Step-by-step explanation:
Point B splits a segment AC with ratio AB:BC=2:1. Point D splits a segment AB with the ratio AD:DB=3:2. What is the ratio for AD:DC?
Answer:
The ratio for AD:DC is 2:3
Step-by-step explanation:
The given information are;
The ratio by which point B splits AC as AB:BC = 2:1
The ratio by which point D splits AB as AD:DB = 3:2
Therefore, we have;
The fraction of AC that is equal to AB is given as follows;
AB = 2/(2 + 1) × AC = 2/3 × AC
AB = 2/3 × AC
Similarly
BC = 1/3 × AC
Also the fraction of AB that is equal to AD is given as follows;
AD = 3/(3 + 2) × AB = 3/5 × AB
AD = 3/5 × AB
Therefore, the fraction of AC that is equal to AD is given as follows;
AD = 3/5 × AB = 3/5 × 2/3 × AC = 2/5 × AC
Therefore, DC = (1 - 2/5) × AC = 3/5 × AC
Which gives the ration of AD to DC or AD:DC as being;
AD:DC = 2/5 × AC : 3/5 × AC = 2/5:3/5 = 2:3
The ratio for AD:DC = 2:3.

What is scientific notation
Scientific notation is a way of expression really large or really small numbers.
For instance, 1000000 in scientific notation would be 1 x 10^6
Answer:
Scientific notation is way of writing very small or very large numbers. A number is written in scientific notation when a number between 1 and 10 is multiplied by a power of 10.

Rearrange 2y = 3(2+x) make x the subject
Answer:
[tex]x =\frac{(2y-6)}{3}[/tex]
Step-by-step explanation:
2y = 3(2+x) {Use distributive rule}
2y = 3*2 + 3*x
2y = 6 + 3x {Subtract 3 form both sides}
2y - 6 = 3x {Divide both sides by 3}
[tex]\frac{(2y-6)}{3}=x[/tex]

Which is the better buy? 3-yard roll of butcher paper for $2.88 OR 18-ft roll of butcher paper for $11.52
Answer:
18-ft.
Step-by-step explanation:
WHEW. Just buy it for 11.52. If you bought 18 yd of butcher paper from the 3 yd roll you would be spending almost 52 dollars!
Answer: 3-Yard roll or butcher paper
Step-by-step explanation:
3 Yards = 9 Feet. 3 yards is half of 18 feet. And the cost of 3 yards is only 2.88, And since it is half of the amount of 18 feet, we multiply by two. ($5.76). Meaning 3 Yards is better to buy.
Convert 26 feet to inches:

If PR=40, what are PQ and RQ
Answer:
PQ = 23, QR = 17
Step-by-step explanation:
PR = PQ + QR = 40
Substitute PR and QR into the equation above
40 = 5x - 2 + x + 12
Combine like terms
40 = 6x + 10
Subtract 10 from both sides
30 = 6x
Divide both sides by 6
5 = x
PQ = 5x - 2= 5(5) - 2 = 23
Remember, PR = PQ + QR
40 = 23 + QR
Subtract 23 from both sides.
17 = QR
PQ = 23
Point G is on line segment FH. Given FH = 19 and FG = 12,
determine the length GH.
Answer:
7
Step-by-step explanation:
Let’s think about this like a number line.
If we have a number line with the ends of F and H, and G is somewhere in between, it would look something like this.
F———-G———H
We know that FH = 19 and that FG is 12.
This means that GH will be the FH - FG
[tex]19 - 12 = 7[/tex]
So FG is 7.

Solve for Y: when X = 6
y = -3x +2
Answer:
Y=-16
Step-by-step explanation:
-3(6)+3
-18+2
y=-16
Answer:
-16
Step-by-step explanation:
We can evaluate y = -3x + 2 for x = 6. Substituting 6 for x in y = -3x +2, we get:
y = -3(6) + 2 = -18 + 2 = -16
The equation y = -3x + 2 has already been "solved" for y. At this point you are evaluating this equation at x = 6.

3(2z−4)=−6(2−z). help plss
Answer: (6z-12) = (-12+6z)
Step-by-step explanation:
Okay, so what you want to do is multiply 3(2z-4) and you should get (6z-12). Then you do the exact same thing on the other side, -6(2-z), and you should get (-12+6z). Then you put those together, so it would look like (6z-12) = (-12+6z).

how do i find the hypotenuse using the pythagorean theorem
Step-by-step explanation:
You multiply the two other sides by itself like 12x12=144 and do that for all the sides that you know then you add up all of the numbers you got from adding like 144 plus 64 equals 208 and then 208 is the hypotenuse.
