sukhopar [10]2 years ago

Answer:

multiple choice is worth 2

short response is worth 4

Step-by-step explanation:

23x + 10y = 86

28x + 5y = 76

solve by elimination

multiply the top by -1 and the bottom by 2

-23x + -10y = -86

56x + 10y = 152

add them

33x = 66

x = 2

with x = 2 plug x into one of the equations

23x + 10y = 86

23(2) + 10y = 86

46 + 10y = 86

10y = 40

y = 4

x = 2 and y = 4 so

multiple choice is worth 2

short response is worth 4

Light travels at 186,000 miles per second. How many FEET does it travel in a microsecond? (A microsecond is a millionth of a sec
Maslowich
1 mile is 5,280 ft, and 1 second has 1,000,000 microseconds.
So 186,000 miles per second multiplied by 5,280 feet per mile gives 982,080,000 feet per second.
Dividing this value by 1,000,000 microseconds per second gives the final answer of 982.08 feet per microsecond.

A six-sided number cube is rolled twice.
Marina CMI [18]

Answer: A and D

Step-by-step explanation:

Dependent events mean that one event depends on the outcome of the previous event.

A) If the first roll is a 3, and we want to sum more than 7 with the second roll, then the possible outcomes 5 and 6. Now if the first roll is 4, then the possible outcomes for the second event will be 4, 5 and 6. So you can see how the outcome space of the second event changes depending on the first event, so the events are dependent.

B) Here we do not have dependence, each event only depends on it's own outcome.

C) Again, both events only depend on it's own outcome, so the events are not dependent.

D) This is similar as the case for A, these events are dependent because is not the same if the outcome of the first event is 3, than if the outcome is 5 (the outcome needed for the second roll changes depending on the outcome of the first event)

E) Same as B and C, the events are independent.

4. (03.06 MC)
bazaltina [42]

Step-by-step explanation:

Volume of a cylinder is:

V = πr²h

V = (3.14) (4 in)² (5 in)

V = 251.2 in³

Volume of a cone is:

V = ⅓ πr²h

V = ⅓ (3.14) (4 in)² (15 in)

V = 251.2 in³

The volumes are equal.

adoni [48]

Answer:

S=45m+15

Step-by-step explanation:

we have

E------>the number of sit-ups

m---->  the time in minutes

S----> the number of sit-ups after drinking the sports drink

E=15m+5 ----> equation A

S=3E ----> equation B

substitute the equation A in the equation B

S=3(15m+5)

S=45m+15
