Can a chord be a diameter?

Answers

Answer 1

Answer:

yes

Step-by-step explanation:

ΔABC ~ ΔEFD

Answer 2

Step-by-step explanation:

A diameter satisfies the definition of a chord, however, a chord is not necessarily a diameter. This is because every diameter passes through the center of a circle, but some chords do not pass through the center. Thus, it can be stated, every diameter is a chord, but not every chord is a diameter.Hope this is fine for you

Kelli is searching for a new daycare center for her child. At Lori's Local Daycare, there is a ratio of 2 caretakers for every 7 children. If there are 189 total children, then how many people are at the daycare facility?

Answers

Answer:

243 people

Step-by-step explanation:

Kelli is searching for a new daycare center for her child. At Lori's Local Daycare, there is a ratio of 2 caretakers for every 7 children. If there are 189 total children, then how many people are at the daycare facility?

The ratio is given as:

Caretakers : Children

2 : 7

= In fraction = 2/7

If there are 189 total children, then how many people are at the daycare facility?

Step 1

We calculate the number of caretakers is there are 189 children

7 children = 2 caretakeras

189 children = x

Cross Multiply

7x = 189 × 2

x = 189 × 2/7

x = 54 caretakers

Step 2

The total number of people at the daycare

= 189 children + 54 caretakers

= 243 people

the square root of 1681 is 41

Answer:

Step-by-step explanation:

[tex]9^{2}[/tex] + [tex]40^{2}[/tex] = [tex]c^{2}[/tex]

A coin purse contains d dimes and q quarters. There are 35 coins in the purse, and the total value of the coins is $5.60. Create the system of linear equations and use it to find how many dimes and quarters are in the purse.

Answers

Answer:

14 dimes, 21 quarters

Step-by-step explanation:

Represent dimes with d and quarters with q.

So: 35 coins means

[tex]d + q = 35[/tex]

1 dime = $0.10 and 1 quarter = $0.25. So, a value of $5.60 means

[tex]0.10d + 0.25q = 5.60[/tex]

So, the system of equations is:

[tex]d + q = 35[/tex]

[tex]0.10d + 0.25q = 5.60[/tex]

Make d the subject in [tex]d + q = 35[/tex]

[tex]d = 35 - q[/tex]

Substitute 35 - q for d in [tex]0.10d + 0.25q = 5.60[/tex]

[tex]0.10d + 0.25(35 - q) = 5.60[/tex]

Open bracket

[tex]0.10d + 8.75 - 0.25q = 5.60[/tex]

Collect Like Terms

[tex]0.10d - 0.25q = 5.60 - 8.75[/tex]

[tex]-0.15q = -3.15[/tex]

Solve for q

[tex]q = \frac{-3.15}{-0.15}[/tex]

[tex]q = 21[/tex]

Substitute 21 for q in [tex]d = 35 - q[/tex]

[tex]d = 35 - 21[/tex]

[tex]d = 14[/tex]

ratio of basketballs to jerseys is 8:32 Show your work.

Answers

First, let’s all acknowledge that whoever comes up with problems like this WANTS kids to hate math...smh

I’m sure there is a prettier way to solve this, but here’s what I did:

8(2.25) + 3(22.50) =
18 + 67.50 = 85.50 per “set” of balls/jerseys
400/85.50 = 4.678 = number of “sets” he can buy. Round down to 4 so we have room for tax.

85.5 x 4 “sets”= $342
Tax on 342 is 0.06 x 342 = 20.52

$342 + 20.52 = $362.52 spent

Basketballs = 4 sets x 8 balls per set= 32
Jerseys = 4 sets x 3 jerseys per set= 12

32 basketballs, 12 jerseys, $362.52 spent

Answers

Answer:

The height is 15 cm. The volume is 6000 cm³

Step-by-step explanation:

The base is square, so the sides are equal.

√400 = 20. This is the length and width of the cuboid.

