B. 3637 units2
C. 7267 units2
D. 48470 units2
Answers
Answer:
Step-by-step explanation:
The surface area of a sphere with radius r is given by
S = 4 pi r^2
for a radius of 11 units,
S = 4 pi 11^2 = 484 pi = 1520.5 sq. units
This does not correspond to any of the answers.
Please check question.
Answer:
484\(\pi\)
Step-by-step explanation:
Surface Area of Sphere Formula: 4\(\pi\)r\(r^{2}\)

A. y = 9/4x
B. y = 6/5x
C. y = 3/4x
D. y = 1/4x
Please show work
Answers
Answer:
C. y = 3/4x
Step-by-step explanation:
3 pages = 4 min
4.5 pages = 6 min
Paxton = Joelle×3
3/4 = 0.75 (Joelle reads 0.75 pages in 1 min)
Paxton = 0.75×3
C. y = 3/4x
for example if y=3 and x=4 than
3 = 3/4×4 3 = 0.75×4 (which equals to 3)

Two friends shop for fresh fruit. Elena buys a watermelon for $6.35 and 3 pounds of cherries. Taniy buys a pineapple for $2.15 and 2 pounds of cherries. Use the variable p to
represent the price, in dollars, per pound of cherries. Write and simplify an expression to represent how much more Elena spent.
Answers
The expression that represents how much more Elena spent is $3.2 + p
Step-by-step explanation:
The variable p represents the price, in dollars, per pound of cherries.
Elena buys a watermelon for $ 6.35 and 5 pounds of cherries. So, the price of the cherries bought by Elena will be = 5*p
Then the total amount spent by Elena during her purchase of fresh fruits is:
$6.35 + 5*p
On the other hand, Tania buys a pineapple for $ 3.15 and 4 pounds of cherries. So, the price of the cherries bought by Tania will be 4*p
Therefore, the total amount spent by Tania during her purchase of fresh fruits is:
$3.15 + 4*p
You want to determine an expression to represent how much more Elena spent. That is, you want to determine the difference between the money spent by Elena and the money spent by Tania, which represents how much more Elena spent:
Total amount spent by Elena on fresh fruits - Total amount spent by Tania on fresh fruits
$6.35 + 5*p - ($3.15 + 4*p)
Solving:
$6.35 + 5*p - $3.15 - 4*p
($6.35 - $3.15) + (5*p - 4*p)
$3.2 + p
The expression that represents how much more Elena spent is $3.2 + p

Step-by-step explanation:
ur welcome plz mark brainliest
2/5 t is the probability that the balloon will be either red or blue.
Thus option A is correct.
What is probability?The mathematical discipline known as probability specializes in determining the possibility of an event occurring. Probability, which expresses the probability of a risk, is calculated by dividing the total possible combinations by the frequency of favorable events. Composite reliabilities vary from 0 to 1, with 1 representing certainty and 0 representing hesitation.
The probability of the event will be taken as
The fact that the data of red and blue will have a chance of occurring in the event
The first draw chance would be 20/100 = 1/5
The second draw would be 20/100 = 1/5
P = 20 / 100 + 20 / 100
P = 1/5 + 1/5
P = 2/5
Therefore, option D is the correct option.

Jenny’s mother is 5 years older than twice Jenny's age. The sum of their ages is 62 years. This is represented by the equation x + 2x + 5 = 62, where x is Jenny’s age.
Plug in the values from the set {12, 15, 18, 19} to find the value of x. The value that holds true for the equation is _____ . So, Jenny is _____ years old and her mother is ____ years old.
Answers
Hello !
12 :\(12 + 2 \times 12 + 5 = 41 \ne62\)
15 :\(15 + 2 \times 15 + 5 = 50 \ne62\)
18 :\(18 + 2 \times 18 \ + 5 = 59 \ne62\)
19 :\(19 + 2 \times19 + 5 = 62\)
The value that holds true for the equation is 19. So, Jenny is 19 years old and her mother is 43 years old.

Which figure has exactly one line of symmetry? A rhombus, pentagon, rectangle and triangle are shown. A. Rhombus B. Pentagon C. Rectangle D. Triangle
Answers
Answer: The figure that has exactly one line of symmetry is B. Pentagon.
Step-by-step explanation: A line of symmetry is a line that divides a figure into two congruent halves that are mirror images of each other. A figure can have zero, one, or more lines of symmetry depending on its shape and orientation. To find the lines of symmetry of a figure, we can use a paper folding method or a reflection test. A paper folding method involves folding the figure along a line and checking if the two halves match up exactly. A reflection test involves reflecting the figure over a line and checking if the image coincides with the original figure.
Using either method, we can see that:
A. Rhombus has two lines of symmetry: one diagonal and one vertical.
C. Rectangle has two lines of symmetry: one horizontal and one vertical.
D. Triangle has either zero or three lines of symmetry depending on the type of triangle. An equilateral triangle has three lines of symmetry: one vertical and two bisecting the angles. An isosceles triangle has one line of symmetry: the perpendicular bisector of the base. A scalene triangle has no lines of symmetry.
B. Pentagon has either zero or five lines of symmetry depending on the type of pentagon. A regular pentagon has five lines of symmetry: each passing through a vertex and the midpoint of the opposite side. An irregular pentagon has no lines of symmetry.
Therefore, the only figure that has exactly one line of symmetry is B. Pentagon, but only if it is an isosceles pentagon.
