Answer:
39 ft²
Step-by-step explanation:
Area of a triangle = 1/2bh
Let:
base = b = 4 ft
height = h = 3 ft
Solve for the area of the triangle:
A = 1/2(4)(3)
A = 2 * 3
A = 6 ft²
Area of a rectangle = bh
Let:
base = b = 9 ft
height = h = 5 ft
Solve for the area of the rectangle:
A = (9)(5)
A = 9 * 5
A = 45 ft²
Subtract the area of the triangle from the area of the rectangle:
45 - 6 = 39 ft²
39 ft² is your answer.

So 1 nickle=5 cents
1 quarter=25 sents
q=number of quarters
n=number of nickles so
total is
q+n=20
5n+25q=400 (since 100 cents=1 dollar and 4 dollares=400 cents)
SO THE 2 EQUATIONS WOULD BE
n+q=20
5n+25q=400
so q+n=20
subtract q from both sides
n=20-q
subsitute 20-q for n in the second equation
5(20-q)+25q=400
distribute
100-5q+25q=400
add like terms
100+20q=400
subtract 100 from both sides
20q=300
divide both sides by 20
q=15
thhere are 15 quarters
subsitute 15 for q in first equation
15+n=20
subtract 15 from both sides
n=5
5 nickles
15 quarters
Answer:
The family might share maximum of 700 mins each month.
Step-by-step explanation:
Given:
Total number of minutes used by each member = 175
Number of members in family = 4
We need to find the number of minute family will share each month.
Solution:
Let the number of minute family will share each month be 'x'.
So we know that;
Total number of minute family will share each month should be less than or equal to Total number of minutes used by each member multiplied by Number of members in family
framing in equation form we get;
Hence The family might share maximum of 700 mins each month.
Answer:
2:1
Step-by-step explanation:
well we show ratio by the sign ' : '
ratio of iced tea to lemonade= 12:6
now we reduce it to minimum by dividing it with same number.
12 is divisible by 6
so,
the reduced form is = 2:1
therefore,
ratio of the number of students who want iced tea to the number of students who want lemonade = 2:1.
