Answer:
95/2 mph
Step-by-step explanation:
speed of train = 60 mph
speed of car = x
"The speed of a train is 35 miles per hour less than 2 times the speed of a car."
2x - 35 = 60
2x = 95
x = 95/2
Answer: 95/2 mph

Do 2b+b and 3b have the same value for all values of b
Answer:
Expression 2b+b and 3b have same values for all values of b.
Step-by-step explanation:
Given the two expression 2b+b2b+b and 3b3b and values of b as 1, 2 and 3.
Consider first expression that is, 2b+b2b+b .
Substituting the value of b=1b=1 ,
2\left(1\right)+\left(1\right)=2+1=32(1)+(1)=2+1=3 ....1
Substituting the value of b=2b=2 ,
2\left(2\right)+\left(2\right)=4+2=62(2)+(2)=4+2=6 ....2
Substituting the value of b=3b=3 ,
2\left(3\right)+\left(3\right)=6+3=92(3)+(3)=6+3=9 ....3
Consider second expression that is, 3b3b .
Substituting the value of b=1b=1 ,
3\left(1\right)=33(1)=3 ....4
Substituting the value of b=2b=2 ,
3\left(2\right)=63(2)=6 ....5
Substituting the value of b=3b=3 ,
3\left(3\right)=93(3)=9 ....6
For value of b=1, equation 1 and equation 4 are same, for value of b=2, equation 2 and equation 5 are same and for value of b=3 equation 3 and equation 6 are same.
Therefore both expression are same for all values of b.

63° x Find the unknown angle measure
Answer:
The angle of the unknown measure is 27°.
Step-by-step explanation:
When we look at this angle, we can see it is a 90° angle. Since we already have 63° of the angle, we just subtract 90° from 63° and we get 27°. Therefore, 27° is our answer.

There are 85 mini chocolates in a bowl. The ration of kit kats to hersheys bars is 8:7. About how many kit kats were there?
Answer:
45
Step-by-step explanation:
Total mini chocolates in a bowl= 85
ration of kit kats to hersheys bars = 8:7
ration of kit = 8
Total ratio= 15
Number of kit kats= ratio of kit Kat/ total ratio × total number of mini chocolates
Number of kit Kat = 8/15 × 85= 45
Hence, there are 45 kit kats present there.
Answer:
There were about 45 kit kats.
Step-by-step explanation:
With the information provided, you know that the the ratio of kit kats to hersheys bars is 8:7 and that there are 85 mini chocolates in a bowl, so to be able to find the number of kit kats there first you can say that you have 15 units because if you add the numbers on the ratio 8+7=15. Then, you divide the total amount of mini chocolates by the units to find the number of chocolates in each unit:
85/15=5.66
Now, you can multiply the ratio of hersheys bars which is 7 for the number of chocolates per unit to find the amount of hersheys bars:
7*5.66=40
Finally, you can multiply the ratio of kit kats which is 8 for the number of chocolates per unit to find the amount of kit kats:
8*5.66=45
According to this, the answer is that there were about 45 kit kats.

Sinx = [tex]\frac{3}{8}[/tex]
Find cosx and tanx
Answer:
Cos(x) = sqrt(55) / 8; tan(x) = 3/sqrt(55)
Step-by-step explanation:
Sine is opposite over hypotenuse. So we get that the opposite is 3 and the hypotenuse is 8. To find the adjacent (which we'll need for cosine and tangent), we can use pythagoras' theorem. Therefore, 8^2 = 3^2 + A^2, where A is the adjacent. A then must equal sqrt(64-9) = sqrt(55).
Cosine is adjacent over hypotenuse, which is then sqrt(55) / 8. Tangent is opposite over adjacent, which is then 3 / sqrt(55) or (sqrt55)*3/55

under a 200:1 microscope, a microorganism appears to have a length of 0.75in, how long is the microorganism
Answer:
0.00375 inches
Step-by-step explanation:
Since the microscope makes the microorganism appear ×200 larger, that would mean we would have to divide by 200 to get the original size. 0.75/200= 0.00375.

Step-by-step explanation:
100 + 84 - 62x =494
184 - 62x =494
494-184 = -62x
310 =-62x
310/-62 =x
