The ratio of the lengths of the corresponding sides of triangle ABC to triangle DEF is 2:3, and since side AC is the corresponding side of side DF -> Side DF = 3/2 side AC

Laurence, the stadium manager, spends $22,000 on a broadcast TV ad, $30,000 on a cable TV ad, and $6,000 on a radio ad. What per
Vesnalui [34]

38 % of amount is spent on broadcast TV advertising

<em><u>Solution:</u></em>

Given that,

Amount spend on broadcast TV ad = $ 22, 000

Amount spend on cable TV ad = $ 30, 000

Amount spend on radio ad = $ 6000

To find: percentage of broadcast TV advertising

Total amount = $ 22, 000 + $ 30, 000 + $ 6000

Total amount = $ 58000

percentage of broadcast TV advertising = \frac{\text{ amount spend on broadcast tv}}{\text{ total amount}} \times 100

\rightarrow \frac{22000}{58000} \times 100\\\\\rightarrow 0.3793 \times 100 = 37.93 \approx 38

Thus 38 % of amount is spent on broadcast TV advertising

Break apart the addends to find the sum 18+21
ololo11 [35]
We break apart the first numer:

10+8

the second:

20+1

and add like this:

18+21=10+8    +  20+1

now, we can mix up the order:

18+21=10+8    +  20+1= 10+20     + 8+1

add the parts:

18+21=10+8    +  20+1= 10+20     + 8+1=30+9=39
