Shtirlitz [24]

For this case, the first thing we are going to do is rewrite the equation correctly.
We have then:
T = 50 + (N-40) / 4
We substitute the value of N = 98, we have then:
T = 50 + (98-40) / 4
T = 64.5 degrees Fahrenheit.
Answer:
the temperature in degrees Fahrenheit, T is:
T = 64.5 degrees Fahrenheit.

Example:

Aleonysh [2.5K]

Answer:

AB // CD and AD // BC, then ABCD is a parallelogram

Step-by-step explanation:

Step 2: Show AD // BC

A = (-3 , 3) and D = (0 , 0)

Find the slope of AD

$m_{AD}=\frac{0-3}{0--3}=\frac{-3}{3}=-1$

B = (2 , 5) and C = (5 , 2)

$m_{BC}=\frac{2-5}{5-2}=\frac{-3}{3}=-1$

The slope of AD = the slope of BC

So AD // BC because they have the same slope

Step 3:

Each two opposite sides are parallel in quadrilateral ABCD

So the quadrilateral is a parallelogram

Calculate the distance between each given pair of points. Round your answer to the nearest tenth, if necessary.

Ksju [112]

The answer is 5

Here are the steps:

First off, we will be using the distance formula of
$d=\sqrt{(x_ {2}- x_{2}) ^{2}+( y_{2}- y_{1})^2 }$

So we have the ordered pairs of (3,1) and (6,5)

Once you plug them into the formula it should look like this:
$d= \sqrt{(6-3)^2+(5-1)^2}$

Now we do the math inside the parenthesis and end up with:
$d=\sqrt{3^2+4^2}$

Then you multiply by the power and simplify to get:
$d=\sqrt{25}$

And the $\sqrt{25}$ =5

So your answer is 5

Part A A high school athlete ran the 100 meter sprint in 13.245 seconds. Round the time to the nearest tenth.Part B Explain how

amid [387]

Answer:

t = 13.2 s

Step-by-step explanation:

Given that,

An athlete ran the 100 meter sprint in 13.245 seconds. We need to round off the time to the nearest tenth.

Here, t = 13.245 s

In order to round off to the nearest tenth, thousandths place and hundredth place gets eliminated.

So, t = 13.2 s

So, time is 13.2 seconds.
