Answer:
6/18
Step-by-step explanation:
Total amount of money that they have:
5 + 7 + 6 = 18
Since Dina has 6, the answer should be 6/18.
1/ 3
Step-by-step explanation:
5 + 7 + 6 = 18

Firefighters used a ladder 50 feet high to reach a window that was 30 feet above the ground. From the same point on the ground, the ladder is turned to across the street to reach a window that was 40 feet high.
Select all the true statements.
The width of the street, BM, is 70 feet.
The ground distance of the ladder from building B is 30 feet.
The ground distance of the ladder from building M is 30 feet.
The width of the street, BM, is 122 feet.
The length KL is 50 feet.
Answer:
First since 2 of the options ask for the width of BM lets solve for it using the Pythagorean theorem for both sides of point L:
a² + b² = c²
30² + b² = 50²
b² = 50² - 30²
b² = 1600
b = 40 Line BL = 40 ft
Since the ladder is 50 feet it is the same length on the other side as well
a² + b² = c²
40² + b² = 50²
b² = 50² - 40²
b² = 900
b = 30 line LM is 30 ft
SO line lm + line bl = 30 + 40 = 70 ft
A is true because ^
B isn't true because as we solved for earlier, BL is 40
C is true because line LM is in fact 30 ft as we solved for
D is not true because as we said earlier BM is 70
E is true because the same ladder was used on both sides of the street
Step-by-step explanation:
The width of the street, BM, is 70 feet. The ground distance of the ladder from building M is 30 feet. The length of KL is 50 feet.
What is Pythagoras's theorem?Pythagoras's theorem states that in a right-angled triangle, the square of one side is equal to the sum of the squares of the other two sides.
First, because two of the possibilities require the width of BM, let us solve for it using the Pythagorean theorem for both sides of point L.:
a² + b² = c²
30² + b² = 50²
b² = 50² - 30²
b² = 1600
b = 40
So, Line BL = 40 ft
So because the ladder is 50 feet long, it is also the same length on the other side.
a² + b² = c²
40² + b² = 50²
b² = 50² - 40²
b² = 900
b = 30
So, line LM is 30 ft
So line lm + line bl = 30 + 40 = 70 ft
Hence, the true statements are options (A), (C), and (E).

Step-by-step explanation:
Answer:
(x^2 - 5x^2 + 4x) / 2x + 8
Step-by-step explanation:
(x^2 - 16) / 2x + 8 * (x^3 - 2x^2 + x) / (x^2 + 3x -4)
(x^5 - 2x^4 - 15x^3 + 32x^2 -16x) / 2(x - 1)(x + 4)(x + 4)
x(x-1)(x-1)(x+4)(x-4) / 2(x - 1)(x + 4)(x + 4)
(x^3 -5x^2 +4x) / 2x + 8

Use the given x and y values to write a direct variation
equation. Enter your answer in the form y = kx.
x = 5, y = 50
The form is y = kx
Replace y and x:
50 = k(5)
Solve for k by dividing both sides by 5
K = 10
It took a car 4 days to travel 2686 miles. What was this car's average speed, in miles per hour? (round to the nearest mile per hour)
Answer:
28
Step-by-step explanation:
Well we know that in a day there are 24 hrs so in 4 days there will be 96 hrs
so the car travelled 2686 miles in 96 hours
2686/96= 27.9791666667
So the car's average speed is about 28

Find an equation for y in terms of x
Answer:
y = [tex]\frac{9}{x^2}[/tex]
Step-by-step explanation:
Given y is inversely proportional to x² then the equation relating them is
y = [tex]\frac{k}{x^2}[/tex] ← k is the constant of proportion
To find k use an ordered pair from the table
Using x = 3 when y = 1 , then
1 = [tex]\frac{k}{3^2}[/tex] = [tex]\frac{k}{9}[/tex] ( multiply both sides by 9 )
9 = k
y = [tex]\frac{9}{x^2}[/tex] ← equation of proportion

when it is thawed. Find the mass of the joint when thawed. *
Answer:
The mass of the meat when thawed is 7.72 kg (0.28 kg is lost)
Step-by-step explanation:
From the question, we are told that the weight loss amount is 8% of its initial weight
The mass lost here when thawed will be;
8/100 * 3.5 = 0.28 kg
So the mass of the joint will be;
8-0.28 = 7.72 kg
