Angle STV is a right angle.
The measure of angle STW is 55°.
The measure of angle WTV is xº.
What is the value of x?

?
Answer:
x= 35
Step-by-step explanation:
STV°= WTV° + STW°
STV°=90
WTV°=x
STW°=55
subtitute in above:
90= x + 55
x= 90-55
x= 35
Two angles are supplementary. The measure of the larger angle is 36 more than the measure of the smaller angle. Find their measures.
the answers are 72° and 108° but I need help showing my work
x = smaller angle
x+36 = larger angle, since its 36 degrees more than the smaller angle
The two angles x and x+36 must add to 180 if they are to be supplementary (aka form a straight line)
So this means we can say the following:
(smaller)+(larger) = 180
(x) + (x+36) = 180
2x+36 = 180
2x = 180-36
2x = 144
x = 144/2
x = 72 is the smaller angle
x+36 = 72+36 = 108 is the larger angle
As a check:
smaller+larger = 72+108 = 180
which shows they are supplementary and it confirms our answers
Step-by-step explanation:
let the smaller angle be x
then the measure of larger angle will be x+36
x+x+36=180°(being supplementary angle)
2x+36=180°
2x=180°-36
2x=144°
x=144°/2
x=72°
now,
the larger angle x+36 = 72+36=108°

2- 7/8 (48x-8)+4=3(5x-19)
9514 1404 393
Answer:
infinite solutionsx = -2Step-by-step explanation:
1. The equation simplifies as follows:
5(x +2) =10 +5x
5x +10 = 5x +10 . . . . . eliminate parentheses, write in standard form
0 = 0 . . . . . . . . . . . . . . subtract 5x+10 from both sides
This is true for all values of x. Any value of x is a solution to this equation. There are an infinite number of solutions.
__
2. 7/8(48x -8) +4 = 3(5x -19) . . . . given
42x -7 +4 = 15x -57 . . . . . . . . eliminate parentheses
25x = -50 . . . . . . . . . . . . . add 7-15x to both sides
x = -2 . . . . . . . . . . . . . . divide by 25
Check
7/8(48(-2) -8) +4 = 3(5(-2) -19) . . . . substitute for x
7/8(-96 -8) +4 = 3(-10 -19)
7/8(-104) +4 = 3(-29)
-91 +4 = -87 . . . . . . . . . . true

for f(x) evaluate each of the following:
a. f(0)
b. f(6)
show all your work
Answer:
Step-by-step explanation:
a)
f(0) is just the function f(x) evaluated at 0, meaning we need to plug in 0 to the function.
What piece of this function should we plug 0 in? Well, because 0 is less than 5, plug it into the first piece.
so f(0) = 0 + 4 = 5
b)
By similar reasoning:
f(6) = 8
because 5 <= 6 < 7

Use the graph of f(x) to explain the relationship
between the real zeros of f(x) and its intercept(s).
4
A. f(x) has one real zero at --2 because the graph of the
function has an intercept at (0.-2).
B. f(x) has two real zeros at -4 and -2 because the
graph of the function has intercepts at (-4,0) and (0,
-2).
C. f(x) has no real zeros because the graph of the
function does not pass through (0,0).
D. f(x) has one real zero at 4 because the graph of the
function has an intercept at (-4, 0).
Answer:
D.f(x) has one real zero at 4 because the graph of the function has an intercept at (-4,0).

A student says that if 5x2 = 20, then x must be
equal to 2. Do
you agree or disagree with the
student? Justify your answer.
Answer:
I agree with the student's answer. "x" cannot be -2 because then it would make -20 which is not equal to 20:
5(-2)(2) = ?
-10 x 2 = ?
? = -20
-20 ≠ 20
Step-by-step explanation:
Justificaiton:
5(x)(2) = 20
10(x) = 20
10/10(x) = 20/10
x = 2
Second Justification:
5(x)(2) = 20
5/5(x)(2) = 20/5
2x = 4
2x/2 = 4/2
x = 2

Answer:
The linear speed is
Step-by-step explanation:
step 1
Find the circumference of the circle
The circumference is equal to
we have
substitute
step 2
Find the linear speed in feet per minute
we know that
The wheel is rotating at 10 revolutions per minute
Convert revolutions to feet
Remember that
One revolution is equal to the circumference of the circle
so
10 revolutions is equal to
therefore
The linear speed is

Answer:120 degrees
Step-by-step explanation:
Take 9 numbers forming a calendar and mark 4 number corner. Add the square of diagonal pair and difference of the sum
A triangle has side lengths of (7n-2p) centimeters, (2n+4q) centimeters, and (q-5p) centimeters. Which expression represents the perimeter, in centimeters, of the triangle?
Answer:
It is 9n - 7p + 5q
Step-by-step explanation:
Perimeter formular:
[tex]perimeter = (side + side + side)[/tex]
substitute:
[tex]p = \{(7n - 2p) + (2n + 4q) + (q - 5p) \} \\ [/tex]
group like terms together:
[tex] = (7n + 2n) + ( - 2p - 5p) + (4q + q) \\ = 9n - 7p + 5q[/tex]
Find the sum of the even numbers from 1 to 300
a) 14,280
b) 22,650
c) 16,100
d) 15,460
Answer:
The answer is 22,650
So, option b for you
Step-by-step explanation:
To find the sum of even numbers from 2 to 300, the formula we use is,
N ( N + 1 )
Where N is given by,
N = [( first number + last number)/2] - 1
So here, N = [ (2 + 300 ) / 2 ] - 1 = 150
And hence Sum = 150 * 151 = 22650

Three times the sum of a number and 2 is the same as three-fifths of the sum of the same
number and 22. What is the number?
Answer:
3
Step-by-step explanation:
3(n+2)=3/5(n+22)
3n+6=3/5n+66/5
3n-3/5n = 66/5 - 6
2.4n = 7.2
n = 7.2/2.4
n = 3
Students in Ms. Bell’s geometry class created posters of geometric definitions. Which of the following is the most precise definition?
A. Parallel lines are lines that do not intersect.
B. A line segment is part of a line that has an endpoint.
C. Perpendicular lines are lines that intersect at a right angle.
D. An angle is formed by two lines, two segments or two rays in one plane.
Answer:
C
Step-by-step explanation:
D is missing 2 ideas.
An angle can be formed by a mixture of the types of figures quoted.An angle has common or shared endpoint.B: to me is unclear. A line does not have an endpoint. A ray does.
A: you need to mention that the lines are coplanar.
I think, brief though it is, C is the most complete and at the same time simplest choice.
Suppose an ATM PIN must consist of 6 numbers from the digits 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9, with repeats allowed. For example, an acceptable PIN could be 955123.

2. If someone had one attempt to guess an ATM PIN, what is the probability they would guess correctly with one attempt?
Answer:
1) the no. of possible pins are 6×5×4×3×2×1
=720
2) the probability is 1/720
In a competitive examination negative marks of 2 are awarded for each wrong answers and 4 marks for every correct answer. If neerav gets 15 correct answers and 5 wrong answers and rajan gets 14 correct answers and no wrong answers, who gets more marks and by how much?
9514 1404 393
Answer:
Rajan gets 6 marks more
Step-by-step explanation:
Neerav's marks are (15)(4) +(5)(-2) = 60 -10 = 50.
Rajan's marks are (14)(4) = 56.
Rajan gets 6 more marks than Neerav.
