Answer:

i think 82.00 per hour im not really sure

kong: 15% 15x100=1,500

Nolan:85 seconds 85x2=170

then when you multiple kong by 15 and 100 it gives you 1,500 however nolan did of the seconds 85x 2 gives you 170 . in conclusion Nolan did 15x2=30 . which means Nolan did 30 seconds.

Answer:

The SI unit for length is the meter (abbreviated m); its definition has also changed over time to become more accurate and precise. The meter was first defined in 1791 as 1/10,000,000 of the distance from the equator to the North Pole.

Answer:

514 m = width of the river to the nearest meter

Step-by-step explanation:

You must memorize the definitions of the trig functions and then these types of problems are easy.

You have a right triangle where the 100 m is the adjacent side to the 79° angle.  You are looking for the side opposite the 79° angle.  So, you need to use the tan function which is defined as opposite side/adjacent side

Let x = the length of the opposite side (width of river)

Tan 79 = x/100

100 tan 79 = x

x = 514 m = width of the river to the nearest meter

The tangent or tanθ in a right angle triangle is the ratio of its perpendicular to its base. The width of the river is 514.455 meters.

The tangent or tanθ in a right angle triangle is the ratio of its perpendicular to its base. it is given as,

[tex]\rm Tangent(\theta) = \dfrac{Perpendicular}{Base}[/tex]

where,

θ is the angle,

Perpendicular is the side of the triangle opposite to the angle θ,

Base is the adjacent smaller side of the angle θ.

As it is given that you walk 100 meters to the right of the stake and measure a 79° angle between the stake and the boulder. Therefore, using the tangent angle the width of the river can be written as,

[tex]\rm Tangent(\theta) = \dfrac{Perpendicular}{Base}\\\\\\\rm tan(79^o) = \dfrac{\text{Width of the river}}{100\ meter}\\\\\\\text{Width of the river} = tan(79^o) \times 100 = 514.455\ meters[/tex]

Hence, the width of the river is 514.455 meters.

Answer:

11

Step-by-step explanation:

We can buy 10 gallons of gas with $30, whose unit price is $2.85.

The rate calculated for one quantity of something is called unit rates.

Given that, the gas costs $2.85 per gallon, we need to find how many whole gallons of gas could you buy with $30.00.

Let the x gallons cost $30.00

Therefore,

2.85x = 30

x = 30 / 2.85

x = 10.52

x ≈ 10

Hence, we can buy 10 gallons of the gas from $30.

Answer:

the answer is c 1.2

Step-by-step explanation:

to calculate the iqr you have to do the following:

q3 - q1 = answer

4.5 - 3.3 = 1.2

The IQR(interquartile range) for the distribution of the song length is 1.2.

Interquartile range gives information on the spread of the middle half of your distribution.

Mathematically, the interquartile range can be represented as follows:

IQR = Q₃ - Q₁

where

Q₃ = 4.5

Q₁ = 3.3

Therefore,

IQR = 4.5  - 3.3

IQR = 1.2

Therefore, the interquartile range is 1.2.

Answer:

slope = 4/11

Step-by-step explanation:

To find the slope, use delta y/ delta x

(4,6) (-7,2)

(2-6)/(-7-4)

(-4)/(-11)

slope = 4/11

Let m = slope

m = difference of y-values divided by the difference of x-values.

m = (2 - 6)/(-7 - 4)

m = -4/-11

m = 4/11

Given:

[tex]\log_{a}(3) = 0.477,\log_{a}(5) = 0.699[/tex]

To find:

The value of [tex]\log_{a}(0.6)[/tex].

Solution:

We need to find the value of:

[tex]\log_{a}(0.6)[/tex]

It can be written as

[tex]\log_{a}(0.6)=\log_a\left(\dfrac{6}{10}\right)[/tex]

[tex]\log_{a}(0.6)=\log_a\left(\dfrac{3}{5}\right)[/tex]

By using the property of logarithm, we get

[tex]\log_{a}(0.6)=\log_a(3)-\log_a(5)[/tex]        [tex][\because \log \dfrac{a}{b}=\log a-\log b][/tex]

[tex]\log_{a}(0.6)=\log_a(3)-\log_a(5)[/tex]

On substituting the given values, we get

[tex]\log_{a}(0.6)=0.477-0.699[/tex]

[tex]\log_{a}(0.6)=-0.222[/tex]

Therefore, the values of [tex]\log_a(0.6)[/tex] is -0.222.
