Someone please help. Explain why it might be easier to solve the multiplication problem by changing it from this: 5×98×2 , to this: 5×2×98 . Use a property of multiplication to justify your reasoning.

Answers

Answer 1

Answer:

Because it is easy to multiply 5 by 2 which is 10......and then 10 × 98 youbjust have to add 0 to 98.....which will be 980

Answer 2

The multiplication problem can be simplified by the equation A = 5 x 2 x 98 and the value of A = 980

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

Substituting the values in the equation , we get

A = 5 x 98 x 2

On simplifying , we get

From the associative property , we get

A = ( 5 x 2 ) x 98

where the value of 5 x 2 = 10

So , the multiplication expression is

A = 10 x 98

A = 980

Therefore , the value of A is 980

Hence , the equation is A = 980

A. The slope is 10
B. The slope is 1/10.
C. The slope tells me that the hourly rate for babysitting is $10.
D. The slope tells me that the hourly rate for babysitting is $20.

Answers

Answer:

A and c

Step-by-step explanation: i did some research.

The slope of a function is the rate of change of the function.

The true statements are:

A. The slope is 10 C. The slope tells me that the hourly rate for babysitting is $10.

From the graph, we have the following points

[tex]\mathbf{(x_1,y_1) = (0,10)}[/tex]

[tex]\mathbf{(x_2,y_2) = (1,20)}[/tex]

The slope (m) is calculated as follows:

[tex]\mathbf{m = \frac{y_2 - y_1}{x_2 - x_1}}[/tex]

So, we have:

[tex]\mathbf{m = \frac{20-10}{1-0}}[/tex]

[tex]\mathbf{m = \frac{10}{1}}[/tex]

[tex]\mathbf{m = 10}[/tex]

The slope is the rate of change of the y values over the x values.

Hence, the true statements are:

A. The slope is 10 C. The slope tells me that the hourly rate for babysitting is $10.

Alonzo will rent a car for the weekend. He can choose one of two plans. The first plan has an initial fee of $50 and costs an additional 0.10 per mile driven. The second plan has no initial fee but costs 0.60 per mile driven. How many miles would Alonzo need to drive for the two plans to cost the same?

Answers

Answer:

100 miles

Step-by-step explanation:

If Alonzo drives 0 miles, then the first plan would cost him 50 dollars and the second plan would cost him nothing.

If Alonzo drives 10 miles, then the first plan would cost him 51 dollars and the second plan would cost him 6 dollars.

From these statements, we can observe that the second plan is increasing at a rate 6 times the first one and will overtake it at one point.

Our solution is the point of intersection between these two functions - where they cost the same.

To find this, equate

0.1x + 50 = 0.6x

where x is the number of miles Alonzo drives,

multiply the equation with 10 to get,

x + 500 = 6x

subtract x,

5x = 500

and divide 5,

x = 100.

So at 100 miles, both plan 1 and 2 will cost 60$. This is our answer. Good Luck!

polygon QRST has vertices Q41/2 , 2 R 8/2 ,2 S 8 1/2 , -3 1/2 and T 4 1/2,-3 1/2 is polygon qrst a reactangle? justify your anwerer

Answers

Answer:

QRST is a rectangle.

Step-by-step explanation:

To decide whether this is a rectangle or not, we have the following options to choose from:

Prove that:

2 pairs of sides are parallel and one angle is 90°

2 pairs of opposite sides are equal and one angle is 90°

1 pair of sides is parallel and equal and one angle is 90°

All four angles are 90°

The diagonals are equal and bisect each other. (same midpoint)

I will go with option 1, because this only requires finding the slope of each of the 4 lines.

Note that:

points Q and R have the same

y

value

horizontal line

points S and T have the same

y

value

horizontal line

points Q and T have the same

x

value

vertical line

points R and S have the same

x

vertical line

Therefore QRST has to be a rectangle because horizontal and vertical lines meet at 90°.

The opposite sides are therefore parallel and equal and the angles are 90°
