Answers

If there are 36 potato plants, and they are in 4 even rows, that means that there is 9 in each column because 9 x 4 is 36. Since 7 of them were eaten by the sheep and the goat, that means that there are 2 leftover in that row that the sheep and goat got to since 9-7 is 2.

#SPJ1

Final answer:

The area of Millie's rectangular label, which measures 5/12 foot by 5/6 foot, is calculated by multiplying the width and length, resulting in 25/72 square feet.

Explanation:

The student is asking about finding the area of a rectangular label that is 5/12 foot wide and 5/6 foot long. To calculate the area of a rectangle, we multiply the width by the length. In this case:

Width = 5/12 footLength = 5/6 foot

Now multiply these two fractions:

Area = Width × Length = (5/12) × (5/6)

To multiply fractions, you multiply the numerators and multiply the denominators:

Area = (5 × 5) / (12 × 6)

Area = 25 / 72 square feet

Therefore, the area of the label is 25/72 square feet.

A geologist visits 60 volcanoes in Alaska and California. 15% of the volcanoes are in California. How many volcanoes did the geologist visit in California and how many are in Alaska?

Answers

To solve this, first find out how many volcanoes were in California. As 15% were in California, you can multiply the total number of volcanoes by the percent IN DECIMAL FORM. To convert it to decimal form, divide it by 100, so 15/100=.15. Now multiply by your total to get the number of volcanoes in California (C), C=60*.15=9 volcanoes in California. To get the volcanoes in Alaska, yous subtract your volcanoes in California from your total, so 60-9=51 volcanoes in Alaska.

Eric says he knows 9/10 is 1/10 less than 10/10 or 1 mile so he is going to subtract 1 mile then I had 1/10 back can he use this method to solve the example problem explain

Answers

He can, if he subtracts the 1/10 from 10/10 or 1 he will have 9/10.. hope it helped

Answer:

Eric can use this method, it's totally correct.

Step-by-step explanation:

According to Eric's opinion, 9/10is 1/10 less than 10/10 or 1 mile.

So, to prove that, he is going to subtract 1 mile and 9/10, to obtain 1/10 back. Let's see if he's right

[tex]1-\frac{9}{10}=\frac{10-9}{10} =\frac{1}{10}[/tex]

You can observe that Eric is actually right, he can subtract 9/10 from 1 mile, and that operation will return 1/10 back.

Therefore, Eric can use this method, it's totally correct.

Select from the drop-down menus to complete the equation, in standard form, that represents the relationship between the number of bags of mulch left to spread, y, and the time, x, Jonathan has spent mulching.

Answers

it shounld be -9x+y=30
Final answer:

The equation that represents the relationship between the number of bags of mulch left to spread, y, and the time, x, Jonathan has spent mulching, is y = -9x + 30.

Explanation:

To find the equation that represents the relationship between the number of bags of mulch left to spread, y, and the time, x, Jonathan has spent mulching, we can use the slope-intercept form of a linear equation, which is y = mx + b, where m is the slope and b is the y-intercept.

First, we can find the slope, m, by using the formula m = (y2 - y1) / (x2 - x1). Using the points (0,30) and (1,21), the slope is (21 - 30) / (1 - 0) = -9.

Next, we can choose one of the points, (0,30), and substitute the values into the equation to find the y-intercept, b. Plugging in x = 0 and y = 30, we get 30 = -9(0) + b, which simplifies to 30 = b.

Therefore, the equation that represents the relationship is y = -9x + 30, in standard form.

450 is 75.2% of what number?

Answers

598.404255319, or 600 rounded. To get the number you would take 450 and divide it by point 752 (.752). 

Approximately, 450 is 75.2% of 598.4042553.

To find the number of which 450 is 75.2%, we can set up the equation:

[tex]\[ 450 = 0.752 \times \text{number} \][/tex]

To isolate the number, we divide both sides by 0.752:

[tex]\[ \text{number} = \frac{450}{0.752} \\\[ \text{number} \approx \frac{450}{0.752} \\\[ \text{number} \approx 598.4042553 \][/tex]

So, approximately, 450 is 75.2% of 598.4042553.

This means that 450 is 75.2% of the number 598.4042553. In other words, if we take 75.2% of 598.4042553, we get 450.

To verify, we can multiply 598.4042553 by 0.752, which should indeed give us 450.

Four teachers bought 10 origami books and 100 packs of oragami paper for their classrooms. They will share the cost of the items equally. How much should each teacher pay?

Answers

They will take the total price and divide it by four. So x will be the price, so the equation will be x/4=total price per person. 
Final answer:

The total cost of the origami materials needs to be divided by four to find out how much each teacher should pay. Without the prices of the materials, we can't calculate the exact amount per teacher.

Explanation:

To determine how much each teacher should pay, we must first calculate the total cost of the 10 origami books and 100 packs of origami paper. However, the question does not specify the costs of these items, so we cannot provide an exact answer without this information. Once the total cost is known, you can evenly divide that cost by the number of teachers, which is four, to find the amount each teacher should pay.

For example, if the 10 origami books and 100 packs of origami paper together cost $200, you would calculate the total cost per teacher like this:

Total Cost: $200Number of Teachers: 4Amount per Teacher: Total Cost ÷ Number of TeachersAmount per Teacher: $200 ÷ 4 = $50

In this scenario, each teacher would pay $50.
