The function is called an if/else statement function lets you test if something is true or false and then do different things depending on which result you get.
An if/else statement is a type of control flow statement that allows a program to execute different instructions depending on the result of a logical expression. The statement begins with an if condition, followed by a set of instructions to be performed if the condition is true. If the condition is false, the program executes the instructions after the optional else statement. The syntax for an if/else statement looks like this: if (condition) { // Instructions to execute if condition is true } else { // Instructions to execute if condition is false } By using an if/else statement, a program can make decisions and perform different actions based on the results of a logical expression.

Jack brought a lunch box for $8 and 7 forks. He spent a total of $105. How much did each fork cost?
Answer:
13.85$
Step-by-step explanation:
105$-8$=97$
97$/7$=13.85$
Answer: About $13.86
Step-by-step explanation: To find how much the cost of the forks is, we need to subtract the value of the lunch box from the total cost, because we don't need to find the value of the lunch box. So:
105 - 8 = 97
So, now since he bought 7 forks, we need to divide 7 by 97. So:
97 / 7 = 13.857142857142858
So, we need to round to the nearest cent. So, the 7 is greater than 5, so we round up. So, we have $13.86 each. So, check, we do:
13.86(7) + 8
97.02 + 8
= 105.02
This is the closest he can buy for each fork is ABOUT $13.86. I hope this helps ;)

Answer:
The area of the compound shape is 5√10 cm²
Step-by-step explanation:
In the given shape, there is a rectangle and a right angle triangle.
i.e.,
Compund shape = Rectangle + Triangle
So,
Area of Compound Shape = Area of Rectangle + Area of Right Angle Triangle
For Rectangle;Length (l) = 2√5 cmWidth (w) = √8cm = 2√2 cmFormula;
A = l × wA = 2√5 × 2√2 cm
A = 4√10 cm²
For Triangle;Base (b) = 2 cmHeight (h) = 2√5 cmFormula;
A = ½ × base × heightA = ½ × √2 × 2√5 cm
A = 1 × √2 × √5 cm
A = √10 cm²
Now,
Area of Compound Shape = Area of Rectangle + Area of Right Angle Triangle
A = 4√10 cm² + √10 cm²
A = 5√10 cm²

A boat, sailing downstream, has traveled the same distance in 4.5 hours as it has traveled upstream in 5 hours. Calculate the speed of the boat if the speed of the current is 3 km/h.
EQUATION REQUIRED!!!
The speed of the boat in still water is - 37 km/h
let, the distance be 'x' km/hr.
And the speed of the boat in still water is 'S' km/hr.
According to the question,

1.5 litres of water are released from the faucet per minute.
It is given to us that -
There is a one quart jar
Water from the kitchen faucet fills the 1-quart jar in 10 seconds.
We need to ascertain the faucet's flow rate in gallons per minute.
We know that -
1 quart = 0.25 gallon ---- (1)
We also know that -
1 minute = 60 seconds
=> 60 seconds = 1 minute
=> 10 seconds = 10/60 = 0.16 minutes ----- (2)
Now, the flow rate can be calculated as -
Flow rate = Amount of water filled/Time taken ----- (3)
Substituting the values from equation (1) and (2) in equation (3), we have -
Flow rate = Amount of water filled/Time taken

the smaller triangle has a perimeter of 31 ft and an area of 40 ft2. if the larger triangle has a perimeter of 62 ft, what will it's area be?
If the larger triangle has a perimeter of 62 feet, its area will be 120 square feet.
We know that the perimeter of the smaller triangle is 31 feet, which means that the sum of the lengths of its three sides is 31 feet. We also know that the area of the smaller triangle is 40 square feet. We can set up the following equation to calculate the length of each side of the smaller triangle:
Side 1 + Side 2 + Side 3 = 31
We can then use the formula for the area of a triangle, A = bh/2, to calculate the length of the base and height of the smaller triangle. Since we know the area is 40 square feet, we can set up the following equation:
40 = (b)(h)/2
We can then solve this equation for b and h. We know that b + h = 31, so we can set up the following equation and solve for h:
h = 31 - b
Now that we know b and h for the smaller triangle, we can use the same formula to calculate the area of the larger triangle. Since we know that the perimeter of the larger triangle is 62 feet, we can set up the following equation to calculate the length of each side of the larger triangle:
Side 1 + Side 2 + Side 3 = 62
We can then use the following formula to calculate the area of the larger triangle:
A = (b)(h)/2
We know that b + h = 62, so we can set up the following equation and solve for h:
h = 62 - b
Now that we know b and h for the larger triangle, we can plug those values into the area formula and calculate the area of the larger triangle. The area of the larger triangle is 120 square feet. Therefore, if the larger triangle has a perimeter of 62 feet, its area will be 120 square feet.

