Answer:
0.22
Step-by-step explanation:
The numbers that would be greater than 78 would include numbers after 78. that is 79, 80 ... 100
The total numbers greater than 78 is 22.
And there are 100 numbers in the bag . the probability of picking a number greater than 78 is 22/100 = 0.22

-2x + 4 = 12
Explain what mistake did he make
Answer:
X=-4
Step-by-step explanation:
-2x + 4 = 12
so what you would do is subtract 4 from itself and 12
4 - 4 = 0
12 - 4 = 8
then we have-
-2x = 8
we then divide 2 from 2 and 8
2 divided by 2 = 0
2 divided by 8 = 4
so x = -4

A Cylinder has a radius of 10 feet and a height of 11.4 feet what is the approximate volume of the cylinder?
Answer:
3579.6 [tex]ft^{3}[/tex]
Step-by-step explanation:
First, write out the equation used to find the volume of a cylinder and place the values in place of the variables. The equation is [tex]\pi[/tex][tex]r^{2}[/tex]*h where r is the radius and h is the height. When we place the values of the variables into the equation we get: [tex]\pi[/tex][tex]10^{2}[/tex]*11.4. Next, square 10 to get 100. This would give you 3.14*100*11.4. When you multiply this together you get 314 times 11.4 which gives you 3579.6 ft cubed.
I believe it's 3581.42 (if the answer needs be rounded to 2 decimal places.
Step-by-step explanation:
area of circle = r×r×π
area of circle × height = volume
10 × 10 × π = 314.16
314.16 × 11.4 = 3581.42

Okay I put -646/15 but it’s wrong can someone help me
Answer:
-30 5/6
Step-by-step explanation:
You are adding two negative numbers, so add their absolute values and make the answer negative.
-28 1/3 + (-2 1/2) =
= -(28 1/3 + 2 1/2)
We add the absolute values 28 1/3 and 2 1/2. We need a common denominator for the fractions. The LCD of 2 and 3 is 6.
= -(28 + 2 + 1/3 + 1/2)
= -(30 + 2/6 + 3/5)
= -(30 5/6)
= -30 5/6

Here's a quick review of the two theorems mentioned in this worksheet:
Side-Side-Side Theorem: in reference to congruency, this theorem states that if the three sides of one triangle are equal to the respective sides of another triangle, then the two triangles are congruent.What about SAS? The letters are ordered in that way for a reason: the Side-Angle-Side Theorem tells us that if we have two triangles, and a set of two corresponding sides and their included angle are equal, then the triangles are congruent.By included angle, we mean the angle between two sides.I know, jaelee04, I'm sorry, this explanation is a bit short, but email me and I'll send you my full answer.

The measure of arc AC from the given circle is 55 degree. Therefore, option C is the correct answer.
What is relation between angle at the center and the angle at the circumference?The angle subtended by an arc at the center is twice the angle subtended at the circumference. More simply, the angle at the center is double the angle at the circumference.
Given that, in the circle, diameter AB is parallel to chord CD.
Here, measure of arc CD is 70°.
Since, AB is diameter, than the measure of arc AB is 180°.
Now, 180°-70°=110°
So, measure of arc AC = measure of arc CD = 110°/2
= 55°
Therefore, option C is the correct answer.

Lucy went to the pet store to buy 17 fish for her aquarium. She bought Fancy Goldfish for $13.49 each and Plecos for $3.25 each. She spent a total of $198.61. How many of each kind of fish did Lucy buy?
Answer:
I would say that Lucy bought at least 14 fancy goldfish and 3 Plecos.
Step-by-step explanation:
First, I subtracted 13.49 from 198.61 14 times and got 9.75. Then, I subtracted 3.25 from 9.75. It took me a while but it was worth it because I was helping a local student.

Solve algebraically the simultaneous equations
x^2+y^2=25
y-3x=13
Answer:
In the form of (x,y) there are 2 solutions:
(-3,4)
(-24/5, -7/5)
Step-by-step explanation:
First isolate one of the letters (for me I'm using the y of equation 2 because it's easier to solve)
[tex]y-3x=13\\y=13+3x[/tex]
Now that we have y isolated, substitute y in equation 1 with the equation we got previously (y=13+3x)
[tex]x^2+(13+3x)^2=25[/tex]
Now simplify:
[tex]x^2+(13+3x)^2=25\\x^2+9x^2+78x+169=25\\10x^2+78x+169=25[/tex]
Now turn the equation into ax^2+bx+c=0 form by transferring 25 to the other side of the equation:
[tex]10x^2+78x+169=25\\10x^2+78x+169-25=0\\10x^2+78x+144=0[/tex]
Using the quadratic formula we will have the 2 following values:
[tex]x=-3[/tex]
[tex]x=-\frac{24}{5}[/tex]
Substitute the following values into any equation you want (this time I'll pick equation 2 again since its the easiest to solve)
[tex]y-3x=13\\y-3(-3)=13\\y-(-9)=13\\y+9=13\\y=13-9\\y=4[/tex]
[tex]y-3x=13\\y-3(-\frac{24}{5})=13\\y-(-\frac{72}{5})=13\\y+\frac{72}{5}=13\\y=13-\frac{72}{5}\\y=-\frac{7}{5}[/tex]

Students drop a 2 kg object from rest out a window that has a
height of 10 m during a lab experiment. The students time the
object to hit the ground and measure 1.2 s. Calculate the
difference between the PE at the top and the KE at the bottom.
a. greater than 75 J
b. less than 25 J
c. between 25 J & 50 J
d. between 50 J & 75 J
Answer:
a. greater than 75 J
Step-by-step explanation:
Potential Energy at the top = mgh
Mass m = 2kg
g = 9.8m/s^2
height h = 10m
Potential Energy at the top = 2 * 10 * 9.8
Potential Energy at the top = 196Joules
The object is not moving at the bottom, hence the KE of the body at the bottom is 0Joules
difference between the PE at the top and the KE at the bottom = 196 - 0 = 196Joules
Hence the difference between the PE at the top and the KE at the bottom is greater than 75Joules

Verbal contracts are discouraged generally, because: b. without a physical signature, they can be very difficult to enforce.
What is a Verbal Contract?A verbal contract, which can also be referred to as a parol contract, is a verbal agreement reached between two parties without any form of written documentation.
A verbal contract is an agreement that comprises most of the elements contained in a normal contract and can be legally binding, however, it is without any signature which makes verbal contracts difficult to keep as any of the party involved can deny consenting to any of the agreed terms.
Therefore, verbal contracts are discouraged generally, because: b. without a physical signature, they can be very difficult to enforce.
