Answer: 52
Step-by-step explanation:
Since the value of y varies directly with x, y = kx where k is a constant.
Since x=104, then y=78, we need to calculate the constant k. This will be:
y = kx
78 = 104k
k = 78/104
k = 0.75
What is the value of x when y=39?
Since y = =kx
39 = 0.75x
x = 39/0.75
x = 52

A mountain climber at the top of the mountain 160 metres above ground level observes the angle of depression of the two cars parked on the road side at 60 degree (second car) and 30degree (first car) respectively. Find the distance : 1. from the base of the mountain to the first car, 2. from the base of the mountain to the second car and, 3. between the two cars.
Answer:
a. distance between the base of the mountain and the first car, d = 277 m
b. distance between the base of the mountain and the second car, s = 92 m
c. distance between the two cars = 185 m
Step-by-step explanation:
a. Since the angle of depression is 30°, the interior angle = (90 - 30)° = 60°
Let the distance between the base of the mountain and the first car be d, and height of the mountain = 160 m
tan 60° = d/160 m
d = tan 60° * 160 m
distance between the base of the mountain and the first car, d = 277 m
b. Since the angle of depression is 60°, the interior angle = (90 - 60)° = 30°
Let the distance between the base of the mountain and the second car be s, and height of the mountain = 160 m
tan 30° = s/160 m
s = tan 30° * 160 m
distance between the base of the mountain and the second car, s = 92 m
c. distance between the two cars = 277 - 92
distance between the two cars = 185 m

Some one please help and find the domain and range. If your not sure about your answer don’t give the answer unless your 100% sure.
Answer:
Domain x=1 and range is 0≤f(x)≤3
Step-by-step explanation:
Domain corresponds to the value of x and range corresponds to the value of y
Here we see the graph exists at x=1 so the domain is x=1 or simply 1 and the range is a range of values from 0 to 3 so we write it in the way

Which multiplication expression is equal to 5/6 divided 1/2 ?
A: 6/5 times 1/2
B: 5/6 times 1/2
C: 6/5 times 2/1
D: 5/6 times 2/1
Answer:
D
Step-by-step explanation:
Another way to divide fractions is to multiply by the reciprocal, which is basically the fraction with the denominator put on top and the numerator put on the bottom.
The reciprocal of 1/2 is 2/1, so the correct answer choice is D
Hope this helps! Good luck :)
The multiplication expression that is equal to 5/6 ÷ 1/2 is 5/6 times 2/1, which simplifies to 5/3.
Thus, option (D) is correct.
Given: 5/6 ÷ 1/2
To find the reciprocal of 1/2, invert the fraction, which means switching the numerator and denominator:
Reciprocal of 1/2 = 2/1
Now, multiply the first fraction (5/6) by the reciprocal (2/1):
= (5/6) × (2/1)
Multiplying the numerators and denominators:
= (5 × 2) / (6 × 1)
= 10/6
To simplify the fraction, divide the numerator and denominator by their greatest common divisor (GCD):
GCD(10, 6) = 2
= (10/2) / (6/2)
= 5/3
Therefore, the equivalent multiplication expression is5/6 times 2/1.

Restaurant A Restaurant B x y 5 10 20 30 v 1 2 3 50 75 Which compares the slopes of the lines created by the tables? 1 O The slope of the line for Restaurant B is 5 times greater than the slope of the line for Restaurant A. The slope of the line for Restaurant B is 2 times greater than the slope of the line for Restaurant A The slope of the line for Restaurant B is 5 times greater than the slope of the line for Restaurant A. The slope of the line for Restaurant B is 10 times greater than the slope of the line for Restaurant A.
Answer: the correct Answer should be B
Step-by-step explanation:
The correct option is slope of the line for restaurant B is 2 times greater than the slope of the line for restaurant A.
What is Slope?Slope of a line is the ratio of the change in y coordinates to the change in the x coordinates of two points given.
Given the values of x and y for restaurant A as,
x : 10 20 30
y : 1 2 3
Consider the point (10, 1) and (20, 2).
Slope of the linear relationship of x and y of restaurant A is,
Slope = (2 - 1) / (20 - 10)
= 1/10
Given the values of x and y for restaurant B as,
x : 25 50 75
y : 5 10 15
Consider the points (25, 5) and (50, 10).
Slope of the linear relationship of x and y of restaurant B is,
Slope = (10 - 5) / (50 - 25)
= 5 / 25
= 1/5
= 2 × 1/10
= 2 × Slope of line for restaurant A
Hence slope of the line for restaurant B is 2 times the slope of line for restaurant A.

A furniture store delivers for $40 plus $0.75 for every mile they have to travel from the store. Which function represents the cost for delivery, c(m), given the distance from the store, m, in miles, and how much does delivery cost for someone who lives 60 miles from the store?
Answer:
$85Step-by-step explanation:
le the total cost be y
and the number of miles be x
the expression for the total can be modelled linearly as
y=mx+c
given that
c=$40
m=$0.75
for x==60miles
we can substitute into the expression to solve for y we have
y=0.75(60)+40
y=45+40
y=85
The cost to deliver at a distance of 60miles is $85

The Hernandez family orders 3 large pizzas. They cut the pizzas so that each pizza has the same number of slices, giving them a total of 24 slices.
The Wilson family also orders several large pizzas from the same pizza restaurant. They also cut the pizzas so that all their pizzas have the same number of slices. For the Wilson family, the equation y = 10x represents the relationship, where x represents the number of pizzas and y represents the number of total slices.
Which statements best describe the pizzas bought by the Hernandez and Wilson families? Select TWO options.
A. For the Hernandez family, the equation y = 3x represents the relationship between the number of slices and number of pizzas, where x represents the number of pizzas and y represents the number of total slices.
B. For each family, a graph of the relationship between number of pizzas, x, and number of slices, y, goes through the point (0, 0) and is a straight line.
C. The Hernandez family’s slices are smaller than the Wilson family’s slices.
D. If the Wilson family ordered 3 large pizzas from the same restaurant as the Hernandez family, they would have more slices than the Hernandez family after each family cut their pizzas into slices.
E. The constant of proportionality is 10 for the Wilson family, but cannot be determined for the Hernandez family.

The area of a rectangular wall of a barn is 12 square feet. Its length is 14 feet longer than the width. Find the length and width of the wall of the barn.
Answer:
w = 0.81 ft
l = 14.81 ft
Step-by-step explanation:
The equation of the area of a rectangle is given by:
[tex]A_{r}=l*w[/tex]
But we know that l=14+w and [tex]A_{r}=12 ft^{2}[/tex]
So we will have:
[tex]12=(14+w)*w=14w+w^{2}[/tex]
[tex]w^{2}+14w-12=0[/tex]
Solving this quadratic equation we have:
w = 0.81 ft
We just take the positive solution
So, the length will be l = 14 + 0.81 = 14.81 ft
