a delivery truck is carrying and 8713 lb load of pet food. At a weighing station, the loaded truck weighs 17200 lb. What is the
netineya [11]

We know that the load is 8713 lbs.

The total weight (truck + load) is 17200 lb.

Then, we can calculate the weight of the empty truck as:

\begin{gathered} L=8713 \\ W=L+T=17200 \\ \Rightarrow T=W-L \\ T=17200-L=17200-8713=8487 \\  \end{gathered}

Answer: the empty truck's weight is 8487 lb.

T: empty truck's weight

W: total weight (loaded truck's weight)

L: Load

The equation is:

T = W - L

Square P and Square Q are similar squares. The ratio of the side length of Square P to the side length of Square Q is 2:7. If th
Fiesta28 [93]

Answer:

49 inches

Step-by-step explanation:

since we are talking about squares, and each side in a square has the same length, and all 4 angles are 90 degrees, "similar" did not mean much. every square is similar to every other possible square.

they all are bigger and smaller copies of themselves.

but how much bigger ?

in our case here P is the smaller square and Q the bigger one.

x = side length of P = 3.5"

y = side length of Q

x/y = 2/7

3.5/y = 2/7

7×3.5 = 2y

y = 3.5×3.5 = 12.25"

the perimeter of Q is

4×y = 4×12.25 = 49"

Sabendo que senx=3/5 e que X € 1°quadrante, calcule tgx
guapka [62]
<span>se 
sen x = 3/5 eleva ao quadrado ambos os lados 
sen² x = (3/5)² 

Tem que partir da relação fundamental 

sen²x + cos²x = 1 
(3/5)² + cos² x = 1 

cos² x = 1 - (3/5)² = 16/25 

cos x = V(16/25 = 4/5 

b ) tg x = sen x / cos x = 3/5 / 4/5 = 3/5 * 5/4 = 3/4 

c) cotg x = cosx / sen x = 1 / tgx = 1/ (3/4 = 4/3 

d) sec x = 1/ cos x = 1 / 4/5 = 5/4 

e) cossec x = 1 / sen x = 1/ 3/5 = 5/3
