Answer:
2%
Step-by-step explanation:
Given data
Sales = $8,900
Donated amount= $178
Percentage of donated sales= Donated amount/ Sales*100
Percentage of donated sales= 178/ 8900*100
Percentage of donated sales=0.02*100
Percentage of donated sales=2%
Hence the percentage is 2%
Megan's age is three years more than four times her daughter's age. If Megan's daughter's age is $d$ , Megan's age is
Answer: 4d + 3
Step-by-step explanation:
Megan's daughter's age = d
Based on the information given, since Megan's age is three years more than four times her daughter's age, this can be written mathematically as:
= (4 × d) + 3
= 4d + 3
Therefore, Megan's age is 4d + 3.
For example, if the daughters age is 7 years, Megan's age will be:
= 4d + 3
= 4(7) + 3
= 28 + 3
= 31 years
20% of a is 11 what is a
Answer: 20% of 11 is 2.2
Step-by-step explanation:
Answer:
55
Step-by-step explanation:
To solve this set up a proportion. This proportion should be in part/whole form. This means to divide the part (aka 11) by the whole (aka the variable), additionally, 20% can be made into a fraction by dividing it by 100. So the proportion is [tex]\frac{20}{100} =\frac{11}{x}[/tex]. Then, cross multiply. Once this is done the new equation is [tex]20x=1100[/tex]. Next, divide both sides by 20. This gives you [tex]x=55[/tex], therefore 11 is 20% of 55.

350 people watched a beauty contest. Some paid GH¢20.00 each while others paid GH¢30.00 each. The total amount collected was GH¢8,800.00. Find how many paid the two different rates.
Answer: 170 people paid GH¢20 and 180 people paid GH¢30
Step-by-step explanation:
Let the number of people that paid GH¢20 be represented by x.
Let the number of people that paid GH¢30 be represented by y.
Based on the above information given, we can form an equation which will be:
x + y = 350 ....... i
20x + 30y = 8800 ....... ii
Multiply equation i by 20
20x + 20y = 7000 ...... iii
20x + 30y = 8800 ...... iv
Subtract iii from iv
10y = 1800
y = 1800/10
y = 180
Since x + y = 350
x = 350 - y.
x = 350 - 180
x = 170
Therefore, 170 people paid GH¢20 and 180 people paid GH¢30

An altitude is drawn from the vertex of an isosceles triangle, forming a right angle and two congruent triangles. As a result, the altitude cuts the base into two equal segments. The length of the altitude is 26 inches, and the length of the base is 18 inches. Find the triangle's perimeter. Round to the nearest tenth of an inch.
Answer:
if it was 29inches it would be 78.7
Step-by-step explanation:
The given altitude and the base length of the triangle can be used for
finding the lengths of the other two sides.
The perimeter of the triangle is approximately 73.0 inches
Reasons:
The altitude is the perpendicular bisector of the base of the triangle
Length of the altitude = 26 inches
Length of the base of the triangle, b = 18 inches
Required:
The perimeter of the triangle
Solution:
The base length of the two congruent triangles formed are [tex]\dfrac{18 \, cm}{2}[/tex] = 9 cm
each.
Therefore;
The length of the hypotenuse side, L, is given by Pythagoras's theorem as
follows;
L² = 9² + 26² = 757
The hypotenuse side, L = The length of the equal sides of the isosceles triangle
Therefore, the perimeter of the triangle, P = b + 2·L
Which gives;
To the nearest tenth, the perimeter of the triangle, P = 18 + 2·√(757) ≈ 73.0
The perimeter of the triangle, P ≈ 73.0 inches

2) A = 12 in.²
5) A = 737 in.²
6) A = 48 in.²
9) A = 2400 in.²
Step-by-step explanation:
2)
Trapezoid
base1 = 4 in.
base2 = 2 in.
height = 4 in.
A = (b1 + b2)h/2 = (4 + 2)(4)/2 = 12
A = 12 in.²
5)
rectangle + semicircle
A = LW + ½πr²
A = 29 * 20 + ½(3.14)(10²)
A = 580 + 157
A = 737 in.²
6)
A = 8 * 8 - 4 * 4
A = 48 in.²
9)
A = 50 * 60 - 20 * 30
A = 2400 in.²
