Ray TV bisects ∠RTS, so ∠RTV=∠STV=(16x-6)ºWe also know that ∠RTS=(26x+18)ºSo, (16x-6)º+(16x-6)º=(26x+18)ºWe don't need parenthesis, 16x-6+16x-6=26x+18Combine like terms, 32x-12=26x+18Add, 32x=26x+30Subtract, 6x=30Divide, x=5∠RTV now is [16(5)-6]º=(80-6)º=74ºRam can travel 20km by a motorcycle in 1 litre of petrol.how far can he travel from 5 litres of petrol?Also,how much petrol will be needed to travel 750km.
Answer:
On 5 liters of petroleum he can go 100km.
He needs 37.5 liters of petroleum to go 750km.
Step-by-step explanation:
He goes 20km on 1 liter. Now we must find how far he can go on 5 liters.
1 * 5 = 5
20 * 5 = 100
The reason we multiplied was because we had to multiply 1 by 5 to get the number of liters of petroleum and what you to one side you must do to the other.
To find how many liters are needed to go 750km you must divide:
750/20 = 37.5
He needs 37.5 liters of petroleum to travel 750km.

PLEASE HELP!!!!! 1.) Line a passes through points (-2, 1) and (2, 9). Write an equation in slope intercept form that is parallel to line a. 40POINTS
Answer:
y=2x
Step-by-step explanation:
compute the slope first-
(-2,1) and (2,9)
m = 9-1/2-(-2) = 8/2+2= 8/4 = 2
knowing the slope take a given point and substitute it's x and y values into the equation to solve for 'b' the y-intercept-
y = mx + b,
1 = 2(-2) + b,
1 = -4+ b,
b = 5
our equation is y = 2x + 5
if you want an equation parallel to the line it has to have the same slope. Take y = 2x
Answer: y=2x+5
Step-by-step explanation:
To find line a in slope-intercept form, we first want to find the slope. The formula for slope is [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex].
[tex]m=\frac{9-1}{2-(-2)} =\frac{8}{4}=2[/tex]
Now that we know the slope, we can plug in any point to find the y-intercept.
y=2x+b [plug in any point]
9=2(2)+b [multiply]
9=4+b [subtract both sides by 4]
b=5
The final equation is y=2x+5.

angle B = angle E
E = B
12x+30 = 50
12x = 50-30
12x = 20
x = 20/12
x = 10/6

Now move to the equation involving C and F to get
F = C
(y/2) - 10 = 40
y/2 = 40+10
y/2 = 50
y = 2*50
y = 100

And finally,

=======================================================
Problem 11
The radius of the circle is r = 5.
The area of the circle is A = pi*r^2 = pi*5^2 = 25pi
The diameter of the circle is 2*r = 2*5 = 10, which is the side length of the square because the circle is fit perfectly inside the square.
Since the square side length is 10, the area is 10^2 = 100
Subtract the two areas: large-small = square - circle = 100 - 25pi
We subtract the areas because we're basically kicking out the circle area when we don't shade it. Think of it like sawing out that portion of a wooden block perhaps.
=======================================================
Problem 19
Part (a)
The point P is directly below the center and it is on the circle.
The location of point P is (18,0) because the x coordinates of both points are the same (so that P is directly below the center) and P resides on the x axis. All points on the x axis have y coordinate 0.
------------------------------
Part (b)
The radius of the circle is r = 10 which is the distance from the center to point P.
The area of the circle is therefore A = pi*r^2 = pi*10^2 = 100pi
Answer: 100pi
A european business has offered to donate to the Salvation Army, but they are requiring a detailed report on expenditures. Chase and his brother are tasked with converting distances measured in miles to kilometers. To estimate the number of kilometers, Chase takes the number of miles, doubles it and then subtracts 20% of the result. Alex, Chase's brother, first divides the number of miles by 5 and then multiplies the result by 8.
Answer:
Both processes are correct.
Step-by-step explanation:
Let the mile taken by Chase be 10miles .
He doubles it so it will be 20 and
20% of 20 will be 4
20-4 = 16km
Now Alex operations
(10/5 )*8 = 2*8= 16 km
In both cases the answer will be the same
1 mile = 1.60034 km
Now 10 miles = 16.00 34 km
which is the same as above.
Both the processes are correct.

Answer:
-3
Step-by-step explanation:
Slope of a line is "rise over run". Pick two points on the line. For example, (0,4) and (1,1). As we move from the first point to the second, we move down 3 units and right 1 unit. So the slope is -3/1 = -3.
Here's an algebraic approach. If the two points are (x₁, y₁) and (x₂, y₂), then the slope is:
m = (y₂ − y₁) / (x₂ − x₁)
Plugging in our two points:
m = (1 − 4) / (1 − 0)
m = -3

Is this true or false? Pls help a dumb person out
Answer:
false
Step-by-step explanation:
this is showing 2/-3
Answer: False.
Step-by-step explanation:
The slope is the difference in the y coordinates of any two points being divided by the difference between the x coordinates of the same two points.
Using the point, (0,5) and (3,3) find the difference in the y coordinates and divide it by the difference in the x coordinates to find the slope.
y: 5 - 3 = 2
x : 0 - 3 = -3
Slope: -2/3
This is indeed true because line is going downright so the slope has to be negative.

interchange both sides[tex]{:}\dashrightarrow [/tex][tex]\sf x=20+4 [/tex]
[tex]{:}\dashrightarrow [/tex][tex]\sf x=24[/tex]
The value of x is 30 if the triangles FGH and JKL are similar after using the property of the similarity triangles.
What is the similarity law for triangles?It is defined as the law to prove that the two triangles have the same shape, but it is not compulsory to have the same size. The ratio of the corresponding sides is in the same proportions and the corresponding angles are congruent.
It is given that:
The triangle FGH and JKL are shown in the picture.
(x + 35)/20 = (x - 4)/8
Cross multiplication:
8(x + 35) = 20(x - 4)
8x + 280 = 20x - 80
20x - 8x = 280 + 80
12x = 360
x = 360/12
x = 30
Thus, the value of x is 30 if the triangles FGH and JKL are similar after using the property of the similarity triangles.
