Answer:

10 cm²

Step-by-step explanation:

74 088 is the cubed of one side. So you would do [tex]\sqrt[3]{74088}[/tex] which is 42. So one side of the cube is 42. To find the surface area, you would do 6(42x42) which would give you 10584. Remember to put cm²

Answer: D

Step-by-step explanation: In this problem, we want find the difference between each of the x-term and each of the y-terms.

Let's begin with the x-terms.

Notice that the difference between 1 and 0 is +1, the difference between 2 and 1 is +1, the difference between 3 and 2 is +1, and the difference between 4 and 3 is +1.

Now, looking at the y-terms.

The difference between 5 and 2 is +3, the difference between 8 and 5 is +3, the difference between 11 and 8 is +3, and the difference between 14 and 11 is +3.

To write an equation, we need to know the multiplier and the base.

The multiplier will be equal to the change in y over the change in x.

The change in y is always +3 and the change in x is always +1.

So we have [tex]\frac{+3}{+1}[/tex] which is equal to +3.

This means that the multiplier is equal to 3.

Next, we want to find the base or the value of y when x is equal to 0. The base is equal to  when x is equal to 0.

Now to write an equation from the data in the table, we begin with the equation y = mx + b where m is the multiplier and b is the base.

We know that the multiplier is 3 and the base is 2.

So we have y = 3x + 2.

So your answer is D.

Step-by-step explanation:

PEMDAS

Parentheses

Exponents

Multiplication

Division

Addition

Subtraction

-Since there are parentheses you do that first, so multiplication.

Final answer:

The first operation to perform when simplifying the expression is D: Multiplication, specifically within the brackets where it states 54 × 6. The answer is option D.

Explanation:

When simplifying the expression 63 − (2 + 54 × 6) ÷ 5, according to the order of operations, commonly known as PEMDAS or BEDMAS, we must first perform the operation in the Brackets (in American English, Parentheses are used instead of Brackets).

Within the brackets, the correct sequence of operations is Exponentiation, Multiplication/Division (from left to right), and then Addition/Subtraction (from left to right). Since there is no exponentiation in the brackets, we start with multiplication (54 × 6), which will affect the result within the brackets before performing the addition (2 + ...) and then division ÷ 5. Therefore, the first operation to perform is D: Multiplication.

Set up a system of equations:

B=2+3C

B+C=90

The variable B is already solved, so plug into bottom equation:

2+3C+C=90

2+4C=90

4C=88

C=22

Plug C back in:

B+22=90

B=68

So B is 68 degrees and C is 22 degrees

The problem involves an algebraic expression where Ben, Tracy, and Tran each spend an equal amount, n, on skate rentals that total $15. By setting up an equation, we solve for n, which is $5 per person. This concept is related to understanding budget constraints in financial decision-making.

The student's question about Ben, Tracy, and Tran spending a total of $15 to go skating where they each rented skates for n dollars pertains to algebraic expressions and equations, which is a mathematics concept commonly explored in college-level courses. If we assume that each of them paid an equal amount for the skate rental, represented by n, then we can express the total cost as 3n because there are three individuals.

Given that the total cost was $15, we can set up an equation: 3n = $15. To find the cost of renting skates per person, we solve for n by dividing both sides of the equation by 3, resulting in n = $5. Therefore, each person paid $5 to rent the skates.

Understanding how to solve this problem helps in grasping the concept of budget constraints, as seen in the example of Janet Bain who must decide how to allocate a limited budget of $250 for activities such as skiing and horseback riding. This topic relates to the decision-making processes regarding spending within the constraints of a budget, which is essential in both personal and organizational finance.

Answer:

Explanation:

The student used convenience sampling.

The population of the study is the entire population of students of the school.

Since it is time consuming to survey all the students, the high school volunteer student needs to survey a sample.

A systematic random sample would have used a procedure, algorithm,  method (a system) to select a random sample. This is not what the student did, thus the first option is incorrect.

A voluntary sampling consits of volunteer people who agree to take part in the study and answer the survey. This isn't either how the sample was choosen, thus the second option is also incorrect.

A convenience sample is when the sample is chosen for the researcher's ease, i.e. convenience. In this case, the student decided to survey only members of his class instead of selecting a representative sample of all the classes. This sample is not random, since not every member of the population has equal chances to be chosen, but it is easy for the student to survey a group that is very close to him. Hence, the third statement is correct.

The was not an statrified sampling (fourth choice), since statrified sampling consists in creating different groups and chosing some members from every group. This is not what the researcher did.

Answer:

p= 23

Step-by-step explanation:

Julie has 27 necklaces and 54 earrings.

Let's assume Julie has x necklaces. Since she has twice as many earrings as necklaces, she would have 2x earrings.

