Find Sin A
Help please

Step-by-step explanation:

common ratio r = 98/140

first term a = 140

geometric sequence formula is an = ar^(n-1)

an = 98^(n-1)

where n is the number of terms in the sequence

Answer:

[tex]\frac{6.3cm}{18cm}=0.35[/tex]

or 35%

cos(70°)=0.34

The difference in the result is because of the precision of the measurements.

Step-by-step explanation:

First, we can start by drawing a horizontal line in our sheet of paper and pick one point on the line. (Picture 1)

Next we take our protractor and measure 70°. (Picture 2)

Then we draw a line that measures 18cm with our ruler from the point we selected on the horizontal line to the point we measured with the protractor. (Picture 3)

Next we take our square and measure a 90° angle from the end of the line we drew on the previous step to the horizontal line and connect the horizontal line to the ending point of the hypotenuse. (Picture 4)

And that will be our triangle. Next we can measure the adjascent side to the 70° angle (Picture 6) which turned out to be 6.3cm which can now be used to calculate the ratio as a percentage. (Picture 5)

[tex]ratio=\frac{adjascent}{hypotenuse}=\frac{6.3cm}{18cm}=0.35[/tex]

which is the same as a 35%.

If we calculated the cos(70°) with our calculator we would get:

cos(70°)=0.34

As you may see our measurements were pretty precise, the difference in answers will depend on the precision of our measurements.

Answer:

6.4 cm

Step-by-step explanation:

i think you'd use pythagoras theorem if you don't know any of the angles . a^2 + b^2 = c^2 . so 4^2 + 5^2 = square root 41 ,, = 6.403124237 cm

i apologise if it is incorrect ^^

Answer:

Elimination

x = 2

y = -2

Step-by-step explanation:

Elimination

2x + 4y = -4

2x - y = 6

Subtract the second equation from the first

5y = -10

Divide both sides by 5

y = -2

---------------------

Substitute for y = -2 in the second equation

2x - -2 = 6

2x + 2 = 6

subtract 2 from both sides

2x = 4

Divide both sides by 2

x = 2

ratio of sides in a 30-60-90 triangle is  1 : [tex]\sqrt{3}[/tex] : 2

Answer:

The slope of the line that passes through the points (2, 3) and (8, 6) is [tex]\frac{1}{2}[/tex].

Step-by-step explanation:

To find the slope of two points, divide the difference between the y values by the difference between x values, you can remember this by the mnenomic "rise over run". In this case, the difference between y and x values would be 6 - 3 = 3 and 8 - 2 = 6 respectively. This means the slope between the two points (2, 3) and (8, 6) is [tex]\frac{3}{6}[/tex] or [tex]\frac{1}{2}[/tex].

Answer:

The probability that his bill will be less than $50 a month or more than $150 for a single month is 0.3728 = 37.28%.

Step-by-step explanation:

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

A salesman who uses his car extensively finds that his gasoline bills average $125.32 per month with a standard deviation of $49.51.

This means that [tex]\mu = 125.32, \sigma = 49.51[/tex]

Less than 50:

p-value of Z when X = 50. So

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{50 - 125.32}{49.51}[/tex]

[tex]Z = -1.52[/tex]

[tex]Z = -1.52[/tex] has a p-value of 0.0643

More than 150

1 subtracted by the p-value of Z when X = 150. So

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{150 - 125.32}{49.51}[/tex]

[tex]Z = 0.5[/tex]

[tex]Z = 0.5[/tex] has a p-value of 0.6915

1 - 0.6915 = 0.3085

The probability that his bill will be less than $50 a month or more than $150 for a single month is:

0.0643 + 0.3085 = 0.3728

The probability that his bill will be less than $50 a month or more than $150 for a single month is 0.3728 = 37.28%.

Answer:

2x= 38.5

Step-by-step explanation:

I'm not sure where u got 12x but 2 x = 38.5:

2x + 5 =82

subtract 5 for 82

2x = 77

77 divided by 2 is 38.5

x = 38.5

hope this helps :)

Answer:

$208

Step-by-step explanation:

First, divide.

80 ÷ 5 = 16

Next, multiply.

16 × 13 = 208

Lastly, have a wonderful day! :)

Answer:

At the same rate, Latoya would make $208 for 13 hours of work.

Step-by-step explanation:

Since Latoya made $80 for 5 hours of work, that means she made a unit rate of $16 per hour. By working at the same rate for 13 hours, she would make a total of [tex]16 * 13 =[/tex] $208.

Answer:

  3.  C(−1, −5), D(2, −5)

Step-by-step explanation:

The given points are 2 -(-1) = 3 units apart horizontally, so the remaining points will need to be 18/3 = 6 units below, vertically. Translating the given points down 6 gives ...

  D = A -(0, 6) = (2, 1) -(0, 6) = (2, -5)

  C = B -(0, 6) = (-1, 1) -(0, 6) = (-1, -5)

The two points required to make a rectangle with an area of 18 square units are ...

  C(-1, -5), D(2, -5)

_____

The area of a rectangle is the product of length and width. If the area is 18 square units, and the width is 3 units, then the length must be 6 units. 3×6=18.

Answer:

120

Step-by-step explanation:

volume of triangular prism = area of base times length

the base is a triangle and the area of a triangle can be calculated by using this formula

[tex]a=\frac{bh}{2}[/tex]

where b = base length and h = height

Dimensions of base

base length = 8cm and height = 3cm

Thus,

[tex]A=\frac{3*8}{2} \\3*8=24\\\frac{24}{2} =12\\[/tex]

The length of the triangular prism is 10cm

Thus volume = 10 * 12 = 120
