In a standard television set, the screen height is 0.75 times the screen width. If a television set measures 34 inches along the

S_A_V [24]

We can solve this by using the P<span>ythagorean theorem which is below:

$a^2 + b^2 = c^2$

Or we can say
</span> $w^2 + h^2 = d^2$
<span>w = widht
h = height
d = diagonal measure

With that said, we know the height is .75 times the width so .75w. We also know d = 34, which is our diagonal measure.
w = don't know yet but need to find
h = .75w
d = 34
Now lets plugin the information we know into our equation

</span> $w^2 + h^2 = d^2$
$w^2 + (.75w)^2 = 34^2$
Now lets to the math
$w^2 + (.75w)^2 = 34^2$
$w^2 + (.75w)^2 = 1156$
$w^2 + .5625w^2 = 1156$
Combine like terms
$w^2 + .5625w^2 = 1156$
$1.5625w^2 = 1156$
Divide both sides of the equal sign by 1.5625
$\frac{1.5625w^2}{1.5625} = \frac{1156}{1.5625}$
$w^2 = 739.84$
Now take the square root on both sides of the equal sign
$\sqrt{w^2} = \sqrt{739.84}$
$w = 27.2$

So the width is 27.2
We can check this by putting 27.2 back into our original equation
$w^2 + (.75w)^2 = 34^2$
$27.2^2 + (.75\times 27.2)^2 = 34^2$

Saige's spaceship traveled 588 588588 kilometers ( km ) (km)left parenthesis, start text, k, m, end text, right parenthesis in 6

pshichka [43]

Answer:

The first ship has the same speed as Saige's ship while the second and third do not have the same speed.

Step-by-step explanation:

d = Distance traveled by Saige's spaceship = 588 km

t = Time taken = 60 seconds

Speed is given by

$s=\dfrac{d}{t}\\\Rightarrow s=\dfrac{588}{60}\\\Rightarrow s=9.8\ \text{km/s}$

The other ships

$s=\dfrac{441}{45}=9.8\ \text{km/s}$

$s=\dfrac{215}{25}=8.6\ \text{km/s}$

$s=\dfrac{649}{110}=5.9\ \text{km/s}$

So, the first ship has the same speed as Saige's ship while the second and third do not have the same speed.

The chart has been completed in the picture attached.

Step-by-step explanation:

Step 1:

It is given that the number of bacteria doubles every 6 hours.

So if there are 1 million now, in 6 hours there would be double that i.e. 2 million and it will go on.

Step 2:

As the first column says the number of 6-hour periods, the second column is the actual number of hours.

So the second column is multiples of 6 so the second column is filled with;

0, 6, 12, 18, 24, 30, 36, 42 and 48.

Step 3:

The current population is calculated by multiplying the previous population by 2.

For 0 hours, the population = 3 million,

For 6 hours, the population = $2(3) = 6$ million,

For 12 hours, the population = $2(6) = 12$ million,

For 18 hours, the population = $2(12) = 24$ million,

For 24 hours, the population = $2(24) = 48$ million,

For 30 hours, the population = $2(48) = 96$ million,

For 36 hours, the population = $2(96) = 192$ million,

For 42 hours, the population = $2(192) = 384$ million, and

For 48 hours, the population = $2(384) = 768$ million.

So at the end of 48 hours, there will be approximately 768 million bacteria on the pinhead.
