The smaller triangle is scaled by a factor of (18 cm)/(54 cm) = 1/3 of the larger triangle. The ratio of areas is the square of that scale factor.
small triangle area = (1/3)^2 × large triangle area
... = (1/9) × 603 cm^2
... = 67 cm^2
The appropriate choice is
... C. 67 cm^2
Answer:
The fraction of brownies with both white frosting and small red hearts is not given. And also the total number of brownies made is not given too.
Therefore, the number of brownies that have both white frosting and small red hearts on them cannot be determined
Step-by-step explanation:
Given;
1. You put 1 white frosting per 3 of the brownies
2. You put 1 small red hearts per 4 of the brownies
Fraction of brownies with;
White frosting = 1/3
Small red hearts = 1/4
The fraction of brownies with both white frosting and small red hearts is not given. And also the total number of brownies made is not given too.
Therefore, the number of brownies that have both white frosting and small red hearts on them cannot be determined
For example:
Assuming that;
The fraction of brownies with both white frosting and small red hearts = 1/12
The total number of brownies baked = 36
The number of brownies with both white frosting and small red hearts = 1/12 × 36 = 3 brownies.
Answer:
13 km
Step-by-step explanation:
The area formula for a triangle is ...
A = (1/2)bh
We are told that b=2h, so this becomes ...
A = (1/2)(2h)(h) = h²
Substituting the given area, we can find h:
169 km² = h²
(√169) km = h = 13 km
The height is 13 km.
