If y varies directly as x, and y is 18 when x is 5, which expression can be used to find the value of y when x is 11?

Rzqust [24]

Y=kx is the direct variation equation
First plug in the x, y values given to find K
18=k(5)
18/5=k
3.6 = k
Use the k and write a new equation.
y=3.6x
Plug in the x value to solve for y.
y = 3.6(11)
y= 39.6

Can some explain steps

Mashutka [201]

Answer:

r = 3.

Step-by-step explanation:

16 = 10 + √(3r + 27)

√(3r + 27) = 6

Square both sides:

3r + 27 = 36

3r = 36 - 27 = 9

r = 3.

Check the result:

Left side of the equation = 16

Right side = 10 + √(9 + 27)

= 10 + √36 = 16

Find the volume of a pyramid with a square base, where the perimeter of the

lianna [129]

Answer:

$42.7\,\,cubic\,\, meters$

Step-by-step explanation:

Given: Perimeter of base of a pyramid = 12.8 m

Height of the pyramid = 12.5 m

To find: volume of a pyramid

Solution:

Perimeter of base of a pyramid = 12.8 m

As base of the pyramid is a square,

12.8 = $4(side\,\,of\,\,a\,\,square)$

side of a square = $\frac{12.8}{4}=3.2\,\,m$

Area of a square (A) = $(side\,\,of\,\,a\,\,square)^2=(3.2)^2=10.24\,\,m^2$

Height of the pyramid (h) = 12.5 m

Volume of the pyramid = $\frac{Ah}{3}=\frac{1}{3}(10.24)(12.5)=42.7\,\,cubic \,\,meters$
