Answer:
x = 0.3333333333
Step-by-step explanation:
Simplifying
42x = 14
Solving
42x = 14
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Divide each side by '42'.
x = 0.3333333333
Simplifying
x = 0.3333333333
(5×100)+(6×110)+(7×1100)

(x + 7)^2 – 11 = 0
lesser =
greater =
Answer:
Lesser = -[tex]\sqrt{11}[/tex] - 7 = -10.317
Greater = +[tex]\sqrt{11}[/tex] - 7 = -3.683
Step-by-step explanation:
I am assuming you are asking for the lesser x solution and greater x solution.
(x + 7)^2 – 11 = 0
(x + 7)^2 = 11
x+7 = ±[tex]\sqrt{11}[/tex]
x = ±[tex]\sqrt{11}[/tex] - 7
Lesser = -[tex]\sqrt{11}[/tex] - 7 = -10.317
Greater = +[tex]\sqrt{11}[/tex] - 7 = -3.683
Answer:
lesser= -14
greater= 0 (:

14. A right cone has a height of 14 in and a base diameter of 17 in.
a Sketch and label a diagram of the cone
b. Determine the area of the lateral surface of the cone, to the nearest square inch
Given:
The height of a right cone = 14 in
Base diameter = 17 in
To find:
The diagram of the cone and its lateral surface area.
Solution:
(a)
The diagram of a right cone with height 14 in and base diameter of 17 in is shown below.
Diagram is not to scale.
(b)
We know that lateral surface of the cone is
[tex]A=\pi rl[/tex]
[tex]A=\pi r\sqrt{r^2+h^2}[/tex] ...(i)
Where, r is the base radius, h is vertical height and l is the slant height of the cone.
Base radius of the cone = [tex]\dfrac{\text{Base diameter}}{2}[/tex]
[tex]r=\dfrac{17}{2}[/tex]
[tex]r=8.5[/tex]
Now,
Putting r=8.5, h=14 and π=3.14 in (i), we get
[tex]A=(3.14)(8.5)\sqrt{(8.5)^2+(14)^2}[/tex]
[tex]A=26.69\sqrt{72.25+196}[/tex]
[tex]A=26.69\sqrt{268.25}[/tex]
[tex]A=437.1379[/tex]
[tex]A\approx 437[/tex]
Therefore, the lateral surface area of the cone is 437 sq. inches.

Two balls are picked in succession without replacement -4 white balls and 5 green balls let Y be the random representing the number of green balls. Find the value of the random variable Y.
Answer:
If Y represents the number of green balls then it can have values from 0- 5
that is it can have all the value 0,1,2,3,4 and 5.
The probability of getting both balss green without replacement is 0.27778
Step-by-step explanation:
If the balls are not replaced then this is the dependent event .
The probability of getting the first ball is given be = 5/9
where 5 is the number of green balls and 9 is the total number of balls.
The probability of getting the second ball green given that first is also green is = 5/9* 4/8= 20/72= 0.2778
If Y represents the number of green balls then it can have values from 0- 5
that is it can have all the value 0,1,2,3,4 and 5.
0 means there can be no green balls or white balls.
1 means there can be one green ball.
2 means there can be 2 green balls and so on.
In this exercise we have to use the knowledge of probability to calculate the chance of an event to occur, so you have to:
the chance of the event is 0.2778%
So organizing the information given in the statement is:
If the balls are not replaced then this is the dependent event .The probability of getting the first ball is given be = 5/95 is the number of green balls and 9 is the total number of balls.So with this information we can write that:
[tex]5/9* 4/8= 20/72= 0.2778[/tex]

What is the slope of the line that passes through the points (−6,−4) and (-12, -4) ?
Answer:
0
Step-by-step explanation:
The formula for slope is [ y2-y1/x2-x1 ].
-4-(-4)/-12-(-6)
0/-6
Since the numerator is 0, the slope is 0.
Best of Luck!

Decrease 120 by 60%
Answer:
48
Step-by-step explanation:
if increase⇒100%+the percentage given in the question
e.g ⇒ increase N (number) by 50%
so 150/100×N
if decrease⇒100% - the percentage given in the question
e.g ⇒ decrease N (number) by 70%
so 30/100×N
the answer of this question by steps is:
100%-60%=40%
40/100×120=48

A cuboid with a square base of side length 6 cm and height 10 cm then its volume equal what in Sixth grade of primary school
Answer:
360
Step-by-step explanation:
Volume of cube is s^3
Volume of a rectangular prism is BH, OR LWH
Since the base is a SQUARE, and it has a side length of 6 cm, the other side length is also 6 cm. 6 x 6 x 10 = 360 cm cubed.

You have 59 total coins in a jar on your nightstand at home. The total amount of money is $12.05. You only have quarters and dimes. How many of each type of coin do you have? (hint - use a different method to write and solve the system).
9514 1404 393
Answer:
41 quarters18 dimesStep-by-step explanation:
When there are two contributors to the mix, it usually works well to let a variable represent the quantity of the larger contributor. Here, that larger contributor is the quarter.
Let q represent the number of quarters. Then 59-q is the number of dimes. The value of the coins, in cents, is ...
25q +10(59 -q) = 1205
15q +590 = 1205 . . . . . . . . eliminate parentheses, collect terms
15q = 615 . . . . . . . . . . . subtract 590
q = 41 . . . . . . . . . . divide by 15
59-q = 59 -41 = 18 . . . . . number of dimes
You have 41 quarters and 18 dimes.
