Answer:

36.7⁰

Step-by-step explanation:

As the triangle is right angled :

tan of the angle = 24/32

tan of angle = 3/4

angle = 36.9⁰

Answer:

36.9

Step-by-step explanation:

→You use tan since it gives you the opposite and adjacent sides. However, since you're also trying to find the angle measurement, you use the inverse of tan: [tex]tan^-1[/tex]

[tex]tan^-1\frac{24}{32}=?[/tex]

Answer:22 a

23 c

Step-by-step explanation:

:)

Answer:

A

Step-by-step explanation:

Let's first define what exactly the values of a, b, and c represent.

- a: this is the coefficient of the x^2 term

- b: this is the coefficient of the x term

- c: this is the constant term (no variable attached)

Our equation is: y = 7x^2 - 3x + 9.

The coefficient of x^2 is 7, so a = 7. The coefficient of x is -3, so b = -3. And finally, the constant term is 9, so c = 9.

Thus, the answer is A.

Answer:

The general quadratic equation is ax^2 + bx + c = 0

=> Here, we have: 7x^2 - 3x + 9 = 0 <=>  7x^2 + (-3)x + 9 = 0

=> a = 7, b = -3, c = 9

=> Option A is correct.

Hope this helps!

Answer:

Graphs A and C

Step-by-step explanation:

then the line passes through the point (0,-3)

then the line passes through the point (9,0)

and according to the picture ,only in graphs A and C the line C passes through (0,-3) and (9,0)

so the graph solution is either graph A or graph C.

   2. line t : y = -x + 5

then the line passes through the point (0,5)

then the line passes through the point (5,0)

and according to the picture ,only in graphs A and C the line C passes through (0,5) and (5,0).

conclusion:

both graph A and C represent correctly show Lines s and t and the point P

Remark : if you look closely to the graphs A and C ,they are the same thing.

Answer: Graphs A and C

Step-by-step explanation:

Line s : y = 1/3x - 3

for x = 0 → y = 1/3(0) - 3 = 0 - 3 = -3

then the line passes through the point (0,-3)

for x = 9 → y = 1/3(9) - 3 = 3 - 3 = 0

then the line passes through the point (9,0)

and according to the picture ,only in graphs A and C the line C passes through (0,-3) and (9,0)

so the graph solution is either graph A or graph C.

  2. line t : y = -x + 5

for x = 0 → y = -(0) + 5 = 0 + 5 = 5

then the line passes through the point (0,5)

for x = 5 → y = -(5) + 5 = 0

then the line passes through the point (5,0)

and according to the picture ,only in graphs A and C the line C passes through (0,5) and (5,0).

conclusion:

both graph A and C represent correctly show Lines s and t and the point P

Remark : if you look closely to the graphs A and C ,they are the same thing.

Janninne made 68% then 3/25 turned into percentage 12% then 0.2 equals 20%. So you order it by 68% (Janinee), 20% (Kathy), AND 12% (Monique)

Answer:

Setting up the equation you would have: 132 = x + (3x-24)

Now solve for x:

132 = x + (3x-24)

Simplify:

132 = 4x -24

Add 24 to both sides:

156 = 4x

Divide both sides by 4:

x = 156/4

x = 39

Step-by-step explanation:

The measure and equation that should be used is 39 and 132 = x + (3x-24)

Since angle B is x degrees. The exterior angle to angle C is 132 degrees.

Here the equation that should be used is shown below.

132 = x + (3x-24)

132 = 4x -24

156 = 4x

x = 39

Answer:

Step-by-step explanation:

Givens

Accoriding to the given ration, one unit of vertical distance is equivalent to 12 units of horizontal distance. So, the horizontal distance is

[tex]h=12(4 \ in)=48 \ in[/tex]

Therefore, the horizontal distance is 48 inches.

The horizontal distance for a ramp with a 4 inch vertical distance will be 48 inches.

Given,

The height of curb is 4 inches.

We have to calculate the horizontal distance for a ramp with a 4 inch vertical distance.

The ramp from the sidewalk of the street follows the same guidelines as other Ramos, no more than 4.8 degree.

Since The ratio of vertical to horizontal  is 1:12, it means for a 1 inch vertical distance the horizontal distance is 12 inches.

So, for 4 inches of vertical distance the horizontal distance will be,

[tex]12\times4=48[/tex] inches.

Hence the required horizontal distance is 48 inches.
