Answer:

5n - 10

Step-by-step explanation:

Put this in numerals and signs:

Ten less than the product of 5 and a number

10      -                     5n

We already have 10 and 5.

Less than means to subtract

Since we do not know what the "number" truly is, we can use a variable. I will choose the letter, n.

Product means to multiply, times, so that would be 5 times n, but we do not need the symbol, ×, because as long as it is next to the number, it means multiplication.

Since 10 is less than 5n, 5n is greater than 10, which means 10 would be behind the minus sign.

Therefore, the expression is 5n - 10

Answer:

Explanation:

The word "less" defines subtraction. This means that the minuend is 5a. and ten is the subtrahend.

Hence, the expression is 5a - 10.

Answer:

Yes because a multiple is a number that can be divided by another number without a remainder.

Step-by-step explanation:

54 divided by 9 equals 6

Answer: So you basically subtract 67 by 20% of it so that is

67-20%

Which is 53.6.

So the answer is $53.60

Answer:

The answer is $53.6

Step-by-step explanation:

Here,

67 × 20 ÷ 100 = 13.4

Now,

$67 – $13.4 = $53.6

Thus, The current price of the item is $53.6

Answer:

sin(y)=24/25

cos(y)=7/25

tan(y)=24/7

Step-by-step explanation:

We know sinФ=Opposite/Hypotenuse, cosФ=Adjacent/Hypotenuse, and tanФ=Opposite/Adjacent. We can remember this with SOH-CAH-TOA.

We know our angle is y. The Adjacent to y is 7. The opposite to y is 24. The hypotenuse is 25.

Now, we can plug the given information into the formulas in order to get the solutions.

sin(y)=24/25

cos(y)=7/25

tan(y)=24/7

Answer:

430 and 1/2 cubic inches

Step-by-step explanation:

Answer:

Step-by-step explanation:

The problem statement tells you the fixed cost is $1800. It is "fixed" because it does not depend on the number of cups sold.

The variable cost per cup sold is said to be $0.59, so the total variable cost for a week will be the product of that value and the number of cups sold.

Fixed and variable costs are added to get the Total Cost. Total cost is divided by the number of cups sold to get the Average Cost. A spreadsheet performs this math nicely. (See attached.)

__

If you consider the equation for average cost based on the above description, you see is its ...

  ac = tc/q = (fc +vc)/q = (1800 + 0.59q)/q

  ac = 1800/q +0.59

where ac=average cost; tc=total cost; fc=fixed cost; vc=variable cost; q=quantity sold

You can see that the average cost will go down as quantity increases, because it spreads the fixed cost over a larger number of cups.

Answer: m>−3

Step-by-step explanation:

Let's solve your inequality step-by-step.

−9<m−6

Step 1: Flip the equation.

m−6>−9

Step 2: Add 6 to both sides.

m−6+6>−9+6

m>−3

Answer:

i think it’s $3,792 because 11 • 10 = 110 and 12 • 4 = 48 so 110 + 48 = 158 and 158 • 24 = 3,792

Step-by-step explanation:

Answer:

3.50+0.75x = 15.50

0.75x = 12 divide both sides by 0.75 to get your answer

Answer:

x = 8

Step-by-step explanation:

4x + 3 = 35

subtract 3 from both sides

4x + 3 - 3 = 35 - 4

4x = 32

divide both sides by 4

4x / 4 = x

32/4 = 8

we're left with x = 8

Answer:

x = 8

Step-by-step explanation:

To solve for x you need to isolate it

First, subtract 3 from both sides, so you end up with:

4x = 32

Then, divide both sides by 4 to isolate the x

x = 8

Using the probability concept, it is found that there is a [tex]\frac{1}{4}[/tex] probability that a teenager selected at random is female and their favorite hobby is watching films.

A probability is given by the number of desired outcomes divided by the number of total outcomes.

fresh foods

Step-by-step explanation:

find a multiple such as 15  and caculate

3 x 5 = 15 |5 x 3= 15     for fresh foods its 4 per 5 so 15 - 3

and karmels is 3 for 2.50  thus 15 is 2.50 x 5 or 12.50

The exact slope is impossible to know for sure, because the function is not written out explicitly. (If we did, we could just do dV/dt evaluated at t = 10.)

However, you can estimate the slope at P by finding the average rate of change between t=5 and t=15, or by taking the average of the slopes of the adjacent secants. There are several ways to approximate the answer, but I don’t think you can find its exact value.

The solution is,  1 and 1/3 scoops would result in the correct amount of sugar.

Division is the process of splitting a number or an amount into equal parts.

Division is one of the four basic operations of arithmetic, the ways that numbers are combined to make new numbers. The other operations are addition, subtraction, and multiplication.

here, we have,

A baker needs `2/3` cup of sugar, but he can only find a `1/2` cup measure, so he decides to estimate.

so, we have,

2/3=(4/3) / 2

so he needs 4/3 scoops.

that is 1 and 1/3 scoops

The solution is,  1 and 1/3 scoops would result in the correct amount of sugar.
