I believe it is 150º because a supplementary angle is 180º so 180-30=150.

It takes 4 hours and 15 minutes to fly from Orlando, Florida, to Boston, Massachusetts. The distance between the two cities is 1

3241004551 [841]

Answer:

262.12mph and 419kph

Step-by-step explanation:

Given: It takes 4 hours and 15 minutes to fly from Orlando, Florida, to Boston, Massachusetts. The distance between the two cities is 1114 miles

To Find: the average speend of the plane in miles per hour, If every mile is approximately 1.6 kilometers, the speed of the airplane in kilometers per hour

Solution:

Distance between Orlando,Florida and Boston, Massachusetts $=1114$ $\text{miles}$

Time taken to cover the distance $=4\text{hours}$ and $15\text{minutes}$

We know that,

$\text{Average Speed}=\frac{\text{Total Distance}}{\text{Total time}}$

$=\frac{1114}{\frac{17}{4}}$

$=\frac{1114\times4}{17}$

$=262.12$ $\text{mph}$

It is given that,

$1\text{mile}=1.6\text{kilometer}$

therefore,

$1\text{mph}=1.6\text{kph}$

Speed Of plane in Kilometers per hours $=\text{speed in mph}\times1.6$

$419.4\text{kph}$

Speed of in miles per hour is $262.12$ $\text{mph}$ and Speed in kilometer per hour $419.4\text{kph}$

1. Answer:

30 is your frequency

Step-by-step explanation:

Frequency in this case would be the number of winners. So to find the frequency we would need to add up the total number of winners in the histogram.

So, 0 + 2 + 5 + 6 + 8 + 5 + 4 = 30

2. Answer:

6 (you already put that)

The median can be found in the 50-59 bin or interval.

What function equation is represented by the graph?

Ahat [919]

In the given graph, lets mark two points:

Let $A = (0,-3)$ and $B = (4,-2)$

The slope of the line is given by:

$m = \frac{(-2)-(-3)}{(4)-(0)}$

$m = \frac{-2+3}{4}$

$m = \frac{1}{4}$

The equation of the line is given by:

$(y-y_1)=m(x-x_1)$

$(y-(-3))=(\frac{1}{4})(x-0)$

$4(y+3)=x$

$4y+12=x$

$4y=x-12$

$y= \frac{1}{4}x-3$

Therefore, the function equation represented by the graph is: $f(x)= \frac{1}{4}x-3$

the gross income is $215 per week the deductions are $15.16,$29.33,2%,1%,and 3% what is the net income

Naddik [55]

State tax = 2% of $215 = 0.02 x $215 = $4.30
city tax = 1% of $215 = 0.01 x $215 = $2.15
retirement fund = 3% of $215 = 0.03 x $215 = $6.45

Total deductions = $15.16 + $29.33 + $4.30 + $2.15 + $6.45 = $57.39

Net income = $215 - $57.39 = $157.61
