A motorcycle can travel 70 miles per gallon. Approximately how many gallons of fuel will the motorcycle need to travel 60 km?

[1 mile = 1.6 km]
0.2
0.5
0.8
1.4

Answers

We have the following given
mileage = 70 miles per gallon
distance = 60 km

Required: amount of fuel in gallons

First, we must convert the distance to miles, so
60 km (1 mi/1.6 km) = 37.5 mi

So, the amount of fuel is
37.5 mi / (70 mi/gal) = 0.54 gallons

Answer:

Step-by-step explanation:

if our motorcycle use 70 miles per gallon

and 1mile=1.6 km

the motorcycle travels 70*1.6=112 km per gallon

for 60 km it needs

60/112=0.54 gallons

The sum of the digits of a two − digit number is 11. The unit's digit is 7 less than the ten's digit. Find the number.

Answers

Answer:

Number = 92

Step-by-step explanation:

Let the unit digit is x and that of tens digit is y.

ATQ,

x+y = 11 ....(1)

The unit's digit is 7 less than the ten's digit

x = y-7 ...(2)

Put the value of x from equation (2) in (1)

y-7+y = 11

2x-7 = 11

2x = 11+7

2x = 18

x = 9

Put the value of x in equation (1)

9+y = 11

y = 2

Hence, the number is 92.

Use the provided ruler to find the scale and the scale factor of the drawing. The scale measures 4 centimeters equal to 120 meters. The scale factor is ?

Answers

Answer:

1 : 3000

Step-by-step explanation:

Given that:

Scale measurement as following:

4 centimeters are equal to 120 meters.

To find:

The scale factor = ?

Solution:

First of all, let us learn about the definition of scale factor.

Scale factor means 1 unit on scale is equal to what length of actual measurement.

We are given that 4 cm on scale is equal to 120 meters of actual length.

We need to find nothing but how much 1 cm of scale is equal to actual length.

4 cm of scale = 120 meters or 12000 cm of actual length

Dividing by 4 on both sides, we get:

[tex]\frac{4}{4}[/tex] = 1 cm of scale = [tex]\frac{12000}{4}[/tex] = 3000 cm of actual length

Therefore, the scale factor is 1 : 3000

The scale factor is 1; 3000.

Given

The scale measures 4 centimeters equal to 120 meters.

What is the scale factor?

The scale factor is a measure for the identical shapes, which look identical but have various scales or measures.

Scale factor means 1 unit on the scale is equal to what length of actual measurement.

4 cm of scale = 120 meters or 12000 cm of actual length.

1 cm of scale = 4/4

Then,

[tex]= \dfrac{12000}{4}\\\\=3000[/tex]

Hence, the scale factor is 1; 3000.

Answers

Answer:

12.4 feet

 Proportion of giraffe's height vs the height of its shadow = 16/24 = 2/3

If Dustin's height is x feet tall, then the proportion of his height and the height of his shadow (93/5 feet)should be the same as that of the giraffe, which is 2/3

 

so,

x/93/5 = 2/3

Multiplying both sides with 93/5

 

x = 2/3 * 93/5

x = 62/5 =12.4

Since angle B is the largest angle, line segment AC is the
side,

Answers

The answer would be b because AC don’t make sense

The line segment AC (side a) is the longest side of triangle ABC.

To determine which side of triangle ABC is the longest, we can use the concept that the side opposite the largest angle in a triangle is the longest side. In this case, angle B is the largest angle with a measure of 75 degrees.

Now, we can identify the side opposite angle B, which is line segment AC. Therefore, line segment AC is the longest side of triangle ABC.

To calculate it more formally, we can use the law of sines. The law of sines states that in any triangle, the ratio of the length of a side to the sine of its opposite angle is the same for all three sides. The formula is:

a/sin(A) = b/sin(B) = c/sin(C)

Where:

a, b, c are the side lengths of the triangle.

A, B, C are the angles opposite to sides a, b, c, respectively.

Let's calculate the length of side AC (a) using the law of sines:

a/sin(A) = b/sin(B) = c/sin(C)

a/sin(45°) = b/sin(75°) = c/sin(60°)

a/√(2) = b/sin(75°) = c/sin(60°)

Now, we know that b < a and c < a because angle B is the largest angle. So, to find the value of a, we need to solve for it.

a = √(2) * b and a = (√(3)/2) * c

Now, we have three sides in terms of one variable (a, b, and c), and we know that a > b and a > c. Therefore, line segment AC (side a) is the longest side of triangle ABC.

what ordered pair is a solution to the equation y= -2/3x + 9?
(-3/2, 10), (0, 10), (-1, 10 2/3), (2/3, 10)

Answers

Answer:

(-3/2, 10)

Step-by-step explanation:

(x, y)

Set y = 10

10 = -2/3(x) + 9

x = -3/2

(-3/2, 10)

Set y = 10 2/3

10 2/3 = -2/3(x) + 9

x = -5/2

(-5/2, 10 2/3)

You can also plot the line and see which point is on the line which would be (-3/2, 10).

The ordered pair that represents the solution to y= -2/3x + 9 is: A.  (-3/2, 10)

Recall:

An ordered pair, (x, y) is a solution to a given equation if we plug the x and y values of the ordered pair and the equation remains TRUE.

Thus, plug in the ordered pair, (-3/2, 10) into y= -2/3x + 9:

10 = -2/3(-3/2) + 9

Simplify

10 = 1 + 9

10 = 10 (TRUE)

Therefore, the ordered pair that represents the solution to y= -2/3x + 9 is: A.  (-3/2, 10)
