Answer:
It is impossible for us to answer that question as <em>we </em>weren't provided with a text to analyze.
Step-by-step explanation:
Answer:
p= 21
Explanation:
FIRST DO
3(21) -7
3 × 21 = 63
63 - 7 = 56
THEN DO
6(21) - 2
6 × 21 = 126
126 - 2 = 124
FINALLY
It needs to add up to 180°
124 + 56 = 180°
Therefore, the value of p = 21
Hope this helps!!! :)
1) You have vertical angles here. This means the big and small triangles are similar, meaning the ratio of corresponding sides of the two triangles are equal.
In this case, 32cm corresponds to 4cm and 40cm corresponds to x. To find x, set up the ratio as follows: 4/32 = x/40.
4/32 can be reduce to 1/8. Multiply each side by 40 to isolate x. you get 1/8 * 40
This yields x = 5 cm
2) set up a proportion, similar to the first question.
(x + 4)/8 = (2x + 1)/12
12(x + 4) = 8(2x + 1)
12x + 48 = 16x + 8
40 = 4x
x = 10
the length of BC is (x + 4) + (2x + 1) = 3x + 5
this means BC = 35
Divide 25 by 1 2/3 or 1.66 and then round down to get 15
Answer:
The answer is 3
Step-by-step explanation:
0.7*3 = 2.1
Think of it this way
its basically 7 times what equals 21?
then you find out 7 timex 3 = 21
and then put the decimals
0.7 times 3 (0.7 + 0.7 + 0.7) = 2.1
