What is the measure of an angle that is the complement of angle R? R 80

Answer:

slope = - 1

Step-by-step explanation:

calculate the slope m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (0, 2) and (x₂, y₂ ) = (2, 0) ← 2 points on the line

m = [tex]\frac{0-2}{2-0}[/tex] = [tex]\frac{-2}{2}[/tex] = - 1

Answer: -4 over 0 (I think) I hope this helps a little bit

Step-by-step explanation: Finding the slope

(-14,-10) and (-14,-6)

Use your Y values and subtract them -10-(-6) or -10 + 6= -4 that will be your numerator

Use your 2 X values and subtract them -14-(-14) or -14+14=0  that will be your denominator

Slope will be  -4 over 0

28 inch

Step-by-step explanation:

half of 38 would be 19, and take away 5 from both 19. Equally each width ( top and bottom ) 14 inch and each lenght ( Left and right ) 5 inch. so x representing width would be 14 + 14= 28 inch.

Answer: 24670000000

Step-by-step explanation:

1) First, the scientific form can help you learn that each 10 in a power will increase the number its multiplying by 10.

Since we know that when multiplying a decimal number by 10, it would move the decimal once to the right. We can apply this to the equation by moving the decimal to the right 10 times.

2) Answer

  12345678910 <= This indicates the decimal moving one place

The table will be:

Number of Minutes: 0.25. 0.5. 0.75 1

Number of heartbeats: 0.6675 1.335 2 2.67

The veterinarian recorded a cat's resting heart rate to be 120 beats over a 45-second time period. The constant will be:

= 120 / 45

= 2.67

Therefore, to find the heartbeat, we have to multiply the numbers of minutes by 2.67. This is illustrated as:

= 2.67 × 0.25 = 0.6675

This illustrates the concept of multiplication.

Using an arithmetic sequence, it is found that the next amount of train cars is of 6.

For an arithmetic sequence, the difference between consecutive terms is constant, called common difference d.

The nth term of an arithmetic sequence is given by the following rule:

[tex]a_n = a_1 + (n - 1)d[/tex]

In which [tex]a_1[/tex] is the first term.

In the context of this problem, from the image, the number of train cars can be modeled by the following sequence:

(0, 2, 4, ...)

Which is an arithmetic sequence with:

Hence the next term of the sequence is given by:

4 + 2 = 6.

As 4 is the last term and 2 is the common ratio.

Step-by-step explanation:

A confidence interval is made up of the mean of your estimate plus and minus the estimate's range. This is the range of values you expect your estimate to fall within if you repeat the test, within a given level of confidence.

A 95% confidence interval gives you a 5% chance of being wrong. A 90% confidence interval gives you a 10% chance of being wrong. In comparison to a 99% confidence interval, a 95% confidence interval is smaller (for example, plus or minus 4.5 percent instead of 3.5 percent).

When constructing a confidence interval for a propotion, if the condition of proportion requires 10 individuals in each category is not met, then confidence interval should be adjusted.

The number of individuals in each category is increased by 2 and sample size increases by 4.

The value of variable x and y are 24 and 19 respectively.

We have to find the variables x and y of the angles.

Therefore,

using angles in a triangle,

2x + 13 + 47 + 5y - 23 = 180

2x + 5y = 180 - 13 - 47 + 23

2x + 5y = 143

Using corresponding angles,

180 - (2x + 13) = 47 + 3x

180 - 2x  - 13 = 47 + 3x

180 - 47 - 13 = 3x + 2x

120 = 5x

x = 120 / 5

x = 24

Hence,

2(24) + 5y = 143

5y = 143 - 48

5y = 95

y = 95 / 5

y = 19

Answer:

<XMN = 122°

Step-by-step explanation:

An angle around a point is 360°

If LMN = 145° then the rest would be 360 - 145

360 - 145 = 215

4x + 5 + 6x - 10 = 215

Simplify = 10x - 5 = 215

work out = 215 + 5 = 220 ÷ 10 = 22

x = 22

XMN = 6x - 10

6 × 22 = 132

132 - 10 = 122

XMN = 122

======================================================

Work Shown:

As you mentioned, we'll use Pythagoras' Theorem aka Pythagorean Theorem.

[tex]a^2+b^2 = c^2\\\\(x+3)^2+(4(x+2))^2 = 25^2\\\\(x+3)^2+16(x+2)^2 = 625\\\\(x^2+6x+9)+16(x^2+4x+4) = 625\\\\x^2+6x+9+16x^2+64x+64 = 625\\\\17x^2+70x+73 = 625\\\\17x^2+70x+73-625 = 0\\\\17x^2+70x-552 = 0\\\\[/tex]

Next, we'll use the quadratic formula with a = 17, b = 70, c = -552.

[tex]x = \frac{-b\pm\sqrt{b^2-4ac}}{2a}\\\\x = \frac{-70\pm\sqrt{(70)^2-4(17)(-552)}}{2(17)}\\\\x = \frac{-70\pm\sqrt{42436}}{34}\\\\x = \frac{-70\pm206}{34}\\\\x = \frac{-70+206}{34} \ \text{ or } \ x = \frac{-70-206}{34}\\\\x = \frac{136}{34} \ \text{ or } \ x = \frac{-276}{34}\\\\x = 4 \ \text{ or } \ x \approx -8.1176\\\\[/tex]

Ignore the negative x value solution. The sides (x+3) and 4(x+2) will be negative values if we plugged in x = -8.1176, but negative side lengths do not make sense.

This makes x = 4 the only possible solution.

If x = 4, then,
