The total cost would be $283.5

• The given length of a spool of ribbon = 6.75 meters
• The amount of spools a craft club buys = 21
• The given cost of a ribbon = $2

Further Explanation

To determine the total cost of the spools of ribbon bought, then the given length of a spool of ribbon (6.75) will be multiplied by the number of spools a craft clubs (21); the resulting value finally be multiplied by the given cost of a ribbon per meter (which is $2).

Thus,

= 6.75 x 21

= 141.75

Deriving the total amount it would cost the craft club:

= 141.75 x 2 (being the cost of a ribbon per meter)

= 283.5

Therefore, the total amount it would the craft club to buy 21 spools of ribbon is $283.5

The above mathematical expression is a practical example of a number problem, and it focus mainly on Multiplication. Multiplication is a basic mathematical operation and a function of BODMAS (an order of operations).

Multiplication has to do the repeated addition of two or more numerical value to derive a final value.

.07×1.22 = ?
first take away the decimals in the question, 7×122 =854.
now add the decimals back to the answer, we had 4 decimal places in the questions so add 4 decimal places to 854 = 0.0854

answer= 0.0854

1,200÷3=400_3×400=1,200.

3610 ÷ 33.5 = 107.761194 107.76 miles per hour

-(4+4/25)

= -(4+16/100)

=-(4.00 + 0.16)

= -4.16

0.2×0.8
first take away the decimals, but remember the number of decimal points you had hence, 2×8=16 , now put the decimals back into the answer, there were two decimal places in the question so, add 2 decimal places to 16, = 0.16

answer= 0.16

5+8=thirteen i mean 13

it is 0.16 I am sorry if it is wrong

10(x+20) - 12x = 100, 10x + 200 -12x = 100, -2x = -100, x+20 = 70 cents, x = 50 cents

Yes because if the ratio is 9:10, then the new ratio would be ?:30. Since 10 was multiplied by 3, 9 should also be multiplied by 3, which equals 27. 30+27=57 so yes it is a reasonable number for the total

Charles Lindbergh made the first solo airplane flight from New York to paris. His flight covered about 3 610 miles in 33.5 hours. Let’s find the Unit Rate for this given data: => 3 610 miles is the total distance => 33.5 hours is the time Let’s divide the distance by time to get the answer => 3 610 / 33.5 => 107.8 miles per hour – this is the unit rate that Charles travelled in plane from New York to Paris

Basically, the fractions are 2/5 vs. 3/8. As always, in order to compare fractions, you must first have a common denominator. The easiest way to achieve that is by multiplying the two denominators by each other. 5*8=40. You must also multiply the numerators by the same thing you multiplied the denominators by, so 3*5=15, and 2*8=16. The new fractions are 16/40 vs. 15/40. Therefore, Vet A has seen more dogs.

Answer:

Step-by-step explanation:

Just take the number of sevens and put that number as an exponent.

1 is closer to 0 because it's next to it

20 kg bag of bananas for 10 dollars This is the given situation in which in every 20 kilogram of bananas, the costs is 10 dollars. Now, let us calculate how much each kg of banana costs will. Let’s solve for the unit rate of this given data: => 20 kg bag of banana => 10 dollars = cost Now, let’s divide this to get the answer that we need. => 20 / 10 => 2 bananas per dollars = 2 banana/dollars Or 10 / 20 => 0.5 dollars/1kg of banana

The two factors to make 4800 is 60 and 80. I hope this helped! :)

1. We assume, that the number 96 is 100% - because it's the output value of the task. 
2. We assume, that x is the value we are looking for. 
3. If 96 is 100%, so we can write it down as 96=100%. 
4. We know, that x is 33% of the output value, so we can write it down as x=33%. 
5. Now we have two simple equations:
1) 96=100%
2) x=33%
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
96/x=100%/33%

13=5m-2

The way you write 10x10x10x10 using exponents. The way you use exponents is by counting the numbers of 10 there are since there is four you have to put 10 with a little number four on the top next to the number. Just in case that way you say it is 10 to the fourth power

Given situation: Jack crawled 3ft and Christine crawled ¾ the distance of jack crawled. Question: Find the total distance that Jack and Christine crawled. Solutions: => 3 feet => ¾ of Jack’s distance. Get the ¾ value of 3 feet. => ¾ = .75 => 3 * .75 = 2.25 The distance that Christine crawled is 2.25 Let’s add to get the total distance they crawled. => 3 + 2.25 => 5.25 total distance they crawled.

To rent 7 movies, he needs 2(7) + 12 = $26.
But he has only $10. So he needs more 26 - 10 = $16.

The three lengths are 3x, 6x, 8x.

The perimeter of a triangle is the sum of all lengths:
3x + 6x + 8x = 520.

Solving for x,
17x = 520
x = 30.59 cm

So the three lengths are
3(30.59) = 91.77 cm
6(30.59) = 183.54 cm
8(30.59) = 244.72 cm
