H=vt-16t²
vt-16t²=H
vt=16t²+H
v=(16t²+H)/t
v=16(t²/t)+H/t
v=16t+H/t
Answer: the answer would be: v=16t+H/t
Answer:
.
Step-by-step explanation:
Given:
Tina cut 3 wood boards each into 4 equal pieces.
She used 3 of the pieces for a craft.
Question asked:
What fraction of the boards does she have left ?
Write this fraction as a mixed number.
Solution:
<em><u>As she cuts 3 wood board each into 4 equal pieces :-</u></em>
Total number of equal pieces = 
Pieces of wood used = 3
Remaining pieces = 12 - 3 = 9
<h3>
<u><em>Now, we will write these 9 pieces in terms of number of wood boards</em></u>.</h3>
<u>By unitary method:</u>
4 pieces constitute = 1 wood board
1 piece constitute = 
9 pieces constitute = 
<em>Now, convert it into mixed fraction:</em>

Therefore, fraction of the boards she have left is
.

Answer:
70° and 110°
Step-by-step explanation:
Supplementary angles sum to 180°
sum the parts of the ratio, 7 + 11 = 18 parts
Divide 180° by 18 to find the value of one part of the ratio.
180° ÷ 18 = 10° ← value of 1 part, thus
7 parts = 7 × 10° = 70°
11 parts = 11 × 10° = 110°
The 2 angles are 70° and 110°
