Machine a produces 156 toys in 13 hours while machine b produces 90 toys in 7 hours. which rate is higher?

machine machine B produces more than machine A

Step-by-step explanation:

It takes machine A almost double the time of machine B to produce 156 toys

Say machine B is using same time as machine A, it will for sure produce about 180 toys

Hence machine B is faster

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.

the answer is:

the answer is:

to solve the problem, we need to remember the quotient of power property, it's defined by the following relation:

if we have a quotienf of powers that have the same base, we need to keep the same base and subtract the exponent of the denominator power to the exponent of the numerator power.

so, we are given the expression:

then, calculating we have:

hence, the answer is:

have a nice day!
