The manager of a garden store decides to hold a Buy 3, Get 1 Free sale on vegetable plants. The sale is held for one week and a total of 636
vegetable plants were sold (not including the ones given away for free). If each plant cost the store $2.90, how much money did the store lose
by giving away the free plants?
Answers
Answer:
the shop lost $922.20 by giving away free vegetable plants.
Step-by-step explanation:
you would start by dividing 636 by two to see how many free vegetable plants were given away.
636 / 2 = 318
this shows us how many free vegetable plants were given for free, so then to find how much money the store lost giving them away for free, you would multiply 318 by 2.9
318 x 2.9 = 922.2
Therefore the shop lost $922.20 by giving away free vegetable plants.

A. 2.59 joules
B. 3.88 joules
C. 38.82 joules
D. 150.00 joules
Answers
Answer:
C
Step-by-step explanation:
i think
The required work done is 38.82 joules.
Work done to be determine for force of 10 newton on angle of 75° for 15 meters.
Work done is define as the force required to move an object by some displacement.
Here, work done = force x displacement x cosФ
= 10 x 15 x cos75°
= 150 x 0.25
= 38.82 joules
Thus, the required work done is 38.82 joules.

How do you divide mixed fractions
Answers
Answer:
See my explanation below.
Step-by-step explanation:
Let's start with two random mixed numbers.
[tex]4\frac{3}{5}[/tex] ÷ [tex]5\frac{1}{4}[/tex]
The first step is starting with [tex]4\frac{3}{5}[/tex]. Think about going from the denominator to the number on the left. After you remember that rule multiply 4 by 5. You should get 20. After that, you add by the numerator. 20 + 3=23
This is how it would be written.
[tex]\frac{23}{5}[/tex]
Do the same for the next mixed number. 5 x 4 = 20 and add by the numerator 21.
[tex]\frac{21}{4}[/tex]
After this is done. You will multiply by those fractions. [tex]\frac{23}{5}[/tex] x [tex]\frac{21}{4}[/tex] = [tex]\frac{483}{20}[/tex] we would write it as [tex]24\frac{3}{20}[/tex] as a mixed fraction.

the diagram shows a right-angle triangle.
Answers
Answer:
Step-by-step explanation
The shortest length of the right-angled triangle is 4 cm.
What is a right-angle triangle?A right-angled triangle is a triangle, that has one of its interior angles equal to 90 degrees or anyone angles is a right angle.
Given is, the diagram shows a right-angle triangle.
We have area of the right-angle triangle = 18 cm²
We know that area of a right-angle triangle = 1/2(base)(height)
18 = 1/2(x - 1)(x + 4)
36 = (x - 1)(x + 4)
x² + 4x - x - 4 = 36
x² + 3x - 4 = 36
x² + 3x - 4 - 36 = 0
x² + 3x - 40 = 0
x² - 5x + 8x - 40 = 0
x(x - 5) + 8(x - 5) = 0
x + 8)(x - 5) = 0
x = -8 or 5
we can only use positive numbers because length can't be negative,
Thus, x = 5
The shortest side is definitely one of the 2 legs. The hypotenuse of a triangle is the longest side.
Therefore,
height = x - 1 = 5 - 1 = 4 cm
base = x + 4 = 5 + 4 = 9 cm
Hence, the shortest length of the right-angled triangle is 4 cm.
