If y is directly proportional to Vx, and y = 25 when x = 3, find x when
y = 100
Answers
9514 1404 393
Answer:
x = 48
Step-by-step explanation:
It looks like your proportion is ...
y = k√x
Then k can be found as ...
k = y/√x = 25/√3
__
For y = 100, the value of x can be found from ...
100 = (25/√3)√x
4√3 = √x . . . . . . . . . . multiply by √3/25
48 = x . . . . . . . . . . . . . square both sides
A motorist drives 146km at a certain speed. She then increase this speed of by 19km/hr and take the same time to travel the next 16km. Find her speed for both part of the journey. Pleaseeeeeeeeeeee helpppppppppppp
Answers
Step-by-step explanation:
A motorist drives 146km at a certain average speed she then increases the speed by 9km/h and takes the same time to travel the next 164km.
find her speeds for both parts of the journey.
:
let s = his original speed
then
(s+9) = the increased speed
:
Write a time equation; time = dist/speed
146%2Fs = 164%2F%28%28s%2B9%29%29
cross multiply
164s = 146(s+9)
164s = 146s + 1314
164s - 146s = 1314
18s = 1314
s = 1314/18
s = 73 km/h is his original speed

Answers
a^2 + b^2 = c^2
a and b are the sides next to the right angle, and c is the hypotenuse (side not connected to right angle).
You first need to find the length of the dotted line before finding x. This is because to be able to use the above formula, you have to know the length of two out of three of the sides.
To solve the length of the dotted line, note that it also makes a triangle with the 5 unit line and the 5 √5 unit line. You can plug these numbers into the formula.
(5)^2+b^2=(5 √5)^2
25+b^2=125
b^2=100
b=10
Now that you know the length of the dotted line is 10 units, you can now solve for x
(20)^2+(10)^2=x^2
400+100=x^2
500=x^2
x= √500, which equals 22.361
Which property is shown In the matrix addition above?
A. Inverse Property
B. Identity Property
C. Commutative Property
D. Associative Property
Answers
Answer :
Identity Property.
Step-by-step explanation:
Two matices are given to us , which are ,
Let A = [tex]\left[\begin{array}{ccc} 6 & -8 & 1 \\ 0 & -2 & -19 \end{array} \right] [/tex] .
Let B = [tex]\left[\begin{array}{ccc} 0 & 0& 0 \\ 0 & 0 & 0 \end{array} \right] [/tex] .
Here since all the elements of Matrix B are 0 , its a null matrix . Hence adding any matrix to it will give the same matrix which is added . This property is called as Identity Property .
Adding both A and B ,
[tex]\implies A + B = \left[\begin{array}{ccc} 6 & -8 & 1 \\ 0 & -2 & -19 \end{array} \right] + \left[\begin{array}{ccc} 0 & 0& 0 \\ 0 & 0 & 0 \end{array} \right] [/tex]
[tex]\implies A + B = \left[ \begin{array}{ccc} ( 6+0) & (-8+0) & (1+0) \\ (0+0) & (-2+0) & (-19 + 0 ) \end{array}\right] [/tex]
[tex]\red{\implies A + B = \left[\begin{array}{ccc} 6 & -8 & 1 \\ 0 & -2 & -19 \end{array} \right] }[/tex]

The quantity of rice needed for 10 people if, A recipe uses 350 grams of rice, The recipe serves 4 people, is 875 grams.
What is division?The division is the basic arithmetic operation, in which you are separating the number into some parts.
Given:
A recipe uses 350 grams of rice, The recipe serves 4 people,
Calculate the quantity of rice for serving one person as shown below,
The quantity of rice for one people = Total quantity of rice / total number of people
The quantity of rice for one people = 350 / 4
Calculate the quantity of rice for 10 people as shown below,
The quantity of rice for 10 people = 350 / 4 × 10
The quantity of rice for 10 people = 3500 / 4
The quantity of rice for 10 people = 875
Thus, the quantity of rice needed for 10 people is 875 grams.

Kenny buys a new drill for $129.90 plus 9.5% sales tax. How much does Kenny pay in total?Round the answer to the nearest cent.
Answers
Answer:
Kenny pays $142.24 in total.
Step-by-step explanation:
In order to find the total amount that Kenny pays, you have to calculate the 9.5% of the price of the drill as this is the sales tax and then, you have to add that amount to the price:
$129.90*9.5%=$12.34
$129.90+$12.34=$142.24
According to this, the answer is that Kenny pays $142.24 in total.

Raul is cutting boards for a project. He has a board that measures 8 feet and is cutting it into 3/4 foot pieces. How many whole pieces of 3/4 foot will he be able to cut?
Answers
Answer:
10
Step-by-step explanation:
1 board = 3/4 foot = 0.75 of a foot
x boards = 8 feet
1/x = 0.75 / 8 feet Cross multiply
0.75 x = 8 Divide both sides by 0.75
x = 8/0.75
x = 10 2/3 boards.
We are told to throw the fractional board away so Raul will get 10 pieces from an 8 foot piece of lumber.

Answers
Answer:
xy-3x=40, x=5
x(y-3)=40
y-3=(40/x)
y=(40/x)+3
y=(40/5)+3
y=8+3
y=11
If the variables x and y vary inversely then when x=-3 and y =-8
What is Equation?Two or more expressions with an Equal sign is called as Equation.
Since x and y vary inversely, we can write the equation:
x y = k, where k is a constant of variation.
Using the given values, we can find k:
(-4)(-6) = k
k = 24
So the equation relating x and y is:
x y = 24
To find y when x = -3, we substitute x = -3 into the equation and solve for y:
(-3) y = 24
y = -8
Therefore, when x = -3, y = -8.
