Tomas is preparing a grocery budget for his restaurant. he knows that he uses a 10-pound bag of onions in 3 days. a 10-pound bag of onions costs $9.50. which strategies can tomas use to determine his budget for onions in a month with 30 days? a. tomas can use the proportion for the ratios of days to cost, 39.5=30x, to solve for x, the budget needed for onions in 30 days. b. tomas can determine the number of 10 pounds bags of onions needed by multiplying by 30 days, and then using that in a proportion for the ratios of price to pounds, 9.510=x300, to solve for x, the budget needed for onions in 30 days. c. tomas can use addition to determine the price per pound of onions and the number of pounds of onions per day, and then multiply by 30: (9.510+103)30=x. d. tomas can subtract by 3 to find the cost of onions per 1 day, and then multiply by 30 for the monthly cost: (9.5−3)30=x.

Step-by-step explanation:

Tomas knows that he uses a 10-pound bag of onions in 3 days. A 10-pound bag of onions costs $9.50.  Thus, a $9.50 bag lasts 3 days.  We're interested in the onion cost for 30 days, so we multiply numerator and denominator of this rate by 30 days.  We thus obtain:

$9.50 * 30 days

= $95.00

       3 days

Tomas must budget $95 for onions for each 30-day month.

the answer is d

step-by-step explanation:

y+3=-4(x-2)

y+3=-4x+8

y=-4x+5

9) i can't see the angle so whatever it is just do this: cos(angle) x hypotenuse and then use that answer and they hypotenuse and plug it into this: (answer you just got)^2 + b^2 = (hypotenuse)^2. the first answer will be the answer of the adjacent side and the second answer after this equation will be the opposite side.

10) y = 14 x = √147 or 12.12435565

11) x = 4.8

12) x = 4.2

13) x = 9.3

14) pq: 13.2

qr : 17.6

angle p: 53º

15) angle c: 54.3º

angle a: 35.7º

16) h = 21040

v = 1841

step-by-step explanation:

10) 7/sin(30) = 14 = y

7^2 + b^2 = 14^2

49 + b^2 = 196

b^2 = 196 - 49

√b^2 = √147

x = √147

11) cos(70) x 14 = 4.788282007

x = 4.8

12) tan(25) x 9 = 4.196768923

x = 4.2

13) sin(31) x 18 = 9.270685348

x = 9.3

14) pq: sin(37) x 22 = 13.23993051

pq: 13.2

qr: cos(37) x 22 = 17.56998122

qr : 17.6

angle p: 180 - (37 + 90) = 53º

15) cos-1(7/12) = 54.31466529

angle c: 54.3º

angle a: 180 - (90 + 54.31466529) = 35.68533471

angle a: 35.7º

16) 4 x 5280 = 21120

cos(5) x 21120

h = 21039.63202

h = 21040

sin(5) x 21120

v = 1840.729287

v = 1841
