A restaurant orders corn tortillas and flour tortillas. The ratio of the number of corn tortillas to the number of flour tortillas is 2 : 3. What is the ratio of the number of flour tortillas to the total number of tortillas?
3 : 8
3 : 5
2 : 8
2 : 5
Answers
Answer:
The answer is 3:5
Step-by-step explanation:
Since the Ratio is to flour tortillas to total, we already know that the number of flour tortillas is 3.
The total number is 5. If you add up both flour tortillas and corn tortillas the total number would be 5.
The ratio would be 3:5
2:3
Flour to total
3:5
You answer is 3:5

Terry is an up-and-coming florist who specializes in weddings. He uses 5 roses, 3 daisies, and 4 bundles of green filler to make one bouquet. If r is the cost of a rose, d is the cost of a daisy, and f is the cost of a bundle of green filler, which expression represents the cost for making 75 bouquets?
75r +75d + 75f + 12
(5r + 3d + 4f) + 75
75(5r) + 75(3d) + 75(4f)
75(5r + 3d + 4f)
Answers
Answer: The last two are right
Step-by-step explanation: 75x5= $375, 75x3=$225, 75x4=$300.
Add all the sums together and you will get the cost of 75 bouquets, which is $900. - NUMBER 3
5+3+4=12, 12x75=$900
Sorry if I'm wrong first time doing this.
Answer:
option (4) is correct. 75( 5r + 3d + 4f ) expression represents the cost for making 75 bouquets.
Step-by-step explanation:
Given: r is the cost of a rose, d is the cost of a daisy, and f is the cost of a bundle of green filler.
Terry uses 5 roses, 3 daisies, and 4 bundles of green filler to make one bouquet.
Thus, cost of one bouquet = cost of each flower used × number of flower used.
Total cost of one bouquet= 5r+3d+4f
Thus, cost for making 75 bouquets = 75 × cost of one bouquet
= 75( 5r + 3d + 4f )
Thus, option (4) is correct. 75( 5r + 3d + 4f ) is the correct expression to represents the cost for making 75 bouquets

Last week, a chocolate shop sold 4 7/8 ounces of white chocolate. It sold 3 times as much milk chocolate as white chocolate. How many ounces of milk chocolate did the shop sell?
Answers
Answer:
3 21/32 oz.
Step-by-step explanation:
4 7/8 = 39/32
39/32 x 2 = 117/32 = 3 21/32 ounces
milk
white ⬜️ (since 3 times of milk chocolate was sold)
hence to find 1 unit, we divide 4 7/8 by 4,
(4 7/8) / 4 = 1 7/32
3 units = 1 7/32 x 3 = 3 21/32
The shop sold 3 21/32 ounces of milk chocolate.
