Answer:

10.2

Step-by-step explanation:

Using Pythagoreans theorem, i did A^2 + B^2 = C^2

in this case,

4^2 + x^2 = 11^2

16 + x^2 = 121

x^2 = 105

square root both sides

you get 10.2469508

or 10.2

Answer:

172.12 in²

Step-by-step explanation:

Consider the figure as 3 parts: semicircle with radius of 4 in, rectangle with 7x9 in and rectangle 6x14 in.

Area of semicircle:

A = 1/2*πr² = 1/2*3..14*4² = 25.12 in²

Area of rectangles:

7*9 = 63 in²
6*14 = 84 in²

Total area:

25.12 + 63 + 84 = 172.12 in²

A farmhouse shelters 11 animals. Some are goats and some are ducks. Altogether there are 34 legs. How many of each animal are th

andriy [413]

We are given that there are 11 animals with a total of 34 legs.

Let G = number of Goats, and D = number of Ducks

then G + D = 11; solving for G, we get G = 11 - D

then, 4G + 2D = 34

substituting the value for G, we get 4(11 - D) + 2D = 34

expanding, we get 44 - 4D + 2D = 34

solving, we get D = 5. Therefore, G = 6

Proof: (5 x 2) + (6 x 4) = 34

Answer:

$\large\boxed{Q1.\ 80\ cm^3}\\\boxed{Q2.\ 45\ in^3}\\\boxed{Q3.\ 48\ m^3}\\\boxed{Q4.\ A,\ D}\\\boxed{Q5.\ 96\ in^3}$

Step-by-step explanation:

$\text{The formula of a volume of a rectangular prism:}\\\\V=lwh\\\\l-length\\w-width\\h-height$

$\bold{Q1}\\\\l=10\ cm,\ w=4\ cm,\ h=2\ cm\\\\V=(10)(4)(2)=80\ cm^3\\\\\bold{Q2.}\\\\l=5\ in,\ w=3\ in,\ h=3\ in\\\\V=(5)(3)(3)=45\ in^3\\\\\bold{Q3.}\\\\l=4\ m,\ w=2\ m,\ h=6\ m\\\\V=(4)(2)(6)=48\ m^3\\\\\bold{Q4.}\\\\V=120\ ft^3\\\\\bold{A:(5)(4)(6)=120}\\B:\ (7)(7)(6)=294\\C:\ (3)(6)(4)=72\\\bold{D:\ (10)(3)(4)=120}\\\\\bold{Q5.}\\\\l=8\ in,\ w=4\ in,\ h=3\ in\\\\V=(8)(4)(3)=96\ in^3$
