Answer:

c. 135 hr

Step-by-step explanation:

The following method of converting units is called "dimensional analysis."

Write every conversion factor as a fraction. Each conversion factor fraction equals 1, so it changes units but not the value. In the end, all the undesired units cancel out leaving the desired units. Multiply the given amount by the necessary conversion factors until you arrive at the desired units.

$3~extra~bagal \times \dfrac{10~sobrang~bagal}{1~extra~bagal} \times \dfrac{3~bagal}{1~sobrang~bagal} \times \dfrac{90~min}{1~bagal} \times \dfrac{1~hr}{60~min} =$

$= 135~hr}$

Answer:

the distance is 9.1 inches (please give brainliest)

Step-by-step explanation:

we must use the pythagorean theorem:

5.7^2 + 7.1^2 = c^2

(c being the distance being the two corners)

c^2 = 82.9

c = sqrt(82.9) ≈ 9.1

<h2>Answer</h2>

After the dilation $\frac{5}{3}$ around the center of dilation (2, -2), our triangle will have coordinates:

$R'=(2,3)$

$S'=(2,-2)$

$T'=(-3,-2)$

<h2>Explanation</h2>

First, we are going to translate the center of dilation to the origin. Since the center of dilation is (2, -2) we need to move two units to the left (-2) and two units up (2) to get to the origin. Therefore, our first partial rule will be:

$(x,y)$ → $(x-2, y+2)$

Next, we are going to perform our dilation, so we are going to multiply our resulting point by the dilation factor $\frac{5}{3}$ . Therefore our second partial rule will be:

$(x,y)$ → $\frac{5}{3} (x-2,y+2)$

$(x,y)$ → $(\frac{5}{3} x-\frac{10}{3} ,\frac{5}{3} y+\frac{10}{3} )$

Now, the only thing left to create our actual rule is going back from the origin to the original center of dilation, so we need to move two units to the right (2) and two units down (-2)

$(x,y)$ → $(\frac{5}{3} x-\frac{10}{3}+2,\frac{5}{3} y+\frac{10}{3}-2)$
