Step-by-step explanation:
A+B+C=180° (Sum of angles in a triangle)
A+44°+119°=180
A+163°=180°
A=17°
Using Sine Rule
a/Sin A=c/Sin C
Subtitute the value of A, c and C into the formula
a/Sin 17°=15/Sin 119°
Cross Multiply
a=15Sin17°/Sin119°
a=5.01 (2 d.p)

Guess the rule and enter the missing number in the sequence. 23, 20, 17, 14,
Answer:
11
subtract 3
Step-by-step explanation:
The numbers are getting lower in value as you go,
So that means it is a subtracting sequence,
Take the first two numbers and subtract them,
23 - 20 = 3
So now subtract 3 from the others and see if it works,
20 - 3 = 17
17 - 3 = 14
14 - 3 = 11
11 is the missing number
Yep, it works,
Hence the sequence is to subtract three.

After crafting the function below, Brenda noticed at one point was missing. Which of the following is missing point in Brenda’s graph?
Using the function concept, it is found that the missing point was of (0,3), hence option A is correct.
What is the condition for a function?In a function, one value of the input can be related to only one value of the output.In a graph, it means that for each value of x(horizontal axis), there can only be one respective value of y(vertical axis).In the given graph, values are already defined for x = 1, x = 2 and x = 3, while no value is defined for x = 0.

Sarah takes 550 mg of an antibiotic. Every hour, her body breaks down 25% of the remaining drug. How much will be left after 12 hours?.
The amount of drugs that will be left after 12 hours is 17.42 mg provided Sarah takes 550 mg of an antibiotic every hour.
What is exponential decay?Exponential decay can be described as a reduced amount of an original substance by a definite percentage over a period of time. It can be determined by using the formula:
[tex]\mathbf{y = a(1 - r)^t}[/tex]
where;
y = total amount, a = initial amount = 550 mgr = the growth rate = 0.25t = number of growth periods = 12 hours[tex]\mathbf{y = 550(1 - 0.25)^{12}}[/tex]
y = 17.42 mg
Therefore, we can conclude that the amount of drugs that will be left after 12 hours is 17.42 mg.

11. State the zero product property.
Answer:
The Zero Product Property states that if the product of two numbers is zero, then at least one of the numbers is zero. In symbols, where a and b represent numbers, if ab=0, then a = 0 or b=0
Step-by-step explanation:
Answer:
The identity property of 0, also known as the identity property of addition, tells us that any number + 0 = the original number. Adding zero will not change the "identity" or value of the number you are adding it to. For example: 5 + 0 = 5.
6 + 0 = 6
1 + 0 = 1 ... etc.

each angle is 90° in a square, 120° for a hexagon, and the rest should hopefully be do-able.

which is not here
Step-by-step explanation:
Given :
breadth = 11/12 ft = 0.92 ft
height = 4 ft
length = 3 _ 3/4 ft = 3.75 ft
The volume of cuboid is l×b×h

Fie bought 3 yards of fabric at $9.35 per' yard and thread for another $2.99
ew a quilt. If she sold her quilt at a local craft fair for $45. how much profit
she make?
Answer:
$13.96
Step-by-step explanation:
1st, we figure out how much it cost to make the quilt. The thread cost $2.99. She bought 3 yards of fabric for $9.35 per yard, so the fabric cost $9.35 x 3 = $28.05.
The quilt cost $28.05 + $2.99 = $31.04
Profit is sales price less the cost of the item. It's the money left over.
Sales price $45.00 - cost $31.04 = $13.96 is her profit
