What is the length of Line segment A B? Round to the nearest tenth. Triangle A B C is shown. Angle A C B is a right angle and angle C A B is 75 degrees. The length of C A is 10 meters and the length of hypotenuse A B is x. 9.7 m 10.4 m 37.3 m 38.6 m
Answer:
AB = 38.6metres
Step-by-step explanation:
Given the right angled triangle ABC with hypotenuse AB and ∠CAB to be 75°, the opposite side of the triangle will be the side facing the angle ∠CAB directly and this is side BC. The adjacent side of the triangle will be side CA.
To get the length of the hypotenuse AB, we will use the trigonometry identity SOH, CAH, TOA.
According to CAH;
Cos∠CAB = adjacent/hypotenuse = CA/AB
Substituting CA = 10 metres and ∠CAB = 75° into the equation;
Cos75° = 10/AB
AB = 10/cos75°
AB = 10/0.2588
AB = 38.6metres
Hence the length of the hypotenuse AB is 38.6metres.
Answer:
38.6 m

A caterer estimates that 2 gallons of fruit punch will serve five people.
How much additional punch is necessary to serve 75 people?
Need all the explanations
Answer:
the answer is 28
Step-by-step explanation:
This is simple
if 5 people need 2 gallons we can use that to figure out how many gallons 75 people need.
75 divided by 5 is 15. so if 5 fits into 75 15 times that means that 75 people need 15 times 2 gallons or 30 gallons of fruit punch.
But the problem ask how much "additional" fruit punch so we subtract 2 from 30 to get 28 additional gallons of fruit punch
The image of the point (-1,-8) under a translation is (0, -11). Find the coordinates of the image of the point (-4,-1) under the same translation.
Answer:
(-3,-4)
Step-by-step explanation:
● (-1,-8) => (0,-11)
Notice that to move from -1 to 0 in the x-axis we should go one unit to the right wich means adding 1.
● -1 + 1 = 0
Notice that to move from -8 to -11 in the y-axis we should go 3 units down wich means substracting 3.
● -8-3 = -11
Let's do the same for the second point.
● (-4,-1) => ?
Add 1 to -4
● -4+1 = -3
We moved 1 unit to the right by adding 1
Substract 3 from -1
● -1-3 = -4
We moved down 3 units by substracting 3
So the image of (-4,-1) is (-3,-4)
Two gardens are being fenced in. Both gardens will require the same amount of fencing (both gardens have the same perimeter in meters). One garden is in the shape of a square and the other is in the shape of an equilateral triangle. Each side of the triangle is 1 meters longer than each side of the square.
Answer:
The side length of the square is 3 meters.
The side length of the triangle is 4 meters.
Step-by-step explanation:
This is basically a systems of equations word problem.
To solve this, we have to create two different equations. Let's assume [tex]s[/tex] is the side length of the square and [tex]t[/tex] is the side length of the triangle.
We can make the equation [tex]4s=3t[/tex], since the perimeters are the same. (A square has 4 sides, a triangle has 3 - multiplying by the side length of each will get perimeter)
We also know that the side length of the triangle is 1 meter longer than the side length of the square, so the equation here becomes [tex]t = s+1[/tex].
Now, let's substitute the second equation ([tex]t = s+1[/tex]) into the first ([tex]4s=3t[/tex]).
[tex]4s = 3(s+1)[/tex]
Apply the distributive property:
[tex]4s = 3s+3[/tex]
Subtract 3s from both sides:
[tex]s=3[/tex]
So the side length of the square is 3. We can now plug it into the equation [tex]t = s + 1[/tex] to find the side length of the triangle.
[tex]t = 3+1\\\\t=4[/tex]
Hope this helped!

