Step-by-step explanation:
We are to determine which numbers is 90 divisible by:
[tex]2,3,4,5,6,9,10[/tex]
For this, we can use the divisibility rule which helps us find out whether a number is exactly divisible by other numbers (i.e. there is no remainder left).
Divisible by 2:
90 is divisible by 2 since it ends with a 0.
Divisible by 3:
90 is divisible by 3 because 90 is a multiple pf 3.
Divisible by 4:
90 is not divisible by 4 because the last two digits are not a multiple of 4
or the last two digits are not 00.
Divisible by 5:
90 is divisible by 5 since it ends with a 0.
Divisible by 6:
90 is divisible by 6 because it is divisible by 3.
Divisible by 9:
90 is divisible by 9 because it is a multiple of 9.
Divisible by 10:
90 is divisible by 10 since the last digit is 0.

a box of cereal contains 15 ounces of cereal there are 9 servings of cereal in the box each serving of cereal has 140 calories which expression could you use to find the number of calories in 1 ounce of cereal
A 140 - 15 * 9
B 15 * 140 / 9
C (9 * 140) / 15
D 15 * 9 / 140
Answer:
(9 * 140) / 15
Step-by-step explanation:
For each serving it is 140 calories, and there is 9 servings in that cereal. So you want to multiply 9 by 140. And there are 15 ounces in the box so the amount of total calories are to be divided by 15. Thus C should be the right answer.
what is 2x-9y=14 need immediate help
Let's solve for x.
2x−9y=14
Step 1: Add 9y to both sides.
2x−9y+9y=14+9y
2x=9y+14
Step 2: Divide both sides by 2.
2x /2
= 9y+14 /2
x= 9 /2 y+7
We need to solve for x.
2x - 9y = 14
Move the 9y to the right side and use inverse operations.
2x = 14 + 9y
Divide both sides of the equation by 2.
x = 7 + 9/2y or x = 7 + 4.5y

In right triangle PQR, if sinP=5/13, then tanP=
5/12
12/13
12/5
Answer:
A
Step-by-step explanation:
Given sinP = [tex]\frac{5}{13}[/tex] = [tex]\frac{opposite}{hypotenuse}[/tex]
Then the right triangle has a hypotenuse of 13 and a leg 5
Use Pythagoras' identity to find the other leg x ( adjacent)
x² + 5² = 13²
x² + 25 = 169 ( subtract 25 from both sides )
x² = 144 ( take the square root of both sides )
x = [tex]\sqrt{144}[/tex] = 12 , hence
tanP = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{5}{12}[/tex]
The value of the tanP when sin is equal to 5/13 is 5/12.
We have given that,
[tex]sinP = \frac{5}{13}[/tex]
What is the formula for the sin ratio?[tex]sin(\theta)=\frac{Opposite}{hypogenous}[/tex]
Then the right triangle has a hypotenuse of 13 and a leg of 5
Use Pythagoras' identity to find the other leg x ( adjacent)
x² + 5² = 13²
x² + 25 = 169 ( subtract 25 from both sides )
x² = 144 ( take the square root of both sides )
taking square root on both sides
[tex]x=\sqrt{144} \\x=12[/tex]
Therefore we get the value of the tanP.
[tex]tanP = \frac{opposite }{adjucent} = \frac{5}{12}[/tex]
Therefore the value of the tanP is 5/12.

If l ll m, what is the value of x?
Answer:
x = 137
Step-by-step explanation:
∠43° and ∠x° are same side exterior angles as they are on the same side as the transversal but outside the parallel lines. The 2 angles are supplementary, hence
x + 43 = 180 ( subtract 43 from both sides )
x = 137
Based on the information given, the value of x will be 137°.
It should be noted that angles x and 43° are on the same side of the transversal but they're are outside the parallel lines. In this case, the angles are supplementary which means that when they are added together, their total angles equal 180°.
Therefore, the value of angle x will be:
= 180° - 43°
= 137°
Therefore, x is 137°.

Question 4) 8.6
Step-by-step explanation:
Mean absolute deviation is the average distance between the data points from the set to the mean point of the data set. It shows the variability in data or how much the data points are spread.
method to calculate Mean absolute deviation:
a. calculate mean
b. calculate absolute deviation of each data point
c. add all the deviations
d. divide absolute deviation by number of points
mean absolute deviation = ∑l[tex]x_{i}[/tex]-xl / n
The given problem has four sub-parts
Solution 1:
Mean= (78+99+90+80+55+56+102+88+60+42)/10
= 750/10
= 75
Mean absolute deviation= ( I 78-75 I + I 99-75 I+I 90-75 I + I 80-75 I +
I 55-75 I + I 56-75 I + I 102-75 I + I 88- 75 I +
I 60-75 I + I 42-75 I) /10
= (174)/10
= 17.4
Solution 2:
Mean = (10+13+7+12+9+8+12+10+11+13)/10
= (105)/10
= 10.5
Mean absolute deviation = ( I 10-10.5 I + I 13-10.5 I + I 7-10.5 I + I 12-10.5 I +
I 9-10.5 I + I 8-10.5 I + I 12-10.5 I + I 10-10.5 I +
I 11-10.5 I + I 3-10.5 I) /10
= 17/10
= 1.7
Solution 3:
Mean= (1+7+10+5+3+3+6+12+9+4)/10
= 60/10
= 6
Mean absolute deviation = ( I 1-6 I + I 7-6 I + I 10-6 I + I 5-6 I + I 3-6 I +
I 3-6 I + I 6-6 I + I 12- 6 I + I 9-6 I + I 4-6 I) /10
= (28)/10
= 2.8
Solution 4:
Mean= (30+46+25+45+18+25+15+32+40+24)/10
= 300/10
= 30
Mean absolute deviation = ( I 30-30 I + I 46-30 I + I 25-30 I + I 45-30 I +
I 18-30 I + I 25-30 I + I 15-30 I + I 32-30 I +

