Marissa drives from her house to work at an avg speed of 40mph. She drives home sameroute at 60mph. Entire round trip is 45 minutes, what is her avgspeed in mph?

Answers

Answer:

50mph

Step-by-step explanation:

to to find the mean you add 40 + 60. which equals 100 then divide by the amount a variables which is two.

50 mph is correct. The 45 minute round trip is actually useless information in answering this question. You can divide 60+40 by 2 or in this case, when you only have 2 numbers to look at, you can find the median and the median will be the same as the mean. Unless you’re very comfortable with finding averages, I wouldn’t suggest calculating this by the median, but that is what I did because I’m very familiar with the pattern of finding means.

Answer:

Step-by-step explanation:

Look at tenth place. If it is 5 , 6 ,7 , 8, 9 ( 5 or more than 5)then add 1 to the whole part and that is your answer

If it is 0,1,2,3,4, then write the whole number as it it.

a) 8.71

tenth place is 7 and it is more than 5. so, add 1 to the whole part. 8+1 = 9

8.71 = 9

b) 26.01

Tenth place is 0 and it is less than 5.So, write the whole number as it is.

26.01 = 26

c) 69.48 = 69      { 4 is less than 5}

d) 103.72 = 104   { 7 >= 5}

e) 49.84 = 50  { 8 >= 5}

f)101.35 = 101  

g) 39.814 = 40

andrea is three times older than eliza. suzie is 4 years older then eliza. if eliza's age can be represented by x, create an expression that represents the combined age of all three girls

Answers

Answer:

Combined age = 5x+4 years

Step-by-step explanation:

let Eliza's age be x

given that Andrea is three times older than Eliza, hence Andrea's age is

= 3x years

it is also given that Suzie is 4 years older than eliza, hence Suzie's age is

= (x + 4) years

Therefore the combined age

= Eliza's age + Andrea's age + Suzie's age

= x   +   3x     +     (x+4)

= x + 3x + x + 4

= 5x + 4

A coin was tossed 60 times and the coin landed on Heads 35 times. What proportion of the time did the coin land on Heads?
Type your numeric answer and submit

Answers

Answer:

35:60 times

Step-by-step explanation:

The proportion of time in which the coin land on Heads is 0.58

What is proportion?

A proportion is an equation in which two ratios are set equal to each other.

Now it is given that,

Number of times coins tossed = 60

Number of times coin landed on Heads = 35

Therefore, the proportion of time in which the coin land on Heads is given as,

Proportion of time the coin land on Heads = Number of times coin landed on Heads/Number of times coins tossed

⇒ Proportion of time the coin land on Heads = 35/60

⇒ Proportion of time the coin land on Heads = 7/12 = 0.58

Thus, the proportion of time in which the coin land on Heads is 0.58

Answer:

1 inch= 4 feet for both

Step-by-step explanation:

This also means that the scale converts to 1/4 in. = 12 in.

stay safe

Using proportions, it is found that the scale is of 0.25 inches per feet.

This question is solved by proportions, using a rule of three.3 inches represents 12 feet, while 6 inches represents 24 feet. Since they are multiples, we take one of them, and find how many inches are represented by 1 feet.

The rule of three is:

3 inches - 12 feet

x inches - 1 feet

Applying cross multiplication:

[tex]12x = 3[/tex]

[tex]x = \frac{3}{12}[/tex]

[tex]x = \frac{1}{4}[/tex]

[tex]x = 0.25[/tex]

The scale is of 0.25 inches per feet.
