The height of the roof will be 9 feet instead of 5 feet. Determine the length, in feet of the diagonal wood beams on the new roof. Find the leg. a^2 + 9^2=13^2
Answer:
√88
Step-by-step explanation:
a^2 + 9^2=13^2
a² = 13² - 9²
a² = 169 - 81
a² = 88
Take square root of both sides
a = √88

Answer: (x, y) --> (x, -y)
Step-by-step explanation:
This is a reflection over the x-axis so its only the y-intercept that changes.
Answer:
its a reflection
Step-by-step explanation:
If it were a rotation, it wouldnt have overlapped.
If it were a translation, It would have been the wrong way up and not overlapping.
When reflected over line x, it will overlap because it stays rigid and does not change shape or size.
hope this helps :)
If y = -5, what is the value of
2y+2
-
4
Answer:
-12
Step-by-step explanation:
Ok so I'm guessing that's a -4 but if its not, please correct me.
y= -5 is going to be plugged into 2y+2-4
This means that 2(-5)+2-4=?
2(-5) is the equivalent to 2 times -5, which is -10 (you solve multiplication first because order of operations)
Now, 2-4=-2
So using this, let's combine both equations!
-10+-2=?
?=-12
It's a lot of steps but they get easier the more you do them <3

What is the definition of the ratio?In mathematics, a ratio is a term used to compare two numbers. It is used to express how large or small an amount is in comparison to another. A ratio compares two quantities by dividing them. The dividend is referred to as the 'antecedent,' while the divisor is referred to as the 'consequent.'For the given question.
Let the number of girls be 'x' = 63.
Let the number of boys be 'y'.
The ratio of girls to boy is 9:7.
Thus,
x/y = 9/7
Boys = ?
y = 7x/9
Put x = 63
y = 7×63/9
y = 49

Determine the value of x
Answer:
I would think it is 8
Step-by-step explanation:
By assuming the triangles are equal to each other in a way that the larger triangle is the smaller triangle's length times 2. For example, one side of the smaller triangle is 11 so times 2 would be the larger triangle's side. So, by dividing 16 by two, you would get 8. Hope this helped and that I did it correctly!

Judy makes 2/5 of a beaded necklace on Monday she makes 3/10 of the necklace on Tuesday she makes 1/5 of the necklace on Wednesday what fraction of the necklace has Judy made so far
Answer: 9/10
Step-by-step explanation:
Fraction of beaded necklace made on Monday = 2/5
Fraction of beaded necklace made on Tuesday = 3/10
Fraction of beaded necklace made on Wednesday = 1/5
Total fraction made would be the addition of the Fractions made from Monday to Wednesday. This would be:
= 2/5 + 3/10 + 1/5
The lowest common multiple of the denominator is 10. Therefore we'll make them have a common denominator.
= 2/5 + 3/10 + 1/5
= 4/10 + 3/10 + 2/10
= 9/10

C. [tex] \dfrac{1}{3x + 1} [/tex]
Step-by-step explanation:
[tex] \dfrac{x + 2}{x^3 + 2x^2 - 9x - 18} \div \dfrac{3x + 1}{x^2 - 9} = [/tex]
Factor all polynomials.
[tex] = \dfrac{x + 2}{x^2(x + 2) -9(x + 2)} \div \dfrac{3x + 1}{(x + 3)(x - 3)} [/tex]
[tex] = \dfrac{x + 2}{(x^2 - 9)(x + 2)} \div \dfrac{3x + 1}{(x + 3)(x - 3)} [/tex]
[tex] = \dfrac{x + 2}{(x + 3)(x - 3)(x + 2)} \div \dfrac{3x + 1}{(x + 3)(x - 3)} [/tex]
To divide by a fraction, multiply by its reciprocal.
[tex] = \dfrac{x + 2}{(x + 3)(x - 3)(x + 2)} \times \dfrac{(x + 3)(x - 3)}{3x + 1} [/tex]
Cancel out common factors in the numerator and denominator.
[tex] = \dfrac{1}{3x + 1} [/tex]
