Answer:
12
Step-by-step explanation:
If the perimeter is 58,
take 17(2) for booth sides.
Which you will get 34.
58-34=24
Now you know that the remainder is the two vertical sides.
24/2=12
BC=12
Answer:
230°
Step-by-step explanation:
1. A quadrilateral is a 4-sided shape that consists of 2 triangles.
2. The interior angles in a triangle equal 180°: a quadrilateral has interior angles of 360°.
3. x° + 25° + 45° + 60° = 360°
4. x° + 130° = 360°
5. x° = 230°
Answer:
An equation of slope:
y = -5x+72
Step-by-step explanation:
The equation of slope intercept is given by:
where m is the slope and c is the y-intercept or initial value.
Let x represents the time in minutes and y represents the height of the water level
As per the statement:
The water level in Noah's water tank is 72 inches high.
At x = 0
y= 72
It is also given that:
The water drains at a speed up 5 inches per minute.
Here, m represent the slope in inches per minute
(as the water drains)
Substitute in [1] we get;
y = -5x+c
Substitute x = 0 then;
72 = -5(0)+c
72 = c
⇒equation becomes: y = -5x+72
Therefore, an equation of slope is y = -5x+72
We have the following expression:
(x ^ 2-9 / x ^ 2 + 2x-3) / (x ^ 2 + 6x-27 / x ^ 2-10x + 9)
Let's rewrite the expression:
(((x-3) * (x + 3)) / ((x + 3) * (x-1))) / (((x + 9) * (x-3)) / ((x-9) ) * (x-1)))
We cancel similar terms:
(1/1) / ((x + 9) / (x-9))
Doing double c we have:
(x-9) / (x + 9)
Answer:
B x-9 / x + 9
I think the answer is C.
I figured this out because if they asked 12 people and 8 thought that their boss is understanding and 96 people work there I figured they asked 1/8 of the workers and 4/6 thinks he is an understanding person.
96 divided by 12 = 8
96 divided by 6 = 16 and 16 x 4 = 64
Hope this helps.
