Answer:

im not so sure but i think its a,b,c

Step-by-step explanation:

Answer:

A and C

Step-by-step explanation:

proportional relationships in that situation would be linear and would pass through 0,0.

Answer:

[tex]\sqrt{260}[/tex]

Step-by-step explanation:

a^2 +b^2 = c^2. Since 18 would be c in this equation, you just do 18 squared minus 8 squared.

Answer:

17.89 m

Step-by-step explanation:

A^2+B^2=C^2

8squared=64

18squared=256

64+256=320

320 (radical)

17.89 m

Answer:

e. -490

Step-by-step explanation:

-318+3= -315

-315/9= -35

So that would mean m= -35

-35*14= -490

Answer:

D

Step-by-step explanation:

Let me know if I was right :( don't be mean pls

Answer:

UW = EW+UE=2×EW because, EW=UE

7x-2=2×6= 12

7x=14

x=14/7

x=2

x + 80 = 180 - (64 + 36)

x + 80 = 180 - 100

x + 80 = 80

x = 0

Answer:

the answer is 4.5 but you cannot plant 4 and a half seeds. so the answer would be 3.

Step-by-step explanation:

Answer:

3x + 9

Step-by-step explanation:

You basically want the total amount of seeds so if he plants x in one garden and 2x + 9 in another, you add them both

x + 2x + 9

Equals 3x + 9

Answer:

5/9

Step-by-step explanation: If you find a common denominator ( i found 135 ) and you multiply each numerator by the number u multiplied the denominator to get the common denominator, you can see that 5/9 is greater. hope this helps and sorry if that was confusing

Answer:

5/9 is greater

Step-by-step explanation:

As numerator of second ratio is greater, Hence, 5/9 is greater.

Answer:

[tex]20.25\pi \: {m}^{2} [/tex]

Step-by-step explanation:

[tex]Circumference = 2\pi r = 9\pi \Rightarrow r = 4.5 \\ Area = {r}^{2}\pi = {4.5}^{2} \pi = 20.25\pi[/tex]

Answer:

If you're multiplying them: 34x * 30x = 1020x^2

If you're adding them: 34x + 30x = 64x

If you're subtracting them: 34x - 30x = 4x

Answer:

3 , 11, 25, 45

Diff 8 14 20

Diff 6 6

The second differences are the same. The sequence is quadratic and will contain an n^2 term. The coefficient of n^2 is always half of the second difference. In this example, the second difference is 6. Half of 6 is 3 so the coefficient of n^2 is 3

therefore 3n^2

3 11 25 45

3n^2 3 12 27 48

Remainder 0 -1 -2 -3

Difference -1 -1 -1

linear sequence with nth term -n+1

so nth term of quadratic sequence in 3n^2-n+1

Answer:

B

Step-by-step explanation:

8-5=3, 1-(-7)=8, 3^2+8^2=73, and the square root of 73 is 8.5

Answer:

Step-by-step explanation:

According to sine law of trigonometric functions,

sin(α)/a =sin(β)/b

hence using this

sin(18)/y = sin(x)/2y

sin(x)=2*sin(18)

sin(x)=2*0.309

sin(x)= 0.618

x=sin-1(0.618)     ( sin-1  is sine inverse)

x=38.17 °

Answer:

a.) since he already has 40 in his savings account, start the line at (0,40) on the y-axis and then go up 15 every hour

b.) 15 or 15/1

c.) for each hour Donny spends working, the amount of money he has go up by 15

d.) (0,40)

e.) the vertical intercept or (y-intercept) is (0,40) because this is how much money Donny already has in savings

320 girls & 250 boys

0.2 probability     0.1 probability

320 x 0.2 = 64

250 x 0.1 = 25

64 + 25 = 89

There are approximately 89 students in the school that are left-handed.

Answer

89% of the people are left handed

Step-by-Step Explanation

To find this you have to first do 320 x 0.2

320 x 0.2= 64

To find it for boys you have to do 250 x 0.1.

250 x 0.1= 25

SO, the answer is 89%. 64% of girls and 25% of boys

Hope i helped :D

Answer:

=3a^3−2a^2−a−97

Step-by-step explanation:

THIS IS NOT THE ANSWER, IT'S AN EXAMPLE!!

(You didn't show the numbers that were given for me to answer this. BUT in the example, it shows you how to solve it. Just replace the numbers I put with the ones you were given. If you want me to solve it still, please comment the numbers on this for the answer)

Example; First, write the formula.

A=bh

Next, substitute in the values you have been given.

A=6×2

Then, do the multiplication.

A=12

The answer is 12 sq. cm.

Answer:

x plus 1

Step-by-step explanation:

Answer:

x+1

Step-by-step explanation:

if you simplify the equation, you will get x+1

first, you take the parentheses away.  The equation becomes

3x-2x-4+5

then you combine like terms

x+1

Answer:

1200 inc^3

Length x width x height

10 x 8 x 15= 1200

Answer:

y + 1 = 4/3(x - 9)

Step-by-step explanation:

Point-slope form: y - y₁ = m(x - x₁)

Substitute the numbers into the equation:

y - (-1) = 4/3(x - 9)

y + 1 = 4/3(x - 9)

Answer:

Your correct answer would be 1

Answer:

-3n-2

-3   -3

n=2/3

you would be dividing

it would be N=2/3
