Mary is making a pinata that has a ball-like shape. The pinata has a surface area of
60 square feet. Use the formula for the surface area of a sphere:
S=471?
to find the radius of the pinata in feet.
Answer:
2.19 ft
Step-by-step explanation:
The formula for the surface area of a sphere = 4πr²
Surface area of the sphere = 60 ft²
The formula to find the radius of a sphere
= √A/4π
= √60/4 × π
= 2.19 ft
Therefore, the radius of the pinata = 2.19 ft

Lori solved this multiplication problem.
29 × 31 = 699
However, the mistake Lori made when multiplying is that she didn't
a. regroup the 2 in the tens column.
b. place a 0 in the ones column before multiplying 3 × 9.
c. multiply 3 and 9 correctly.
d. add after multiplying the multiplicand by 1 and 3.
The mistake Lori made when multiplying is that she didn't regroup the 2 in the tens column, which is correct option(A).
What are Arithmetic operations?Arithmetic operations can also be specified by the subtract, divide, and multiply built-in functions.
The operator that perform arithmetic operation are called arithmetic operators .
Lori solved this multiplication problem.
29 × 31 = 699
The mistake Lori made when multiplying is that she didn't
We first construct the extended multiplication.
The result of multiplying 1 × 9 is 9.
The result of multiplying 1 × 2 is 2
After that, we multiply 3 × 9 to get 27. Since 27 is a two-digit number, we must carry the first digit, 2, to the following column.
Then we carry the digit of 2, which is 8, and multiply 3 × 2, which results in 6.
Finally, we get 899 by adding 870 and 29.
Hence, the mistake Lori made when multiplying is that she didn't regroup the 2 in the tens column.

Answer:
a=12
Step-by-step explanation:
We must use SOH, CAH, TOA
SOH= Sin0=opp/hyp
CAH=Cos0=adj/hyp
TOA= Tan0=opp/adj
Since we have opposite and hypotenuse we use Sin ratio, in this case,
sin30°= [tex]\frac{a}{24}[/tex]
[tex]\frac{1}{2}[/tex]=[tex]\frac{a}{24}[/tex] we cross multiply
[tex]\frac{2a}{2}[/tex]=[tex]\frac{24}{2}[/tex]divide both sides by 2 to get a by itself
a=12
Answer:
a = 12
Step-by-step explanation:
To find a, we will use the trigonometric ratio of Sin, since the opposite side of the angle given needs to be found out and the hypotenuse is given;
Sin(30) = [tex]\frac{a}{24}[/tex]
Sin(30) * 24 = a
12 = a

Step-by-step explanation:
y-intercept- (0,-5)
x-intercept ( 1 , 0 ) , ( − [tex]\frac{5}{3}[/tex] ,0)
Answer:
If by 3x2 you meant 3(2), then the y-intercept is 1.
Step-by-step explanation:
We need to start by simplifying the equation.
y = 3(2) + 2x - 5
y = 6 + 2x - 5
y = 2x + 6 - 5
y = 2x + 1
The "2x" part tells us the growth rate, or slope, of the line, and the "+ 1" is the y-intercept.

Which is a number that can be written as a fraction in the form a/b?
Answer:
Step-by-step explanation:
Rational numbers are the type of numbers that can be written in fraction forms (1/b where a and b are integers and b ≠ 0). Rational numbers also include decimals that are repetitive (0.313131313131) and decimals that end (0.25).
The opposite are irrational numbers that cannot be written in fraction forms and that include decimals that do not end or repeat (0.249654296432926....).
It is good to know a fraction with denomination equal to zero will give an undefined value.

Which group -15 belongs to
Answer:
Integers.
Step-by-step explanation:
I'm assuming you are talking about number groups, such as integers, natural numbers, whole numbers, etc.
If so, then -15 belongs to the 'integers' group.
This is because consists of numbers that are not fractional components, such as -5, 5, 4, -4, -15, 15, 8, 91, 200, -200, etc. Basically, integers include only negative and positive numbers.
Natural numbers include positive integers only, such as 5, 15, 87, 100, 20, etc.
Whole numbers do not include negative numbers, fractions, or decimals. Examples of whole numbers include: 8, 16, 20, etc.
Therefore, -15 belongs to integers.

Answer:
(2, -3), (3, -3)
Step-by-step explanation:
y = x^2 - 5x + 3
y = -3
x^2 - 5x + 3 = -3
x^2 - 5x + 6 = 0
(x - 3)(x - 2) = 0
x - 3 = 0 or x - 2 = 0
x = 3 or x = 2
We are given y = -3.

One is asked to find what values of the parameter (x) will yield the result (f(x)=-3) if the function (f(x)) is the following,
[tex]f(x)=x^2-5x+3[/tex]
Set this equation up, and solve to find the value of (x) that satisfies this requirement:
[tex]f(x)=x^2-5x+3=-3[/tex]
Inverse operations,
[tex]x^2-5x+6=0[/tex]
Factor, rewrite the quadratic equation as the product of two linear equations,
[tex](x-2)(x-3)=0[/tex]
Therefore the solutions are the following, the (x-coordinate) represents the input, and the (y-coordinate) represents the output.

Answer:
the slope = -2
Answer:
-2
Step-by-step explanation:
The box plot shows the algebra scores of students in class A and class B.
The median score of class A is _____.
The interquartile range of class B is ____.
The difference of the medians of class A and class B is
the interquartile range of either data set.
Answer:
[tex]Mid(A) = 73[/tex]
[tex]IQR(B) = 8[/tex]
The difference of the medians of class A and class B is between the interquartile range of either data set.
Step-by-step explanation:
Given
The attached box plots
To answer this, see attached image for how to read a box plot
With reference to the attached image of how to read the box plot;
Solving (a): The median of class A
[tex]Mid(A) = 73[/tex]
Solving (b): IQR of class B
IQR is calculated as:
[tex]IQR =Q_3 - Q_1[/tex]
From the box plot of class B, we have:
[tex]Q_3 = 87[/tex]
[tex]Q_1 = 79[/tex]
So, we have:
[tex]IQR(B) = 87 - 79[/tex]
[tex]IQR(B) = 8[/tex]
Solving (c):
[tex]Mid(A) = 73[/tex]
[tex]Mid(B) = 82[/tex]
[tex]IQR(B) = 8[/tex]
IQR of class A is calculated as:
[tex]IQR =Q_3 - Q_1[/tex]
From the box plot of class A, we have:
[tex]Q_3 = 76[/tex]
[tex]Q_1 = 68[/tex]
So, we have:
[tex]IQR(A) = 78 - 68[/tex]
[tex]IQR(A) = 10[/tex]
The difference (d) between the medians is:
[tex]d =Mid(B) - Mid(A)[/tex]
[tex]d = 82 - 73[/tex]
[tex]d = 9[/tex]
From [tex]smallest[/tex] to [tex]largest[/tex], we have: 8, 9, 10
i.e. IQR(B), d, IQR(A)