Sampling every 100th invoice would be an example of:_______a. Randomization.b. Proxemics.c. Stratification.d. JRP.e. Observation.
Answer: C. Stratification
Step-by-step explanation: There are diverse samping techniques employed for statistical purposes depending on the tipe and nature of data available or other factors. When a data population is sampled in sects such that the entire data is divided into a equals groups at a fixed intervals based on a certain criteria, it is called stratified sampling. Here, data is divided into strata, with each stratum containing a fixed amount of samples with each partition taking place at regular interval. In the scenario stratification process is employed by sampling at a fixed and regular interval, however, the random nature of the data is not violated.
Write an equation that represents the perimeter of the rectangle. The width of a rectangle is 9 less than one-third it's width, when the perimeter is 45.
Answer:
The equation that represents the perimeter of the rectangle is:
[tex]\text{Perimeter} = \frac{2}{3} \times [4l-27][/tex]
Step-by-step explanation:
The perimeter of a rectangle is given by the formula:
Perimeter = 2 × [l + w]
It is provided that the width of a rectangle is 9 less than one-third it's length.
That is:
[tex]w = \frac{1}{3}l-9[/tex]
The perimeter is given as 45.
The equation that represents the perimeter of the rectangle is:
[tex]\text{Perimeter} = 2 \times [l + \frac{1}{3}l-9]\\\\\text{Perimeter} = 2 \times [\frac{3l+l-27}{3}]\\\\\text{Perimeter} = 2 \times [\frac{4l-27}{3}]\\\\\text{Perimeter} = \frac{2}{3} \times [4l-27][/tex]
Thus, the equation that represents the perimeter of the rectangle is:
[tex]\text{Perimeter} = \frac{2}{3} \times [4l-27][/tex]

Suppose a regular n-gon is inscribed in a circle of radius r. Diagrams are shown for n=6, n=8, and n = 12. n = 6 n=8 n = 12 a a VT a Imagine how the relationship between the n-gon and the circle changes as n increases. 1. Describe the relationship between the area of the n-gon and the area of the circle as n increases.
Answer:If an N-gon (polygon with N sides) has perimeter P, then each of the
N sides has length P/N. If we connect two adjacent vertices to the
center, the angle between these two lines is 360/N degrees, or 2*pi/N
radians. (Do you understand radian measure well enough to follow me
this far?)
The two lines I just drew, plus the side of the polygon between them,
form an isosceles triangle. Adding the altitude of the isosceles
triangle makes two right triangles, and we can use one of them to
derive the equation
sin(theta/2) = s/(2R)
where theta is the apex angle (which I said is 2*pi/N radians), R is
the length of the lines to the center (the radius of the circumscribed
circle), and s is the length of the side (which I said is P/N).
Putting those values into the equation, we have
sin(pi/N) = P/(2NR)
so that
P = 2NR sin(pi/N)
gives the perimeter of the N-gon with circumradius R.
Can we see a connection between this formula and the perimeter of a
circle? The perimeter of the circumcircle is 2*pi*R. As we increase
N, the perimeter of the polygon should get closer and closer to this
value. Comparing the two, we see
2NR*sin(pi/N) approaches 2*pi*R
N*sin(pi/N) approaches pi
You can check this out with a calculator, using big numbers for N such
as your teacher's N=1000. If you calculate the sine of an angle in
degrees rather than radians, the formula will look like
N*sin(180/N) --> pi

Please help ASAP!!! ILL NAME YOU BRAINLIEST!!!
Answer:
18
Step-by-step explanation:
We can create a ratio of the amount of students who picked green over the total amount of students.
9 students picked the green pattern, and a total of 50 students were surveyed. This means the ratio is [tex]\frac{9}{50}[/tex].
To turn [tex]\frac{9}{50}[/tex] into a percentage, we must divide it's numerator by it's denominator and multiply by 100.
[tex]8\div50=0.18\\\\0.18\cdot100=18[/tex]
So the green bar's height will be 18.

