Answer:
20 minutes( 0.3333 hours) after they leave the station will they be 50 km apart, if the Two trains on opposite tracks leave the same station at the same time. One train travels at an average speed of 80 km/hr and the other travels at an average speed of 70 km/hr.
Step-by-step explanation:
The given is,
One train travels at an average speed of 80 km/hr
The other travels at an average speed of 70 km/hr
Step:1
Formula to calculate the distance traveled by two trains,
Distance traveled by two trains = (Rate of speed of train one +
Rate of speed of other train) × Time
From the given the above equation becomes,
Let, h = Time taken to each the distance
50 = ( 80 + 70 ) h
50 = (150) h
= 0.3333 hours
= ( 0.333 × 60 ) ( ∵ 1 hr = 60 minutes )
h = 20 minutes
Step:2
Check for solution,
From equation (1),
50 = ( 80+70 ) (0.3333)
50 = (150)(0.3333)
50 = 50
Result:
20 minutes( 0.3333 hours) after they leave the station will they be 50 km apart.

Mr. Peralta had $300 in his savings account in March. He continued to add money to his savings account and by August, the value of the savings account had increased by 20%. How much money is in Mr. Peralta’s account in August?
Identify and label the point on the double number line that represents the original amount of money in Mr. Peralta's savings account.
Answer:
ima say $360.correct me if im wrong-^-
Step-by-step explanation:
The total amount of money in Mr. Peralta's savings account is $360.
What is the percentage?A percentage is a value per hundredth. Percentages can be converted into decimals and fractions by dividing the percentage value by a hundred.
Given, Mr. Peralta had $300 in his savings account in March.
By August, the value of the savings account had increased by 20%.
Let, 'x' be the total amount after an increase of 20%.
So, 120% of $300 is 'x'.
Therefore,
(120/100)×300 = x.
300×1.2 = x.
x = 360.
So, By august total money in his account is $360.

Answer:
4. 23
4. 206
5. 75 ft
7. 6 sections
8. 6 families
Step-by-step explanation:
4. 3x + 5 is the same thing as 3 x 6 + 5 so it equals to 23
4. x to the power of 3 - 10 is equal to 6 to the power of 3 - 10 so it equals to 206
5. Formula for area of triangle = 1/2 x base x height
So, it's 1/2 x 10 x 15 = 75
7. 3/4 ÷ 1/8 = 6 (Trick: When dividing fractions, make sure to flip the fraction for the 2nd one and leave the 1st one as the same. After that, multiply them together)
8. 3 families have 4-5 pets, 2 families have 6-7 pets and 1 family have 8-9 pets. At least 4 pets means 4 pets and above. So 3 + 2 + 1 = 6 families.
4. 3x + 5. Substitute the X for 6. The expression is (3 x 6) + 5= 23.
X³ - 10. Substitute the X for 6. 6³-10= 216.
5. I'm not 100% sure but I believe that it is 75. I might be wrong.
