Write the following as a ratio: 304 calories burned in 56 minutes

IgorC [24]

Answer:

The required ratio is 38 : 7

Step-by-step explanation:

Given,

304 calories burned in 56 minutes,

That is, the number of calories burnt in 56 minutes = 304

So, the ratio of the calories burnt and time in minutes = $\frac{304}{56}$

∵ HCF(304, 56) = 8,

Thus, the ratio of price of photos and number of photos = $\frac{304\div 8}{56\div 8}$

= $\frac{38}{7}$

If 10^x equals 0.1 percent of 10^y, where x and y are integers, which of the following must be true?

andrew-mc [135]

$10^x=0.1 \% \times 10^y \\ \\
10^x=\frac{0.1}{100} \times 10^y \\ \\
10^x=\frac{1}{1000} \times 10^y \\ \\
10^x=\frac{10^y}{10^3} \\ \\
10^x=10^{y-3} \\ \\
\log_{10} 10^x=\log_{10} 10^{y-3} \\ \\
x=y-3 \\ \\
y=x+3$

The answer is B.
