Answer:

b. False

Step-by-step explanation:

False because supplementary angle means that either of two angles sum is 180°

If one supplementary angle measure is 51°, then the other angle measure should be 129°

Answer: The length of ¯¯¯¯NP is 10 inches.

Step-by-step explanation:

To find the length of ¯¯¯¯NP, we need to use the Pythagorean theorem, which states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.

In this case, triangle NOP is a right triangle because angle N is a right angle (shown by the small square in the corner). Therefore, we can use the Pythagorean theorem to find the length of ¯¯¯¯NP.

Let's label the sides of triangle NOP. The side opposite angle N is ¯¯¯¯OP, which has a length of 8 inches. The side opposite angle P is ¯¯¯¯NO, which has a length of 6 inches. Finally, the hypotenuse, which we want to find, is ¯¯¯¯NP.

Using the Pythagorean theorem, we get:

¯¯¯¯NP2=¯¯¯¯OP2+¯¯¯¯NO2

¯¯¯¯NP2=82+62

¯¯¯¯NP2=64+36

¯¯¯¯NP2=100

Therefore,

¯¯¯¯NP=sqrt(100)=10

Answer:

D is the right choice and no you cannot fit the pizza inside the box.

Step-by-step explanation:

D is the answer because to turn 2/3 into a decimal you would divide 2 by 3 and the answer you would get would be 0.66666666666...You would then add 12 to the answer and get 12.6666... Once you get this answer you would round it to the hundredths to get 12.67 but since that is not an option you could use D, 12.66 inches.

Answer:

I believe the answer is D.

Answer: The circumference of the cylinder's base is 6 units.

Radius = 1/2(6/pi)

Volume = r2pi*h

h = (27/2) / r2pi

sin(∠BAD) = h / 6

Answer:

Step-by-step explanation:Situation A: The hang glider descended 33.57 feet and again ascended 14.98. So 33.57 - 14.98 = 18.58. So now the hang glider is at 18.58 feet

Situation B: Initially they gained 7 2/5 yards and then lost 3/5 yards.

7 2/5 yards can be written as 37/5. As they lost 3/5 yards, 37/5 - 3/5 = 34/5. So the remaining yards are 34/5 yards.

Situation C: Hiker walked 3 1/6 miles and then 2 1/2 miles. So the total distance is 3 1/6 + 2 1/2 = 5 4/6 miles.

Situation D: Total amount earned is $23.66 + $15.84 = $39.5.

4. x=cows and y= sheep+goats

Answer/x= (y+140)/2

Answer:

X is equal to 5

Step-by-step explanation:

If you find the area of the 6 by 10 rectangle part of the shape first,

it is 60.

To find X we simply do 75-60, which leaves us with 15.

Since 15/3 is 5, then X equals 5

Answer:

x=5

Step-by-step explanation:

6×10=60

75-60=15

15÷3=5

x=5

Answer:

D) 27

Step-by-step explanation:

It's a rectangle so the opposite sides are congruent to each other.

Long Side:

6x + 6 = 42

subtract 6 from both sides:

6x = 36

divide both sides by 6:

x = 6

Short Side:

5y + 5 = 30

subtract 5 from both sides:

5y = 25

divide both sides by 5:

y = 5

The Equation:

2x + 3y

substitute in the values:

2(6) + 3(5)

do the multiplication:

12 + 15

add the values together:

Answer:110

Step-by-step explanation: just divide by 2 to find out half.

110 is half of 220.

Here, we have,

To find half of a number, you divide it by 2.

In this case, to find half of 220, you divide 220 by 2:

220 ÷ 2 = 110

Therefore, half of 220 is 110.

When we divide 220 by 2,

we are splitting it into two equal parts, with each part being 110.

so, we get,

110 is half of 220.

Answer:

Sure, I'll explain the cosine rule and sine rule in simple terms:

The cosine rule (also known as the law of cosines) is used to find the length of a side or the measure of an angle in a triangle given the lengths of the other sides and the angle between those sides. It states that c^2 = a^2 + b^2 - 2ab cos(C), where c is the length of the side opposite angle C, and a and b are the lengths of the other two sides.

Here's an example of how to use the cosine

Suppose we have a triangle with sides a=6, b=8, and an angle between them c=45 degrees. We want to find the length of the remaining side of the triangle, side a.

Using the cosine rule:

a^2 = b^2 + c^2 - 2bc * cosA

where A is the angle opposite side a, we can plug in our values and solve for a:

a^2 = 8^2 + 6^2 - 2(8)(6) * cos(45)

a^2 = 64 + 36 - 96 * 0.707

a^2 = 10.56

a = sqrt(10.56)

a = 3.25 (rounded to two decimal places)

Therefore, the length of side a is approximately 3.25 units.
