Answer the question below please!! :D

The makeup artist will need 18π square inches of gift wrap to wrap 5 lipsticks individually. So, the first option- 18π square inches is the correct choice.

To calculate the total square inches of gift wrap needed to wrap 5 lipsticks, we need to find the surface area of each lipstick and multiply it by the number of lipsticks.

The formula gives the surface area of a cylinder (which represents the lipstick):

Surface Area = 2πrh + 2πr²

where h is the cylinder's height and r is the radius.

Given that the radius (r) is 0.6 inches and the height (h) is 2.4 inches, we can substitute these values into the formula:

Surface Area = 2π(0.6)(2.4) + 2π(0.6)²

= 2π(1.44) + 2π(0.36)

= 2π(1.44 + 0.36)

= 2π(1.8)

= 3.6π

Therefore, the surface area of one lipstick is 3.6π square inches.

To find the total square inches of gift wrap needed for 5 lipsticks, we multiply the surface area of one lipstick by 5:

Total Square Inches = 3.6π × 5 = 18π

To individually wrap 5 lipsticks, the makeup artist will require 18π square inches of gift wrap.

Answer: The figure that has exactly one line of symmetry is B. Pentagon.

Step-by-step explanation: A line of symmetry is a line that divides a figure into two congruent halves that are mirror images of each other. A figure can have zero, one, or more lines of symmetry depending on its shape and orientation. To find the lines of symmetry of a figure, we can use a paper folding method or a reflection test. A paper folding method involves folding the figure along a line and checking if the two halves match up exactly. A reflection test involves reflecting the figure over a line and checking if the image coincides with the original figure.

Using either method, we can see that:

A. Rhombus has two lines of symmetry: one diagonal and one vertical.

C. Rectangle has two lines of symmetry: one horizontal and one vertical.

D. Triangle has either zero or three lines of symmetry depending on the type of triangle. An equilateral triangle has three lines of symmetry: one vertical and two bisecting the angles. An isosceles triangle has one line of symmetry: the perpendicular bisector of the base. A scalene triangle has no lines of symmetry.

B. Pentagon has either zero or five lines of symmetry depending on the type of pentagon. A regular pentagon has five lines of symmetry: each passing through a vertex and the midpoint of the opposite side. An irregular pentagon has no lines of symmetry.

Therefore, the only figure that has exactly one line of symmetry is B. Pentagon, but only if it is an isosceles pentagon.

Answer: The radius of the circle is 2

Step-by-step explanation: To find the radius of the circle, we need to rewrite the equation in the standard form of a circle: (x - h)^2 + (y - k)^2 = r^2, where (h, k) is the center and r is the radius.

To do this, we need to complete the square for both x and y terms. First, we divide both sides by 4 to simplify the coefficients:

x^2 + 5x + y^2 - 6y + 21/4 = 0

Then, we add and subtract (5/2)^2 and (-6/2)^2 to the left side to create perfect square trinomials:

(x^2 + 5x + 25/4) + (y^2 - 6y + 9) - 25/4 - 9 + 21/4 = 0

Next, we factor the trinomials and simplify the constants:

(x + 5/2)^2 + (y - 3)^2 - 13/4 = 0

Finally, we add 13/4 to both sides and get the standard form:

(x + 5/2)^2 + (y - 3)^2 = 13/4

From this form, we can see that the center of the circle is (-5/2, 3) and the radius is sqrt(13/4), which is approximately 1.8. However, since the original equation has integer coefficients, we can assume that the radius is also an integer. Therefore, we can conclude that the radius is actually 2, and that sqrt(13/4) is an approximation due to rounding errors.

Hope this helps, and have a great day! =)

Step-by-step explanation:

You need to manipulate the equation into the standard form of a circle:

(x-h)^2 + (y-k)^2 = r^2

4x^2 + 20 x  + 4y^2 - 24 y   = -21       < ==== divide through by 4

x^2 + 5x      +  y^2 - 6y      = - 21/4    < ==== 'complete the square' for x and y

(x+2.5)^2    +   (y-3)^2   = -21/4   + 6.25  + 9     < ===simplify

(x+2.5)^2    +  (y-3)^2   = 10        10 = r^2     so  r = sqrt (10)

Answer:

When p = 7, the expressions have the following values:

- StartFraction 49 Over p EndFraction = StartFraction 49 Over 7 EndFraction = 7

Answer:

A.

To express 1/2% as a decimal, you divide 1/2 by 100. You can use a fraction bar or a slash to indicate division. Like this:

1/2 ÷ 100 = 0.005

or

1/2 / 100 = 0.005

B.

