Martin spent $300 from his savings account on a new bike. He also deposited $300 in his savings account that he earned from selling his used textbooks. Which integer represents the change in Martin's savings? A) $100 B $0
C. -100$ D. -$200​

Answers

Answer 1

Answer:

B

Step-by-step explanation:

a money account works in the same way as real things we can touch.

so, when I have 300 apples at a place (e.g. a grocery store), then I take away 300 apples, and then put again 300 apples there - how many apples will be there at that moment ?

we had 300 and took away 300.

300 - 300 = 0

at that moment we have 0 apples.

but then we put again 300 apples there.

0 + 300 = 300

so, we end up with 300 apples. the same number we started with.

and the same way for the savings account.

he takes out $300.

that means he has now $300 less on his account.

and then he adds $300.

so, he added exactly the same amount as he took out earlier, which means nothing else than that he undid his earlier action regarding his bank account.

so, his balance is now exactly the same as before he did the first transaction.

therefore the change is exactly : $0

Answers

Answer:

139

Step-by-step explanation:

If x=-5

then

5*-5^2-(-5)+9

5*25+5+9

139

Answer: 139

Concept:

Here, we need to understand the idea of evaluation.  

When encountering questions that gave you an expression with variables, then stated: "If x = a, y = b, z = c" (a, b, c are all constants), this means you should substitute the value given for each variable back to the expression.

Solve:

Given information

5x² - x + 9

x = -5

Substitute value into the expression

=5(-5)² - (-5) + 9

Simplify exponents

=5 (25) + 5 + 9

Simplify by multiplication

=125 + 5 +9

Simplify by addition

Answer:

pi*z^2*a or "pizza"

Step-by-step explanation:

The dimensions given describe a cylinder, for which the basic volume formula would be base x height.

The base would be a circle, with the radius z as given while the height is a.

The formula for the area of a circle is pi * r^2, and our radius is z, so the area of a circle with radius z is pi * z^2.

Now, all we need to do is multiply by the height, a. This gives us a volume of pi* z^2 *a

Side note:

z^2 can be written as zz, so the actual area of the pizza could be represented by "pizza".

Answer:

x = 70

Step-by-step explanation:

To find the value of x we need to

we know that the figure is an isosceles triangle so the base angles will be equal

we also know that angle sum of triangle is 180

so

40 + x + x = 180

40 + 2x = 180

2x = 180 - 40

2x = 140

x = 140/2

x = 70

What are the two conditionals that form the statement below? Two numbers are reciprocals if and only if the product is one

The two conditional are:

2. Two numbers are reciprocals only if their product is one.

But that #2 is another way to say
2. If two numbers are reciprocals, then their product is one.

This is how “if and only if” statements work, that knowing one side of the statement is true guarantees you know the other side is too and it has to work both ways.

Sami orders cowboy hats online for a party. They cost $11.95 each with a shipping fee of $7.95.
Sami recently paid $223.05 for some cowboy hats.
Write an equation that to find the number of cowboy hats Sami ordered. Then find the number of
cowboy hats she ordered,

Answers

Answer:

223.05/x(11.95+7.95) 11.21.

Step-by-step explanation:

If each hat costs 11.95 plus a shipping fee of 7.95, you must add those numbers together. This makes the variable that will help indicate the number of hats ordered. Then you divide 223.05 by 19.9 (the total cost per hat) and you'll get your answer of 11.21 rounded.

C using Pythagorean theorem
Answer:

√97 units

Step-by-step explanation:

AB represents the largest side of the triangle so in order to solve for that side, use Pythagorean Theorem.

Pythagorean Theorem: a^2 + b^2 = c^2
where a = height b = base and c = the largest side

Step 1. Find the length of AC (represented as a)

Answer: 9 units

Explanation: either count how many units or use the distance formula

Step 2. Find the length of CB (represented as b)

Answer: 4 units

Explanation: either count how many units or use the distance formula

Step 3. Substitute a for 9 and b for 4 units in Pythagorean Theorem

9^2 + 4^2 = c^2

Step 4. Simplify the exponents

81 + 16 = c^2

Step 5. Solve for c^2

c^2 = 81 + 16

c^2 = 97

Step 6. Square root c^2

c = √97

Answers

Answer:

X=64°

Step-by-step explanation:

Solution,

x+54°=118° because the sum of two interior angles is equal to the opposite non adjacent exterior angle.

x+54°-54°=118°-54°

x=64°

Answer:

64 degrees

The Process:

54 is already a number that's not going to change, so that's fine. 118 is an outside angle, and a flat line is 180 degrees, so to find the inside angle, you have to do 180 - 118. Once again, there are 180 degrees in a triangle to you need to add 180 - ((180 - 118) +54) and you have the value of x.

A goat is grazing outside of a rectangular barn that has dimensions 20 ft by 30 ft.
He's tied to a corner of the barn with a 12 ft rope. Find the grazing area of the goat.

Answers

Answer:

108π  ft² or  339.29 ft²

Step-by-step explanation:

Refer to attached picture.

The grazing area of the goat is 3/4 of area of circle with 12 ft radius:

A = 3/4(πr²) = 3/4(π*12²) = 108π  or  339.29 ft²

Tied to the corner

Means 1part among 4parts of circle or a quarter area
