Which of the following could be the side measures of a right triangle?
A. 6 ft, 5 ft, 4 ft
B. 8 ft, 7 ft, 6 ft
C. 10 ft, 8 ft, 6 ft
D. 12 ft, 10 ft, 8 ft
Answer:
C
Step-by-step explanation:
First, let us try the first on:
sqrt (5^2+4^2)=sqrt 41 so it can't be A
Second one:
sqrt (6^2+7^2)=sqrt 85, no
Third one:
sqrt (8^2+6^2)=sqrt 100 = 10, so it is C
Answer:
C
Step-by-step explanation:
I will just say how to do C but it is the same for all of the other ones.
First I write a²+b²=c²
Then I put in the numbers and get 6²+8²=10²
After that I do the ² to all of them to get 36+64=100
Next I add 64 and 36, which equals 100
100=100

IF YOU DONT KNOW THE ANSWERS DONT ANSWER!! ANSWER ALL QUESTIONS 1-5!!
Answer:
D, A, A, B, CStep-by-step explanation:
1.
P(odd) = 3/6 = 1/2
P(blue) = 1/5
P(odd and blue) = 1/2*1/5 = 1/10
2.
Possible outcomes are 9 as all non-zero digits. And 8 is one of them.
P(8) = 1/9
3.
Non-zero digits: 1, 2, 3, 4, 5, 6, 7, 8, 9
5 of them are odd and 4 of them are even.
One digit is discounted as can't repeat and 4 out of remaining 8 are even.
P(even) = 4/8 = 1/2
4.
Remaining marbles: 2 orange, 3 black, 4 pink. Total 9
P(pink) = 4/9
5.
Each spinner has 3 colors.
P(red or orange) = 2/3
P(both red or orange) = 2/3*2/3 = 4/9

what is 2/3 of 16 (please and thank you)
Answer:
_
10.6
hope dis helps ^-^
The requried value of 2/3 fraction of 16 is 10 and 2/3, or approximately 10.67.
To find 2/3 of 16, you can multiply 16 by the fraction 2/3:
(2/3) * 16 = (2 * 16) / 3
Now, calculate the numerator:
2 * 16 = 32
So, the result is:
(2/3) * 16 = 32 / 3
Next, simplify the fraction:
(2/3) * 16 = 10 and 2/3 or 10.67 (rounded to two decimal places)
Therefore, 2/3 of 16 is 10 and 2/3, or approximately 10.67.

Can you share a strategy For multiplying?
Answer:
Step-by-step explanation:
It's like the same thing for adding. For example if you have 3 x 4. You can add 3 four times or you can add 4 three times. Like this.
3 + 3 + 3 + 3 = 12 because you know 3 + 3 =6 and 6 + 6 equals 12.
OR
4 + 4 + 4 = 12 because you know 4 + 4 = 8 and 8 + 4 equals 12.

some tomatoes that
weigh t pounds. How
Tomatoes
$3.25 per lb
much will it cost to
buy a watermelon that
weighs 182 pounds
and 5 pounds of
tomatoes?
Pt. 2 - How much will it all cost?
Answer:
The answer is that the cost will be a total of $142.05. That is $125.80 for Watermelon that weighs 185 lbs and $16.25 for 5 lbs of tomatoes.
Step-by-step explanation:
Given: Watermelons are .68 / lb and tomatoes are 3.25 / lb.
Let w = watermelon weight and tomato weight.
An equation would be:
.68w + 3.25t = Total cost
For 185 lb of Watermelon and 5 lbs of tomatoes:
.68(185) + 3.25(5) =
$125.80 + $16.25 = $142.05

Shaquille, Lyle, and Amanda collect stamps. Shaquille has one-half the number of stamps that Lyle has. Amanda has two-thirds as many stamps as Lyle. Together they have 364 stamps. How many stamps does Amanda own?
Answer:
Amanda has 112 stamps
proof:
Lyle has 168 stamps
Shaq has 84 stamps
Step-by-step explanation:
S = number of stamps Shaquille has
L = number Lyle has
A = number Amanda has
S = 1/2L
A = 2/3L
S + L + A = 364
substituting for S and A
1/2L + L + 2/3L = 364
reduce
2 1/6L = 364
divide both sides by 2 1/6
L = 168
S = 1/2(168) = 84
A = 2/3(168) = 112

What is the answer for 4y-46+y=4-5y+10 ?
Answer:
y = 6
Step-by-step explanation:
4y - 46 + y = 4 - 5y + 10
simplify
5y - 46 = 14 - 5y
add 5 y to each side
10y - 46 = 14
add 46 to each side
10y = 60
divide both sides by 10
y = 6
HELP WILL GRIVE BRAIN 100 POINTS PLEASE ANSWER ALL 5
Answer:
1. The sum of 4 and x is 7, and to isolate the variable, you move the 4 to the other side and the equation will change into x=7-4, giving us x = 3
2. To solve this inequality, you must isolate the variable x by moving -9 to the other side. To do this, you have to divide 27 by -9, and this causes the direction of the inequality sign to change. After you divide, the inequality changes to this: x<-3
3. since there are no negative numbers involved in this inequality, you divide 3 by 1/4 (or multiply it by 4) to isolate x. this gives us x <= -12
4. To solve this algebraic equation, you must isolate the variable 3x. To do this, you must move -9 to the other side of the equation by adding 9 to the 6. this gives us 3x=15 and x = 5
5. To put x by itself, you subtract 1 by 4, giving you x<-3
