Which of the following best defines 2 2/3?

inna [77]

Answer:

A. $\sqrt[3]{4}$ = Cube root of 4.

Step-by-step explanation:

We have been given an expression $2^{\frac{2}{3}}$ . We are asked to find the equivalent expression for our given expression.

Using exponent property $\sqrt[n]{a^m} =a^{\frac{m}{n}$ , we will get,

$2^{\frac{2}{3}}=\sqrt[3]{2^2}$

$2^{\frac{2}{3}}=\sqrt[3]{4}$

Upon looking at our given choices, we can see that option A is the correct choice.

4x+(-3)=-2x-5 could someone help me solve this?

lions [1.4K]

4x+(-3)=-2x-5

4x-3 = -2x-5

add 2x to each side

6x-3 =-5

add 3 to each side

6x = -2

divide by 6

x = -2/6

divide top and bottom by 2

x = -1/3

Tony took a math quiz last week. There were 80 problems on the quiz and Tony answered 70% of them correctly. How many problems d

Nutka1998 [239]

Answer:

56 problems

Step-by-step explanation:

So we already know that the answer is: 56. However, a good help is knowing how to obtain this answer from the data provided.

Tony's quiz had 80 questions

Tony correctly answered 70% of them.

We can always write a percentage amount as a ratio by dividing the amount by 100.

$70\% = \frac{70}{100} = 0.7$ .

This means that for every 100 questions, tony will respond correctly 70.

So, if Toni did a questionnaire of n questions, the amount that will answer correctly is calculated by the following expression:

$C = n*\frac{70}{100}$

If $n = 80$ then:

$C = 80 * \frac{70}{100}\\\\C = 56$

Quadrilateral ABCD is transformed to create A′B′C′D′. Match the coordinates of A′ with the transformations that create it.

bulgar [2K]

Answer:

The answer is below

Step-by-step explanation:

From the image attached, the coordinates of point A is at (2, -4).

Transformation is the movement of a point from its initial location to a new position. Types of transformation include dilation, reflection, translation and rotation.

If a point A(x, y) is reflected over the x axis, the new point is at A'(x, -y)

If a point A(x, y) is translated a units right and b units down, the new location is at A'(x + a, y - b)

If a point A(x, y) is dilated by factor of a, the new location is at A'(ax, ay)

If a point A(x, y) is rotated 180° clockwise about the origin, the new location is at A'(-x, -y)

Hence:

For Quadrilateral ABCD is reflected over the x-axis, the coordinates of A' is at A'(2, 4)

For Quadrilateral ABCD is translated 2 units right and 1 unit down, the coordinates of A' is at A'(4, -5)

For Quadrilateral ABCD is dilated by a scale factor of 3, the coordinates of A' is at A'(6, -12)

For Quadrilateral ABCD is rotated 180° clockwise about the origin the coordinates of A' is at A'(-2, 4).
