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:

480 in^3

Step-by-step explanation:

4*4*5=80

5*10*8=400

400+80=480

Answer:

480 in^3

Step-by-step explanation:

The volume of the large container is

V = l*w*h = 8*10 *5 = 400 in^3

The volume of the small container is

V = l*w*h = 5*4*4 =80 in^3

Add the volumes together

V = 400+80 = 480 in^3

Answer:

6?

Step-by-step explanation:

did you give the answer in the problem?

Answer:

1.)  Ans  -2 , 14

2.) Ans 2 1/5

3.) Ans y= mx+c

Step-by-step explanation:

first one you use Y = Mx +c

You see the Mx is a multiplication

and you input.

M * x = -5 x 2

M* x = -5 x -1

M* x = -5 x 3

M* x = -5 x -2

and note the answers will be less 4 as the equation states +4 is the y intercept and balances the equation.

So answers of the above in same order are;

-10

5

-15

10

we add 4

-6

9

-11

14

and see that 14 is the correct answer for y.

So the correct coordinates are -2, 14

Question 2) coordinates -1 k can equal = -5x+3

First we write as a division we know the gradient is -5

-we eliminate x

5x-1 / k+3  

= 4x/k+3

M = -5

= 4x = -5(k+3)

= 4x = -5k +15

= 4x -15 =-5k

= -11 =-5k

= 11/-5 = k

k = 2 1/5

3) Ans The equation of a line is y=(input the number whatever times the x to make the number before you add)

y = m

3) Ans then you place x next to it

3) Ans then you place + 4 or whatever adds to the number.

So the equation of the line is what makes y its value through m the gradient being the number you times with x and the difference of that total to make y intercept.

Find y intercept and you have c of  Mx+c

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.

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.

Answer:

4d+56=L

4(39)+56=L

L=212

Step-by-step explanation:

4 miles per day added on to the already existing 56 miles equals the total length.

When subbing in 39 for the number of days (or variable "d" in the equation), and following the order of operations, you get 212 miles of road total at the end of the 39 days.

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.
