In the question, you are given that the two rectangles are similar. Rectangle A has a length of 15 feet and a width of 12 feet. While Rectangle B has a length of 60 feet and you are supposed to find the width of Rectangle B. With the labels of the measurement (length and width), you can find that the ratio on rectangle A to rectangle B is 15 : 60 or 1 : 4. With this knowledge, you can use the same ratio to find the width. 1 would represent 12 feet and 4 would represent 4 times 12. Hence the answer, 48.

In the problem it says triangle B, but it really meant to say rectangle B A reciprocal is also sometimes called a multiplicative inverse. The reciprocal is one of a pair of numbers that when multiplied together equals 1. Being able to reduce a number to a fraction makes it easier to find the reciprocal. Simply transposing the numerator and the denominator in a reciprocal fraction will allow you to find the reciprocal.

If you want to find the reciprocal of a whole number the best method would be to turn the number into a fraction in which the original number is the denominator and the numerator is 1. If you encounters a situation where you need to find the reciprocal of a decimal number you will then need to divide 1 by that number. #### ochoa

On the actual quiz, it says 3 squared and not 32. Just a heads up beacuse the answer to the qiuz answer is 5 but this answer is 10 #### Wyatt Williams

Among all the combinations, 12 = (r + c)4.5 can be used to represent the information in this case. To figure this out, one must have knowledge of basic algebra in mathematics and the word problems that are associated with it. Algebra is an important domain of mathematics and it is used in a variety of scientific fields for research purposes and for application purposes such as in engineering.

Indeed, algebra is considered as one of the most profound inventions in mathematics back on time. Ever since then, it has been research upon, developed, and have grown a lot to incorporate modern mathematical concepts. #### dinkinsk

In the equation, you can see that 250 marbles are split between blue marbles and red marbles. The equation states that there are 24 more blue marbles than red marbles. So let x = the number of red marbles. Which means that x + x + 24 = 250 marbles.We can simplify this to 2x + 24 = 250. Subtract 24 from each side to get 2x = 226. Then divide by 2 on each side to get that there are 113 red marbles. The question asked for the number of blue marbles, so you add 24 to 113 to get 137 blue marbles. To check, you can add 137 + 113 and you will get 250.
