Answer: 29

Step-by-step explanation:

[tex]58*\frac{4}{8} =\frac{58*4}{8} =\frac{232}{8} =29[/tex]

We reduce the fraction 4/8 to its lowest expression by extracting and canceling 4.

A Divided Dinner
Kenny is providing dinner to 12 families who need food. Each family is the same

Directions: Fill in the chart with the total amount, in pounds, of each food
item each family will receive

Answers

Answer:

Filling the chart to estimate the amount of each type of food that each family will receive is as follows:

Rounded Food Items and Families:

Food Item Number of Pounds Number of Families Estimated

Rounded Receiving Item Receiving

Chicken rolls 113 10 11.3

Mashed potatoes 7 12 0.6

Corn 28 10 2.8

Green bean 19 11 1.7

Casserole 5 3 1.7

What is an estimate?

An estimate is a rough calculation based on available information or rounded-off data.

Estimates are made to enable quick decisions without knowing complete details.

For this estimate, we used the division operation to obtain the quotients that should be the share of receiving families from each food category.

Original Data:

Food Item Number of Pounds Number of Families

Available Receiving Item

Chicken rolls 113.4 9

Mashed potatoes 6.6 12

Corn 28.5 10

Green bean 18.92 11

Casserole 5.37 3

Thus, as much as possible, some pounds of food items have been rounded to enable the estimate to be produced.

The Complete Table for Rounded Food Items and Families is shown below

What is an estimate?

An estimate is a rough computation made using information that is currently known or data that has been rounded off.

Answers

Answer:

8) 24 meters

9) 50.75 feet

10) 166 meters

Step-by-step explanation:

8) the perimeter is the sum of all sides of your shape. The shape is a rectangle, so you know 2 sides are the same length, 16.3 meters, and the other two sides are the size of the width, that is asked for.
so the perimeter = 2*length + 2*width which gives you the equation
80.6 = 2*16.3 + 2*x
then you solve it this way:
80.6 = 32.6 + 2x  | substract 32.6 on both sides
48 = 2x | divide by 2 on both sides
24 = x
so you know the width is 24 meters

9) again, the perimeter is the sum of all 3 sides of your triangle.
2 sides are each 36 and 3 quarters feet long.
so the equation is perimeter = 2*36 3/4 + unknown side, giving you the equation
124 1/4 = 2 * (36 3/4) + x
124.25 = 73.5 + x | substract 73.5 on both sides
50.75 = x
so the third side is 50.75 feet (or in other writing 50 and 3/4 feet)

10) so on the image you see that the park is a triangle. you are given the area and one side (along Second Ave) and you need to figure out the length of the side along Front Street. When you "double" the triangle, you get a rectangle.
The area of the imagined rectangle is 2 times the area of the triangle (the park), so the area of our rectangle is 13778.
The area of a rectangle is calculated width * length.
This gives you the equation
13778 = 83 * x | divide both sides by 83
166 = x
So the length of the park along Front Street is 166 meters.

A new health drink has ​130% of the recommended daily allowance​ (RDA) for a certain vitamin. The RDA for this vitamin is 20 mg. How many milligrams of the vitamin are in the​ drink?

Answers

Answer: 58.5 milligrams

Step-by-step explanation:

Answer:

58.5 mg

Step-by-step explanation:

Drink: 130% of RDA of vitamin X

RDA vitamin X = 45 mg

130% of 45 = mg in the drink

130% = 130/100 = 1.3

130% of 45 = 1.3 * 45 = 58.5

Thus, this new drink has 58.5 mg of vitamin.

The exotic beauty of fish for these miniature habitats attracts many people to the pastime. One unusual addition is the lionfisha particularly striking species with red-and-white stripes, flowy fins, and a series of long spines down its back. Lionfish are native to the Indo-Pacific region where they are a top predator in the coral reefs of tropical waters. Choosing a lionfish for a saltwater aquarium should be a careful decision, though. Some people purchase this unique fish, and then, when they grow tired of the work needed to maintain an aquarium, set the fish free. This action has been a notably distressing problem off Florida and up the Atlantic Coast. Lionfish are a novel species in this region and other animals are confused by their look and behavior. As a result, smaller fish and invertebrates become easy prey for the lionfish. The total irresponsibility of saltwater fish owners has disturbed the ecological balance in the Atlantic. Therefore, aquarium owners who decide to have lionfish or other saltwater fish species are a main cause for environmental damage in the region. There should be immediate and strict regulation on the aquarium fish industry. Which choice best explains the effect of the authors faulty reasoning?
