Answer:
Step-by-step explanation:
Let Justin's age be x
Arlene today is 1/4 x
Ten years from now
Arlene: 1/2 (x + 10) = 1/4 x + 10 Remove the brackets
1/2 x + 5 = 1/4x + 10 Subtract 1/4x from both sides.
1/2 x - 1/4x + 5 = 10 Combine
1/4x + 5 = 10 Subtract 5 from both side
1/4 x = 10 - 5 Combine
1/4 x = 5 Multiply both sides by 4
x = 5 * 4
x = 20

All triangles in this shape have same area as they have same base length and height length.
area of triangle: 1/2 * base * heightHere the base is 4.2 cm and height is 2.5 cm for all the given triangles.
As a result, we can say that the area of [tex]\triangle[/tex] A, [tex]\triangle[/tex] B, [tex]\triangle[/tex] C are equal.
Answer:
area A = 5.25 cm²
area B = 5.25 cm²
area C = 5.25 cm²
Step-by-step explanation:
area of a triangle = 1/2 x base x height
area of A = 1/2 x 4.2 x 2.5 = 5.25 cm²
area of B = 1/2 x 4.2 x 2.5 = 5.25 cm²
area of C = 1/2 x 4.2 x 2.5 = 5.25 cm²
Triangles A, B and C have the same area as they all have the same measures of base and height.

if x^2=36 and y^2=81 which of the following cannot be the value of x+y
A. -15
B. -3
C. 0
D. 3
E. 15
Answer: 0
Step-by-step explanation:
We can unsquare the squareroots:
x^2=36
Becomes
x=6 (because 6*6 is 36)
similarly,
y^2=81
Becomes:
y=9(because 9*9=81)
When you have a squareroot no matter if it’s negative or positive the result is a positive number.
Now we can solve and eliminate possible solutions.
For A) -9+(-6)=(-15)
For B) (-9)+6=(-3)
For D)(-6)+9=3
For E) 9+6=15

Arielle is filling up the kiddie pool for her younger sister and places a hose in the pool, allowing water to fill the pool. After a certain number of minutes, Arielle finds a second hose, places it in the kiddie pool, and allows more water to fill the pool.
Arielle can express the average rate of water entering the kiddie pool in gallons per minute as 2x+6(x+3)/2x+3.
What is the meaning of the parts of this rational expression in the context of the situation?
Select from the drop-down menus to correctly complete the statements.
The numerator of the rational expression represents the ____
The denominator of the rational expression represents the ____
Possible solutions for the fill in the blank above:
A. Total number of gallons of water in the kiddie pool.
B. Total number of minutes filling the kiddie pool.
C. Number of gallons each hose dispenses.
The given rational function that gives the average rate of water entering
the pool is the total volume in the pool divided by the time.
Response:
The numerator of the rational expression represents the;
A. Total number of gallons of water in the kiddie pool
The denominator of the rational expression represents the;
B. Total number of minutes of filling the kiddie pool
Which methods are used to determine the parts of the rational function?The given parameters are;
[tex]Expression \ for \ average \rate \ of \ water \ entering \ the \ pool = \mathbf{ \dfrac{2 \cdot x + 6 \cdot (x + 3)}{2 \cdot x + 3}}[/tex]
The parts of the given expression can be analyzed as follows;
x = The time in which the second hose is in use
2 = The flow rate of the second hose in gallons per minute
6 = The flow rate of the first hose in gallons per minute
x + 3 = The time in which the first hose is in use
x + x + 3 = 2·x + 3 = The total number of minutes of filling the kiddie pool
Therefore;
2·x = The volume added to the pool due to the second hose
6·(x + 3) = The volume added to the pool due to the first hose
2·x + 6·(x + 3) = Total number of gallons of water in the kiddie pool
Which gives;
The numerator of the rational expression represents the;
A. Total number of gallons of water in the kiddie pool
The denominator of the rational expression represents the;
B. Total number of minutes of filling the kiddie pool

James has a 6-ft board that is 24 in. wide. He wants to cut it into five pieces to make a small bookshelf with two shelves. The front and back will not be covered. What should the dimensions of the bookshelf be to maximize the volume and use all of the 6 ft board?
Answer:
width=x, length = y

3x + 2y = 6y>x
y = 1.5 , x= 1
1ft = 12 in 1.5ft = 18in
Write an Irrational number that can be added to the irrational number 5 to get a rational sum of 6.
Answer:
41 -12√5
Step-by-step explanation:
All square roots of natural numbers, other than of perfect squares, are irrational.so, let the unknown irrational number be x,
solve:
√x + √5 = 6
√x = 6 - √5
( √x ) ² = ( 6 - √5 )²
x = ( 6 - √5 )( 6 - √5 )
x = 36 -6√5 -6√5 + 5
x = 41 -12√5

teh face of a circular game token has an area of 10pi cm to the second power. what is the diameter of the coin token. round to the nearest hundredth of a centimeter
Answer:
6.32 cm
Step-by-step explanation:
Area of a circle = [tex]\pi r^2[/tex] (where r is the radius)
Given area = [tex]10\pi[/tex] cm²
⇒ [tex]10\pi=\pi r^2[/tex]
[tex]\implies 10=r^2[/tex]
[tex]\implies r=\sqrt{10}[/tex]
Diameter = 2r (where r is the radius)
[tex]\implies d=2r=2\sqrt{10}=6.32[/tex] cm (nearest hundredth)

I really really really really need help with this question
Answer:
When rotating any polygon 90 degrees, each vertice/point of the polygon should be changed from (x, y) to (y, -x). Because of this, E(-7, -4) should be E'(-4, 7), F(-2, -1) should be F'(-1, 2), and G(-5, -8) should be G'(-8, 5) after the rotation.
Step-by-step explanation:
Like I explained above, when rotating a shape 90 degrees clockwise on a plane, the points change from (x, y) to (y, -x). The student changed each point from (x, y) to (-y, x), which is a 90 degree counterclockwise rotation. That is why the student is incorrect.
