LaTanya leaves her house at 12:30 P.M. and bikes at /12 miles per h to Marta’s house. She stays at Marta’s house for 90 min. Both girls walk back to LaTanya’s house along the same route at ./.2.5 miles per h They arrive at LaTanya’s house at 3:30 P.M. How far is Marta’s house from LaTanya’s house?

Answers

The answer should be 3.1 miles

Marta's house is 3.10 miles from Latanya's house

What is speed?

Speed is defined as the ratio of the time distance traveled by the body to the time taken by the body to cover the distance.

Given that Latanya leaves her house at 12:30 p.M. She bikes at 12 mi/hr to Marta's house She stays at Marta's house for 90 minutes Both girls walk back to Latanya's house at 2.5 mi/h They arrive at Latanya's house at 3:30 p.M.

We need to know how far is Marta's house from Latanya's house

∵ Latanya starts her trip at 12:30 p.M.

∵ She returns home at 3:30 p.M.

∴ The time of her trip is  → 3:30 - 12:30 = 3 hours

- But she stays at Marta's house for 90 minutes

∵ 1 hour = 60 minutes

∴ 90 minutes = 90 ÷ 60 = 1.5 hours

∴ The time from her house to Marta's house and from Marta's house to her house is → 3 - 1.5 = 1.5 hours

Assume that the distance from her house to Marta's house is d and the time from her house to Marta's house is t₁ and the time from Marta's house to her house is t₂

∵ Latanya bikes at 12 mi/h to Marta's house

∵ Distance = speed × time

∴ d = 12 × t₁

∵ Both girls walk back to Latanya's house at 2.5 mi/h

∴ d = 2.5 × t₂

Equate the two expressions of d

∴ 12  = 2.5  ⇒ (1)

∵ t₁ + t₂ = 1.5

Subtract  from both sides

∴ t₂ = 1.5 - t₁  ⇒ (2)

Substitute equation (2) in equation (1)

∴ 12t₁  = 2.5(1.5 - t₂ )

∴ 12  = 3.75 - 2.5

Add 2.5 t₁ to both sides

∴ 14.5t₁  = 3.75

Divide both sides by 14.5

t₁ = 15 / 38 hour

∴ She spends 15/58 hours biking Marta's house. Let's find d

∵ d = 12t₁

∴ d =  12 x ( 15 / 38 ) miles

Therefore, Marta's house is 3.10 miles from Latanya's house

Answer:

8.80

Step-by-step explanation:

The decimal is 8.8

What is Decimal?

A group of numbers between integers on a number line are known as decimals. They are merely an additional mathematical representation of fractions. Integers, also known as whole numbers, are represented to the left of the decimal point, while decimal fractions are represented to the right of the decimal point. The next place, which is (1/10)th or tenth place value, is (1/10) times smaller if we move immediately from the first place.

given:

8 4/5

Now, writing into normal fraction

8 4/5 = 44/5

Now, dividing the fraction

44/5 = 8.8

Hence, the decimal is 8.8

Starting at 1:00 p.m., the temperature changes -4 degrees Fahrenheit per hour. Write an equation to find how many hours it will take to reach -1 *F.

Answers

Answer:

35 x (-4x) = -1           (9 hours)

Step-by-step explanation:

If your original temperature is 35, you can place that as your first term. Knowing that the temperature changes by -4 degrees per hour, we can make "x" = the number of hours until we get to -1° F.

35 x (-4x) = -1

-4x = -36

x =  9

35 x (-4x) = -1  (9 hours)

Step-by-step explanation:

If your original temperature is 35, you can place that as your first term. Knowing that the temperature changes by -4 degrees per hour, we can make "x" = the number of hours until we get to -1° F.

35 x (-4x) = -1

What is Inequality?

Mathematical expressions with inequalities are those in which the two sides are not equal. Contrary to equations, we compare two values in inequality. Less than (or less than or equal to), greater than (or greater than or equal to), or not equal to signs are used in place of the equal sign.

Given:

What are Arithmetic operations?

Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions. The operator that performs the arithmetic operation is called the arithmetic operator.

- Subtraction operation: Subtracts the right-hand operand from the left-hand operand.

for example 4 -2 = 2

* Multiplication operation: Multiplies values on either side of the operator

For example 4*2 = 8

Given the following data;

A bottle of water is 2/3 full. You drink 3/4 of the water.

To determine the portion of the bottle of water that you drink.

To do this we would multiply 2/3 of a bottle of water by 3/4.

⇒ 2/3 × 3/4

⇒ 6/12

⇒ 1/2

Thus, you drink half of the water in the bottle is 2/3 full.

How many miles does Kevin drive per minute?
a) 11/30
b) 5/6
c)2 8/11
d) 3

Answers

Answer:  11/30 miles per minute

Step-by-step explanation:

To get miles per minute

Divide the distance by the time

5 1/2 ÷ 15 . Change 5 1/2  to an improper fraction 11/2

invert the divisor and multiply: (Multiply by the reciprocal of 15: 1/15)

11/2 × 1/15 = 11/30

Here, we are required to determine how many miles does Kevin drive per minute.

The number of miles Kevin drives per minute is 0.3667miles.

According to the question, Kevin drives 5 1/2 miles (5.5 miles) in 15 minutes.

To determine how many miles Kevin drives per minute, we need to determine Kevin's speed over the 15 minutes in which he covered 5.5 miles.

Speed = distance/time

Speed = 5.5miles/15minutes

Therefore, Speed = 0.3667 miles per minute.

Ultimately, Kevin drives 0.3667miles per minute.

At gas station Z, it is $3.42 per gallon. At gas station Y, it is $3.37 per gallon. Gas station Y is a better deal and the cost per gallon of the gasoline at the gas station with the greater cost (gas station Z), is $3.42

Gas station Y is cheaper than gas station Z

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

Given:

At Gas Station Z, the cost of 15 gallons of gasoline is $51.30

So, cost of 1 gallon at station Z

=51.30/15

= 3.42

and, At Gas Station Y, the cost of 5 gallons of gasoline is $16.85

So, cost of 1 gallon at station Y

=16.85/5
