answer is 13
Step-by-step explanation:
Using the BODMAS rule,bracket of division or multiplication, addition or subtraction.
This applies the rule:
therefore,
23- (12+6)+8 ,calculate within bracket first
=23-(18)+8
now remove the bracket,by multiply by the -1
=23-18+8

Answer:
The 8 pack is the better deal.
Step-by-step explanation:
To get the answer you do the following:
Find the price of one pack for each;
1/12*5= $0.42( cost of one pack for the 12 pack part)
1/8*3= $0.38( cost of one pack for the 8 pack part)

Find the number of four-digit numbers which are not divisible by 4?
PLEASE HELP ASAP!!!
Answer:
i dont see the numbers
Step-by-step explanation:
Answer:
6750
Step-by-step explanation:
The first four-digit number divisible by 4 is 1000.
The last four-digit number divisible by 4 is 9996.
Modeling this as an arithmetic sequence, the nth term is:
a = 1000 + 4(n − 1)
So the number of terms is:
9996 = 1000 + 4(n − 1)
8996 = 4(n − 1)
2249 = n − 1
n = 2250
There are 2250 four-digit numbers that are divisible by 4. Since there are a total of 9000 four-digit numbers, that means there are 6750 four-digit numbers that are NOT divisible by 4.

What is the area of the regular hexagon shown below?
Answer:
Area = 2127.1 cm^2 (to the tenth)
Step-by-step explanation:
We may be missing the length of a side at the top of the picture.
However, we are given "a", so the sides of a regular hexagon can be calculated.
The side of a regular hexagon given "a" is
s = 2a/sqrt(3) = 28.61
Perimeter of hexagon
= 6s
Area of hexagon
= a*perimeter/2
= a*6s/2
= 3as
= 3a*2a/sqrt(3)
=2sqrt(3)a^2
= 2*sqrt(3)*24.78^2
= 2127.1 cm^2 (to the tenth)

Pls mark my ans as brainliest If u mark my ans as brainliest u will get 3 extra pointsGiven the regular decagon, what is the measure of each numbered angle? A. m∡1 = 72°; m∡2 = 18°; m∡3 = 36° B. m∡1 = 18°; m∡2 = 36°; m∡3 = 72° C. m∡1 = 36°; m∡2 = 72°; m∡3 = 18° D. m∡1 = 36°; m∡2 = 18°; m∡3 = 72°
Answer:
D. m∡1 = 36°; m∡2 = 18°; m∡3 = 72°
Step-by-step explanation:
The 10 central angles are all the same for the regular decagon, so each is 1/10 of 360°. Angle 1 is 36°.
Angle 2 is half of angle 1, since the altitude shown is an angle bisector. Angle 2 is 18°.
Angle 3 is the complement of angle 2. It is the other acute angle in the triangle that has angle 2 marked. Angle 3 is 72°.
The formula for the area of a circle is A= ar?m where A is the area and r is the radius. The subject of
the formula is A. Rearrange the formula to make r the subject.
Hi there! :)
Answer:
[tex]\sqrt{\frac{A}{\pi } } = r[/tex]
Step-by-step explanation:
Formula for the area of a circle:
[tex]A = \pi r^{2}[/tex]
Rearrange the equation in terms of "r":
Divide 'π' from both sides:
[tex]\frac{A}{\pi } = r^{2}[/tex]
Take the square root of both sides:
[tex]\sqrt{\frac{A}{\pi } } = r[/tex]
Answer:
[tex]r = \sqrt{ \frac{A}{ \pi}}[/tex]
Step-by-step explanation:
[tex]A =\pi r^2 \\Divide\: both \:sides\:of\:the\:equation \\\frac{A}{ \pi} =\frac{ \pi r^2}{ \pi} \\r^2 = \frac{A}{ \pi} \\\sqrt{r^2} =\sqrt{ \frac{A}{ \pi}} \\\\r = \sqrt{ \frac{A}{ \pi}}[/tex]

7. Given the figure, find the desired measurements
Answer:
m∠F = 66°
m∠D = 57°
Step-by-step explanation:
It looks like you have ...
∠D = ∠E = (4x +1)°
∠F = (5x -4)°
The sum of the angles in the triangle is 180°, so we have ...
2(4x +1) +(5x -4) = 180
13x -2 = 180
x = 182/13 = 14
Then the angle measures are ...
∠D = ∠E = (4(14) +1)° = 57°
∠F = (5(14) -4)° = 66°
__
m∠F = 66°
m∠D = 57°

If 6 • 3 = 18, then 4 + 8 = 20. T F → F T T → T F T → T F F → T
Answer:
False.
Step-by-step explanation:
For the statement: "If 6 • 3 = 18, then 4 + 8 = 20.":
6 * 3 = 18
If you added two after multiplying 6 and 3, you would get 20.
(6*3) + 2 = 20
8 + 4 does not equal 20.

Answer:
-22 - 2 = -24
Step-by-step explanation:
The answer space already has the minus sign so we can infer the number line is showing subtraction.
We start from -22 and jump to -24. This number line skip counts by 2 and we only jumped one unit, it means we subtracted by 2.
So we subtracted -22 by 2 and it is equal -24:

Teresita worked part-time for 2 weeks in a pharmacy. During the second week, she worked 13 times the
number of hours that she worked during the first week. If she worked a total of 25 hours during the 2-week
period, how many hours did Teresita work during the second week?
1.8
2.10
3.12
4.15
Option 4 is correct, Teresita worked 15 hours during the second week.
Given that Teresita worked [tex]1\frac{1}{2}[/tex] times the number of hours during the second week.
Therefore, she worked 1.5x hours during the second week.
The total number of hours she worked during the two weeks is given as 25.
So we can set up the equation:
x + 1.5x = 25
Combining like terms, we have:
2.5x = 25
Dividing both sides of the equation by 2.5, we get:
x = 25/2.5
x = 10
Therefore, Teresita worked 10 hours during the first week.
To find the number of hours she worked during the second week, we can substitute this value back into the equation:
1.5x = 1.5 × 10
= 15
Therefore, Teresita worked 15 hours during the second week.