a bicycle wheel has a diameter of 24 inches. there are 32 spokes evenly distributed around the wheel. how far apart is each spoke?
The diameter of a bicycle wheel is 24 inches. Around the wheel, there are 32 spokes that are spaced 48 meters away from one another.
The diameter of a circle is the distance measured through its center. The radius of a circle is the distance from the center to any point on the edge. Diameter divided by radius equals two, or 2r=d. 2 r = d . The simplest place to start would be to use a ruler to measure the distance between the circle's outside edges starting from its very center. The diameter would be that.
The diameter of the circle is the measurement at issue. The distance between the circle's center and its periphery can be measured.
far apart is each spoke (distance) = radius = diameter / 2
distance = 24/2
distance = 12
Since a wheel has 4 parts. so, 12*4 = 48 m

The dimensions of the rectangle are, length = 5 inch and width = 6 inch.
What is rectangle?
A rectangle in Euclidean plane geometry is a quadrilateral with four right angles. It can alternatively be explained in terms of an equiangular quadrilateral—a term that refers to a quadrilateral whose angles are all equal—or a parallelogram with a right angle. A square is an irregular shape with four equal sides.
Let, the length of a rectangle is 7 inches less than twice the width, w, of the rectangle.
Suppose,
width = w = x, then,
length = l = 2x - 7
Since the area of the rectangle is 30 square inches.
We know that.
Area of rectangle = length x width
30 = (2x - 7) x (x)
30 = 2x^2 - 7x
2x^2 - 7x - 30 = 0
2x^2 - 12x + 5x - 30 = 0
2x(x - 6) + 5(x - 6) = 0
(2x + 5)(x - 6) = 0
⇒ 2x + 5 = 0, x - 6 = 0
⇒ x = -5/2, x = 6
Since length is not negative.
Therefore, w = 6.
So, l = 2(6) - 7 = 12 - 7 = 5
Hence, the length is 5 inches and the width is 6 inches.

Eliot and William go running. Eliot ran for 8 mile, and William ran for 12 mile. Eliot finihed hi run in 40 fewer minute than William. If they run at the ame peed, for how long did William run?
William ran for 48 minutes since Eliot ran for 8 miles in 40 fewer minutes than William. They were running at the same speed.
Eliot and William both went running and ran for 8 miles and 12 miles respectively. Eliot finished his 8 mile run in 40 fewer minutes than William. This means that if the two of them were running at the same speed, it would take William 40 minutes longer than Eliot to finish his 12 mile run. To calculate how long William ran for, we can add 40 minutes to the time it took Eliot to run 8 miles. Since Eliot ran 8 miles in 40 fewer minutes than William, this means that Eliot ran 8 miles in the amount of time that William ran 12 miles. The total time William ran for is therefore 8 miles plus 40 minutes, which is 48 minutes.

If Brandon does 14 hours at the grocery store and 13 hours at the nursery the the total working hours = 96 hours
And if Brandon does g hours at the grocery store and n hours at the nursery then total working hours = (5g + 2n) hours
In this question we ahve been given Brandon has two summer jobs. During the week he works in the grocery store, and on the weekend he works at a nursery.
He gets paid $15 per hour to work at the grocery store and $20 per hour to work at the nursery.
We need to find the total working hours if he does 14 hours at the grocery store and 13 hours at the nursery.
Also, we need to find total working hours if he does g hours at the grocery store and n hours at the nursery.
We know that the number of week days = 5 and the number of weekend days = 2
if he does 14 hours at the grocery store during 5 days, then by unitary method he will work for 14 * 5 = 70 hours
Similarly, if he does13 hours at the nursery for 2 days, this means by unitary method he is working for 13 * 2 = 26 hours
So, the total number hours of working during a week,
70 + 26 = 96 hours
Let he does g hours at the grocery store
During week days total working hours would be,
= number of weekdays * number of working hours
= 5 * g
= 5g
and n hours at the nursery.
= number of weekend days * number of working hours
= 2n
so, the total hours would be 5g + 2n
Therefore, a) the total hours does he work if he does 14 hours at the grocery store and 13 hours at the nursery = 96 hours
b) the total hours does he work if he does gg hours at the grocery store and nn hours at the nursery = (5g + 2n) hours
