Find The Arc Length Of The Semicircle

Answers

Answer 1
Perimeter of circle:2*pi*r
r=5
We want half of the perimeter.
2*pi*5/2
=5*pi
Answer 2

Answer:

Arc length of Semicircle ⇒ 5π

Step-by-step explanation:

See procedure below;

Radius of Semicircle ⇒ 5 units,

Diameter of Semicircle ⇒ 2 * 5 = 10 units,

Now if we were to imagine a complete circle, the length of this arc would be half of the circumference of the complete circle provided it ∈ to a semicircle. Therefore, if we are to calculate the length of the circumference of the complete circle given the diameter to have a length of 10, we can divide this by two to receive the arc length of the semicircle;

Circumference of Complete Circle ⇒ πd ⇒ 10π,

Arc length of Semicircle ⇒ 10π / 2 = 5π;

Answer; Arc length of Semicircle ⇒ 5π

Answers

Answer: -8

Step-by-step explanation: First, substitute 8 for y and then solve the remainder of the problem.

                                             -4x - 8 = 24

                                             -4x - 8 + 8 = 24 + 8

                                             -4x = 32

                                             -4x/-4 = 32/-4

Find the value of .

Answers

Answer: 25

Step-by-step explanation: In this problem, we're given a diagram and were asked to find the value of x.

Since the two lines in the figure intersect, we know that they form vertical angles and remember that vertical angles are always congruent, or of equal measure.

Therefore, since we know that one angle measures 75° and the other angles measures 3x°, we can setup the equation 75 = 3x.

To get x by itself since 3 is being multiplied by x,

divide both sides of the equation by 3.

On the left, 75 divided by 3 is 25

and on the right, the 3's cancel.

So the value of x in the diagram shown is 25.

Which expression is a difference of squares with a factor of 2x + 5

Answers

[tex]4x^2-25[/tex] is a difference of squares with a factor 2x+5

because when we factorize [tex]4x^2-25[/tex] we get [tex](2x-5)(2x+5)[/tex]

The expression is a difference of squares with a factor of 2x + 5 [tex]$4 x^{2}-25$[/tex].

What is the Difference of squares formula?

Given:

2x + 5

To find:

The expression is a difference of squares with a factor of 2x + 5.

Step 1

The difference of squares formula is given by

[tex]$(a+b)(a-b)=a^{2}-b^{2}$$[/tex]

We have been given that one factor is 2x + 5.

Hence, [tex]$\mathbf{a}=\mathbf{2 x}, \mathbf{b}=\mathbf{5}$[/tex]

Step 2

It means that the other factor must be (a - b) = (2x - 5)

Hence, in order to expression, we can multiply the factors.

(2x + 5)(2x - 5)

Step 3

Using the difference of squares formula

(2x + 5)(2x - 5)

[tex]$&=(2 x)^{2}-5^{2} \\[/tex]

[tex]$&4 x^{2}-25[/tex]

The required expression exists [tex]$4 x^{2}-25$[/tex].

Therefore, the correct answer is [tex]$4 x^{2}-25$[/tex].

Which function has the greater slope and what does it indicate?

Answers

Answer:

The math function has the greater slope, which shows that the estimated time per question for math is greater than the estimated time per question for language arts.

OR B on edge

Step-by-step explanation:

The cauliflower function has the greater slope, which shows that the cost per pound of cauliflower is increasing at a faster rate than the cost per pound of broccoli.

What is Slope?

A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the

change in y coordinate with respect to the change in x coordinate as,

m = Δy/Δx where, m is the slope

First, Slope for Broccoli

Slope = (3.6 - 3) / (3 - 2.5)

Slope = 0.6 / 0.5

Slope = 1.2

Second, Slope for Cauliflower

slope = (4.50 - 2.75) / (4.5 - 2.75)

= 1.75 / 1.75

= 1.000

Since the slope of the cauliflower function (1.0000) is greater than the slope of the broccoli function (0.8364), we can conclude that the cauliflower function has the greater slope.

Tonya sells make-up part-time. She is paid a monthly commission. She receives 18% for the first $500 she sells and 22% for the balance. She made $356.42 in commission. How much did she sell in make-up?

Answers

Answer:

She sold $1,711 in make-up.

Step-by-step explanation:

She sold x.

For the first $500, she gets 18% = 0.18.

For the balance(x - 500), she gets 22% = 0.22.

So her total earnings can be modeled by the following equation:

[tex]E = 0.18*500 + 0.22*(x - 500)[/tex]

[tex]E = 90 + 0.22*(x - 500)[/tex]

She made $356.42 in commission. How much did she sell in make-up?

