Answer:

sin30°=x/50

1/2=x/50

2x=50×1

2x=50

x=50/2

x=25

tan30°=25/y

[tex] \frac{1}{ \sqrt{3 } } = \frac{25}{y} \\ y = 25\sqrt{3} [/tex]

tom drives at a constant rate of 40 miles per hour for 3 hours.how far will he travel at that time?
A.350 mi.
B.220 mi.
C.120 mi.
D. 60 mi.

Answers

Answer: C. 120 mi.

Step-by-step explanation:

To get the answer C you take the constant rate which is 40 and multiply it by the amount of hours which is 3. Hope this helps!

Answer:

C. 120 mi.

Step-by-step explanation:

If he is constantly going 40 miles per hour. That means every hour, he goes 40 miles. So if he drives 3 hours, he would drive 120 miles because 40 miles +40 miles+40 miles=120 miles. Aka 40 times 3 to get 120 miles.

A fish is hovering at –320 feet in relation to sea level. Then it descends 2 feet per second for 8 seconds. Brenda says that the new position of the fish in relation to sea level is represented by the equation below.

2 times 8 + (negative 320) = 336

Which explains whether Brenda is correct?
1. Brenda is correct because her answer represents 336 feet below sea level.
2. Brenda is correct because Negative 16 + (negative 320) = 336.
3. Brenda is not correct because the new position is 2 times 8 + (negative 320) = negative 304.
4. Brenda is not correct because the equation should be Negative 2 times 8 + (negative 320) = negative 336.

what is the answer 0,12km² a m² show work

Answers

Answer:

120 000 m^2

Step-by-step explanation:

I ASSUME you're being asked to convert from km^2 to m^2.

For this you need to identify the conversion rate, which is 1 000 000 m^2 / 1 km ^2. Multiply by the thing you're converting from and cancel the units.

(1 000 000 m^2 / 1 km ^2) x 0,12 km^2 = 120 000 m^2 (the km^2 cancels out, leaving you only with your target unit of m^2)

2 4/5−1 1/2


as a fraction

Answers

The answer is 1 3/10. This is because if we turn them into a mixed fraction we get 14/5 and 3/2. Then we find the least common denominator which is 10. So we multiply 5x2 and 14x2 to get a new fraction of 28/10 and then multiply 3x5 and 2x5 which gets us 15/10. Now that both fractions have a common denominator we can just subtract 28/10-15/10 which is 13/10 which is equal to 1 3/10.

Which product is negative? −7⋅(−3)⋅(−5)⋅(−8) −3⋅(−4)⋅(−9)⋅0 −2⋅(−4)⋅8⋅(−1) 6⋅(−2)⋅(−3)⋅1

Answers

Answer:

-2(-4)(8)(-1)

Step-by-step explanation:

The first choice goes like this:

negetive times negetive times negetive times negetive

and negetive times negetive will always be positive. So teh first choice simplified will be positive times positive which is postive of course. so the first choice is a no-no

the second choice goes lke this:

negetive times negetive times negetive times 0

negetive times negetive= positive

positive times negetive= negetive

BUT

negetive times 0 equals 0, and 0 is positive. So 2nd choice is a no-no

the 3rd choice goes like this:

negetive times negetive times positive times negetive

negetive times negetive equals positive

positive times positive=posive

positve times negetive= negetive

so choice 3 is a yes-yes!

p.s if you see theese kinds of problems dont numerically solve it, just think about negetives and positives, hope it helps ! :>

p.p.s
