Mathematics Middle School

You get out of school and walk north for 20 minutes. You

travel 1. 6 km. What is your average velocity?

1

Answers

Answer 1

Answer:

Step-by-step explanation:

Velocity is change in displacement over change in time.

v = d/t

In this problem, d = 1.6 km and t = 20 minutes

To find the velocity, divide 1.6 by 20, and you get 0.08 km/min.

You could also convert this to km/hour by dividing 1.6 km by 1/3 hours, and the velocity would be 4.8 km/hour.

Answer 2
4.8 km/hour because you times everything by 3

Answer: 160

Step-by-step explanation:

Answer: 160m3

Step-by-step explanation:

For the first prism, you find the volume by multiplying the length of the prism by the width of the prism by the height of the prism.

V = w h l = 8m x 3m x 2m = 48m3

For the second prism, you do the same thing you did to the first one.

V = w h l = 4m x 4m x 7m = 112m3

Lastly, you add the volume of both prisms to get your answer.

48m3 + 112m3 = 160m3

Answer:

[tex](7a \cdot 5b) \div 6c \cdot 2d[/tex]

Step-by-step explanation:

If there is both multiplication and division in an expression and no parentheses, you start solving from left to right. Since in the expression [tex]7a \cdot 5b \div 6c \cdot 2d[/tex] you would start by solving [tex]7a \cdot 5b[/tex], (because it's at the leftmost part of the expression) it won't matter whether you put parentheses around [tex]7a \cdot 5b[/tex] or not. Therefore, the expression [tex](7a \cdot 5b) \div 6c \cdot 2d[/tex] is equivalent to [tex]7a \cdot 6b \div 6c \cdot 2d[/tex].

Answer:
7a*5b/6c*2d (the last one is the correct answer)

Answers

Answer:

6 possible outcomes

Step-by-step explanation:

Given:

Flip a coin

Draw a marble at random  from a bag containing two purple marbles and  one white marble

To Find:

The possible outcomes = ?

Solution:

By Flipping a coin, we have two outcomes, either head or tail

For each of these outcomes we will either tale any one of the balls from the  bag

So possible outcomes will be

Head - purple ball

head -purple ball

Head -white ball

Tail  - purple ball

Tail  -purple ball

Tail  -white ball

So there are 6 possible outcomes.

Answers

Answer:

8 bags of snacks

Step-by-step explanation:

After mixing each snack, there will be a total of 8 cups of snack mix.

With 8 cups of snack mix being divided, and having one cup of snack mix in each bag, there will be a total of 8 snack bags.

8 snack bags

If Susie mixed 6 and 2, it’ll become 8 cups in total of the snack mix. In each snack bag there’s 1 cup, so there would be 8 snack bags.

In the morning, the temperature was
–
10°C. By the afternoon, it had risen to
–
2°C. What was the change in temperature from the morning to the afternoon?

Answers

Answer:

Change in temperature is +8° C

Step-by-step explanation:

Change in temperature = Final temperature - Initial temperature:

                                =ΔT = [tex]F_{T} - I_{T}[/tex]

                                        = (- 2° C)- (- 10° C)

                                        = [tex]- 2 + 10[/tex]

∴ Change in temperature  = + 8° C

If in the morning is was 10 degrees C then that means the temperature dropped 8 degrees C by the time it was the afternoon, but if it was 2 degrees C in the morning, that means it rose 8 degrees by the afternoon

Step-by-step explanation:

(45 - 32) / 32) * 100 = 40.63 %

To round 40.63 to the nearest whole number consider the tenths’ value of 40.63, which is 6 and equal to or more than 5. Therefore, we have to round up: the whole number part of 40.63, 40, increases by 1 to 41, and the decimal point and all digits (.63) are removed...

40.63 rounded to the nearest whole number = 41

Answer:

Step-by-step explanation:

if the equation is 9=3(x+2), what does x equal?

Answers

9=3(x+2)
9=3x+6
3x=3
x=1

Answer:

1

Step-by-step explanation:

To solve for x, we can isolate x on one side of the equation by undoing the operation of the expression inside the parentheses. To do this, we need to subtract 2 from both sides of the equation:

9 = 3(x + 2)

9 = 3x + 6

3 = 3x

Finally, we divide both sides by 3 to obtain:

x = 1

So, the value of x is 1.
