Find the missing side of each triangle

Answer:

$11.28

Step-by-step explanation:

Given data

Cost of bicycle= $282

tax= 4%

let us find the sales tax

=4/100*282

=0.04*282

=$11.28

Hence the sales tax is $11.28

Answer:

136

Step-by-step explanation:

This question is poorly phrased.  However, the answer must be 0.68*200=136.

The reason is that, by definition, an X% confidence range is computed in such a way that the expected percentage of X% confidence ranges constructed over many samples that will contain the true mean is X%.

Using the interpretation of a confidence interval, it is found that 136 of the intervals would be expected to contain the population mean.

It means that we are x% confident that the population parameter(mean/proportion/standard deviation) is between a and b.

Out of n intervals, x% are expected to contain the population mean, hence:

0.68 x 200 = 136.

Answer:

Step-by-step explanation:

the volume of a sphere is

V= (4/3)*3.14*r^3

89,110=4/3 * 3.14* r^3

89110/3.14=4/3*r^3

28,378.98=4/3*r^3

(3*28,378.98)/4=r^3

21,284.23=r^3

r=[tex]\sqrt[3]{21284.23}[/tex]=27.71

d=2*r=55.42 cm rounded is 55 cm

The diameter of the sphere is 55.4 cm where its volume is given as 89110 cm³. This is obtained by equating the volume of the given sphere with the standard formula, we get the radius and we know that twice a radius is the diameter.

The standard formula for the volume of a sphere is given as

[tex]V=\frac{4}{3}\pi r^{3}[/tex]

where r is the radius of the sphere

The diameter of a sphere is twice its radius i.e.,

d = 2r

It is given that volume of the sphere V = 89110 cm³

On substituting,

[tex]89110 = \frac{4}{3}\pi r^{3}[/tex]

⇒ [tex]r^{3}=\frac{267330}{4\pi}[/tex]

⇒ [tex]r^{3}=21273.44[/tex]

⇒ [tex]r=\sqrt[3]{21273.44}[/tex]

⇒ r = 27.708

Then,

Diameter d = 2 × r

                   = 2 × 27.708

                   = 55.41

Rounding the obtained value to the nearest tenth results in 55.4

Therefore, the diameter of the given sphere with a volume of 89110 cm³ is 55.4 cm

Answer: 9:4

Step-by-step explanation:

Number of rock songs = 10

Number of rap songs = 6

Number of pop songs = 2

Total number of songs = 18

The ratio of all songs to songs that are not rock will be:

= 18 : (6 + 2)

= 18 : 8

= 18/8 = 9/4

= 9:4

The answer is 9:4

Answer:

y= -1, x= -1

5x+6y=-11

-(5x-2y=-3)

     8y=-8

      y=-8/8

      y= -1

5x+6(-1)=-11

5x-6     = -11

        5x=-11+6

        5x=-5

          x=-5/5

          x=-1

The required solution of the simultaneous equation is x = -1 and y = -1.

Given that,
To solve the given simultaneous equation,
5x+6y= −11
5x = 2y −3

Simultaneous linear equations are two- or three-variable linear equations that can be solved together to arrive at a common solution.

here,
5x = 2y −3 - - - - - (1)
5x+6y= −11
By substitution, from equation 1
2y - 3 + 6y = -11
8y = -8
y = -1
Now,
5x = -2 - 3
x = -1

Thus, The required solution of the simultaneous equation is x = -1 and y = -1.

Answer:

[tex]\frac{2}{3}[/tex]

Step-by-step explanation:

Just simply add along the top of the numbers.

1. We know that there were 12 pieces and out of those 12 Joe ate 3 pieces and Sam ate 5.

2. So now we have the two fractions [tex]\frac{3}{12}[/tex] and [tex]\frac{5}{12}[/tex] we simply add them together by adding across the top, we do not need to make any changes to the denominator due to the fact that they are parts of the 12 pieces of pie

3. after adding 3 + 5 you should get 8 and since the denominator will remain the same the answer should be [tex]\frac{8}{12}[/tex]

4. Now we must simplify we know 8 ÷ 4 = 2 and we can also divide 12 by 4 and that gets us 3 so make the numbers into a fraction, 3 should be on the bottom, and two on the top, and when you have your final answer your work should look somewhat similar to this:

[tex]\frac{3}{12}+\frac{5}{12} =\frac{8}{12} =\frac{2}{3}[/tex]

=4

Answer:

4

Step-by-step explanation:

Since you can't divide a fraction by another fraction, you start by flipping the second fraction (-1/6 becomes -6/1) and changing the division sign to multiplication.

-2/3 x -6/1

Multiply across, numerator with numerator and denominator with denominator. Also, when multiplying or dividing negative numbers, two negatives make a positive (i.e. -2 x -6 = +12)

-2/3 x -6/1 = 12/3

12/3 = 4
