Answer:
[tex]\huge\boxed{TS = 10.5}[/tex]
Step-by-step explanation:
Given that:
R is a point lying on line TS
So,
TS = TR + RS
Where TR = 4.5 and RS = 6
=> TS = 4.5 + 6
=> TS = 10.5
Find the perimeter to this irregular shape.
Answer:23 mm
Step-by-step explanation:
add both 15 and 8 because they are as long as the one on the bottom
Answer:
70
Step-by-step explanation:
find the small unknown side by subtracting the two sides across from it. 12-7=5. add the 15 and 8 for the big unknown side. 15+8=23. add all the sides. 12+15+7+8+5+23=70
Given
m2 ABD is a straight angle.
m ABC = 8x - 41°
mZCBD = 9x + 17°
Find m2CBD:
А
B
D
Answer:
∠CBD = 125°
Step-by-step explanation:
The angle sum theorem tells you that ...
∠ABC +∠CBD = ∠ABD
8x -41° +9x +17° = 180° . . . . . . a "straight angle" has a measure of 180°
17x -24° = 180° . . . simpify
17x = 204° . . . . . . add 24°
x = 12° . . . . . . . . . . divide by 17
Now the measures of the angles can be found from their expressions.
∠ABC = 8(12) -41° = 55°
∠CBD = 9(12) +17° = 125°

5x-6y=17 whats the value of y?
Answer:
see below
Step-by-step explanation:
5x - 6y = 17
5x - 17 - 6y = 0
5x - 17 = 6y
y = [tex]\frac{5x - 17}{6}[/tex]
Answer:
Hey there!
Original Equation: 5x-6y=17
Subtract 5x: -6y=17-5x
Multiply by -1: 6y=5x-17
Divide by 6: y= [tex]\frac{5x-17}{6}[/tex].

A. Mean: 79; Median: 93
B. Mean: 87; Median: 93
C. Mean: 87; Median: 87
D. Mean: 93; Median: 87
Answer:
C
Step-by-step explanation:
Mean is all the numbers divided by the amount of numbers listed and Median is what ever number is in the middle (when in order of value). when there's not a exact middle number u add the two numbers in the middle and divide it by two
The gravitational potential energy, ‘G’ of an object is directly proportional to its height, ‘h’ above
the surface of Earth. When the object is at a height of 40 meters above Earth, its gravitational
potential energy is 2200 joules. Find
I. An equation connecting G and h.
II. The gravitational potential energy of the object when it is at a height of 22 meters above the
surface of Earth.
III. The height of the object above the surface of Earth when it has a gravitational potential
energy of 3025 joules.
Answer:
see explanation
Step-by-step explanation:
Given that G is directly proportional to h then the equation relating them is
G = kh ← k is the constant of proportion
To find k use the condition h = 40 when G = 2200, then
2200 = 40k ( divide both sides by 40 )
55 = k
1
G = 55h ← equation of proportion
11
When h = 22, then
G = 55 × 22 = 1210 joules
111
When G = 3025, then
3025 = 55h ( divide both sides by 55 )
h = 55 m

Comment on this math
This illustrates a shortcut for multiplying by 9 that can be convenient for mental arithmetic. The idea is to multiply by 10, which just involves adding 0 (or moving the decimal point), then subtract the original number.
You start at (1,0) And move down 2 units and left 4 units where do you end
Answer:
(-3,-2)
Step-by-step explanation:
Starting at the point (1, 0)
Now we move don 2 units (so the y-value reduces in two units) making now the point (1,0-2) which is (1, -2)
then we move to the left 4 units (so the x-value has now to be decreased in 4 units) making the point: (1-4, -2) which is (-3, -2)
Answer:
It would be -2,4.
Step-by-step explanation:
you start at (1,0) and go down 2 to -2 then left 4 you would land on -2,4

