The circumference of a circle is 8.88cm. Find the length of the diameter. Give your answer rounded to 2 DP.

Answer:

Some ways on how to solve the questions:

Use formulas as given by your teacher.

Application of the Pythagorean Theorem would be useful for 5 and 6.

For 7-10 use a formula as given by your teacher (just basic operations like plugging in the formula for those questions)

For 11 and 12 draw it out.

Answer:

9/15=3/5

so 3/5 is equivalent fraction of the 9/15

Answer:

I'm going to say no

Step-by-step explanation:

Because y in the pair y is zero not 9.

the angle that is vertical to ABI is EBH

Answer:

10 feet

Step-by-step explanation: 2+2=4  3+3=6   4+6=10

Answer:

5/6 is about a 84%, and 84% of 15 questions is 12.6. so the teacher just made the grading simplified

Step-by-step explanation:

Answer:

(x, y) right-arrow (x minus 5, y minus 3)

Step-by-step explanation:

we know that

The translation of the pre-image STU to the image ST'U' is  3 units down and 5 units to the left

That means

3 units down -----> y-3

5 units to the left -----> x-5

therefore

The rule of the translation is

(x,y) -----> (x-5,y-3)

Answer:

Step-by-step explanation:

-a + 6b = -3 + 6 * (-6) = -3 - 36 = -39

Substitute the values in:

-a + 6b

-(3) + 6(-6)

-3 + (-36)

= -39

Answer:

1.51*10^5 cm^3

Step-by-step explanation:

the formula for the volume of a sphere is (4/3)pi(radius)^3

I can't really tell if the 33 cm is for the radius or the diameter, but it looks like the radius, so

(4/3)*(33)^3*pi

simplify

Im assuming you can use a calculator because it's too hard to do without because it's a huge number

Answer:

a) BOC = 80⁰

b) COD = 60⁰

Step-by-step explanation:

..................

Answer:

BOC is 80 and COD is 60

Step-by-step explanation:

If DOF is 120 you subtract 40 from it because of of AOB then COD is the remaining of 180

Answer:

If Y represents the number of green balls then it can have values from 0- 5

that is it can have all the value  0,1,2,3,4 and 5.

The probability of getting both balss green without replacement is 0.27778

Step-by-step explanation:

If the balls are not replaced then this is the dependent event .

The probability of getting the first ball is given be = 5/9

where 5 is the number of green balls and 9 is the total number of balls.

The probability of getting the second ball green given that first is also green is  = 5/9* 4/8= 20/72= 0.2778

If Y represents the number of green balls then it can have values from 0- 5

that is it can have all the value  0,1,2,3,4 and 5.

0 means there can be no green balls or white balls.

1 means there can be one green ball.

2 means there can be 2 green balls and so on.

In this exercise we have to use the knowledge of probability to calculate the chance of an event to occur, so you have to:

the chance of the event is 0.2778%

So organizing the information given in the statement is:

So with this information we can write that:

[tex]5/9* 4/8= 20/72= 0.2778[/tex]

Answer:

The airplane ascends [tex]81\,\frac{3}{4}[/tex] meters in one second.

Step-by-step explanation:

Given that the airplane ascends [tex]54\,\frac{1}{2}[/tex] ([tex]\frac{109}{2}[/tex]) meters in [tex]\frac{2}{3}[/tex] seconds, we calculate the ascent rate of the airplane by simple rule of three:

[tex]x = \frac{\frac{109}{2}\,m }{\frac{2}{3}\,s } \times 1\,s[/tex]

[tex]x = \frac{327}{4}\,m[/tex]

[tex]x = 81\,\frac{3}{4}\,m[/tex]

The airplane ascends [tex]81\,\frac{3}{4}[/tex] meters in one second.

Answer:

The sprinkler will cover an area of [tex]50m^2[/tex]

Step-by-step explanation:

Given

[tex]Area = 240m^2[/tex]

[tex]\theta = 75^{\circ}[/tex]

Required

Determine the amount of area it can cover

The amount of area is calculated by calculating the area of a sector using:

[tex]Sector\ Area =\frac{\theta}{360^{\circ}} * \pi r^2[/tex]

Where:

[tex]Area = \pi r^2 = 240m^2[/tex]

So, we have:

[tex]Sector\ Area =\frac{\theta}{360^{\circ}} * 240m^2[/tex]

Substitute 75 for [tex]\theta[/tex]

[tex]Sector\ Area =\frac{75^{\circ}}{360^{\circ}} * 240m^2[/tex]

[tex]Sector\ Area =\frac{75^{\circ}* 240m^2}{360^{\circ}}[/tex]

[tex]Sector\ Area =\frac{75* 240m^2}{360}[/tex]

[tex]Sector\ Area =\frac{18000m^2}{360}[/tex]

[tex]Sector\ Area =\frac{18000}{360} m^2[/tex]

[tex]Sector\ Area =50m^2[/tex]

Hence, the sprinkler will cover an area of [tex]50m^2[/tex]

Answer:

0.9 liters.

Step-by-step explanation:

The difference between 20% of 3 and 50% of 3 is 30%. 30% of 3 liters is 0.9 liters so this is what you add to can A.

Answer: She sold 6.6kg of pears in the market.

Step-by-step explanation:

 Weight of apples and pears at the farmer's market.=8.8 kilograms

Weight of apples = 1/4

which is = 1/4 x 8.8kg = 2.2 kg

Weight of Pears =Weight of apples and pears - Weight of apples

= 8.8kg- 2.2kg

= 6.6kg

Answer:

The slope is 3.75 OR 3 3/4.

Step-by-step explanation:

So the formula for slope I am using NOW, is based on the variables I named my dimensions. WARNING: NOT SLOPE FORMULA YOU MIGHT BE USING

y = 95 - 80

x = 10 - 6

Slope Formula: y/x

Substituted Slope Formula: (95 - 80)/(10 - 6)

Simplified Substituted Slope Formula: 15/4 OR 3.75

Answer:

26. ∠ABC=44

27. ∠ABC=86

28. ∠ABC=116

Step-by-step explanation:

Since BD bisects ∠ABC in each diagram, ∠ABD=∠DBC.

26.

∠ABD=∠DBC

5x+2=7x-6

2x=8

x=4

∠ABC=∠ABD+∠DBC

=5(4)+2+7(4)-6

=20+2+28-6

=44

27.

∠ABD=∠DBC

11x-12=8x+3

3x=15

x=5

∠ABC=∠ABD+∠DBC

=11(5)-12+8(5)+3

=55-12+40+3

=86

28.

∠ABD=∠DBC

9x-23=5x+13

4x=36

x=9

∠ABC=∠ABD+∠DBC

=9(9)-23+5(9)+13

=81-23+45+13

=116

Answer:

50 times

Step-by-step explanation:

Red = 5 ; blue = 6 ; green = 3 ; black = 4 ; yellow = 2

Total number of marbles :

(5 + 6 + 3 + 4 + 2) = 20

Probability of drawing a yellow or green marble :

P(yellow) + p(green)

(2 / 20) + (3 / 20)

5 / 20

Hence, Number of times from 200 draws :

(5 / 20) * 200

= 50

Answer: 4.1 inches

Step-by-step explanation:

From the question, we are informed that New York City is approximately 205 miles from Washington, D.C.

The distance that these cities will appear on a map with the scale 1 in: 50 miles will be represented by x.

Therefore, x:205 = 1:50

Cross multiply

x/205 = 1/50

50x = 205

x = 205/50

x = 4.1 inches

The answer is 4.1 inches
