What is the missing side?
Answer:
90
Step-by-step explanation:
the forumla of a triangle is base times height, divided by 2 and since it has a height of 12 and a base of 15, and if you multiply that it would give you 180, then divide by 2 since it is half a sqaure, which is 90

Please help ASAP
Answer:
6,666.67cube units
Step-by-step explanation:
Volume of the square based pyramid = BH/3
B is the base area
H is the height of the pyramid
Base area = Length * length
B = 25 * 25
B = 625 square units
Height = 32units
Volume = 625*32/3
Volume = 6,666.67cube units

Step-by-step explanation:
Shawn is typing a paper for class. He can type 1 5/11 pages in 1/ 3 of an hour. How many pages can Shawn type in one hour?
A 1 3/11
B 1 8/11
C 4 4/11
D 5 9/11
Answer:
the amount of pages typed after 1/3 of an hour is given. Multiply this number by 3 to get the full hour of pages types.
1 5/12 * 3 = 3(1) + 3(5/12)
= 3 5/4
= 4 1/4 pages
A large emerald with a mass of 982.7 grams was recently discovered in a mine. If the density of the emerald is 2.76 grams over centimeters cubed, what is the volume? Round to the nearest hundredth when necessary and only enter numerical values, which can include a decimal point.
Answer:
356.05 cm³
Step-by-step explanation:
We are looking for the volume. The formula is density = mass / volume.
If we plug in our numbers, our formula would be 2.76 = 982.7 / V.
Multiply both sides by V and your formula would be (V) 2.76 = 982.7.
Divide both sides by 2.76 and you would get V = 356.05.
The volume of the given large emerald is required.
The volume of the given large emerald that was discovered in the mine was 356.05 cm³. The calculations to find this value is shown below.
Densitym = Mass of object = 982.7 grams
[tex]\rho[/tex] = Density of the material the object is made of = 2.76 grams over centimeters cubed
The relation between mass, volume and density is given by
[tex]V=\dfrac{m}{\rho}\\\Rightarrow V=\dfrac{982.7}{2.76}\\\Rightarrow V=356.05072\approx 356.05\ \text{cm}^3[/tex]

Find the value of x.
Put the following equation of a line into slope-intercept form, simplifying all fractions.
Answer:
y=1/2x-2
Step-by-step explanation:
2y=-4+x
2y=x-4 divide both sides by 2
y=1/2x-4/2
y=1/2x-2
Answer:
[tex]y = 0.5x - 2[/tex]
Step-by-step explanation:
Slope intercept form is
[tex]y = mx + b[/tex]
Our initial goal is to isolate y.
[tex]2y - x = -4[/tex]
Add x to both sides of the equation.
[tex](2y - x) + x = (-4) + x[/tex]
Simplify.
[tex]2y =x -4[/tex]
Divide both sides by 2.
[tex]\frac{2y }{2} = \frac{(x - 4)}2}[/tex]
Simplify.
[tex]y = 0.5x - 2[/tex]

When factoring this equation we need to find 2 numbers that multiply to get positive (15) and add to get negative (-8)
So -3 and -5 fit this description because -3+-5=-8 and -3*-5=15
(x-3)(x-5)=0
Solve for values of x to get x=3 and x=5
so X=3 or 5
A 30 foot ladder is leaning against the side of a building and is positioned such that the base of the ladder is 21 feet from the base of the building how far above the ground is the point where the ladder touches the building
Answer:

a²+b²=c² where "c" is the hypotenuse of a right triangle and "a" and "b" are the two other sides
now let's plug in the values
21²+b²=30²
b²= 30² - 21²
b²= 459

A cylinder shaped water tank has a diameter of 8 m and a height of 20 m.
What volume of water does the tank contain when it is 60% full?
Use 3.14 to approximate pi.
Enter your answer as a decimal to the hundredths place in the box.
___ m3
Answer:
602.88 cu ft.
Step-by-step explanation:
V = Bh where B is the area of the base, which is a circle in your problem.
Since the diameter is 8, the radius is 4.
So, B = [tex]\pi r^{2} = 3.14(4^{2} ) = 3.14(16) = 50.24[/tex]
V = Bh = 50.24(20) = 1004.8 cu ft = total volume of tank
60% of that volume is .60(1004.8) = 602.88 cu ft.

What type of angle relationship is shown?
Answer:
straight angle
Step-by-step explanation:
9x_15+2x_3=180
11x_18=180
11x=180+18
11x=198
x=198÷11
x=18
Answer:
The angles are a linear pair.
x = 18
Step-by-step explanation:
The angles are a linear pair, meaning the angles add up to 180 degrees.
(9x - 15) + (2x - 3) = 180
11x - 18 = 180
11x = 198
x = 18
