Answer:
-3
Step-by-step explanation:
-7b = 21
/ -7 / -7
b = -3
No because
15b + 4 = 25.6
15b = 21.6
b = 1.44
0.6+15b+4 = 25.6
4.6 + 15b = 25.6
15b = 21
b = 1.4
The answers are not the same therefore they are not equivalent.
Answer:
Assume ΔABC is an acute triangle.
Step-by-step explanation:
Given the triangle ABC.
We have to tell the first step of indirect proving ΔABC is not an acute triangle.
An indirect proof, also known a proof by contradiction. When we use indirect proof method, we assume the opposite of our theory to be true and then by applying our assumed theory we contradict the given statement which proves our supposition is wrong. In other words, we assume our theory is false.
Hence, our first step is to
Assume ΔABC is an acute triangle.
Third option is correct.
Answer:
B. (-r, 0)
Step-by-step explanation:
W is on the x axis, so the y coordinate is 0.
It is also r away from the origin, so the x coordinate is -r

Answer:
9.193259%
Step-by-step explanation:
In order to obtain the percentage of military members in the reserves who are Black, we will have to multiply the percentage of Black military members in the reserve by the percentage of military members in the reserve. This is calculated as follows:
Military members in the reserves who are Black (%) = 77.1771% × 11.9119%
= 9.193259%
Therefore, he percentage of military members in the reserves who are Black is 9.193259%
.
Example
For example, let assume the total number of active members in the military is 100.
To obtain the number of military members who are in the reserves, we multiply 77.1771% by 100. This gives us 78 approximately.
To obtain the number of military members in the reserves who are Black, we multiply 11.9119% by 78 we got above who are active military members in the reserves. This gives us 9 members approximately.
I wish you the best.
