Given the equation p = s Subscript 1 Baseline t minus 2 Subscript 2 Baseline t, which equation is solved for t? t = p (s Subscri

gulaghasi [49]

Answer:

Option C) is correct

That is t=StartFraction p Over s Subscript 1 Baseline minus s Subscript 2 Baseline EndFraction

It also can be written as $t=\frac{p}{s_{1}-s_{2}}$

Step-by-step explanation:

Given equation can be written as below:

$p=s_{1}t-s_{2}t$

Now to solve the equation for t:

$p=s_{1}t-s_{2}t$

Taking common term t outside on RHS we get

$p=(s_{1}-s_{2})t$

$\frac{p}{s_{1}-s_{2}}=t$

Rewritting the above equation as below

$t=\frac{p}{s_{1}-s_{2}}$

Therefore option C) is correct

That is t=StartFraction p Over s Subscript 1 Baseline minus s Subscript 2 Baseline EndFraction

It also can be written as $t=\frac{p}{s_{1}-s_{2}}$

Problem 5. A skating rink in the shape shown has an area of

nexus9112 [7]

Answer:

$P=\dfrac{\pi r^2+2800}{r} $ ft$

Step-by-step explanation:

Let the length of the rectangular part =l

The width will be equal to the diameter of the semicircles.

Area of the Skating Rink= $2(\frac{\pi r^2}{2})+(lX2r)$

Therefore:

$\pi r^2+2lr=2800\\2lr=2800-\pi r^2\\$Divide both sides by 2r\\l=\dfrac{2800-\pi r^2}{2r}$

Perimeter of the Shape =Perimeter of two Semicircles + 2l

$=2\pi r+2\left(\dfrac{2800-\pi r^2}{2r}\right)\\=2\pi r+\dfrac{2800-\pi r^2}{r}\\=\dfrac{2\pi r^2+2800-\pi r^2}{r}\\=\dfrac{\pi r^2+2800}{r}$

The perimeter of the rink is given as:

$P=\dfrac{\pi r^2+2800}{r} $ ft$

tatiyna

Height over shadow
H/S

9 in is 9/12=.75
So
Boys height /shadow. Flags height /shadow

4.75/6= X/19

Cross multiply
