(A journey by bus takes 45 minutes at 60 km per hour. How fast must a car go to do the same
journey in 25 minutes? plzz answerr!!! this is my third time asking this question:(​

Answers

Answer 1

Answer:

The car must go at 108 km per hour

Step-by-step explanation:

Let us solve the question

∵ A journey by bus takes 45 minutes at 60 km per hour

∴ The speed of the bus = 60 km per hour

∴ The time of the journey = 45 minutes

→ Change the time from minutes to hours

∵ 1 hour = 60 minutes

∴ 45 minutes = 45 ÷ 60 = 0.75 hour

∴ The time of the journey = 0.75 hour

Distance = Speed × Time

→ Substitute the speed by 60 and the time by 0.75

∵ The distance that the bus traveled = 60 × 0.75

The distance that the bus traveled = 45 km

∵ A car goes to do the same journey in 25 minutes

∴ The distance that the car travels = 45 km

∴ The time that the car takes = 25 minutes

→ Divide it by 60 to change it to hours

∵ 25 minutes = 25 ÷ 60 = [tex]\frac{5}{12}[/tex] hour

∴ The time that the car takes =  [tex]\frac{5}{12}[/tex] hour

→ Use the rule of the distance above to find the speed of the car

45 = the car's speed ×  [tex]\frac{5}{12}[/tex]

→ Divide both sides by  [tex]\frac{5}{12}[/tex]

∴ 108 = the car's speed

∴ The car's speed = 108 km per hour

The car must go at 108 km per hour

Matt has 2/3 yard of fishing line. He uses 3/8 to make fishing knots. Shade the model to show the amount of line that Matt uses to make fishing knots?

Answers

Answer:

1/4 yards was to make fishing knot

Step-by-step explanation:

Given that :

Yards of fishing line = 2/3

Fraction used to make fishing knot = 3/8

Amount of yards used to make fishing knot;

3/8 of the number of yards was used to make fishing knot.

The side lengths 10, 14, and 15 form a triangle. Explain why.​

Answers

Answer:

Therefore, the side lengths 10, 14, and 15 form a triangle.

Step-by-step explanation:

The Triangle Inequality Theorem defines that if we are given the three sides of a triangle, then the sum of any 2 sides of a triangle must be greater than the measure of the third side of the triangle.

The three conditions that need to be met for any triangle with the side lengths A, B, and C.

[tex]A + B > C[/tex]

[tex]B + C > A[/tex]

[tex]A + C > B[/tex]

Given the side lengths of a triangle

101415

Let us check whether it satisfies the three conditions.

10+15 > 14     →  TRUE

10+14 > 15     →  TRUE

14+15 > 10    →  TRUE

As all the conditions are met. Therefore, the side lengths 10, 14, and 15 form a triangle.

Answers

The answer will be 1/10. First you will change the denominator to the same number because you can’t mutiply fractions if the denominator is different. 5x2=10 and 2x5=10. So both of the denominator will turn into a 10. Now you’ll have to find the numerator. For the first one, multiply it by 2 because that how much the number need to turn equalvilant for the denominator. 1x2=2. So now you know that the first fraction is 2/10. Then you multiply 1 with 5 which is 5. Now the numbers all have the same denominator. Multiply 2/10 and 5/10 which is 1/10.

Mrs girl burns 236 calories riding her bike each hour she wants to burn 590 calories riding her bike what ineqality reperesents the number of hours she must ride her bike

Answers

Answer:

Step-by-step explanation:

Amount of calories per hour whkie riding = 236

Amount of calories she intends to burn = 590

The number of hours she must ride her bike :

Let number of hours = x

Hence,

(Calories burned per hour * number of hours) ≥ 590

(236 * x) ≥ 590

x ≥ 590 / 236

x ≥ 2.5

Hence she must rise her bike for 2.5 hours

A line that models the data is given by the equation
y= 1.62x + 18 , where y represents the wait time,
and x represents the number of staff available.
The slope of the line is -1.62. What does this mean in
this situation?