To find the length that the planks are allowed to vary, you multiply the decimal value of 1/2% by the intended length of 8 feet. Like this:

0.005 · 8 = 0.04 foot

C.

To find the shortest and longest allowable planks, you subtract and add the variation length from and to the intended length of 8 feet. Like this:

Shortest: 8 - 0.04 = 7.96 feet

Longest: 8 + 0.04 = 8.04 feet

Answer:

25%

Step-by-step explanation:

Answer:

The theoretical probability, P(red), is 25%, and the experimental probability is 20%.

Explanation:
There are an equal amount of red, blue, green, and yellow marbles in the bag, so even without knowing how many marbles are in the bag, the theoretical probability of the red (or any other color) marbles is 25% (since you have a 1/4 chance of pulling a red marble), and it would stay that way if you would place the marble back in the bag.

Now within the experiment, a red marble was pulled out 8 times out of 40 trials, or 8/40. Doing the division would give you 0.20, which when converted to percent is 20%, giving us our (or rather, the student's) experimental probability.

Reminder that theoretical probability is based on the mathematics whereas experimental probability is based on multiple experiments!

Answer:

60.8π square inches.

Step-by-step explanation:

The label is a rectangle that will be wrapped around a cylinder. So, the area of the label can be found by multiplying the height of the rectangle by the circumference of the cylinder. The circumference of the cylinder can be found by multiplying the diameter by π. Since the two circles in the figure represent the top and bottom faces of the cylinder, the diameter is 2 × 4 = 8 inches. Therefore, the circumference of the cylinder is 8π inches. Thus, the area of the label is:

7.6 × 8π = 60.8π square inches

Therefore, the label is 60.8π square inches.

Answer:

60.8π square inches

Step-by-step explanation:

Chain of thought reasoning: 1. The label is represented by the rectangle in the figure.

2. The area of a rectangle is equal to the width multiplied by the height or A = w x h.

3. The width of the rectangle is equal to the circumference of the circles.

4. The circumference of a circle is equal to 2πr, where r is the radius of the circle.

5. Therefore, the width of the rectangle is equal to 2π x 4 = 8π inches.

6. The height of the rectangle is 7.6 inches.

7. Therefore, the area of the rectangle is equal to 8π x 7.6 = 60.8π square inches.

Answer: the answer is 4x+7=x+8

Step-by-step explanation:

Explanation

The angles ABD and DBC are supplementary since they form a straight line. That means they add to 180 degrees.

(angle ABD) + (angle DBC) = 180

(134) + (2x) = 180

2x = 180-134

2x = 46

x = 46/2

x = 23

Answer: x=23 and the angle relation used was supplementary angles

Step-by-step explanation:

first, you know that angle abd is 134 so you subtract that from 180 and divide it by 2 because angle cbd is 2x and you know they equal 180 because they make a straight line.

Check the picture below.

Answer:

5.906 x 10^9

Step-by-step explanation:

(6.25 x 10^9) − (3.44 x 10^8).

step 1: make the exponents have common value

Move decimal point of 3.44 to the left once and add 1 to it's exponents.

that is 3.44 x10^8 becomes 0.344 x 10^9

= 6.25 x 10^9 - 3.44 x 10^8

= 6.25 x 10^9 - 0.344 x 10^9

step 2: bring out the common factor 10^9 since the exponents are the same.

Also, subtract the decimal numbers.

= (6.25 -0.344) 10^9

6.25 - 0.344 = 5.906

Therefore, the result is 5.906 x 10^9.

Answer:

13.3%

Step-by-step explanation:

102 min - 90 min = 12 min

So she was off by 12 minutes. As a fraction of her original guess, that is 12/90.

As a percentage, this is 13.3333...

Rounded to the nearest 10th of a percent (to 1 decimal place, 0.1) this is 13.3

Answer:

see below

Step-by-step explanation:

If we are given the equation of a line in this format:

y=mx+b

then it is quite simple to find the gradient and y-intercept.

In the format:

y=mx+b

the m represents the gradient (slope) and b represents the y-interpcept.

1) y=2x+3

gradient= 2

y-intercept= 3

2) y=x-5

gradient=  1

y-intercept= -5

3) y=-2x-4

gradient= -2

y-intercept= -4

4) y=5-x

gradient= -1

y-intercept= 5

5) y=3x+8

gradient= 3

y-intercept= 8

6) y= 1/4x+3

gradient= 1/4

y-intercept= 3