A bank is offering a loan to account holders. If they pay the full amount off in 14 months they are charged no interest. Denise needs a $6500 loan to get a new car, in order for her to avoid interest charge how much will she have to pay back each month?
Final answer:
Denise will need to pay $464.29 each month for 14 months to repay a $6500 loan and avoid any interest charge.
Explanation:
To calculate how much Denise will need to pay each month to avoid an interest charge on her $6500 loan, we simply divide the total loan amount by the number of months she has to repay the loan.
So, the monthly payment Denise needs to make is $6500 divided by 14 months:
$6500 ÷ 14 months = $464.29 per month (rounded to two decimal places).
To repay the full amount in 14 months and avoid any interest, Denise will need to pay $464.29 each month.

i tried working this out but it doesnt make sense, at least the table doesnt... did you make this question up or get it off of a school assignment??
Answer: Option A; 19
Step-by-step explanation:
The data is:
We have 40 students.
16 play football
9 play basketball
4 play bot sports.
We want to find the number of students that do not play either sport, for this we should add the number of students that play football and the number of students that play basketball, subtracting the number of students that play both sports (because we sill be counting those two times, this is because those 4 students are included in the 16 for football and also in the 9 for basketball.)
N = 16 + 9 - 4 = 12 + 9 = 21
the number of students that do not play basket or football is equal to:
40 - N = 40 - 21 = 19
The correct option is A

A- a regular heptagon
B- an irregular convex heptagon
C-an irregular concave heptagon
D- a complex heptagon
Answer:
C. an irregular concave heptagon
Explanation:
Before we begin, we should define the terms used in the choices given:
1- Heptagon: It is the polygon that has 7 sides
2- Regular heptagon: It is a 7-sided polygon in which all sides are equal and all angles are equal
3- Irregular heptagon: It is a 7-sided polygon in which neither the sides nor the angles are equal
4- Concave heptagon: It is a 7-sided polygon in which one or more of its angles are more than 180°
5- Convex heptagon: It is a 7-sided polygon in which all its angles are less than 180°
6- Complex heptagon: It is a 7-sided polygon whose dimensions are in the complex plane
Now, let's check the given diagram:
It is a 7-sided polygon, therefore, it is a heptagon
It's sides as well as its angles are not equal, therefore, it is an irregular heptagon
It has interior angles measuring more than 180°, therefore, it is a concave heptagon
Its dimensions are not in the complex plane, therefore, it is not a complex polygon
Based on the above, the best choice is:
C. an irregular concave heptagon
Hope this helps :)
A heptagon is a seven-sided polygon. Regular heptagons have all equal sides and angles, irregular convex heptagons have unequal sides but all angles less than 180 degrees, irregular concave heptagons have at least one interior angle more than 180 degrees while complex heptagons have intersecting sides.
Explanation:In mathematics, a heptagon is a seven-sided polygon. A- A regular heptagon is a heptagon in which all seven sides and all seven angles are congruent, meaning they are of equal length or degree. B- An irregular convex heptagon has seven sides, but they are not all equal, however, all its interior angles are less than 180 degrees. C- An irregular concave heptagon is also an irregular heptagon, but at least one of its interior angles is more than 180 degrees. D- A complex heptagon is a heptagon with sides that intersect each other, but this is not a standard classification in geometry.

A school typically sells 500 yearbooks in a year for $50 each. The economics class does a project and discovers that they can sell 125 more yearbooks for every $5 decrease in price. The revenue for year book sales is r(x)+(500+125x)(50-5x). To maximize profit, what prices should the school charge for the yearbooks?
Answer:
875 yearbooks.
Step-by-step explanation:
To maximize profit, at $8125 prices should the school charge for the yearbooks
Simplify first the equation,
R(x) = 25000 - 2500x + 6250x - 625x²
Then, we differentiate the equation and equate to zero.
dR(x) = -2500 + 6250 - 1250x = 0
The value of x from the equation is 3.
(1) The price is equal to 50 - 5(3) = $35.
(2) The possible maximum revenue:
R(x) = 2500 - 2500(3) + 6250(3) - 625(3²) = $8125
(3) number of yearbooks sold:
