Answer:

The height is 36 in

Step-by-step explanation:

This problem bothers on the mensuration of solid shapes, a rectangular based pyramid.

Step one

Given data

Volume v =  1944 in

length of base l =  18 in

width of base w = 9 in

Height h=   ?

Step two

we know that the expression for the volume of a pyramid is given as

volume=\frac{ lwh}{3}

substituting our given data we have

volume = \frac{18*9*h}{3} \\volume = \frac{162h}{3} \\volume= 54h

but volume = 1944 in therefore

1944= 54h\\h= \frac{1944}{54} \\h= 36 in

last year the cost of a season ticket for a rugby club £370. This year the cost of a season ticket for the club has been increas
Elden [556K]

Answer:

\frac{80}{370} OR \frac{8}{37}

Step-by-step explanation:

So first you find the difference between the new cost and the old cost:

450 - 370  = 80

So the increase was 80.

When you write it as a fraction you write the increase ( 80 ) over the starting cost ( 370 ).

Thus the answer becomes \frac{80}{370}

But you can always reduce it to its lowest terms thus:

\frac{8}{37}

storchak [24]
150 + 15x = 400
(-150) 150 + 15x = 400 (-150)
15x = 250
(/15) 15x = 250 (/15)
x = 16.67
So Chia can invite 16 people

Find the measure of XCY. PLEASE HELP ME AND SHOW WORK
Dovator [93]

Answer:

Measure of angle XCY is 60°.

Step-by-step explanation:

"Measure of all inscribed angles by the same arc in one segment of the circle are equal"

Using this property in the given circle,

m∠XWY = m∠XCY

60x = 61x - 1

61x - 60x = 1

x = 1

By substituting the value of 'x' in the measure of ∠XCY,

m∠XCY = 61x - 1

             = 61(1) - 1

             = 61 - 1

             = 60°

Therefore, measure of angle XCY is 60°.
