Answer:
.
Step-by-step explanation:
Answer:
she can knit 1/2 a yard of a blanket in 1 hour.
So it would look like this
1/2 a yard of blanket
-----
1 hour
It would be, she can knit one half of a yard of blanket in one hour
one half over oner hour
Answer:
17.3
Step-by-step explanation:
tens ones. tenths hundredths thousandths
1 7 . 2 5 3
We are rounding to the nearest tenth
We are rounding the 2 so we look at the 5. If it is 5 or above we round up.
Since it is, we will round the 2 to a 3
17.3
Answer:
- sin C=h/a
- substitution property of equality
- commutative property of multiplication
Step-by-step explanation:
Because two points determine a line, you can draw altitude BD perpendicular to AC with height h. By the definition of a sine ratio, <u>sin(C) = h/a</u>, which can be rearranged into a·sin(C) = h. The area of △ABC is A=1/2bh. The <u>substitution property of equality</u> can be used to write A=1/2b(a sinC), which becomes A=1/2ab(sinC) by the <u>commutative property of multiplication</u>.
___
The mnemonic SOH CAH TOA reminds you that the sine ratio is ...
Sin = Opposite/Hypotenuse
Here, the side of the right triangle opposite angle C is designated "h", the height of ∆ABC. The hypotenuse of that right triangle is side "a". So ...
sin(C) = h/a
__
The substitution property of equality lets you replace any expression with its equal. Here, we have h=a·sin(C), so we can use a·sin(C) in place of h in the formula for triangle area:
1/2bh = 1/2ba·sin(C)
__
The commutative property of multiplication lets you rearrange the order of the factors in a product, so ...
ba = ab
and
A = 1/2ba·sin(C) = 1/2ab·sin(C)
Answer:
your answer should be 56.52 .
Step-by-step explanation:
this reason because is because radius is usually half of the diameter so just multiply 28.26 by 2
