AB is a chord of a circle of radius 5cm the distance of AB from the centre is 3cm then AB is?​

Answers

Answer 1

Answer:

8 cm

Step-by-step explanation:

We first want to draw a diagram with the given information.

I am unsure if the image shows below, or if it is an attachment.

We then see we have a right triangle. What is a theorem that is commonly associated with right triangles?

So we use the pythagorean theorem to find the missing leg of the triangle has a length of 4 cm. But how does this help us? Well, when finding the distance from the center of a circle to a chord, we always find the line that is perpendicular to the chord and divides it in half (and passes through the center), and find the length.

So, the leg of length 4 we just found? That's half of our answer.

Since 4 × 2 = 8, we know that the length of AB is 8 cm.

My teacher wants me to write the angles of a circle what are they?

Answers

Like the whole circle is 360°
If you mean the angles in a circle then I would recommend looking at the unit circle

Answer:

Well the only answer to this question that I can think of is 360 that's because all of the angles in a circle are equal to 360.

A train leaves Boston at 10:20 AM and arrives in Stamford at 1:00 PM. Find the distance between the stations if the average speed of the train is 60 mph

Answers

Answer: 160 miles

Step-by-step explanation: From 10:20 to 12:20 is 2 hours which is 120 minutes and it is 60mph so it is 1 mile per minute. 12:20 to 1:00 is 40 minutes so you add 40 to 120 which makes it 160. So the answer is 160 miles

The Answer would be : 160 miles

There are 2,100 bacteria in a circular petri dish. The dish has a radius of 40 millimeters. What is the approximate population density? (Use 3. 14 for π) Area of a circle = πr2 0. 02 bacteria per square millimeter 0. 42 bacteria per square millimeter 2. 39 bacteria per square millimeter 52. 5 bacteria per square millimeter.

Answers

Answer:

B) 0.42

Step-by-step explanation:

population density=number of people/square units

we plug in 2,100 for the first one but we don't know the second one for that we need the area which is A=π[tex]r^{2}[/tex] so the radius is 40 millimeters so [tex]40^{2}[/tex] =1600 1600*π=5024

2,100/5024=0.417 round it up and it is 0.42

so B) 0.42 is the answer

The rid Daaé’s Grave is 6min long. Dave thinks that the first ¼ of the ride was the most fun. How many minutes were the most fun for Dave. Solve Algebraically.


100 points first correct answer gets Brainlyest.

Answers

Answer:

Dave had most fun for 1.5 minutes.

explanation:

Let the "fun time" be f

total time * portion of time fun  = fun time

[tex]\sf t * p = f[/tex]

[tex]\sf 6 \ * \frac{1}{4} = f[/tex]

[tex]\sf \frac{6}{4} = f[/tex]

[tex]\sf f = 1.5 \ minutes[/tex]

Question was for how many minutes, Dave had fun, so he had fun for 1.5 minutes

Let that half be x

So

[tex]\\ \rm\Rrightarrow x(4)=6min[/tex]

[tex]\\ \rm\Rrightarrow x=6/4[/tex]

[tex]\\ \rm\Rrightarrow x=1.5min[/tex]

(-3/8) times 1 times (-9/10) times -8/3

Answers

Step-by-step explanation:

-3/8 × 1 × -9/10 × -8/3

we know

- × - = +

+ × - = -

therefore, since we have 3 negative factors we get a negative result.

we can ignore the completely neutral multiplication by 1.

-3/8 × -9/10 × -8/3 = -(3×9×8)/(8×10×3) = -9/10

If a basketball player made 72 out of 85 free throws attempts how many could she make in 200 attempts

Answers

Answer:

169

Step-by-step explanation:

Use a proportion:

72/85=x/200

Solve for x

(72)(200)=85x

x=(72)(200)/85

x=169.41≈ 169

She can make 169 of 200 free throws.

The ratio of the sides of a triangle is 2:4:7. If the perimeter of the triangle is 182 cm what is the longest side?

Answers

Answer:

98 cm

Step-by-step explanation:

sum the parts of the ratio , 2 + 4 + 7 = 13 parts

divide perimeter by 13 to find the value of one part of the ratio.

182 ÷ 13 = 14 cm ← value of 1 part of the ratio , then

2 parts = 2 × 14 = 28 cm

4 parts = 4 × 14 = 56 cm

7 parts = 7 × 14 = 98 cm

the longest side is 98 cm

Rewriting the whole as an Equivalent Fraction

4.1   Adding a whole to a fraction

Rewrite the whole as a fraction using  (x-8)  as the denominator :

         -2     -2 • (x - 8)

   -2 =  ——  =  ————————————

         1        (x - 8)  

Equivalent fraction : The fraction thus generated looks different but has the same value as the whole

Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator

Adding fractions that have a common denominator :

4.2       Adding up the two equivalent fractions

Add the two equivalent fractions which now have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

3x2 + -2 • (x-8)     3x2 - 2x + 16

————————————————  =  —————————————

   1 • (x-8)          1 • (x - 8)

Trying to factor by splitting the middle term

4.3     Factoring  3x2 - 2x + 16

The first term is,  3x2  its coefficient is  3 .

The middle term is,  -2x  its coefficient is  -2 .

The last term, "the constant", is  +16

Step-1 : Multiply the coefficient of the first term by the constant   3 • 16 = 48

Step-2 : Find two factors of  48  whose sum equals the coefficient of the middle term, which is   -2 .

     -48    +    -1    =    -49

     -24    +    -2    =    -26

     -16    +    -3    =    -19

     -12    +    -4    =    -16

     -8    +    -6    =    -14

     -6    +    -8    =    -14

what is the volume of a right rectangular prism with a base that measures 4 in by 6 in. and a height of 7 in? a) 17 in.3. b) 51 in.3. c) 84 in.3. d) 168 in.3.

Answers

Answer:

d) 168 in.³

Step-by-step explanation:

volume = length × width × height

volume = 6 in. × 4 in. × 7 in.

volume = 168 in.³

Answer: d) 168 in³

Step-by-step explanation:

        The volume of a right rectangular prism can be found by multiplying the base (the length times the width) by the height. Since we are given all the values needed, we can multiply them all together and find our answer.

                 V = length * width * height

                 V = 4 in * 6 in * 7 in

                 V = 168 in³

  This gives us an answer of "d) 168 in³"
