Jose has $178.74 in his checking account. He wrote checks for $36.52, $18.92, and $25.93. He also deposited $300.00, $100.00, and $205.16. What is the final balance in Bob's checking account?V

Answers

Answer:

$702.53

Step-by-step explanation:

Start with Jose's initial balance.

[tex]178.74[/tex]

He wrote checks, so we have to subtract the total amount the checks were worth. Let's first add the three amounts.

[tex]36.52+18.92+25.93[/tex]

Solve.

[tex]81.37[/tex]

Subtract the total amount of the checks from Jose's initial balance.

[tex]178.74-81.37[/tex]

Solve.

[tex]97.37[/tex]

The amount above is now what is in Jose's checking account.

But, he also deposited money, meaning he put money in his checking account. Now, let's add the three amounts he deposited.

[tex]300.00+100.00+205.16[/tex]

Solve.

[tex]605.16[/tex]

The amount above is what Jose adds to his checking out.

Add the total value of the deposited money and his new balance.

[tex]605.16+97.37[/tex]

Solve.

[tex]605.16+97.37=702.53[/tex]

Is there a dilation that maps shape II onto shape I? If so, what is the scale factor and is it an enlargement or a reduction?

Answers

Shape II was dilated by a scale factor of 1/3 to form shape I. This is  a reduction since the scale factor is less than 1.

What is transformation?

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

Shape II was dilated by a scale factor of 1/3 to form shape I. This is  a reduction since the scale factor is less than 1.

Find out more on transformation at: https://brainly.com/question/4289712

#SPJ1

Answer: A dilation will map shape I onto shape II. The bottom left coordinate of shape I is (1, 1) and the bottom left coordinate of shape II is (3, 3). So, to get the corresponding coordinates of shape II, multiply the coordinates of shape I by 3. This is true for every set of coordinates. So, the scale factor is 3. Because the scale factor is 3, which is greater than 1, the dilation is an enlargement.

Make y the subject of the formula x=a-2by²

Answers

Answer:

y = ± [tex]\sqrt{\frac{a-x}{2b} }[/tex]

Step-by-step explanation:

Given

x = a - 2by² ( add 2by² to both sides )

x + 2by² = a ( subtract x from both sides )

2by² = a - x ( divide both sides by 2b )

y² = [tex]\frac{a-x}{2b}[/tex] ( take the square root of both sides )

y = ± [tex]\sqrt{\frac{a-x}{2b} }[/tex]

Answer:

[tex]y = a - x \di2b[/tex]

Step-by-step explanation:

[tex]2b {y }^{2} = a - x[/tex]

[tex]2b {y}^{2} \div 2b = a - x \ \div 2b[/tex]

[tex] {y}^{2} = a - x \div 2b[/tex]

[tex]y = \sqrt{a - x \div 2b} [/tex]
