$72 earned on monday

Step-by-step explanation:

Delta pays Pete Rose $360 per day in the maintenance department at air port. Pete became I'll Monday and went home after 1/5 of a day

Delta works for only 1/5 of the day

To get the amount earn , multiply the work done by the rate

[tex]\frac{1}{5} \cdot 360 =72[/tex]

So $72 earned on monday

Pete Rose earns $360 per full day of work. On Monday, he worked for 1/5 of the day before becoming ill. By calculating 1/5 of his daily rate, we find that Pete earned $72 for that day.

The student's question is about calculating Pete's earnings for the part of the day he worked before he became ill. Since Pete earns $360 for a full day, we want to find out what he earns for 1/5 of that day, as 1/5 of the day is the amount of time he worked before going home.

Therefore, on Monday, Pete earned $72.

Answer:

it is B 2.5

Step-by-step explanation:

The height of the pan that he should use for the batter to completely fill the pan is 2.5 inches.

From this interactive, formula for volume is V = l w h (volume equals length times width times height) and can also be written V = B h (volume equals the area of the base times the height).

The volume is equal to the product of the area and height of the shape. Volume = Base Area x Height.

Given:

Base Area= 45 sq. inches

Volume= 112.5 cubic inches

So,

Volume= Base Area x Height

112.5 = 45 x Height

Height= 112.5 / 45

Height =  2.5 inches

Hence, the height of the pan that he should use for the batter to completely fill the pan is 2.5 inches.

Answer:

r > -178

Step-by-step explanation:

Solving the equations means to find what "r" can be for the equation to be true.

If the sign < confuses you, you can always write = then change it back.

To find "r", we need to isolate it. To do this, we move "r" to the left side, and every other number to the right side. When you move something to the other side, remember you need to do the reverse operation on both sides.

I want to move -195 first. The opposite is +195.

-17 < -195 - r

-17 + 195< -195 + 195- r    Add 195 to both sides. 195 cancels out on the right

-17 + 195 < -r           Simplify left right by add 195 to -17

178 < -r             The opposite of multiply by -1 is divide by -1.

178/-1 < -r/-1          Divide both sides by -1.

178/-1 < r          "r" is isolated now. Simplify left side

-178 < r          Answer is found. Put variable on left side. Remember the keep the open side of the symbol facing "r".

r > -178         The solution is when "r" is greater than -178.

Answer:

253.75

Step-by-step explanation:

Answer:

17576 Combinations.

Step-by-step explanation:

There are 26 letters in the Current English Lexicon (Alphabet), If there are 3 letters in a person's initials, then our equation would turn out to be "26³ =  17576". So, There are 17576 different possible combinations.

Final answer:

The total number of possible initials a person can have, using the first letters of their first name, middle name, and last name in the English alphabet, is 17,576. This is calculated by multiplying the number of alphabet letters (26) for each initial, resulting in a product of 26 x 26 x 26.

Explanation:

To calculate the number of possible initials a person can have from their first name, middle name, and last name, we must consider that each initial can be any letter from the English alphabet, which has 26 letters. Since each initial is independent of the others, the total number of possible initials is found by multiplying the number of options for each initial together.

The calculation is as follows:

First name initial: 26 possibilities (A-Z)

Middle name initial: 26 possibilities (A-Z)

Last name initial: 26 possibilities (A-Z)

So, the total number of possible initials would be:

26 (for the first name) x 26 (for the middle name) x 26 (for the last name) = 17,576 possible initials.

Answer:

Step-by-step explanation:

Answer:

[6 , +∞[

Step-by-step explanation:

Domain of g is all x≥4

domain of f is all real numbers

domain of goh is all real numbers x that verify 2x-8≥4 ⇒ x≥6

The restriction on the domain of goh is x ≥ 4.

To find the restrictions on the domain of goh, we need to consider the compositions of the two functions g(x) and h(x).

It is important to note that the square root function √x has a restriction on its domain. The expression inside the square root must be greater than or equal to zero. So, for g(x), we have x - 4 ≥ 0. Solving for x, we find that x ≥ 4.

Now, let's consider the composition goh(x). We substitute h(x) into g(x) as follows: goh(x) = g(h(x)) = g(2x-8).

The domain of h(x) is all real numbers, so we don't have any restriction for h(x). However, when we substitute h(x) into g(x), we must make sure that the resulting expression is within the domain of g(x), which is x ≥ 4. Therefore, the restriction on the domain of goh is x ≥ 4.

Answer: The five exponent properties are

Product of Powers: When you are multiplying like terms with exponents, use the product of powers rule as a shortcut to finding the answer. It states that when you are multiplying two terms that have the same base, just add their exponents to find your answer.

Power to a Power.: When raising a power to a power in an exponential expression, you find the new power by multiplying the two powers together. ... Then multiply the two expressions together. You get to see multiplying exponents (raising a power to a power) and adding exponents (multiplying same bases).

Quotient of Powers.:  When you are dividing like terms with exponents, use the Quotient of Powers Rule to simplify the problem. This rule states that when you are dividing terms that have the same base, just subtract their exponents to find your answer. The key is to only subtract those exponents whose bases are the same.

