Answer:

1 lap in 60 seconds

Step-by-step explanation:

This is the answer because:

1) Think of it as ratios or fractions

Ratio: 3:180

2) Next, we have to find something equivalent. Since 3 can only be multiplied by one or itself, we have to dived 3 by 3.

3) 3 divided by 3 is 1

2) 180 divided by 3 is 60

4) This equals to 1:60

Therefore, the answer is 1 lap in 60 seconds

Hope this helps!

Step-by-step explanation:

Why are you asking? Why isn't your friend?

The diagram assumes that the angle on the lower left of the triangle is a right angle. If it is not, then I don't think there is a way that this can be solved.

Tan(A) = opposite / adjacent

opposite = 7

Adjacent = 4

Tan(A) = 7/4 = 1.75

A = inverseTan (1.75)

A = 60.60 degrees

Answer:

R=60

S=55

T=65

Step-by-step explanation:

[tex]\boldsymbol{m\angle R, m\angle S, m\angle T}[/tex] are equal to [tex]\boldsymbol{60^{\circ},55^{\circ},65^{\circ}}[/tex] respectively.

According to angle sum property of a triangle, sum of all angles of a triangle is equal to [tex]\boldsymbol{180^{\circ}}[/tex]

Let [tex]m\angle R=x[/tex]

As [tex]m\angle T[/tex] is [tex]5^{\circ}[/tex] more than [tex]m\angle R[/tex],

[tex]m\angle T=5^{\circ}+m\angle R[/tex]

[tex]\boldsymbol{m\angle R=m\angle T-5^{\circ}}[/tex]

Also,

[tex]m\angle S[/tex] is [tex]10^{\circ}[/tex] less than [tex]m\angle T[/tex],

[tex]\boldsymbol{m\angle S=m\angle T-10^{\circ}}[/tex]

So,

            [tex]\boldsymbol{m\angle R+m\angle S+m\angle T=180^{\circ}}[/tex]

[tex]m\angle T-5^{\circ}+m\angle T-10^{\circ}+m\angle T=180^{\circ}[/tex]

                       [tex]3m\angle T-5^{\circ}-10^{\circ}=180^{\circ}[/tex]

                                           [tex]m\angle T=\frac{195^{\circ}}{3}[/tex]

                                                    [tex]\boldsymbol{=65^{\circ}}[/tex]

[tex]m\angle R=65^{\circ}-5^{\circ}[/tex]

         [tex]\boldsymbol{=60^{\circ}}[/tex]

[tex]m\angle S=65^{\circ}-10^{\circ}[/tex]

        [tex]\boldsymbol{=55^{\circ}}[/tex]

Answer:

A

Step-by-step explanation:

The equation of line is y= -4x -23

A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. 

The slope of the line is the ratio of the rise to the run, or the rise divided by the run, therefore the change in y coordinate with regard to the change in x coordinate may be expressed as follows. In the coordinate plane, it describes the slope of the line.

Given:

We can take the coordinates from the given graph as (0, 3) and (2, -5)

Now, the slope = (-5 - 3)/ (2 - 0)

slope= -8/ 2

slope= -4

Now, using the point- slope form

(y - [tex]y_1[/tex]) = m(x - [tex]x_1[/tex])

(y- (-3))= -4( x- (-5))

y+3 = -4(x+5)

y+ 3= -4x - 20

y= -4x -23

Hence, the equation of line is y= -4x -23.

Answer:

Sample mean (xbar) = 40

Step-by-step explanation:

Given that :

Sample size (n) = 64

Population mean (μ) = 40

Standard deviation (σ) = 5

The sample mean is equal to the population mean according to the central limit theorem.

The sample standard deviation = standard error = ;

Standard Error = σ / √n

Standard Error = 5 / √64

Standard Error = 5 / 8

Standard Error = 0.625

Answer:

r = 24

Step-by-step explanation:

Just reverse everything,

3 x 16 = 48,

48 ÷ 2 = 24,

to double-check,

if you plug in 24 for r then you have,

2(24)/3 = 16

48/3 = 16

16 = 16

Answer:

Mean = 0.45

Standard deviation = 0.04035

Step-by-step explanation:

This is actually a very simple problem.

The question gives us the report that 45% of the teenagers in the age bracket own smartphones.

P = mean = 45%

Therefore the mean is 0.45.

I will go ahead to help you calculate the standard deviation.

√p(1-p)/n

n = 152

P = 0.45

√0.45(1-0.45)/152

= √0.45(0.55)/152

= √0.2475/152

= √ 0.001628

= 0.04035

Answer:

Step-by-step explanation:

Step-by-step-explanation

The first thing you would do is multiply both numbers inside the parenthesis by -3.

You would get -21 + (-15) or you could just wrtie -21 - 15, whichever is easier for you.

Then you'd simply add both -21 and -15 together, and you get -36. :D

The ordered pair which is the solution of the given inequalities is (A) (1,5).

So, to find the correct values we need to use the hit-and-trial method:

Step-by-step explanation:

f(x) = 2x - 7 - 3

~Combine like terms

f(x) = 2x - 10

When x = 2...

f(x) = 2(2) - 10

f(x) = 4 - 10

f(x) = -6

When x = 3...

f(x) = 2(3) - 10

f(x) = 6 - 10

f(x) = -4

When x = 4...

f(x) = 2(4) - 10

f(x) = 8 - 10

f(x) = -2
