Answer: -10 degress is colder than -4
so the answer will be: C (-10 < -4)
Step-by-step explanation:
Answer:
Cos A=5/13
we have
Cos² A=
25/169=1-Sin²A
sin²A=1-25/169
sin²A=144/169
Sin A=
again
Tan B=4/3
P/b=4/3
p=4
b=3
h=
Now
Sin B=p/h=4/5
in IV quadrant sin angle is negative so
Sin B=-4/5
CosB=b/h=3/5
Now
<u>S</u><u>i</u><u>n</u><u>(</u><u>A</u><u>+</u><u>B</u><u>)</u><u>:</u><u>s</u><u>i</u><u>n</u><u>A</u><u>c</u><u>o</u><u>s</u><u>B</u><u>+</u><u>C</u><u>o</u><u>s</u><u>A</u><u>s</u><u>i</u><u>n</u><u>B</u>
<u>n</u><u>o</u><u>w</u><u> </u>
<u>substitute</u><u> </u><u>value</u>
<u>Sin(A+B):</u>12/13*3/5+5/13*(-4/5)=36/65-4/13
<u>=</u><u>1</u><u>6</u><u>/</u><u>6</u><u>5</u><u> </u><u>i</u><u>s</u><u> </u><u>a</u><u> </u><u>required</u><u> </u><u>answer</u>
5.000or just 5
Hope this helps
Answer:
The reasoning is a deductive.
The reason is because the pattern of thought is logical, here, scientific methods ( i.e mathematically obtaining and comparing the density of the coin and the gold ) are used to support the conclusion.
Step-by-step explanation:
Gnerally the reasoning is a deductive.
The reason is because the pattern of thought is logical and scientific methods (eg mathematical equation (formula for density)) are applied to arrive at the conclusion.
Answer:
e ≥ 114 where e is the number of envelopes
Step-by-step explanation:
Let the number of envelopes for invitations to address be --------e
Hence the inequality of the number of envelopes is : e ≥ 140
Number of addressed envelopes is : 26
Remaining number of envelopes to address is : 140 -26 = 114 or more
The inequality that describes how many more invitations must be addressed is ;
e ≥ 114