The area of the base and the area of the top face are equal, so we subtract 2(400) from the total area to get the area of the remaining 4 faces.

2000 - 800 = 1200 cm²

Divide by 4 to get the area of an individual face.

1200/4 = 300 cm²

We found the width earlier: 20cm

We found the width earlier: 20cm300/20 = 15cm. This is the height.

To find Volume, multiply Area of the base times the height:

400cm²×15cm = 6000cm³

Step-by-step explanation:

180 - 82 = 98 Degrees

(3x + 16) + (6x + 1) = 9x + 17

9x + 17 = 98

98 - 17 = 81

81 / 9 = 9

x = 9

6(9) + 1 = 55 Degrees

3(9) + 16 = 43 Degrees

Step-by-step explanation:

A rectangular garden is 5m longer
than it is wide.
The area of the garden is 600m2
Calculate the width and length of the garden.​

Answers

Answer:

The width of the garden is 22.12 m and its length is 27.12 m

Step-by-step explanation:

Equations

Let x = width of the garden

The length is 5 m longer than the wide, thus:

x + 5 = length of the garden

The area of the rectangular garden is

A=x(x+5)=600

Operating:

[tex]x^2+5x-600=0[/tex]

Solving with the quadratic formula:

[tex]\displaystyle x=\frac{-b\pm \sqrt{b^2-4ac}}{2a}[/tex]

Where a=1 b=5 c=-600:

[tex]\displaystyle x=\frac{-5\pm \sqrt{5^2-4(1)(-600)}}{2(1)}[/tex]

Operating:

[tex]\displaystyle x=\frac{-5\pm \sqrt{25+2400}}{2}[/tex]

[tex]\displaystyle x=\frac{-5\pm \sqrt{2425}}{2}[/tex]

There are two solutions:

x = 22.12

x = -27.12

The negative solution is not valid because x is the width of the garden, thus

x = 22.12 m

And

y = 22.12 + 5 = 27.12 m

The width of the garden is 22.12 m and its length is 27.12 m

Read the story "Memories Of A Memory" and answer the questions.Have you ever witnessed something amazing, shocking or surprising and found when describing the event that your story seems to change the more you tell it? Have you ever experienced a time when you couldn't really describe something you saw in a way that others could understand? If so, you may understand why some experts think eyewitness testimony is unreliable as evidence in scientific inquiries and trials. New insights into human memory suggest human memories are really a mixture of many non-factual things.First, memory is vague. Imagine your room at home or a classroom you see every day. Most likely, you could describe the room very generally. You could name the color of the walls, the floors, the decorations. But the image you describe will never be as specific or detailed as if you were looking at the actual room. Memory tends to save a blurry image of what we have seen rather than specific details. So when a witness tries to identify someone, her brain may recall that the person was tall, but not be able to say how tall when faced with several tall people. There are lots of different kinds of "tall."Second, memory uses general knowledge to fill in gaps. Our brains reconstruct events and scenes when we remember something. To do this, our brains use other memories and other stories when there are gaps. For example, one day at a library you go to quite frequently, you witness an argument between a library patron and one of the librarians. Later, when telling a friend about the event, your brain may remember a familiar librarian behind the desk rather than the actual participant simply because it is recreating a familiar scene. In effect, your brain is combining memories to help you tell the story.Third, your memory changes over time. It also changes the more you retell the story. Documented cases have shown eyewitnesses adding detail to testimony that could not have been known at the time of the event. Research has also shown that the more a witness's account is told, the less accurate it is. You may have noticed this yourself. The next time you are retelling a story, notice what you add, or what your brain wants to add, to the account. You may also notice that you drop certain details from previous tellings of the story.With individual memories all jumbled up with each other, it is hard to believe we ever know anything to be true. Did you really break your mother's favorite vase when you were three? Was that really your father throwing rocks into the river with you when you were seven? The human brain may be quite remarkable indeed. When it comes to memory, however, we may want to start carrying video cameras if we want to record the true picture.1.
