Name all the angles that have V as a Vertex
Answers
Answer:
Step-by-step explanation:
An angle is formed by joining two rays or two lines meeting at a point.
Common endpoint is called the vertex of the angle.
From the picture attached,
Three rays VJ, VI and VH are meeting at a common point V.
Therefore, angles formed at the common vertex V are,
Angle between ray VJ and VI,
(∠5 or ∠JVI)
Angle between ray VH and VI
(∠6 or ∠HVI)
Angle between ray VJ and VH
∠JVH.
A triangle has two sides of length 19 and 3. What is the largest possible whole number length for the third side?
Answers
========================================================
Explanation:
Consider a triangle with side lengths a,b,c such that a < b < c
a = 3 and b = 19 are the two known sides
Let c be the missing side length
The missing side has the property that...
b-a < c < b+a
19-3 < c < 19+3
16 < c < 22
Meaning that if c is a whole number then it can take on any of these values {17, 18, 19, 20, 21}
So c = 21 is the largest possible third side, where only whole number sides are considered.
We can't have a third side of 22 because the two other sides add to a+b = 3+19 = 22 and a triangle wouldn't form (instead only a straight line would). I recommend cutting out strings of paper trying this out yourself.
---------------
Side note: The inequality b-a < c < b+a is a variation of the triangle inequality theorem.
a scale on a map reads 2in 150ft find the actual distance if the length on a map is 4.5 inches
Answers
Answer:
4.5 in. is equivalent to 337.5 ft.
Step-by-step explanation:
The given parameters are;
The scale of the scale map is 2 in. to 150 ft.
The measured length on the scale map = 4.5 inches
The actual distance of the location is given as follows;
2 in. is equivalent to 150 ft.
Therefore;
1 in. is equivalent to 150 ft./2 = 75 ft.
4.5 in. will be equivalent to 4.5 × 75 ft. = 337.5 ft.
4.5 in. will be equivalent to 337.5 ft.
The equation below can be used to determine I, the am
simple interest on a loan.
I= prt, where p is the principal, r is the rate of the loan,
the length of the loan in years.
Which of these is the equation solved in terms of r?
Answers
Given :
The equation below can be used to determine I (simple interest) on a loan as follows :
[tex]I=Prt[/tex] ...(1)
P is principal, r the rate of the loan, t is the length of the loan in years.
We need to find the equation to solve in terms of r. We can find the value of P.
Dividing both sides of equation (1) by rt. So,
[tex]\dfrac{I}{rt}=\dfrac{Prt}{rt}\\\\P=\dfrac{I}{rt}[/tex]
So, P can be solved as : [tex]P=\dfrac{I}{rt}[/tex].

There are 2 overlapping triangles here. If the vertical lines are parallel, then these triangles are similar, and corresponding sides occur in a fixed ratio. In particular, we have

2/3 = (2 + x) / (10 + x)

Zelie planned for a square pool to have a side length of 28 ft but found that it needs to be 14 ft long to fit in her backyard. She found the change of scale below. StartFraction 28 feet minus 7 over 14 feet minus 7 EndFraction = StartFraction 21 over 7 EndFraction Which is Zelie's error? Zelie should have divided both numbers by 14. Zelie should have written the ratio as StartFraction 28 feet over 7 feet EndFraction. Zelie should have written the ratio as StartFraction 14 feet over 28 feet EndFraction.
Answers
Answer:
Zelie should have divided both numbers by 14
Step-by-step explanation:
Given
[tex]Actual = 28[/tex]
[tex]Measured = 14[/tex]
Required
Spot and correct Zelie's mistake
[tex]Zelie = \frac{28 - 7}{14 - 7} = \frac{21}{7}[/tex]
Scale is calculated as:
[tex]Actual = Measured * Scale[/tex]
[tex]28 = 14 * Scale[/tex]
Divide 28 and 14 by 14
[tex]28/14 = 14/14 * Scale[/tex]
[tex]2 = 1 * Scale[/tex]
[tex]2 =Scale[/tex]
[tex]Scale = 2[/tex]
Notice at this point:
[tex]28/14 = 14/14 * Scale[/tex]
Both sides were divided by 14.
Hence, option A answers the question.
Answer:
A. Zelie should have divided both numbers by 14.

Write equation in slope intercept form (x=mx+b). Find the slope (x) and the y-intercept (b) of the line
Answers
Answer:
y = (2/3)x - 1
Step-by-step explanation:
By refering the graph, we can see that y-intercept(b) = (a point of the y-axis) which is -1.
the coordiates i have taken:
(-3 , -3) ------ (-3 =x1, -3 =y1)
and
( 3, 1 ) --------( 3 = x2, 1 = y2)
To find slope,
slope(m) = rise/run = ( y2 - y1 ) / ( x1 - x2 )
=> ( 1 - (-3) ) / ( 3 - (-3) ) -----( negative × negative = positive. Hence the signs are positive. )
=> ( 1 + 3 ) / ( 3 + 3 )
=> 4 / 6
=> 2 / 3 ------(simplied after numerator and denominator got divided by 2)
now,
b = -1
m = 2/3
x = x ----(x remains same)
Therefore,
y=> mx + b
by substituting the values, we get,
y=> (2/3)x - 1
