Can anybody help me please hurry

Answer:

$30 or 60%

Step-by-step explanation:

20 ×4= 80

80-50= 30

30/50= .6 , or 60%

Answer:

30°,45° and 55° cant exist

Step-by-step explanation:

30 + 45 + 55= 130

a triangle must have 180°

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

Answer:

918

Step-by-step explanation:

Given data

Initila population= 85

Rate = 12%

TIme= 21 years

Let us apply the compounding expression

A=P(1+r)^t

substitute

A= 85(1+0.12)^21

A=85(1.12)^21

A=85*10.80

A= 918

Hence the approximate Rabbit population will be 918

Answer: I don't know if this would be helpful, but in this case, you can really just move the decimal point to the right the amount of times you see a zero in what you are multiplying it by. 1.86 x 10 = 18.6 , 1.86 x 100 = 186

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

Nearest Thousand is: 8,651, so rounding to it would be 9,000.

Answer:

9,000 is the nearest thousand

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°

Step-by-step explanation:

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!

Answer:

66

Step-by-step explanation:

Answer:

true

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.

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.

Answer:

C. 7/8

Step-by-step explanation:

3 1/2 = 3.5 and she picked 1/4 of that number. I divided 3.5 by 4 and got 0.875. I then turned that into fraction form for 7/8.

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

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

Its been awhile but i think its y=0x+5

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

Answer:

Solution → (2, -1)

Step-by-step explanation:

Input-output values table for equation (1),

2x + y = 3

x          -1          0         1         2          

y          5          3         1         -1

Input-output values table for equation (2),

y = x - 3

x         -1          0         1         2  

y         -4        -3        -2        -1

Now plot these points to get the graphs of both the equations.

Common point (2, -1) of both the lines will be the solution of the system of equations.