Find the slope of the line that passes through each pair of points. Express as a fraction in simplest form. (-6, -2), (-1.5, 5.5)
Answer:
m = slope= 5/3
Step-by-step explanation:
[tex](-6, -2) = (x_1,y_1) \\ (-1.5, 5.5) (x_2 ,y_2) \\ \frac{y - y_1}{x - x_1} = \frac{y_2 - y_1}{x_2 -x _1} [/tex]
[tex] \frac{y - ( - 2)}{x - ( - 6)} = \frac{5.5 - ( -2 )}{ - 1.5 - ( - 6)} \\ \frac{y + 2}{x + 6} = \frac{5.5 + 2}{ - 1.5 + 6} [/tex]
[tex] \frac{y + 2}{x + 6} = \frac{7.5}{4.5} \\ 4.5(y + 2) = 7.5(x + 6)[/tex]
[tex]4.5y + 9 = 7.5x + 45 \\ 4.5y = 7.5x + 45 - 9 \\ 4.5y = 7.5x + 36[/tex]
Divide through by 4.5
[tex] \frac{4.5y}{4.5} = \frac{7.5x}{4.5} + \frac{36}{4.5} \\ y = \frac{5}{3} x + 8 \\ [/tex]

This is rlly easy but Im to lazy to do it- I mark brainliest.
Answers:
A. 6 Large taxis = 42 seats 9 Small taxis = 36 seats = 78 seats in total
B. 6 Large taxis = $498 + 9 Small taxis = $450 498+450= $948
C. 5 Large taxis and 10 Small taxis
Step-by-step explanation:
A. 6 Large taxis = 42 seats 9 Small taxis = 36 seats = 78 seats in total
If I did 8 small taxis the total number of seats would be 74, so I did one small taxi more to make it fair. There would be seats for everyone but 3 seats extra
B. 6 Large taxis = $498 + 9 Small taxis = $450 498+450=948
C. 5 Large taxis and 10 Small taxis
While the more small taxis there are, the more cheaper it is for Max but the less seats there would be for 75 people, So I did 1 more small taxi and 1 less large taxi.
The total number of seats now is 75 seats which is perfect amount for 75 people
So the total cheaper cost would $915 while still maintaining a fair amount of seats which is 75
Use the number line below, where RS = 7y +3, ST = 5y +8, and RT = 83.
a. What is the value of y?
b. Find RS and ST
a. What is the value of y?
Answer:
Step-by-step explanation:
Given the vectors based on the number line as RS = 7y +3, ST = 5y +8, and RT = 83, the equation RS+ST = RT will be used to get the unknown.
Substituting the given equation into the expression we will have;
7y +3+5y +8 = 83
collect like terms'
7y+5y+3+8 = 83
12y + 11 = 83
12y = 83-11
12y = 72
y = 72/12
y = 6
b) Substitute y = 6 into RS and ST
Given RS = 7y+3
RS = 7(6)+3
RS = 42+3
RS = 45
For ST;
ST = 5y+8
ST = 5(6)+8
ST = 30+8
ST = 38

Find an equation of the circle that satisfies the given conditions. Endpoints of a diameter are P(−2, 1) and Q(8, 9)
Answer:
Equation of the circle (x-3)²+(y-5)²=(6.4)²
x² -6x +9 +y² -10y +25 = 40.96
Step-by-step explanation:
Step(i):-
Given endpoints of diameter P(−2, 1) and Q(8, 9)
Centre of circle = midpoint of diameter
Centre = [tex](\frac{-2+8}{2} ,\frac{1+9}{2} )[/tex]
Centre (h, k) = (3 , 5)
Step(ii):-
The distance of two end points
PQ = [tex]\sqrt{(x_{2}-x_{1} )^{2} +(y_{2} -y_{1} )^{2} }[/tex]
[tex]PQ= \sqrt{(8+2 )^{2} +(8 )^{2} }[/tex]
PQ = √164 = 12.8
Diameter d = 2r
radius r = d/2
Radius r = 6.4
Final answer:-
Equation of the circle
(x-h)²+(y-k)² = r²
(x-3)²+(y-5)²=(6.4)²
x² -6x +9 +y² -10y +25 = 40.96
x² -6x +y² -10y = 40.96-34
