Answer:
1280
Step-by-step explanation:
Let x represent the age of the girl then...
Brother: x+2
Sister: 2x
We can use this to set up an equation:
x+x+2+2x=34
Combine like terms
4x+2=34
Subtract 2 from both sides
4x=32
Divide both sides by 4
x=8 (girl)
x+2=10 (brother)
2x=16 (sister)
Now, we multiply these three numbers to get the product of their ages.
8(10)(16)=80(16)=1280

A bag holds 5 red marbles, 7 green marbles, and 4 yellow marbles. If marbles are not returned to thr bag afetr being drawn, what is the rpobability that the first marble will be red and the second marble will be yellow?
A. 1/4
B. 1/12
C. 3/16
D. 4/52
Answer:
1/12
Step-by-step explanation:
Total number of marbles = 5+7+4 = 16 marbles
Probability of picking a red marble = 5/16
Because the red marble is not returned back after being picked up, the total number of marbles is now 15.
Now,
Probability of picking a yellow marble = 4/15
The probability of picking a red and yellow marble will be the product of these two probabilities which will = 5/16 x 4/15 = 1/12

Q10
Answer:
5/4r + 10p
Step-by-step explanation:
Combine like terms
8p + 2p = 10p
1/2r +3/4r = 5/4r
Make 1/2 have the same denominator as 3/4 multiply the top and bottom by 2 and add the fractions.
[tex]\frac{1}{2}[/tex] [tex]\frac{x}{x}[/tex] [tex]\frac{2}{2}[/tex] = [tex]\frac{2}{4}[/tex] + [tex]\frac{3}{4}[/tex] = 5/4
= 5/4r + 10p

Round 1.85 to 1 decimal place
Answer:
1.9
Step-by-step explanation:
1.85 is expressed to 2 decimal places. Since the '5' is ≥ 5, we round 1.85 UP to 1.9.

Answer:
For one of them, it will be B=(4.5, 1.5). The sides would each be 3.54 long.
For the second, B=(1.5,5.5). Lines AB and CB are also going to be 3.54 long.
Step-by-step explanation:
My thought process was all over the place, to be honest with you. I drew out the points on some graph paper and found out the length of AC, which is 5. Then I thought I could use the law of sines since we know that the other two angles are both 45 degrees. Anyways, I got the lengths as 3.5. I was a bit off, but I found that out later. I thought of using a compass to try to see where a point would meet if there is a distance of 3.5, but I don't have a compass, so I went searching for online ones. I couldn't find one with a graph in it, so I used an online graphing system. From the beginning, I knew that it was probably going to be something .5, so I kept on trying to find a spot that had a length of 3.5 on both sides, and got really close, but they were still off. I checked where B was graphed, and it was a really long decimal, so I just put it to .5 on both the y and x and voila, I got 3.54 on both lines AB and CB. I, of course, checked my answers and found that the angle was in fact 90 degrees and I felt very pleased with myself. I did a simpler version for the other angle.
I hope this is correct! Please let me know, this was really fun anyways!

Would someone mind helping me? 20 points for a great and correct answer!
Thank you!
Answer:
Step-by-step explanation:
So basically you have to do the Pythagorean Theorem here.
Which is = a^2 + b^2 = c^2
So you'll put 35 in 'a' and 84 in 'b'
It'll be like this = 35^2 + 84^2 = c^2
So here, we are looking for 'c'
And 'c' is the hypotenuse
So,
Step 1: 35^2 + 84^2 = c^2
Step 2: You will use the exponents (but not for c)
= 1225 + 7056 = c^2
Step 3: You will now add 1225 + 7056 = 8281
Step 4: Now, square root 8281√8281 = 91
91 = c
Hope this helps! Please let me know if you get this correct!
Donald is participating in a fun run to raise money for the West Side Children's Hospital. The run is held at Donald's high school track. The more laps Donald runs around the track, the more money he raises for the hospital.

Answer:
y = x(5)
Step-by-step explanation:
Examples that prove this to be true are:
1(5) = y
y = 5$
2(5) = y
y = 10$
The reason this is correct is that it follows the same pattern on the graph.

2 cars started to move from C and from D, towards one another. The car that starts at point C moves twice as fast as the car that starts at point D. How far from boston will those two cars meet?
Answer:They meet at 92 miles from C or 46 miles from D.
Step-by-step explanation:An object is said to have constant speed if it travels the same distance at the same time. The ratio between the distance x and the time t is the speed and is given by
Solving for x
The car starting from C has double speed as the car starting from D. this means
When both cars meet, they travel these distances
The sum of both distances is x = 256 - 118 = 138 miles.
Or, equivalently
Using the relations of the speeds:
Solving for t
The distance traveled by the car from c is
The distance traveled by the car from d is
There is no reference of where Boston is located, thus we can only refer the distances respect to C or D, as shown above

Answer yes or no to determine whether 15 is divisible by each number:
2
3
4
5
6
9
10
Answer:
2 No
3 Yes 15 is divisible by 3, because 15 ÷ 3 = 5
4 No
5 Yes 15 is divisible by 5, because 15/5=3
9 No
10 No
Step-by-step explanation:
Answer:
No, yes, no, yes, no, no, no
Step-by-step explanation:
If you're looking for a perfect answer, no decimals or anything then this would be the right answer. 15 has the factors or 5, 3, 1 and 15. Technically, 15 is divisable by all these numbers, but the quotient isn't perfect...

a: Using scale, divide the wing dimensions on the graph by 2 then multiply by 192cm
8.125/2 = 4.0625 x 192 = 780 cm
5/2 = 2.5 x 192 = 480 cm
Actual dimensions: 780 cm by 480 cm
Divide by 100 to convert to meters:
780/100 = 7.8 meters
480/100 = 4.8 meters
b: area of a triangle = 1/2 x base x height
area = 1/2 x 480 x 780 = 187,200 square cm
1/2 x 7.8 x 4.8 = 18.72 square meters
i did the dimensions in both cm’s and meters
Answer:
For A i would put 64 because its basically doing the total wing size divided by the number of sides it has.. And for B i havent thought of that yet..

Answer:
1/2 & 1/10
Step-by-step explanation:
Each of three:
15 outcomes have all three digits 1 through 8
So, 15/30 which is 1/2
Fewer than 2 is one or none being effective, i.e one or no digits are 1 through 8
There are only three such outcomes
So, 3/30 = 1/10
