There are 40Student in a class. If the number of boys is 4less than the number of girls.find the number of boys.
Answer:
18
Step-by-step explanation:
Let number of girls be 'x'.
So, Number of boys = Number of girls - 4
= x - 4
Total number of students in a class = 40
Number of girls + Number of boys = Total number of students in a class
[tex] \longrightarrow [/tex] x + x - 4 = 40
[tex] \longrightarrow [/tex] 2x - 4 = 40
[tex] \longrightarrow [/tex] 2x - 4 + 4 = 40 + 4
[tex] \longrightarrow [/tex] 2x = 44
[tex] \longrightarrow [/tex] [tex] \sf \dfrac{2x}{2} = \dfrac{44}{2} [/tex]
[tex] \longrightarrow [/tex] x = 22
[tex] \therefore [/tex] Number of boys = 22 - 4
= 18

When Kim works 40 hours in a week, she earns $560. If she works only 35 hours, how much should she expect to earn?
Answer:
$490
Step-by-step explanation:
$560 divided by 40 is $14 an hour and 14 times 35 is 490, so $490.
Answer:
£490
Step-by-step explanation:
So you do 560 divided by 40, which is 14 then you × 35 by 40 =£490.

What is the solution to the inequality 75 > x/15?
______________________________________
A) x 1,125
C) x 5
______________________________________
Answer:
75 > x/15
Step-by-step explanation:
Step 1: Mulitply the 15 on both sides in order to get the x by it self.
Step 2: Simplify. 75 x (15) >x/15 x (15)
Step 3: The 15 on the right hand side cancels out leaving the x by itself.
Final Answr: 1125 > x which translates to x < 1125
The solution to the inequality is: A) (x > 1125)
To solve the inequality 75 > x/15, we need to find the range of values for x that satisfy the inequality.
First, we can start by isolating x on one side of the inequality. To do that, we can multiply both sides of the inequality by 15 (since 15 is a positive number, we don't need to reverse the inequality sign):
75 * 15 > x
Now, simplify the left side of the inequality:
1125 > x
So, the solution to the inequality is x < 1125, which means all values of x that are less than 1125 will satisfy the inequality.
Visually, if we plot the graph of y = x/15 and y = 75, we'll see that y = x/15 is a straight line with a positive slope of 1/15 passing through the origin, and y = 75 is a horizontal line parallel to the x-axis at the y-coordinate of 75. The solution to the inequality is the region below the line y = 75, which corresponds to the values of x that are less than 1125.
In real-world terms, this inequality represents a scenario where 75 is greater than some fraction of x divided by 15. To satisfy the inequality, x must be less than 1125. For example, if x represents the number of items sold in a store, this inequality would indicate that the store must sell fewer than 1125 items to meet the condition. The store's sales would need to be less than 1125 * 15 = 16,875 to maintain the inequality's validity. Beyond this point, if the store sells more items, the inequality would no longer hold true.

Answer:
9.404 cm
Step-by-step explanation:
A regular polygon with n sides inscribed in a circle of radius r will have a side length given by ...
s = 2r·sin(180°/n)
For r = 8 and n = 5, this gives a side length of ...

Step-by-step explanation:
What is the slope of the line that passes through the points (1, -8) and (-5, 10)?
Hi
You have two points A ( X;Y) and B ( X ; Y)
slope is : ( Yb -Ya) / (Xb -Xa )
A (1; -8) B ( -5 ; 10)
so : ' (10 - -8 ) / ( -5 - 1) = 18 /-6 = -3

494 divided by 14 is
remainde
Answer:
494 divided by 14 = 35 with a remainder of 4.
Step-by-step explanation:
The remainder is the integer "left over" after dividing one integer by another to produce an integer quotient (integer division).
To calculate remainder, work the division in your calculator as normal. Once you have the answer in decimal form, subtract the whole number, then multiply the decimal value that's left by the divisor of your original problem. The result is your remainder.
