The actual distance, in miles, between Dallas and Houston is 240 miles.
What is an expression?
The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
A scale for a map states that 2 inches equal 25 miles. If the distance from Dallas to Houston on the map is 19.2 inches.
2 inches = 25 miles
19.2 inches = ( 19.2 x 25 ) / 2
19.2 inches = 240 miles

That means that 1 inch on the map equals how many miles in real life?
... [time for you to think] ...
That's 12.5 miles. (simply 25 / 2 = 12.5).
So one inch on the map is equal to 12.5 miles in real life.
Starting from this....
So 1 inch on the map is equal to 12.5 miles in real life.
So 2 inches on the map is equal to 25 miles in real life. (2x12.5)
So 3 inches on the map is equal to 37.5 miles in real life. (3x12.5)
So 4 inches on the map is equal to 50 miles in real life. (4x12.5)
So 19.2 inches on the map is equal to <....> miles in real life (19.2 x 12.5).
For you to fill in the <...> using the steps I gave you.
Triangle B: Two sides have length 10 cm, and the included angle measures 60°. Triangle C: Base has length 15 cm, and base angles measure 40°.
Triangle D: All angles measure 60°.
Which triangle is not a unique triangle? Triangle A Triangle B Triangle C Triangle D
Answers
Answer:
Triangle D is not a unique triangle.
Step-by-step explanation:
Triangle A: All sides have length 12 cm.
such a triangle will be a unique triangle and it will be an equilateral triangle.
Triangle B: Two sides have length 10 cm, and the included angle measures 60°.
Such a triangle will also be unique because with the help of the given angle measure and and the angles opposite to equal sides are equal we can find the measure of those two angles.
and hence we can construct a triangle with the help of these information.
Triangle C: Base has length 15 cm, and base angles measure 40°.
Such a triangle will also be unique as a unique triangle could be constructed with the help of these information.
Triangle D: All angles measure 60°.
Such a triangle will be an equilateral triangle but we can't say it will be unique as we can construct infinite number of triangles with different side lengths.
Hence such a triangle is not unique.

1/8 of the lawn in 1/4 of an hour. That mean you would need a whole hour to do 4/8 or 1/2 of the lawn. So you would need two hours to do the whole lawn.
Step-by-step explanation:
Answer:
2 hours or you can say 120 minutes
Step-by-step explanation:
1/4 of an hour equals 15 minutes
1/8 = 15 minutes
4/8 = 1 hour = 60 minutes
8/8 = 2 hours = 120 minutes

Elena bought 320 tropical fish for a museum display. She bought 7 times as many triggerfish as parrotfish. How many of each type of fish did she buy?
Which is a system of equations to model the problem if x represents the number of parrotfish Elena bought and y represents the number of triggerfish she bought?
A.
x + y = 320
y = 7x
B.
x + 7y = 320
y = 7x
C.
x – y = 320
y = 7x
D.
x + y = 7
y = 320x

Answers
x parrot fish + y triggerfish = 320 total fish.
y = 7x shows that there are 7 times as many triggerfish.
2. C
x + y shows a total score of 425.
y = 2x - 70 shows that Michael's score, y, is 70 less (minus) than twice Kathryn's
3. write two equations
x + y = 27 total feet
2x + 3 = y
Substitute 2x + 3 for y in the first equation
x + (2x + 3) = 27
3x + 3 = 27
3x = 24
x = 8
Substitute 8 in to either equation to find the other length.
8 + y = 27
y = 19
The shorter piece is 8 and the longer piece is 19
4. x + y = 3200 people -> y = 3200-x
8x + 12y = 33,040 dollars
8x + 12(3200 - x) = 33040
8x + 38400 - 12x = 33040
-4x = -5360
x = 1340 (1340 children)
1340 + y = 3200
y = 1860 adults

79% of 67 miles is approximately 52.93 miles as per the concept of percentage.
To find 79% of 67 miles, we can use the concept of percentage as a fraction of a whole.
When we say "79% of 67 miles," we are asking for 79% of the total distance of 67 miles.
To calculate this, we convert the percentage to a decimal by dividing it by 100: 79% = 79/100 = 0.79.
Now, to find 79% of 67 miles, we multiply the decimal (0.79) by the total distance (67 miles):
0.79 x 67 miles = 52.93 miles
Therefore, 79% of 67 miles is approximately 52.93 miles.
In conclusion, when we talk about a percentage of a quantity, it represents a proportion of the total. In this case, 79% of 67 miles means 79% of the total distance of 67 miles, which is calculated by converting the percentage to a decimal and then multiplying it by the total distance. The result is approximately 52.93 miles.
