Answer:

138

Step-by-step explanation:

70 + 32 = 102

102 + 36 = 138

138 + 40 = 178

178 + 44 = 222

If the angle of a sector measures 60°, what fraction of the circle is the sector?
maks197457 [2]

The angle of the sector is also equal to the arc measure of the circle. This is because a sector is made up of two radii of a circle.

A circle is 360 degrees.

60 / 360 = 1/6

The sector is 1/6 of the circle.

Hope this helps!! :)

Blaine is on vacation in New York City and wants to collect magnets of places he visits to give to all his friends. The Times Sq
julsineya [31]

For Times Square magnets, we have that the price of each magnet is 2 dollars / magnet, there are 4 magnets / set, and Tom buys 12 sets. For Statue of Liberty magnets, the price is 3 dollars / magnet, there are 5 magnets / set, and Tom buys 12 sets

We can make a table of these values:

Magnets          Price ($$/magnets)        Set Size (magnets/set)         Quantity (sets)

T.S.                2                                  4                                        12

S. of L.           3                                  5                                        12

Now, we can use the formula

Total Cost = Number of Magnets Bought * Price = (Quantity * Set Size) * Price

So we see that

Cost of T.S. magnets = Quantity * Set Size * Price

                              = 12 sets * 4 magnets * 2 dollars = $96

                                                      set          magnet

Cost of S. of L. magnets = Quantity * Set Size * Price

                                  = 12 sets * 5 magnets * 3 dollars = $180

                                                          set          magnet

So the total amount spent was $96 + $180 = $276.

Sheila was making place-value disks. She colored 2/6 of the disks red. She colored 1/4 of the disks yellow. If she colored 40 re
Anastasy [175]

Answer:

She colored 30 yellow place value disks and 50 disks are left to color.

Step-by-step explanation:

Let total number of disks be x.

It is given that, she colored 2/6 of the disks red. She colored 1/4 of the disks yellow.

\text{Red disks}=\dfrac{2}{6}x

\text{Yellow disks}=\dfrac{1}{4}x

She colored 40 red place value disks.

\dfrac{2}{6}x=40

\dfrac{1}{3}x=40

x=120

It means total number of disks is 120.

\text{Yellow disks}=\dfrac{1}{4}x=\dfrac{1}{4}(120)=30

So, she colored 30 yellow place value disks.

Remaining disks = Total disks - Red disks - Yellow disks

               =120-30-40

               =50

Therefore, 50 disks are left to color.

Use the graph to find the value of y=sin q for the value of q 330​
Otrada [13]

Answer:  A) -0.5

Explanation:

Each tickmark is an increment of 30. Start at 270 and move 1 tickmark over to get to 270+30 = 300. Then another tickmark to the right gets us to 330.

Then from here, head straight down until you get to the curve. You should arrive at the point (330, -0.5)

So q = 330 pairs up with y = -0.5
