Answer:

a. The area of the garden is 11.68 $m^{2}$

b. $192 and then $177

Step-by-step explanation:

a. 7.5-2.6 = 4.9, so the rectangular part is 4.9 x 1.3 = 6.37

then $\pi r^{2}$ is the area of a circle, but the 2 ends together are 1/2 the circle

so $\pi *1.3^{2}$ = 5.31, The area of the garden is 11.68 $m^{2}$

b. 11.68/.75=15.57, so you have to buy 16 bags (can't buy a partial bag)

16*$12=$192, then 5($33)+$12=$177

A six sided number cube is rolled twice what is the probability that the first roll is an even number and the second roll is a n

sp2606 [1]

Answer:

50% of rolling an even number.

33.33% of rolling a number greater than 4.

Step-by-step explanation:

<h2><em>Even Number Probability: </em></h2>

There're three possibilities to roll an even number: 2, 4, and 6. If it's a six sided dice, there're a total of six rolling possibilities, so the ratio is 3:6, 1:2, or 50% chance of rolling an even number.

<h2><em>Greater Than Four Probability:</em></h2>

There're only two number greater than four on a traditional six sided dice: 5 and 6. There're, again, six sides on a six sided dice, so the ratio of rolling a number greater than four is 2:6, 1:3, or 33.33%.

If you have 3/12 of an orange, how many fourths do you have?

Mrac [35]

Answer:

Answer: one fourth

Fourth is a word that used to describe a number value of 1/4. To answer this question, you need to change the number you got (3/12) into x/4 form. To convert 12 into 4, then you need to divide the numerator and denominator with 3. The equation would be (3/3)/(12/3)= 1/4.

To determine how much fourth the number has, you need to divide the result with 1/4. The calculation would be: (1/4)/ (1/4)= one fourth

hope its help

thank you

What is the area of the 50ft by 100ft yard?

mario62 [17]

Answer: 4410 $ft^2$

Step-by-step explanation:

To find the area of a square or rectangle, all you need to do is multiply the length times the width:

L × W = A

The lengh is 100, and the width is 50

100 × 50 = 5000

However, in this problem, we also have other shapes in the rectangle. To find the area of JUST the green, we need to subtract the areas of the two circles and small blue rectangle.

First, let's get the two circles over with. To find the area of a circle, use this formula:

A = π $r^2$ r is the radius, which in this case, is 6

A = π $6^2$

A = 113 This isn't the exact answer, the exact answer would be 113.0973...

Now let's multiply the area of one of those circles by 2, since we have 2 circles:

113 × 2 = 226

Finally, we have to find the area of the blue rectangle. This is simple, just use the formula from the very beginning:

26 × 14 = 364

The last thing to do is to subtract the areas of the two circles and blue rectangle from the area of the entire thing:

5000 - (226 + 364) = 4410 $ft^2$