Power of a Product: The Power of a Product rule is another way to simplify exponents. ... When you have a number or variable raised to a power, it is called the base, while the superscript number, or the number after the '^' mark, is called the exponent or power.

Power of a Quotient.: The Power of a Quotient rule is another way you can simplify an algebraic expression with exponents. When you have a number or variable raised to a power, the number (or variable) is called the base, while the superscript number is called the exponent or power

You can use these any way you want to rewrite an equation.

The properties of exponents are rules to simplify expressions with powers, which include adding exponents when multiplying like bases, multiplying exponents when raising powers to powers, and subtracting exponents when dividing like bases.

The properties of exponents are mathematical rules used to rewrite expressions involving powers in simpler or alternative forms. These properties are essential for performing operations with exponents and include rules for multiplying, dividing, and raising powers to powers.

Examples of Exponent Properties

Multiplying Powers with the Same Base: 10³ × 10² = 10³+2 = 10µ.

Raising a Power to a Power: (5³)⁴ = 5³×4 = 5¹², or 5 multiplied by itself 12 times.

Negative Exponents: 2.4 x 10⁻² tells you to move the decimal point to the left twice, which equals 0.024.

Application of Exponent Properties

To apply these properties, you would systematically use the appropriate rule based on the operation you're performing. For multiplication, add the exponents when the bases are the same. For powers, multiply the exponents. For division, subtract the exponents when the bases are the same. Using these rules simplifies complex expressions and makes it easier to work with exponents in algebra and science.

Answer:

Step-by-step explanation:

The volume formula for a cylinder is B*h

B : the area of the base

h : the height

Cylinder 1

The volume is 8pi

Cylinder 2

The volume is 32pi

Cylinder 3

The volume is 72pi

Answer:

Cylinder 1:  V = 8π

Cylinder 2:  V = 32π

Cylinder 3:  V = 72π

Step-by-step explanation:

The volume of the cylinder of radius r and height h is calculated using the form:  V = π r² h

Cylinder 1:  r = 1 cm  and  h = 8 cm

Volume of Cylinder 1 = π r² h = π 1² * 8 = 8π

Cylinder 2:  r = 2 cm  and  h = 8 cm

Volume of Cylinder 2 = π r² h = π 2² * 8 =  π * 4 * 8 = 32π

Cylinder 3:  r = 3 cm  and  h = 8 cm

Volume of Cylinder 1 = π r² h = π 3² * 8 = π * 9 * 8 = 72π

Option C

Math teacher would need to buy 130 prizes

Solution:

Given that,

Math teacher currently has 109 students and the box has 88 prizes in it

The math teacher likes to keep at least twice as many prizes in the box as she has students

So, she wants the number of prizes to be twice the number of students

Therefore,

number of prizes = 2 x 109 students

number of prizes = 2 x 109 = 218 prizes

The box has 88 prizes in it

Therefore, number of prizes she would need to buy is:

⇒ 218 - 88 = 130

Thus she would need to buy 130 prizes

Answer:

y>- 22/63

Step-by-step explanation

-65y+19<-2y+41

-65y+2y<41-19

-63y<22

y>-22/63

The solution to the inequality is y > -22/63.

To solve the inequality -65y + 19 < -2y + 41 for y, we'll follow these steps:

-65y + 19 < -2y + 41

First, we'll combine like terms by moving the terms with y to the left side and the constant terms to the right side:

-65y + 2y < 41 - 19

-63y < 22

Next, we'll isolate y by dividing both sides of the inequality by -63. Remember that when we divide by a negative number, the inequality sign flips:

y > 22 / -63

Simplifying the fraction:

y > -22/63

Therefore, the solution to the inequality is y > -22/63.

Answer:

y = 2.50 , x = 1.25

Step-by-step explanation:

x = soft tacos

y = double deckers

Dory:

3x + 3y = 11.25 

Nemo:

4x + 2y = 10.00

---Now to solve for x and y---

---We find LCM of either x or y then make them cancel each other---

Dory multiply by 2:

6x + 6y = 22.50

Nemo multiply by 3:

12x + 6y = 30.00

--eliminate y--- 

Nemo subtract Dory:

6x = 7.50

Therefore x = 7.50 ÷ 6 = 1.25

---Now substitute x = 1.25 in either equation.---

Dory:

3.75 + 3y = 11.25

Therefore 3y = 11.25 - 3.75

therefore 3y = 7.50

there fore y = 2.50

y = 2.50 , x = 1.25

Answer:

x= $2.50, y= $1.25

Step-by-step explanation:

X= soft taco

Y= double deckers

$11.25= 3x+3y

$10.00= 4x+2y

first eliminate 1 variable, lets say d, to do this we must cancel them out, to do this multiply the top by -2 and the bottom by 3

 -2 ($11.25= 3x+3y)                                      -$22.50= -6x-6y

 3 ($10.00= 4x+2y)     which becomes.          $30.00=12x+6y

then the -6y and the positive 6y cancel out and you are left with 1 variable  

after this add the remaining parts to get.

$7.50=6x  divide by 6, then put x back into one of your original equations and solve for d then you have found how much each item costs and are finished with the system of equations
