find the area of ABCD
trapezoid ABCD ~ trapezoid EFGH
trapezoid ABCD: 20cm
trapezoid EFGH: 5cm
area of EFGH = 40 sq cm
Answers
Answer:
640 cm²
Step-by-step explanation:
The ratio of the area of 2 similar polygons = the ratio of the square of their corresponding lengths
Thus:
Area of Trapezoid ABCD to Area of Trapezoid EFGH = AB² to EF²
Area of Trapezoid ABCD = ? = x
Area of Trapezoid EFGH = 40 cm²
AB = 20 cm
EF = 5 cm
Substitute
x:40 = 20²:5²
x/40 = 400/25
x/40 = 16
Cross multiply
x = 16*40
x = 640
Area of trapezoid ABCD = 640 cm²

The perimeter of a right -angled triangle is 72 cm . Its side are in the ratio 3 : 4: 5.Work out the longest length of the triangle.
Answers
Answer:
The longest length is 30 cm
Step-by-step explanation:
Mathematically, the perimeter of a triangle is simply the sum of the lengths of its three sides
So, what we have to do here is divide the perimeter in the given ratio to get the side lengths
since 5 is the biggest of the numbers in the ratio, it represents the largest length value
so we have this as;
(3 + 4 + 5) = 12
So that would be;
5/12 * 72
= 5 * 6 = 30
Jackson recorded the growth of a plant over 10 weeks. The equation y=0.25x+4 represents the height in inches over the time in weeks. How tall will the plant be after 5 weeks? How tall will it be after 12 weeks? (PLEASE HELP)
Answers
Answer:
5.25 inches after 5 wks
7 inches after 12 wks
Step-by-step explanation:
after 5 weeks: y = .25(5) + 4 which is 5.25 inches
after 12 weeks: y = .25(12) + 4 which is 7 inches

Two functions, A and B, are described as follows: Function A y = 8x + 3 Function B The rate of change is 1 and the y-intercepted is 4. How much more is the rate of change of Function A than the slope of Function B?
Answers
Answer:
7
Step-by-step explanation:
Expressing Both equations in the slope intercept format : y = mx + c
Function A :
y = 8x + 3
Where, slope = 8 ; intercept = 3
Function B:
y = x - 4
Note ;
Rate of change = slope
Rate of change or slope of function A = 8
Slope of function B = 1
Difference = 8 - 1 = 7
Footballs sell for $27.99 each at the Sports R' Us and for $21.59 each at the Fitness Depot. If the coach buys a dozen footballs, how much can he save by buying them at the Fitness Depot?
Answers
Answer:
He can save $76.8 by buying them at the Fitness Depot.
Step-by-step explanation:
If the coach buys a dozen footballs, it means that he buys 12 and first, you need to determine the cost of purchasing the 12 footballs at each store by multiplying the amount of footballs for the price at each store.
-Sports R' Us: $27.99*12=$335.88
-Fitness Depot: $21.59*12=$259.08
Then, you have to find the difference between the total cost at both places:
$335.88-$259.08=$76.8
According to this, the answer is that he can save $76.8 by buying them at the Fitness Depot.

10). m(arc AB) = m(arc BC) = m(arc CA) [given in the picture]
m(arc AB) = [tex]\frac{360^0}{3}[/tex]
= 120°
Therefore, m(arc ACB) = m(arc AC) + m(arc BC)
= 120° + 120°
= 240°
11). m(arc CD) = 127° [Given]
m(arc AB) = 51° [Given]
m(arc AC) = m(arc BD) [Given]
m(arc CD) + m(arc BD) + m(arc AB) + m(arc AC) = 360°
127° + 2[m(arc BD)] + 51° = 360°
178° + 2[m(arc BD)] = 360°
2[m(arc BD)] = 360° - 178°
m(arc BD) = 91°
Since, m(arc CDB) = m(arc CD) + m(arc BD)
Therefore, m(arc CDB) = 127°+ 91°
= 218°
12). m(arc EH) + m(arc ED) + m(arc DH) = 360°
180° + 53° + m(arc DH) =360°
m(arc DH) = 360° - 233°
m(arc DH) = 127°
