Answer:
see answers below to match them
Step-by-step explanation:
12r + t - 4r + 6t
=12r - 4r + t + 6t
=8r + 7t
(12r+2t) - (4r+10t)
=12r + 2t - 4r - 10t
=8r - 8t
=8(r-t)
12(r+t)-6(r+t)+4(r+t)-2(r+t)
=(12-6+4-2)(r+t)
=8(r+t)
C=68
A= 61.
B= 119
Total degree of a triangle is 180 as well as the angle of a straight line
Answer:
The answer is : Yes y=2x+1 is linear
Step-by-step explanation:
The equation of a straight line can be written in several forms. ... y=2x−1 is in this form, therefore it is a linear equation. It has an x term, a y term and a constant.
Answer:
So, the following statement is a TRUE statement.
Step-by-step explanation:
In geometry Cavalieri's priciple states that:
Cavalieri's Principle: If, in two solids of equal altitude, the sections made by planes parallel to and at the same distance from their respective bases are always equal, then the volumes of the two solids are equal.
Hence, the given statement:
Cavalieri's principle states that two solids with equal heights and base areas have equal volumes is a TRUE statement.
Sample size, N = 3450
Point estimate of republican, p = 1789/3450 = 0.5186 = 51.86%
Z = 1.96 at 95% confidence level
Now,
True percentage of republican residing in California = p +/- Z*Sqrt [p91-p)/N] = 0.5186+/- 1.96* Sqrt [0.5186(1-0.5186)/3450] = 0.5186+/-0.017 = (0.5016,0.5356) = (50.16%,53.56%).
