XZ=15 and the perimeter of XWZ is 50. what is the length of WZ?

Mathematics
1 answer:
stiv31 [10]3 years ago
7 0

Assuming that this is an Isosceles Triangle which has 2 sides equal, then we can assume as well that XZ being the base of 15 and the total perimeter is XWZ = 50.

Perimeter = X + W + Z

Therefore;

XWZ (50) – XZ (15) = 35

Since we are assuming that this is an Isosceles triangle then 2 sides should have equal distance.

35 / 2 = 17.5

Hence, XW = 17.5 and ZW = 17.5

Perimeter = 15 + 17.5 + 17.5 = 50

Which is more 45g or 45ml?
MatroZZZ [7]

For water 1 gram = 1 ml.

This means 45 grams are equal to 45 ml's.

Neither one is greater than the other one as they are equal.

The problem doesn't state what is being measured, so the answer could be different depending on the density of the product being measured.

Please help me by marking the correct answer to each part of number 9. I really dont get this at all, so please tell me why your
natta225 [31]
A. False
Why? Because you cut off the triangle. The measurements are 20 mm and 10 mm.
B. True
Why? Because 20*10 = 200
C. False
Why? Because the base is 6 since 26 - 20 is 6. The height is 4, not 6 because 10 - 6 is 4.
D. True
Why? Because like question C., the base is 6, and the height is 4. 6*4 is 24/2 = 12. If you don't get this, the formula for all triangles is b*h*1/2
E. True
Why? Because from questions B. and D., the area of the rectangle is 200 and the area of the triangle is 12. 200 + 12 = 210.

Hope this helped,
