Answer: Choice D

Your book may use the template [tex](x-h)^2 + (y-k)^2 = r^2[/tex], but it's the same idea. The center here is (h,k) and radius is r.

Answer:

y = -1x -5

Step-by-step explanation:

y2 - y1 / x2 - x1

-9 - (-5) / 4 - 0

-4 / 4

-1

y = -1x + b

-5 = -1(0) + b

-5 = 0 + b

b = -5

y = -1x -5

Step-by-step explanation:

5b²+39b=8

<=> 5b²+39b-8=0

(5b-1)(b+8)=0

b = ¹/5 or b = -8

b=-8 and b=1/5.

Answer:

Solution given:

5b²+39b=8

5b²+39b-8=0

try to do middle term factorization.

it needs 40 while multiplication and 39 when subtraction.

it is 40-1 and 40*1

now

doing middle term factorization

5b²+(40-1)b-8=0

5b²+40-b-8=0

take common from each 2 term

5b(b+8)-1(b+8)=0

again take common and keep remaining in another brackets

(b+8)(5b-1)=0

either

b=-8

or

b=1/5

Answer:

its the 1st answer choice/A

Answer:

82.8 in²

Step-by-step explanation:

The surface area a triangular based pyramid :

Base area + 1/2(perimeter * slant height)

Base = 8 inches ; Slant height = 4.6 inches ; altitude of base measure = 6.9 inches

Base area of triangle :

1/2 * base * height

1/2 * 8 * 6.9

4 * 6.9

Base area = 27.6 in²

The perimeter, P = sum of sides ; (s1 + s2 + s3

P = 8 + 8 + 8 = 24 in

Hence,

Surface area = 27.6 in² + 1/2(24*4.6)

Surface area = 27.6 in² + (12 * 4.6) in²

Surface area = (27.6 + 55.2)

Surface area = 82.8 in²

Answer:

9a) 6 1/5

b) 6 4/7

c) 1 1/0

d) 4 1/8

e) 1 1/3

f) 3 1/6

10a) 15 years old

b) 14 1/6 years old

11) 8/3 = 2 2/3

7/5 = 1 2/5

2 2/3 + 1 2/5 = 4 1/15

12a) They ate 3 11/12 pizzas

b) They ate 1 1/3 more cheese pizzas than veg

Answer:

Q4) 23

Q5) 18

Q6) 15

Step-by-step explanation:

Q6) In the given Stem and Leaf Plot, we have, the average weights as follows;

0.1, 0.1, 0.1, 0.2, 0.2, 0.3, 0.4, 0.4, 0.5, 1, 1, 1.2, 1.3, 1.7, 2.2

By counting the number of data given above, n = 15

Q5) The given data in the stem and leaf diagram are;

7, 9, 14, 15, 16, 18, 18, 21, 23, 30

The median of the 10 data points is the (10 + 1)/2 or the 5.5th data point

The fifth data point = 18

The sixth dat point = 18,

Therefore, the median, which is the 5.5th data point = 18 + (18 - 18)/2 = 18

The median = 18

Q4) The given data points are;

7, 9, 14, 15, 16, 18, 18, 21, 23, 30

The range = The largest data point value - The least data point value

Therefore;

The range = 30 - 7 = 23

The range = 23

Answer:

The correct answer is B

Answer:

sin = 2/3

cos = sqrt5/3

tan = 2/sqrt5

Answer:

17/52 (Answer B)

Step-by-step explanation:

There are four queens and 13 hearts.  The probability of drawing a Queen is thus 4/52 (= 1/13); that of drawing a Heart is 13/52 (= 1/4).  

The probability of drawing either is 1/13 + 1/4, or 4/52 + 13/52, or 17/52 (Answer B)

Answer:

[tex]m\angle ADB=58^{\circ}[/tex]

Step-by-step explanation:

For an angle with a point on the circle, the measure of that angle is equal to half the measure of the arc it forms. Since angle ADB forms an arc AB that measures [tex]116^{\circ}[/tex], the measure of angle ADB equals [tex]\frac{116}{2}=\boxed{58^{\circ}}[/tex]

Step-by-step explanation:

ADB=116/2(inscribed angle is half of it's arc)

Answer:

3^3 = 27

27 * 3.14 = 84.78

84.78 * 4/3 = 113.04 is your answer.

Formula of volume of sphere is:

4/3 x π(3.14 or 22/7 whatever they tell you to use for pi) x r^3(your radius being cubed)

You get your radius by finding out what is half of your diameter or your given radius.

Answer:

41 ft

Step-by-step explanation:

Since that's the height the Robin flew to.

Answer:

its either 41 feet or 50 feet or neither cause im dum.b

Step-by-step explanation:

41 feet explanation = the bird was on the ground and was 9 feet away from the tree so the bird moved 9 feet ON THE GROUND and then flew up 41 feet

50 feet explanation = the bird was on a branch 9 feet up from the tree base and flew the rest of the 41 feet

Answer: [tex]\dfrac{1}{3}[/tex]

Step-by-step explanation:

Given

There are 9 chips numbered 1 to 9 placed in a box

Margie selected one chip from the box

If the chip is multiple of 3 then the chip can be 3, 6, or 9

So, the probability associated with this is

[tex]\Rightarrow P=\dfrac{\text{favorable}}{\text{Total}}\\\\\Rightarrow P=\dfrac{3}{9}\\\\\Rightarrow P=\dfrac{1}{3}[/tex]

Answer:[tex]376.80\ mm^3[/tex]

Step-by-step explanation:

Given

The height of the cone is [tex]h=10\ mm[/tex]

The radius of the cone is [tex]r=6\ mm[/tex]

Volume of cone is given by

[tex]V=\dfrac{1}{3}\pi r^2h[/tex]

Insert the values

[tex]\Rightarrow V=\dfrac{1}{3}\times 3.14\times 6^2\times 10\\\\\Rightarrow V=376.80\ mm^3[/tex]

Thus, the volume of the cone is [tex]376.80\ mm^3[/tex]
