Officer Brimberry wrote 8 tickets for traffic violations last week, but only 1 ticket this week. What is the percent decrease? Give your answer to the nearest tenth of a percent.

Answers

Answer:

87.5%

Step-by-step explanation:

Given:

Number of tickets written in the last week, $T_(1)=8$

Number of tickets written in this month, $T_(2) =1$

Difference in tickets written = $T_(2)-T_(1)=8-1=7$

∴ Percent decrease = $(T_(2)-T_(1))/(T_(1))* 100=(7)/(8)* 100=87.5$

Therefore, percent decrease in tickets written is 87.5 %.

Divide £300 in a ratio of 3:7

Answers

Ratio is:
$3:7$
it means you have to sum
$3+7=10$
Now you have to divide $300$ by $10$
$300/10=30$
Now multiplay
$3*30=90$
and
$7*30=210$
so £ $300$ in ratio $3:7$ will be $90:210$

1. Add 3 + 7 = 10

2. Divide 300 by 10 = 30

3. Times 30 x 3 = 90

4. Times 30 x 7 = 210

90 + 210 = 300

your answer is 90 : 210

If 5 times a number is increased by 4 the result is at least 19.

Answers

Actually if you multiply 5x1 then you get 5 then if you increase it by 4 you would only get 9. But thats just an example.

5x+4 $\geq$ 19

x would be the number that you are looking for. Since the question says that is is AT LEAST 19, you can make the equation greater than or equal to.

a dime is flipped and a six-sided die is rolled what is the probability of flipping heads and rolling an odd number

Answers

so rolling an odd number is 1/2 since there is 3/6 odd numbers on a dice. A coin has two sides, so heads would also have a 1/2 chance. Multiply across, 1/2*1/2 = 1/4 there is a 1/4 possibility. MARK ME BRAINLIEST PLEASE

assuming both are happening at once the probability is 1/4
