Answer:

12.5 minutes

Step-by-step explanation:

Just divide 25 by 3 to get 12.5

Answer:

37.5 minutes

Step-by-step explanation:

We can set a ratio to model this problem

It takes Jacob 25 minutes to line 2/3 of the flag football field.

The ratio here is 25 : 2/3.

We want to figure out what x : 1 is.

25 : 2/3

x : 1

We can model this by fractions:

[tex]\frac{25}{\frac{2}{3}} = x[/tex]

When you divide by a fraction, you end up multiplying it by the reciprocal.

[tex]25(\frac{3}{2})=x[/tex]

[tex]x=\frac{75}{2}[/tex]

[tex]x = 37.5[/tex]

LCD needed to combine the variables:  15

LCD needed to combine the constants:  21

==============================================

Explanation:

If two numbers m and n do not have any common factors (other than 1), then the LCM is m*n. We simply multiply the values.

So for example, the LCM of 2 and 3 is 2*3 = 6.

For the variable terms, the denominators are 5 and 3. So the LCM is 5*3 = 15, and this is the LCD of those variable fractions.

Similarly, the LCD of the constant terms is 21 because 7*3 = 21.

--------

Again, for all of these examples, the two values had no factors other than 1 in common. If you were dealing with something like the LCM of 8 and 12, then the LCM would not be 8*12 = 96. But we can fix things by dividing that by 4 to get 96/4 = 24 which is the true LCM here.

So the more generalized formula would be (m*n)/(GCF of m and n)

This formula works for the previous section because the GCF was 1.

Lo que queremos hacer es mover la figura 6 unidades a la izquierda, y 5 unidades hacia abajo.

Para hacer esto, simplemente podemos tomar cada vértice de la figura y moverlo 5 unidades hacia abajo, y luego 6 unidades a la izquierda.

Una vez hemos movido los 4 vértices, podemos conectarlos con segmentos, y de esta forma tendremos la figura trasladada.

En la segunda imagen se puede ver como este proceso se hace para el vértice derecho de la base. En el mismo gráfico se movieron los otros 3 vértices y se conectaron, para así obtener la figura trasladada.

Answer:

2.02 m

or 2 m 2 cm

Step-by-step explanation:

Imagine a triangle containing the 40° angle and that this angle is at the left.  Then the height of the truck bed is 1.3 m and the "shortest possible length of the ramp" is the hypotenuse of this triangle.  We need to find the length of this ramp, that is, the length of the hypotenuse.  

The sine function relates this 40° angle and the 1.3 m height of the truck bed:

sin 40° = opp / hyp = 1.3 m / hyp

which can be solved for 'hyp' as follows:

              1.3 m

hyp = ----------------- = (1.3 m) / 0.6428)

             sin 40°

                                                                                  1.3 m

Thus, the length of the ramp must be less than -------------- or 2.02 m

                                                                                 0.6428

where this last result is to the nearest cm.

If the ramp is shorter the angle of the ramp will be smaller and the ramp angle considered safer.

I thing it lies on the negativity side of the number line between -2,24

Answer:

No, more information is needed to prove that Amy will get to school first.

Step-by-step explanation:

Even though Amy is traveling at a faster rate than Jeremy, the problem does not say how far away Amy's father's or Jeremy's aunt's houses are from the school.  

Answer:

Step-by-step explanation:

No, the rate with the greater positive rate of change will not necessarily reach the output with the smallest input. The initial value will also affect the outcome. Although Amy is biking at a faster rate of change, Jeremy might get to school before her if his aunt lives closer to the school than her father does.

