Question 3 (1 point) 4 Marissa bought a used cell phone from her brother. She gave him a down payment of $15.50 to receive the phone. She will pay hin $7.50 each week until the cell phone is paid for in full. Which equation represents the relationship between w, the number of weekly payments Marissa has made, and t, the total amount that Marissa has paid to her brother? F (= 7.5w - 15.5 Ht= 15.5w + 7.5 Gt = 15.5w - 7.5 J = 7.5W + 15.5 оа F ob ос Od H​

v: l•w•h÷2.

v: 20•6•8 ÷2

v: 960÷2

v: 480

sum= when you add is how much the whole amount is

distance= when you use angles and it means how far it goes

step-by-step explanation:

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.

example 2 – simplify: step 1: completely factor both the numerators and denominators of all fractions. step 2: change the division sign to a multiplication sign and flip (or reciprocate) the fraction after the division sign; essential you need to multiply by the reciprocal. step 3 : cancel or reduce the fractions.