Answers

Answer:

Kindly check explanation

Step-by-step explanation:

Give the line of best fit :

y = 1.62x + 18 ; where ;

y = wait time ; x = number of staffs available

If slope of the line is -1.62.

The slope of linear graph represents the ratio of change in the y variable and the x variable. With a slope value of - 1.62, the rate of change is negative and thus an increase in x will lead to a decrease in y. This means that for every unit increase in the number of staffs, the wait time reduces at a rate of 1.62 per unit.

Solve the system:
x + y = 19
y = 3x - 1

Answers

This is a simultaneous equation, and you can solve it using the substitution method. You can put the values for y into the first equation.

Therefore: x + (3x - 1) = 19

We can simplify this equation: 4x - 1 = 19

Next, we have to make 4x on its own, and so add 1 to both sides: 4x = 20.

To find x on its own, we have to divide both sides by 4: x = 5

To find the value of y, you can substitute the value of x that we just found out into the second equation: y = 3 x 5 - 1

Simplify: y = 14

Therefore, x = 5, and y = 14

Step-by-step explanation:

13x-4 = 8x+11

The value of AD is: AD = 35.

Here, we have,

from the given figure, we get,

both the triangles are similar to each other.

so, we have,

AD = DC

i.e.

13x-4 = 8x+11

To solve the equation 13x - 4 = 8x + 11, we need to isolate the variable x on one side of the equation.

Here are the steps:

Start by moving the terms with x to one side of the equation.

We can do this by subtracting 8x from both sides:

13x - 8x - 4 = 8x - 8x + 11

Simplifying the left side:

5x - 4 = 11

Next, move the constant term (-4) to the other side by adding 4 to both sides of the equation:

5x - 4 + 4 = 11 + 4

Simplifying:

5x = 15

To isolate x, divide both sides of the equation by the coefficient of x, which is 5:

(5x)/5 = 15/5

Simplifying:

x = 3

Therefore, the solution to the equation 13x - 4 = 8x + 11 is x = 3.

so, we get, x = 3

Plug it in AD, we have,

13(3) -4

=39-4

=35

Hence, The value of AD is: AD = 35.

Answers

Answer:

A

Step-by-step explanation:

because of the gravity of thw earth

Answer:

C. He would solve 32 math problems if he played video games for 8 hours.

Step-by-step explanation:

Create the following proportion to find the number of math problems for 8 hours:

4/16 = 8/x

Cross multiply.

4 x x = 4x

16 x 8 = 128

4x = 128

x = 32

If Tom plays video games for 8 hours, he'll solve 32 math problems.

Create the following proportion to find the number of math problems in 9 hours:

4/16 = 9/x

Cross multiply.

4 x x = 4x

16 x 9 = 144

4x = 144

x = 36

If Tom plays video games for 9 hours, he'll solve 36 math problems.

A professor wants to divide the remaining 3/4 of the semester evenly into six different units. What fraction of the semester should be spent on each unit?

Answers

Answer:

Each of these courses will take up 1/8 of the total semester.

Step-by-step explanation:

From the question, we can see that the semester is remaining 3/4 of the total duration.

we will be sharing that 3/4 into 6 places for each course. Next, we will be relating this to the total time we had for the whole semester initially.

3/4 divided by 6 = 1/8

From this, we can see that each of these  courses will take up 1/8 of the total semester.

Step 1: Subtract 3/4x from both sides.

1/4x − 5 − 3/4x=3/4x−12−3/4x

−1/2x−5=−12

Step 2: Add 5 to both sides.

−1/2x−5+5=−12+5

−1/2x=−7

Step 3: Multiply both sides by 2/(-1).

(2/−1)*(−1/2x)=(2/−1)*(−7)

2nd way

Add 5 to both sides

1/4x - 5+5 = 3/4x - 12+5

Simplify

1/4x = 3/4x -7

Subtract 3/4x from both sides

1/4x-3/4x= 3/4x-7-3/4x

Simplify

-1/2x=-7

Multiply both sides by -2

(-1/2x)(-2)=(-7)(-2)
