I cannot figure this question out
uysha [10]

Answer:

1/12

Step-by-step explanation:

you need to make sure that they have a common denominator before doing anything.

Find the lowest common multiple (lcm), which would be 12 (3 x 4 = 12)

So then, put 12 as both denominators, and subtract.

7/12 - 9/12 is equal to 28/12 - 27/12, because 3 miltiplied by 4 equals 12, therefore you mutiply the 7 by the 4, and 4 miltiplied by 3 equals 12, therefore you multiply the 9 by the 3.


Sorry if this is confusing, i tried explaining as best i could! Hope this helped!

Suppose y varies jointly as x & z. If y = -180 when z = 15and x = -3,then find y when x = 7 and z = -5. 1 point
sweet [91]

Answer:

y = - 140

Step-by-step explanation:

The statement

y varies jointly as x & z is written as

<h3>y = kxz </h3>

to find y when x = 7 and z = -5 we must first find the relationship between the variables

when y = - 180

z = 15

x = - 3

- 180 = k(15)(-3)

-180 = - 45k

Divide both sides by - 45

k = 4

The formula for the variation is

<h2>y = 4xz</h2>

when

x = 7

z = -5

y = 4(7)(-5)

y = 4(-35)

<h3>y = - 140</h3>

Hope this helps you

The perimeter is 54 m. The apothem is \root(3)(3) . To the nearest tenth, what is the area of this regular polygon?
Serjik [45]

The area of this regular polygon is 46.8 square units

<h3>How to determine the area of this regular polygon?</h3>

The given parameters are:

Perimeter, p = 54 m

Apothem, a = √3

The area of this regular polygon is then calculated as:

Area = 0.5 * Apothem * Perimeter

Substitute the known values in the above equation

Area = 0.5 * √3 *  54

Evaluate the product

Area = 46.8

Hence, the area of this regular polygon is 46.8 square units
