Using the Pythagorean theorem to check for a right angle, Stephanie's table measurements of 15 inches by 7.5 inches with a diagonal of 17 inches do not satisfy the theorem. Hence, the table is not perfectly rectangular.

To determine if Stephanie’s table is perfectly rectangular, we can apply the Pythagorean theorem, which states that in a right-angled triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides. If the table is perfectly rectangular, the diagonal should be the hypotenuse of a right triangle formed by the length and width of the table.

The formula for the Pythagorean theorem is “a2 + b2 = c2”, where c is the hypotenuse, and a and b are the other two sides of the triangle. For Stephanie’s table: Length (“a”) = 15 inches, Width (“b”) = 7.5 inches, and Diagonal length (“c”) = 17 inches.

Let’s calculate it:

a^2 = 15^2 = 225
b^2 = 7.5^2 = 56.25
c^2 = 17^2 = 289

Add a2 and b2 together:

225 + 56.25 = 281.25

Since 281.25 is not equal to 289, the table is not perfectly rectangular because the measurements do not satisfy the Pythagorean theorem.

The table is not perfectly rectangular because the measured diagonal does not satisfy the Pythagorean Theorem with the given length and width.

To determine if Stephanie's table is perfectly rectangular, we can use the Pythagorean Theorem, which states that for a right-angled triangle, the square of the length of the hypotenuse (diagonal) is equal to the sum of the squares of the other two sides.

Let's denote:
Length (L) = 15 inches
Width (W) = 7.5 inches
Diagonal (D) = 17 inches

According to the Pythagorean Theorem:
D2 = L2 + W2

Now, substitute the given values:
172 = 152 + 7.52
289 = 225 + 56.25
289 = 281.25

Since 289 is not equal to 281.25, the table is not perfectly rectangular. Therefore, the measurements indicate that the table does not form a perfect rectangle.

Answer:

The correct option is;

D) 62 in²

Step-by-step explanation:

Here we have from the drawing, the dimensions of the right rectangular prism are;

Height = 2 in.

Width = 5 in

Length = 3 in

Therefore the surface area is found as follows;

Surface area of right rectangular prism = 2 × Height × Width + 2 × Height × Length + 2  × Width × Length

Surface area of right rectangular prism = 2 × 2 × 5 + 2 × 2× 3+ 2  × 5× 3 = 20 + 12 + 30 = 62 in².

Answer:

(-3,1)

y= 1

x= -3

Step-by-step explanation:

4x-9y=-21

-4x-3y=9

solve the equation

4x=-21+9y

-4x-3y=9

substitute the value of 4x onto an equation

-1(-21+9y)-3y=9

multiply -1 to the numbers in parenthesis

-21+-9-3y=9

add -9 to 9 and put the negative on nine as a positive.

-21-3y=18

add -21 to 18 but since 21 is a negative the equation is subtraction.

-3y=-3

divide Both sides by -3

y=1

substitute the value of y into an equation

-4x-3•1=9

multiply 3 to 1

-4x-3=9

put -3 as a positive and add 3 to 9

-4x=12

divide both sides by -4

x= -3

(-3,1)

The solution for x and y in the given equations is x = 27 and y = 11.

Let's consider the second equation, -x + 3y = 6, and rewrite it in the form ax + by = c.

To get the equation in the required form, we'll rearrange the terms:

-x + 3y = 6

Add x to both sides:

3y = x + 6

Now, subtract 6 from both sides:

3y - 6 = x

This equation can be rewritten in the form ax + by = c by swapping sides:

x = 3y - 6

Now, let's substitute this expression for x into the first equation: 4x - 9y = 9.

4x - 9y = 9 becomes 4(3y - 6) - 9y = 9.

Simplify the equation: 12y - 24 - 9y = 9.

Combine like terms: 3y - 24 = 9.

Add 24 to both sides: 3y = 33.

Divide both sides by 3: y = 11.

Substitute y = 11 into x = 3y - 6: x = 3 × 11 - 6.

