answer 13/17

Step-by-step explanation:

you add all the numbers up in the table, which would be 34 and then add up the ones that are big and the ones that are purple, which would be 26 so 26/34 then you simplify.

so 26/34=13/17

Answer:

12/17

Step-by-step explanation:

total number of marbles that are purple (11) plus the total number of marbles that are not small (15) minus the number of marbles that are both purple and not small (2)

11 + 15 - 2 = 24

over the total number of marbles (34)

24/34 simplifies to 12/17

Which best explains whether a triangle with side lengths 5 cm, 13 cm, and 12 cm, is a right triangle?

Llana [10]

The Pythagorean Proposition can help you explain this:
${a}^{2} = {b}^{2} + {c}^{2} \\ {13}^{2} = {5}^{2} + {12}^{2} \\ 169 = 25 + 144$

The equation of a line is y = 17x -6

julia-pushkina [17]

Answer:

(0, -6)

Step-by-step explanation:

the point where the line crosses the y-axis has its x value = 0.

hence y = 17 * 0 -6 = -6

so (0, -6)

A pipe is 30 feet long. it need to be cut into pieces that are each 2/3 ft long how many pieces can be made from the pipe? answe

AysviL [449]

Answer:

Divide total length by length of each piece to get the number of pieces.

= 30 ÷ 2/3

multiply by reciprocal of 2/3

= 30 * 3/2

= 90/2

= 45

ANSWER: Total number of pieces that can be cut is 45.

Exercise

Maurinko [17]

X - nominator
y - denominator

$\frac{3x}{y+12}=\frac{3}{4}\\
\frac{x+7}{3y}=\frac{1}{2}\\\\
3(y+12)=12x\\
2(x+7)=3y\\\\
3y+36=12x\\
2x+14=3y\\\\
2x+14+36=12x\\
10x=50\\
x=5\\\\
3y=2\cdot5+14\\
3y=10+14\\
3y=24\\
y=8\\\\
\frac{x}{y}=\boxed{\frac{5}{8}}$

WILL GIVE BRAINLIEST!!!

Slav-nsk [51]

$\text{Consider the function}\\
\\
f(x)=6x^3-3\\
\\
\text{let }y=f(x), \text{ so we have}\\
\\
y=6x^3-3\\
\\
\text{now in order to find the inverse of the function, first we interchange x and y}\\
\text{so we get}\\
\\
x=6y^3-3$

$\text{now we will solve for y again and that will give the required inverse function.}\\
\text{so first we add 3 both sides to get}\\
\\
x+3=6y^3\\
\\
\text{now divide both sides by 6 to get}\\
\\
\frac{x+3}{6}=y^3\\
\\
\text{now take cube root both sides to get}\\
\\
\sqrt[3]{\frac{x+3}{6}}=\sqrt[3]{y^3}$

$\Rightarrow \sqrt[3]{\frac{x+3}{6}}=y\\
\\
\Rightarrow y=\sqrt[3]{\frac{x+3}{6}}\\
\\
\text{hence the inverse of the function is: }\\
\\
f^{-1}(x)=\sqrt[3]{\frac{x+3}{6}}$
