Answer:

See below

Step-by-step explanation:

m = k/m     sub in the values given

-4 = k / 17

k = -68

so    m = -68/n     NOTE: this can also be written as  n = -68/m

Answer:

Step-by-step explanation:

Nikki,  they wrote the problem in a format that is general

y = k/ x      for the given variables  m and n  then

m = k / n   where k is some constant ( konstant)

plug in the given numbers for m and n

-4 =k / 17

solve for k

-4 * 17 = k

-68 = k

now we have a better formula

m = -68 / n  ( this is your answer a )

now plug in -136 for m

-136 = -68 / n  

solve for n

n = -68 / -136

n = 1/2   ( this is your answer b)

Hope that helps,  can you see how I did that?

the lengths in inches of the legs XY and XZ are, 5.53 & 7.36 .

Pythagorean theorem, the well-known geometric theorem that the sum of the squares on the legs of a right triangle is equal to the square on the hypotenuse (the side opposite the right angle)—or, in familiar algebraic notation, a2 + b2 = c2.

here, we have,

in right triangle ,XYZ, the length of the hypotenuse YZ=85 and tanZ=3/4.

so, we get,

let, the sides= 3x & 4x

now, by Pythagorean theorem,

9x^2 + 16x^2 = 85

x=1.84

hence,  the lengths in inches of the legs XY and XZ are, 5.53 & 7.36 .

Answer: 70

Step-by-step explanation: BAD is 110 degrees and BDE is 180 so do 180 minus 110 and gets you 70 which is DE

Reason:

Central angle BAD is 110 degrees.

This makes angle DAE to be 180-110 = 70 degrees since the two angles are supplementary. They combine to a 180 degree straight angle.

From there, minor arc DE is also 70 degrees. This is because the central angle subtending the arc will be the same measure.

Answer:

8/21

Step-by-step explanation:

the ratio is 5:8:8 so the total is 21 and since green is 8,the fraction is 8 over the total which is 8/21

The first choice, is exponential, because there is a relatively consistent multiplicative rate of change.

An exponential function is a function whose value is a constant raised to the power of an argument

1) I have attached the figure with the data table that represents the temperature of a cup of coffee over time.

These are the data:

Time (min) ------ Temperature (°F)

0 ----------------------- 200

10 ---------------------- 180

20 --------------------- 163

30 --------------------- 146

40 ---------------------131

50 -------------------- 118

60 -------------------- 107

2) Since, the increase in time is constant, while the decrease in temperaute is not, you know that it is not linear.

3) The other two options involve exponential models.

The exponential models have a constant multiplicative rate of change, not additive. Therefore, the only feasible choice is the first one: temperature of a cup of coffee over time.

4) You can prove it:

i) Exponential models have the general form y = A [r]ˣ, where B is r is the multiplicative rate of change: any value is equal to the prior value multiplied by r:

y₁ = A [r]¹

y₂ = A[r]²

y₂ / y1 = r ← as you see this is the constant multiplicative rate of change.

ii) Test some data:

180 / 200 = 0.9

163 / 180 ≈ 0.906 ≈ 0.9

146 / 163 ≈ 0.896 ≈ 0.9

131 / 146 ≈ 0.897 ≈ 0.9

118 / 131 ≈ 0.901 ≈ 0.9

107 / 118 ≈ 0.907 ≈ 0.9

As you see all the data of the table have a relatively consistent multiplicative rate of change, which proves that the temperature follows an exponential decay; so the right choice is the first one.

Answer:

y = 108°

Step-by-step explanation:

3x - 12 and 2x + 16 are corresponding angles and are congruent , then

3x - 12 = 2x + 16 ( subtract 2x from both sides )

x - 12 = 16 ( add 12 to both sides )

x = 28

then

3x - 12 = 3(28) - 12 = 84 - 12 = 72°

y and 3x - 12 are adjacent angles and sum to 180° , that is

y + 72° = 180° ( subtract 72° from both sides )

y = 108°

Answer:

D. 2(√34 + √106)

Step-by-step explanation:

1) Find the hypotenuse of a larger triangle infused in the kite since perimeter means the boundary of a shape. To do so, we need to apply the Pythagoras Theorem.

c² = a² + b²

c² = 5² + 9²

c² = 25 + 81

c² = 106

c = √106

2) Find the hypotenuse of the a smaller triangle infused in the kite.

c² = a² + b²

c² = 3² + 5²

c² = 9 + 25

c² = 34

c = √34

3) Apply the the formula for the perimeter of a kite; 2(a + b), where a is the smaller triangle and b is the larger triangle or vice versa.

= 2(√34 + √106)

-7?

Step-by-step explanation:

I mean, is the question 20 - 27 =? Or it's something else? Lol.

20 - 27 = -7, it's very straightforward cannot write it in more detailed way. When we substract a number from another and the first one is smaller the result is a negative number. Imagine someone sells up to 3 apples, you ask him to give you 5. He gives you all 3 of his so he has 0 but you force him to go and get another 2 for you. He lost another 2, so he has less than 0 now. He has -2 apples: 3 - 5 = -2.

The percentage that the cost of 1 kg apple is more than 1 kg of orange is 100%.

5o + 3a = 1100 equation 1

2.4o + 3.15a = 870 equation 2

Where:

Multiply equation 1 by 1.05

5.25o + 3.05a = 1155 equation 3

Subtract equation 3 from equation 2

285 = 2.85a

a = $100

Substitute for o in equation 1

5(100) + 3a = 1100

500 + 3a = 1100

3a = 1100 - 500

3a = 600

a = $200

($200 / 100) - 1 = 100%

Step-by-step explanation:

Using the concepts of the mean and of the median, it is found that the correct option is given by:

both in the interval 6–10.

To calculate the mean from the histogram, we take the midpoint of each interval and calculate the weighed mean, hence:

[tex]M = \frac{14(3) + 9(8) + 5(13) + 2(18)}{30} = 7.17[/tex]

The median is in the interval in which the 30/2 = 15th measure is, which is also in the interval 6-10, as the interval 1-5 had 14 adults, and after interval 6-10, there are 23 adults.

Hence, the correct option is given by:

When finding surface area, multiply two times pi times the radius times the height.

[tex]A = 2\pi rh+2\pi r^2[/tex]

Now, you need to split these four values into an actual equation.

2 followed by pi radius-height plus two pi radius, is actually the formula for surface added to the formula of area, so;

[tex]2\pi rh+2\pi r^2 = 2 * \pi * 8(radius) * 14 + 2(height~plus~the~two) * \pi * 8^2[/tex]

Solve.

the result is 1105 according to order of operations.

Divide 1105 by pi to get the answer. Pi is 3.14... so for every 3.14..., you count that as one.

[tex]1105 / 3.14 = 351.91...[/tex] which rounds to 352
