of 54 cities, 7 have a lake and 25 have a river running through them. What fraction of these 54
cities have a lake or a river running through them? Show your work.
Answer:
32/54 which could reduce to 16/27 or 59.3%
Step-by-step explanation:
7+25=32 have a river or lake
54 total cities
32/54=59.3
4. What number is 16% of 44
n = 16 x 44 (n = 704)
044 = 0.16 x n (n = 275)
O n = 0,16 x 44 (n = 7)
0.16 = n x 44 (n = 0.4)

Answer:
Step-by-step explanation:
1) Number of white chocolate bars = x
Number of dark chocolate bars = y
Total bars = 15
x + y = 15 --------------(I)
Total cost = Php. 340
20x + 25y = 340 ----------------(II)
2) We can use elimination method to solve this equations.
Multiply equation (I) by (-20) and then add the equations.
(I)* (-20) -20x -20y = - 300
(II) 20x + 25y = 340 {Now add and x will be eliminated}
5y = 40
y = 40/5
y = 8
Substitute y = 8 in equation (I)
x + 8 = 15
x = 15 - 8
x = 7
3) Number of dark chocolate bars = 8

4. Jake can paint a room in 7 hours, and Karen can paint the same room in 5
hours. How long will it take to paint the room if they work together?
Answer:
6 hours
Step-by-step explanation:
( 7h + 5h)/2 =6h
ANSWER:
It would take them about 3 hours to paint the room together.
EXPLANATION:
The least common denominator of 7 and 5 would be 35, so if we set 7x+5x equal to 35, the answer rounds up to 3. (or 2.9 if rounded to the nearest tenth.)
The distance in miles in the distance in inches vary directly on a map. The legend on the map shows that 16 miles are represented by 0.5 inches. What is the actual distance between the two cities if they are 3 inches apart on the map? In the situation distance in =x.
A) 96 miles
B)72miles
C)80miles
D)104miles
The actual distance between the two cities is 96 miles.
What is Ratio?The ratio is defined as a relationship between two quantities, it is expressed as one divided by the other.
We have been given that the map shows that 16 miles are represented by 0.5 inches.
Let x miles would be the actual distance between the two cities
When they are 3 inches apart on the map
According to the given situation, we can write the ratio would be as:
16 miles : 0.5 inches = x miles : 3 inches
⇒ 16/0.5 = x/3
Apply the cross-multiplication operation,
⇒ 0.5x = 48
⇒ x = 48/0.5
⇒ x = 96
Therefore, the actual distance between the two cities is 96 miles.

Find the measure of the missing angle.
a
20°
Answer:
160 degrees
Step-by-step explanation:
That is a straight line, meaning that the sum of a and 20 has to equal 180.
a + 20 = 180
a = 180-20
a = 160

Answer:
24y^3/x^5
Step-by-step explanation:
Since 6x and 4x are not in a parentheses, they are not being powered by anything. Therefore, those stay on the numerator side.
Anything to the power of something times another to the power of something is always added together. Since -1 + (-4) is -5, x would end up having a power of -5, which would just make it go on the denominator side with just a power of 5.
Same rule with y follows. This would make it 5+ (-2) = 3. Since this is a positive power, it stays at the numerator side.

Write a list of steps that are needed to find the measure of ∠B.
9514 1404 393
Answer:
∠B = 41°
Step-by-step explanation:
Step 1: Recognize that ∠B and ∠A are "remote interior angles" with respect to the exterior angle at C. Hence their sum will be equal to the measure of the exterior angle.
Step 2. Compute angle B as the difference between the exterior angle at C and the interior angle at A:
113° - 72° = ∠B = 41°
Which graph represents a linear function?
Answer:
Please check the explanation below.
Step-by-step explanation:
Note: As you forgot to mention the graphs of a linear function. But, let me clear your concept with an example of a linear function.
We know that linear function is of the form
y = mx+b
where
m is the slopeb is the y-interceptWe know that the graph of a linear function is a straight line because the highest power of the exponent of the x variable is 1.
Thus, y = mx+b represents a straight line.
For example,
Let the linear function
y = 2x+3
comparing with the linear function of the form y = mx+b
The slope = m = 2The y-intercept b = 3As the highest power of the exponent of a variable is 1, therefore y = 2x+3 represents a straight line.
The graph of the linear function y = 2x+3 is also attached below.

Answer:
The slobe would be negative
because from the height, it is decreasing
Answer: b. negative
=======================================================
Explanation:
Each time x goes up, y goes down. This inverse relationship means we have a negative slope.
----------
We can apply the slope formula to get further proof.
Let's say we pick the first two columns to form the points (1,24) and (2,18)
Then apply the slope formula to get...
m = (y2-y1)/(x2-x1)
m = (18-24)/(2-1)
m = -6/1
m = -6
The slope is -6.
----------
Visually we can see that the line goes downhill as you move from left to right. See the diagram below.
True or False: (1, 3) is a solution to the system of linear equations shown
below.
y= 4x - 1
y = x + 2
Answer:
True
Step-by-step explanation:
(1, 3) is a solution to the system of linear equations shown is true
Answer:
True
Step-by-step explanation:
You can substitute x = 1 and y = 3 into both equations and see if it's true or not.
y = 4x - 1
becomes
3 = 4(1) - 1
3 = 4 - 1
3 = 3
True
y = x + 2
becomes
3 = 1 + 2
3 = 3
True
Since both equations come out true, this (1, 3) is a solution.
