Answer:
she has 2 dollars to spend on thursday for question 3
Step-by-step explanation:
Let the number of weeks to have same amount = x Then:-
1200 + 40x = 700 + 50x
1200 - 700 = 50x - 40x
10x = 500
x = 50
answer is 50 weeks
Answer : 58 square units.
Tip : break the shape down into shapes you can easily find the area of.
I found the area of the two squares on the bottom
They are identical and are both 2 units tall and two units long giving, giving an area of 4, and since there are two of them you can multiply the are by two giving you 8
Next found the area of the remaining shape which is just a rectangle that excludes the two bottom squares which is 10 units long and 5 units tall multiplying to 50
50+8=58
Answer:
6√24 or 29.39metres
Step-by-step explanation:
Area of a triangle is bh/2
The perimeter of an equilateral triangle is 3b
This equilateral triangle can be imagined as two adjoining 30-60-90 triangles. Together, their area is the given 24√3 m²
The base of the individual triangle is √24. The height is √24√3. <em>Multiplying</em><em> </em><em>those</em><em> </em><em>factors</em><em>,</em><em> </em><em>we </em><em>get</em><em> </em><em>the </em><em>given</em><em> </em><em>area,</em><em> </em><em>a </em><em>proof</em><em> </em><em>of </em><em>sorts,</em><em> </em><em>but </em><em>mure </em><em>importantly</em><em>,</em><em><u> </u></em><em><u>we </u></em><em><u>can </u></em><em><u>calculate</u></em><em><u> </u></em><em><u>the </u></em><em><u>length</u></em><em><u> of</u></em><em><u> </u></em><em><u>the </u></em><em><u>hypotenuse</u></em><em><u> </u></em><em><u>as </u></em><em><u>2</u></em><em><u>√</u></em><em><u>2</u></em><em><u>4</u></em><em><u>.</u></em>
sin(30°) = 0.5
√24/(0.5) = 2√24
That is the length of the side of the original equilateral triangle.
The perimeter is 3 times the length of the side:
(3)(2√24) = P
6√24 meters is the perimeter.
