Answer:

8

Step-by-step explanation:

x = nickles

y = dimes

0.05x + 0.10y = 1.70

x + y = 21

y = 21 - x

0.05x + 0.10 (21 - x) = 1.70

0.05x - 0.10x + 2.10 = 1.70

-0.05x + 2.10 = 1.70

-0.05x = -0.40

x = 8

Step-by-step explanation:

To get ABCDE to A'B'C'D'E', you need to reflect the shape across line M. Then to go from A'B'C'D'E' to A''B''C''D''E'', you need to rotate about point C 180⁰.

It was first reflected across the x axis which would be line m. And since point c is the same place for the two bottom images , after the reflection it was rotated on point c.

The answer should be the 4th choice

The height of the triangle is 4 cm if the a = 6 cm and b = 5 cm and applying Pythagoras theorem.

The square of the hypotenuse in a right-angled triangle is equal to the sum of the squares of the other two sides.

The question is incomplete.

The complete question is in the picture, please refer to the attached picture.

We can draw a right angle triangle to find the hieght of the triangle.

Applying Pythagoras theorem.

Let h be the height:

b² = (a/2)² + h²

5² = (6/2)² + h²

5² = (3)² + h²

h = 4 cm

Thus, the height of the triangle is 4 cm if the a = 6 cm and b = 5 cm and applying Pythagoras theorem.

Answer:

A.

Step-by-step explanation:

The Y-intercept is 3 so C and D are automatically are wrong because their Y intercept is 2.

The slope is 2x because you count the points that the line goes through.

For example: From (-1,1) count up and right until you get another point,

count using [tex]\frac{Rise}{Run}[/tex] the rise of this equation is 2 and the run is 1 so [tex]\frac{2}{1} = 2\\[/tex]

Rise = Vertical

Run = Horizontal

Because the slope is increasing the slope is positive meaning B is incorrect because it's slope is negative.

Hope this was clear and helped you out!

The equation that matches the graph is y = -2x + 3

A linear equation is in the form:

y = mx + b;

where y, x are variables, m is the slope of the line and b is the y intercept

The line passes through the point (0, 3) and (-1.5, 0). Hence:

[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1} (x-x_1)\\\\y-3=\frac{0-3}{1.5-0} (x-0)\\\\y=-2x+3[/tex]

The equation that matches the graph is y = -2x + 3

Answer:

p = 50

Step-by-step explanation:

[tex]\frac{1}{2} *p+75=100\\[/tex]

Combine like terms into a single fraction:

[tex]\frac{1}{2} p+75=100[/tex]

[tex]\frac{1p}{2} +75=100[/tex]

Multiply by 1:

[tex]\frac{1p}{2}+75=100[/tex]

[tex]\frac{p}{2} +75=100[/tex]

Subtract 75 from both sides of the equation:

[tex]\frac{p}{2} +75=100[/tex]

[tex]\frac{p}{2} +75-75=100-75[/tex]

Simplify:

Subtract the numbers:

[tex]\frac{p}{2} +75-75=100-75[/tex]

[tex]\frac{p}{2} =100-75[/tex]

Subtract the numbers:

[tex]\frac{p}{2} =100-75[/tex]

[tex]\frac{p}{2} =25[/tex]

Multiply all terms by the same value to eliminate fraction denominators:

[tex]\frac{p}{2} =25[/tex]

[tex]2*\frac{p}{2} =2*25[/tex]

Simplify:

[tex]2*\frac{p}{2} =2*25[/tex]

[tex]p=2*25[/tex]

Multiply the numbers:

[tex]p=2*25[/tex]

[tex]p=50[/tex]

Answer:

The mean is 47

Step-by-step explanation:

First, you want to add up all of the numbers.

47 + 25 + 43 + 33 = 148

Now, you want to divide what you got by how many numbers there are.

148/4 = 37

The mean is 47

   Mean of the terms given in the data set as {47, 25, 43, 33} (four terms) will be 37.

          Mean = [tex]\frac{\text{Total of the terms in a data set}}{\text{Numbers of the terms}}[/tex]

Total of the terms given in the the data set = 47 + 25 + 43 + 33

                                                                        = 148

Number of terms in the data set = 4

Substitute these values in the expression of the mean,

Mean = [tex]\frac{148}{4}[/tex]

          = 37

      Therefore, mean of the data set given in the question is 37.
