Simplify: 40 - 24÷ {7 + (7-15)}
please I need this answer ASAP
Answer: 64
Step-by-step explanation:
40 - 24 ÷ [7 + (7-15)]
= 40 - 24 ÷ (7 - 8)
= 40 - 24 ÷ (-1)
= 40 + 24
= 64
On solving the given expression 40 - 24 ÷ {7 + (7 - 15)}, we get 64.
What is function?A function is a relation between a dependent and independent variable. We can write the examples of functions as -
y = f(x) = ax + b
y = f(x, y, z) = ax + by + cz
Given is the function -
40 - 24÷ {7 + (7-15)}
We have -
40 - 24 ÷ {7 + (7 - 15)}
Using the Rule of BODMAS, we can solve the function as -
40 - 24 ÷ {7 + (7 - 15)}
40 - 24 ÷ {7 + (7 - 15)}
40 - 24 ÷ {7 - 8}
40 - 24 ÷ (- 1)
40 - (- 24)
64
Therefore, on solving the given expression 40 - 24 ÷ {7 + (7 - 15)}, we get 64.

Name the minor arc and find its measure.
Answer: Choice B
[tex]\overset\frown{AB} ; \ 115[/tex]
=================================================
Explanation:
The measure of any minor arc is always less than 180 degrees. So it will have a smaller measure than a semicircle. Arc ADB is over 180 degrees, so we can rule that out. Minor arc AB is the measure from A to B following the shorter path along the circle, which would be 115 degrees (the longer path would be 360-115 = 245 degrees)
In other words, the central angle ACB is equal in measure to minor arc AB. Both describe the same basic idea when it comes to circles and their angle measures.

a. 5/12
b. 7/12
c. 1/2
d. 3/5
Answer:
7/12
Step-by-step explanation:
Simple:
There are 12 numbers in all and only 7 even numbers
Since there are 7 even numbers the probability of rolling an even number is 7/12.
This means that there are 7 outcomes of an even number
Therefore the probability of choosing an even number
=7/12

how could you classify the following shape?
A.Quadrilateral
B.Rectangle
C.Rhombus
D.Square
Answer:
Rectangle and Quadrilateral
Step-by-step explanation:
Hi,
It can't be a rhombus because, in a rhombus, all the sides are equal. The same goes for a square so those two aren't correct. It is a rectangle and in a Quadrilateral, the sides are straight. So your two answers are a rectangle and a Quadrilateral.

What function is the inverse of the exponential function y = (1.5)x?
Correct question is;
What function is the inverse of the exponential function y = 1.5^(x)?
Answer:
y = log_1.5_x
Step-by-step explanation:
The inverse of exponential functions is usually written in form of logarithm.
For example inverse of y = p^(x) will be written as; y = log_p_(x)
Similarly applying this same pattern to our exponential function y = 1.5^(x), we have the inverse as;
y = log_1.5_x
A therapist charges $369 office three and $4.50 a minute. Write an equation to find the total cost y, after x,the number of minutes?,
Answer:
Total cost= 369 + 4.5x
x= number of minutes
Step-by-step explanation:
Giving the following information:
Fixed cost= $369
Unitary variable cost per minute= $4.5
To calculate the total cost after x minutes, we need to use the following formula:
Total cost= 369 + 4.5x
x= number of minutes
For example, for 45 minutes:
Total cost= 369 + 4.5*45
Total cost= $571.5
