Answer:
96 cm²
Step-by-step explanation:
The area of a rhombus is usually found as half the product of the diagonals. Here, the lengths of the diagonals are 16 cm and 12 cm, so the area is ...
A = (1/2)(d1)(d2) = (1/2)(16 cm)(12 cm) = 96 cm²
_____
This is one of the area formulas it is useful to keep handy.
_____
Here, the area can also be found as 4 times the area of the marked triangle. That triangle's area is ...
A = (1/2)bh = (1/2)(8 cm)(6 cm) = 24 cm²
Four times that area is the are of the rhombus:
rhombus area = 4 × triangle area = 4 × 24 cm² = 96 cm²
Answer:
x = 7
y = 4
Step-by-step explanation:
y + 12 = 3x - 5
5y - 4 = 3x - 5
So y + 12 = 5y - x
To solve the equation above, y =4
Sub y = 4,
x = 7
Answer:
40=x
Step-by-step explanation:
59x + 32 = 1.39x
32 = 0.8x
40=x
Answer:
See below for answers and explanations
Step-by-step explanation:
A is not a statistical question because there's only a specific value of computers in the lab
B is not a statistical question because there is only one answer, which is 9 letters
C is a statistical question because members can have different favorites (or they find it hard to choose one).
D is not a statistical question because there is only one amount of people that helped out.
E is not a statistical question because each student purchased their own amount of video games and data can be collected for each individual student
I think it’s B might be wrong though
