To go on the class trip, chang needs at least $125. he has saved $45, and he makes $7 an hour at his job. what is the minimum number of complete hours he must work to have enough money to go on the trip? (assume there are no withholdings from his check.)

12 hours

Step-by-step explanation:

If he has already saved $45, he needs $80 more.

80 divided by 7 = 11.4

He isn't able to work a fourth of an hour, so he will need to work a full 12 hours in order to get $125.

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'.

whats the question?
