Answer:

Alright, for question 7, the angle pair relationship is that they are corresponding angles.

So, 17x - 34 = 13x - 14. This means that 4x = 20, and x = 5 :)

For question 8, the angles are a linear pair. They are supplementary (adding to 180) :)

So, 37x - 17 + 33x - 13 = 180

This means taht 4x = 210, and x = 52.5? (I'm not sure if I screwed up on the arithmetic on this one, please correct if you find any mistakes!)

Cant find the answer
dedylja [7]

Answer:

Carter family = 25 hours

Davis family = 31 hours

Step-by-step explanation:

Let's say the number of hours the Carter family used their sprinkler is x and the number of hours the Davis family used their sprinkler for is y.

So combined:

x + y = 45 hours

and we are also told that:

40x + 15y = 1300 L

So we can do simultaneous equations to solve the problem.

With some rearranging, we can figure out that:

y= 45 - x

and by substituting that into the second equation:

40x + 15 (45 -x) = 40x + 675 - 15x = 1300L

25x = 1300 - 675

25x = 625

x = 25 = hours that the Carter family used their sprinkler

and we can substitute that back into the original equation to find how many hours the Davis family used their sprinkler so:

25 + y = 56

y = 31

The Davis family used their sprinkler for 31 hours whilst the Carter family used their sprinkler for 25 hours.

The third term of an arithmetic sequence is 21, and the eighth term is 56. The first term is _____.
aleksley [76]
The first term is 7. This is because the sequence has a pattern of increasing by 7. If the first term was 7, the second would be 14, the third would be 21. The 4th would be 28, continue to the 8th term 56.

The probability that Fred's bus is late on any day is 0.09.
miv72 [106K]

Answer:

The bus would be 36 times late in 400 times of when Fred takes the bus

Step-by-step explanation:

Given that the probability of being the bus late is 0.09.

In order to find the number of times the bus will be late will be calculated by multiplying the total number of observations by probability.

It is also given that the total number of days he waits for bus is 400 times.

So,

The bus will be:

= 0.09*400\\=36

Hence,

The bus would be 36 times late in 400 times of when Fred takes the bus
