Using the formula z=Kx/y If z = 6 when x = 3 and y = 4, then what is z when x = 5 and y = 2?

Veseljchak [2.6K]

Answer:

z=kx/y

zy=kx

zy/x=kx/x ( divided both side by x. to find k)

k=zy/x

k=6×4/3(z=6,y=4,x=3)

k=24/3

k=8

so z=kx/y

z=8×5/2(replace the numbers in the place of variables,k=8,x=5,y=2)

z=40/2

z=20

In ΔDEF, the measure of ∠F=90°, EF = 2.3 feet, and FD = 2.9 feet. Find the measure of ∠D to the nearest tenth of a degree.

Phoenix [80]

Answer:

$\theta=38.42 \textdegree$

Step-by-step explanation:

From the question we are told that:

Angle of F $\angle F=90 \textdegree$

Length of $EF = 2.3 feet,$

Length of $FD= 2.9 feet,$

Generally the equation for Angle D $\theta$ is mathematically given by

Since $\angle F=90$ .The triangle is a right angle Triangle

Therefore

$tan \theta=\frac{EF}{FD}$

$tan \theta=\frac{2.3}{2.9}$

$\theta=tan^{-1} 0.793$

$\theta=38.42 \textdegree$

a pet store sells only dogs and cats. The ratio of dogs to cats at the pet store was 6:5. If there are 154 pets at the pet store

Y_Kistochka [10]

Step-by-step explanation:

assume the number of dogs and cats to be 6x and 5x

dogs + cats = 11x

we are given that 11x= 154

hence x=11

dogs = 6x = 6×11 = 66
