Kiyoshi paints 1/3 of the fence each hour.
When the friends work together, they paint 1/2 of the fence each hour.
So Red must be painting (1/2 - 1/3) = 1/6 of the fence each hour.
The rate of 1/6 fence per hour means 1 fence per <em>6 hours</em> for Red alone.
Answer:
(7^2)^2
7^2 / 7^-2
Step-by-step explanation:
7^-2 * 7^6
We know that a^b * a^c = a^ (b*c)
7^ (-2+6)
7^ 4
This is also 7^2 ^2
We also know that
7^2 / 7^-2
We know a^b / a^c = a^ (b-c)
7^(2 - -2) = 7^ (2+2) = 7^4
1/2 and -1/2
hope it helps, brianliest pls
Answer:
m<RST = 32°
m<TSQ = 58°
Step-by-step explanation:
m<RST here, meaning the angle of the whole diagram is 90 degrees as you can see.
m<RSQ + m<TSQ = m<RST
15x — 43 + 8x + 18 = 90
23x — 25 = 90
+25 +25
---------------------------
23x = 115
/23 /23
----------------------------
x = 5
Now, plug this into the equation for m<RSQ and m<TSQ to find their values.
m<RSQ = 15x — 43
= 15x - 43
= 15(5) - 43
= 75 - 43
= 32
m<TSQ = 8x + 18
= 8x + 18
= 8(5) + 18
= 40 + 18
= 58
Now, check to see if our values are right or not.
15x — 43 + 8x + 18 = 90
15(5) — 43 + 8(5) + 18 = 90
75 - 43 + 40 + 18 = 90
32 + 40 + 18 = 90
90 = 90 <u>CORRECT</u>