Calculate: x = 33 - 6 = 27.

Therefore, the solution for x and y in the given equations is x = 27 and y = 11.

Complete Question:

4x-9y=9; -x+3y=6 Rewrite one of the two equations above in the form ax + by = c, where a, b, and c are constants, so that the sum of the new equation and the unchanged equation from the original system results in an equation in one variable.

The total volume of the figure is 44000 mm³. Ryder used the wrong formula for the total volume.

The composite figure is formed by combinning pyramid and a rectangular prism.

volume of rectangular prism = Bh

where

volume of rectangular pyramid = 1 / 3 Bh

Therefore, the total volume is as follows:

total volume = Bh +  1 / 3 Bh

total volume = 40 × 30 × 5 + 1 / 3 (30 × 40) × 95

total volume = 6000 + 1 / 3 (114000)

total volume = 6000 + 38000

total volume = 44000 mm³

Step-by-step explanation:

Edith needs 10 meters of ribbon to make all 50 school spirit ribbons. To convert from centimeters to meters, we divide by 100. Therefore, 1,000 centimeters is equal to 10 meters.

To answer how many meters of ribbon Edith needs, we first need to understand the relationship between centimeters and meters. In one meter, there are 100 centimeters. Thus, to convert centimeters to meters, we can divide by 100.

Edith needs a total of 1,000 cm of ribbon. In order to convert this to meters, we would do the following calculation: 1000 cm ÷ 100 = 10 meters.

So, the correct answer is D. 10 m. Edith needs to buy 10 meters of ribbon from the fabric store. This is necessary to have enough ribbon to make all 50 school spirit ribbons that are each 20 cm long.

Answer:

16 times

Step-by-step explanation:

Given:

Edgardo has a drink cooler that holds 4 gallons of water.

He is filling the cooler with a 1−quart container.

Question asked:

How many times will he have to fill the quart container to fill the cooler?

Solution:

Capacity of container = 1 quart

As we know:

1 quart = 0.25 gallon

Edgardo has to fill drink cooler having capacity of 4 gallons.

0.25 gallon is filled by filling the container = 1 time

1 gallon is filled by filling the container = [tex]\frac{1}{0.25}[/tex] times

4 gallons is filled by filling the container = [tex]\frac{1}{0.25}\times4=16\ times[/tex]

Thus, he will have to fill the quart container 16 times to fill the cooler.

The question is:

A local in Santa Bárbara was painted by 4 enterprising people who got together to start a dairy business; Juan, Pedro, Carlos and Mario; Juan painted 2/7 of the premises, Pedro painted 5/14 and Carlos painted 2/14; What fraction did Mario paint?

Solution:

Consider the proportion of the total premises painted is 1.

The four enterprising people who got together to start a dairy business are:

Juan (J), Pedro (P), Carlos (C) and Mario (M).

The proportion of premises painted by Juan is:

[tex]P(J)=\frac{2}{7}[/tex]

The proportion of premises painted by Pedro is:

[tex]P(P)=\frac{5}{14}[/tex]

The proportion of premises painted by Carlos is:

[tex]P(C)=\frac{2}{14}[/tex]

Compute the proportion of premises painted by Mario as follows:

P (M) = 1 - P (J) - P (P) - P (C)

        [tex]=1-\frac{2}{7}-\frac{5}{14}-\frac{2}{14}\\=\frac{14-4-5-2}{14}\\=\frac{3}{14}[/tex]

Thus, the proportion of premises painted by Mario is [tex]\frac{3}{14}[/tex].

Answer:

x = 1 and y = -8x

Step-by-step explanation:

Answer:

{y,x} = {-8,1}

Step-by-step explanation:

Solve by Substitution :

// Solve equation [2] for the variable  y

 [2]    y = -8x

// Plug this in for variable  y  in equation [1]

i did it the dumb way and just did 3+5+7+9+11+13+15+17+19+21+23+25 = 168

Answer:

3500-750=2750

2750/300=9.1677

he gets 750 per month .. this means he is sure to get $750 every month.. so he already have $750 out of the 3500 so I subtract it... and 300 per car ,so I divide it , so that I can get the amount of car he needs to sell to get 3500

The inequality representing the minimum number of cars David needs to sell to earn at least $3,500 per month is x>=10, with x being the number of cars sold.

