Answer:

3 and 4

Step-by-step explanation:

Consider squares on either side of 15, that is 9 and 16, so

[tex]\sqrt{9}[/tex] < [tex]\sqrt{15}[/tex] < [tex]\sqrt{16}[/tex], that is

3 < [tex]\sqrt{15}[/tex] < 4

Answer:

[tex]3<\sqrt{15}<4[/tex]

Step-by-step explanation:

We are asked to find the integers such that square root of 15 lies between them.

We know that perfect square less than 15 is 9 and perfect square greater than 15 is 16.

We can represent this information in an inequality as:

[tex]\sqrt{9}<\sqrt{15}<\sqrt{16}[/tex]

[tex]\sqrt{3^2}<\sqrt{15}<\sqrt{4^2}[/tex]

[tex]3<\sqrt{15}<4[/tex]

Therefore, the square root of 15 lies 3 and 4.

The ratio of cranberry juice to apple juice to orange juice, when the drink consists of 1/3 apple juice and 1/2 orange juice, is 1:2:3.

The student asked for the ratio of cranberry juice to apple juice to orange juice in its simplest form, knowing that 1/3 of the drink is apple juice and 1/2 is orange juice. To find the fraction of the drink that is cranberry juice, we subtract the other two parts from the whole (which is 1):

1 - (1/3 + 1/2) = 1 - (2/6 + 3/6) = 1 - 5/6 = 1/6

So the ratio of cranberry juice to apple juice to orange juice can be written as:

Cranberry : Apple : Orange = 1/6 : 1/3 : 1/2

To compare ratios, we need to have the same denominator. Multiplying each part of the ratio by 6 (the least common multiple of 6, 3, and 2) gives us:

Cranberry : Apple : Orange = 1 : 2 : 3

Therefore, the ratio of cranberry juice to apple juice to orange juice in its simplest form is 1:2:3.

Answer:

The original cost of the pair of shoes before tax is $48.95

Step-by-step explanation:

* Lets explain how to solve the problem

- Assume that the cost of the pair of shoes is 100% before taxes

∵ The cost of the pair of shoes is 100% before taxes

∵ The tax is 7.25%

∴ The price of the pair of shoes after tax = 100% + 7.25% = 107.25%

- This 107.25% equivalent to the price of the pair of shoes including

  the tax

∵ The cost of the pair of shoes including tax is $52.50

- Lets use the cross multiplication to find the cost of the pair of

 shoes before  tax

∵     100%  ⇒  107.25%

         ?       ⇒  52.50

- ? represents the cost of the pair of shoes before tax

∴ ? = [tex]\frac{100*52.50}{107.25}=48.95[/tex]

∴ The original cost of the pair of shoes before tax is $48.95

Answer:

B) [tex](x + 3)^2 - 5[/tex]

Step-by-step explanation:

the equation is: [tex]x^2 + 6x + 4[/tex]

we have an equation of the form

[tex]ax^2+bx+c[/tex]

where

[tex]a=1,b=6,c=4[/tex]

and we must complete the square to obtain a perfect square binomial,

we must add and substract the following:

[tex](\frac{b}{2a} )^2[/tex]

which is:

[tex](\frac{6}{2*1} )^2=3^2[/tex]

and then the equation becomes:

[tex]x^2 + 6x + 4+3^2-3^2[/tex]

where the terms [tex]x^2+6x+3^2[/tex] are the components of the perfect square binomial: [tex](x+3)^2[/tex]

and thus, the equation now is:

[tex](x+3)^2+4-3^2\\=(x-3)^2+4-9\\=(x+3)^2-5[/tex]

the answer is: B) [tex](x + 3)^2 - 5[/tex]

Equality Properties

Algebra I

Step-by-step explanation:

Step 1: Define

-8 - 3(w + 13) = 4(w + 11) - 7w

Step 2: Solve for w

Here we see that -47 does not equal 44.

∴ w = no solutions.

There is no solution to the equation -8-3(w+13)=4(w+11)-7w, as it simplifies to an untrue statement.

Here is the step-by-step solution:

Distribute the constants through the parentheses:

-8 - 3w - 39 = 4w + 44 - 7w

Combine like terms:

-47 - 3w = -3w + 44

Since -3w on both sides cancels out, we are left with just the constants:

-47 ≠ 44

There is no value for w that will make this equation true, hence there is no solution.

Answer:

About 16 centimeters

Step-by-step explanation:

In order to convert inches to centimeters, you must multiply the inches by 2.54. Then, round your answer, and you will get 16.

