In the figure, BC is a support for the roof
of a garage. What is the length of BC?
Answers
Answer:
Bc = √63 ft
Step-by-step explanation:
Here, we want to get the length of BC
As we can see, there is a right angled triangle ABC, with 12ft being the hypotenuse and 9 ft the other side
So we want to get the third leg which is BC
we can use the Pythagoras’ theorem here
And that states that the square of the hypotenuse equals the sum of the squares of the two other sides
let the missing length be x
12^2 = x^2 + 9^2
144 = x^2 + 81
x^2 = 144-81
x^2 = 63
x = √63 ft

1 cubic foot = 6.23 gallons
1 cubic foot = 0.028 cubic metres
Convert 3738 gallons into cubic metres.
Answers
Answer:
16.8 cubic metres
Step-by-step explanation:
Given: 1 cubic foot = 6.23 gallons
1 cubic foot = 0.028 cubic metres
Let the conversion into cubic metres be represented by x.
Thus we can say that;
6.23 gallons = 0.028 cubic metres
and
3738 gallons = x cubic metres
So that,
x = [tex]\frac{3738*0.028}{6.23}[/tex]
= 16.8
x = 16.8 cubic metres
The conversion of 3738 gallons into cubic metres is 16.8 cubic metres.

Step-by-step explanation:
Like Terms
To be considered similar or like terms, two or more terms must have the exact same variables with the exact same exponents, regardless of the coefficients. For example, the following are like terms:
[tex]x, 5x, -3x, 2/5x[/tex]
[tex]3ab^2, -1/2ab^2, 7b^2a[/tex]
The following are not like terms:

We need to find which of the given terms are not considered to be like terms with the expression [tex]-6s^2t[/tex]. The variable s must be squared and the variable t must have an exponent of 1.
Applying the above definition, the following expressions are not like terms:

What is the slope of y=-1+3x
Answers
Answer:
That is the format for a slope so you already have it but its incorrect
Step-by-step explanation:
Slope format is y=mx+b
Your x shouldnt be next to the 3
This question isnt accurate or your missing information
====================================================
Explanation:
Because we can add two numbers in any order, the equation y = -1+3x is the same as y = 3x+(-1).
Compare this to y = mx+b, which is slope intercept form.
We see that m = 3 is the slope and b = -1 is the y intercept.

y=7x-32
Step-by-step explanation:
Since the line is parallel to y=-7x+5, it will have the same slope
use the slope-intercept form to find b, y=7x+b
plug the points into the equation
(-4)=7(4)+b
simplify
-4=28+b
subtract 28 from both sides
b= -32
plug b into the equation
y=7x-32

Regular pentagon MNQR similar to pentagon TUVWX. What scale factor was used dilate regular pentagon MNPQR to Pentagon TUVWX?
Answers
Answer:
. Since the pentagon is a regular pentagon, the measure of each interior angle will be the same.
To find the size of each angle, divide the sum, 540º, by the number of angles in the pentagon.
(which is the same as the number of sides).
540° ÷ 5 = 108° There are 108° in each interior angle of a regular pentagon.
2. 540°
Sum of Interior Angles of a Polygon
A pentagon has five sides, thus the interior angles add up to 540°, and so on.

What is the scale factor?
please help!
Answers
Answers:
Scale factor = 5/3 (which is approximately equal to 1.67)x = 10========================================
Work Shown:
To find the scale factor, we divide a side of triangle MNO over a corresponding side of triangle FGH. We can only pick the horizontal bottom sides since we don't know what x is yet.
scale factor = ON/HG = 15/9 = (5*3)/(3*3) = 5/3
In decimal form, this is approximately 5/3 = 1.67; however, I find it's better to stick with the fraction since it's exact.
---------------
Let's solve for x
One way to do so is to follow these steps
(FG)/(MN) = (HG)/(ON)
6/x = 9/15
6*15 = x*9 ..... cross multiply
90 = 9x
9x = 90
x = 90/9
x = 10
Or we could solve like this
(FG)/(HG) = (MN)/(ON)
6/9 = x/15
6*15 = 9x
90 = 9x
9x = 90
x = 90/9
x = 10
We end up with the same result because we got to 90 = 9x after cross multiplying, which was found in the previous set of steps as well. There are other ways to solve using a proportion. But they should all lead to x = 10.
Note how,
MN/FG = 10/6 = (5*2)/(3*2) = 5/3
which was the scale factor we found earlier
5/3 is going to be your answer.

Two airplanes leave an airport at the same time on different runways. One flies on a bearing of N 66°W at 325 miles per hour. The other airplane flies on a bearing of S 26°W at 300 miles per hour. How far apart will the airplanes be after two hours
Answers
If correct, can you mark as brainliest?
After solving the equations, the distance between two airplanes after two hours will be equal to 861.21 miles.
What is Speed?The speed of an entity, which is a scalar quantity in regular usage and kinematics, can be defined as the size of the change in direction per unit of time or the size of the change in position over time for an object. The initial speed is the upper limit of maximum pace as the duration of a time interval gets closer to zero.
Assume that both the planes are on similar point A at the start.
Assume that x is the 325 mph flying object.
Consequently, it would have traveled a distance of after two hours of 325 × 2 = 650 miles.
Let B represent the location of the plane two hours later.
That means AB = 650 miles
Assume that y is the 300 mph flying object.
It would have traveled a distance of two hours = 300×2=600 miles.
After two hours, let C represent the location of the second plane.
This means AC=600 miles
After two hours, BC separates the two aircraft.
So, the angle between their paths is 87°.
Cos A = (AC² + AB² - AC²)/(2(AC)(AB))
cos 87 = (600² - 650² - AC²)/(2 × 600 × 500)
40822.04 = 782500 - AC²
AC² = 782500 - 4082204
AC = 861.21 miles.
