Answer:

D. Bank charges a large fee for bouncing a check is not an example of overdraft protection.

Step-by-step explanation:

Overdraft protection is a service offered by banks that allows you to link your checking account to another account, such as a savings account or a line of credit. If you overdraw your checking account, the bank will automatically transfer funds from the linked account to cover the shortfall, which helps you avoid overdraft fees and other penalties.

Option A is not an example of overdraft protection as it refers to earning interest on money in your savings account, which is a separate service.

Option B refers to additional fees collected by the bank when you bounce a check, which is a penalty for not having sufficient funds in your account to cover the check.

Option C refers to an ATM machine providing you with cash, which is a basic function of an ATM and is not related to overdraft protection.

It is a mixed number:

THe whole part, 5, is going to stay 5.

Now, let's work with the fractional part.

7/10 into a decimal would require for division.

7 divided by 10 is 0.7

Thus,

IN Decimal, it will be "5.7"

To find percentage from decimal, we multiply by 100 and tag along a % sign.

So,

The number, in percentage, is 570%

The simplified form of -20/2(7 2/3) is -230/3.

To solve the expression -20/2(7 2/3), we need to follow the order of operations, which states that we should perform the operations inside parentheses first, then any multiplication or division from left to right, and finally any addition or subtraction from left to right.

First, let's convert the mixed number 7 2/3 to an improper fraction.

7 2/3 = (7 * 3 + 2) / 3 = 23/3

Now, let's substitute the value back into the expression:

-20/2 * (23/3)

Next, we simplify the multiplication:

-10 * (23/3)

To multiply a fraction by a whole number, we multiply the numerator by the whole number:

-10 * 23 / 3

Now, we perform the multiplication:

-230 / 3

Therefore, the simplified form of -20/2(7 2/3) is -230/3.

Answer:

50 km

Step-by-step explanation:

Given

\(r = 4cm : 20km\) -- Scale ratio

Required

Actual representation of 10cm

Let the actual measurement be x.

So, we have:

\(r =10cm:x\)

Equate both value s of r

\(10cm : x = 4cm : 20km\)

Express as fraction

\(\frac{x}{10cm } =\frac{20km}{4cm}\)

Multiply by 10cm

\(10cm * \frac{x}{10cm } =\frac{20km}{4cm} *10cm\)

\(x =\frac{20km}{4} *10\)

\(x =5km *10\)

\(x =50\ km\)

Answer:

P = 6 + 4w

Step-by-step explanation:

The length of a rectangle is 3 times greater than its width

Therefore the perimeter of a rectangle can be calculated as follows

P= 2L + 2w

P = 2(w + 3) + 2w

P= 2w + 6 + 2w

P= 6 + 4w

Hence the expression which gives the perimeter of the rectangle in terms of its width is P = 6 + 4w

Given that the relationship is represented by the equation:

y = x + 5.5

For x = 2

y = 2 + 5.5 = 7.5

For x = 4

y = 4 + 5.5 = 9.5

For x = 5

y = 5 + 5.5 = 10.5

For x = 9

y = 9 + 5.5 = 14.5

The distance equation is Speed=d/h

Speed of an object is given by distance dived by the time taken.

Given here, d=2¹/₃

                     = 7/3 miles

                   h= (7/2)×1/60 hours

The total surface area of the prism is determined as  216 cm².

The surface area of the prism is calculated by applying the following formula.

The area of the two triangular faces is calculated as follows;

Area of the two triangles = 2 (¹/₂ x base x height )

Area of the two triangles = 2 (¹/₂ x 6 cm x 4 cm )

Area of the two triangles = 24 cm²

The area of rectangular faces is calculated as follows;

A = ( 5 cm x 12 cm ) + (5 cm x 12 cm ) + ( 6 cm x 12 cm )

A = 192 cm²

The total surface area of the prism is calculated as follows;

Area = 24 cm² + 192 cm²

Area = 216 cm²

Option D

Step-by-step explanation:

Volume of a cylinder is \(V=\pi r^2h\)

h - height

r - radius

We are given the radius of 2.1 centimeters and the height of 5 centimeters.  

Using 3.14 for pi:

\(V=3.14*2.1^2*5\\\\V =69.237\)

69.237 ≈ 69.2

Option D should be the correct answer.

The formula for the 'B' variable is V/MK

To solve for the variable B is to make it the subject of formula.

Subject of formula is the variable that is expressed in terms of the other variables in a given formula, expression, function or equation.

Example;

In the equation,  2x + y = 4, let's make 'y' the subject of formula

y = 4 - 2x

Given the expression;

V=BMK

To make 'B' the subject, we need to divide both sides by the coefficients of B, we have;

7w^2-18w/w^2-5w+6

The simplest form of the expression is 7w/w^2+6, the correct option is A.

Expression in mathematics is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

We are given that;

4w/w-2 + 3w/w-3

Now,

we can multiply the numerator and denominator by the missing factor. For example

w−24w​=(w−2)(w−3)4w(w−3)​

w−33w​=(w−2)(w−3)3w(w−2)​

Add the fractions with the LCD as the common denominator. To do this, we can add the numerators and keep the denominator. For example:

w−24w​+w−33w​=(w−2)(w−3)4w(w−3)+3w(w−2)​

Simplify the numerator by distributing and combining like terms. For example:

(w−2)(w−3)4w(w−3)+3w(w−2)​=(w−2)(w−3)4w2−12w+3w2−6w​

(w−2)(w−3)4w2−12w+3w2−6w​=(w−2)(w−3)7w2−18w​

=7w/w^2+6

Therefore, by the given expression the answer will be 7w/w^2+6.

Answer:

Find the slope and the y-intercept

Step-by-step explanation:

To find slope, use the equation \(\frac{y-y}{x-x}\). First, find two points on the line that are near each other and are whole numbers. Then you substitute the points into the equation.  So for example, if I had the points (0,0) and (1,2), the substitution would be:

\(\frac{2-0}{1-0}\)

To find the y-intercept, find where the line crosses over the y-axis. Then put in the y value.

If you do not know where to put slope and y-intercept:

y=mx+b

m=slope

b=y-intercept

slope= output/input

Answer:

the answer may vary, seeing as you could use any of the coordinates, but in my case i got : y = -1/2 + 4

Step-by-step explanation:

formula : y = mx + b

to find your ' b ' you had to determine where the y intersects. in this case, it intersected on positive four.

The percent decrease in total principal and interest paid between a 30-year term mortgage and a 15-year mortgage with a principal balance of $484,500.00 and a 6.5% APR is 31.0%. (Option A)

To calculate the  percent decrease, we can use the following formula.

Percent decrease = ( (30-year factor -   15-year factor) / 30-year factor) x 100

Substituting the values from the chart.  

= (($ 6.65 - $8.71) / $6.65) x 100

= ( -$ 2.06 / $6.65) * 100

= -0.309 *  100

Percent decrease ≈ - 30.9 %

Since the question asks for the percent decrease as a positive value, we take the absolute value of the result which is
