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

(x + 3)² − 5 = x² +6x+9 -5 =x²+6x+4

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]

Answer:

The solution for x and y in (2x - 1) + (3y + 2)i = 5 – 4i cannot be determined.  

Solution:

From question, the equation given is

(2x - 1) + (3y + 2)i = 5 – 4i

Multiplying the terms inside the bracket (3y + 2) with i, the above equation becomes,

(2x – 1) + 3iy + 2i = 5 – 4i  

Removing the parenthesis in (2x – 1), the above equation becomes,

2x -1 + 3iy + 2i = 5 - 4i

2x – 1 + 3iy + 2i – 5 + 4i = 0  

Rearranging the terms, the above equation becomes

2x + 3iy + 4i + 2i -1 -5 = 0

2x + 3iy + 6i – 6 = 0

The above equation cannot be simplified further. Hence the solution for x and y cannot be determined.

Andre's Mistake in reasoning is assuming that 7 4/8 is equal to 7 1/2. Drawing a number line can prove that the fractions may be equivalent, but the whole numbers are not.

Andre made a mistake in his reasoning.

He incorrectly assumed that 7 4/8 is equal to 7 1/2. The fractions 4/8 and 1/2 are actually equivalent, but the whole numbers 7 and 7 are not.

To prove this, you can draw a number line and divide it into equal parts.

Taking the fractions 4/8 and 1/2, you will see that they represent the same distance, but they start at different points on the number line.

Therefore, 5 3/4 + 2 1/4 is not equal to 7 1/2.

Answer:

The Answer is 4

Step-by-step explanation:

75 Miles divided by 5 Gallons is 15. Take that and divide 60 miles by 15. Your answer is 4 Gallons.

Hank's pickup consumes gas at a rate of 15 miles per gallon. To travel 60 miles, it would need 4 gallons of gas.

To solve this problem, you need to first establish the rate of gas consumption for Hank's pickup. According to the data given, we know that Hank's pickup travels 75 miles with 5 gallons of gas which gives us a rate of 15 miles per gallon. The next step is to find out how much gas Hank's pickup will consume to travel 60 miles. So you divide the 60 miles by the rate of consumption which is 15 miles per gallon. The result is 4 gallons. Therefore, Hank's pickup will need 4 gallons of gas to travel 60 miles.

Answer:

Step-by-step explanation:

0.000000018 = 1.8 * 10^-8

Final answer:

To express the number 0.000000018 in scientific notation, it is written as 1.8 × 10⁻⁸. Additionally, to multiply 0.00000000552 by 0.0000000006188 in scientific notation, the result is 3.415776 × 10⁻¹⁸.

Explanation:

To express the number 0.000000018 in scientific notation, we need to place the decimal after the first non-zero digit, and then count the number of places the decimal has moved. In this case, we move the decimal to the right of the 1 (the first non-zero digit), so it moves 8 places to the right. Therefore, 0.000000018 can be expressed as 1.8 × 10⁻⁸.

For the additional exercise, we'll convert each number to scientific notation and then multiply them:

Now, multiplying these we get:

5.52 × 10⁻⁹ × 6.188 × 10⁻¹⁰ = 34.15776 × 10⁻¹⁹ which simplifies to 3.415776 × 10⁻¹⁸ in scientific notation.

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

A)

5x+y=13

−x+2y=−7

Multiply each  term in the first equation by -2:

5x + y = 13 x -2 = -10x - 2y = -26

Now add that to the second equation:

-10x - 2y = -26 + −x+2y=−7

= -11x = -33

Divide each side by -11

X = -33 / -11

X = 3

Now you have x, replace it in the first equation and solve for y:

5(3) + y = 13

Simplify:

15 + y = 13

Subtract 15 from both sides:

y = 13 -15

y = -2

Solution = (3,-2)

B)

4x+5y=35

−3x+2y=−9

Multiply each term in the second equation by -2.5:

7.5x -5y = 22.5

Add this to the first equation:

4x+5y=35  + 7.5x -5y = 22.5

= 11.5x = 57.5

Divide both sides by 11.5:

x = 57.5 / 11.5

x = 5

Now you have x, replace x in one of the equations to solve for y:

4(5) + 5y = 35

Simplify:

20 + 5y = 35

Subtract 20 from both sides:

5y = 15

Divide both sides by 5:

y = 15/5

Answer:

There are 13,782.47 feet in 4.2 kilometers ⇒ answer A

Step-by-step explanation:

