Answer:

y = -28 ÷ x

Step-by-step explanation:

The standard format of a inversely proportional equation goes by the format of y = k ÷ x. The question asks us to write an equation if y = 7 when x = -4 and y varies inversely with x.

So we substitute the values y = 7 and x = -4 in the equation y = k ÷ x

K = constant, we have to work this out

7 = k ÷ -4

7 × - 4 = k

k = - 4 × 7

k = -28

k = -28 So then we put this back into the original y = k ÷ x to find our final equation which is y = -28 ÷ x

Find the surface area to the nearest tenth
zlopas [31]

Answer: A. 184.8ft2

Step-by-step explanation:

The pyramid is made up of four sides that are rectangular, each side has a height of 12.4ft and base length of 6ft.

The base area is a square of 6ft by 6ft.

For the sides, area of a triangle is 1/2 x base x height

= 1/2 x 6 x 12.4 = 37.2m2

For the four triangles = 4 x 37.2 = 148.8m2

For the square base, area is 6 x 6 = 36m2

Total surface area = 148.8 + 36 = 184.8ft2

gogolik [260]

There are 100 students. In the 100 students, 79 of them have honors. To find the decimal form for the students who have honors, divide the total amount of students with honors with the total amount of students.

\frac{Honors}{Total} = \frac{79}{100}

Divide 79 by 100

79 \div 100 = 0.79

Your answer is 0.79
