Leonard, Brandon, and Emily are tossing a football. The distances they stand from each other are shown in the diagram at the right. To the nearest tenth, what is the measure of the angle with its vertex at Leonard?
33.4°
Step-by-step explanation:[tex]AB=22tt[/tex]
[tex]BC=34tt[/tex]
[tex]AC=40ft[/tex]
[tex]cos\ C=\frac{AC^2+BC^2-AB^2}{2AC\bullet BC}[/tex]
[tex]=\frac{{40}^2+{34}^2-{22}^2}{2\times40\times34}[/tex]
[tex]=\frac{1600+1156-484}{2720}[/tex]
[tex]=\frac{2272}{2720}=\frac{71}{85}[/tex]
[tex]< c=arccos\left(\frac{77}{85}\right)\ \ \ \ \ \left\{\begin{matrix}the\ nearest\ tenth\\0.1\\\end{matrix}\right\}[/tex]
[tex]< C\thickapprox 33.4\textdegree[/tex]

What is the area of the shaded sector of the circle?
A: 9π units²
B: 27π units²
C: 81π units²
D: 162π units²
Answer:
B: 27π units²
Step-by-step explanation:
Formula
[tex]\textsf{Area of a sector of a circle}=\left(\dfrac{\theta}{360^{\circ}}\right) \pi r^2[/tex]
where:
[tex]\theta[/tex] is the angle[tex]r[/tex] is the radiusSolutionGiven:
[tex]\theta[/tex] = 120°[tex]r[/tex] = 9Substituting given values into the formula:
[tex]\begin{aligned}\implies \textsf{Area of a sector of a circle }& =\left(\dfrac{120^{\circ}}{360^{\circ}}\right) \pi \cdot 9^2\\ & = \dfrac13 \cdot \pi \cdot 81\\ & = 27 \pi\: \sf units^2\end{aligned}[/tex]
The area of the asked sector is 27π units².
What is a sector of a circle?A sector of a circle is a portion or part of a circle that is composed of an arc and its two radii.
Given that a circle L, we radius 9 and a central angle of 120°, we need to find the area of the sector, which is intercepted by the central angle,
So,
The area of a sector of a circle = central angle / 360° × area of the circle,
So,
A = 120°/360° × π × 9²
= 1/3π × 81
= 27π
Hence, the area of the asked sector is 27π units².

order 130 in, 4 yd in 10 ft from greatest to least
Answer: 4 yd, 130 in, 10ft
Step-by-step explanation:
So first you turn everything into inches
130 inches is already in inches.
4 yards = 12 ft
1ft = 12 in
12 *12 = 144 in
so 4 yards is 144 inches
10 ft = 12*10
12*10 = 120
so 10ft is 120 inches
144 inches is the greatest and 120 inches is the least.

Answer:
what will be the price of the next model= 59,748
Step-by-step explanation:
7748 is 14.9% of 52000
Solution:
What is 14.9% of 52000?
Y is 14.9% of 52000
Equation: Y = P% * X
Solving our equation for Y
Y = P% * X
Y = 14.9% * 52000
Converting percent to decimal:
p = 14.9%/100 = 0.149
Y = 0.149 * 52000
Y = 7748
To find the price for the next model
7748 + 52000

A movie theater sells two sizes of popcorn, large and small, in bags shaped like rectangular prisms. The small bag has a height of 5.5 inches, a length of 5 inches, and a width of 3 inches. The large bag has the same width and length as the small bag, but two times the volume. What is the height of the large bag of popcorn?
the solution is:
u should at the first find the volume of the small bag that V= LWH ( Lenght, width, height)
so it will be 82.5
since the Volume of the large bag is 2 times the volume of the small bag so the volume of large bag will be 165
so H = V / LW
H = 165 / 5×3
H = 165 / 15
So the Answer is H = 11
