5. MERRY-GO-ROUND Mr. Lee is
putting trim around the edge of a
circular merry-go-round that has a
radius of 8 feet. How much trim
does he need to buy to the
nearest tenth?

50.30 ft

Step-by-step explanation: you have to multiply the radius by 2 to multiply it by 3.14 the answer is 50.24 but it's to the nearest tenth meaning you have to round it.

you'll have to round it up because if you round it down Mr. Lee won't hav enough trim

answer: option a.

step-by-step explanation:

you know that the quadrilateral opqr ( a four sided figure) is inscribed in circle. this means that all its vertices are on the circle.

then, by definition, the opposite angles of the quadrilateral are supplementary, this means that the sum of their measures is 180 degrees.

you can observe in the figure that the angles ∠opq   and the angle ∠orq   are opposite, therefore:

then, can be used to d to calculate the measure of ∠opq

b: |12 – x| ≤ 0.25

step-by-step explanation:      

let x be the possible lengths in inches, of the ribbons jaime cut.

we have been given that jaime is cutting strips of ribbon for a project. he tries to cut each piece to be 12 inches long, but sometimes he cuts it too long or too short by as much as 0.25 inch.  

we can represent this information in an inequality as:

by the definition of absolute value function we will get,

upon combining our inequalities we will get,

therefore, the inequality   describes all the possible lengths (x), in inches, of the ribbons jaime cut.
