Answer:

-3/2

Step-by-step explanation:

Formula: y2 - y1/x2 - x1

1 - 4 = -3

3 - 1 = 2

Slope = -3/2

Answer:

x = 6 and y = 10

Step-by-step explanation:

If triangle ZMK is congruent to triangle APY, then;

<Z = <A

<M = <P

<K = <Y

Given the following angles

<M = 112

<Y = 41

<K = 13x - 37

<A = 2y + 7

Required

Value of x and y

Since <K = <Y, then;

13x - 37 = 41

Add 37 to both sides

13x - 37 + 37 = 41 + 37

13x = 78

x = 78/13

x = 6

Also <Z + <M + <K = 180

<Z + 112+41 = 180

<Z + 153 = 180

<Z = 180-153

<Z = 27 degrees

Since <Z = <A

27 = 2y + 7

2y = 27-7

2y = 20

y = 20/2

y = 10

Hence x = 6 and y = 10

Answer:

A. 4 units

Step-by-step explanation:

Answer:

A change from 250 to 620 represents a positive change (increase) of 148%

Use the formula found below on this webpage to find the percent change by replacing the given values:

Percent change = New - Old

|Old|

× 100%

Percent change = 620 - 250

|250|

× 100% =

370

250

× 100 = 148% (increase)

Where: 250 is the old value and 620 is the new value. In this case, we have a positive change (increase) of 148 percent because the new value is greater than the old value.

Answer:

45 marbles

Step-by-step explanation:

Answer:

a. ⅛

b. ⅜

c. -⅜

Step-by-step explanation:

a. There are 8 units from 0 to -1, and also 8 units from 0 to 1.

Given that the numberline is divided I to equal segments, therefore, each segment will be of the following equal length:

¹/8 * 1 = ¹/8

Therefore, a segment = ⅛

b. Point N is 3 units from 0.

Each unit = 1 segment = ⅛

Point N would represent:

3 * ⅛ = ⅜

c. The opposite of point N, ³/8, is the same distance that would be covered to our left from 0.

-³/8 is the opposite of point N, ⅜

Answer:

p=23

Answer:

C

Step-by-step explanation:

The area of the octagon is 1395 square units option (A) 1395 square units is correct.

A polygon is a geometric figure with a finite number of sides in two dimensions. On the sides or edges of a polygon, straight-line segments are joined end to end to form a closed shape. The vertices, also known as corners, are the points where two line segments meet and form an angle.

We have:

Octagon showed in the picture:

The area of the octagon = 2(1 + √2)a²

a is the side length.

a = 17 units

The area of the octagon = 2(1 + √2)(17)²

The area of the octagon = 1395.4 ≈ 1395 square units

Thus, the area of the octagon is 1395 square units option (A) 1395 square units is correct.

Choice C: 6.23

Step-by-step explanation:

[tex]\frac{5}{100}[/tex] = [tex]\frac{x}{124.50}[/tex] -----> cross multiply

5(124.50) = 100x

622.5 = 100x

[tex]\frac{622.5}{100} = \frac{100x}{100}[/tex]

6.225 = x

6.225 rounded to the nearest hundredth is 6.23

Centroid of ΔABC = (4,2)

Step-by-step explanation:

Explanation:-

Given points are A(0,6) , B(2,0) and C(10,0)

Centroid of ΔABC

        = [tex](\frac{x_{1}+x_{2} +x_{3} }{3} ,\frac{y_{1}+y_{2} +y_{3} }{3})[/tex]  

      =    [tex](\frac{0+2+10}{3} , \frac{6+0+0}{3} )[/tex]

     = [tex](\frac{12}{3} , \frac{6}{3} )[/tex]

     = (4 , 2)

Centroid of ΔABC = (4,2)

Answer:

The corresponding set of values of the dependent set is: {-5, -7, 0}

Step-by-step explanation:

Dependent variable and independent variable:

Suppose we have a function f(x).

The independent variable is the input value of the function, that is, x.

The dependent variable is the output value of the function, that is, f(x).

The replacement set for the independent variable is (-1, -2, 1,5).

The values of the dependent set are respectively, f(-1), f(-2) and f(1.5). So

We have that: [tex]f(x) = 2x - 3[/tex]. So

[tex]f(-1) = 2(-1) - 3 = -2 -3 = -5[/tex]

[tex]f(-2) = 2(-2) - 3 = -4 -3 = -7[/tex]

[tex]f(1.5) = 2(1.5) - 3 = 3 -3 = 0[/tex]

The corresponding set of values of the dependent set is: {-5, -7, 0}

Answer:

Force      F = 60 ×10⁻⁵ N

Step-by-step explanation:

Given that mass of the given object (m)  = 30 grams

Given that the acceleration

                                 a = 2 m/s²

Force:-

The push or pull on an object with mass that causes it to change its velocity

Formula for force

The formula for force    F = m a

                                      F = 30 × 2

                                     F  = 60 gm/s²

                                   F = 60 ×10⁻⁵ N     (∵ 1 d y n = 1gm² = 10⁻⁵N

ANSWER: 18

Step-by-step explanation:

6÷1/3=18

The number of servings she will have is 18.

Division is one of the operation in mathematics where number is divided  into equal parts as that of a definite number.

Given that,

Total quantity of the milk = 6 pint

This have to be divided in to 1/3 pint servings.

Let x be the number of servings.

We can write the equation as,

1/3 x = 6

Multiplying both sides by 3,

1/3 × 3x = 6 × 3

x = 18

Hence the total number of servings is 18.
