Answer:
18 rotations.
Step-by-step explanation:
As there are 360 degrees in a circle, by proportion, the time for 1 rotation
= (360/107) * 1
= 3.364 minutes.
So the number of rotations in 1 hour (60 minutes)
= 60 / 3.364
= 17.83
Number of rotations does the pulley make in an hour is 18.
Here,
A pulley rotates through 107° in one minute.
What is rotations?
The action or process of rotating on or as if on an axis or center.
Now,
As there are 360° in a circle, by proportion;
Time for one rotation = (360/107) x 1
= 3.364 minutes
Hence, number of rotations in 1 hour
= 60 / 3.364
= 17.83
So, Number of rotations does the pulley make in an hour is 18.

A 7-pack of tickets to the zoo costs $78.61. What is the unit price?
Answer:
$11.23
Step-by-step explanation:
To find the unit price divide the price by the product. For example, 12 ounces of juice costs $2.45. You divide $2.45 by 12 ounces. The unit price would be $0.20.
I hope this helped you, if it did more than all the other answers that may be on your question, feel free to give me brainliest, I would really appreciate it.
A 7-pack of tickets to the zoo costs $78.61. Therefore, the unit price of ticket to the zoo $11.23.
What is division?The division in mathematics is one kind of operation. In this process, we split the expressions or numbers into same number of parts.
Given that a 7-pack of tickets to the zoo costs $78.61.
To find the unit price;
Cost of one pack of ticket to the zoo = total cost of 7 pack of tickets / number of tickets
Cost of one pack of ticket to the zoo = $78.61 / 7
Cost of one pack of ticket to the zoo = $11.23
Therefore, the unit price of ticket to the zoo $11.23.

Carlo sold his house for P8,000,000. The real-estate agent got a 5% commission from the sales.
From his commission, he has to pay BIR tax and other obligations required for the transfer of ownership
of the property to the buyer. This expense represents 6% of his total commission. How much net
amount will he receive?
Answer:
The net amount received is 7,120,000
Step-by-step explanation:
The computation of the net amount received is shown below:
= Sale value of the house - real agent commission - expenses
= 8,000,000 - 8,000,000 × 5% - 8,000,000 × 6%
= 8,000,000 - 400,000 - 480,000
= 8,000,000 - 880,000
= 7,120,000
Hence, the net amount received is 7,120,000

1. Miranda is braiding her hair. Then she will attach
beads to the braid. She wants of the beads to
be red. If the greatest number of beads that will
fit on the braid is 12, what other fractions could
represent the part of the beads that are red?
Complete question :
Miranda is braiding her hair then she will attach beads to the braids she wants 1/3 of the beads to be red if the greatest number of beads that will fit on the braid is 12 what other fraction could represent the part of the beads that are red?
Answer:
2 / 6
Step-by-step explanation:
Fraction of red beads on braid = 1/3
greatest number of braids = 12
Fraction of red beads = (1 /3) * 12 = 4 red beads
Thus implies that :
When greatest number of braids = 12
fraction of red beads) = (Number of red beads / greatest number of beads)
Fraction = 4 / 12

County Middle School is buying pizza for all of its students. Each pizza has 8 slices. Each student will receive 1 slice. There are 700 students at County Middle School. How many pizzas will the school need to buy?
Answer:
88 at least
Step-by-step explanation:
So, if you need to give each student a slice remainders round up to the nearest whole number. So first you simply divide 700/8 (Students/Pieces of pizza per slice) and get 87.5. Then you round up to 88 since you cannot buy half a pizza (that's weird). You will have 4 extra slices to feed the teachers btw.
A: x/8=3/4
B: 2/5=x/40

sina×tga=1/2, cosa=?
Answer:
cos a = -1.28 and 0.78
Step-by-step explanation:
The question is not properly written. This is the correct question:
If sina×tan(a) = 1/2, find cosa
According to trigonometry identity;
tan a = sina/cosa
sina×tan(a) = sin a * sina/cosa
sin²a/cos a = 1/2
(1-cos²a)/cosa = 1/2
Cross multiply
2(1-cos²a) = cos a
2 - 2 cos²a = cos a
2cos²a + cos a - 2 = 0
Let P = cos a
2P² + P -2 = 0
P = -1 ±√1-4(2(2)/2(2)
P = -1 ±√1+16/4
P = -1 ±√17/4
P = -1±4.12/4
P = -1-4.12/4 and -1+4.12/4
P = -5.12/4 and 3.12/4
P = -1.28 and 0.78
Since P = cos a
Hence cos a = -1.28 and 0.78

find the values of x and y?
Answer:
x = 20
Step-by-step explanation:
I don't see a y in the diagram.
The 3 angles x, 90 and (4x - 10) lie on the line EF and sum to 180°, so
x + 90 + 4x - 10 = 180, that is
5x + 80 = 180 ( subtract 80 from both sides )
5x = 100 ( divide both sides by 5 )
x = 20
