Answer:
h = 10.92 m.
Step-by-step explanation:
The small triangle on the left is similar to the whole triangle, so:
12/20 = h/18.2
h = 12*18.2 / 20
h = 10.92 m.
-2(5)^2+2(5)-3
-2(25)+10-3
-50+10-3
-40-3
=-43
Answer:
C
Step-by-step explanation:
think of a random K number (like 3 for example)
1/2(3) = 3/2
this equals k/2 = 3/2
Answer:
x = 32
Step-by-step explanation:
this is an equilateral triangle where all sides measure the same value; therefore, 2x-4 = 5y
since we are solving for 'x' we can set up this equation:
3(2x-4) = 180
6x - 12 = 180
6x = 192
x = 32
Answer:
B
Step-by-step explanation:
30 are unusable in 200. So how many are unusable in 17,000??
<em>We can set up a ratio and figure out the answer right away! Let x be the number of unusable bolts in 17,000, so we can write:</em>
<em>
</em>
<em />
<em>THus, number of unusable bolts is 2550. B is right.</em>
