Answer:

10

Step-by-step explanation:

I think is 10 because they are different triangles but both with the same measure, as you can see both angles are the same [36] and both sides of the triangle too [6] so when you divide the base [20] by 2 , 20÷2=10

Matt paid $450 in interest on a 15 month note for<br> $5600. Find the rate of interest paid.
Olin [163]

Answer:

The rate is 6.43%

Step-by-step explanation:

Given

I = 450 --Interest

P = 5600 -- Principal

T= 15\ months --Time

Required

Determine the rate

Using simple interest formula:

I = PRT

Make R the subject

R = \frac{I}{PT}

Convert time to years

T= 15\ months

T =\frac{15}{12}\ years

T =1.25\ years

Substitute values for I, P and T

R = \frac{450}{5600*1.25}

R = \frac{450}{7000}

R = 0.0643

Convert to percentage

R = 0.0643*100\%

R = 6.43\%

Steve travels 2 times as fast as Jill. Traveling in opposite directions, they are 120 miles apart after 2.5 hours. Find their ra
Tcecarenko [31]

let's recall that d = rt, distance = rate * time.

we know that Steve is twice as fast as Jill, so say if Jill has a speed or rate of "r", then Steve is traveling at 2r fast, now we know they both in opposite directions have covered a total of 120 miles, so if Jill covered "d" miles then Steve covered 120 -d, check the picture below.

\begin{array}{lcccl} &\stackrel{miles}{distance}&\stackrel{mph}{rate}&\stackrel{hours}{time}\\ \cline{2-4}&\\ Jill&d&r&2.5\\ Steve&120-d&2r&2.5 \end{array}~\hfill \begin{cases} d=2.5r\\[2em] 120-d=5r \end{cases} \\\\\\ \stackrel{\textit{substituting on the 2nd equation}}{120-2.5r=5r\implies 120=7.5r}\implies \cfrac{120}{7.5}=r\implies \stackrel{Jill's}{16=r}~\hfill \stackrel{Steve's}{32}
