Mathematics
1 answer:
Dima020 [189]3 years ago
3 0

Answer:

∠1 = 120°

Step-by-step explanation:

Since the 2 lines are parallel

Angles 5x + 15 and 3x - 3 are same- side interior angles and are supplementary, thus

5x + 15 + 3x - 3 = 180, that is

8x + 12 = 180 ( subtract 12 from both sides )

8x = 168 ( divide both sides by 8 )

x = 21

Hence

∠1 = 5x + 15 ( corresponding angles )

    = (5 × 21) + 15 = 105 + 15 = 120°

Lemur [1.5K]

Answer: There are 52 men we can expect to have been involved in a minor traffic accident.

Step-by-step explanation:

Since we have given that

Percentage of men has been involved in a minor traffic accident = 13%

Number of men surveyed = 400

So, Number of sample men we can expect to have been involved in a minor traffic accident is given by

\dfrac{13}{100}\times 400\\\\=0.13\times 400\\\\=52

Hence, there are 52 men we can expect to have been involved in a minor traffic accident.

Natalle is a softball coach. She has a pitching private lesson with Kasey. Kasey's mom pays Natalle $11 per hour plus a $6 tip.
kirill [66]
11t\text{ + 6 = 39}

where t is the number of hours worked by Natalle

Here, we want to write an equation that will represent the given scenario

Let the number of hours for which she earned the pay be t

From the question, she earns $11 per hour

So for t hours, the amount earned excluding the tip will be;

(11\times t)\text{ = \$11t}

Now, let us add the tip and equate to the total amount earned

We have this as;

11t\text{ + 6 = 39}
