Answer:

6

Step-by-step explanation:

We are doing unit rate.

Unit rate is when you get the value for 1 of the variables. In this, we would want to get the value for t. We do\frac{20}{4}=5 to find the t value. Now we do \frac{30}{5}=6 to find the value of the missing t. T=6.

Hope it Helps!

Answer:

t is 6 I believe

Step-by-step explanation:

t=4 s=20

20/2=4/2 divide both sides by 2 to simplify it

Then you get t=2 & s=10

then multiply 10 by 3 to get 30, and you do this to both sides so 2*3= 6

so when s is 30, t is 6

Norma-Jean [14]

Answer:

5 ft

Step-by-step explanation:

When we draw out our triangle, we should see that we have a right triangle and we need to solve for a leg:

Pythagorean Theorem: a² + b² = c²

12² + b² = 13²

144 + b² = 169

b² = 25

b = 5

I read 1/3 of a book in an hour.<br> How much more of the book will I read in 2 1/5 hours
Verizon [17]

Answer:

Step-by-step explanation:

To find the number of pages of the book in the given hour:

To find the number of pages in 2 1/5 hours, multiply the number of pages read in 1 hour by 2 1/5 hours.

\sf \text{  Number of pages read in 2 $\dfrac{1}{5}$ hours = $\dfrac{1}{3}*2\dfrac{1}{5}$ }

                                                       \sf = \dfrac{1}{3}*\dfrac{11}{5}\\\\=\dfrac{11}{15}

\sf \text{Number of pages read more in 2 $\dfrac{1}{5}$ hours = $\dfrac{11}{15}-\dfrac{1}{3}$}

                                                                 \sf =\dfrac{11}{15}-\dfrac{1*5}{3*5}\\\\=\dfrac{11}{15}-\dfrac{5}{15}\\\\=\dfrac{6}{15}
