The radius of a circle is 1 foot. What is the area of a sector bounded by a 90 degree arc?

Answer:

0. 42

Step-by-step explanation:

any number greater than 0 is significant if it's exactly 0 or less than 0 is not significant. since it's two significant figures you count the first two numbers greater than 0 which is 0.41 and we have 8 will is greater than 5 which will be rounded to 1 then rounded to 0.41 which makes it 0.42

Step-by-step explanation:

The number of Jefferson students and the number of non-Jefferson students if A student attending Jefferson pays $5, A student attending a different school pays $10 is 373 and 127 respectively.

Equation: A declaration that two expressions with variables or integers are equal. In essence, equations are questions and attempts to systematically identify the solutions to these questions have been the driving forces behind the creation of mathematics.

Given:

A student attending Jefferson pays $5,

A student attending a different school pays $10,

The total number of tickets = 500,

The total money earned = $3135,

Write the equation of the given statement as shown below,

x + y = 500

5x + 10y = 3135

Here, x is the number of Jefferson students and y is the number of non-Jefferson students,

Solve the equation by elimination method as shown below,

y = 127,

x = 500 - 127 = 373

Thus, the number of Jefferson students is 373 and the number of non-Jefferson students is 127.

Step-by-step explanation:

Answer:

Step-by-step explanation:

There are 12 inches in one foot so the equivalent ones are:

1 to 12

This shows that there are 12 inches in one foot so is equivalent.

5 to 60

5/60 = 1/12

This is equivalent because it shows that 12 inches are required to make a foot.

9 to 108

9/108 = 1/12

This is also equivalent for the same reasons as above.

Answer:

  B

Step-by-step explanation:

The given equation is in slope-intercept form:

  y = mx + b

where the slope is m = -3 and the y-intercept is b = +2.

So, the graph will have a slope of ...

  "rise"/"run" = -3 = -3/1

and will cross the y-axis at y=2.

Graphs A and B cross the y-axis in the right place, but only Graph B has a negative "rise" a x increases.

Answer:

the perimeter of the triangle is 13[tex]in^{2}[/tex]

Step-by-step explanation:

All you have to do is add up all the sides together, but first we need to find a common denominator, and it can be 12

[tex]3\frac{1}{3}[/tex] = [tex]\frac{10}{3} = \frac{40}{12}[/tex] ( i multiplied them by 4 (numerator and denominator))

[tex]4\frac{1}{6} = \frac{25}{6} = \frac{50}{12}[/tex] ( i multiplied them by 2 (numerator and denominator))

[tex]5\frac{1}{2} = \frac{11}{2} = \frac{66}{12}[/tex] ( i multiplied them by 6 (numerator and denominator))

Now that you have a common denominator for all 3 fractions, you can now add them all up

[tex]\frac{40}{12} + \frac{50}{12} + \frac{66}{12}[/tex]

Now to add, the denominator has to stay the same (12), and add up all the numerators

[tex]\frac{40}{12} + \frac{50}{12} = \frac{90}{12} + \frac{66}{12} = \frac{156}{12} = 13 (simplified)[/tex]

Answer:

The relation [tex]y^{2} - 4x = 3[/tex] does not represent y as a function of x.

Step-by-step explanation:

Consider the relation

[tex]y^{2} - 4x = 3[/tex]

[tex]y=\pm \sqrt{4x+3}[/tex]

Thus, the equation [tex]y=\pm \sqrt{4x+3}[/tex] does not represent function because there is at least one x-value with two or more values.

For example, if you look at the attached graph,

at x = 0, y = 1.73

at x = 0 , y = -1.73

It means the same input is generating two outputs; also if we draw a vertical line on the graph, the vertical line would intersect the graph more than once.

Please check the red vertical line on the graph would intersect the graph more than once.

Therefore, the relation [tex]y^{2} - 4x = 3[/tex] does not represent y as a function of x.

The required percentage that Cortney got correct on the test will be; 85.33%.

The percentage is the ratio of the composition of matter to the overall composition of matter multiplied by 100.

We have been given that Cortney got 64 out of 75 correct on a test.

We Need to determine the best estimate of the percentage Courtney got correct.

Here,

The Total question = 75

The correct question = 64

Then Percentage = 64 / 75 × 100

Percentage = 85.33%

Thus, the required percentage that Cortney got correct on the test will be; 85.33%.

The third Graph

Step-by-step explanation:

Using the vertical line test to determine whether or not a graph represents a function. If a vertical line is moved across the graph and, at any time, touches the graph at only one point, then the graph is a function. If the vertical line touches the graph at more than one point, then the graph is not a function.

Answer:

The answer is below

Step-by-step explanation:

Transformation is the movement of a point from its initial location to a new location. Types of transformation are translation, reflection, dilation and rotation.

Dilation is the enlargement or reduction of the size of a figure. If a point A(x, y) is dilated about the center of origin by a factor k, the new point is at A'(kx, ky)

If a point A(x, y) is dilated about the point (a,b) by a factor k, the new point is at A'(k(x - a) + a, k(y - b) + b)

From the image the vertex of the triangle is at (0,0), (-2, 4) and (-2, 0). If the triangle is enlarged by scale factor 1.5 using (4,4)  as the center of enlargement.. Hence the new points are:

For (0,0): (1.5(0 - 4) + 4, 1.5(0 - 4) + 4) = (-2, -2)

For (-2,4): (1.5(-2 - 4) + 4, 1.5(4 - 4) + 4) = (-5, 4)

For (-2, 0): (1.5(-2 - 4) + 4, 1.5(0 - 4) + 4) = (-5, -2)

Given:

Original price = $15.25

Tax rate = 7%

To find:

The total amount.

Solution:

We know that,

Total amount = Original price + Tax

According to the question,

Total amount = 15.25 + 7% of 15.25

[tex]\text{Total amount}=15.25+\dfrac{7}{100}\times 15.25[/tex]

[tex]\text{Total amount}=15.25+1.0675[/tex]

[tex]\text{Total amount}=16.3175[/tex]

Round to the nearest cent (two decimal places).

[tex]\text{Total amount}\approx 16.32[/tex]

Therefore, the total value is $16.32.

Step-by-step explanation:

Sum of angles in a triangle = 180°.

=> s° + (s/7 + 3)° + (s/7 - 3)° = 180°

=> 9/7 * s° = 180°

=> s° = 180° * (7/9) = 140°

Hence the value of s is 140.
