Answer:
12 x X x 1/2 = 54
12x x 1/2 = 54
x2 x2
12x = 108
divide by 12 on both sides:
X = 9
Let's double check!
9 x 12 = 108
108 divided by 2 = 54
IT WORKS!
Therefor your answer will be,
9!

find the equation of the line passes through the point (-1,2) and making an angle of 45° with the line x-y+1=0
Answer:
Step-by-step explanation:
line given is x-y+1= 0
you can rewrite it in slope intercept y=mx+b where m is the slope, and b is the y-intercept where the line meets the y-axis
x-y+1 =0 subtract x and 1 from both sides of the equation
-y = -x-1 multiply both sides by -1
y = x+1 so the slope of this line is 1 and the y-intercept is 1
If you draw this line you can see that there are actually 2 lines that form 45° angles with y=x+1 and pass through (-1, 2), one is vertical x= -1 and one horizontal y =2
The sine of the complimentary angle to 75 degrees
Answer: 0.65
Step-by-step explanation:
Two angles are said to be complementary angles when the sun of their angles will be equal to 90°. In this case, since the angle given is 75°, then the other angle will be:
= 90° - 75°
= 15°
Therefore, we'll then find the sine of 15° which will be:
= Sine 15°
= 0.65
Therefore, the correct option is A.

HIHI PLS help ;( having trouble </3
it says "The graph of the inequality y>-1/2x-2 should have the test point 0,0 shaded. true or false"
THANK YOU ヽ(=^･ω･^=)丿
Answer:
True
Step-by-step explanation:
Substitute in x = 0 and y = 0. If the statement is true, then (0, 0) is shaded.
y > -1/2x - 2
0 > -1/2(0) - 2 = -2
0 > -2 is true, so (0, 0) is shaded
Is it possible for two lines with negative slopes to be perpendicular? Justify your answer.
Answer:
No
Step-by-step explanation:
The slopes of perpendicular lines must always be the negative reciprocal of each other. If one slope is negative, for the other to be perpendicular to it, it must be positive, and vise versa.
Answer:
No
Step-by-step explanation:
Interesting question. Subtle.
The formula for two lines to be perpendicular is m1 * m1 = -1 That means that two lines cannot be minus -- only 1 of them can be. The reason is that if both were minus when multiplied together would give a positive result -- not minus one. For example, suppose you have
y = x + 2
y = 2x + 3.
These 2 lines will cross and they are not parallel, but neither are they perpendicular. I'm not going to solve this to find out where they cross -- that's not what you are asking.
Now suppose you have two other lines
y = - 2x + 3
y = 1/2 x + 1
These two lines should be perpendicular
-2 * 1/2 = - 1 which is the condition of perpendicular.

What is the volume of the following rectangular prism?
Answer:
Length * Height * Width, or V = L * H * W. Ex: V = 5 in.
Answer:
28
Step-by-step explanation:
We are given the area of a base and the width of the prism.
Volume = area of base * width
Volume = 8/3 * 21/2 = 28
Given that sin θ = 0.5, where π/2 < θ < π , find cos θ .
Answer:
cos theta is -0.866
Step-by-step explanation:
We have the range as between 90 and 180 degrees (pi is the same as 180 degrees)
The quadrant we are considering here is the 2nd quadrant
Mathematically;
if sin theta = 0.5
theta = arc•sin 0.5
theta = 30 degrees
The angle on the second quadrant is of the likes;
180-theta
so we have 180-30
and that is 150 degrees
cos (150) is thus; -0.866

Caleb bought groceries for $68.48, including sales tax. If sales tax was 7%, how much was the groceries before tax?
pls help me
Answer:
$64.00
Step-by-step explanation:
Let the amount for the groceries before tax be Y
If the cost inclusive of tax at 7% is $68.48, then
Y + 7% * Y = $68.48
100%Y + 7%Y = $68.48
107%Y = $68.48
Recall that 107% = 1.07
1.07Y = $68.48,
Divide both sides by 1.07
Y = $68.48/1.07
Y = $64.00
Hence the cost of the groceries before tax is $64

June rolls a fair dice 234 times.
How many times would June expect to roll a one?
Answer: 39 times
Step-by-step explanation: A fair dice has 6 sides with each side having a different number between 1 and 6. Therefore, the probability of rolling a 1 is 1/6. To find out how many times June would expect to roll a 1 after rolling the dice 234 times, you must multiply 234 by 1/6 to get the answer of 39.

Calculate the correct answer.
17x - 3 = 48
Answer: x = 3
Step-by-step explanation:
Simplifying
17x + -3 = 48
Reorder the terms:
-3 + 17x = 48
Solving
-3 + 17x = 48
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '3' to each side of the equation.
-3 + 3 + 17x = 48 + 3
Combine like terms: -3 + 3 = 0
0 + 17x = 48 + 3
17x = 48 + 3
Combine like terms: 48 + 3 = 51
17x = 51
Divide each side by '17'.
x = 3
Simplifying
x = 3

Isabella has already baked 4 pies, and she can bake 2 pies with each additional cup of sugar she buys. Write an equation that shows the relationship between the additional cups of sugar x and the number of pies y.
Answer:
It would be y = 2x+4
Step-by-step explanation:
This is because Isabella has started with 4 baked pies and is gaining additional pies with in amounts of 2 pies.
With this, 4 would be by itself and 2 would be attached to the variable x for the unknown amount of additional pies.
Lastly, you would have this all equaling y, as y is the total amount of pies.

Han has to build the figure below, which will serve as a counterweight, for his robotics project. Find the VOLUME of the finished object assuming it is empty inside.
Given:
A figure of a robotics project.
To find:
The volume of the finished object assuming it is empty inside.
Solution:
The given figure contains a triangular prism and a cuboid.
The dimensions of the cuboid are 6 cm, 8 cm and 5 cm. So, the volume of the cuboid is:
[tex]V_1=length\times width\times height[/tex]
[tex]V_1=6\times 8\times 5[/tex]
[tex]V_1=240[/tex]
So, the volume of the cuboid is 240 cubic cm.
The area of a triangle is:
[tex]Area=\dfrac{1}{2}\times base\times height[/tex]
So, the area of the base of the triangular prism whose base is 8 cm and height 4 cm, is:
[tex]B=\dfrac{1}{2}\times 8\times 4[/tex]
[tex]B=16[/tex]
The volume of a triangular prism is:
[tex]V_2=Bh[/tex]
Where, B is the base area and h is the height of the prism.
The base area of the triangular prism is 16 square cm and the height is 5 cm. So, the volume of a triangular prism is:
[tex]V_2=16(5)[/tex]
[tex]V_2=80[/tex]
Now, the volume of the given figure is:
[tex]V=V_1+V_2[/tex]
[tex]V=240+80[/tex]
[tex]V=320[/tex]
Therefore, the volume of the finished object is 320 cubic cm.
