Find the area of semi circle , π = 3, d = 12

Answers

Answer:

120cm *squared*

Step-by-step explanation:

A = π r² to find a circle

half of diameter is radius so 12/2 = 6

3 x 6 (squared) = 108

we found the half circle then add 12

so we make a semi circle

108 + 12= 120

answer 120 cm *squared*

what is the exterior angle?

Answers

The value of x° is 22° and exterior angle is 25.

Step-by-step explanation:

l can prove like this,

Here,2x°+(103-x)°=(6x-7)°...Being exterior angle

or,2x°+103°-x°=6x°-7°

or,x°+103°=6x°-7°

or,103°+7°=6x°-7°

or,5x°=110°

or,x°=110°÷5=22°

Now,

x°=22°

(6x-7)°=(6×22-7)°=125°

Anthropologists approximate the height of a primate by the size of its humerus (the bone from the elbow to the shoulder) using the equation

H = 1.2L + 27.8,

where L is the length of the humerus and H is the height, in inches, of the primate.


An anthropologist estimates the height of a primate to be 60 in. What is the approximate length of the humerus of this primate? Round to the nearest tenth of an inch.

Answers

Answer:

26.83

Step-by-step explanation:

H=1.2L + 27.8

60=1.2x+27.8

minus 27.8 from both sides

32.2=1.2x

divide both sides by 1.2

x=26.83

X=40
Y=70.
Z=70. They must add up to 180

Answer:

A. 40°

Step-by-step explanation:

As we can see it is an isosceles triangle because two sides are equal. so Base angles of an isosceles triangle are equal. Then Now.,

70° + 70° + <X = 180° {Being sum of angles of triangle }

140° + < X = 180°

< X = 180° - 140°

< X = 40°

Joe wants to buy a $180 number that's on is on sale the snowboard is 30% off what is the sale price of the snowboard (show work)

Answers

Answer:

Step-by-step explanation:

Assuming that the Skateboard is $180, and you are asking for the price when it is 30% off.

180 * .70 = $126

Another way of solving the question is finding 10 % of 180, which is 18. And you are looking for 30% less, so 18 * 3 = 54, which is 30% of 180.

180 - 54 = 126

54 is the correct answer

Complementary angles, adjacent angles

Step-by-step explanation:

Which relationships describe angles 1 and 2?

Options: Complementary angles, vertical angles, supplementary angles, adjacent angles

Angles 1 and 2 are opposite to the 90° angle. So, the angles' relationship to that angles is a vertical angle, meaning that the two add up to 90°.

Complementary angles add up to 90°, so this option is correct.

Vertical angles are the pairs of opposite angles formed by two intersecting lines. Because the two angles do not follow this definition, this option is incorrect.

Supplementary angles add up to 180°. However, we know that the two add up to 90°, so this option is incorrect.

Adjacent angles are angles that are next to each other, so this option is correct.

3(4x + 2) +2(x-1) please help me with this equation

Answers

Answer:

14x + 4

Step-by-step explanation:

3(4x+2) + 2(x-1)

Distribute by multiplying into the bracket

=12x + 6 + 2x - 2

Group like terms by adding and subtracting

= 14x + 4

Answer:

1) Multiply and expand the brackets:

12x + 6 + 2x - 2

2) Combine like terms (combine terms that have an x together, and those that don't together.)

14x + 4

If the question wanted you to simplify the expression, then 14x + 4 is your answer. However, to solve for x, you could equate the expression to 0, but I'm not too sure of this part.

14x + 4 = 0

14x = - 4

x = - 4/14

x = - 2/7