1) 6.14 * 2.54 = 15.5956

2) = 16

The length of a dollar bill is approximately 16 centimeters when converted from inches and rounded to the nearest whole number.

To convert the length of a dollar bill from inches to centimeters, we use the conversion factor 1 inch = 2.54 cm. The length of the dollar bill is 6.14 inches. To find the length in centimeters, we multiply 6.14 inches by the conversion factor.

Step 1: Set up the conversion equation:
Length in cm = Length in inches x Conversion factor

Step 2: Substitute the given length and conversion factor:
Length in cm = 6.14 inches x 2.54 cm/inch

Step 3: Carry out the multiplication:
Length in cm = 15.5956 cm

So, the approximate length of a dollar bill to the nearest centimeter is about 16 cm, when rounded to the nearest whole number.

Answer:

24,12,6

Step-by-step explanation:

48 is even, so you can factor out 2, your first prime factor

Final answer:

The prime factors of 48 are 2 to the power of 4 and 3. You divide 48 by 2 repeatedly until only prime numbers are left, which are 2´ and 3.

Explanation:

Finding Prime Factors

The prime factors of a number are the prime numbers that multiply together to equal the original number. To find the prime factors of 48, you start by finding the smallest prime number that divides 48. In this case, it would be 2. So, you divide 48 by 2 to get 24. You then repeat this process until you are only left with prime numbers.

Here's a step-by-step breakdown:

48 ÷ 2 = 24

24 ÷ 2 = 12

12 ÷ 2 = 6

6 ÷ 2 = 3

Now, you're left with 2, 2, 2, 2, and 3, all of which are prime numbers. So the prime factors of 48 are 2´ (2 raised to the power of 4) and 3.

Answer:

The quadrilateral is not a rectangle

Step-by-step explanation:

we know that

If a quadrilateral ABCD is a rectangle

then

Opposite sides are congruent and parallel and adjacent sides are perpendicular

Remember that

If two lines are parallel, then their slopes are the same

If two lines are perpendicular, then their slopes are opposite reciprocal (the product of their slopes is equal to -1)

The formula to calculate the slope between two points is equal to

[tex]m=\frac{y2-y1}{x2-x1}[/tex]

we have

A(-5,5), B(1,8), C(4,2), and D(-2,-2)

Plot the figure to better understand the problem

see the attached figure

Find the slope of the four sides and then compare

step 1

Find slope AB

A(-5,5), B(1,8)

substitute in the formula

[tex]m=\frac{8-5}{1+5}[/tex]

[tex]m=\frac{3}{6}[/tex]

[tex]m_A_B=\frac{1}{2}[/tex]

step 2

Find slope BC

B(1,8), C(4,2)

substitute in the formula

[tex]m=\frac{2-8}{4-1}[/tex]

[tex]m=\frac{-6}{3}[/tex]

[tex]m_B_C=-2[/tex]

step 3

Find slope CD

C(4,2), and D(-2,-2)

substitute in the formula

[tex]m=\frac{-2-2}{-2-4}[/tex]

[tex]m=\frac{-4}{-6}[/tex]

[tex]m_C_D=\frac{2}{3}[/tex]

step 4

Find slope AD

A(-5,5), D(-2,-2)

substitute in the formula

[tex]m=\frac{-2-5}{-2+5}[/tex]

[tex]m=\frac{-7}{3}[/tex]

[tex]m_A_D=-\frac{7}{3}[/tex]

step 5

Verify if the opposites are parallel

Remember that

If two lines are parallel, then their slopes are the same

The opposite sides are

AB and CD

BC and AD

we have

[tex]m_A_B=\frac{1}{2}[/tex]

[tex]m_C_D=\frac{2}{3}[/tex]

so

[tex]m_A_B \neq m_C_D[/tex]

It is not necessary to continue verifying, because two of the opposite sides are not parallel

therefore

The quadrilateral is not a rectangle

Answer:

option D is correct

the collection of all points on the same plane located 12cm from point Q

Answer:

Option D is correct

Step-by-step explanation:

A circle is a planar shape which has a point called center. All the points on the circle keep equal distance from the centre and the equal distance is called radius.

Here given that radius is 12 cm.  Since it is a circle it should be in a plane only.  Otherwise this will form a sphere.  So this lies in a plane with all points keeping equal distance of [tex]12 cm[/tex] from the center

Option D) the collection of all points on the same plane located 12 centimeters from point Q
