the scale of a map says that 6cm represents 15 km. what distance on the map represents an actual distance of 6 kilometres
Answer:
2.4 cm
Step-by-step explanation:
[tex] \frac{6}{15} = \frac{x}{6} \\ \\ 15x = 6 \times 6 \\ \\ 15x = 36 \\ \\ x = \frac{36}{15} \\ \\ x = 2.4[/tex]

Answer:
The third choice
Step-by-step explanation:
We need to find the slope and y-intercept of the line and then put it into y = mx = b form. To find the slope, pick a point on the line; I will use (-2, 5); count how many units up you need to go to get to the next point on the line, which in this case it would be 3. The count how many to the right or left you would need to go, which is 1 to the left. Moving left means a negative, so it is -1. Your slope fraction would be [tex]\frac{3}{-1}[/tex] , since slope is rise over run. You can sub this fraction in for m in y = mx + b, which will give you a revised equation of y = -3x = b. To find the y intercept, or b, just find the point where the line crosses the y-axis, which is -1. So, the equation is now y = -3x - 1.The correct answer is third choice.
A squirrel jumps along the number line. Each of its jumps is 5 units long. The squirrel sometimes jumps to the right and sometimes to the left. It starts at point 6. Can it land at this point? (The point is 101)
9514 1404 393
Answer:
yes
Step-by-step explanation:
For some integer n, the squirrel lands on numbers that are ...
5n +6
We want to see if n is an integer when ...
5n +6 = 101
5n = 95
n = 19 . . . . yes, an integral number of jumps will get the squirrel to 101

The probability that Terry buys a sandwich is 0.4.
The probability that Terry gets the bus is 0.9.
Assuming the events are independent, what is the probability that Terry buys a sandwich and gets the bus?
Answer:
The probability that Terry buys a sandwich and gets the bus is 0.36
Step-by-step explanation:
When two events are called independent, it means that the happening of one event doesn't affect the happening of other event.
Let A be the event that Terry buys a sandwich
Let B be the event that Terry gets the bus
Then
[tex]P(A) = 0.4\\P(B) = 0.9[/tex]
When two events are independent, their probabilities are multiplied i.e.
[tex]P(A\ and\ B) = P(A) * P(B)\\= 0.4 * 0.9\\= 0.36[/tex]
Hence,
The probability that Terry buys a sandwich and gets the bus is 0.36

A grocery store is selling peaches for $0.98 per pound. Is this a function or Not function
Answer:
This is a function. Use y=mx+b equation
Step-by-step explanation:
To find the x and y values, simply plug in 0.98 to m. For every pound of peaches, you pay $0.98. The equation would be y=0.98x, where x is the number of pounds of peaches and y is the total cost.

Answer:
x=17, y=9
Step-by-step explanation:
(5x - 38)° = (3x - 4)°
2x = 34
x=17
(5(17)-38))=47
90°+47°+(7y-20)=180°
7y-20=43°
y=9
The value of x is 17 and y is 9.
What are the properties of parallel lines?Following are the properties of parallel lines,
The pairs of vertically opposite angles are equal.The pairs of corresponding angles are equal.The pairs of alternate exterior angles are equal.The pairs of alternate interior angles are equal.Given:
<1 = 7y -20
<2 = 5x - 38
<3 = 90
exterior angle = 3x -4
Using alternate interior angle
5x - 38 = 3x-4
2x = 34
x=17
So, <2 = (5(17)-38))
<2 =47
Using angle sum property
90°+47°+(7y-20)=180°
7y-20=43°
y=9
Hence, the value of x is 17 and y is 9.
