Answer:

x = 76

Step-by-step explanation:

The inscribed angle x is half the measure of its intercepted arc.

x = [tex]\frac{1}{2}[/tex] × (102 + 50) = 0.5 × 152 = 76

Answer: 16 + z

Step-by-step explanation:

It's just 9 + 7 plus 2z - z, subtract the 2z by the z, you get 1z, which is better off being written as just z.

Answer:

4x^2 B

-4x^2 A

1/4x^2 D

-1/4x^2 C

Step-by-step explanation:

1. Look at the concavity

    up or down = negative or positive.

2. number before the x value

if N < 1, it will be wider.     if N > 1, it will be thinner.

3. the two most right graphs would be -1/4x^2 and 1/4x^2

the one that is concave down is the - and the concave up is +

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:

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:

8400 in^3

Step-by-step explanation:

leg1 = √37^2 - 35^2 = √1369 - 1225 = √144 = 12 in

Base area = (12 x 35)/2 = 210 in^2

Volume = 210 x 40 = 8400 in^3

Answer:

8400

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:

48 yards

Step-by-step explanation:

To calculate the perimeter you have to add the outline of the triangle together.

16 + 16 + 16 = 48

You can also do 16 × 3 = 48

So, your answer is 48 yards.

Have a great day! :)

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

Step-by-step explanation:

supplementary angles : angles that add up to 180 degrees

complementary angles: angles that add up to 90 degrees

adjacent angles: angles next to each other

vertical angles: angles directly across from each other

alternate interior angles: angles inside of 2 lines In opposite side of transversal.

alternate exterior angles: angles outside of 2 lines in opposite side of transversal

corresponding angles: angles on same side of transversal and same relative position to lines crossed by transversal.

please mark me brainliest, thanks

Answer:

I think the second answer

Step-by-step explanation:

I'm late but it's the second answer!

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:

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.
