Find x in each triangle

Nimfa-mama [501]

Answer:

x=20

Step-by-step explanation:

Since this is a right triangle, we can use the Pythagorean theorem

a^2 + b^2 = c^2

21 ^2 + x^2 = 29^2

441+x^2 =841

Subtract 441 from each side

x^2 = 841-441

x^2 = 400

Take the square root of each side

sqrt(x^2) = sqrt(400)

x = 20

Dmitry [639]

Answer:

<em>Answer: C.Fraction 11 and 1 over 4 cubic inches</em>

Step-by-step explanation:

The volume of a rectangular prism of length L, width W, and height H is given by:

V=LWH

The prism is packed with cubes of a side length of a=1/2 inch. The volume of each cube is:

$V_c=a^3=\left(\frac{1}{2}\right)^3=\frac{1}{8}\ in^3$

The prism is packed with L=5, W=3, and H=6, thus the volume (in cubes) is:

V=5*3*6=90\ cubes

Since each cube has a volume of $\frac{1}{8} in^3$ :

$V=90\cdot\frac{1}{8}=\frac{45}{4}$

Expressing as a mixed fraction:

$V=\frac{45}{4}=\frac{44+1}{4}=11\frac{1}{4}$

Answer: C.Fraction 11 and 1 over 4 cubic inches

Find the area of the figure below. Round your answer to one decimal place.

MAVERICK [17]

Answer: 57.1 (rounded)

Step-by-step explanation:

Area of triangle formula: 1/2 x base x height

Area of a semicircle: 1/2 x pi x r^2

(1/2 x 8 x 8) + (1/2 x pi x 4^2)

= 57.1 (rounded)

Minchanka [31]

Since we know the x and y, you would divide 480 by 15 and 32 miles per hour. Then you would multiply 7.2 by 32 and get 230.4. Your trying to find with wind and against wind so just times that by two and get 460.8. I think