- Cilia cycles 4.2 km every morning

- We need to convert the kilometers to feet

- 1 mile = 1.609 kilometers

- 1 mile = 5,280 feet

* Lets do that

∵ 1 mile = 1.609 km

∵ 1 mile = 5,280 feet

- Equate them

∴ 1.609 km = 5, 280 miles

* Now we can use the cross multiplication to find how many feet in

 4.2 kilometers

→    km       :    feet

→   1.609    :    5,280

→   4.2        :    x

- By using cross multiplication

∴ 1.609 x = 4.2 × 5,280

- Multiply 4.2 by 5,280

∴ 1.609 x = 22176

- Divide both sides by 1.609

∴ x = 13782.47

∵ x represents the number of feet in 4.2 kilometers

∴ There are 13,782.47 feet in 4.2 kilometers

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:

x = -4, y = 8.

Step-by-step explanation:

Question 16.

8x + y = -24    ........(A)

-3x - 2y = -4    ........(B)

Multiply (A) by 2:

16x + 2y = -48   Adding this to equation (B):

13x = -52

x = -4

Substituting this value of x in Equation (A):

8(-4) + y = -24

y = -24 + 32 = 8.

Answer:

Answer for the first part of question 16 is y =-24 - 8x

1st subtract 8x from both sides: 8x + y - 8x = -24 - 8x

2nd simplify: -24 - 8x

Answer for the 2nd part of Q. 16 is y = -(-4+3x)/2

1st add 3x to both sides: -3x - 2y + 3x = -4 + 3x

2nd simplify: -2y = -4 + 3x

3rd divide both sides by -2: -2y ÷ -2 = 4 ÷ -2 +3x ÷ -2

4th simplify: (-4 + 3x)/2

Answer to the 1st part of Q. 17 is y = (-1 - 2x)/3

1st subtract 2x from both sides 2x + 3y - 2x = -1 - 2x

2nd simplify: -3y= -1 - 2x

3rd divide both sides by -3: -3y ÷ -3 = 1 ÷ -3 - 2x ÷ -3

4th simplify: y = (-1 - 2x)/3

Answer to 2nd part of Q.17: y = 6 + 7x ÷ 10

1st Add 7x to both sides: -7x + 10y + 7x = 6 + 7x

2nd simplify: 10y=6+7x

3rd divide both sides by 10: 10y ÷ 10 = 6 ÷ 10 + 7x ÷ 10

4th simplify: y = 6 + 7x ÷ 10

Answer:

Step-by-step explanation:

its been 3 years.  did u figure it out?

To write a percent as a decimal, first remember that a percent is a ratio that compares a number to 100. Let's say we wanted to convert 82% to a decimal. We can think of 82% as the ratio 82 to 100 or 82 ÷ 100. When we divide by 100, it moves the decimal point 2 places to the left so 82 ÷ 100 would move the decimal point 2 places to the left which would give us .82. Therefore, 82% would = 0.82.

Final answer:

To convert a percent to a decimal, represent the percent as a fraction with a denominator of 100 and divide the numerator by the denominator. A percent is a ratio whose denominator is 100, making this conversion straightforward.

Explanation:

To change a percent to a decimal, you need to express the percent value as a fraction with a denominator of 100. For example, if you have a percent like 75%, you represent it as the fraction 75/100. Then, you divide the numerator by the denominator, which in this case is 75 divided by 100, giving you a decimal of 0.75.

When calculating percents, it's essential to understand that a percent is a ratio with a denominator of 100. So every percent can be written as a fraction over 100, simplified if possible, and then easily converted to a decimal.

To illustrate the reverse process, for converting a decimal to a percent, you'd take a decimal such as 0.45, write it as the fraction 45/100 (which is already simplified since the denominator is 100), then express it as a percent, which would be 45%.

Answer:8

Step-by-step explanation:

Divide the amount of money she has by the amount the bottles cost. And you will get 8! Check your answer by multiplying 8 by 22.87

Final answer:

Nidhi can buy a maximum of 8 bottles of wine with her $185 budget, as each bottle costs $22.87.

Explanation:

The question involves finding out the maximum number of bottles of wine Nidhi can buy with her budget of $185, given that each bottle costs $22.87. To find the answer, we need to divide the total amount of money Nidhi has by the cost of one bottle of wine.

Step 1: Calculate the total number of bottles by dividing the total budget by the cost per bottle:

Total Number of Bottles = Total Budget / Cost per Bottle
Total Number of Bottles = $185 / $22.87

Step 2: Perform the calculation:

Total Number of Bottles ≈ 8.09

Since Nidhi cannot buy a fraction of a bottle, she can purchase a maximum of 8 bottles of wine with her budget of $185.
