Hi, can you please help me answer this direct proportion question?

Oksanka [162]

Answer:

X = 100

Step-by-step explanation:

In proportion questions, they want you to multiply one of the sides by a variable, (i usually represent it with K) and then change the proportion sign to an equal.
This is because proportional means they have a ratio between them, with one side increasing by "k" for each increase in the other side.

Multiply the left by k, so $y = \frac{k}{\sqrt{x} }$
we know that y= 5, for x = 36, so sub this in the equation
$5 = \frac{k}{\sqrt{36} }$
simplify $5 = \frac{k}{6 }$
re-arrange for k, <u>k = 5*6 = 30</u>
now we know k, we can create the real equation, $y = \frac{30}{\sqrt{x} }$
sub in 3 as y
$3 = \frac{30}{\sqrt{x} }$
<u>x = 100</u>

If one angle is x and the other angle.is 4x-15 what is the value of x

Bas_tet [7]

These two quantities obviously refer to a picture or drawing that shows how they're related to each other. Without the picture, they're not related, and there's no answer.

Three friends each have some ribbon,carol has 42 inches of ribbon, Tina has 2.5 feet of ribbon, Baxter has 1.5 yards of ribbon.

Doss [256]

Answer:

126 inches

Step-by-step explanation:

To express the total length of ribbon convert the three lengths into the same measurement of inches.

Carol has 42 inches.

Tina has 2.5 feet which is equal to 24+6=30 inches.

Baxter has 1.5 yards which is equal to 36+18 =54 inches.

This means in total there is 42 + 30 + 54= 126 inches
