Taylor has 27 books in her book collection. She keeps 1 book beside her bed and keeps the remaining books in a bookcase. She can fit up to 8 books on a shelf. What is the least number of shelves Taylor needs for all her books?
Answer:
4 shelves
Step-by-step explanation:
First you will have to subtract the one she keeps by her bed.
27 - 1 = 26 to be put on a shelf.
To find the least number of shelves needed, you will divided the total left by eight:
26 ÷ 8 = 3.25
She can fill 3 shelves completely and still have books left over. So she needs at least 4 shelves!

Answer:
37.5
Step-by-step explanation:
cosФ = \(\frac{A}{H}\)
cos(33°35') = \(\frac{m}{45}\)
m = 45 × cos(33°35')
m = 37.5 (1d.p.)
In triangle ABC, we have AB = 5, BC = 8, and AC = 7, as shown below:
Calculate: cos(angle A), cos(angle B), cos(angle C)
Please don't post any absurd answers, they will be reported
The angles are;
A = 60
B = 38
C = 82
What is the cosine rule?The cosine rule is a mathematical formula used in trigonometry to determine the lengths of sides of a triangle, given the lengths of two sides and the measure of the angle between them. The cosine rule states that the square of the length of a side of a triangle is equal to the sum of the squares of the lengths of the other two sides, minus twice the product of the lengths of those sides and the cosine of the angle between them.
c^2 = a^2 + b^2 - 2abCos C
7^2 = 5^2 + 8^2 - 2(5 *8) Cos C
49 = 25 + 64 - 80 CosC
-40 = -80 CosC
Cos C = 0.5
C = 60°
b^2 = a^2 + c^2 - 2ac Cos B
5^2 = 8^2 + 7^2 - 2(8 *7) Cos B
25 = 64 + 49 - 112Cos B
Cos B = 38
C = 180 - (60 + 38)
A = 82

.02x + .02 = .08 solve for x
Answer:
x = 3Step-by-step explanation:
.02x + .02 = .08 solve for x
0.02x + 0.02 = 0.08
0.02x = 0.08 - 0.02
0.02x = 0.06
x = 0.06 : 0.02
x = 3
----------------
check
0.02 * 3 + 0.02 = 0.08
0.06 = 0.08 - 0.02
0.06 = 0.06
The answer is good

What is the distance traveled by the tip of the second hand of a clock in 1 minute if the hand is 10.5 inches long? Leave your answer in terms of π.
Answer:
(1/30π) x 6 cm = 0.06283185 x 6 cm = 0.376 cm.
Step-by-step explanation:
The distance travelled by the tip of the second hand of a clock in 1 minute, if the hand is 6 cm long, is approximately 3.6 degrees or approximately 0.06283185 radians. This is because the circumference of a complete circle is equal to 2π radians, and a clock face is divided into 60 equal parts, so each part is equal to 1/60 of 2π or 1/30π radians. To convert this to cm, you can multiply by the length of the second hand, which is 6 cm. Therefore, the distance travelled is (1/30π) x 6 cm = 0.06283185 x 6 cm = 0.376 cm.

You pick a card at random, put it back, and then pick another card at random.
6, 7, 8, 9.
What is the probability of picking a 9 and then picking a number greater than 7?
Write your answer as a percentage.
Answer:
12.5%
Step-by-step explanation:
There are 4 cards to choose from in the beginning.
Pick 9 out of the 4.
p(9) = 1/4
You put the card back. Now there are again 4 cards.
There are 2 numbers greater than 7: 8 and 9.
p(8 or 9) = 2/4 = 1/2
p(9 then number greater than 7) = 1/4 × 1/2 = 1/8
1/8 = x/100
8x = 100
x = 100/8
x = 12.5%
