In a traffic survey, some bikes buses and cars were recorded. 70% of the vehicles were cars and 17% were buses. What percentage were bikes? Show me your work please!

Answers

Percent is calculation of quantity per 100 quantity of other thing. The percentage of bikes out of of total surveyed vehicles was 13%

How to find the percentage from the total value?

Suppose the value of which a thing is expressed in percentage is "a'

Suppose the percent that considered thing is of "a" is b%

Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then we multiply it with b so that we collect b items per 100 items(that is exactly what b per cent means).

Thus, that thing in number is

$(a)/(100) * b$

Assume that total T number of vehicles were surveyed.

Then, as it is given that 70% of the vehicles were cars and 17% were buses.

So, number of cars = $(T)/(100) * 70 = (7 * T)/(10) = 0.7 * T$

Similarly, the number of buses = $(T)/(100) * 17 = 0.17 * T$

Thus, number of bikes = Total vehicles - number of cars and buses

Number of bikes = T - 0.7T - 0.17T = T(1 - 0.87) = 0.13T

Taking its percentage with total vehicles, let it be x% of total vehicles, then

$0.13T = (T)/(100) * x\n\n\text{Multiplying 100/T on both the sides}\n\n13 = x\nx = 13$

(we could have used short cut that total there is 100%, since number of cars = 70% of total, number of buses = 17% of total, thus

total vehicle's percent being bike = all vehicle (100%) - percent of cars - percent of buses) = (100 - 70 -17)% = 13% )

Thus, the percentage of bikes out of of total surveyed vehicles was 13%

Answer:

13%

Step-by-step explanation:

There are three groups: bikes, buses, and cars. The percentages of each must add up to 100%.

bikes + buses + cars = 100%

bikes + 17% + 70% = 100%

bikes + 87% = 100%

bikes = 13%

Which list orders the numbers from least to greatest? |-2.4|,|-1.5|,-2 1/2|,|-3|, |-1 1/8|

Answers

Answer:

the answer is D

Step-by-step explanation:

Sorry if i get it wrong

Final answer:

The ordered list from least to greatest using the absolute values would be: |-1 1/8|, |-1.5|, |-2 1/2|, |-2.4|, |-3|.

Explanation:

The student is asking to order a series of numbers from least to greatest. The numbers given are in absolute values. Absolute value refers to the distance of a number from zero, disregarding whether it is negative or positive. Therefore, the |-2.4| signifies the absolute value of -2.4, which is 2.4. Similarly, the other numbers convert to 1.5, 2.5, 3, and 1.125 respectively.

To answer this question, we must understand that the smaller the absolute value, the closer the number is to zero. Hence, the order from smallest (or least) to largest (or greatest) would be: |-1 1/8|, |-1.5|, |-2 1/2|, |-2.4|, |-3| .

To make a monster appear large in a movie, a human actor wore a costume and walked through a scale model of a city. The scale used was 1 inch = 15 feet. The actor is 60 inches tall. How tall does the monster appear in the movie?Question 5 options:

720 feet

75 feet

4 feet

900 feet

Answers

Answer:

Option D is correct.

900 feet tall does the monster appear in the movie

Step-by-step explanation:

Proportion states that the two ratios or fractions are equal

As per the statement:

To make a monster appear large in a movie, a human actor wore a costume and walked through a scale model of a city.

Scale used was:

1 inch = 15 feet.

It is also given that: the actor is 60 inches tall

To find how tall does the monster appear in the movie

Let x be the height of the Monster appear in the movie.

by definition of proportion we have;

$(1)/(15) =(60)/(x)$

By cross multiply we have;

$x = 15 \cdot 60$

Simplify:

x = 900 feet

Therefore, 900 feet tall does the monster appear in the movie
