HELP!!! Lupitas Sister Is Purchasing Gas At The Gas Station. She Buys 10 Gallons Of Gas For $29.50Write

Answers

Answer 1

Step-by-step explanation:

10 gallons of gas is $29.50

10 gallons of gas = $29.50

10 gallons of gas / 10 = $29.50 / 10

1 gallon of gas = $2.95

Per x gallons of gas,

1 gallon of gas * x = $2.95 * x

x gallons of gas = $2.95 * x

Michelle has a round lamp to which she wants to add beads. The diameter is 12.2 inches. What is the circumference?

Answers

Answer: 38.34 inches

Step-by-step explanation:

The lamp is round which means that the circumference can be calculated by the formula:

= Pie * diameter

Pie = 22/7

Diameter = 12.2

Circumference = 22/7 * 12.2

= 38.34 inches

The function fx) = 2x + 3x + 5, when evaluated, gives a value of 19. What is the function's input value?

Answers

It’s C but I’m not entirely sure

The input value that gives an output of 19 is not listed in the answer choices. None of the options are correct.

What are the factors?

A number or algebraic expression that evenly divides another number or expression—i.e., leaves no remainder—is referred to as a factor.

Here,
We can start by setting up the equation:

2x² + 3x + 5 = 19

Subtracting 19 from both sides:

2x² + 3x - 14 = 0

(2x - 7)(x + 2) = 0

Using the zero product property, we can solve for x:

2x - 7 = 0 or x + 2 = 0

2x = 7 or x = -2

x = 7/2 or x = -2

Therefore, the input value could be either 7/2 or -2.

The answer choices do not include 7/2, but we can check both input values to see which one gives an output of 19:

f(7/2) = 2(7/2)^²+ 3(7/2) + 5 = 19.25

f(-2) = 2(-2)² + 3(-2) + 5 = 3

Thus, the input value that gives an output of 19 is not listed in the answer choices.

joseph is planting a garden. he plants 2 tomato plants for every 5 peppers. If joseph plants 14 tomato plants how many pepper plants does he plant?

Answers

Answer:

Ratio of tomato plant to that of pepper plant = 2:5

Let x be the number of pepper plants for 14 tomato plants.

Now, according to the question,

2:5 = 14:x

14×5 = 2x

x = 70/2 = 35 plants.

Step-by-step explanation:

So he/she would have 35 pepper plants to plant

What is the value of s?

Answers

Step-by-step explanation:

Sum of angles in a triangle = 180°.

=> s° + (s/7 + 3)° + (s/7 - 3)° = 180°

=> 9/7 * s° = 180°

=> s° = 180° * (7/9) = 140°

Hence the value of s is 140.

1) For a period of time, an island's population grows at a rate of 3.8% per year. If the current
population is 1543, what will the population be in 5.2 years?

Answers

Okay so 3.8% of 1,543 is 58.634 so then you would multiply it by 5.2 for years witch would be 304.8978 so add that to the original witch is 1543 so your answer would be 1847.8978 rounded up would be 1848

Will is w years old.
Ben is 3 years older.
1. Write an expression, in terms of w, for Ben's age.
Jan is twice as old as Ben.
2. Write an expression, in terms of w, for Jan's age.
If you add together the ages of Will, Ben and Jan the total comes to 41 years.
3. Form an equation and solve it to work out how old Will, Ben, and Jan are.

Answers

Answer:

Will is 8 years old, Ben is 11 years old, and Jan is 22 years old

Step-by-step explanation:

Since Ben is 3 years older, his age can be represented by w + 3

Jan is twice as old as Ben, so her age can be represented by 2(w + 3)

Set up an equation that adds up these expressions and sets it equal to 41:

(w) + (w + 3) + 2(w + 3) = 41

Simplify, add like terms, and solve for w:

(w) + (w + 3) + 2(w + 3) = 41

(w) + (w + 3) + (2w + 6) = 41

4w + 9 = 41

4w = 32

w = 8

So, Will is 8 years old.

Find Ben's age by adding 3 to this:

8 + 3

= 11

Find Jan's age by multiplying this by 2:

11(2)

= 22

So, Will is 8 years old, Ben is 11 years old, and Jan is 22 years old

A Boat is tied to the dock with a 25-foot rope. When the rope is pulled tight, the boat is 18 feet away from the base of the dock. The rope connects to the boat at the level of the water. What is the measure, to the nearest tenth of a degree, of x, the angle formed by the rope and the surface of the water?

Answers

Answer:

43.9°

Step-by-step explanation:

We solve the above question using the Trigonometric function of Cosine

cos x = Adjacent/Hypotenuse

From the question

Adjacent = Distance of the boat from the dock = 18 feet

Hypotenuse = Length of the rope = 25 feet

The angle formed by the rope and the surface of the water = x

Hence:

cos x = 18/25

x = arc cos (18/25)

x = 43.945519562°

Approximately θ = 43.9°

The angle formed by the rope and the surface of the water is given as 43.9°
