Step-by-step explanation:
If the line through (-2,4)and ) 5,D)is parallel to the graph of y= 3X +4 find the value of d
Answer:
D = 25
Step-by-step explanation:
For 2 lines to be parallel, they must have the same sloe;
Given the coordinates (-2,4)and (5,D)
Slope = D-4/5-(-2)
Slope = D-4/5+2
Slope = D-4/7
Given the equation y = 3x + 4, comparing to y = mx+b
mx = 3x
m = 3
Hence the slope is 3
Equating the slopes
D-4/7 = 3
D-4 = 3*7
D-4 = 21
D = 21+4
D = 25
Hence the value of D is 25
Use the formula C C = 2pi * r and pi = 3 . 14 to find the circumference of a circle with a radius of 5 meters.
Answer:
Circumference of circle = 31.4 square meter
Step-by-step explanation:
Given:
Radius of a circle = 5 meter
Value of π = 3.14
Find:
Circumference of circle using formula "2πr"
Computation:
Circumference of circle = 2πr
By putting value of 'r' and 'π' in given formula
Circumference of circle = 2(3.14)(5)
Circumference of circle = (6.28)(5)
Circumference of circle = 31.4 square meter
Joe, working alone, takes 8 hours to mow a lawn. Sally, working alone, can mow the same lawn in 6 hours. How long does it take them together to mow the lawn (each using their own seperate mower)?
Answer: 3 3/7 hours
Step-by-step explanation:
you need to find out how much work they can do in an hour.
let x represent the total collaborative work
1/8 + 1/6 = 1/x
3/24 + 4/24 = 1/x
7x = 24
x = 24/7 or 3 3/7 hours (in decimal form this is 3.4286)

Answer:Step-by-step explanation:
properties of parallelograms
PLEASE HELP
Answer:
m∠Q = 109°
m∠QRT = 109°
x = 4
Step-by-step explanation:
1). "Opposite angles of a parallelogram are equal"
By this property,
m∠Q = m∠S = 109°
2). "Opposite sides of a parallelogram are parallel and equal in measure"
By this property,
RQ║ST and diagonal RT is a transversal line.
m∠QRT = ∠SRT = 30° [Alternate interior angles]
3). "Opposite sides of a parallelogram are parallel and equal in measure"

The equation f = v + at represents the final velocity of an object, f, with an initial velocity, v, and an acceleration -
a, over time, t. Which is an equivalent equation solved for a?
Ofv=a
10-v=a
O a
(+v=a
o {+v=a
Answer:
A
Step-by-step explanation:
f = v + at
f - v = at
(f-v)/t = a
Answer:
(f - v) / t = a
Step-by-step explanation:
Solving for the equation for a means taking all integers or values on the other side of the equation for a
To do this we must do it mathematically.
f = v + at
f - v = at
(f - v) / t = a

What is the measure of ∠PCB?
75 degrees
18 degrees
33 degrees
144 degrees
Answer:
3rd Option, 33° = ∠PCB
Step-by-step explanation:
First find the measure of ∠CPB;
∠CPB = 180 - 105
∠CPB = 75
Now we can find the measure of ∠PCB;
180 - (Angle 1 + Angle 2)
180 - (75 + 72)
33 = ∠PCB
Hope this helps!

For every $6 spent at a shop, the owner will donate $2 to charity. The
total amount of money donated to the charity was $56. What is the
least possible amount of money that was spent at the shop?
Answer:
$168
Step-by-step explanation:
Divide $56 by $2
$56 ÷ $2 = 28
Thus $2 was donated 28 times
He donated $2 every time $6 was spent, then
money spent = 28 × $6 = $168
Answer:
$168
Step-by-step explanation:
We have the following ratio
Spent at shop : donated to charity
6:2
we know that
x:56
To solve this we just mulitply 6 by 28 (28 because this is what we mulitplied the two in our original ratio to reach 56)
6*28=168

Answer:
0.512 ; - 0.538
Step-by-step explanation:
Using the standard linear regression relation :
y = bx + c
b slope ; c = intercept ; y = dependent ; x = independent variable.
For finalist between 2004 - 2014 ;
y = 0.024x - 0.328
x = 35
y = 0.024(35) - 0.328
y = 0.512
For finalist between 1990 - 2014 ; with 14 winners ; change in daily circulation :
y = -0.015x - 0.328
x = 14.
y = -0.015(14) - 0.328
y = - 0.538
