Answer:
The radius is 20 units.
Step-by-step explanation:
(r)^2 + 21^2 = (r+9)^2
r^2 + 441 = r^2 + 18r + 81
360 - 18r = 0
360 = 18r
20 = r

It is Marcie's first turn to roll. Which ratio shows the theoretical probability that she will not land on a star space? 1/6 1/3 1/2 2/3
Answers
Answer:
[tex]P(Not\ Star) =\frac{2}{3}[/tex]
Step-by-step explanation:
Given
See attachment
Required
Theoretical probability that a roll will not land on a star
From the attachment, we have:
[tex]n = 12[/tex] --- Total space
[tex]Star = 4[/tex]
So, the theoretical probability that a roll will land on a star is:
[tex]P(Star) = \frac{n(Star)}{n}[/tex]
[tex]P(Star) = \frac{4}{12}[/tex]
[tex]P(Star) = \frac{1}{3}[/tex]
Using the complement rule, the probability that it will not land on a star is:
[tex]P(Not\ Star) = 1 - P(Star)[/tex]
[tex]P(Not\ Star) = 1 - \frac{1}{3}[/tex]
Take LCM
[tex]P(Not\ Star) =\frac{3-1}{3}[/tex]
[tex]P(Not\ Star) =\frac{2}{3}[/tex]

Step-by-step explanation:
Three paintings are shaped like an 8-foot square a 7-foot by 4-foot rectangle and a triangle with 6-foot base and height of 7 feet. If those paintings are hung together on the outside of the building how much of the building s wall they cover together ?
Answers
Answer:
113 square feet
Step-by-step explanation:
the total area covered can be determined by adding the area of the rectangle, triangle and square together
Area of a square = length² = 8² = 64 ft²
Area of a rectangle = length x width = 7 x 4 = 28 ft²
Area of a triangle = 1/2 x base x height = 1/2 x 6 x 7 = 21 ft²
64 + 28 + 21 = 113 ft²
Kevin has $50 and wants to buy some art paper and paints. One pack of art paper cost $12 and the paints cost $6 per tube. He buys 2 packs of paper. Which inequality should Kevin solve to find the maximum number, n of tubes of paint that he can buy
Answers
Answer:
26 ≤ 6
Step-by-step explanation:
$50 is the budget
Art paper = $12
Paints = $6
He gets 2 packs of paper making it $24
$50 - $24 = $26
26 divided by 6 = 4.33333 (he can only get 4)

My little brother spent $5 on comic books and magazines. He bought 4 items. If comic books
cost $1 and magazines cost $2, how many of each item did my brother buy?
comic books
magazines
No links please!
Thank you
Answers
Answer: He bought 1 magazine and 3 comic books.
Step-by-step explanation: If comic books cost $1 and magazines cost $3, the equation for the problem should look like this: 2(m) + 1(c) = 5, since you know that the brother spent $5 in total. "m" represents the number of magazines purchased while "c" represents the number of comic books purchased. If you plug in 1 for "m" and 3 for "c", the equation would be true and would equal a total of $5. Also, 1 magazine and 3 comic books would mean that the little brother did, in fact, purchase 4 items.
