What value of z will make △DEF ≅ △JKI

Mathematics

Leto [7]3 years ago
6 0

Answer:

z = 11

Explanation:

5y + 13 = 6y

Subtract 5y by both sides.

13 = y

Next,

z + 22 = 3z

Subtract z by both sides.

22 = 2z

Then, divide both sides by 2.

11 = z

Finally plug those answers into the equations.

5(13) + 13 = 78

6(13) = 78

(11) + 22 = 33

3(11) = 33

So △DEF ≅ △JKI because the value of z = 11.

Maksim231197 [3]

Answer:

The Sureset Concrete Company

The tons of gravel and sand that should be purchased each day are:

Sand = 800 tons

Gravel = 700 tons

Step-by-step explanation:

Two ingredients for producing concrete = sand and gravel

Cost of sand per ton = $6

Cost of gravel per ton = $8

Sand and gravel = 75% of the concrete

Therefore 25% (100 - 75%) will be made up of cement and water

Tons of concrete produced each day = 2,000

Sand and gravel = 1,500 (2,000 * 75%)

Sand <= 40% of 2,000 = 800 tons

Gravel => 30% of 2,000 = 700 (1,500 - 800) tons

To minimize costs,  800 tons of gravel and 700 tons of sand should be purchased each day.

Total cost incurred daily for both sand and gravel = $10,400 (800 * $6 + 700 * $8)

fgiga [73]
Part A:

Given that a<span> bag contains 10 white golf balls and 6 striped golf balls, the ratio of white to striped golf balls is 10 : 6 = 5 : 3.

Given that </span>a<span> golfer wants to add 122 golf balls to the bag, the of balls each he should add is given by:

5\left( \frac{122}{5+3} \right) \ : \ 3\left( \frac{122}{5+3} \right)=5\left( \frac{122}{8} \right) \ : \ 3\left( \frac{122}{8} \right) \\  \\ =5(15.25) \ : \ 3(15.25)=76.25 \ : \ 45.75 \\  \\ \approx76:46

Therefore, the golfer shold add 76 white golf balls and 46 striped golf balls.



Part B.

You did not indicate the scale factor.

Assuming the scale factor is given by D(o, k) where k can be any number, then the cordinate of the </span><span>coordinates of the image of the quadrilateral VWXY are given by:

V'(6k, 2k), W(-2k, 4k), X(-3k, -2k), Y(3k,-5k)

That is you multiply the scale factor to the coordinates of the preimage to get the coordinates of the image.
