Answers

The exponent 5¹⁵ is equivalent to the given expression 5¹⁰ · 5⁵. The correct answer would be an option (C).

What is an exponent?

The exponent of a number represents the total time required to multiply that number. 8 8 8 may be stated as 83 since 8 is multiplied by itself three times. In this case, 3 is the 'exponent' or 'power' that indicates how many times 8 is multiplied by itself, and 8 is the 'base' that represents the integer being multiplied.

The exponent expression is given as:

5¹⁰ · 5⁵

We have to determine the equivalent exponent to the given expression.

As per the question, we have

5¹⁰ · 5⁵

Simplify using the exponent rule with the same base,

5¹⁰⁺⁵

Adding the powers in the expression, we get

5¹⁵

This exponent is equivalent to the given expression.

A figure is located entirely in the third quadrant. If you reflect it over y = 0. Which quadrant will the resulting figure lie in?​

Answers

Answer: Quadrant 2

=================================================

Explanation:

Check out the diagram below. An example point in the third quadrant is (-2,-5). This quadrant is the southwest quadrant. Reflect the example point over the x axis (aka the line y = 0) and we get (-2,5). This is shown when we go from point A to point B in the diagram.

The reflection rule is [tex](x,y) \to (x,-y)[/tex] showing that only the y coordinate changes from y to -y. If y is negative, then flip to positive, or vice versa. The x coordinate stays the same.

The point started in quadrant 3 and it moves to quadrant 2 after the reflection over the line y = 0.

Side note: all points on the line y = 0 have a y coordinate of 0

Sara is trying to build the number 0.140 with base ten blocks. She has thousandths blocks, hundredths blocks, and NO tenths blocks. How can she represent 0.140?

Answers

Answer:

0.140 is represented using 40 thousandth blocks and 100 hundredth blocks

Step-by-step explanation:

Base 10 blocks are blocks in set of four which can be used together to represent any number. Also base 10 blocks can be used to perform mathematical computations like addition, subtraction, addition, division, area and many more.

We have to represent 0.140 using hundredths and thousandths blocks.

0.140 = 140 × 10⁻³ = 40 × 10⁻³ + 100 × 10⁻²

10⁻³ represents the thousandth block and 10⁻² for the hundredth. Hence:

0.140 = 140 × 10⁻³ = 40 × 10⁻³ + 100 × 10⁻²  = 40 thousandth + 100 hundredth

0.140 is represented using 40 thousandth blocks and 100 hundredth blocks

area of the trapezoid? Show your work.

Answers

Answer:

38.5

Step-by-step explanation:

The area of the trapezoid FGHJ is 33 square units.

Given that, trapezoid FGHJ has vertices at F(2.-3), G(2, 4), H(6,4), and J(19, -3).

We need to find the area of the trapezoid.

What is the formula to find the area of trapezium?

The area of a trapezium is defined as the number of unit squares that can fit into it and it is measured in square units (like cm², m², in², etc). A trapezium is a type of quadrilateral that has one pair of parallel sides(generally referred to as bases). The other pair of sides of a trapezium can be non-parallel and are known as legs. The area of a trapezium is the total space covered by a trapezium in a two-dimensional plane.

The area of a trapezium =1/2 (a+b)×h square units.

Now, area=1/2 (4+17)×6=33 square units

Therefore, the area of the trapezoid FGHJ is 33 square units.

The solution of the equation, (3/2)·(4·x - 2) - 3·x = 5 - (x + 2) is; x = 1.5

What is an equation?

An equation is a mathematical statement indicating equivalence between two expressions.

The equation (3/2)·(4·x - 2) - 3·x = 5 - (x + 2) can be solved step by step as follows;

Distributing the (3/2) on the left hand side, we get; (3/2)·4·x - (3/2)×2 - 3·x = 5 - (x + 2)Simplify the left hand side; 6·x - 3 - 3·x = 5 - (x + 2)Combine like terms on the left hand side; 3·x - 3 = 5 - (x + 2)Distribute the -1 on the right hand side; 3·x - 3 = 5 - x - 2Combine like terms on the right hand side; 3·x - 3 = 3 - xAdd x to both sides; 4·x - 3 = 3Add 3 to both sides; 4·x = 6Divide both sides by 4; x = 6/4

Therefore, the solution of the equation is; x = 6/4, or x = 1.5

A piece of chocolate is 4/5 inch long. Meg lays 4 chocolate pieces end to end in a row. How many inches long is the row of chocolates ( please helpppppp) ( MAP test question)

Answers

Answer:

The length of row = 3.2 inches.

Step-by-step explanation:

The length of a chocolate = 4/5 inch

Total number of chocolate pieces placed = 4

Now we have given the length of one chocolate and it is required to find the total length of the row when four chocolates are placed end to end. So in order to find the length of the chocolate row we have to multiply the size of one chocolate by the number of chocolates.

The length of row = Length of one chocolate × number of chocolates

The length of row = 4/5 × 4

The length of row = 3.2 inches.

The piece of chocolate and the number of chocolates in a row can be represented using equations.

A row of chocolate is 3.2 inches long

Given that:

[tex]L = \frac 45[/tex]  ---- Length of a piece

[tex]n =4[/tex] --- number of chocolate pieces

The length of the chocolate in a row is calculated as follows:

[tex]Length = n \times L[/tex]

So, we have:

[tex]Length = 4 \times \frac 45[/tex]

[tex]Length = 4 \times 0.8[/tex]

[tex]Length = 3.2[/tex]

Hence, a row of chocolate is 3.2 inches long
