If it is about 240 miles to the International Space Station, how many kilometers is 240 miles? Round your answer to the nearest whole kilometer. Press enter to interact with the item, and press tab button or down arrow until reaching the Submit button once the item is selected A388 kilometers B385 kilometers C387 kilometers D386 kilometers
Km = miles x 1.609
240 x 1.609 = 386.24 km
The answer is D. 386 kilometers
Answer:
D. 386
Step-by-step explanation:
If we know that we have 240 miles then we need to find the Km/m which is 1.60934 Km to 1 M, and we have the equation y= 1.60934(x), y bing the total amount of Km, or in other words, your answers, and x is the miles. Now change that x into 240 so now you have y= 1.60934(240) which comes out to 386.2416 Km or 386Km as seeing you have to round tho the nearest whole number.

FRACTION HAS TO BE IN DECMAL
Answer:
x intercept: (-1/7, 0) or (.14, 0)
y intercept: (0, 1/4) or (0, .25)
Step-by-step explanation:
Answer:
x- (−0.142857142857143,0)
y- (0, .25)
Step-by-step explanation:
The x-intercept:
Plug y=0 into the equation and solve the resulting equation 7x−5=−6 for x
(−1/7,0) = (−0.142857142857143,0)
The y-intercept:
Plug x=0 into the equation and solve the resulting equation −5=4y−6 for y
(0,1/4) = (0, .25)
An architect designs two similar triangular patios. The first patio has angle measures of (x + 10)°, (y + 15)°, and 70°. The second patio has angle measures of (x + 20)°, 50°, and 60°. Find the values of x and y.
Answer:
x is 50
y is 55
Step-by-step explanation:
Let us start working with the second patio
At any point in time, the total measure of the angles of a triangle is 180
Thus in the second patio;
x + 20 + 50 + 60 = 180
x + 130 = 180
x = 180-130
x = 50
In the first patio;
x + 10 + y + 15 + 70 = 180
substitute 50 for x
50 + 10 + y + 65 = 180
60 + 65 + y = 180
y = 180-60-65
y = 55
Answer:
the other answer above is wrong,
x=50
y=35

perpendicular to the line 4x - 6y + 7 = 0 , passing through (3, 4) .
Answer:
The equation of line perpendicular to given line passing through (3,4) is:
[tex]y = -\frac{3}{2}x+\frac{17}{2}[/tex]
Step-by-step explanation:
Given equation of line is:
[tex]4x - 6y + 7 = 0[/tex]
Given equation is in standard form. It has to be converted into slope-intercept form to extract slope from the equation.
So,
[tex]4x+7 = 6y\\6y=4x+7\\\frac{6y}{6} = \frac{4x+7}{6}\\y = \frac{4}{6}x+\frac{7}{6}\\y=\frac{2}{3}x+\frac{7}{6}[/tex]
The standard form of slope-intercept form of equation is:
[tex]y=mx+b[/tex]
Here, the co-efficient of x is the slope of the line.
So the slope of given line is: 2/3
m = 2/3
The product of slopes of two perpendicular lines is -1
Let m1 be the slope of line perpendicular to given line
Then
[tex]m.m_1 = -1\\\frac{2}{3} . m_1 = -1\\m_1 = -1*\frac{3}{2}\\m_1 = -\frac{3}{2}[/tex]
The equation of perpendicular will be:
[tex]y = m_1x+b[/tex]
Putting the value of slope
[tex]y = -\frac{3}{2}x+b[/tex]
To find the value of b, putting (3,4) in the equation
[tex]4 = -\frac{3}{2}(3)+b\\4 = -\frac{9}{2}+b\\b = 4+\frac{9}{2}\\b= \frac{8+9}{2}\\b=\frac{17}{2}[/tex]
So the equation of line perpendicular to given line passing through (3,4) is:
[tex]y = -\frac{3}{2}x+\frac{17}{2}[/tex]

Salvador’s investment of $2,200 in the stock market earned $528 in two years. Find the simple interest rate for this investment.
Answer:
24%Step-by-step explanation:
Step one:
given data
Principal= $2,200
SImple interest =$528
Time = 2years
Rate = ?
Required:
Rate R
The simple interest is expressed mathematically as
SI=PRT/100
substitute we have
528=2200*R*2/100
cross multiply
528*100=2200R
divide both sides by 2200
R=52800/2200
R=24%

Gerry arrived at the bus stop x hours past noon. Dale arrived 4 hours later. Pat arrived at 5 P.M., x hours after Dale.
At what time did Gerry arrive at the bus stop? [Your answer must include an A.M. or a P.M.]
Answer:
Gerry arrived at the bus station at 12:30 P.M.
Step-by-step explanation:
From noon and 5:00 P.M. there are 5 hours.
Gerry, Dale, and Pat arrived at the bus stop within that interval, which means the sum of the times elapsed between their arrival times must be 5.
4 out of the 5 hours elapsed since Gerry and Dale's arrivals. This means there is only one hour left for twice x.
If twice x is one hour, then x is half an hour. Thus, the complete sequence of arrivals is:
Gerry arrived at the bus station at 12:30 P.M.
Dale arrived at the bus station at 4:30 P.M.
Pat arrived at the bus station at 5:00 P.M.

Write the equation in slope-intercept form, identify the slope and the y-intercept.
(Slope-intercept form: y = mx + b)
-2x + 3y = -6
Answer:
Slope is 2; y-intercept is (0,-6)
Step-by-step explanation:
Slope intercept form looks like 3y = 2x - 6
In the equation y=mx+b, M is always the slope, and B is always the y-intercept. Therefore if you look back at the problem the slope number should be in front of the x which makes it 2. Since the y-intercept is always b, y = -6.
Slope or m = 2; y-intercept is (0,-6)
Answer:
y = [tex]\frac{2}{3}[/tex] x - 2
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Given
- 2x + 3y = - 6 ( add 2x to both sides )
3y = 2x - 6 ( divide all terms by 3 )
y = [tex]\frac{2}{3}[/tex] x - 2 ← in slope- intercept form
with slope m = [tex]\frac{2}{3}[/tex] and y- intercept c = - 2
