============================================================

Explanation:

As the diagram shows, we have a triangular face with a base of b = 18 and height of h = 13. The area of this triangular face is:

A = 0.5*b*h

A = 0.5*18*13

A = 117 square cm or cm^2

This represents the area of one face, but there are 4 identical copies of this triangular face assuming this tetrahedron is a regular polyhedron. So we have a total surface area of 4*117 = 468 cm^2 which points us to choice B

This is the amount of paint you'll need to cover the outer surface of the pyramid, or you can think of it as the amount of wrapping paper needed. This assumes there are no gaps or overlaps.

Answer:

equilateral

Step-by-step explanation:

A shape is equilateral if all the sides are the same length. In geometry class, people learn about many shapes, such as triangles and squares. A square is equilateral, because all of its sides are the same length. ... The word equal should help you remember what equilateral means.

Answer:

An isosceles triangle has 2 sides of equal length . The dashes on the lines show they are equal in length. The angles at the base of the equal sides are equal.An equailateral triangle has 3 sides of equal length.

Answer:

8/pi or approximately 2.55 ft

Step-by-step explanation:

The formula for the circumference is

C = 2 * pi *r

16 = 2 * pi *r

Divide each side by 2 pi

16 / ( 2 pi) = 2 * pi * r/ ( 2 pi)

8 / pi = r

Using 3.14 for pi

8 / 3.14 = r

2.54777 = r

2.55 =r

Answer:

297

Step-by-step explanation:

Since we have to make 9 as the whole, and 33 is the denominator to make 9, we need to multiply 9*33=297.

This makes no sense if you hear it. But trust me it is the right answer i think.

Answer:

z = 30; obtuse isosceles triangle

Step-by-step explanation:

4z + z + 30 = 180

5z + 30 = 180

5z (+ 30 - 30) = 180 - 30

5z = 150

5z/5 = 150/5

z = 30

Since z = 30, and 30 = 30, two angles are congruent to each other and there is only one obtuse angle. Therefore, this is an obtuse isosceles triangle.

Answer:

30, obtuse isosceles

Step-by-step explanation:

Tow sides are the same making it an isosceles triangle. This requires two of the same sides and two of the same angles. This means that z is the sameas 30 degrees.

Answer:

145 degrees

Step-by-step explanation:

All angles in a parallelogram always add up to 360 degrees when added together.

And all angles are the same as the angle adjacent to them.

Since we already know that angle DAB is 35, then the adjacent angle BCD, is also 35.

And since we know that all the angles add up to 360, we just gotta do the math.

35 + 35 = 70 and when you subtract 70 from 360 you get 290. Now all you have to do is divide 290 by 2, and you get 145, which is also the same as angle ABC since they are adjacent to each other.

Answer:20

Step-by-step explanation:

Answer:

B. (4x^2 + 3)(x+2)

Answer:

[tex]20 = \frac{Far \ arc - Near \ arc}{2}\\\\20 = \frac{160 - (2m +12)}{2}\\\\40 = 160 - (2m + 12)\\2m + 12 = 160 - 40\\2m = 120 -12\\2m = 108\\m = 54[/tex]

Answer:

m = 54

Step-by-step explanation:

The secant- secant angle 20° is half the difference of the intercepted arcs, that is

[tex]\frac{1}{2}[/tex] (160 - 2m - 12) = 20° ( multiply both sides by 2 to clear the fraction )

- 2m + 148 = 40° ( subtract 148 from both sides )

- 2m = - 108 ( divide both sides by - 2 )

m = 54

Answer:

1. (8,-4), sqrt(12) = 2×sqrt(3)

6. x^2 + (y+5)^2 = 49

7. (x-6)^2 + (y+1)^2 = 144

8. (x+2)^2 + (y-3)^2 = 16

9. (0-0)^2 + (7-3)^2 = r^2

0 + 16 = r^2

Answer:

1) glazed = 48 people

Chocolate = 72 people

Jelly = 24 people

Coconut = 16 people

2)9th grade = 219 students

10th grade = 167 students

11th grade = 147 students

12th grade = 151 students

Step-by-step explanation:

We are solving the examples;

1) We are told that there are 20 students in Kayla's first period class.

No. that preferred glazed donuts = 6

No. that preferred chocolate donuts = 9

No. that preferred jelly donut = 3

Number that preferred coconut donut = 2

Now,there are a total of 160 students in the entire grade. So to find the Number of students in this entire grade that will each prefer the types of donuts listed above, we will solve as;

For glazed donuts; 6/20 × 160 = 48 people

For chocolate donuts; 9/20 × 160 = 72 people

For jelly donut; 3/20 × 160 = 24 people

For coconut donut; 2/20 × 160 = 16 people

2) Total number of students is;

9th grade = 300 students

10th grade = 275 students

11th grade = 250 students

12th grade = 280 students

73% of 9th grade prefer valorant. Thus;

73% × 300 ≈ 219 students

61% of 10th grade prefer valorant. Thus;

61% × 275 ≈ 167 students

59% of 11th grade prefer valorant. Thus;

59% × 250 ≈ 147 students

54% of 12th grade prefer valorant. Thus;

54% × 280 ≈ 151 students

Answer:

No

Step-by-step explanation:

Using the given values, 25 is the largest value, so if this were a right triangle, it would be the hypotenuse.

Using Pythagoras' theorem: For this triangle to be a right triangle, √(21² + 14²) must be equal to 25.

√(21² + 14²) = 25.239 (5sf) ≠ 25

Hence the triangle formed is not right.

Answer:

Con cada depósito se pueden llenar 3,617.28 envases.

Step-by-step explanation:

Dado que el agua de un manantial se conduce hasta unos depósitos cilíndricos que miden 12 m de radio de la base y 20 m de altura, y luego se embotella en bidones de 2.5 litros, para determinar cuántos envases se llenan con cada depósito se debe realizar el siguiente cálculo, sabiendo que el volumen de un cilindro se obtiene multiplicando pi por el radio del cilindro al cuadrado por su altura:

3.14 x (12x12) x 20 = X

3.14 x 144 x 20 = X

452.16 x 20 = X

9,043.2 = X

9,043.2 / 2.5 = X

3,617.28 = X

Por lo tanto, con cada depósito se pueden llenar 3,617.28 envases.

Answer: [tex]0.791\leq p\leq0.909[/tex]

Step-by-step explanation:

The confidence interval for the population proportion is given by:-

[tex]\hat{p}\pm z^*\sqrt{\frac{\hat{p}(1-\hat{p})}{n}}[/tex], where [tex]\hat{p}[/tex]= sample proportion, n =sample space , z* = critical z-value.

As per given, we have

[tex]n = 247[/tex]

[tex]\hat{p}=0.85[/tex]

Critical value for 99.9% confidence = 2.576

The required confidence interval will be:

[tex]0.85-2.576\sqrt{\frac{0.85\times0.15}{247}}\leq p\leq 0.85+2.576\sqrt{\frac{0.85\times0.15}{247}}\\\\\Rightarrow\ 0.85-(0.058526)\leq p \leq0.85+(0.058526)\\\\\Rightarrow\ 0.791474\leq p\leq0.908526\approx0.791\leq p\leq0.909[/tex]

The required confidence interval: [tex]0.791\leq p\leq0.909[/tex]
