Here we can solve this question using Unitary Method . As ;

→ In 17hrs the boat travels 452km

→ In 1hr the boat will travel 452km/17

→ In 9hrs the boat will travel 452/17km * 9 = 239.29km

[tex]\rule{200}4[/tex]

Answer 1b:-

→ A car can travel 156km on 13L gasoline .

→ It will travel 1km on 13/156L of gasoline .

→ It will travel 480km on 13/156*480L = 40L of gasoline .

[tex]\rule{200}4[/tex]

Answer 2a :-

→ A boat can go 180 miles on 60L gasoline.

→ It will go 1mile in 60/180L of gasoline.

→ It will go 306 miles in 60/180*306L = 102L of gasoline .

[tex]\rule{200}4[/tex]

Answer 2b :-

→ On 51L of gasoline a car can go 408km

→ On 1L of gasoline car will go 408/51 km

→ On 11L of gasoline it will go 408/51*11L = 88km

A fish market bought two swordfish at a rate of $12 per pound. The cost of the larger fish was three times as great as the cost of the smaller fish. The total cost of the two fish was threes A fish market bought two swordfish at a rate of $12 per pound. The cost of the larger fish was three times as great as the cost of the smaller fish. The total cost of the two fish was $3696. What's the answer

Answers

Answer:

The larger fish weigh 231 pounds and the smaller fish weigh 77 pounds

Step-by-step explanation:

Here is the complete and correct question:

A fish market bought two swordfish at a rate of $12 per pound. The cost of the larger fish was three times as great as the cost of the smaller fish. The total cost of the two fish was $3,696. How much did each fish weigh?

Step-by-step explanation:

Let the cost of the larger fish be x, and the cost of the smaller fish be y.

From the question,

The cost of the larger fish was three times as great as the cost of the smaller fish, that is

x = 3y

Also, from the question,

The total cost of the two fish was $3,696, that is

x + y = $3,696

Since x = 3y, we can write that

3y + y = $3696

Now, we can determine y

3y + y = $3696

4y = $3696

y = $3696/4

y = $924

Hence, the cost of the smaller fish is $924

From x = 3y; we can determine x

y = $924

∴ x = 3y becomes

x = 3 × $924

x = $2772

Hence, the cost of the larger fish is $2772

Now, to determine how much each fish weigh,

From the question, A fish market bought two swordfish at a rate of $12 per pound

To determine the weight of each fish, we will divide the cost by the rate ($12 per pound)

For the larger fish

Cost = $2772

∴ Weight = $2772 ÷ $12 per pound = 231 pounds

Hence, the larger fish weigh 231 pounds.

For the smaller fish

Cost = $924

∴ Weight = $924÷ $12 per pound = 77 pounds

Hence, the smaller fish weigh 77 pounds.

what is the area of this shape?

Answers

should be 264Here is why I say that.

Width Bottom = 8 sq units

Width Top = 4 sq units

Height right = 9 sq units

Height left = about 13 sq units

Add the width and height to lessen the values.

[tex](8 + 4)\\(9 + 13 )\\8 + 4 = 12\\9 + 13 = 22[/tex]

Third, multiply height times width.

[tex]12 * 22 = 264[/tex]

Therefore, the area of this shape should be 264, according to my logic.

Anna has $2.53. How much money will Anna have left if she buys a bright yellow highlighter and a thin blue marker?

thin green highlighter $0.35
package of crayons $0.61
thin blue marker $0.80
bright yellow highlighter $0.74

Answers

Answer:

$0.99

Step-by-step explanation:

A thin blue marker = $0.80

A bright yellow highlighter = $0.74

First, find the total cost of these two products. Add the costs together:

0.80 + 0.74 = 1.54

Anna has $2.53 in all. Subtract 1.54 from 2.53:

2.53 - 1.54 = $0.99

Anna will have $0.99 left.

~

The answer is $0.99
Just do it like this
2.53 - 0.80 - 0.74 = 0.99 and that’s it
