Ivanna is saving money to buy a game. so far she has saved $20, which is four-fifths of the total cost of the game. how much does the game cost?

The games cost $25

Step-by-step explanation:

Hi, to answer this question we have to write an equation:

The price of the game (x) multiplied by four-fifths (4/5) must be equal to the money saved by Ivanna (20)

Mathematically speaking:

4/5 x =20

Solving for x

x = 20 / (4/5)

x = 25

The games cost $25

b. an equilateral triangle inscribed in a circle

step-by-step explanation:

we are given the figure of two circles having a triangle inside.

now, we know that,

"when a figure is lying inside an another figure, then the outside figure is known as circumscribed figure and the figure lying inside is referred to as the inscribed figure".

as we see that, the circles are containing the triangle completely.

thus, the circles are the circumscribed figures and the triangle is the inscribed figure.

hence, we get, 'an equilateral triangle is inscribed in a circle'.

d. millimeters per hour.

step-by-step explanation:

we are given that,

carlo used a rain gauge to measure the amount of water his lawn is receiving from the sprinklers.

since, according to the options, we see that,

water cannot be measured by 'miles per hour', 'meters per second' and 'grams per seconds'.

we get that, the water can be measured by 'millimeters per hour'.

hence, the appropriate rate for describing the amount of water is 'millimeters per hour'.
