Using the concept of combination, the value of the expression 9C4 is 126
Recall the combination formula :
[tex]nCr = \frac{n!} {(n-r)!r!} [/tex][tex]9C4 = \frac{9!} {(9-4)!4!} [/tex]
[tex]9C4 = \frac{9 \times 8 \times 7 \times 6} {4 \times 3 \times 2 \times 1} [/tex]
[tex]9C4 = \frac{3024} {24} = 126 [/tex]
Therefore, the value of the expression 9C4 is 126.

The table shows the temperature (y) at different altitudes (x).
This is a linear relationship. (Example 2)
2)Find the slope of this relationship
3)Find the y-intercept for this relationship
4)Write an equation in slop intercept form that represents this relationship
5)Use the equation to determine the temperature at an altitude of 5000 feet
Answer/Step-by-step explanation:
2. Using two pairs of values, (0, 59) and (2,000, 51),
[tex] slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{51 - 59}{2,000 - 0} = \frac{-8}{2,000} = -\frac{1}{250} [/tex]
3. The y-intercept is the value of y when x = 0. Thus, x = 0, when y = 59. Therefore,
y-intercept (b) = 59
4. To write an equation in slope-intercept form, simply substitute m = -¹/250, and b = 59, in [tex] y = mx + b [/tex]
✅[tex] y = -\frac{1}{250}x + 59 [/tex]
5. Substitute x = 5,000 in [tex] y = -\frac{1}{250}x + 59 [/tex].
[tex] y = -\frac{1}{250}(5,000) + 59 [/tex]
[tex] y = -20 + 59 [/tex]
[tex] y = 39 [/tex]
At an altitude of 5,000 ft, temperature would be 39°F

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.

Answer:
z = 3[tex]\sqrt{13}[/tex]
Step-by-step explanation:
Using the altitude- on- hypotenuse theorem
( leg of large Δ )² = ( part of hypotenuse below it ) × ( whole hypotenuse )
z² = 9 × (9 + 4) = 9 × 13 = 117 ( take square root of both sides )
z = [tex]\sqrt{117}[/tex]
= [tex]\sqrt{9(13)}[/tex]
= [tex]\sqrt{9}[/tex] × [tex]\sqrt{13}[/tex]
= 3[tex]\sqrt{13}[/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%

A kite string is 220 feet in length. It makes a 450 angle with the ground. How high is the kite off of the ground?
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

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)
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

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.
