Answer:
Step-by-step explanation:
A1. C = 104°, b = 16, c = 25
Law of Sines: B = arcsin[b·sinC/c} ≅ 38.4°
A = 180-C-B = 37.6°
Law of Sines: a = c·sinA/sinC ≅ 15.7
A2. B = 56°, b = 17, c = 14
Law of Sines: C = arcsin[c·sinB/b] ≅43.1°
A = 180-B-C = 80.9°
Law of Sines: a = b·sinA/sinB ≅ 20.2
B1. B = 116°, a = 11, c = 15
Law of Cosines: b = √(a² + c² - 2ac·cosB) = 22.2
A = arccos{(b²+c²-a²)/(2bc) ≅26.5°
C = 180-A-B = 37.5°
B2. a=18, b=29, c=30
Law of Cosines: A = arccos{(b²+c²-a²)/(2bc) ≅ 35.5°
Law of Cosines: B = arccos[(a²+c²-b²)/(2ac) = 69.2°
C = 180-A-B = 75.3°

Answer:

Step-by-step explanation:
For 3 sides to be able to form a triangle, we need to check that the 2 shorter sides can "touch" when "stemming" out of the long side.
The long side has length 7cm, so the sum of 2 shorter sides must be bigger than 7cm for them to "touch". Note: if the sum was 7cm, the only way they would touch is if they were laid along the long side, so it would not be a triangle - it would be a segment.
Fortunately, 3cm + 5cm > 7cm, so we can form a triangle.

Given the triangles are similar, find y.
Answer:
y = 8
Step-by-step explanation:
6 ÷ 4 = 1.5
(y + 4) ÷ y = 1.5
y + 4 = 1.5 y
0.5 y = 4
y = 8
An initial population of 490 quail increases at an annual rate of 6%. Write an exponential
function to model the quail population. What will the approximate population be after 5 years?
Answer:
656
Step-by-step explanation:
Given data
Initila population= 490
Rate = 6%
TIme= 5 years
Let us apply the compounding expression
A=P(1+r)^t
substitute
A= 490(1+0.06)^5
A=490(1.06)^5
A=490*1.338
A= 655.62
Hence the approximate Quail population will be 656
A corner store sells two kinds of baked goods: cakes and pies. A cake costs $15 and a pie costs $13. In one
day, the store sold 9 baked goods for a total of $121. How many cakes did they sell?
a. 8 cakes
c. 7 cakes
b. 2 cakes
d. 4 cakes
Answer:
a. 8
Step-by-step explanation: Out of 12 baked goods sold , let the number of cakes sold, be x in number and pies sold were 12 − x in number. Total sell was $ 144 , 1 cake costs $ 14 and 1 pie costs, $ 8 ∴ 14 ⋅ x + ( 12 − x ) ⋅ 8 = 144 or 14 x − 8 x = 144 − 96 or 6 x = 48 ∴ x = 8
Marissa wrote her bike to the park and back up halfway to the park she stopped at the library she was one 310 miles from the library how many miles and miles to ride her bike and all now
Answer:
5 1/5 miles
Step-by-step explanation:
Given that :
Library is located halfway between park and home ;
Distance between library and park = 1 3/10 miles
Hence, total distance between park and home :
1 3/10 + 1 3/10 = 2 6/10
The distance driven :
Home to park ; park back home
2 6/10 + 2 6/10 = 4 12/10
4 + 12/10 = 4 + 1 2/10
= 5 2/10
= 5 1/5 miles

2.42*3.20 step by step
Answer:
7.744
Step-by-step explanation:
3.20=3.2
you can multiply just 242 and 32 then pop in the decimal point later
242*32=242*30 + 242*2
242*3*10=726*10=7260
242*2=484
7260+484=7744
2*3 (rounded version of numbers) is 6
so the answer after putting decimal point should be around 6
77.44 is way too hight
7.744 is decently close to 6
so the answer is 7.744
Pls help me do this proof, will give brainiest
Step-by-step explanation:
A lot of times, one of the hardest parts of proving anything is figuring out exactly what you're trying to prove. Fortunately for us, we already have it laid out. We're trying to prove the Pythagorean theorem, which says that on a right triangle with legs a and b and a hypotenuse c, the sides are related by the equation
[tex]a^2+b^2=c^2[/tex]
This particular proof uses similarity, cleverly splitting the original right triangle into three - the original, and two smaller ones. One fact about similar triangles that helps us is that corresponding sides are proportional. This fact is used for the second step of the proof:
[tex]\frac{c}{b}=\frac{b}{d}[/tex] and [tex]\frac{c}{a}= \frac{a}{f}[/tex]
For our proof, we're going to try to go off of this fact to build back the Pythagorean theorem. We'll need an a², a b², and a c² for that, and we can get the first two by cross multiplying each equations, giving us two new ones:
[tex]cd=b^2[/tex] and [tex]cf=a^2[/tex].
This is Statement 3, and we go to it through Multiplication. Next, we can add the two equations together to get the left side of the Pythagorean theorem, factoring a c out of the right side to give us:
[tex]a^2+b^2=cf+cd=c(f+d)[/tex]
This is Statement 4, and we used the Addition property of equality to get it.
Now, looking at the original figure, we can see that the lengths d and f add together to give us a c. We can express that fact with the equation
[tex]d+f=c[/tex]
This is Statement 5, given to us through the Segment addition postulate. Finally, we can use our equation from statement 5 to substitute f + d for c in our equation from Statement 4, giving us the Pythagorean theorem:
[tex]a^2+b^2=c\cdot c=c^2[/tex]
This is Statement 6, our final statement, and it uses the Substitution property of equality to finish our proof.
Give the sum in simplest form: 4/10 + 1/10 = _____
Answer:
1/2
Step-by-step explanation:
bc 4/10 + 1/10= 5/10 divided by 2 =1/2
Answer:
1/2 or 5/10
Step-by-step explanation:
When you are adding fractions you only add the numerator (the top number) 4+1=5. So you get 5/10. But then you have to divide to get the simplest form. You can divide 10 and 5 by 5. So then after you are done dividing you end up with 1/2!

What is
3(3 - b) = 0
Answer: b = 9
Step-by-step explanation:
You should multiply 3 x 3 which will give you 9 than you should subtract it by 9 and that will give you 0 since that is according to your question
Answer:
b = 9
Step-by-step explanation:
3 (3 - b) = 0
9 - b = 0
9 = b
b = 9
How much interest will be earned in a bank account with £3850 that pays 1.3% interest each year how much will there be after 6 years
Answer:
Results are below
Step-by-step explanation:
Giving the following information:
Initial investment (PV)= £3,850
Number of periods (n)= 6 years
Interst rate (i)= 1.3% = 0.013
First, we will calculate the future value (FV), by using the following formula:
FV= PV*(1+i)^n
FV= 3,850*(1.013^6)
FV= £4,160.23
Now, by difference, the interest earned:
Interest earned= 4,160.23 - 3,850= £310.23
