Answer:
x = 5
Step-by-step explanation:
Set up proportion and cross multiply to solve:
9/2x-1 = 15/3x
x = 5
Answer:
Step-by-step explanation:
An angle bisector divides the base into ratios obtained by the sides of the triangle that are not divided. So
9/(2x - 1) = 15/3x Divide 3 into 15
9/(2x - 1) = 5/x Cross multiply
9x = 5(2x - 1) Remove the brackets
9x = 10x - 5 Switch sides.
10x - 5 = 9x Subtract 9x from both sides
10x - 9x - 5 = 0 Combine
x - 5 = 0 Add 5 to both sides.
x = 5

how does the graph of g(x) = (x - 3)^3 - 2 differ from the group of f(x) = x^3?
A. g is shifted 3 units right and 2 units up.
B. g is shifted 3 units right and 2 units down.
C. g is reflected across the y-axis.
D. g is rotated 90* clockwise.
Answer:
B
Step-by-step explanation:
f(x) = x³
g(x) = (x - 3)³ - 2
The inside of the parenthesis represents a horizontal shift
If the number operation being done to x inside of the parenthesis is adding ( or if the number is positive ) then the graph will shift to the left. If the operation being done inside of the parenthesis to x is subtraction ( or if the number is negative ) then the graph will shift to the right.
The operation being done is subtraction therefore it will shift to the right. So it will go 3 units to the right.
the number on the outside works like a y intercept. if it's positive it goes up, if it's negative it goes down. the number is -2 so it will go down 2 units
we can conclude that g is shifted 3 units right and 2 units down
the answer is B

Pankaj borrows rupees 57,000 to buy a used car and is charged the rate of interest 6% per annum. if the term of his borrowing is 4 years, how much interest does he pay?
Rs.13680 is the answer.
Step-by-step explanation:-
Given-
• Principal (P) = Rs.57,000
• Rate (r%) = 6%
[tex]→ \frac{6}{100} [/tex]
[tex]→ 0.06[/tex]
• Time (n) = 4 years
Applying Interest formula,
[tex]→In=P \times R \times T[/tex]
[tex]→57,000 \times 0.06 \times 4[/tex]
[tex]→Rs.13680[/tex]
Hence, the interest is Rs.13680

1) How do you find the sum of the exterior angle measures of any convex polygon?
2) If the polygon is regular, how do you find the measure of each exterior angle in the polygon?
Answer:
1) sum of all convex polygons' EXTERIOR ANGLES IS ALWAYS 360 DEGREES. If it is a triangle or even if it is a 25- gon.
2) if the polygon is regular then this means all of the sides are equal and all of the angles are equal to each other.
for example: Find the measure of an exterior angle of a REGULAR HEXAGON. so a regular hexagon has 6 sides all the same length and 6 exterior angles all the same measures. so to find the measure of 1 exterior angle you do 360 degrees /6 = 60 degrees. so an exterior angle of a regular hexagon is 60 degrees.

Answer:
It would take 8 hours
as 7+9÷2 will give 16
average time will be 8 hrs
Answer:
3.9
Step-by-step explanation:
Let's do this. Sally can paint 1/7 of the room in an hour while Steve can paint 1/9 of the room in an hour. 1/7+1/9 = 16/63. Two of them working together can paint 16/63 of a room in an hour. Now, let's divide 63 by 16.
Use a calculator from here.
63/16 = 3.9375
3.9375 rounded to one decimal place would be 3.9 and not 4, since the next number after 9, which is 3, is not up to 5. If it were 5 to 9, then the answer would be 4.

An angle measures 52.8 degrees more than the measure of its supplementary angle. what is the measure of each angle?
Answer: 116.4 and 63.6 degrees
Step-by-step explanation:
Let the angle be x, so supplement is 180-x.
This means x - 52.8 = 180 - x
2x = 232.8
x = 116.4
So the angle measures are 116.4 and 63.6 degrees

probability (a) = 25%
probability (b) = 60%
determine probability (a and b)
Answer:
85%
Step-by-step explanation:
P(a) = 25%=1/4
P(b) = 60%=3/5
P(a and b) = 1/4 + 3/5 = 5+12/20 = 17/20 = 85%
Answer:
The probability of A and B is 85%
Step-by-step explanation:
It is 85% because 25% is 0.25 or 25/100(1/4), and 60% is 0.6 or 6/10(3/5). 0.6+0.25=0.85 and to convert it back to a percentage you need to times 100%. 0.85x100%=0.85x100 with a percentage symbol =85%.

Answer:
x = ln (y)
Step-by-step explanation:
There's two main ways to solve this. When there is no logarithm in the equation you can either take the log of both sides OR change an exponential equation to logarithmic form.
See image.
note: log_2 (2) = 1
log_3 (3) = 1
log_4 (4) = 1
log_5 (5) = 1
if the base and the article are the same then it equals 1
ln e = 1
because ln e means the same thing as log_e
log_e (e) = 1
e is just a number!
If you are changing exponential form to logarithmic form, the base is the same in both forms. The base is the base. The base in exponential form is the base in logarithmic form. The base is the base. The exponent and article basically switch places to change forms.

Cara and Amber have saved $43. Amber has saved $3
more than 3 times the amount Cara has saved. How
much money has each girl saved?
Let the amount Cara has is X
Amber has 3x +3
Together they have 43:
3x +3 + x = 43
Simplify:
4x +3 = 43Subtract 3 from both sides:
4x = 40
Divide both sides by 4:
x = 10
Cara has $10 and Amber has $33
Answer:
Cara saved $43 and Amber saved $132.
Step-by-step explanation: 3+3(43)=132

Question in image*
Ray hired a moving company to help him move to a new apartment. The equation below.
represents the relationship between the number of hours it takes to move (x) and the total cost
to move (y).
- 100 = 240x - 2y
What is the cost per hour?
Answer:
$120/hr
Step-by-step explanation:
if x is hours to move and y is total cost, let's rearrange the equation so that it is easier to understand. I'd say isolate y (total cost) and see what it is equal to:
- 100 = 240x - 2y
2y = 240x + 100
y = 120x + 100
What I see is: Total Cost = 240*(Hours to move) + 100
That tells us that each hour is $120. It also discloses that there appears to be an upfront charge of $100, before any work is done( even at 0 hours). [If the movers come to the apartment, but you've changed your mind, then it still costs $100].
It also tells us that the charge per hour is $120. [If I had a pickup, I'd do it for $100/hour, but my tiny Honda Accord trunk barely holds the spare tire.]
a^2 - ba +ac -cb factorize
Answer:
[tex](a-b)(a+c)[/tex]
Step-by-step explanation:
Factor each half of the expression separately:
[tex]a^2-ba+ac-cb\\a(a-b)+c(a-b)[/tex]
Since both a and c are being multiplied by a-b, we can combine them to get:
[tex](a-b)(a+c)[/tex]
