We can use the formula length x width x height. Substitute in the numbers for words and you get:

14 x 14 x 19...

...which equals 3724cm^3.

Hope I helped! Sorry if I'm wrong.

ankoles [38]

Area of a circle is pi x r ^2

R = diameter/2

R = 1.8/2 = 0.9

Area = 3.142 x 0.9^2

Area = 2.5 square cm.

Write the prime factorization for 65,169

posledela

Let's try to find some primes that divide this number.

The number is not divisible by 2, because it is odd.

The number is divisible by 3 though, because the sum of its digits is:

$6+5+1+6+9=27=3\cdot 9$

So, we can divide the number by 3 and keep going with the factorization:

$65169\div 3 = 21723$

This number is again divisible by 3, because

$2+1+7+2+3 = 15 = 3\cdot 5$

We have

$21723\div 3 = 7241$

This number is no longer divisible by 3. Let's go on looking for primes that divide it: 5 doesn't because the number doesn't end in 0 nor 5. This number is not divisible by 7 or 11 either (just try). It is divisible by 13 though: we have

$7241\div 13 = 557$

And 557 is prime, so we're done. This means that the prime factorization of 65169 is

$3^2\cdot 13 \cdot 557$

Lu is making a quilt that is 20 squares wide and has 18 rows the border of the quilt is made by using each toy design equally as

mixer [17]

Answer:

The correct answer is two designs are used 12 times each and other four designs are used for 13 times each.

Step-by-step explanation:

Width of the quilt Lu is making is 18 rows of 20 squares each.

Thus the perimeter of the quilt is 20 + 20 + 18 + 18 = 76.

We can also say there are 76 square as the boundary which are to be bordered with toy designs.

Each square can hold 1 design of toy and there are 6 different designs of toys.

Thus number of times each design is used $\frac{76}{6}$ = 12 $\frac{4}{6}$ .

Thus there are two designs used 12 times each and other four designs are used for 13 times each.
