Answer:
x = 25
Step-by-step explanation:
The sum of the angles of a triangle are 180 degrees
2x+ x+15 +90 = 180
Combine like terms
3x+ 105 = 180
Subtract 105 from each side
3x+105-105 = 180-105
3x = 75
Divide each side by 3
3x/3 = 75/3
x = 25
The value of X is 25 degree.

20. In the figures below, the cube-shaped box is 6 inches wide and the rectangular box is 10 inches long, 4 inches wide, and 4 inches high. How much
of the cube-shaped box than the rectangular box?
A. 50 cubic inches
B. 60 cubic inches
C. 66 cubic inches
D. 56 cubic inches
Answers
Answer:
56 cubic inches
Step-by-step explanation:
Volume of cube box = 6^3 = 6 *6*6 = 216 , Volume of rectangular box = 10*4*4 = 160 . Difference = 216 - 160 = 56 cubic inches. 56 cubic inches greater is the volume of the cube-shaped box than the rectangular box.
Answer:
Step-by-step explanation:
cube volume=side^3
given that the side is 6, the volume is 6^3 or 216 cubic inches
volume regular rectangular prism=length times width times height
given that length=10, width is 4 and height is 4, volume=10*4*4=160 cubic inches
how much greater
216-160=56
it is 56 cubic inches greater

Find the probability of the outcome
Answers
Step-by-step explanation:
Total marbles = 2 + 4 +1 + 8 = 15 marbles
Probability of blue marble = 4 / 15
Probability of green marble = 2 / 15
Answer:
4/105
Step-by-step explanation:
Total number of marbles: 2 + 4 + 1 + 8 = 15
Number of blue marbles: 4
First drawing:
p(blue marble) = 4/15
Now there are 14 marbles left.
Number of green marbles: 2
p(green marble) = 2/14 = 1/7
p(blue then green) = p(blue) * p(green) = 4/15 * 1/7 = 4/105
Answer: 4/105

What is mean by Graph?Graph is a mathematical representation of a network and it describes the relationship between lines and points.
Now, From 0-4 the graph is uniformly increasing which represents 3 hours that's it's moving.
Then from 2-3 there no increment or decrement which represents it is in rest.
Then, from 4 - 5 the graph is uniformly increasing again which represents 1 more hours it is moving.
Hence, We get;
⇒ It travels for 3 hours, then stops for 1 hour, and finally travels again for 1 hour.

Write the equation of a line that passes through (4,-10) and has a slope of 2, please!
Answers
Answer:
y = 2x - 18
Step-by-step explanation:
There are lots of different methods to do these types of questions, but this is the way i like to do it.
Coordinate (x1, y1) : (4, -10) and Gradient (m): 2
Start with this generic equation:
y- y1 = m(x-x1)
Substitute in the values they have given you:
y - (-10) = 2(x-4)
This becomes:
y + 10 = 2x - 8
Keep solving by moving the 10 over to the other side:
y = 2x -8-10
y = 2x - 18
An easy way to double check:
1) the coefficient of x is the slope. We got 2x, and the slope is 2, so that's correct.
2) Substitute x=4 into the equation, and we get -10, which is the exact coordinate that they gave us. This is also right.

Answer:
2
Step-by-step explanation:
slope= [tex] \frac{y1 - y2}{x1 - x2} [/tex]
Thus, slope of the line
[tex] = \frac{4 - 2}{ - 1 - ( - 2)} \\ = \frac{2}{2 - 1} \\ = \frac{2}{1} \\ = 2[/tex]
