Jasper's lawn is 3/4 of an acre in size. The fertilizer bag states that 5 1/2 bags are required for 1 acre. How many bags does J

Nady [450]

Answer: $4\dfrac{1}{8}\ \text{bags}$

Step-by-step explanation:

Given

Jasper lawn is three-fourth of an acre

1 acre of land requires $5\frac{1}{2}$ bags

convert mixed numeral to fraction

$\Rightarrow 5\dfrac{1}{2}=\dfrac{11}{2}$

$\therefore 1\ \text{acre}\equiv\dfrac{11}{2}\ \text{bags}\\\\\Rightarrow \dfrac{3}{4}\ \text{acre}\equiv \dfrac{11}{2}\times \dfrac{3}{4}=\dfrac{33}{8}\ \text{bags}$

$\Rightarrow \dfrac{33}{8}\ \text{bags}=4\dfrac{1}{8}\ \text{bags}$

Help me with steps . Thanks

fgiga [73]

Answer:

135 square centimeters.

Step-by-step explanation:

The area of a triangle is given by the formula:

$A=\frac{1}{2}bh$

Where b is the base length and h is the length of the vertical height.

From the triangle, we can see that the base is 18 and the vertical height is 15. Thus:

$A=\frac{1}{2}(18)(15)$

Multiply:

$A=(9)(15)\\A=135\text{ cm}^2$

The area of the triangle is 135 square centimeters.

What is 3/4 - 5/7 ?

AveGali [126]

The solution of $\frac{3}{4} - \frac{5}{7}$ is $\frac{1}{28} \text{ or } 0.0357$

Solution:

Given that we have to find the solution of $\frac{3}{4} - \frac{5}{7}$

To solve the given sum, first make the denominators of both the fractions same

This can be done by taking L.C.M of both denominators

Step 1:

L.C.M of 4 and 7:

The prime factor of 4 = 2 x 2

The prime factor of 7 = 7

For each prime factor, find where it occurs most often as a factor and write it that many times in a new list.

The new superset list is

2, 2, 7

Multiply these factors together to find the LCM

LCM = 2 x 2 x 7 = 28

Thus L.C.M of denominators is 28

Step 2:

Solution of $\frac{3}{4} - \frac{5}{7}$

Multiply the denominator by a number to get 28 and multiply that same number with numerator also

$\frac{3}{4} - \frac{5}{7} = \frac{3 \times 7}{4 \times 7} - \frac{5 \times 4}{7 \times 4}=\frac{21}{28} - \frac{20}{28}\\\\\frac{21}{28} - \frac{20}{28} = \frac{21-20}{28} = \frac{1}{28}\\\\\frac{1}{28} = 0.0357$

Thus solution of $\frac{3}{4} - \frac{5}{7}$ is $\frac{1}{28} \text{ or } 0.0357$

Are the 3 points of a triangle collinear? If not why?

vampirchik [111]

Explanation:

NO, because, collinear means 'points on the same line'

all 3 points of a triangle are not on the same line. They are 3 different points. Therefore, they are not collinear.
