Ella and some friends are going to a movie. Each movie ticket costs $5.
Create an equation that shows the relationship between how many friends, n, attend the movie and the total cost in
dollars, c.
Answer: c = 5n
Step-by-step explanation:
Cost of movie ticket = $5 per person
Number of people attending the movie = n
The total cost c, will be the multiplication of the cost of movie ticket per person by the total.number of people attending the movie. This will be:
c = 5 × n
c = 5n
Jackrabbits are capable of reaching speeds up to 40 miles per hour. How fast is this in feet per second? Round to the nearest whole number
Answer:
59 feet per second
Step-by-step explanation:
[tex]40 mph = \frac{40*5280feet}{1hour} \\40mph = 211200 feet/per/hour[/tex]
to convert 211200 feet per hour to feet per second, we need to know how many seconds are in one hour
60seconds * 60 minutes = 3600 seconds
[tex]211200/3600 = 58.66666666666.... =59[/tex]

Mr. Gatti is looking to buy some apples to bake a fresh & tasty apple pie. He goes to the store and sees two deals that are going on for apples: Deal A - 3/4 of a pound for $2.50 Deal B - LaTeX: 2\frac{2}{10}2 2 10 pounds for $5.25 1. Which is the better deal, and why? Explain your answer. Put your answer in $ per pound format
Answer:
Deal A is best
Step-by-step explanation:
Given
Deal A:
3/4 lb for $2.50
Deal B:
2/10 lb for $5.25
Required
Which deal is the better
To do this, we simply calculate the lb/dollar ratio
i.e.
[tex]Ratio = \frac{Amount}{Size}[/tex]
For Deal A:
[tex]Ratio = \$2.50/\frac{3}{4}lb[/tex]
[tex]Ratio = \$2.50 * \frac{4}{3}lb[/tex]
[tex]Ratio = \frac{\$10}{3}lb[/tex]
[tex]Ratio = \$3.33/lb[/tex]
For Deal B:
[tex]Ratio = \$5.25/\frac{2}{10}lb[/tex]
[tex]Ratio = \$5.25 * \frac{10}{2}lb[/tex]
[tex]Ratio = \frac{52.5}{2}lb[/tex]
[tex]Ratio = \$26.25/lb[/tex]
The better deal is the least expensive:
Hence: Deal A is better
Determine if the two triangles below are similar.
Answer:
they are similar because they both are equilateral triangles

Step-by-step explanation:
5*-9=-45
-45*-2=90
Answer:
90
Step-by-step explanation:
Let's solve this step by step:
(5) · (-9) · (-2)
First, there are two negatives in this equation. They will cancel each other out, to simply make 9 · 2:
5 · 9 · 2 =
Now, we do the multiplication:
5 · 9 · 2 = 45 · 2 = 90
90 is the answer!
Maggie makes a scale drawing of a deck. The scale for the actual deck to the scale drawing is 7 ft to 1 in. The
dimensions of the deck are: 28 ft (Wide) by 17.5 ft (Tall). What is the WIDTH of the deck in the drawing?
Answer:
The width is 2.5 inches
Step-by-step explanation:
Here, we want to state the width of the deck in the drawing given the scale for the actual scale to the scale drawing.
The given ratio is 7 ft to 1 in
Now we will have 17.5 to x in
x * 7 = 17.5 * 1
7x = 17.5
x = 17.5/7
x = 2.5 inches

slope=−4/3, y-intercept = 3
Answer:
The equation is y = [tex]-\frac{4}{3}[/tex] x + 3
Step-by-step explanation:
The form of the equation is y = m x + b, where
m is the slopeb is the y-intercept∵ The slope of the line is [tex]-\frac{4}{3}[/tex]
∴ m = [tex]-\frac{4}{3}[/tex]
→ Substitute it in the form of the equation above
∴ y = [tex]-\frac{4}{3}[/tex] x + b
∵ The y-intercept = 3
∴ b = 3
→ Substitute it in the equation above
∴ y = [tex]-\frac{4}{3}[/tex] x + 3
∴ The equation is y = [tex]-\frac{4}{3}[/tex] x + 3
A combination lock is opened with the correct sequence of three numbers between 0 and 49 inclusive. If a number can be used more than once, what is the probability of guessing those three numbers and opening the lock with the first try? (Write answer as a simplified fraction
Answer:
125,000
Step-by-step explanation:
Given that :
Sequence of three numbers chosen from 0 to 49 inclusive
Since numbers can be repeated ; hence numbers do not have to be different ;
Number of digits between (0 - 49 inclusive) = 50 digits.
Thus, there are equal number of possible choices for each of the three numbers, which is equal to the Number of digits :
1st number = 50
2nd = 50
3rd = 50
Hence,
(50³). = 50 * 50 * 50 = 125,000

To Prove:
ΔGHJ ≅ ΔLKJ
Statements Reasons
1. GH║KL 1. Given
2. J is the midpoint of HK 2. Given
3. JH ≅ JK 3. Definition of the midpoint of a segment
4. ∠JKL ≅ ∠JHG 4. Alternate interior angles
5. ∠GJH ≅ ∠KJL 5. Vertically opposite angles
6. ΔGHJ ≅ ΔLKJ 6. By ASA theorem of congruence
Statements Reasons
1. GH║KL 1. Given
2. J is the midpoint of HK 2. Given
3. JH ≅ JK 3. Definition of the midpoint of a segment
4. ∠JKL ≅ ∠JHG 4. Alternate interior angles
5. ∠GJH ≅ ∠KJL 5. Vertically opposite angles
6. ΔGHJ ≅ ΔLKJ 6. By ASA theorem of congruence
We have to prove the statement, ∠GHJ = ∠LKJ
Given; GH || KL, J is the midpoint of HK.
To prove; ∠GHJ = ∠LKJ
Given; J is the midpoint of HK,
By definition midpoint of a segment,
The midpoint is the middle part of the line segment J, it is equidistant from both endpoints it is the centroid of the segment of the endpoints.
JH ≅ HK
Then, by the property of alternate interior angles,
∠JKL≅ ∠JKH
Therefore, by the property of vertically opposite angles,
When two lines intersect they form four angles. Vertical angles are the angles that are opposite to each other. Any two intersecting lines form two pairs of vertical angles that are opposite to each other.
∠GJH ≅ KJL
By ASA congruence theorem,
When two triangles are congruent to each other - If two angles and the involved side of one triangle is equivalent to the two angles and the included side of the other triangle.
ΔGHJ ≅ ΔLKJ
Hence Proved.
