I need help thanks so much
Lerok [7]

Answer:

c. 1 \frac{3}{8} inches

Step-by-step explanation:

Since the paper clip is past the 1, the answer will be 1 and ___.

the mark in the middle of the 1 and 2 is one half (1/2)

the mark in between the 1 and 1/2 is 1/4

the mark between 1/4 and 1/2 is 1/8

there are three (3) 1/8 marks where the paperclip is

3 * 1/8 = 3/8

so your answer is 1 3/8

hope this helps:)

Answer:

6÷25

Step-by-step explanation:

Favourable outcomes are 6,and the total outcomes are

6 + 4  + 15 = 25

So the probability of getting fed marble is Favourable outcome ÷ total outcome=6÷25.

Solve r = cs/d for c
Nady [450]
r=\frac{cs}{d}\\\\\frac{cs}{d}=r\ \ \ \ |multiply\ both\ sides\ by\ d\\\\cs=dr\ \ \ \ \ \ |divide\ both\ sides\ by\ s\\\\\boxed{c=\frac{dr}{s}}

Two forces with magnitudes of 150 and 100 pounds act on an object at angles of 30° and 120°, respectively. Find the direction an
lyudmila [28]
<h2>Answer:</h2>

Magnitude=180.27 \ lbf \\ \\ Direction=63.69 \ degrees

<h2>Step-by-step explanation:</h2>

We have two forces as follows:

<u>First force:</u>

Magnitude: 150 pounds

Angle: 30°


<u>First force:</u>

Magnitude: 100 pounds

Angle: 120°


So the components can be found as follows:

F_{1x}=150cos(30)=129.90 \ lbf\\F_{1y}=150sin(30) = 75 \ lbf \\ \\ F_{2x}=100cos(120)=-50 \ lbf\\F_{2y}=100sin(120) = 86.60 \ lbf


So the components of the resultant force can be found by adding each component of the individual forces as follows:

R_{x}=\Sigma F_{x} \\ R_{y}=\Sigma F_{y} \\ \\ R_{x}=129.90-50=79.90 \ lbf \\ R_{y}=75+86.60=161.6 \ lbf


Finally, the magnitude and direction of the resultant force is:

Magnitude \rightarrow R=\sqrt{R_{x}^2+R_{y}^2}=\sqrt{79.90^2+161.6^2}=180.27 \ lbf \\ \\ Direction \rightarrow \theta=tan^{-1}(\frac{R_{y}}{R_{x}})=tan^{-1}(\frac{161.6}{79.90})=63.69 \ degrees
