The coordinates of the point that makes the division in the given ratio is (0,3)
Step-by-step explanation:
Here, we want to find the point on the line segment that divides the line segment in the ratio 1:2
We simply use the internal division formula
That would be;
(x,y) = (nx1 + mx2)/(m + n) , (ny1 + my2)/(m + n)
m = 1 and n = 2
(x1,y1) = (4,9)
(x2,y2) = (-8,-9)
Substituting these values into the formula, we have;
2(4) + 1(-8)/(1 + 2) , 2(9) + 1(-9)/(2 + 1)
= (8-8)/3 , (18-9)/3
= (0,3)

9 A rectangle of perimeter 42 cm is
pcm long and q cm broad. If the
difference between the length and
breadth is 9 cm. find
pand q
the area of the rectangle
Answer:
The correct answer is = p = 15 and q = 6.
Step-by-step explanation:
Given:
Perimeter of rectangle = 42 cm
p - q = 9 cm
length = p
width = q
we know:
Perimeter of rectangle= 2(l+w)
solution:
42 = 2(P+q)
21= p+q
Difference of p and q = 9 cm.
Then, P+q=21 .... 1
P-q=9 ....2
Adding both 1 and 2
2P = 30
P= 15cm and
q = 15-9
= 6cm
In January, Mr Tan's students read 20 books. In Febuary, they read 15 books. What is the percent increase or decrease in the number of books they read?
A. 5% decrease
B. 15% increase
C. 25% increase
D. 25% decrease
Answer:
D. 25% decrease
Step-by-step explanation:
Since it's clear that they read less books to find how much it decreased we multiply 100 with 15 then divide it by 20
100 × 15 ÷ 20 = 75 this result shows a 25% decrease.

can someone find x for me?
Answer:
Question 4: x = 106
Question 5: x = 118
Step-by-step explanation:
Question 4: The exterior angles of a triangle are going to add up to 360.
128 + 126 = 254
360 - 254 = 106
x = 106
Question 5: The exterior angles of a polygon add up to 360 (a quadrilateral is a polygon).
A right-angle = 90
90 + 34 = 124
360 - 124 = 236
236 / 2 = 118
x = 118
I hope this helps! :)

c. n is 60% of r. How many nickels do you have?
Please help!!
9514 1404 393
Answer:
a. 38
b. 95
c. 57
Step-by-step explanation:
In this context, you can consider "of" to mean "times." It can also be helpful to think of % as meaning /100.
a. p = 20% × 190
p = 20/100 × 190 = 38 . . . . you have 38 pennies
__
b. 190 = 200% × r
190 = 200/100 × r . . . . replace % with /100
190 = 2 × r . . . . . . . . . simplify the fraction
190/2 = r = 95 . . . . you have 95 rare coins
__
c. n = 60% × r
n = 60/100 × 95 = 57 . . . . you have 57 nickels

-x - 21 = 5x
Add 'x' to both sides

B (27, 30)
Point A has coordinates (3, 2)
Point B has coordinates (27, 30)
Point C is marked on the diagram.
Work out the coordinates of C.
Answer:
The coordinates of C are (15,16)
Step-by-step explanation:
As we can see, point C lies half the distance of AB
So we can use the midpoint formula to get the coordinates of C
we have this as:
(x,y) = (x1 + x2)/2 , (y1 + y2)/2
(x1,y1) = (3,2)
(x2,y2) = (27,30)
Thus, we have
(x,y) = (3 + 27)/2, (30 + 2)/2
(x,y) = 30/2 , 32/2
(x,y) = (15,16)
Find the slope-intercept form of an equation of the line perpendicular to the graph of x – 3y = 5 and passing through (0, 6).
Answer:

The smith family went out for dinner the price of the meal was $39.85 the sales tax was 8.1% of the price of the meal the tip was 17% of the meal and the sales tax how much did the smith family pay for the meal including tax and tip PLEASE HELP ILL GIVE LOTS OF POINTS
9514 1404 393
Answer:
$50.40
Step-by-step explanation:
Adding the tax multiplies the amount by 1+8.1% = 1.081.
Adding the tip multiplies the amount by 1+17% = 1.17.
Then the amount with tax and tip is ...
$39.85 × 1.081 × 1.17 = $50.40
The Smith family paid $50.40 for the meal.
Kenji's town voted on a new speed limit. Of the votes received, 39 were in favor of the new speed limit and 13 were opposed. What percentage of the votes were in favor of the new speed limit?
Ik, I'm asking a lot of these but I HATE mathhhhh
Answer:
75%
Step-by-step explanation:
You need to find the total number of votes first. Just add 13 and 39 which would equal 52.
Then divide the number of people in favour by the total number of voters and multiply by a 100 to find the percentage.
39 + 13 = 52
39/52 = 0.75
0.75 x 100 = 75.0

Diego is building a boat dock. The length
of the dock is (X + 8) feet. The width of the
dock is (x + 3) feet. Create 2 equivalent
expressions to represent the perimeter of
the boat dock.
Answer:
(x + 8) + (x + 8) + (x + 3) + (x + 3)
and
4x + 22
Two equivalent expressions to represent the perimeter of the boat dock are P = 2[(X + 8) +(X + 3)] or P = 4X + 22.
What is a perimeter?"A perimeter is a measurement of the outside of a shape. In order to find a perimeter, we have to find the sum of all the sides of the shape."
Given
Length of the dock = (X + 8) feet
Width of the dock = (x + 3) feet
A rectangle have length and width.
So the perimeter of the rectangle is 2(length + width)
Formula to find the perimeter of shape
Perimeter of the shape = Sum of all the sides of the shape
P = (X + 8) +(X + 3) + (X + 8) +(X + 3)
⇒ P = 2[X + 8 +X + 3]
⇒ P = 2[2X + 11]
⇒ P = 4X + 22
Hence, two equivalent expressions to represent the perimeter of the boat dock are P = (X + 8) +(X + 3) + (X + 8) +(X + 3) or P = 4X + 22.