Answer:
g(x) = x - 7
Step-by-step explanation:
g(x) is the same as saying "y".
you need to move the y-intercept down 7 units, therefore putting the term - 7 into the expression.
Answer:
g(x) = x-7
Step-by-step explanation:
First find f(x)
f(x) is the function y =x
f(x) = x
g(x) = f(x) + C C < 0 moves it down
We want to move it down 7 units
g(x) = f(x) -7
g(x) = x-7
Solve by factoring:
5x^2 + 19x + 12 = 0
When solving polynomial equations, first set the equation
equal to zero, then check for a Greatest Common Factor.
Since there is no greatest common factor, this will make life a
little bit more difficult because we will have to factor the trinomial.
First, find all possible factors for constant term.
I have listed these in red below.
Make sure to reverse the factors since in each binomial,
the first term is different so we need to reverse the factors.
The factors of 5x² will just be 5x and z.
After finding factors for the constant and the leading
coefficient for your trinomial, we can eliminate some factors.
If you have an odd coefficient on the middle term,
you can eliminate any pairs of even factors.
So the group I crossed out in purple below will be eliminated.
Another strategy is to use factors a little closer together.
So I would go with the 4 and 3 group.
Surely enough, our trinomial does factor with the 4 and 3.
Now set the factored trinomial equal to 0.
Then use zero product property and you have your answer.
Answer:
-0.27
Step-by-step explanation:
5x^2=25x
25x+19x=44x
44x+12=0
-12=0-12
44x=-12
44x/44=-12/44
x=-0.27

-8 - x = x - 4x
what is x?
Answer:
[tex] \boxed{ \bold{ \huge{\boxed{ \sf{x = 4}}}}}[/tex]
Step-by-step explanation:
[tex] \sf{ - 8 - x = x - 4x}[/tex]
Collect like terms
⇒[tex] \sf{ - 8 - x = - 3x}[/tex]
Move 3x to left hand side and change it's sign
Similarly, move 8 to right hand side and change it's sign
⇒[tex] \sf{ - x + 3x = 8}[/tex]
Collect like terms
⇒[tex] \sf{2x = 8}[/tex]
Divide both sides of the equation by 2
⇒[tex] \sf{ \frac{2x}{2} = \frac{8}{2} }[/tex]
Calculate

The table lists the test scores William and Andre received on five math assessments. Which student had the higher median? By how much? A: Andre by 7 points B: William by 5 points C: William by 7 points D: Andre by 5 points
Answer: c
First you organize the numbers into order then you find the middle of both. The middle of Williams was 89. Then you do the same for Andres and you get 82. To get the difference of them both you have to subtract both of them to get 7 and that’s c.

Answer:
The mistake she made was ; She didn't change the sign when subtracting -3/4 from both sides
She wrote 5/4+3/4 instead of 5/4-3/4
Step-by-step explanation:
Correct solution:
[tex] \frac{3}{4} + m = \frac{5}{4} [/tex]
Subtract-3/4 from both sides
[tex] \frac{3}{4} - \frac{3}{4} + m = \frac{5}{4} - \frac{3}{4} [/tex]
Simplify
[tex]m = \frac{5}{4} - \frac{3}{4} \\ m = \frac{1}{2} [/tex]
The mistake Angela made was when she subtracted -3/4 from both sides, she didn't change the sign and She wrote 5/4 + 3/4 instead of 5/4-3/4.
What are Arithmetic operations?Arithmetic operations can also be specified by the subtract, divide, and multiply built-in functions.
The operator that performs the arithmetic operations are called arithmetic operators.
Operators which let do a basic mathematical calculation
+ Addition operation: Adds values on either side of the operator.
For example 4 + 2 = 6
- Subtraction operation: Subtracts the right-hand operand from the left-hand operand.
for example 4 -2 = 2
We have given the expression as
⇒ 3/4 + m = 5/4
The mistake Angela made was when she subtracted -3/4 from both sides, she didn't change the sign.
She wrote 5/4 + 3/4 instead of 5/4-3/4
Here is the correct work :
Subtract 3/4 from both sides from the equation,
⇒ 3/4 + m - 3/4 = 5/4 - 3/4
⇒ m = (5 - 3)/4
⇒ m = 2/4
⇒ m = 1/2

I need help with math! I don't understand it. Can someone show me step by step.
Answer:
7) refer to d=rt triangle so answer is t= d/r
8) rearrange by dividing so it should be PV/nR = T
9) move 5r to other side which become 2p = q - 5r then divide by 2. final answer is p = q-5r/2
10) multiply both side by b/1 so b got cancel on left side
right side become c(b/1) which is same as cb
then you divide both side by c to isolate b on the right side
