Step-by-step explanation:
the above question it is solve by cos that means cos=adjacent/hypotneus cos(23)=4.1/X then it become X=4.1/cos(23)X=4.45Joey, Keith, and Eli have a combined height of 7 meters. If Joey is 1 2/5 meters tall and Eli is 2 7/10 meters tall, how tall is Keith?
Answer: 2 9/10 or 2.9 metres
Step-by-step explanation: Form an equation with the information given
1 2/5 + 2 7/10 +x =7
Let x represent the height of Keith
Change mixed fractions into improper fractions
1 2/5=7/5 as an improper fraction we say 1*5+2=7 and put it over the denominator 5
2 7/10 =27/10 as an improper fraction we say 2*10+7 =27 and put it over the denominator 10
we now have the following:
7/5+27/10+x=7
We simplify these fractions by adding them up
7/5
7/5*2/2+27/10=14/10+27/10=41/10
41/10+x=7
To solve for x
take 41/10 from both sides
7-41/10
Making the denominators the same we get the following:
x=70/10-41/10=29/10=2 9/10

if a clock's second hand is one inch long, how many miles, to the nearest mile, does the second hand on the clock above travel in 7 days?
The hand will cover a distance of 1055.04 inches in 7 days.
To establish the distance covered by the hand's point would go in a week, we would first need to determine the radius of the clock's circle, for which the hand serves as a proxy .
To accomplish this, we would utilize the equation 2(pi*radius),
where pi equals 3.14.
The solution to p=2(3.14*1 ) is 6.28 inches.
This indicates that the hand's point moves 6.28inch every 1 hours.
To determine how far the hand moves in a 168 hour, we would multiply 6.28 inch by 168.
As a result, we arrive at the final calculation of 168 inches covered in 7 days as 1055.04 inches.

Please help graph question
Answer:
a. (-2,-1)
b. y = -(1/2)x-2
Step-by-step explanation:
We will look for an equation of the form y=mx+c, where m is the slope and b is the y-intercept (the value of y when x = 0).
Put the two given points into a table to make it easier to calculate the slopes for Lines A and B. See the attachment for the table. Slope is the change in y for a change in x, often termed the "Rise/Run." Using Line A as the example, the change in y (the Rise) is obtained by taking the Point 2 value for y (7) and subtracting the Point 1 value for y (3): Rise = (7 - 3) = 4. The Run is obtained by taking the Point 2 value for x (2) and subracting the Point 1 value of x (0). The ratio of Rise/Run is 4/2, so the slope is 2. The same process is used for Line B to obtain a slope of 3 for that line.
The two equations can be written with these slopes:
Line A: y = 2x + c
Line B: y = 3x + c
We need to find a value of c for each equation that will force the line through either of their two given points. c can be determined by entering either of that line's points into the equation(s) above and solving for c:
Line A:
y = 2x + c
3 = 2*(0) + c for point (0,3)
c = 3
The equation for Line A is y = 2x + 3
Line B:
y = 3x + c
2 = 3*(-1) + c for point (-1,2)
c = 5
The equation for Line B is y = 3x + 5
The graph of these lines is attached. They intersect at point (-2,-1).
[As a note, the solution may also be found by using substitution and solving for both x and y:
y = 2x+3
y = 3x+5
The solution exists when both y's and x's are equal:
Assume y is equal:
2x+3 = 3x+5
-x = 2; x = -2
----
Assume x is equal:
Rearrange:
y = 2x+3
2x = y-3
x = (y-3)/2
Use this definition of x in the second line equation:
y = 3x+5
y = 3((y-3)/2)+5
y = (3y - 9)/2 + 5
2y = 3y - 9 + 10
-y = 1
y = -1
The solution is (-2,-1), the same as was found by graphing.]
==================================================
A perpendicular line has a slope that is the negative inverse of the referenced line. For Line A, the perpendicual line would be -(1/2). The equation for this line would take the form y = -(1/2)x + c. We want this perpendicular line to intersect the same point that is the solution to the first problem: (-2,-1). Enter this point to find c:
y = -(1/2)x + c
-1 = -(1/2)*(-2) + c for (-2,-1)
-1 = 1+ c
c = -2
The perpendicular line is y = -(1/2)x - 2

A boat take 4 hour to travel uptream 30 mile. On the return trip downtream it took 2 hour. What i the peed of the boat if it were in till water? What i the peed of the current?
The speed of the boat if it were in still water is 11.25 miles per hour and the speed of the current is 3.75 miles per hour.
According to the question,
We have the following information:
A boat take 4 hour to travel upstream 30 miles. On the return trip downstream it took 2 hours.
Now, let's take the speed of the boat in still water to be s miles per hour and the speed of the current to be c miles per hour.
Upstream speed = speed in still water - speed of current
Downstream speed = speed in still water + speed of current
Upstream:
s-c = 30/4
s-c = 7.5
s = 7.5+c ...(1)
Downstream:
s+c = 30/2
s+c = 15
Putting the value of s from equation 1:
7.5+c+c = 15
7.5+2c = 15
2c = 15-7.5
2c = 7.5
c = 7.5/2
c = 3.75 miles per hour
Putting this value in equation 1:
s = 7.5+c
s = 7.5+3.75
s = 11.25 miles per hour
Hence, the speed of the boat if it were in still water is 11.25 miles per hour and the speed of the current is 3.75 miles per hour.

The 100 percent is 48 and the 125 percent of 48 is 60 .
Answer:
48
Step-by-step explanation:
"What is 60 is 125% of"
Put this sentence into an expression. The wording is awkward in the question. " . . is 60 is 125% of" is not a complete sentence. I believe it is asking what number results in 60 when we take 125% of it. I'll rephrase it as "125% of what number is 60." Please check my logic on this interpretation.
Write this as an expression, using N for the unknown "number:"
125% (N) = 60
(1.25N) = 60
N = 60/1.25
N = 48
125% of 48 is 60
find the measure of each interior angle and each exterior angle of a regular pentagon.
The measure of each interior angle of a regular pentagon is 108° and each exterior angle is 72°.
How to calculate the measure of each interior and exterior angle of a regular polygon?To calculate the measure of each interior and exterior of a regular polygon, we have the following formulae:
The measure of each exterior angle of a regular polygon with n sides is given by "360/n".
And the measure of each interior angle of a regular polygon with n sides is given by "180 - 360/n".
Calculation:The number of sides of a regular pentagon is n = 5.
So, the measure of each exterior angle of the regular pentagon is
= 360/n
⇒ 360/5 = 72°
Thus, the measure of each interior angle of the regular pentagon is
= 180 - 360/n
⇒ 180 - 72 = 108°
Therefore, the measure of each interior and exterior angle of a regular pentagon are 108° and 72°.

S:{11}
S:{14}
S:{30}
S:{42}
Answer:
The answer is n < 14.
Step-by-step explanation:
First, we need to distribute 6, then 3 through the parentheses.
6n - 30 < 3(n + 4)
6n - 30 < 3n + 12
We now need to move the variable to the left-hand side and change its sign.
6n - 30 - 3n < 12
Next, we have to move the constant to the right-hand side and change its sign.
6n - 3n < 12 + 30
Now we need to collect like terms.
3n < 12 + 30
Then, we need to add the numbers.
3n < 42
Last but not least, we need to divide both sides of the inequality by 3. This gets us to:
n < 14
