Rocco is trying to find the fraction that is equivalent to the decimal 0.012. His work is shown below. Step 1: 0.012 = StartFrac

tion 12 over 100 EndFraction Step 2: StartFraction 12 over 100 EndFraction equals StartFraction 3 over 25 EndFraction Step 3: Therefore 0.012 = StartFraction 3 over 25 EndFraction. What did Rocco do wrong? Rocco should have divided 12 by 100 in Step 2. Rocco wrote the equivalent fraction in Step 1 incorrectly. Rocco forgot to reduce the numerator when he reduced the denominator in Step 2. Rocco should have divided both the numerator and denominator by 2, not

Answer:

(B)Rocco wrote the equivalent fraction in Step 1 incorrectly.

Step-by-step explanation:

In trying to find the fraction equivalent of 0.012, Rocco's work is shown below:

Step 1: 0.012 = \dfrac{12}{100}

Step 2:  \dfrac{12}{100}=\dfrac{3}{25}

Step 3: Therefore 0.012  =\dfrac{3}{25}

Observe that in Step 1, Rocco wrote the equivalent fraction incorrectly.

Correctly: 0.012 = \dfrac{12}{1000}

The correct answer is B.

Answer:

Roman

Step-by-step explanation:

An easy way to solve this is looking at whether the line has a positive or negative slope. We read graphs from left to right so <u>if the line is increasing from left to right, it has a positive slope while a line decreasing from left to right has a negative slope</u>. Since the line shown is decreasing from left to right, it will have a negative slope and Roman is the only one out of the two that shows a negative slope. To check to see if he's correct, we can check the y-intercept. The y-intercept of the line is 8 and Roman also has 8 written in the expression. Hence, meaning Roman is correct.

Best of Luck!

Juan put three square tiles with sides 8 centimeters, 10 centimeters, and x centimeters together so that they form a right trian
Elan Coil [88]
Since the area of a square is equal to the square of one of its side's length, then the area should be equivalent to x^{2}.
A = x^{2} ---> equation (1)
By using pythagoras rule which states that the x^{2} = hyp^2 - opposite^2---> equation (2)
where the opposite side's length is 8 and the hypotenuse side's length is 10
by substituting by the values in equation (2) therefore,
x^{2} = 10^{2} - 8^{2} substitute this value in equation (1) then
A = x^{2} = 10^{2} -8^{2}
where A is the area of the square whose side is x

Find the remainder when x4 - 5x3 + x2 - 10x - 5 is divided by x + 3.
m_a_m_a [10]

Use the remainder theorem: we can decompose the given polynomial in terms of quotient and remainder polynomials q(x) and r(x), respectively, such that

x^4 - 5x^3 + x^2 - 10x - 5 = (x + 3) q(x) + r(x)

Then letting x = -3 makes the quotient term vanish, and we're left with a remainder of

r(-3) = (-3)^4 - 5\times(-3)^4 + (-3)^2 - 10\times(-3) - 5 = \boxed{250}

the product of two consecutive even positive integers is 10 more than seven times the larger . find the integers?
Andreas93 [3]
2 consecutive even numbers.....x and x + 2

x(x + 2) = 7(x + 2) + 10
x^2 + 2x = 7x + 14 + 10
x^2 + 2x = 7x + 24
x^2 + 2x - 7x - 24 = 0
x^2 - 5x - 24 = 0
(x - 8)(x + 3) = 0

x - 8 = 0
x = 8

x + 3 = 0
x = -3...not this one because it is negative

x = 8
x + 2 = 8 + 2 = 10

so ur 2 consecutive even numbers are 8 and 10
