Write two numbers so that the numbers are in order. ________;6,010;_________;5,060
djyliett [7]
I'm not sure if that's what you mean, but the difference between 6010 and 5060 is 950, so to find a number in a halfway between them I divided 950 by 2 (which is 475) and added it to 5060 (or substracted from 6010 - it's the same). Next I added the same number (475) to 6010. So finally it would like like this:

6,485 ; 6,010 ; 5,535 ; 5,060

One number is 7 more than another. The difference between their squares is 161. What are the numbers?
sergeinik [125]
X is 7 more than y
x>y then
difference betwen squares is 161 so


x=7+y
and
x²-y²=161

so
x=7+y
sub that for x in other equation

(7+y)²-y²=161
y²+14y+49-y²=161
14y+49=161
minus 49 both sides
14y=112
divide both sides by 14
y=8

sub back

x=7+y
x=7+8
x=15

the numbers are 15 and 8

Using the diagram, find sin B. Express your answer as a decimal rounded to the nearest hundredth, such as .86 or 0.86.
inessss [21]
Hi, thank you for posting your question here at Brainly.

This problem could be solved using the Law of Cosines, since we are given with the three sides. The equation goes,

b^2 = a^2 + c^2 - 2accosB. Substituting,

24^2 = 7^2 + 25^2 - 2(7)(25)cosB

Then B = 73.7 degrees. Therefore sinB or sin(73.7) = 0.96.
