So we add all the amounts together:

250 + 310 + 275 + 195 = 1030

Then we divide by 4 to find the average.

1030/4 = 257.5

The answer is D: $257.50

Hope that helps!

Answer: No. Equations even if it is paired. So on. It can only have one solution. Although this is only for a system of equations.

A linear can have two. It just depends on what the problem is.

How to do this question plz answer my question

Degger [83]

Answer:

$121.82

Step-by-step explanation:

Okay, this is kind of complex, so let's go step by step.

First, we want to find the area of the rectangular lawn - we can do this by multiplying the length and width. The length is 100 and the width is 45 so $45\cdot100=4500$ m² is the area of the rectangle.

However, there are 3 ponds in which the grass seeds will not be going - so we need to find the area of all 3 of these circles and subtract it from 4500 (our rectangle area).

The area of a circle is represented by the formula $\pi r^2$

The diameters are given here, which is double the radius, so to find the radius of each circle let's divide the diameters by 2.

First circle's radius: $20\div2=10$

Second circle's radius: $10\div2=5$

Third circle's radius: $5\div2=2.5$

Now let's find the area of each circle.

First Circle: $\pi \cdot10^2 = \pi\cdot100=3.14\cdot100=314$

Second Circle: $\pi\cdot5^2 = \pi \cdot25 = 3.14\cdot25=78.5$

Third Circle: $\pi \cdot 2.5^2 = \pi \cdot6.25 = 3.14\cdot6.25=19.625$

Adding all of these values gets us 412.125.

Now we can subtract from this from 4500 to get us 4087.875

If the grass seeds that cost £1.49 cover 50m² each, then we need $4087.875\div50=81.7575$ bags.

Each bag costs £1.49, so the total cost is $81.7575\cdot1.49\approx121.82$

Hope this helped!!

A group of teenagers was asked where they prefer to study and do homework. Their results are shown in the table below. Place Num

Trava [24]

Answer:

C). Circle Graph

Step-by-step explanation:

As per the question, a 'circle graph' would be most adequate to display that the majority of the teenagers prefer to do their study and homework in their bedrooms. A circle graph or pie-chart represents the data in a visually appealing manner using colors to display various proportions of the data that makes it easy to understand for the readers. Thus, more than half of the circle filled with the same color will clearly hint that most of the teenagers love doing their studies in their bedroom. Thus, option C is the correct answer.
