Help pls this is mad hard

Answer:The slope of a line characterizes the direction of a line. To find the slope, you divide the difference of the y-coordinates of 2 points on a line by the difference of the x-coordinates of those same 2 points.The slope of a line is a measure of its steepness. Mathematically, slope is calculated as "rise over run" (change in y divided by change in x).

Step-by-step explanation:

27,50-24.00=3.50

Answer:

144

Step-by-step explanation:

the 12th square number is

12² = 144

Answer:

50

Step-by-step explanation:

as triangle is =180

then , 30 +100 +x =180

130 +x = 180

x= 180-130

=50

Answer:

50 degrees

Step-by-step explanation:

A triangle is 180 degrees and there is already a 30 and 100.

180-30-100=50.

Step-by-step explanation:

Answer:

Step-by-step explanation:

(+5) + (+2) = +7

If both numbers have same sign, add and the result will have the common sign

v) (-5) + (-2) = (-7)

Both numbers have 'negative sign'. So, add and the result will have the 'negative sign'

Viii) (+6) + (-3) = +3

Both numbers have different sign. So, subtract and the result will have the sign of the bigger number. Here the bigger number is '6' and its sign is 'positive'. so, the result will have positive sign

xi) (-4) + (+8) = +4

Both numbers have different sign. So, subtract and the result will have the sign of the bigger number. Here the bigger number is '8' and its sign is 'positive'. so, the result will have positive sign

Answer:

Step-by-step explanation:

sinθ = 63/√(16² + 63²) = 63/65

cosθ = 16/65

Answer:

Step-by-step explanation:

Use SOH CAH TOA to recall how the trig functions fit on a triangle

SOH: Sin(Ф)= Opp / Hyp

CAH: Cos(Ф)= Adj / Hyp

TOA: Tan(Ф) = Opp / Adj

the above is really helpful if you don't have a brain.  :P

for 7 we only need Pythagoras's theorem, know it?

[tex]c^{2}[/tex] = [tex]a^{2}[/tex] + [tex]b^{2}[/tex]

out of curiosity.. does the above formula seem "impossible" ?  or does it make sense?

[tex]c^{2}[/tex] = [tex]12^{2}[/tex] + [tex]16^{2}[/tex]

[tex]c^{2}[/tex] = 144 + 256

[tex]c^{2}[/tex] = 400

c = [tex]\sqrt{400}[/tex]

c = 20

x= 20

for 8 we do need the above list of trig functions. we want to find the Hyp x and we know an angle and the adjacent side sooo use Cos .. b/c we can see it's got those parts in it

Cos(60) = 18 / x

I'll show you the algebra we need to use to get this formula so that we can find x

A = B / x  ( this is how it looks above )

x = B / A    , now just put in the parts

x = 18 / Cos(60)  now solve it w/ your calculator..  :P Cos(60) happens to be 1/2 so you could have done this w/o your calculator   :/

x = 36

there you go,   :)

Answer:

a = 3, b = 1, c = - 2

Step-by-step explanation:

Substitute n = 1, 2, 3, 4 into the nth term and equate to the values , that is

a + b + c = 2 → (1)

4a + 2b + c = 12 → (2)

9a + 3b + c = 28 → (3)

16a + 4b + c = 50 → (4)

Subtract (1) from (2) to eliminate c

3a + b = 10 → (5)

Subtract (3) from (4) to eliminate c

7a + b = 22 → (6)

Subtract (5) from (6) to eliminate b

4a = 12 ( divide both sides by 4 )

a = 3

Substitute a = 3 into 5) and solve for b

3(3) + b = 10

9 + b = 10 ( subtract 9 from both sides )

b = 1

Substitute a = 3 and b = 1 into (1) and solve for c

3 + 1 + c = 2

4 + c = 2 ( subtract 4 from both sides )

c = - 2

Then

a = 3, b = 1, c = - 2

and y = 3n² + n - 2 ← explicit formula

Answer:

the answer is 3

Step-by-step explanation:

b will be used to determine how many books he bought since he is only buying one movie ticket the equation would be 3b + 10 = 35

Answer:

RECT and ANGL are similar triangles with a ratio of 9:16, and for TR, we have TR:24 in the ratio 9:16 so TR = 13.5

Hope this helps!

Answer:

Step-by-step explanation:

It x=2

Answer:

To do this we just solve for y. Subtract 6x from both sides. Divide both sides by -2. The line has a slope of 3.

Yes

Step-by-step explanation:

10/5 = 2 and 5/5 = 1

Answer:

Yes

Step-by-step explanation:

To find out if the ratios are equivalent you need to simplify both of them. The ratio 2:1 is already simplified all the way. You know this because 2 and 1 have no GCF (greatest common factor) besides 1. However, 10:5 is not all the way simplified. The GCF is 5, so divide both sides by 5. This equals 2:1. The ratio 2:1 is equal to 2:1; therefore, they must be equivalent.

Answer:

39

Step-by-step explanation:

39 because 23 of the students already like hot dogs an 14 like hot dogs and cheeseburgers and 2 like pizza and hot dogs so add them together and you get 39

Answer:

Hat costs 4.00

T-Shirt costs 9.00

Step-by-step explanation:

Let the t-shirt be t and the hat be h

7t+h=67

5t+h=49

Equating by eliminating the h and subtracting

the two equations,

2t=18

t=9.

If t =9 in 5t + h= 49 then

5×9+h=49

45+h=49

h=4

Answer:

24

Step-by-step explanation:

The computation of the number of vertices does one of the base of regular prism is shown below:

V + F = E + 2

V + 14 = 36 + 2

V + 14 = 38

V  = 38 - 14

= 24

Answer:

39°

Step-by-step explanation:

A triangle always equals 180° so you have to subtract the other two angles from 180 to find the measure of J

180°-88°-53°= 39°

Answer:

15

Step-by-step explanation:

You can find this by multiplying the two deniminator numbers. 3*5

Although this dosent always find the lowest deniminator when you are dealing with high numbers, but it will get you an deniminator.
