Answer:

10 (8.06)

Step-by-step explanation:

H^2 = p^2 + B^2

H^2 = (7^2) + (4^2)

= \sqrt{65\\

= 0.8622

round off to 10

Answer:

The answer is 8.3

Step-by-step explanation:

(I'm not that good at explaining things so bear with me please. I checked on Khan Academy so it's right)

I split the box on the right diagonally and got the equation

4^{2} + 2^{2} = x^{2}

=16 + 4 =\sqrt{20}

≈4.5

The new triangle will help solve what d is

4.5^{2} + 7^{2} = d^{2}

=20.25 +49 = \sqrt{69.25}

≈8.3

1. The heights of two right prisms
RoseWind [281]

Answer:

They are not similar

Step-by-step explanation:

To determine whether the prism are similar we need to calculate their volumes

Volume of a prism = Base Area * Height

Volume of the first prism = 18ft *8 * 8ft

Volume of the first prism = 1152ft^2

Volume of the second prism = 30t * 15 * 15ft

Volume of the second prism = 6,750ft^2

Since the volumes are different, the prism are not similar.

If we are given the value of α. How can we find the value of β?
Cloud [144]

Answer:

β = 140   - α

we know that the "missing" angle is 40° since 40 + 140 = 180

we also know that the total sum of angles in a triangle is 180

so  β = 180 - 40 - α

or β = 140   - α

HELP EMERGENCY!!!!!! What is the equation of the line?<br> Y=3x-1<br> Y=-3x<br> Y=3x+1<br> Y=3x
ch4aika [34]
<h2>Answer:</h2>

By process of elimination, we can eliminate:

  • <em>A:</em> <em>y = 3x - 1</em>
  • <em>C: y = 3x + 1</em>
  • <em>B: y = -3x</em>

<em>A and C</em> don't work because the given line has it's y-intercept at the origin, therefore, no y-intercept is written. <em>B </em>is not it either because the line <em>does not</em> go <em>down</em> from <em>left to right</em>, therefore, the slope is <em>not</em> negative.

The answer is <em>D: y = 3x</em> because since the line goes <em>up</em> from <em>left to right</em>, the slope is positive, and the y-intercept is the origin, so the equation will have no b.
