Answer
A
Step-by-step explanation:
So in the diagrams we see there is 2/3 shaded into a 12 cutted square. So we multiply 4x3 to get 12. So now we have to turn the 3 into 12.
so
x
=
Since we multiplied 4 on the bottom we have to multiply 4 on the top.
sorry im not good at explaining but if you need me to re explain ill work on it. :)
Answer:
864 cards
Step-by-step explanation:
72 cards per set times 15 sets = 1080 cards - 216 cards he already has =864 cards
9514 1404 393
Answer:
3√3 square units
Step-by-step explanation:
The area of a regular n-sided polygon with radius r is given by the formula ...
A = (n/2)r²·sin(360°/n)
For n=3 and r=2, the area is ...
A = (3/2)(2²)·sin(360°/3) = 6·sin(120°) = 6(√3/2)
A = 3√3 . . . . square units
_____
<em>Alternate solution</em>
The center of this polygon is the centroid, which divides each median into parts with the ratio 2:1. This means the given radius is 2/3 of the height of the triangle. The base of the triangle is 2/√3 times the height, so is ...
b = (2/√3)(3) = 2√3
The area using these dimensions is calculated as ...
A = 1/2bh
A = 1/2(2√3)(3) = 3√3 . . . . square units
Answer: 992 feet
Step-by-step explanation:
A road is inclined at an angle of 14 degrees. After driving 4100 feet along the food, find the drivers increase in altitude
applying sin rule on the triangle
Sin = opposite/hypotenuse
sin 14 = x / 4100
x = sin 14 × 4100
x = 0.2419 × 4100
x = 991.8 = 992
drivers increase in altitude = 992 feet
