Answer:

60

Step-by-step explanation:

3×20 is 60, and it works with 5, and it is the smallest possible Multiple

Answer:

60

Step-by-step explanation:

Find the prime factorization of each number:

3 = 3

5 = 5

20 = 2^2 * 5

LCM = product of common factors with greatest exponent and non-common factors.

LCM = 3 * 5 * 2^2 = 15 * 4 = 60

Answer:

x = 29

Step-by-step explanation:

The two labeled angles are same-side interior angles of parallel lines cut by a transversal. They are supplementary, so their measures have a sum of 180 deg.

2x - 10 + 4x + 16 = 180

6x + 6 = 180

6x = 174

x = 29

Answer:

Step-by-step explanation:

if x = 14

2 ( x − 3 ) = 22

2 (14 - 3) = 22

2 (11) = 22

22 = 22

therefore, the answer is C.

-48x7y3

Step-by-step explanation:

The next answer on edge is also C. 9a8 + 24a4 + 16

The multiplication of -8x⁵y² and 6x²y will be -48x⁷y³ so option (C) will be correct.

Multiplication gives us a resultant number that will be very big as compared to the number which is going to be multiplied if and only if the number which is going to be multiplied is more than one.

Given the two terms,

-8x⁵y² and 6x²y

If we multiply

-8x⁵y² ×  6x²y = (-8)×6 × x⁵y² × x²y

⇒ - 48 × x⁵x² y²y¹

⇒ - 48 × x⁵⁺²y²⁺¹

⇒ - 48x⁷y³

Hence "The multiplication of -8x⁵y² and 6x²y will be -48x⁷y³".

Answer:

The coordinates of C are (8,2)

Step-by-step explanation:

We are given the segment from A(-4,-7) to B(12,5) and it's required to find a point C(x,y) that is located at 3/4 of the distance from A to B.

This means that:

[tex]d_{AC}=3/4\cdot d_{AB}[/tex]

where dAC is the distance from A to C and dAB is the distance from A to B.

The same proportion of the distances is satisfied by the coordinates of the point C, that is:

[tex]\displaystyle x-x_A=\frac{3}{4}(x_B-x_A)[/tex]

Adding xA:

[tex]\displaystyle x=\frac{3}{4}(x_B-x_A)+x_A[/tex]

[tex]\displaystyle x=\frac{3x_B+x_A}{4}[/tex]

Similarily:

[tex]\displaystyle y=\frac{3y_B+y_A}{4}[/tex]

Calculating:

[tex]\displaystyle x=\frac{3(12)-4}{4}[/tex]

x = 8

[tex]\displaystyle y=\frac{3(5)-7}{4}[/tex]

y = 2

The coordinates of C are (8,2)

Given:

The equation is

[tex]1.5x+4.5y=18[/tex]

To find:

The y-intercept (in ordered pair).

Solution:

We have,

[tex]1.5x+4.5y=18[/tex]

Putting x=0, we get

[tex]1.5(0)+4.5y=18[/tex]

[tex]0+4.5y=18[/tex]

[tex]4.5y=18[/tex]

Divide both sides by 4.5.

[tex]y=\dfrac{18}{4.5}[/tex]

[tex]y=4[/tex]

So, y-intercept is 4.

Therefore, the graph intersect the y-axis at (0,4).

You would divide it by pie r squared to get h then flip the equation around so it would be

h= v/ pie r squared

Answer:

Explanation

V = π r^2 H

V = π × r × r × H

V/ π r^2 = H

H = V/π r^2

The integer that represents the difference in high temperature from Monday to Tuesday is 38.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

The high temperature on Monday was -14 degrees.

On Tuesday the high temperature was 24 degrees.

The temperature difference between Monday and Tuesday.

= Temperature on Tuesday - Temperature on Monday

= 24 - (-14)

= 24 + 14

= 38

Thus,

The integer that represents the difference in high temperature from Monday to Tuesday is 38.

The solution to the quadratic equation (x+2)2=a if one of the solution is 1 is 9

Given the quadratic equation

(x+2)^2=a

If one of the solution is 1, then x = 1

substitute

(1 + 2)^2 = a

3^2 = a

a = 9

Hence the solution to the quadratic equation (x+2)2=a if one of the solution is 1 is 9

Answer:

Roman civilization lasted for 985 years.

Step-by-step explanation:

Given that Roman civilization began in 509 BC and ended in 476 A.

All we have to do is to subtract -579 from 476.

i.e.

[tex]476 - (-509)[/tex]

[tex]=476+509[/tex]

[tex]=985[/tex] years

Thus, Roman civilization lasted for 985 years.

Answer: length=27, width 9

Step-by-step explanation: To solve this problem, you should set up an equation. The length is 3x, and the width is x. To find the perimeter of a triangle, you do length times two + width times two. So 6x+2x=72. 8x=72, x=9. Length is 27, width is 9.

Answer:

Length: 27cm

Width: 9cm

Step-by-step explanation:

Since the length of the rectangle is 3 times the width, we can assume the    width=x and the length=3x.

      P=72cm

     Perimeter= 3x+3x+x+x

Set the 2 equations equal to each other

   72=3x+3x+x+x

Solve for x

   72=8x

   9=x

Length=3x

   Length=9(3)

   Length=27

Width=x

   Width=9

Step-by-step explanation:

The median is always the letter in the middle

Given :

On the first day of ticket sales the school sold 10 senior tickets and 1 child ticket for a total of $85 .

The school took in $75 on the second day by selling 5 senior citizens tickets and 7 child tickets.

To Find :

The price of a senior ticket and the price of a child ticket.

Solution :

Let, price of senior ticket and child ticket is x and y respectively.

Mathematical equation of condition 1 :

10x + y = 85    ...1)

Mathematical equation of condition 2 :

5x + 7y = 75    ...2)

Solving equation 1 and 2, we get :

2(2) - (1)   :

2( 5x + 7y - 75 ) - ( 10x +y - 85 ) = 0

10x + 14y - 150 - 10x - y + 85 = 0

13y = 65

y = 5

10x - 5 = 85

x = 8

Therefore, price of a senior ticket and the price of a child ticket $8 and $5.

Hence, this is the required solution.

Answer:

the point where the line on the graph meets the y-axis

Answer:

What is an y-intercept ?

A y-intercept is in analytic geometry, using the common convention that the horizontal axis represents a variable x and the vertical axis represents a variable y, a y-intercept or vertical intercept is a point where the graph of a function or relation intersects the y-axis of the coordinate system. As such, these points satisfy x= 0.

Step-by-step explanation:

I think the answer is a.

Step 1: We must determine the equation of the line in slope-intercept form* by solving for b.

[tex]-4 = -4(1) + b\\\\-4 = -4 + b\\\\0 = b[/tex]

Step 2: Now we write the equation in slope-intercept form.

[tex]y = -4x[/tex]

Step 3: We can now change the above equation to standard form by moving variables to one side.

[tex]y = -4x\\\\4x + y = 0[/tex]

Our answer is D. 4x + y = 0.

*Slope-intercept form: y = mx + b.
