1.  The type of angles that will be formed by the sides of a square are C. Right Angles.


2. An obtuse angle is an angle that measures greater than 90, but less than 180.

So the answer will be B. 100


3. An acute angle is an angle that measures less than 90 degrees.

So the answer will be D. 28

Write the inverse variation function given that y varies inversely with x, and y = 0.25 when x = 8.
storchak [24]

Answer:

Step-by-step explanation:

If a given variable varies inversely with another variable, an increase in the value of the given variable would cause a corresponding decrease in the value of the other variable. Also, a decrease in the value of the given variable would cause a corresponding increase in the value of the other variable.

If y varies inversely with x, we would introduce a cost of variation, k so that the expression becomes

y = k/x

When y = 0.25, x = 8

Substituting into the expression above, it becomes

0.25 = k/8

k = 0.25 × 8

k = 2

The inverse variation function is

y = 2/x

Solve the inequality and show your solution on a number line: 0.2x−2<7−8x
Allisa [31]

Answer:

x< \frac{45}{41}  or x< 1.098

The graph in the attached figure

Step-by-step explanation:

we have

0.2x-2 < 7-8x

Solve for x

Adds 2 both sides

0.2x-2+2 < 7-8x+2

0.2x < 9-8x

Adds 8x both sides

0.2x+8x < 9-8x+8x

8.2x < 9

Divide by 8.2 both sides

x < 9/8.2

Remember that

8.2=82/10

substitute

x < 9/(82/10)

x< \frac{90}{82}

Simplify

x< \frac{45}{41}  or x< 1.098

The solution is the interval ------> (-∞, 45/41)

All real numbers less than 45/41

In a number line , the solution is the shaded area at left of x=45/41 (open circle)
