F) Tyler’s gray paint is a darker shade of gray than Hillary’s gray paint

When we take Tyler’s amount, we should do 8/30, which equals approximately .27. When we do the same thing with Hillary’s amount (10/40), we get .25. .27>.25, meaning that for the amount of white paint there is, more black paint is going into Tyler’s. As we know, black makes paint dark, so Tyler’s would be darker.

Polyhedron P is a cube with a corner removed and relocated to the top of P. Polyhedron Q is a cube. How do their surface areas c

tatiyna

Answer:

C. P’s surface area is greater than Q’s surface area.

Step-by-step explanation:

Refer to attached

With a corner removed, it doesn't change surface area of the cube as same area is exposed equal to the area of 3 small faces.

With the corner relocated to the top of the cube, it covers the area of one small face but adds up small 5 faces (4 sides and one top). In total the P has more surface area than the Q.

Correct answer choice is C.

Diameter=d=8in

.We know

$\\ \sf\longmapsto Area=\dfrac{πd^2}{4}$

$\\ \sf\longmapsto Area=\dfrac{3.14(8)^2}{4}$

$\\ \sf\longmapsto Area=\dfrac{3.14(64)}{4}$

$\\ \sf\longmapsto Area=3.14(16)$

$\\ \sf\longmapsto Area=50.24m^2$

Ralph is 3 times as old as Sara. In 6 years, Ralph will be only twice as old as Sara will be then.

R = 3S

R + 6 = 2 (S+6)

Substitute the first equation in the second one:

(3S) + 6 = 2 (S + 6)

3S + 6 = 2S + 12

S + 6 = 12

R = 18
S = 6

Check:

R is 3 times S now.

In 6 years, R will be (18 + 6) = 24, S will be (6 + 6) = 12.

24 = 2 x 12 yay
