3. Given that ∆RSV - ∆RTU, find the coordinates of S and the scale factor. R(0, 0) T(16,0) V(0, --6) U(0, -8)

MArishka [77]

Answer:

I'll give the scale factor and you can compute the coordinates of S

Step-by-step explanation:

the dilation if centered about the origin is the scale factor multiplied by each coordinate.

so looking at points V and U, the scale factor F is found by solving for F:

-6xF= -8

F=8/6=4/3

Now you can compute the coordinates for S

Evaluate.<br> 1/2 (11)(15 + 17) =

Andrei [34K]

Answer: 176

Step-by-step explanation:

To evaluate the equation we have to remove the parentheses and add 15 + 17...

1/2 (11)(15 + 17) =

= 11 * 32 * 1/2

Now, we have to turn it into a fraction and multiply it...

$\frac{1*11*32 }{2}$

= $\frac{352}{2}$

352 ÷ 2 = 176

I hope this helps!

sports warehouse had a sale on two models of baseball gloves. Model A sold for $30.00, and model B sold for $45.25. A total of 5

alexandr402 [8]

Answer:

18 model A gloves and 34 model B gloves

Step-by-step explanation:

Set up 2 equations based on the given information

Let 'x' represent the number of Model A gloves sold

Let 'y' represent the number of Model B gloves sold

Then..

$30x + $45.25y = $2,078.50 represents the total sold in dollars

x + y = 52 represents the total number of gloves sold

Solve the second equation for either variable...

x = 52 - y

Now plug this into the first equation...

$30(52 - y) + $45.25y = $2,078.50 {x became 52 - y}

Now solve for y...

$1,560 - $30y + $45.25y = $2,078.50

$15.25y = $518.50 (combine y terms, subtract $1,560 from both sides)

y = 34 (divide both sided by $15.25, dollar signs cancel out)