To determine the inequality for the number of sales David needs to make to earn a minimum of $3,500 per month, we consider his monthly income which includes a base salary and commission for cars sold. David earns a base salary of $750 plus a commission of $300 for each car he sells. Let's denote the number of cars David sells in a month as x.

The total monthly income David gets from commission by selling x cars is $300x. So, the total monthly income David earns is $750 (base salary) plus $300x (commission from sales), or $750 + $300x in total.

Since David needs to earn at least $3,500 monthly, his total monthly income must be greater than or equal to $3,500. We can represent this as the following inequality:

$750 + $300x >=$3,500

To find the minimum number of cars David needs to sell, we now solve for x:

Since David cannot sell a fraction of a car, he needs to sell at least 10 cars to meet his financial goal.

Therefore, the inequality for the number of sales David needs to make at least $3,500 per month is x >=10.

Answer:

a. A dog's tail will wag differently in response to positive stimuli and to negative stimuli.

Step-by-step explanation:

A research hypothesis is a proposition that can be tested about the possible outcome of a study based on different stimuli.

A research hypothesis is a specific, clear, and testable proposition or predictive statement about the possible outcome of a scientific research study based on a particular property of a population, such as presumed differences between groups on a particular variable or relationships between variables.

Before a quantitative study takes place, it is important to state the research hypothesis because it is very important to the study.

There is usually an expectation or predicted outcome of the study because the research is determined by the hypothesis.

So it was already hypothesised that a dog would wag its tail in a preferred direction when it is faced with negative or positive stimuli. So the hypothesis was tested as different sets of dogs were placed in a cage and introduced to different stimuli.

From the observation of the researchers, all the dogs wagged their tails to the right when they saw a familiar face (positive stimuli) and wagged their tails to the left when they faced an aggressive dog (negative stimuli)

Step-by-step explanation:

Nasim is making hot sauce. Nasim puts in chile peppers and tomatoes in a ratio of 1 to 3.

Assuming Nasim puts in 9 tomatoes, the number of chile peppers should she put will be:

Ratio of chile peepers to tomato= 1;3

Since she put 9 tomatoes, chile peppers= (1×9)/3 = 9/3 = 3.

For 1 chile peeper, there'll be 3 tomatoes.

For 3 chile pepper, thee will be 9 tomatoes.

Answer: She needs to add 3 chile peppers.

Step-by-step explanation:

The ratio of chile peppers to tomatoes is 1:3

this means that for each 3 tomatoes, she puts one chile pepper.

Then if she puts 9 tomatoes, this means that she puts 3 tomatoes 3 times.

And we know that for each 3 tomatoes she needs to add 1 chile pepper, then she needs to add 1 chile pepper 3 times:

3*1 = 3 chile peppers.

She needs to add 3 chile peppers.

Using the formula of z=(x-mean)/standard deviation. You get a z score of -1. Given the Empirival rule, 68% of all the values fall within 1 standard deviation. So the remaining 32% of values fall outside of this range. Since we have a negative 1, we only care about the lower half or 16%.

Answer: the initial amount is $941.6

Step-by-step explanation:

We would apply the formula for determining compound interest which is expressed as

A = P(1 + r/n)^nt

Where

A = total amount in the account at the end of t years

r represents the interest rate.

n represents the periodic interval at which it was compounded.

P represents the principal or initial amount deposited

From the information given,

A = $1000

r = 1% = 1/100 = 0.01

n = 12 because it was compounded 12 times in a year.

t = 6 years

Therefore,.

1000 = P(1 + 0.01/12)^12 × 6

1000 = P(1 + 0.00083)^72

1000 = P(1.00083)^72

1000 = 1.062P

P = 1000/1.062

P = $941.6
