what is the area of the shaded part of the figure (in square units)?

Answer:

B

Step-by-step explanation:

The SA of a cone is A=pi*r^2+pi*r*s

So instead of pi*5^2, it should be pi*3*5 (5 is the length of the slant).

Answer:

288

Step-by-step explanation:

12*6*2 = 144

12-4=8

8*6*2 = 96

8-4=4

4*6*2= 48

48+96+144 = 288

Answer:

63 is 60% of 105.

Step-by-step explanation:

Divide 63 by 3 to get 21.  Now that you get 1/3 of that number, it would also mean that 21 is 20% of the full number.  Multiply 21 by 5 to get the full number which is 105.

Answer:

105

Step-by-step explanation:

63 = 60% x ?

60/100 x ? = 63

100/60 x 60/100 = 1 (you do this to cancel it out)

60/100 x 63 = 105

Answer:

Its 36

Step-by-step explanation:

because AB=7x9 = 63

so BC= (4x9)36

The correct answer would be option (A) because the family would be dependent.

A dependent Event is defined as if the outcome of one event has bearing on the outcome of the other, the two events are said to be dependent events. Or, we may say that an event is considered dependent if it does affect the probability of another event. Probability-dependent is dependent on occurrence.

The probability is defined as the possibility of an event being equal to the ratio of the number of favorable outcomes and the total number of outcomes.

According to option (A),

The first child in a family is a boy. The second child is also a boy.

A boy is the family's youngest. Another boy is the second child.

Here the family would be the dependent.

Hence, the correct answer would be an option (A).

Answer:

[tex]5,890,000=5.89\times 10^6[/tex]

Step-by-step explanation:

The given number is 5,890,000.

We need to express in scientific notation.

A number can be written in scientific notation as follows :

[tex]N=a\times 10^b[/tex]

Where

a is a real number and b is an integer

[tex]5,890,000=5.89\times 10^6[/tex]

Hence, a = 5.89 and b = 6.

The point would be (-2,1). x = -2, y = 1. I hope this helps, have a good day!

Answer is the second bullet

Step-by-step explanation:

Answer:

141 km

Step-by-step explanation:

Given data

Mean distance= 153km

Let Tina dirve=x km

Ben= x+ 24

Number of participants= 2

Hence,

Mean= total distance/number of participants

153= x+24+x/2

cross multiply

153*2= x+24+x

306 =2x+24

306-24= 2x

282=2x

Divide both sides by 2

x= 282/2

x= 141km

Hence Tina drove 141 km

Answer:

72 degrees

Step-by-step explanation:

Complementary angles add up to 90 degrees.  Thus, the complement of 18 degrees is (90 - 18) degrees, or 72 degrees.

Step-by-step explanation:

Just multiply the area by the height.

Like a square with the area of L x W the volume is L x W x H because you've added an additional dimension

Answer:

y doesn't have multiple awnser, y = 47.5

Step-by-step explanation:

(y + 7) + (3y - 17) = 180

=> 4y = 190

=> y = 47.5

Answer:

47.5

Step-by-step explanation:

If r is parallel to s, then by the Alternate Exterior Angles Theorem:

x+56 = 3y-17. Additionally, (x+56)° is supplementary to (y+7)° because they make up a line.

So: 180 = x+56 + y+7 or

180-y-7 = x+56

Substitute into x+56 = 3y-17 so that 180-y-7 = 3y-17.

Solve for y to get y = 47.5

____ = _____ = 1/2, A is your answer

5 - 3          2

Answer:

1/2

Step-by-step explanation:

Based on the graph, we can see that the two points plotted are (3,3) and (5,4) We also know that slope is calculated through this formula:

[tex]\frac{y1-y2}{x1-x2}[/tex]

Therefore, let's substitute the x and y of the points plotted into that formula:

[tex]\frac{4-3}{5-3}[/tex]

Simplify:

[tex]\frac{1}{2}[/tex]

Therefore, the slope is 1/2

Answer:

5/8 (= 0.625)

Step-by-step explanation:

tan A = sin A / cos A

we have here a triangle that is much bigger than to fit into our snuggly around a norm circle (radius = 1).

so, we could either see it embedded in a circle with a radius of the square root of 89, or surrounding a circle with the radius of 8.

in the first case

[tex]5 = \sin(a) \times \sqrt{89} [/tex]

[tex]8 = \cos(b) \times \sqrt{89} [/tex]

in the second case 5 is already tan A but stretched by the radius 8.

so,

[tex]5 = \tan(a) \times 8[/tex]

so, in both cases the answer is 5/8.
