,

Cost per pound of steaks

= 31.20 / 4.8

= 6.5.

Therefore, the cost is $6.5 per pound of steaks.

Answer:

49/101 minutes

Step-by-step explanation:

Your first part is correct the estimate will be 30 minutes because 5 miles divided by 10 miles per hour = 1/2 hours which is 30 minutes.

To solve the second part you need to use the numbers given first so 4 9/10 divided by 10 1/10. I find it easier to do improper fractions in this type of problem so I will do 49/10 divided by 101/10. Now you have to divide. The steps for dividing fractions are

1)Keep the First Fraction the Same.

2)Flip the second fraction over

3)Change the sign to multiplication

After the steps you will get 49/10*10/101

The denominator of the first fraction and the numerator of the second share a factor so you can cross them out. The factor they share is 10 and both numbers are ten so you can cross them out to one. Now you have 49/1*1/101

Since 49 and 101 don't share any factors you can now multiply. You get 49/101.

Answer:

174 m^2

Step-by-step explanation:

9 * 5 = 45

9 * 5 = 45

9 * 3 = 27

9 * 3 = 27

5 * 3 = 15

5 * 3 =15

45+45+27+27+15+15 = 174 m^2

Hope this is helpful.

Answer:

174 m²

Step-by-step explanation:

9 * 5 = 45 (that's the bottom and top areas)

9 * 3 = 27 (that's both the bigger sides areas)

5 * 3 = 15 (that's both the smaller sides areas)

Now  you have to double:

45 * 2 = 90

27 * 2 = 54

15 * 2 = 30

Now sum:

90 + 30 + 54 = 174

n = {-1, 7}

Step-by-step explanation:

8n² - 56 = 48n

Subtract 48n from both sides

8n² - 48n - 56 = 0

Divide both sides by 8

n² - 6n - 7 = 0

We have that for the Question "I know how to apply the midpoint theorem, but I don't know where I should start my intervals." it can be said that

Where you start your intervals are at the (x,y) co-ordinate of the Reference points

From the question we are told

I know how to apply the midpoint theorem, but I don't know where I should start my intervals.

Generally the equation for the midpoint   is mathematically given as

[tex]m=\frac{x1+x2}{2},\frac{y1+y2}{2}[/tex]

Naturally the midpoint of two point is the point in between the reference points where distances from them are equal

Therefore

Midpoints co-ordinates simply considers the co-ordinate of the two main reference points.(x,y)

Hence

Where you start your intervals are at the (x,y) co-ordinate of the Reference points

Answer:

$15,000

Step-by-step explanation:

Let P represent Aiden's current pay.

If they receive a pay rise of 15%, that means they receive their original pay plus 15% of that original pay.

P + 0.15P = 17250

1.15P = 17250

P = 17250/1.15 = 15000

His salary before the increase was $15,000.

Answer:

$14662.5

Step-by-step explanation:

Aiden receives a pay rise of 15%

increases their pay to $17,250

15% of $17,250 is $2587.5 therefore $17,250 - $2587.5 is his salary before the increase which is 14662.5 so aiden had $14662.5 before his salary increase
