Triangle abc is right triangle and sin (53)= 4/x. Solve for x and round to the nearest whole number

1 answer:

5 0

$\bf sin(53^o)=\cfrac{4}{x}\implies x=\cfrac{4}{sin(53^o)}\implies x\approx 5.0085\implies \stackrel{\textit{rounded up}}{x=5}$

make sure your calculator is in Degree mode.

The normal body temperature of a camel is 37°C. This temperature varies by up to 3°C throughout the day. Write and solve an abso

uysha [10]

The normal body temperature : to = 37° C
An inequality is:
| t - to | ≤ 3
| t - 37 | ≤ 3
t - 37 ≤ 3 AND ( - t - 37 ) ≤ 3
t ≤ 3 + 37 - t + 37 ≤ 3
t ≤ 40 - t ≤ 3 - 37
 - t ≤ - 34 / *( - 1 )
 t ≥ 34
Answer t ∈ [ 34°C, 40° C ].

A jar of 150 jelly beans contains 22 red jelly beans, 38 yellow, 20 green, 28 purple, 26 blue, and the rest are orange.Let B = t

pentagon [3]

Answer:

$P(R\ and\ B) = 0.0256$

Step-by-step explanation:

Given

$Red = 22$

$Yellow = 38$

$Green = 20$

$Purple = 28$

$Blue = 26$

$Orange = 16$

Required

Determine the probability of red then blue jelly? i.e. P(R and B)

From the question, we understand that the red jelly bean was not replaced. This means that the number of jelly beans reduced by 1 after the picking of the red jelly bean

So, we have:

$P(R\ and\ B) = P(R)\ and\ P(B)$
