A) The stop sign is a regular octagon, so the measure of angle F must be 67.5°. What is the angle measure for angle L?
B) What is the measure of angle E? Explain how you know.
C) What is the measure of angle K?
D) What is the measure of angle H? Explain
Answer:
A) ∠L = 67.5°
B) ∠E = 112.5°
C) ∠K = 112.5°
D) ∠H = 67.5°
Step-by-step explanation:
A) ∠L is alternate interior to ∠F so it is equal to 67.5°
B) ∠E is supplementary to ∠F so ∠E = 180° - 67.5° - 112.5°
C) ∠K is alternate exterior to ∠E so ∠K = 112.5°
D) ∠H is a vertical angle to ∠F so ∠H is 67.5°

The cost of 4 tacos is $6.00.
What would be the cost for 10 tacos?
I need help answering this.
Answer:
$15.00
Step-by-step explanation:
To first answer; this we would need to figure out the cost of one taco
Since there are already 4 we would need to divide the price by the amount so you would do
6.00/4=1.5
And now that we have the price of one we can multiply it by 10
1.5*10=15
Can I please have brainliest :)
Answer:
$15.00
Step-by-step explanation:
Each taco is 6/4 = 1.50 so 10 tacos are $15.00
The equation a = 26w gives the area of a (in square feet) of a rectangle dance floor with a width of w feet help please this is hard
Answer:
26ft
Step-by-step explanation:
Complete Question:
The equation a = 26w gives the area of a (in square feet) of a rectangle dance floor with a width of w feet. Find its length
Formula for calculating the area of a rectangle is expressed as shown;
Area of a rectangle = Length * Width
Given the equation a = 26w that gives the area of a rectangle
On comparing with the formula;
Length * Width = 26w
Length = 26ft (by comparison)
Hence the length of the rectangle is 26ft
A window shaped like a parallelogram has an area of 73 2 3 square feet. The height of the window is 8 2 3 feet. How long is the base of the window?
Answer:
8 1/2 feet
Step-by-step explanation:
Here is the complete question
A window shaped like a parallelogram has an area of 73 2/3 square feet. The height of the window is 8 2/3 feet. How long is the base of the window?
A parallelogram is quadrilateral that has two pairs of parallel sides. The opposite sides equal in length
Area = base x height
73 2/3 = 8 2/3 x base
divide 73 2/3 by 8 2/3
221/3 x 3/26 = 8 1/2 feet
The eyes of a basketball player are 5 feet above the floor. The player is at the free throw line, which is 15 feet from the point on the floor directly below the center of the basket. The rim of a standard basketball hoop is 10 feet of the floor. What is the angle of elevation from the player's eyes to the center of the rim?
Answer:
18.44°
Step-by-step explanation:
The line of sight of the player to the rim, the height of the eyes of the player above the floor, the distance of the player from the center of the rim and the height of the center of the rim above the ground form a trapezium. The height of the center of the rim above the ground and the height of the eyes of the player above the floor form parallel sides.
Since The height of the center of the rim above the ground = 10 ft and the height of the eyes of the player above the floor = 5 ft, the height of the triangular part of the trapezium is 10 ft - 5 ft = 5 ft. The base of this triangle is parallel to the side of distance of the player from the center of the rim = 15 ft. So the base of this triangle is 15 ft. Since the angle of elevation Ф of the line of sight of the player to the rim is adjacent to this base = 15ft and opposite to the height of the triangle = 5ft,
By trigonometric ratios,
tanФ =opposite/adjacent = 5 ft/15 ft = 1/3
Ф = tan⁻¹(1/3)
Ф = 18.435°
Ф ≅ 18.44°

you need to equal them out, so it is actually 48 over 56 (times by 8) subtract 7 over 56 (times by 7). so the answer is 41 over 56.
Hannah decided to curl up and read a good book. She started reading at 10:00 a.m. and
finished reading at 11:43 a.m. How much time did she spend reading? (SHOW YOUR WORK PLEASE!! I WILL GIVE BRAINLIEST TO BEST ANSWER WITH EXPLANATION BUT I NEED 2 PEOPLE TO ANSWER TO DO THIS)
Answer:
1 hour and 43 minutes or 103 minutes
Step-by-step explanation:
There are 60 minutes in an hour, so from 10 am to 11 am is 60 minutes. The additional 43 minutes need to be combined with the 60 minutes, which will give you 103 minutes.
Answer:
1 hour and 43 minutes
Step-by-step explanation:
10:00am+ 1 hour = 11:00 am

Answer:
5) r=40 gals/min
6) r= 125 mm/hr
7) $2600
8) d = 36 in
9) h= 1176 m
Step-by-step explanation:
5) r=v/r
r= 15,600 gals ÷ 390 mins
r= 40 gals/min
6) r=v/t
r= 1000mm ÷ 8 hrs
r= 125 mm/hr
7) $4500 - $1900 = $2600
8) C = Pi x d
c/Pi =d
113 in/3.14 = d
d = 36 in
9) Formula for h
h = 2 x a/b
h = 2 (84m2/12m)
h = 2 (7056/12)
h = 2(588)
h = 1176 m

Jodi's best score on a video game is 50 points. Mark's best score on the game is 1.5 times as much as Jodi's best score. How many points did Mark score on the video game? Mark's best score on the game is points. Virginia's best score is only 0.3 times Jodi's best score. How many points did Virginia score on the game? Virginia's best score is points.
Answer:
a) Mark's best score on the game is 75 points.
b) Virginia's best score is 15 points.
Step-by-step explanation:
Jodi's best score on a video game is 50 points.
a) Mark's best score on the game is 1.5 times as much as Jodi's best score. How many points did Mark score on the video game?
Mark's best score on the game is calculated as:
1.5 times as much as Jodi.
Jodi's best score = 50 points
= 1.5 × 50 points
= 75 points
b) Virginia's best score is only 0.3 times Jodi's best score. How many points did Virginia score on the game? Virginia's best score is points.
Virginia's best score on the game is calculated as:
0.3 times as much as Jodi.
Jodi's best score = 50 points
= 0.3 × 50 points
= 15 points
Virginia's best score is 15 points.

A support wire for a utility pole is 40 feet long. The wire is attached to the ground 24 feet from the base of the pole. How tall is the utility pole?
Answer:
32 feet
Step-by-step explanation:
given the following;
Length of wire = 40feet = hypotenuse
Base of the pole = 24 feet = adjacent
Required
Height of the pole (opposite)
Using the pythagoras theorem;
hyp^2 = opp^2 + adj^2
40^2 = 24^2 + opp^2
1600 = 576 +opp^2
opp^2 = 1600 - 576
opp^2 = 1024
opp = √1024
opp = 32feet
Hence the utility pole is 32feet tall

After one side of a square was enlarged by 2 inches and the other side was enlarged
by 3 inches, the area of the shape was doubled.
What was the side of the square?
Answer:
6 inches
Step-by-step explanation:
basically, first write an equation
2x^2 = x^2 + 5x + 6
then simplify this into
x^2 = 5x + 6
then use sum-product pattern and factor
(x - 6)(x + 1) = 0
then split into two equations
x - 6 = 0, x + 1 = 0
so, you have x = 6 and x = -1
because it can't be negative, 6 is your answer
