Explain how you could write 45 3/8 in scientific notation

1 answer:

5 0

First you must change 3/8 into a decimal, so the number would be 45.375. To find scientific notation you have to move the decimal between a factor of 1-10. 4.5375 . You moved over the decimal once toward the left. so scientific notation would be 4.5375 X 10^1

The given table and equation represent the cost for carnival rides.

lozanna [386]

Answer:

The ordered pairs that are presented are (7, 99.5) and (3, 51.5)

Step-by-step explanation:

We are given the cost function of the carnival rides as

$c=15.5+12f$

which is a typical linear expression of the form $y=ax+b$ where here $y=c$ , $f=x$ , $a=12$ and $b=15.5$ . To check if an ordered pair i.e. a point $(x,y)$ , is represented by the table we can simply plug in the equivalent $x$ value in the equation, and check if the result matches the $y$ value.

So, lets assume that all points are given correctly and they are as follow:

$A. (7, 99.5)\\B. (75.5, 5)\\C. (3, 51.5)\\D. (123.5, 9)$

Now let us check each point with our function as follow:

Point A

$(7,99.5)\\\\c=15.5+12(7)\\c=15.5+84\\c=99.5$

So point A is part of the equation.

Point B

$(75.5,5)\\c=15.5+12(75.5)\\c=15.5+906\\c=921.5$

So point B is NOT part of the equation.

Point C

$(3,51.5)\\c=15.5+12(3)\\c=15.5+36\\c=51.5$

So point C is part of the equation.

Point D

$(123.5,9)\\c=15.5+12(123.5)\\c=15.5+1482\\c=1497.5$

So point D is NOT part of the equation.

Find the missing angle in a triangle with the given sides.

aksik [14]

Answer: 72 degree

Step-by-step explanation:

By Angle Sum Property,

53 + 100 + angle C = 180

153 + angle C = 180

angle C = 180 - 153

= 72 degree

Raquel and Van live in two different cities. As part of a project, they each record the lowest prices for a gallon of gas at gas

mylen [45]

Based on the information given, the true statement true about their gas-price data is A. Raquel’s data are most likely closer to $3.42 than Van’s data are to $3.78.

<h3>Solution to the gas-price data.</h3>

It should be noted that a standard deviation simply measures how dispersed the data will be in relation to the mean.

From the complete question, the mean of Raquel's data is given as 3.42 while the standard deviation is given as 0.07. On the other hand, the mean of Van's data is given as 3.78 while the standard deviation is given as 0.23.

Therefore, it can be deduced that Raquel’s data are most likely closer to $3.42 than Van’s data are to $3.78.
