Answer:

The bedroom closet will measure 2 feet by 3 feet.

Step-by-step explanation:

A blueprint of a bedroom has a scale of 1/4 inch is equivalent to 1 foot

[tex]\frac{1}{4}[/tex] inch= 1 foot

We need to convert 1/2 inch is how many foot

[tex]\frac{\frac{1}{2}}{\frac{1}{4} } =\frac{1}{2} \cdot \frac{4}{1} =2[/tex]

We need to convert 3/4 inch is how many foot

[tex]\frac{\frac{3}{4}}{\frac{1}{4} } =\frac{3}{4} \cdot \frac{4}{1} =3[/tex]

1/2 inch is 2 feet

3/4 inch is 3 feet

The bedroom closet will measure 2 feet by 3 feet.

Answer:  The required constant of proportionality is 10.

Step-by-step explanation:  Given that y is directly proportional to x, and y = 150 when x = 15.

We are to find the constant of proportionality.

According to the given information, we can write

[tex]y\propto x\\\\\Rightarrow y=kx~~~~~~~~~~~~~~~~[\textup{where k is the constsnt of propotionality}].[/tex]

When y = 150 and x = 15, we get from the above equation that

[tex]y=kx\\\\\Rightarrow 150=k\times15\\\\\Rightarrow k=\dfrac{150}{15}\\\\\Rightarrow k=10.[/tex]

Thus, the required constant of proportionality is 10.

Answer:

4410 cards, 9 albums

Step-by-step explanation:

Number of cards in a box = 315

Number of boxes = 14

b) Total number of cards =  Number of boxes × Number of cards in 1 box

=[tex]315\times 14 = 4410[/tex]

a) Carmella estimated she had 3,000 cards so she bought a 6 album of 500 cards.

No, 6 albums are not enough as she estimated wrong number of cards. There are total of 4410 cards but she estimated it to be 3000 cards.

c) Total number of albums required = [tex]\displaystyle\frac{\text{Total number of cards}}{\text{Number of card 1 album can hold}}[/tex]

[tex]=\frac{4410}{500} = 8.82 \approx 9[/tex]

Thus, she will require 9 albums to put all her cards.

Answer:

a. Number of flour cups needed = 4 cups

b. Number of cookies that can be baked = 240 cookies

Explanation:

We are given that:

1 cup of flour is needed to make 2 dozen cookies

To solve the two parts of this question, we will simply use cross multiplication

Part a:

1 cup of flour .......................> 2 dozen cookies

x cups of flour ....................> 8 dozen cookies

[tex]x = \frac{8*1}{2} = 4[/tex] cups

Therefore, 4 cups of flour are required to make 8 dozen cookies

Part b:

1 cup of flour .................> 2 dozen cookies

10 cups of flour ............> y dozens of cookies

[tex]y=\frac{10*2}{1} = 20[/tex] dozens of cookies

This means that, 10 cups of flour can make 20 dozen cookies

However, here we are asked about the number of cookies, not the number of dozens

We know that 1 dozen contains 12 parts

This means that:

1 dozen cookies = 12 cookies

Therefore:

20 dozens cookies = 20 × 12 = 240 cookies

Hope this helps :)

Answer:

Write the formula for one measurement, then solve the formula for the different measurement you want to find and use this new formula to find that measurement.

Step-by-step explanation:

 We can understand this through an example.

If we need to find the lenght of a rectangle whose width is 4 feet and whose perimeter is 28 feet, we can use a formula for one measurement to write a formula for a different measurement:

 - We need to write the formula for the perimeter of a rectangle:

[tex]P=2l+2w[/tex]

Where "l" is the lenght and "w" is the width.

- Since we know the width and the perimeter of the rectangle and we need to find the lenght, we can solve for "l":

[tex]P=2l+2w\\\\P-2w=2l\\\\l=\frac{P-2w}{2}[/tex]

Now we get a new formula for calculate a differente measurement (the lenght of the rectangle).

- Substituting values, we get:

[tex]l=\frac{28ft-2(4ft)}{2}=10\ ft[/tex]

Answer:

c

Step-by-step explanation:

Answer:

Step-by-step explanation:

Hello:

the equation is : y = ax+b

the slope is a : a×(2) = -1......( perpendicular to a line with a slope of 2 for : y=2x+1)

a =-1/2          y=(-1/2)x+b

the line that passes through (6, 2) : 2 = (-1/2)(6)+b

b = 5

the equation is :  y  = (-1/2)x+5

You can use the fact that perpendicular lines have slopes such that their multiplication ends up as -1.

The equation of the line perpendicular to line y = 2x + 1 and passing through (6,2) point coordinate is given as

[tex]y = -\dfrac{1}{2}x + 5[/tex]

Suppose that first straight line has slope 's'

Let another straight line be perpendicular to this first line.