So

[tex]356.42 = 90 + 0.22*(x - 500)[/tex]

[tex]90 + 0.22x - 110 = 356.42[/tex]

[tex]0.22x = 356.42 + 20[/tex]

[tex]x = \frac{376.42}{0.22}[/tex]

[tex]x = 1711[/tex]

She sold $1,711 in make-up.

A Wallace's giant bee is 1 1/2 inches long. If this bee is four times longer than a worker bee, how
long is the worker bee?
3/8 in.
1/3 in.
1/8 in.
3/10 in.

Answers

Answer:

3/8 in.

Step-by-step explanation:

If the giant bee is four times longer than a worker bee, you'd divide the giant bee's length by 4 to get the worker bee's length. 1.5 ÷4=0.375. 0.375 is equivalent to 3/8. So 3/8 in.

What two numbers have a sum of 191 and a difference of 63? *Hint: Create a system where one equation represents the sum and one equation represents the difference. ​(smaller number) ​ (bigger number)

Answers

Answer:

Step-by-step explanation:

x+y=191 eq(1) & x-y=63 eq(2)

x=63+y then put in the eq(1)

63+y+y=191

2y=191-63

y=64 then put in the eq(2)

x-y=63

x= 63+y

x=63+64

x=127

Answer:

both numbers are 127 and 64

Step-by-step explanation:

x= one of the numbers

191-x= the other number

(191-x)-x=63

191-x-x=63 (combine like terms)

191-2x=63 (rearrange)

191-63-2x (simplify)

128=2x

The diagram shows a regular pentagon, ABCDE, a regular octagon, ABFGHIJK, and an isosceles triangle, BCF. Work out the angle x

Answers

Answer:

x is 31.5°

Step-by-step explanation:

Here, we have each interior angle of a regular octagon = 135°

Each interior angle of a regular pentagon = 108°

Therefore, 135° + 108° + ∡B = 360°

Hence, ∡B = 360° - (135° + 108°) = 117°

Since, AB = BC = BF ( sides of a regular polygons (octagon and pentagon))

Hence, ΔCBF is an isosceles triangle and ∡x = ∡CFB  from which we have;

∡x + ∡CFB + 117° = 180°

∴  ∡x + ∡CFB = 180° - 117° = 63°

Hence, ∡x = 63° - ∡CFB = 63° - ∡x which gives

2·∡x = 63°

Hence, ∡x = 63°/2 = 31.5°

∡x = 31.5°.

Scientists mixed local bees with African ones to create a bee that would make more honey. They ended up with something much different. The new bees evolved in unexpected ways. They multiplied and migrated north. These Africanized honeybees are now known as killer bees for several scary but legitimate reasons.Killer bees are far more aggressive than their relatives. They have been known to attack in great numbers, even when there has been no direct threat on their hives. They have swarmed because of loud noises, dark clothing, bright jewelry, and even strong perfume. They will chase a person for more than a quarter of a mile and remain angered for up to 24 hours.Killer bees are also dangerous because of their sting. While most bees take up to 30 seconds to attack, killer bees sting in just 3 seconds. Their venom is no stronger than a regular bee's, but when one killer bee stings, others follow. With up to 80,000 members in a colony, victims are quickly overwhelmed. So many stings in such a short time can cause allergic reactions. Victims enter a state of shock, lose blood pressure, and in many cases, die.A final reason why "killer" has been added to their name is the unfortunate number of deaths they have caused. Experts estimate that the Africanized honeybee moves at a rate of about 200 miles each year. As the bees claim new territory, they claim new victims as well. More than 1000 people have been stung to death in South and Central America. There have been rising numbers of attacks in Mexico and a handful in the United States. Once a swarm sets sights on a victim, it is very difficult for the victim to escape. Once attacked, it is very difficult to survive.Thankfully, there has been no killer bee invasion as some once predicted. Although there is no need for panic, the threat of the killer bee is real and should be taken seriously. It is good practice to call a professional to remove beehives in your area. If you are stung multiple times by any insect, you should always seek medical attention. You may not be expert enough to tell the difference between a killer bee and a less dangerous one, so be smart. It is better to be safe than sorry.Which details relate to the main fact in the third paragraph?A. Killer bees attack in great numbers. They swarm for many reasons. They chase people and stay angry for hours.B. Killer bees have very aggressive behavior. Their stings are very dangerous. They have caused many deaths.C. Killer bees sting in just three seconds.