Answer:

I cannot read it

Step-by-step explanation:

Step-by-step explanation:

the answer should be the first option bcos

when we use the table of values

let's just assume the values of x to be 0,1,2and3

so when x= 0

using the given formula y=2x-3

we get

y= 2(0)-3

=0-3

= -3

so we have x=0,y=-3

we do the same for the rest of the values

y=2(1)-3=2-3 =-1

y=2(2)-3=4-3= 1

and on the gragh this gives a straight line

where the values of y are -3,-1,1

and x are 0,1,2

Answer:

29.1°

Step-by-step explanation:

Given that :

Riser, AB, Opposite = 10 cm

Thread, = AC, Adjacent = 18 cm

Angle of inclination, θ

Using trigonometry :

Tan θ = opposite / Adjacent = AB / AC

Tan θ = 10 / 18

θ = tan^-1(10/18)

θ = 29.055

Hence, angle of inclination is 29.1° (1 decimal place)

A starts off increasing so it cannot be it

B is increasing after some point, so doesn't work

C works

D has a constant y after some point, so doesn't work (not increasing or decreasing)

therefore: C is the correct answer

Answer:

A. quadratic; y = 2.5x2

Step-by-step explanation:

Answer:

Option (1)

Step-by-step explanation:

x               -2              -1                 0                    1                   2

y               10            2.5                0                  2.5                3.0

Ist difference,

    = -2.5

   = 2.5

   = 7.5

2nd difference,

    = 5

   = 5

   = 5

Since 2nd difference is common, given table represents a quadratic equation.

Let the equation is,

y = ax²+ bx + c

For a point (0, 0) passing through the quadratic equation,

0 = c

Therefore, quadratic equation is y = ax² + bx

Since ordered pair (-1, 2.5) passes through the graph of the function,

2.5 = a(-1)² + b(-1)

a - b = 2.5 ------(1)

For another point (1, 2.5)

2.5 = a(1)² + b(1)

a + b = 2.5 ------(2)

By adding equations (1) and (2),

2a = 5

a = 2.5

and from equation (2)→ y = 0

Therefore, equation of the quadratic function given in the table is y = 2.5x²

Option (1) is the answer.

Answer:

B

Step-by-step explanation:

The perpendicular is sin(43)*39=21.82. Next tan(32)=x/21.82. x=21.82*tan(32)=13.6

The value of x in the given question is 16.6

A right angle triangle has 3 sides opposite is the side opposite to the angle formed by two adjacent sides.hypotenuse is the largest side and adjacent is the remaining side.

Assuming height of the triangle = y

Sin∅ = opposite/hypotenuse

sin43° = y/39

y= 39sin43°

y = 26.6
From this we will solve the value of x

tan∅ = opposite/adjacent

here adjacent = 26.6 and opposite = x

tan32° = x/26.6

x = 26.6tan32°

x = 16.6

Answer:

y = 4/3x+2/3

Step-by-step explanation:

the 2 coordinates provided are: (4,6) and (-5,-6)

y=mx+c

m= (y1-y2)/(x1-x2) = (-6-6)/(-5-4) = 4/3

sub x = 4, y = 6

6 = 4/3 * 4 + c

c = 2/3

Answer:

y = 4/3x+2/3

Step-by-step explanation:

Pick two points on the line to find the slope

(-5,-6) and (4,6)

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

m = ( 6 - -6)/( 4 - -5)

   = ( 6+6)/(4+5)

   = 12/9

  = 4/3

The slope intercept form of a line is y =mx+b where m is the slope and b is the y intercept

y = 4/3x+b

Substitute a point into the equation

6 = 4/3(4)+b

6 = 16/3+b

Subtract 16/3 from each side

18/3 - 16/3 =b

2/3 = b

y = 4/3x+2/3  

Answer:

22.2 m.

Step-by-step explanation:

They walk in a right triangle.

First they walk 7 then 6 m = 13 m.

We calculate the distance of the diagonal using Pythagoras:

x^2 = 6^2 + 7^2 = 85

x = √85

Probability is just the amount of the specified object over the total amount of objects.

Amount of Red : 2

Amount of Orange: 5

Amount of Green: 3

Amount of Brown: 4

Total: 14

*Formula: (Specified Object)/(Total)*

F) Chances of Red or Orange or Green
