Which statement would be true if you evaluate the expression 15x(465x4)

Mathematics
1 answer:
Morgarella [4.7K]3 years ago

Answer:

c. the solution is 3 times as large as 5x(465x4)

Step-by-step explanation:

I assume you are using the letter x as the multiplication sign.

Start with:

15 x (465 x 4)

We know that 15 = 3 x 5

Now we replace 15 with 3 x 5 in the original expression.

15 x (465 x 4) = 3 x 5 x (465 x 4)

Answer: c. the solution is 3 times as large as 5x(465x4)

Please help! It would be very much appreciated :)
Trava [24]

Answer:

  1. Cos 45=6/x

x=6/cos 45=6√2

x=6√2

tan 45=y/6

y=tan45 ×6

y=6

2.

sin 60=y/10

y=sin60×10

y=5√3

again

Cos 60=x/10

x=½×10

x=5

3.

Sin 45=x/5

x=1/√2×5 or

x=5√2/2

again

y=5√2/2 or 5/√2[base angle of right angled isosceles triangle]

4.

Sin 30=8/x

½×x=8

x=8*2

x=16

again

cos 30= y/x

√3/2×16=y

y=8√3

5.

sin 60=7/x

x=7/[√3/2]

x=14/√3 or 14√3/3

again

cos 60=y/x

½×14√3/3=y

7√3/2=y

y=7√3/2

What is the solution to the inequality?
Alexxx [7]

Answer:

Oc. x>11

Step-by-step explanation:

Subtract 4 from 4 which will give you 0, then subtract 4 from 15 which should give you 11. x is still greater than 11. You don't switch the signs unless you're dividing or multiplying by a negative number. Hope this helps.
