vagabundo [1.1K]3 years ago
6 0

1) Assuming that 1 month is 30 days. We would take 30 (# of days in the month) divided by 4, which would be 7.5. So every 7.5 days ( or 1/4 of a month) she will build 1 1/2 simple machines. so 1 1/2 times 4 equals 6. She will build 6 simple machines each month.

3) D. 6 miles, you would take 60 divided by 6 which is 10, divided by 3/5 which is 6.

The table shows the number if votes for the new school mascot. What percent of the students chose a mascot other than Tigers?
eduard
The total votes are 50. If you are finding out the percentage of students that did not choose the Tigers, you would subtract the Tigers votes from the total. 50-14 =36. 36/50 would equal .72, turn that into a percent and you have 72% of students not voting for Tigers.

Please help and can you explain
NISA [10]

Answer:

x = 6

Step-by-step explanation:

first you would put them equal because they have the same angle: 9x + 10 = 2x + 52

subtract 10 from both sides: 9x = 2x + 42

subtract 2x from both sides: 7x = 42

divide by 7 on both sides x = 6

hope this helps! :)

Find volume with full working out thank you ;)
Alina [70]

Answer:

2110 cm³

Step-by-step explanation:

Volume = V1 + V2,

Where V1 is the volume of the pyramid, and V2 is the volume of half cylinder

V1 = ⅓×(Base area)×height

V1 = ⅓×(12.6×21.5)×8.5 = 767.55

V2 = ½×(pi×r²×h)

r = 12.6÷2 = 6.3

V2 = ½×(pi×6.3²×21.5) = 1340.415

Volume = V1 + V2

= 767.55 + 1340.415

= 2107.965

= 2110 cm³ (3 sf)
