6. A train travels 283. 8km in 4. 4 hours; how far does it travel in
(a) 1 hour
(b) 2. 5 hour​

Answers

Answer 1

If a train travels 283. 8km in 4. 4 hours, the train travels 71km in 1 hour and the train travels 114.5km in 2.5 hours.

Based on the assumption that the train is traveling at a constant speed throughout its journey.

To find the speed the train travels , we divide the total distance by the total time:

speed = 283.8km/ 4.4 hours

speed = 64.5 km/h

To find the distance the train travels , we multiply the speed of the train by the total time:

Distance travelled in 1 hour = 64.5 km/ hour × 1 hour

Distance travelled in 1 hour = 64.5 km

Distance travelled in 2.5 hours = 64.5 km/hour x 2.5 hours

Distance travelled in 2.5 hours = 161.25km

Given g(x) = -4x - 4, find g(-2).

Answers

Answer:

4

Step-by-step explanation:

Solution

This question basically asks you to substitute the value of x to find the value of function g(x).

Given x = -2,

g(-2) = -4(-2) - 4 = 8 - 4 = 4

Answer:

4

Step-by-step explanation:

g(x) = -4x - 4

Let x = -2

g(-2) = -4(-2) - 4

One car traveled 240 miles and drove 20 mph hour faster than a second car drove 160 miles. If the cars were traveling for the same time, how fast was the first car driving?
a. 90 mph
b. 80 mph
c. 50 mph
d. 60 mph

Answers

The answer is D because car 1 drove 20 mph faster than car 2. If car 1 drove at 60 mph for 4 hours it reaches 240 miles. Car 2 at 40 mph would travel 160 in 4 hours.

Sarah had 6 yards of ribbon. She needs 1 1/4 yards of ribbon for her project. How many complete ribbons can she cut from the 6 yards

Answers

Answer:

4 complete ribbons

Step-by-step explanation:

From the above question,

We can deduce that a project = complete ribbons

Hence,

1 1/4 yards = 1 complete project

6 yards = x

Cross Multiply

1 1/4 yards × x = 6 yards × 1 complete project

x = 6 yards ÷ 1 1/4 yards

x = 6 yards ÷ 5/4 yards

x = 6 yards × 4 yards/5

x = 24 /5

x = 4 4/5 complete projects(ribbons)

Therefore, she can cut 4 complete ribbons from 6 yards

What is the solution for 3x 2y 5?

Answers

The solution for 3x 2y 5 is x = 0 and y = -2.5

The solution for 3x 2y 5 can be found by first rewriting the equation in standard form, which is ax + by = c. In this case, the standard form would be 3x + 2y = -5.

Next, we can calculate the value of y in terms of x by using the following formula:

y = (c - ax) / b

Substituting in the values, we get:

y = (-5 - 3x) / 2

Now, we can substitute this expression for y into the original equation to solve for x:

3x + 2((-5 - 3x) / 2) = -5

3x + (-5 - 3x) = -5

6x + -5 = -5

6x = 0

x = 0

Finally, substituting x = 0 into the expression for y, we get:

y = (-5 - 3(0)) / 2

y = (-5 - 0) / 2

y = -5 / 2

y = -2.5

The solution for 3x 2y 5 is x = 0 and y = -2.5

The equation of line p is y= 1 4 x–8. Line q, which is parallel to line p, includes the point (6, – 3). What is the equation of line q?

Answers

Answer: y = 14x - 81.

Step-by-step explanation:
1. Since the lines are parallel to each other, that means they have the same slope, which is 14.
2. To find the equation of line q, you would need to use the point-slope equation, which is y2 - y1 = m (x2 - x1) and input the values of point (6, -3).
3. The equation you need to solve after inputting values would be y + 3 = 14 (x - 6).
4. Simplify the equation by distributing 14 into the parentheses. This would give you y + 3 = 14x - 84.
5. Now, subtract 3 on both sides to get the y alone. This should give you y = 14x - 81.

Answer:

The equation of line q in slope-intercept form is

y= 1/4 x– 9/2

Answer:

x = 10

Step-by-step explanation:

According to Midpoint of a segment theorem we can say that AE = EC

So,

2x - 10 = 8x - 70

=> First subtract 2x from each side of "="

-10 = 6x - 70

=> Now add 70 to both the sides.

60 = 6x

=> Lastly divide both sides of "=" by 6

A and B are vertical angles. A=(x+15) B=(5x−17) the measure of b

Answers

Answer = 23 degrees

Explanation

1. Since vertical angles are congruent you can set the equations equal to one another like x+15 = 5x-17.

2. Subtract x on both sides to combine like terms . That gives 15 = 4x - 17

3. Add 17 on both sides to combine like terms. That gives 4x = 32.

4. Divide 4 on both sides to solve for x. That results in x = 8.

5. To find the measure of b, you can input 8 into A since A=B and it’s quicker math. So 8 + 15 = 23 degrees

Find the measure of the indicated angle to the nearest degree.

Answers

Answer:

70⁰

Step-by-step explanation:

We need to use the knowledge of trigonometry to find the indicated angle. Given the information in relation to the angle we have the opposite and the hypotenuse.

we therefore use Sine in this calculations

Sin ? = opposite/ hypotenuse

= 16/17

= 0.9412

to get the angle we get the sine inverse

Sine inverse of 0.9412 = 70.25⁰

= 70⁰

Answer:

? ≈ 70°

Step-by-step explanation:

using the sine ratio in the right triangle

sin ? = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{16}{17}[/tex] , then

? = [tex]sin^{-1}[/tex] ( [tex]\frac{16}{17}[/tex] ) ≈ 70° ( to the nearest degree )
