Determine whether the forces in the pair are pulling at right angles to each other.

prohojiy [21]

Answer:

C) 3.0

Step-by-step explanation:

Let the length of the other side be x.

Using Pythagoras theorem for right-angled triangle,

4.2^2=2.9^2+x^2

or,x^2=4.2^2-2.9^2

or,x^2=9.23

or,x=√9.23=3.0 units

Trucks that travel on highways have to stop at various locations to be weighed and inspected for safe brakes and light systems.

IrinaVladis [17]

Answer:

The reuired probability is 0.756

Step-by-step explanation:

Let the number of trucks be 'N'

1) Trucks on interstate highway N'= 76% of N =0.76N

2) Truck on intra-state highway N''= 24% of N = 0.24N

i) Number of trucks flagged on intrastate highway = 3.4% of N'' = $\frac{3.4}{100}\times 0.24N=0.00816N$

ii) Number of trucks flagged on interstate highway = 0.7% of N' = $\frac{0.7}{100}\times 0.76N=0.00532N$

Part a)

The probability that the truck is an interstate truck and is not flagged for safety is $P(E)=P_{1}\times (1-P_{2})$

where

$P_{1}$ is the probability that the truck chosen is on interstate

$P_{2}$ is the probability that the truck chosen on interstate is flagged

$\therefore P(E)=0.76\times (1-0.00532)=0.756$

The distance to the top of the flagpole from where the student is standing is 240 feet. What is the approximate angle of elevati

lys-0071 [83]

answer is 1.566 deg

Step-by-step explanation:

The angle of elevation is given by the formula

tanθ = height/distance

tanθ = H/ 240

tanθ × 240 = H

θ =( tan∧-1) 240

= <u>1.566 deg</u>

what is the density of a sheet of aluminum that has a volume of 328.4 cubic centimeters and a mass of 780 grams

Nata [24]

Answer:

$\large\boxed{density=\dfrac{1950}{821}\ \dfrac{g}{cm^3}\approx2.375\ \dfrac{g}{cm^3}}$

Step-by-step explanation:

$density=\dfrac{mass}{volume}\\\\\text{We have}\\\\mass=780\ g\\volume=328.4\ cm^3\\\\\text{Substitute:}\\\\density=\dfrac{780g}{328.4\ cm^3}=\dfrac{780\cdot10}{328.4\cdot10}\ \dfrac{g}{cm^3}=\dfrac{7800}{3284}\ \dfrac{g}{cm^3}=\dfrac{7800:4}{3284:4}\ \dfrac{g}{cm^3}\\\\=\dfrac{1950}{821}\ \dfrac{g}{cm^3}$
