Two trapezoids below are similar what is the length of RS?

stepladder [879]

9514 1404 393

Answer:

11.5 m

Step-by-step explanation:

The fact that the figures are similar means the side lengths are proportional:

RS/QT = BC/AD

RS/(7 m) = (2.3 m)/(1.4 m)

RS = (7 m)(2.3/1.4) . . . . . . multiply by 7 m

RS = 11.5 m

Juanita runs every third day and swims every fifth day. If Juanita runs and swims today, in how many days will she run and swim

Ber [7]

we know that

The least
common multiple (LCM) of two or more numbers is the least

number, other than zero, that is a multiple of all the numbers.

In this problem, we are looking for the least common multiple of $3$ and $5$

Multiply $3$ by $5$

$LCM=3*5\\ LCM=15$

therefore

On the $15th$ day after today, she will do both on the same day

the answer is

$15 days$

T/2 + 3 = 5 (solve for t)

Mashutka [201]

Answer:

t = 4

Step-by-step explanation:

Given

$\frac{t}{2}$ + 3 = 5 ( subtract 3 from both sides )

$\frac{t}{2}$ = 2

Multiply both sides by 2 to clear the fraction

t = 2 × 2 = 4
