Answer:
12
Step-by-step explanation:
SOLUTION:
In a right triangle, the sum of the squares of the
lengths of the legs is equal to the square of the length
of the hypotenuse. The length of the hypotenuse is 13
and the lengths of the legs are 5 and x.
Hello I need help in my math
12: {x,y,z} ? {a,b,c} is it equal or not?
13: {0} ? { } equal or not?
Please help no spam no links I need help mark brainliest!!
12: Equal, because the cardinal number of {x,y,z} are same as {a,b,c}, that is, 3.
13: Not equal, because in set {0}, there is one element , while in set { } , there are no elements at all .
Hope it helps you. Have a nice day!

For what values of k will the equation 4x² + 8x + k = 0 have two real solutions?
Answer:
k < 4
Step-by-step explanation:
Given a quadratic equation in standard form
ax² + bx + c = 0 ( a ≠ 0 )
Then the discriminant Δ = b² - 4ac informs us about the nature of the solutions.
• If b² - 4ac > 0 then 2 real and distinct solutions
• If b² - 4ac = 0 then 1 real and repeated solution
• If b² - 4ac < 0 then no real solutions
4x² + 8x + k = 0 ← is in standard form
with a = 4, b = 8 , c = k , then
b² - 4ac = 8² - (4 × 4 × k) = 64 - 16k
For two real solutions
64 - 16k > 0 ( subtract 64 from both sides )
- 16k > - 64
Divide both sides by - 16, reversing the symbol as a result of dividing by a negative quantity.
k < 4
Then any value less than 4 will ensure the equation has two real solutions

It took Emma 3/4 hour to rake the leaves. It took her 1/5 hour more to
weed the garden than it took to rake the leaves. It took her 0.2 hour
more to mow the lawn than it took to weed the garden. Discuss a
strategy you can use to find the answer. Then determine how long it
took her to do all three chores.
9514 1404 393
Answer:
total: 2.85 hours = 2 17/20 hours
Step-by-step explanation:
Strategy: convert all fractions to decimals, determine weeding and mowing times, and add the three times to find the total.
3/4 = 0.75
1/5 = 0.2
Solution:
raking time: 0.75 hours
weeding time: 0.75 +0.2 = 0.95 hours
mowing time: 0.95 +0.2 = 1.15 hours
__
Total time: 0.75 +0.95 +1.15 = 2.85 hours = 2 17/20 hours
_____
Additional comment
You may recognize that 0.95 is the middle of three equally-spaced values. Then the total will be 3×0.95 = 2.85 hours.

What is the measure of 2x?
Answer:
130 °
....................
Hi! I'm happy to help!
To solve this, we need to first solve for x.
The total of all the interior angles in a quadrilateral (closed, not curved, shape with 4 sides) is 360°. So, we can single out the xs by subtracting the other angles.
360-89
271
271-76
195
Now that we know that, without the other two angles, the quadrilateral is worth 195. The only 2 angles left have x in them. Since there are 3 xs, we can use this to find out our x.
3x=195
Now, divide both sides by 3.
x=65
Now that we have the value of x, the measure of 2x will just be double that.
65×2
130
The measure of 2x is 130°

1. If a is a subset to B and B is the subset of A, what Else is true about sets A and B
2. List all of the the subsets of {a,b,c}
3. How many subsets are there of {a,b,c,d,e,f}
Answer:
Step-by-step explanation:
1. If A is a subset of B and B is a subset of A then A and B must be equal.
2. The subsets of {a,b,c} are
{ } (emptyset}, {a}, {b}, {c}, {a,b}, {a,c}, {b,c}, {a,b,c}
3} Since {a,b,c,d,e,f} has 6 elements then there are [tex]2^6[/tex] subsets.

Answer:
1. -4/7
2. 4/3
3. x^2 + 16x + 63
4. x^2 + 19x + 90
Step-by-step explanation:
1. (1, 8) and (8, 4)
slope = m = (8 - 4)/(1 - 8) = -4/7
2. (2, 4) and (5, 8)
slope = m = (8 - 4)/(5 - 2) = 4/3
3. (x + 9)(x + 7) =
= x^2 + 7x + 9x + 63
= x^2 + 16x + 63
4. (x + 10)(x + 9) =
= x^2 + 9x + 10x + 90
= x^2 + 19x + 90

7(x + 1) = 1 – 2(5 – x)
? ]
W
Answer:
-16/5
Step-by-step explanation:
7(x+1)=1-2(5-x)
7x+7=1-10+2x
7x-2x=1-10-7
5x = -16
x = -16/5
Answer: [tex]\huge {x = -\frac{16}{5} }[/tex]
Step-by-step explanation:
Given equation
7 (x + 1) = 1 - 2 (5 - x)
Expand parentheses and apply the distributive property
7x + 7 = 1 - 10 + 2x
Combine like terms
7x + 7 = -9 + 2x
Subtract 2x on both sides
7x + 7 - 2x = -9 + 2x - 2x
5x + 7 = -9
Subtract 7 on both sides
5x + 7 - 7 = -9 - 7
5x = -16
Divide 5 on both sides
5x / 5 = -16 / 5
[tex]\boxed{x=-\frac{16}{5} }[/tex]

Nora has a flower arrangement with 7 pink flowers, 9 purple
flowers, and 5 white flowers. Which sentence is not true?
The ratio of total flowers to pink flowers is 21: 7
The ratio of white
flowers to purple flowers is 5:9.
The ratio of purple flowers to total flowers is 16 to 21.
Answer:
The ratio of purple flowers to total flowers is 16 to 21 is NOT TRUE because your total is already 21 so it would make no sense for 16 to be in the ratio
