Answer:

4) A

5) E

Step-by-step explanation:

$\frac{x}{y}=\frac{1}{10} * \frac{z}{y}$

$\frac{x}{y} =\frac{1z}{10y}$

Cross multiply the equation and you get:

$10xy=zy$

Since $\frac{a}{b}=\frac{c}{d}$ is the same thing as $ad=bc$ , you can change the equation into $\frac{x}{z} =\frac{y}{10y}$

Cancel out the y on the top and bottom and you get 1/10

$\frac{2}{3} *\frac{x}{2} =5$ , simplify and you get $\frac{x}{3} =5$ so x=15

$\frac{1}{5} * 3(x)$ is equal to $\frac{1}{5} *3(15)$ after you plug in x, and that is equal to 9

A rectangular prism has a length of 20 in., a width of 2 in., and a height of 314 in.

Novay_Z [31]

First solve the volume of the prism
V = l x w x h
where l is the length
w is the width
h is the hieght

V = 20 x 2 x 314
V = 12560 cu in

then solve the volume of the cube
V = e^3
V = 14^3
V = 2774 cu in

number of cube = 12560 / 2774
number of cube = 4 cubes

Of the last 20 balloons sold at a party store, 5 were pink. Considering this data, how many of the next 12 balloons sold would y

marusya05 [52]

Answer: 3 balloons

Step-by-step explanation:

The ratio would be pink balloons to total balloons (aka pink/total), so 5 to 20 (aka 5/20). This simplifies to 1/4. If the new total is 12, and x represents pin balloons, then you can do 1/4=x/12. By cross multiplying, you get 12=4x. Divide both sides by 4 and x would equal 3. Therefore, the party store should expect to sell 3 pink balloons.

Given the midpoint and one endpoint of a line segment, find the other endpoint.

neonofarm [45]

Answer:

(-12 , 2)

Step-by-step explanation:

GIVEN :-

Co-ordinates of one endpoint = (-4 , -10)
Co-ordinates of the midpoint = (-8 , -4)

TO FIND :-

Co-ordinates of another endpoint.

FACTS TO KNOW BEFORE SOLVING :-

Section Formula :-

Let AB be a line segment where co-ordinates of A = (x¹ , y¹) and co-ordinates of B = (x² , y²). Let P be the midpoint of AB . So , by using section formula , the co-ordinates of P =

$(x , y) = (\frac{x^2 + x^1}{2} ,\frac{y^2 + y^1}{2} )$
