HELP WITH MY MATH EXAM i don't know what to do and my head hurts a lot

Answer:

a) 98m

b) 2m/s

Step-by-step explanation:

a) 2+4+6+8+10(8) = 98m

b) a = change/time = 8m/4s = 2m/s

not completely sure about a) so pls double check that <//3

good luck and hope this helped a bit!

The correct answers for the given problem are: (a) The distance travelled on the cycle in the first 14 seconds is 96 m and (b)The acceleration in the first 4 seconds is 2 m/s².

The area under a graph can be found by dividing the graph into equal intervals of very small width and then find the area of the rectangle for each intervals. After summing all the areas of rectangles the area under the graph can be approximated.

The velocity time graph given in the problem can be used to find the distance travelled.

The distance travelled in first 14 seconds is equal to the area of the graph from t = 0 to t = 14.

This area consists of a triangle of height h = 8 and base b = 4 and a rectangle of length l = 8 and width b = (14 - 4) = 10.

Now, the total area is given as,

1/2 × b × h + l × b

= 1/2 × 4 × 8 + 8 × 10

= 16 + 80

= 96

(b) The acceleration is given as the rate change of velocity with respect to time.

The acceleration in first 4 seconds is given as,

a = (8 - 0)/4

   = 2

Hence, the distance travelled in first 14 seconds and acceleration in first 4 seconds is given as 96 m and 2 m/s² respectively.

Answer/explanation:

Given:

m<8 = 23°

a. m<1 = 180° - m<8 (corresponding angles theorem and supplementary angles theorem)

m<1 = 180 - 23 = 157°

b. m<2 + m<1 = 180° (linear pair)

m<2 + 157° = 180°

m<2 = 180° - 153° = 23°

c. m<3 = m<1 (vertical angles are congruent)

m<3 = 157°

d. m<4 = m<2 (vertical angles are congruent)

m<4 = 23°

e. m<5 = m<1 (corresponding angles)

m<5 = 157°

f. m<6 = m<8 (vertical angles are congruent)

m<6 = 23°

g. m<7 = m<5 (vertical angles are congruent)

m<7 = 157°

Answer:

y= -2/3x + 4

Step-by-step explanation:

2x + 3y = 12

3y = 12 - 2x

3y/3 = 12/3 - 2x/3

y = 4 -2x/3

y = -2x/3 + 4

Answer:

Answer:

(5, 20)  

Step-by-step explanation:

We can find the slope of the line

m = (y2-y1)/(x2-x1)

   = (40-0)/(10-0)

   = 40/10

   =4

Since the line goes through (0,0) the y intercept is 0

y = mx+b

y = 4x

Lets check the points  by substituting into the equation

40, 10)     10 = 4*40   10 =160  no

(–5, –10)    -10 = 4*-5    10 = -20   no

(5, 20)       20 = 4*5    20 = 20  yes

(–10, –20)    -20 = 4*-10    -20 = -40   no

Step-by-step explanation:

Which ordered pair would form a proportional relationship with the point graphed below? On a coordinate plane, a line with negative slope goes through points (negative 20, 10), (0, 0), and (20, negative 10). (10, –20) (–30, 20) (–10, 5) (35, –20)

c

Step-by-step explanation:

egde2020

y = -2x + 3

y = -x + 10

y = 4x + 10

y = 3/2x - 2

y = -1/2x - 1

y = x + 5

y = 25x + 5

y = .99x + 1.99

y = x - 2

y = -1.50 + 1.50

y = 42x + 27

y = -1/3x - 2

Answer:If you rotate trapezoid BEFG counter clockwise 90° then reflected across pointy you will have the image above

Step-by-step explanation:

Transformation involves changing the position of a shape

The transformation from T to T' is a 90 degree counterclockwise

From the figure, we can see that:

This means that:

A 90 degree counterclockwise through point D will take trapezoid T to T'

Hence, the required transformation is a 90 degree counterclockwise through point D

Answer:

The volume, in cubic feet, of the larger rectangular prism is 64 cubic feet

Step-by-step explanation:

Length of small cube =[tex]\frac{1}{2} ft[/tex]

Volume of each cube = Side^3

Volume of each cube =[tex](\frac{1}{2})^3[/tex]

                                    =[tex]\frac{1}{8} ft^3[/tex]

Volume of 64 cubes = [tex]64 \times \frac{1}{8}[/tex]

Volume of 64 cubes [tex]= 8 ft^3[/tex]

We are given that He uses all the cubes to fill a box shaped like a larger rectangular prism.

So, Volume of 64 cubes = Volume of rectangular prism

So, If there are 64 of these cubes in the larger prism, then the volume, in cubic feet, of the larger rectangular prism is 64 cubic feet

Answer:

La cantidad de boletos vendidos en la sección numerada = x = 4000 boletos

El número de entradas vendidas en la sección general = y = 8000 boletos

Step-by-step explanation:

Deje que el número de boletos vendidos en la sección numerada = x

Sea el número de boletos vendidos en la sección general = y

Es un partido de fútbol sala se vendieron 12.000 entradas.

x + y = 12000.… ..... Ecuación 1

x = 12000 - y

El precio de las entradas es de $ 25.00 en la sección numerada y $ 15.00 en la general. Si el ingreso total obtenido fue de $ 220,000.00,

$ 25 × x + $ 15 × y = $ 220 000

25x + 15y = 220.000 ..... Ecuación 2

Sustituya x por 12000 - y en la ecuación 2

25 (12 000 - años) + 15 años = 220 000

300000 - 25 años + 15 años = 220 000

300000 - 220000 = 25 años - 15 años

80000 = 10 años

y = 80000/10

y = 8000 boletos

x = 12000 - y

x = 12000 - 8000

x = 4000 boletos

La cantidad de boletos vendidos en la sección numerada = x = 4000 boletos

El número de entradas vendidas en la sección general = y = 8000 boletos

Responder:

8000

Explicación paso a paso:

Dado que las entradas:

Sección numerada = $ 25

Sección general = $ 15

Ingreso tital = 220.000

Número de entradas vendidas = 12000

Deje el boleto vendido de la sección numerada = n

Número vendido de la sección General = g

n + g = 12000

25n + 15g = 220.000

n = 12000 - g

25 (12000 g) + 15 g = 220000

300.000 - 25g + 15g = 220000

-10g = 220000 - 300000

-10g = - 80000

g = 8000

n = 12000 - g

n = 12000 - 8000

n = 4000

Entradas vendidas de la sección General = 8000
