the scale on a map is 1:25000. how many km on the ground is represented by 6cm on the map?
Given:
The scale on a map is 1:25000.
To find:
How many km on the ground is represented by 6cm on the map?
Solution:
Let x be the km on the ground.
We know that,
1 km = 1000 m
1 m = 100 cm
So,
1 km = 100,000 cm
x km = 100,000x cm
The scale on a map is 1:25000. It means the ratio of map and ground is equal to 1:25000.
[tex]\dfrac{1}{25000}=\dfrac{6}{100,000x}[/tex]
[tex]\dfrac{100,000x}{25000}=6[/tex]
[tex]4x=6[/tex]
[tex]x=\dfrac{6}{4}[/tex]
[tex]x=1.5[/tex]
Therefore, 1.5 km on the ground is represented by 6cm on the map.

Answer:
The Expression h(-7) represents the output of h corresponding to the input of -7
Step-by-step explanation:
Answer:
C. The expression h(-7) represents the output of h corresponding to the input of -7.
Step-by-step explanation:
In a function written in function notation, the term h(x) represents the output value while x represents the input value, and h is the name of the function.
So, the expression h(-7) represents the output of h corresponding to the input of -7.

Mai biked 5 1/4 miles today, and Noah biked 2 1/2 miles. How many times the length of Noah’s bike ride was Mai’s bike ride?
Answer:
The length of Mai's bike ride was 2.1 times the length of Noah's ride.
Step-by-step explanation:
Mai biked 5 1/4 miles today
So he biked, in miles:
[tex]5 + \frac{1}{4} = \frac{5*4 + 1}{4} = \frac{20+1}{4} = \frac{21}{4}[/tex]
Noah biked 2 1/2 miles.
So, in miles, he biked:
[tex]2 + \frac{1}{2} = \frac{2*2 + 1}{2} = \frac{4+1}{2} = \frac{5}{2}[/tex]
How many times the length of Noah’s bike ride was Mai’s bike ride?
We divide the Mai distance by Noah's distance. In a division of fractions, we multiply the numerator by the inverse of the denominator. So
[tex]\frac{\frac{21}{4}}{\frac{5}{2}} = \frac{21}{4} \times {2}{5} = \frac{21*1}{2*5} = \frac{21}{10} = 2.1[/tex]
The length of Mai's bike ride was 2.1 times the length of Noah's ride.

Latonya bought hotdogs for $1.29 each to sell in the
concession stand. She sold them for $3.00 each. What is
the approximate percent increase in price?
Answer:
57%
Step-by-step explanation:
Given data
Cost price = $1.29
selling price= $3
Change= 3-1.29
Change= $1.71
Hence the % increase
= 1.71/3*100
= 0.57*100
= 57%
Which equation represents a line which is perpendicular to the line y= -5/4x - 4?
A. 4y - 5x = -4
B. 4x - 5y = 15
C. 5x + 4y = -8
D. 4x + 5y = 40
Answer:
b
Step-by-step explanation:
4x-5y=15
-5y=-4x+15
y=4/5x+15
4y - 5x = -4 represents the line which is perpendicular to the line y= -5/4x - 4. Option A is correct.
What are perpendicular lines?Two lines are perpendicular to each other if the product of their slopes is equal to -1.
Given,
y= -5/4x - 4
Slope of this line =m1 = -5/4
Let, slope of required line be m2
Then, (m1)(m2) = -1
(-5/4)m2 = -1
m2 = 4/5
The required line has slope = 4/5
Hence, 4y - 5x = -4 has slope equal to 4/5.
