Hello! A triangle has angles that sum up to 180°. So first off, let's solve for the angle of the other triangle. 83 + 31 gives us 114. 180 - 114 is 66. So the angle for the first triangle is 66°. The opposite angle would be the same. Finding the measurement of the other triangle gives us the measurement of x, because the angles are the same. So x = 66°.

Is this right? If not let me know and explain how if u can. (No link <3)

Answer:

9/35

Step-by-step explanation:

There are a total of 15 bulbs to choose from randomly. First a new bulb is chosen. Chance is 9/15 because 9 out of 15 are new.

Then there are only 14 bulbs left. Then a used bulb is chosen. Chance is 6/14 since 6 out of remaining 14 are used.

Total chance for this to happen is 9/15 * 6/14 = 54/210 = 9/35.

Lori works as a cartoonist for a teen magazine.The time she spent sketching is given by the equation m=12s, where mis the number

Vera_Pavlovna [14]

Answer:

Lori spends 9 minutes on sketching $\frac{3}{4}$ th of a sketch.

Step-by-step explanation:

Given equation:

$m=12\ s$

where $m\rightarrow$ number of minutes Lori spends on sketching

and $s\rightarrow$ number of sketches Lori makes.

We need to calculate the time spent by Lori in sketching $\frac{3}{4}$ of a sketch.

So we know the value of $s=\frac{3}{4}$ as $s$ represents number of sketches and in this situation Lori has sketched only a fraction of a painting.

So we plugin $s=\frac{3}{4}$ in the equation and calculate $m$ which is time spent by Lori sketching $\frac{3}{4}$ th of a sketch.

$m=12\ \frac{3}{4}$

$m=\frac{36}{4}$

∴ $m=9$ minutes (Answer)

∴ Lori spends 9 minutes on sketching $\frac{3}{4}$ th of a sketch.

Match the real-world problem to its constant of proportionality.

BabaBlast [244]

Answer:

a. $18.36 for 3 pizzas : k = 6.12

b. $4.17 for 3 pounds of bananas . k = 1.39

c. $16.48 for 4 pounds of potatoes . k = 4.12

d. 2 cups of flour to make 24 cookie . k = 2

Step-by-step explanation:

PROPORTIONALITY:

Two quantities x and y are said to proportional to each other

if for x ∝ y , x = y k.

Here, k i s called the PROPORTIONALITY CONSTANT.

⇒ $x \propto y \implies k = \frac{x}{y}$

Now, for the given quantities:

a. $18.36 for 3 pizzas [box]

Here, $k = \frac{18.36}{3} = 6.12$

So, the proportionality constant is 6.12.

b. $4.17 for 3 pounds of bananas [box]

Here, $k = \frac{4.17}{3} = 1.39$

So, the proportionality constant is 1.39.

c. $16.48 for 4 pounds of potatoes [box]

Here, $k = \frac{16.48}{4} = 4.12$

So, the proportionality constant is 4.12.

d. 2 cups of flour to make 24 cookies

Here, $k = \frac{24}{2} = 12$

So, the proportionality constant is 12

Which are true about the pyramid? Check all that apply.

Travka [436]

The statements that are true about the pyramid are

The base of the pyramid is a square with four sides, each measuring 756 feet.

The slant height of the pyramid is 612 feet.

All four triangular faces are congruent.

The pyramid has four lateral faces.

<h3>Properties of a Square pyramid </h3>

From the question, we are to determine the statements that are true about the pyramid

The diagram shows a square pyramid,

The length of a side of its base is 756 ft

and

The height / altitude of a triangular face is 612 ft

Since the pyramid is a square pyramid,

Then, the base must be a square with each side measuring 756 feet

∴ The first statement is true

Since the height of a triangular face is 612 ft,

Then,

∴ The slant height of the pyramid is 612 feet

NOTE: Slant height of a pyramid is the altitude of the triangle comprising a lateral face

Thus, the second statement is true

Since the triangular faces each have a base of 756ft and a height of 612 ft,

Then,

All four triangular faces are congruent

∴ The fourth statement is true

NOTE: Lateral sides of a solid are the faces on the sides of the shape

The pyramid has four lateral faces which are each a triangle

∴ The last statement is true

Hence, the statements that are true about the pyramid are

The base of the pyramid is a square with four sides, each measuring 756 feet.

The slant height of the pyramid is 612 feet.

All four triangular faces are congruent.

The pyramid has four lateral faces.
