5 0

Hi there!

Since any number multiplied by the number 1 is the same number, we can conclude that the identity of 5/6 stays the same since it has been multiplied by 1.

Hope this helps!

BC is tangent to circle A at B and to circle D at C. AB= 10 BC= 21 DC= 8 find AD to the nearest tenth

Andrei [34K]

The attached diagram is an interpretation of the question.
If there are other details, please post.

The distance AD is found by Pythagoras theorem, with
AD=sqrt(BC^2+(AB-DC)^2)=sqrt(21^2+2^2)=sqrt(441+4)=sqrt(445)
=21.095 (to the third decimal place)

Translate the sentence into an inequality. Eight times the sum of a number and 27 is at most "-15." Use the variable y for the u

strojnjashka [21]

Answer:

8(y + 27) ≤ -15

Step-by-step explanation:

In the given inequality statement, "Eight times the sum of a number and 27 is at most "-15""

The first part, "Eight times the sum of a number and 27" means that 8 is multiplied to the sum of y and 27. While the phrase "at most" means "less than or equal to (≤)" The phrase also implies that the value of y can be -15, or any value less than -15.

Therefore, the correct algebraic expression is: 8(y + 27) ≤ -15

A ship is sailing on the sea. It travels 50 miles at 60° to the horizontal. Then the ship travels 90 miles at 30° to the horizon

pav-90 [236]

Answer:

$(25\sqrt{3}+45)\ miles$

Step-by-step explanation:

we know that

The total vertical distance (total miles North) traveled is equal to

$d=50sin(60^o)+90sin(30^o)$

Remember that

$sin(60^o)=\frac{\sqrt{3}}{2}$

$sin(30^o)=\frac{1}{2}$

substitute

$d=50(\frac{\sqrt{3}}{2})+90(\frac{1}{2})$

$d=(25\sqrt{3}+45)\ miles$

Doug regularly mows his neighbor's lawn. Last month, Doug's neighbor paid him $55 for 6 hours of mowing. Is this situation most

nasty-shy [4]

Solution:

we are given that

Last month, Doug's neighbor paid him $55 for 6 hours of mowing.

we have been asked that

Is this situation most likely a proportional relationship?

yes..its as proportional relationship.

Because the amount that Doug get is $55 for 6 hours

It mean for each hour Doug get is $\frac{55}{6}$ $

It mean if you increase the number of hours then the number of dollars get paid also increases. Hence the given situation is most likely a proportional relationship.
