The diameter of a circle is 9 feet. Find the radius

Answer:

A prism is a three-dimensional solid figure with two parallel faces, called bases, that are congruent polygons, and lateral flat faces which are rectangles in a right prism, and are parallelograms in an oblique prism.

Sample response: A triangular prism has a 3-sided base and 3 lateral faces. A rectangular prism has a 4-sided base and 4 lateral faces. The number of sides of the base of a prism is equal to the number of lateral faces of the prism.

Answer:

Part 1: It is not a valid conclusion to say that track and field sports are more popular than soccer based on the survey. The survey was taken at a track and field event so the people that were surveyed are probably biased.

Part 2: A better way of determining which sport is more popular is by counting how many people show up to each event and comparing the results.  

Responder:

x = 15/7

Explicação passo a passo:

Dada a equação:

7 x + 4 = 19

Subtraia 4 de ambos os lados

7x + 4 - 4 = 19 - 4

7x = 15

Divida os dois lados por 7

7x / 7 = 15/7

x = 15/7

Step-by-step explanation:

Find the unit rate of Sugar. Then find the cost of  2.5 Kg sugar

1 kg sugar =36 ÷ 4.5

                [tex]= \frac{36*10}{4.5*10}= \frac{360}{45}\\\\= 8[/tex]

2.5 kg of sugar= 2.5 * 8 = 20.0 = R 20

Answer:

Kg Rupee

4.5 = 36

2.5 = ?

Therefore, 2.5*36/4.5

Therefore, 25*36*10/45*10

Therefore, 25*36/45

Therefore, 5*5*36/9*5

Therefore, 5*36/9

Therefore, 5*3*2*3*2/3*3

Therefore, 5*2*2

Therefore, 10*2

Therefore, 20

2.5 kg =20 Rupees

Answer:

254.34 ft^2

Step-by-step explanation:

The equation for area of a circle is π*r^2, where r is the radius of the circle. So we do 3.14*9^2 for the answer

Answer:

254.34 ft

Step-by-step explanation:

radius (9)

multiply it by itself (9x9)

so then you get 81

then the two radius squared (81) is multiplied by pi (3.14)

Answer: C. The answer i got was C

Answer: 904.32 cm^3

Step-by-step explanation:

The formula to finding the volume of a sphere is (V=4/3(3.14)r^3

So in this case it would be (V=4/3(3.14)(6)^3

The radius is half the diameter so that's how I got 6.

The answer after multiplying everything would be 904.32

Answer:

a) 2nd and 3rd quadrant

b) 143.13° and 36.87°

Step-by-step explanation:

Secant A = 1/cosecant A

sec A = 1/cosA

If Sec A = -5/4

Cos A = 1/(-5/4)

CosA  = -4/5

Since cos A is a negative values, hence the angle A will be in the 2nd and 3rd quadrant

b) If CosA  = -4/5

A = arccos(-0.8)

A = 143.13

A = 180 - 143.13

A = 36.87

Hence the measures of angle A are 143.13° and 36.87°

Answer:

See below.

Step-by-step explanation:

Adding 2 to both sides will not help solve the equation.

Adding 2 to both sides gives you this:

x^3 = ∛(x-2)

x^3 + 2 =∛(x-2) + 2

What was the original question?

Answer: 30%

Step-by-step explanation:

Given:

A line passes through the points (9,9) and [tex](x_2,-1)[/tex].

The slope of the line is [tex]\dfrac{5}{6}[/tex].

To find:

The value of [tex]x_2][/tex].

Solution:

Slope formula:

[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

The line passes through the points (9,9) and [tex](x_2,-1)[/tex]. So, the slope of the line is:

[tex]m=\dfrac{-1-9}{x_2-9}[/tex]

[tex]m=\dfrac{-10}{x_2-9}[/tex]

It is given that the slope of the line is [tex]\dfrac{5}{6}[/tex].

[tex]\dfrac{5}{6}=\dfrac{-10}{x_2-9}[/tex]

[tex]5(x_2-9)=-10(6)[/tex]

[tex]5x_2-45=-60[/tex]

[tex]5x_2=-60+45[/tex]

[tex]5x_2=-15[/tex]

Divide both sides by 5.

[tex]x_2=-\dfrac{15}{5}[/tex]

[tex]x_2=-3[/tex]

Therefore, the value of [tex]x_2[/tex] is [tex]-3[/tex].

Answer:

Y = 50 degrees, X = 60 degrees

Step-by-step explanation:

Since we know that the sum of angles in a triangle is 180 degrees, we can find x easily. We already know that the other two angles are 50 and 70, which adds up to 120, and 180 - 120 is equal to 60 degrees, meaning that x is equal to 60 degrees. Next, to find the measure of y, we first know that the sum of angles on a line is equal to 180 degrees, and if we find the other angle on the line by subtracting 60 + 50 from 180, we can find y. 180 - (60 + 50) = 70 degrees, and since 70 + x + y = 180 and x = 60, we know that x = 180 - (70 + 60) = 50. Therefore, y is equal to 50 degrees.

Answer:

The key features needed to determine if these two linear functions intersect would be their y-intercept and their slopes. We need this information because it would allow us to graph these two linear functions, and if we can graph them, we can see if these lines intersect.
