Answer:
2.25 hours, or 2 hours and 15 minutes.
Step-by-step explanation:
All we do is 36/16 which is 2.25. 0.25 or 1/4 of an hour is 15 minutes. So, your answer is 2 hours and 15 minutes.
It takes 2 hour and 12 minutes for the cyclist to complete the ride of 36km distance.
What is unitary method?
The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
Total distance covered by cyclist= 36km
Average speed of the cyclist = 16km/hr
Therefore, using unitary method:
16 km distance takes time = 1hr
Therefore, 1 km distance takes time =(1/16)hr
Therefore, 36 km distance takes time = (1/16)×36 hr
=(1/4)×9 hr
=9/4 hr
=2.25 hr
=(2+0.25)hr
=2hr+0.25hr
=2hr+0.25×60minutes
=2hr and 15 minutes.
Hence, it takes 2hr and 15 minutes for the cyclist to complete 36 km rides.

Answer:
c=110+5x
Step-by-step explanation:
The equation that represents the total cost is C = 5x + 110.
What is Algebra?Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.
The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.
The expense of leasing a bowling alley for a party is $110, in addition to $5 an individual for food.
Let 'C' be the total cost and 'x' be the number of friends. Then the equation is written as,
C = 5x + 110
The equation that represents the total cost is C = 5x + 110.

At the mall in Miami, Roberto found a jacket he liked. The normal price was $120, but the jacket was on sale for 40% off. If Roberto has $50 to spend, does he have enough to buy the jacket? If not, how much more money does he need?
Answer: No, He will need $22 to add to his money to buy jacket.
Step-by-step explanation:
Normal price of jacket =$120,
New price = 40% off which means 40% Less than the Normal price
= 40/ 100 x 120
=0.4 x 120 = 48; 120 -48= $72
New Price = $72
Therefore Roberto with $50 to spend does not have enough to buy the jacket
He will need $72- $50 =$22 to add to his money to buy jacket.

1. Write an equation showing the relationship between 3 and y.
Type the equation in the box below.
I
Answer:
3x+2y
Step-by-step explanation:
Find the rectangles attached
Area of a rectangle = Length * Width
A = A1+A2
given
A = 30cm²
A1 = 3 * x
A1 = 3x
A2 = 2*y
A2 = 2y
Substitute
30 = 3x+2y
Hence the required equation is 3x+2y = 30
Answer: 3x + 2y = 30
Step-by-step explanation:
A = L x W
The sum of the rectangle is 30.
One angle is 3 and x, the other one is 2 and y.
Multiply 3 with x = 3x.
Multiply 2 with y = 2y
Then create your equation plugging in 30 as the answer to 3x + 2y

Silvio works at a car wash. He earns $50 per day and $12 per car washed. Silvio wants to earn at least $158 in 1 day.
Which inequality represents the number of cars (C) Silvio must wash to reach his goal?
Answer:
50+12x≥158
Step-by-step explanation:
starting with $50, adding $12 for every car washed (x), must be at least, but can be greater than, $158.
The required inequality for Silvio to earn more than $158 in one day is, $50 + 12x ≥ 158.
Given that,
Silvio works at a car wash. He earns $50 per day and $12 per car washed. Silvio wants to earn at least $158 in 1 day.
To determine the inequality represents the number of cars (C) Silvio must wash to reach his goal.
Inequality can be defined as the relation of the equation containing the symbol of ( ≤, ≥, <, >) instead of the equal sign in an equation.
Here,
Let the number of cars washed by Silvio be x,
According to the question,
Silvio works at a car wash. He earns $50 per day and $12 per car washed.
Total earning of the day = $50 + 12x
Silvio wants to earn at least $158 in 1 day. So, his total earnings of the day must be greater equal to $158.
$50 + 12x ≥ 158.
Thus, the required inequality for Silvio to earn more than $158 in one day is, $50 + 12x ≥ 158.

Evaluate ∛-512 Use pencil and paper. Explain how you can check that your result is correct. Show your work.
nothing (Type an integer or a simplified fraction.)
Answer:
3√512 = 8
Step-by-step explanation:
Step 1: Find the prime factors of 512
512 = 2 × 2 × 2 × 2 × 2 × 2 × 2 × 2 × 2
Step 2: Pair the factors of 512 in a group of three, such that they form cubes.
512 = (2 × 2 × 2) × (2 × 2 × 2) × (2 × 2 × 2)
512 = 23 × 23 × 23
Using the law of exponent, we get;
512 = 29 [am.an = (a)m+n]
Or
512 = (23)3 [(am)n = amn]
512 = 83
Step 3: Now, we will apply cube root on both the sides to take out the factor (in cubes) as a single term.
3√512 = 3√(83)
So, here the cube root is eliminated by the cube of 8.
Hence, 3√512 = 8
