60 times 0.14 = 8.4

You would give $8.40 as a tip of 14% from a bill of $60

Final answer:

To calculate a 14% tip on a $60 bill, you multiply 0.14 by $60, resulting in a tip of $8.40.

Explanation:

To find out how much a 14% tip is on a $60 bill, we need to convert the percentage into a decimal by dividing by 100.

This gives us 0.14 as the decimal form of 14%.

We then multiply this decimal by the total bill amount to calculate the tip: 0.14 × $60 = $8.40

Therefore, the tip would be $8.40.

I think it is B. If you drew a graph of this and the x axis was time and the y axis is the  enrollment then you would get 3  different x values and  1 y value. That's still a function. I've drawn it below.

in the number line, the end points are DG, and the point in between is O

DG = 88

DO = 5x + 12

OG = 2x

Set the equation. The two parts (DO & OG) are equal to the whole (DG)

2x + 5x + 12 = 88

Simplify. Combine like terms

(2x + 5x) + 12 = 88

7x + 12 = 88

Isolate the x. Remember to do the opposite of PEMDAS. Subtract 12 from both sides

7x + 12 (-12) = 88 (-12)

7x = 76

Isolate the x. Divide 7 from both sides:

7x/7 = 76/7

x = 76/7

----------------------------------------------------------------------------------------------------------------------------

Find DO. Plug in "76/7" for x:

DO = 5x + 12

DO = 5(76/7) + 12

Simplify. Remember to follow PEMDAS. Multiply 76 with 5

DO =  380/7 + 12

Next, divide 380 with 7

DO = 54.29 (rounded)

Finally, add

DO  = 54.29 + 12

DO = 66.29

66.29 is your answer

Answer: He needs to answer 20 emails.

Step-by-step explanation:

Given : Jim has answered 7 e-mails .  (1)

This  is 35% of the e-mails he must answer .

We can write 35% as 0.35.

Let x be the number of emails  he need to answer.

Then, Number of mails he has answered = 0.35x  (2)

From (1) and (2), we have

[tex]0.35=7\\\\\Rightarrow\ x=\dfrac{7}{0.35}=\dfrac{700}{35}=20[/tex]

Hence, he needs to answer 20 emails.

Answer:

No.  He is short by 2 minutes

Step-by-step explanation:

Given that Denzel can mow 1/8 of his yard every 7 minutes.

Hence he can mow the full yard in 7(8) = 56 minutes.

Now he has to do 3/4 of his yard and time is 40 minutes

For 3/4 of yard time taken would be = 3/4 (56) = 42 minutes.

If he had 40 minutes to mow 3/4 of the yard, he will not  have enough time  since he is short of time by 2 minutes.

We have been given an incomplete statement. We are asked to fill in the blank for given statement.

The metric system is based on the number ___.

We know that metric system is an alternative system of measurement used in most countries including the United States. This system includes prefixes like kilo-, hecto-, deka-, deci-, centi-, and milli.

The metric system is based on number 10 as all these units are based on power of 10.

Therefore, option C is the correct choice.

The metric system is based on the number 10.

Here, we have,

The metric system is a decimal-based system of measurement that is widely used around the world. It is designed to be a coherent and consistent system, with units of measurement that are related to each other by powers of 10.

In the metric system, there is a base unit for each quantity being measured, such as meters for length, grams for mass, and liters for volume. The prefixes are then used to indicate multiples or fractions of the base unit. These prefixes are based on powers of 10, which allows for easy conversions between different units within the system.

For example, when we go from a larger unit to a smaller unit within the same measurement category, we move the decimal point to the right by powers of 10. Likewise, when we go from a smaller unit to a larger unit, we move the decimal point to the left by powers of 10.

This decimal-based nature of the metric system makes it highly convenient for scientific and everyday use, as it simplifies calculations and conversions.

The metric system is based on number 10 as all these units are based on power of 10.

Therefore, option C is the correct choice.

The expression would be m - 4 because if Marty ran 4 more miles than Shana, that means that Shana ran 4 less miles than Marty.

The four inequalities are less than, less than or equal to, greater than, and greater than or equal to. Less than means that a number is less than the other number. For example, if you say 4 is less than 7 it is because 4 is less than 7 by 3 which makes 7 value more than 4. For less than or equal to, it means that the number or variable is less than or the same number as the other number. For example, if you say x is less than or equal to 9, that means that x is less than 9 or equal to 9. For greater than, it means that the variable is greater than the other number. For example, if x if greater than 10 than the variable has to be greater than 10 or 11 and so on. For greater than or equal to, it means that the variable is greater than the other number or equal to that number. For example, if x is greater than or equal to 12, then x is greater than 12 or 13 and up or x is equal to 12 or x is 12.

9x^2 − 42xy + 49y^2

Step-by-step explanation:

The product of [tex](3x + 7y)^2[/tex] is: D)[tex]9x^2 + 42xy + 49y^2[/tex]

The product of (3x + 7y)^2 can be found using the formula for squaring a binomial:

(3x + 7y)^2 = (3x + 7y)(3x + 7y)

To calculate this product, you can use the distributive property (FOIL method):

(3x + 7y)(3x + 7y) = (3x * 3x) + (3x * 7y) + (7y * 3x) + (7y * 7y)

Now, simplify each term:

(9x^2) + (21xy) + (21xy) + (49y^2)

Combine like terms:

9x^2 + 42xy + 49y^2

Hey there!!

What is the area of a rectangle?

The area of a rectangle = Length × Breadth

Given :

Length is 6m longer than the width.

Hence, length = 6 + breadth

Area = ( 6 + breadth ) ( breadth )

Area = 6 breadth + breadth²

Area = 775

Hence, 775 = 6 breadth + breadth²

( Let's take the breadth as ' b ' )

775 = 6b + b²

... b² + 6b - 775 = 0

... b² - 25b + 31b - 775 = 0

... b ( b - 25 ) + 31 ( b - 25 ) = 0

... ( b + 31 ) ( b -25 ) = 0

There are two solutions found :

b + 31 = 0 and b - 25 = 0

Hence,

b = -31 and b = 25

As the values can not be in negatives, we take 25

Hence, the value of the breadth is 25.

Length = 6 + b

Length = 31

Hence, the value of the length = 31

Answer:

Step-by-step explanation:

The standard form of an equation of a circle:

[tex](x-h)^2+(y-k)^2=r^2[/tex]

(h, k) - center

r - radius

The formula of a distance between two points:

[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

We have the center (-2, 1) → h = -2 and k = 1.

The radius is the distance between the center and the given point.

Therefore put the coordinates of the points (-2, 1) and (-4, 1) to the formula of a distance between two points:

[tex]r=\sqrt{(-4-(-2))^2+(1-1)^2}=\sqrt{(-2)^2+0^2}=\sqrt{4}=2[/tex]

We have the equation in standard form:

[tex](x-(-2))^2+(y-1)^2=2^2\\\\(x+2)^2+(y-1)^2=4[/tex]

Convert to the genereal form using:

[tex](a\pm b)^2=a^2\pm2ab+b^2[/tex]

[tex](x+2)^2+(y-1)^2=4\\\\x^2+2(x)(2)+2^2+y^2-2(y)(1)+1^2=4\\\\x^2+4x+4+y^2-2y+1=4\\\\x^2+y^2+4x-2y+5=4\qquad\text{subtract 4 from both sides}\\\\\boxed{x^2+y^2+4x-2y+1=0}\to\boxed{B.}[/tex]
