The sum of four consecutive odd numbers is -72. What are the four numbers?

Step-by-step explanation:
I wish i can help
Answer:
- 15, - 17, - 19, - 21
Step-by-step explanation:
let the 4 consecutive odd numbers be
n , n + 2, n + 4, n + 6 ( that is 2 between each odd number ) , then
n + n + 2 + n + 4 + n + 6 = - 72
4n + 12 = - 72 ( subtract 12 from both sides )
4n = - 84 ( divide both sides by 4 )
n = - 21 , then
n + 2 = - 21 + 2 = - 19
n + 4 = - 21 + 4 = - 17
n + 6 = - 21 + 6 = - 15
The 4 numbers are - 15, - 17, - 19, - 21

Given 3(x+7)=-12, we could do 2 things: we could distribute or divide both sides by 3. It appears that we will divide both sides by 3.
3(x+7)/3=-12/3 Divide 3 on both sides to isolate X by Division P.O.E.
x+7=-4.
Then, x+7-7=-4-7 by Subtraction P.O.E. to isolate X.
X=-11 is your answer

6. AB and BC are both tangents to the circle centre O (left).
If OA = 5 cm and AB = 12 cm calculate:
a) the size of angle OAB,
b) the length OB.
7. If OA is a radius of the circle (below) and PB the tangent to
the circle at A, calculate angle ABO.
Answers
Answer:
a) The size of angle OAB is 90°.
b) The length of O is 13cm.
7. Angle ABO is 28°.
Step-by-step explanation:
A) It is a right angle.
B) Since A is a right angle I can use the Pythagorean Theorem.
[tex]12^{2}+5^{2}=c^{2}[/tex]
144+ 25=[tex]c^{2}[/tex]
[tex]\sqrt{169}=\sqrt x^{2}[/tex]
x=13
7) Since Angle OAB is a right angle and all interior angles of a shape equal 180° I added 90 and 62 and subtracted the sum by 180.
90+62=152
180-152=28

I know that the answer is B, 60. But I need to know how i got to that answer. Please help i am so confused.
Answers
Answer:
You are right
Step-by-step explanation:
So basically find the absolute maximum of the graph that the function creates, the highest peak is the spot with the greatest y-value, in this case is (60, 1600).
The x-value that creates the greatest y is also the x-value of the vertex for that function of yours (since your function has end behavior of both ends down). To find the x-value of the vertex, get the average of the 2 x-intercepts. So (20+100)/2, which is 60.

(picture bellow)
What is the measure of the exterior angle at C?
Enter your answer as the correct value, like this: 42
Answers
Answer:
160
Step-by-step explanation:
5x-10+12x=16x
17x-16x=10
x= 10
exterior angle at C = 16x= 16×10 = 160°
Answer:
exterior ∠C = 160
Step-by-step explanation:
Exterior angle property: Exterior angle equals the sum of opposite interior angles.
∠A + ∠B = exterior ∠C
5x - 10 + 12x = 16x {Combine like terms}
17x - 10 = 16x {Add 10 to both sides}
17x = 16x+ 10 {Subtract 16x form both sides}
17x - 16x = 10
x = 10
exterior ∠C = 16x = 16 * 10 = 160

19. When baking a cake, you have a choice of the following pans:
1. a round cake pan that is 2 inches deep and has a 7-inch diameter
2. a 6 inch × 9-inch rectangular cake pan that is 2 inches deep
Which of these pans has the larger volume? Justify your answer.
Note: Write an essay-like answer, and I will give brainliest and rating.
Answers
The answer is
round cake - 82.42 in²
rectangular cake - 114 in²
Round cake:
d = 7 in
r = d/2 = 7 in / 2 = 3.5 in
h = 2 in
The surface are of a cylinder is:
A = 2πr² + 2πrh
The surface are of the round cake (which is actually a cylindrical cake) excluding the bottom is:
A = 2πr² + 2πrh - πr²
A = πr² + 2πrh
A = 3.14 * 3.5² + 2 * 3.14 * 3.5 * 2
= 38.46 + 43.96
= 82.42 in²
Rectangular cake:
w = 6 in
l = 9 in
h = 2 in
The surface are of a rectangle is:
A = 2wl + 2wh + 2lh
The surface are of the rectangular cake excluding the bottom is:
A = 2wl + 2wh + 2lh - wl
A = wl + 2wh + 2lh
A = 6 * 9 + 2 * 6 * 2 + 2 * 9 * 2
= 54 + 24 + 36
= 114 in²

The five-number summary of a data set is given below.
Minimum: 3 Q1: 12 Median: 15 Q3: 16 Maximum: 20
Which of the following is a true statement about outliers for this distribution?
The distribution’s maximum is an outlier.
The distribution’s minimum is an outlier.
There are no outliers for this distribution.
Distribution outliers cannot be determined.
Answers
Answer:
The distribution's minimum is an outlier.
Step-by-step explanation:
Interquartile range is Q3 - Q1 = 16 - 12 = 4
1.5 * IQR = 1.5*4 = 6
Q1 - 6 = 12 - 6 = 6
Q3 + 6 = 16+6 = 22.
Now 3 is outside the range 6-22 but 20 isn't so 3 is an outlier.
The true statement is;
''The distribution's minimum is an outlier.''
Here,
The five number summary of data set is given as;
Minimum : 3 Q1 : 12 Median : 15 Q3 : 16 Maximum : 20
We have to find the true statement about outliers for this distribution.
What is outliers for data set?
An outlier is called an observation that lie abnormal distance from other values in a random sample from population.
Now,
Interquartile range is given as;
Q₃ - Q₁ = 16 - 12 = 4
1.5 * IQR = 1.5 * 4 = 6
Q₁ - 6 = 12 - 6 = 6
Q₃ + 6 = 16 + 6 = 22.
Hence, 3 is outside the range 6 - 22 but 20 is not.
So 3 is an outlier.
Therefore, The distribution's minimum is an outlier.

help !!!! rectangle pqrs has side lengths of 7 and 3 as shown on the grid below
Answers
Even though you have reflected this triangle, your side length would still be the same. Explanation: Reflection is when you take an object on your coordinate plain and put it somewhere else on the plain. So if side QR is 3 than side Q’R’ would also be 3. Hope this helps!
The length of the segment Q'R' will be 3. The correct option is d.
What is translation?
The process of changing the location of the image on the coordinate system will be known as the translation.
The scale factor is defined as the proportion of the new image's size to that of the previous image.
Dilation is the process of increasing the size of an object while maintaining its shape. Depending on the scale factor, the object's size can be increased or decreased.
Here the rectangle is just reflected not dilated the length of the segment Q'R' will be equal to the segment QR.
Q'R' = QR
Q'R' = 3 units
Therefore, the length of the segment Q'R' will be 3. The correct option is d.
