can yall pls help me with this, it isn't that hard but i need to know how to solve it in steps and in how to narrow it down, ty.
Answer:
[tex]\frac{times}{days}[/tex] = [tex]\frac{20}{5}[/tex] = [tex]\frac{m}{30}[/tex]
you need to be consistant when setting up the proportions. The times always need to be on top and the days needs to always on bottom.
Cross multiply and solve for the variable.
20(30) = 5(m)
600 = 5m
120 = m
So, in 30 days the theatre showed 120 movies.

Pat threw a football 5 more than twice the number of yards, y, which Gary threw. Which expression can be used to find the number of yards Pat threw the football? *
**SHOW WORKK PLS
Answer:
2y+5
Step-by-step explanation:
Lets start with an expression for how many yards Gary threw. Since y is the variable given in the problem, we'll use that.
Yards Gary threw = y
We also know that Pat threw 5 more than twice the yards Gary did. First, we multiply Gary's yards by 2, then add 5 more. We end up with the expression:
Yards Pat threw = 2y+5

Find m∠EGF. please help!
Answer:
[tex] \large{ \tt{❃ \: EXPLANATION}} : [/tex]
We're provided - ∠AGB = 30° , ∠ DGC = 50° and ∠ EGF = 2x. We're asked to find out m ∠ EGF.Note that ∠ AGB , ∠ BGC and ∠ DGC form a straight line which means that their sum is equal to 180°.When two lines intersect , the angles formed opposite to each other are called verticall opposite angles. Vertically opposite angle are always equal to each other.[tex] \large{ \tt{❈ \: SOLUTION}} : [/tex]
Re-read the second point which I have mentioned above. Now , Set up an equation and solve for ∠ BGC .[tex] \large{ \tt{{ ♡ \: \angle \: AGB + \angle \: BGC \: + \angle \: DGC = 180 \degree}}}[/tex] [ Sum of angle in a straight line ]
[tex] \large{ \tt{⟶ \: 30 \degree + m \angle \:BGC \: + \: 50 \degree = 180 \degree}}[/tex]
[tex] \large{ \tt{⟶ \: m \angle \: BGC + 80 \degree = 180 \degree}}[/tex]
[tex] \large{ \tt{⟶ \: m \angle \:BGC= 180 \degree - 80 \degree}}[/tex]
[tex] \large {\tt{⟶ \: m \angle \: BGC = 100 \degree}}[/tex]
Hence , m ∠ BGC = 100°. Now , Re-read the third point which I have mentioned above and set up an equation and solve for x.[tex] \large{ \tt{❊ \: 2x = 100 \degree}}[/tex] [ being vertically opposite angles ]
[tex] \large{ \tt{⇢\frac{2x}{2} = \frac{100 \degree}{2} }}[/tex]
[tex] \large{ \tt{⇢ \: x = 50 \degree}}[/tex]
The value of x is 50°. Now :[tex] \large{ \tt{❁ \: REPLACING \: VALUE : }}[/tex]
[tex] \large{ \tt{ ➝ \: \angle \: EGF = 2x \degree = 2 \times 50 = \boxed{ \tt{100 \degree}}}}[/tex]
[tex] \boxed{ \boxed{ \large{ \tt{☄ \: OUR \: FINAL \: ANSWER : \boxed{ \underline{100 \degree}}}}}}[/tex]
Hence , Our final answer is 100° . And we're done![tex] \large{ \mathfrak{\# \: StayInAndExplore !\:☂ }}[/tex]

Answer:
100°
Step-by-step explanation:
Since ∠AD are 180°, and each side is the same,
180°-30°-50°=100°
Find the median of the set of data. Use a calculator if necessary. (Remember to put the list in numerical order.)
13, 7, 12, 9, 6
Median is _____.
6
9
12
13
Answer:
9
Step-by-step explanation:
To find the median of a set of data, arrange the data by value:
6, 7, 9, 12, 13
The number in the middle is the median.
Answer:
median is 9
Step-by-step explanation:
to find median u must arrange the data from ascending to descending order.
6 , 7 , 9 , 12 , 13
median = N + 1/2 (N means no of data)
= 5 + 1/2
= 6/2
= 3 th term
= 9

What is the shape that the question below
Answer:
Answer: D
Step-by-step explanation:
Let's just go through it.
No parallel sides A B C (if you believe the diagram) D F
Not regular (and no parallel sides) (if you believe the diagram) B C D F
No Lines of symmetry (that means that if you put a mirror on a line of symmetry) what you see as an image will be the same as what there is in front of the mirror. C D F
Has a reflex angle. (Just to remind you, it is an angle greater that 180 but less than 360
That lets out everybody but D.
Answer: D
Step-by-step explanation:
1. C and G have one set of parallel sides, and E, H, and I have two sets of parallel sides so they can be ruled out.
2. Regular shapes have sides that are all the same length and angles that all measure the same. A can be ruled out in addition to I which was already ruled out.
3. B can be ruled out now.
4. The only one with a reflex angle (greater than 180 degrees) is D.

Explanation:
At first the car isn't moving at all. This is at time 0. So this means the graph starts at the origin (0,0). Based on this alone, the answer is either choice B or choice C.
We can rule out choice C because the rates of change won't be constant to give those sharp straight lines. Instead, we have a gradual shift in speeds as the roller coaster progresses. So we'll have more of a curved shape as choice B shows.
Note that each time the car is going downhill, the speed goes up. On the flip side, as the car goes uphill, the speed goes down. So the direction of movement runs counter to the speed graph direction (one goes up, the other goes down).

Work Shown:
55% = 55/100 = 0.55
55% of 200 = 0.55*200 = 110 people prefer dogs
30% of 200 = 0.30*200 = 60 people prefer cats
Subtract the results: 110-60 = 50
The map above is being reduced by a scale factor of 1/3 and printed at the subway station. How many square inches will the new map take up?
new height = 24 inches
new length = 15 inches
Answer: 360 square inches
Step-by-step explanation: calculate area by multiplying length by height
The new map will take 360 inches² printed at the subway station.
What are the area and perimeter of a rectangle?We know the perimeter of any 2D figure is the sum of the lengths of all the sides except the circle and the area of a rectangle is the product of its length and width.
Given, the new map has a height of 14 inches and a new length of 15 inches.
We know the area of a rectangle (A) = (length×width), here the map is displayed as a banner so we can think of it as a portrait with height and length.
∴ Area of the new map = (height×length).
= (24×15) inches².
= 360 inches².
