It takes 0.26 minutes to travel 1000 feet
<u>Solution:</u>
Given that car traveling at a constant speed travels 175 miles in four hours
Distance = 175 miles
Time taken = 4 hours
Convert the units to feet and minute
Given that,
1 mile = 5280 feet
175 miles = 5280 x 175 feet = 918720 feet
Also we know that,
1 hour = 60 minutes
4 hours = 60 x 4 minutes = 240 minutes
Thus, we got,
Distance = 918720 feet
Time taken = 240 minutes
<em><u>Find the speed of car</u></em>
<em><u>Speed is given by formula:</u></em>
Thus speed of car is 3828 feet per minute
<em><u>How many minutes will it take for the car to travel 1000 feet?</u></em>
Let "x" be the minutes needed for 1000 feet
speed of car is 3828 feet per minute
1 minute = 3828 feet
x minute = 1000 feet
This forms a proportion. We can solve by cross multiplying
Thus it takes 0.26 minutes to travel 1000 feet

<u>We can use the </u><u>formula.</u><u> </u>
c1v1 =c2v2
<u>Where c1 is the concentration and v1 is volume of the concentrated </u><u>solution.</u><u> </u>
c2 is the concentration
and v2 is the volume of the diluted solution to be prepared
9.00 M x V1 = 2.75 M x 350 mL
V1 = 106.9 mL
<u>Volume of 106.9 mL from the concentrated solution should be taken and diluted to 350 </u><u>mL</u><u>.</u>
Answer:
O, S, Te
Cl, Br, Se
Explanation:
Main group elements have an electronegativity that increases across a period (from left to right) and decreases down a group.
Each atom has its own value which you can find on the electronegativity chart.
Metals have low values
Nonmetals have high values
I'm your case:
O = 3.5
S = 2.5
Te = 2.1
Cl = 3.0
Br = 2.8
Se = 2.4
So that other scientist can repeat their experiments
i hope i got i right
Answer:
180 degrees
Explanation:
sp hybridization generates orbitals that overlap linearly, generating a straight line. This leads to an angle measurement of 180 degrees.
