Answer:

144° is the correct answer

sumpplement (angles that adds up to 180°)

: 180°-36°=144°

Answer:

B

Step-by-step explanation:

For the given situation, system of equations is represented by

3x + 4y = 4.25

5x + 2y = 4.75

"A system of equations is a finite set of equations for which we find the common solution."

According to question,

x represents number of apples

y represents number of oranges.

Two situations are given for which we need to find out which system of equations it represents.

Situation 1 : Thomas paid $4.25 for the three apples and four oranges , which can be represented by equation:

3x + 4y = 4.25

Situation 2: Casey paid $4.75 for five apples and two oranges, which can be represented by equation:

5x + 2y = 4.75

Hence we can conclude that Option B is correct.

Answer:

[tex]20.25\pi\:\mathrm{m^2}[/tex]

Step-by-step explanation:

Formulas to know:

Since we know the circumference, we can use formula for the circumference of a circle to find the circle's radius:

[tex]9\pi=2r\pi,\\9=2r,\\r=4.5[/tex]

Now we can plug in [tex]r=4.5[/tex] into the formula for an area of a circle:

[tex]A=4.5^2\pi=\boxed{20.25\pi\:\mathrm{m^2}}[/tex]

Answer:

20.25 pi

Step-by-step explanation:

The circumference of a circle is given by

C = 2 * pi *r

9 pi = 2 * pi *r

Divide each side by 2pi

9pi / 2 pi = 2 pi r / 2 pi

4.5 = r

Now we can find area

A = pi r^2

   = pi ( 4.5)^2

     20.25 pi

Answer:

r = 10.5

Step-by-step explanation:

using the Pythagorean theorem:

(7 + r)² = 14² + r²

49 + 14r + r² = 196 + r²

subtract r² from both sides of the equation:

14r + 49 = 196

subtract 49 from both sides:

14r  = 147

divide both sides by 14:

r = 10.5

option : c. 2x + 15 = 145

cuz, the angles are vertical opposite angles

Answer:

2x + 15 = 145

Step-by-step explanation:

vertical angles are congruent

=> (2x + 15)° = 145°

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

Explanation:

Part (a)

A regular triangular pyramid, aka regular tetrahedron, has all four triangles that are identical copies of one another. They are congruent triangles. This will apply to part (b) as well.

To find the area of one of the triangles, we'll use the formula

A = 0.25*sqrt(3)*x^2

where x is the side length. This formula applies to equilateral triangles only.

In this case, x = 20, so

A = 0.25*sqrt(3)*x^2

A = 0.25*sqrt(3)*20^2

A = 173.20508 approximately

That's the area of one triangle, but there are four total, so the entire area is about 4*173.20508 = 692.82032 which rounds to 693 sq cm.

The units "sq cm" can be written as "cm^2".

----------------------------

Part (b)

We'll use the same idea as part (a). But the formula to find the area of one triangle is much simpler.

The area of one of the triangles is A = 0.5*base*height = 0.5*6*4 = 12 sq cm.

So the area of all four triangles combined is 4*12 = 48 sq cm

This area is exact.

The area of each 2D flat net corresponds exactly to the surface area of each 3D pyramid. This is because we can cut the figure out and fold along the lines to form the 3D shapes.

Answer:

Exponential

Step-by-step explanation:

So lets look at the table.

When x = 1, y = 3

When x = 2, y = 9.

Hmmm, this doenst seem like x+number=y. It doesnt seem like a quadratic, where the values go up, then down, then up again. Or vise versa.

So this rules out linear and quadratic, for the x doesnt change by a constant, or change the direction of y.

This leaves exponential or none of the above.

When x = 3, y = 27

When x = 4, y = 81

This seems like a exponent, since:

3 to the first power is 3

3 to the second power is 9

3 to the third power is 27

and 3 to the fourth power is 81

Answer:

exponential function

Probability [Randomly choose plant Juan's mother want] = 3 / 5

Step-by-step explanation:

Given:

Total number of plant in store = 30 plants

Number of plant kind Juan's mother want = 18

Find:

Probability [Randomly choose plant Juan's mother want]

Computation:

Probability of an event = Number of favorable outcome / Total number of outcomes

Probability [Randomly choose plant Juan's mother want] = Number of plant kind Juan's mother want / Total number of plant in store

Probability [Randomly choose plant Juan's mother want] = 18 / 30

Probability [Randomly choose plant Juan's mother want] = 3 / 5

Answer:

y = (x - 2)² + 9

Step-by-step explanation:

To obtain the equation in vertex form use the method of completing the square.

Add/ subtract ( half the coefficient of the x- term)² to x² - 4x

y = x² + 2(- 2)x + 4 - 4 + 13

  = (x - 2)² + 9 ← in vertex form

Answer:

vertex form : y=(x-2)^2+9

Step-by-step explanation:

To convert a parabola from standard form y=x^2-4x+13 to vertex form, we complete the square.

first, complete the square using the x-terms, use the constant term to adjust and make a perfect square.

y=  x^2-4x+4   +  9

Factor the first three terms on the right-hand side.

y=(x-2)^2 + 9

the resulting express is then the vertex form, which means that

the vertex is at (x-2) = 0, x=2, and at y=9.

A. 0.75 cm

B. 1.6875 cm

C. 3.375 cm

D. 4.25 cm

Answer:

1.6875 cm³

Step-by-step explanation:

Given the dimension :

1.5 cm by 0.5 cm by 2.25 cm

The volume of a rectangular prism is given by :

Volume = Length * width * height

Volume, V = 1.5cm * 0.5cm * 2.25cm

Volume of prism = 1.6875 cm³

Hence, the volume of the rectangular prism is 1.6875 cm³