Let its slope be 'a'

Then due to them being perpendicular, they have their slopes' multiplication as -1

or

[tex]s \times a = -1\\\\a = -\dfrac{1}{s}[/tex]

If the slope of a line is m and the y-intercept is c, then the equation of that straight line is given as:

[tex]y = mx + c[/tex]

The first line y = 2x + 1 is in slope intercept form and its slope is s = 2

Now, let the second line which is perpendicular to this line and passing through (6,2) coordinate be

y = [tex]ax + b[/tex]

Then as both lines are perpendicular, thus

[tex]a = -\dfrac{1}{s} = -\dfrac{1}{2}[/tex]

Thus, equation of second line is

[tex]y = -\dfrac{1}{2}x + c[/tex]

Since this line passes through coordinate (6,2), thus, this point coordinate should satisfy the equation of line as an equation is true for all points the graph represented by it passes through.

Thus,

[tex]y = -\dfrac{1}{2}x + c[/tex]

[tex]2 = -\dfrac{1}{2} \times 6 + c\\\\2 = -3 +c\\\\c=2+3 = 5[/tex]

Thus, equation of the second line is

[tex]y = -\dfrac{1}{2}x + 5[/tex]

Thus,

The equation of the line perpendicular to line y = 2x + 1 and passing through (6,2) point coordinate is given as

[tex]y = -\dfrac{1}{2}x + 5[/tex]

Answer:

Step-by-step explanation:

we know that

A Rational Number is a number that can be made by dividing two integers

we have

[tex]\frac{\sqrt{2}}{8}[/tex]

[tex]\sqrt{2}[/tex] ----> is not a integer

so

The given number cannot be rewritten as the quotient of two integers

therefore

The given number is irrational

Student A is incorrect because is a irrational number and not all fractions are rational

Student B reasoning is incorrect, because there are fractions that have as numerator an irrational number and can be rational numbers

example

[tex]\frac{\sqrt{2}}{3\sqrt{2}}=\frac{1}{3}[/tex] ----> is a rational number and the numerator is a irrational number

Student A incorrectly claims √2/8 is rational because it can be written as a fraction. Student B is correct, stating that √2/8 is irrational because √2 is irrational, and dividing it by 8 doesn't change its irrationality.

Let's evaluate the reasoning of both students A and B and correct any errors:

Student A:

Student A's reasoning is incorrect. They claim that √2 / 8 is rational because it can be written as a fraction. However, being able to write a number as a fraction doesn't necessarily make it rational. The key point is whether the number can be expressed as a ratio of two integers, and in this case, √2 cannot be expressed as a simple fraction. √2 is known to be an irrational number, and when you divide an irrational number by 8, the result remains irrational.

Student B:

Student B's reasoning is correct. They state that √2 / 8 is irrational because √2 is irrational. This is accurate. The division of an irrational number by a rational number does not change its irrationality. Therefore, √2 / 8 is indeed an irrational number.

In summary, Student B provides the correct reasoning, while Student A's reasoning is flawed.

Answer: b

Step-by-step explanation:

ok, lets see the answers one for one.

a) in this case, t can be 4, if t= 4 then t + 1 = 5 and the inequality is false.

b) in this case, the maximum vale of t is 2, then 2 + 1 = 3, the inequality is true here, and all the other numbers in the set is smaller than 2, then all this set keeps the inequality true.

c and d) both sets allow to take, for example, t= 10, wich makes the inequality false.

now in this type of exercises, you should se the biggest and lowest number that keeps the inequality true, in this case the biggest is 2, because 2 + 1 = 3, and there is no lowest limit because any negative number + 1 will be less than 3. With those limits then you can figure the set of valid solutions with all the numbers in between.

Final answer:

The solution to the inequality 3 ">=" t + 1 is option b) {t | t ">=" 2}, which means that t is any number less than or equal to 2.

Explanation:

Before solving the inequality 3 ">=" t + 1, first, let's isolate the variable t. To do that, we subtract 1 from both sides of the inequality:

3 - 1 ">=" t + 1 - 1

2 ">=" t

This can be read as 't is less than or equal to 2' or 't must be any number that is 2 or smaller.' Therefore, the correct answer is:

{t | t ">=" 2}

When comparing with the question options, it is clear that option b) matches our solution.

Thus, option b) {t | t ">=" 2} is the correct answer to the inequality given in the question.

The measure of ∠ACD is 150°. So the answer is D.150°.

The ∠ACD is an exterior angle of triangle ABC. We can use the fact that the sum of the measures of the interior angles of a triangle is 180° to solve for the measure of ∠ACD.

Identify the interior angles of triangle ABC: We are given the measures of two interior angles: ∠A = 33° and ∠B = 117°.

Find the sum of the interior angles of triangle ABC: ∠A + ∠B + ∠C = 180°

Substitute the known values and solve for ∠C: 33° + 117° + ∠C = 180°

Combine like terms: 150° + ∠C = 180°

Isolate ∠C: ∠C = 180° - 150°

Calculate the measure of ∠C: ∠C = 30°

Find the measure of ∠ACD: Since ∠ACD is an exterior angle of triangle ABC and ∠C is an interior angle, we know that ∠ACD and ∠C are supplementary angles. Therefore, their measures add up to 180°.

Calculate the measure of ∠ACD: ∠ACD = 180° - ∠C = 180° - 30° = 150°

Therefore, the measure of ∠ACD is 150°. So the answer is D. 150°.
