Answer:

7.4 meters per second

Step-by-step explanation:

To find the average running rate in meters per second, we must divide the total number of meters by the total number of seconds.

meters/seconds

The sprinter ran 400 meters in 54 seconds.

400 meters/54 seconds

400/54

Divide

7.40740740741

Round to the nearest tenth. The zero in the hundreth place indicates that we keep the tenth place as is.

7.4

The runner's average rate is about 7.4 meters per second

Which ratio is equivalent to 4/16 A. 2:4•• B. 6 to 20 C. 8:32 D. 12 to 64 Write the ratio as a unit rate. 286 miles in 5 1/2 hou

NeX [460]

1) Which ratio is equivalent to [tex] \frac{4}{16} [tex]?
[tex] \frac{4}{16} * 2 = \frac{8}{32} [tex], or 8:32.

2) Write the ratio as a unit rate [tex] ( \frac{286miles}{5 \frac{1}{2} hours} ) [tex]
Set the equation up like this:
[tex] \frac{286miles}{5 \frac{1}{2} hours} = \frac{Xmiles}{1 hour}\\
286*1=(5 \frac{1}{2})*x\\
286 = \frac{11x}{2}\\
11x= 572 [tex]
x = 52 [tex] \frac{miles}{hour} [tex]

Sage has 3 strip-mats, 3 mats, and 2 units. Tristan has 2 mats, 8 strips, and 5 units. Andre had twice as many strip-mats, mats,

sladkih [1.3K]

The question is an illustration of equivalent equations.

<em>There are 11 units in all</em>

The given parameters are:

<u>Sage</u>

$\mathbf{Strip-mat = 3}$

$\mathbf{Mat = 3}$

$\mathbf{Units = 2}$

<u>Tristan</u>

$\mathbf{Strip-mat = 8}$

$\mathbf{Mat = 2}$

$\mathbf{Units = 5}$

Andre has twice of what Sage has

So, the total unit is:

$\mathbf{Total = Sage + Tristan + Andre}$

<em>Sage has 2 units</em>

<em>Tristan has 5 units</em>

<em />

Because, Andre has twice of what <em>Sage has,</em>

Andre's number of units would be 4

So, we have:

$\mathbf{Total = 2 +5 + 4}$

$\mathbf{Total = 11}$

Hence, there are 11 units in all

Answer:

$y=-x+1$

Step-by-step explanation:

Slope can be represented as rise over run (change y-values over change in x-values). Since the y-value is changing by -2 every time the x-value is changing by 2, the slope of the line must be $\frac{-2}{2}=-1$ .

In slope-intercept form $y=mx+b$ , $m$ represents the slope of the line, $b$ represents the y-intercept, and $(x, y)$ represent the coordinates of any point the line passes through.

To find $b$ , substitute $m=-1$ and any point the line passes through.

Using (1, 0) from the table:

$0=-1(1)+b,\\0=-1+b,\\b=1$

Thus, the equation of this line is $\boxed{y=-x+1}$

Scientific notation of 325•10^-8

USPshnik [31]

Given:

A number is

$325\times 10^{-8}$

To find:

The scientific notation of the given number.

Solution:

Scientific notation of a number is the product of a number between 1 to 10 and 10 to the power some integer.

We have,

$325\times 10^{-8}$

It can be written as

$325\times 10^{-8}=3.25\times 10^{2}\times 10^{-8}$

$325\times 10^{-8}=3.25\times 10^{2+(-8)}$

$325\times 10^{-8}=3.25\times 10^{-6}$

Therefore, the scientific notation of the given number is $3.25\times 10^{-6}$ .
