A circle has an area of 2290.221. What is the radius? (round to the nearest whole number)
Answer: 27
Step-by-step explanation:
use the formula for the area of circle and solve for r: A=pi r^2
2290.221=pir^2 <---divide by pi
729=r^2 <--- square root both sides
27=r

What is sin 45°?
Lol I need help
Answer:
1/ √2
Step-by-step explanation:
Here, we want to get the value of sin 45
Mathematically the sine is the ratio of the opposite to the hypotenuse
The opposite here is 1 while the hypotenuse is
√2
so the value of sin 45 will be;
1/ √2

Solve each proportion for the variable
Answer:
x = -1
Step-by-step explanation:
4/12 can be simplified to 1/3
1 x+2
--- = --------------
3 2x+5
Using cross products
1 ( 2x+5) = 3 (x+2)
Distribute
2x+5 = 3x+6
Subtract 2x from each side
2x+5-2x = 3x+6-2x
5 = x+6
Subtract 6 from each side
5-6 = x+6-6
-1 =x
Answer:
Step-by-step explanation:
Key skills: Proportions, One variable equations, Multiplication, Distribution Property
1) The best approach to this problem is with cross multiplication.
Cross multiplication is where we multiply the numerator of one fraction with the denominator of the other fraction, and the denominator of one fraction with the numerator of the other fraction.
2) Here we would do: 4(2x+5) and 12(x+2)
3) Since this is a proportion --> 4(2x+5) = 12(x+2)
4) Now, we use distribution property to expand both.
4(2x+5) --> 8x+ 20 12(x+2) --> 12x+24
5) With simplifying we can solve for x:
8x+20=12x+24 We then move the 12x to the left side, and the 20 to the right side: 8x-12x=24-20Now we combine like terms: -4x=4Then we divide by -4 on both sides to solve for x. x=-1If you plug in x=-1 back into the equation: 4/12= 1/3
4/12 does equal 1/3 so x= -1 is the right answer.

The first three terms of an arithmetic sequence are as follows. - 7, - 3, 1 Find the next two terms of this sequence
Please help
Answer:
5, 9
Step-by-step explanation:
To obtain the next term in a sequence add the common difference d to the previous term.
d = a₂ - a₁ = - 3 - (- 7) = - 3 + 7 = 4
Thus
a₄ = a₃ + 4 = 1 + 4 = 5
a₅ = a₄ + 4 = 5 + 4 = 9

Solve for a. √a−b+c=3
a=9+b−c
a=3+√b−√c
a=3+b−c
a=9+√b−√c
The required solution of the given expression is a = 9 + b- c. Option A is correct.
The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
Given expression
√a−b+c=3
Squaring both sides,
a - b + c = 9
Rearrange the equation in order of a,
a = 9 + b - c
Thus, the required solution of the given expression is a = 9 + b - c. Option A is correct.

Data were collected on the following variables. Which variable is LEAST likely to be approximated with a normal model?
A) The distribution of heights of tomato plants growing at an agricultural center, where most heights cluster around the center and there are some very short and very tall heights
B) The distribution of times that a certain brand of house paint lasts on a house, where the distribution is symmetric and bell-shaped
C) The distribution of lengths of the trout living in a certain stream, where the distribution is unimodal and clustered around the center, and the left half is a mirror image of the right half
D) The distribution of weights of mold samples growing in a laboratory, where the distribution is symmetric, unimodal, and does not have any outliers
E) The distribution of ages, in years, of all the residents of a town, where the right tail of the distribution is longer than the left
Answer:
E) The distribution of ages, in years, of all the residents of a town, where the right tail of the distribution is longer than the left
Step-by-step explanation:
Because the distribution is described as having a tail on the right that is longer than the left, it is skewed right and not a normal model.

Answer:
70°
Step-by-step explanation:
All triangles' angles are added up to 180°

x = 180 - 110
x = 70
Answer:
[tex]x = 70[/tex]
Step-by-step explanation:
[tex]x = 180 - (30 + 80)[/tex]

[tex]x = 70[/tex]
to be sure
[tex]70 + 80 + 30 { = }^{?} 180[/tex]

Answer:
From narrowest to widest:
1) [tex]8\cdot x^{2} + 2\cdot x +5[/tex]
2) [tex]5\cdot x^{2}-1[/tex]
3) [tex]2\cdot x^{2}+4[/tex]
4) [tex]\frac{2}{5}\cdot x^{2}+3\cdot x -5[/tex]
Step-by-step explanation:
The "width" of the quadratic function is determined by the value of the coefficient associated by the monomial of highest grade, with respect to the primitive of the quadratic function, represented by [tex]y = x^{2}[/tex], whose ruling coefficient is 1. If the ruling coefficient of the quadratic function is greater than one, then the curve becomes narrower at the same time that the coefficient increases. Otherwise, if the ruling coefficient of the quadratic function is greater than zero and less than 1, then the curve becomes wider at the same time that the coefficient approximates to zero.
Based on this considerations, we proceed to list the quadratic functions from the narrowest to widest:
1) [tex]8\cdot x^{2} + 2\cdot x +5[/tex]
2) [tex]5\cdot x^{2}-1[/tex]
3) [tex]2\cdot x^{2}+4[/tex]
4) [tex]\frac{2}{5}\cdot x^{2}+3\cdot x -5[/tex]

What is 42653 rounded to the nearest ten
Answer: 42650
Step-by-step explanation:
The tens place is behind the ones place.
The number in the tens place in 42653 is 5.
So to round to the nearest tens you have to change three to 0 because if the number in the ones place is 5 or more, then the number in the tens place would be 1 higher than it used to be while the number in the ones place turns to 0.
However if the number in the ones place is less than 5, then that's the only thing that changes, the ones place would change into a '0.'
Hope that helped!
42650 is the value of the 426563 when rounded to the nearest ten.
What is place value?The value a digit in a number represents based on where it is in the number is known as place value.
Given, the number 42653 which is rounded to the nearest ten value needs to find. Since,
The one's place is in front of the tens place. In the number 42653, the tens place value is 5. The number three must be changed to 0 in order to round to the next tens because, if the number in the one's place is 5 or greater, the number in the ten's place would be 1 higher than it was previously while the number in the one's place would become 0. The one's place would change to a "0" if the number in the one's place is less than 5, but that is all that changes.
Therefore, When rounded to the nearest ten, 42650 represents the value of 426563.