We know that Julie has a total of 81 pieces of jewelry, which includes both necklaces and earrings. Therefore, we can set up a system of equations to represent the given situation:

Equation 1: x + 2x = 81

In Equation 1, we add the number of necklaces (x) and the number of earrings (2x) together, resulting in 81, which is the total number of pieces of jewelry Julie has.

Now, we can solve Equation 1 to find the value of x:

3x = 81

x = 81 / 3

x = 27

So, Julie has 27 necklaces.

To find the number of earrings she has, we can substitute the value of x back into the equation:

2x = 2 * 27

2x = 54

Thus, Julie has 54 earrings.

julie has 81 pieces of jewelry. she has twice as many earrings as she has necklaces How many of each does julie have? Write a system of equations for the situation. (two seperate equations ). find the solution.

Final answer:

Using basic algebra, Julie has 27 necklaces and 54 earrings. We found this by setting up the equation 2N + N = 81, solving for N (number of necklaces), and then multiplying by 2 to get the number of earrings.

Explanation:

The student's question regarding Julie's 81 pieces of jewelry can be solved using basic algebra. We know that the number of earrings is twice the number of necklaces. Let's define the following:

We're given that T = 81, so we can substitute E with 2N to get the equation:

Hence, Julie has 27 necklaces. Now we can find the number of earrings:

Therefore, Julie has 54 earrings and 27 necklaces.

To find the two numbers, set up a system of equations and use the method of elimination to solve. The two numbers are 5/2 and 13/8.

Explanation:

To find the two numbers, we can set up a system of equations. Let's say the two numbers are x and y. We have the following information:

x + y = 4 1/8

x - y = 7/8

To solve this system, we can use the method of elimination. We can add the two equations together to eliminate the variable y:

(x + y) + (x - y) = 4 1/8 + 7/8

2x = 5

x = 5/2

Substituting this value back into one of the original equations, we can solve for y:

(5/2) + y = 33/8

y = 33/8 - 5/2

y = 33/8 - 20/8

y = 13/8

Therefore, the two numbers are 5/2 and 13/8.

Answer:0.5

Step-by-step explanation:

Answer:It  equals -7/20 because Here's how to convert 0.35 to a fraction... There is not much that can be done to figure out how to write 0.35 as a fraction, except to literally use what the decimal portion of your number, the .35, means. Since there are 2 digits in 35, the very last digit is the "100th" decimal place. So we can just say that .35 is the same as -35/100. The fraction -35/100 is not reduced to lowest terms. We can reduce this fraction to lowest terms by dividing both the numerator and denominator by 5. Why divide by 5? 5 is the Greatest Common Divisor (GCD) or Greatest Common Factor (GCF) of the numbers 35 and 100.

So, this fraction reduced to lowest terms is -7/20.

So your final answer is: 0.35 can be written as the fraction -7/20

Answer:

-1/4(8x+12y)=-2x-3y

The expanded equivalent expression of -1/4(8x+12y) is -2x - 3y.

The given mathematical expression is: -1/4(8x+12y). To expand and simplify this expression, we need to apply the distributive property of multiplication over addition, which means we multiply -1/4 with both 8x and 12y separately. So, the first step would be -1/4 * 8x which becomes -2x. Doing the same for the second term, -1/4 * 12y, the result will be -3y. Therefore, the equivalent expanded expression becomes

-2x - 3y

Answer: [tex]d = 20m[/tex]

Step-by-step explanation:

The formula for calculating the area of square is given by :

Area = [tex]s^{2}[/tex]

where s is the length of a side , that is

200 =  [tex]s^{2}[/tex]

Therefore :

[tex]s = \sqrt{200}[/tex]

[tex]s = 10\sqrt{2}[/tex]

Recall that the diagonals of a square meet  at right angle , then we can calculate the diagonal by Pythagoras theorem , that is

[tex]d^{2}[/tex] = [tex](\sqrt{10})^{2}[/tex] +  [tex](\sqrt{10})^{2}[/tex]

[tex]d^{2} = 200 + 200[/tex]

[tex]d^{2} = 400[/tex]

[tex]d = \sqrt{400}[/tex]

[tex]d = 20m[/tex]

Answer:

Speed of shuttle in km per hr =        30069.86 km per hr

Speed of shuttle in miles per hr       =    18643.31  miles per hr

Step-by-step explanation:

Speed of space shuttle in feet per second= 27,404 feet per second

As

One foot per second = 1.09728 kilometers per hour,

The speed in kilometers per hour is equal to the feet per second multiplied by 1.09728

So

To find  out speed of shuttle in km per hour we will mutilpy our speed with 1.09728

              27404 ft per sec         =         27404x 1.09728 km per hr

    speed of shuttle in km per hr =        30069.86 km per hr

Now

As we know 1km = 0.621371 miles

To convert this speed into miles per hr we will multiply our speed with 0.621371

        30069.86 km per hr   =    30069.86x0.621371 miles per hr

     speed of shuttle in miles per hr       =    18643.31  miles per hr
