Can someone help me with the question in the image?

Answer:

720 miles

Step-by-step explanation:

A car uses 8.4 liters of petrol for a 112 mile journey.

In 1 litres = [tex]\dfrac{112}{8.4}\ \text{miles}[/tex] of journey

We need to find far should the car be able to travel on a full tank of petrol i.e. 54 litres of petrol.

[tex]54\ l=\dfrac{112}{8.4}\times 54\\\\=720\ \text{miles}[/tex]

So, the car can travel 720 miles when it holds 54 lirres of petrol.

Answer:

La ecuación simplificada es  [tex]a = \frac{11}{19}[/tex].

Step-by-step explanation:

Tenemos la siguiente ecuación simultánea: [tex]16\cdot a - [3\cdot a - (6-9\cdot a)] = 30\cdot a +[-(3\cdot a+2)-(a+3)][/tex]. El procedimiento consiste en destruir los paréntesis desde dentro hacia fuera, agrupar los términos semejantes y simplificar. Presentamos el proceso paso por paso:

1) [tex]16\cdot a - [3\cdot a - (6-9\cdot a)] = 30\cdot a +[-(3\cdot a+2)-(a+3)][/tex] Dado

2) [tex]16\cdot a -\{3\cdot a + (-1)\cdot [6+(-1)\cdot 9\cdot a]\} = 30\cdot a +\{(-1)\cdot (3\cdot a +2)+(-1)\cdot (a+3)\}[/tex]  [tex]-b = (-1)\cdot b[/tex]

3) [tex]16\cdot a -\{[(-1)\cdot (6)+(-1)\cdot (-1)\cdot 9\cdot a]\}= 30\cdot a +\{\left[(-1)\cdot (3\cdot a) + (-1)\cdot (2)\right] +[(-1)\cdot a +(-1)\cdot (3)] \}[/tex] Propiedad distributiva

4) [tex]16\cdot a -(-6+9\cdot a) = 30\cdot a +(-3\cdot a -2-a-3)[/tex] [tex]-b = (-1)\cdot b[/tex]/ [tex](-b)\cdot (-c) = b\cdot c[/tex]

5) [tex]16\cdot a +(-1)\cdot (-6+9\cdot a) = 30\cdot a -4\cdot a-5[/tex] Propiedad distributiva/Definiciones de adición y sustracción/[tex]-b = (-1)\cdot b[/tex]

6) [tex]16\cdot a +[(-1)\cdot (-6)+(-1)\cdot (9\cdot a)] = 26\cdot a -5[/tex] Propiedad distributiva/Definiciones de adición y sustracción/Propiedad modulativa.

7) [tex]16\cdot a +6-9\cdot a = 26\cdot a - 5[/tex]  [tex]-b = (-1)\cdot b[/tex]/ [tex](-b)\cdot (-c) = b\cdot c[/tex]

8) [tex]7\cdot a +6 = 26\cdot a - 5[/tex] Propiedad distributiva/Definiciones de adición y sustracción.

Answer:

y=1/3x+11/3

Step-by-step explanation:

y=mx+b

y=1/3x+b

3=1/3(-2)+b

3 = -2/3+b

+2/3 +2/3

11/3=b

So the equation of the line that perpendicular to y= -3x + 3/5 that Goes through point (-2, 3 ) is y=1/3x+11/3.

Answer:

72

Step-by-step explanation:

I DIVIEDE 180 DIVIEDED BY $2.50=72

Step 1: We need to determine b by using slope-intercept form, the given slope, and the given line.

[tex]-3 = 2(-4) + b\\\\-3 = -8 + b\\\\5 = b[/tex]

Step 2: Now we create the slope-intercept form for the line.

[tex]y = 2x + 5[/tex]

Step 3: We can now change the above equation to standard form.

[tex]y = 2x + 5\\\\-2x + y = 5\\\\-2x + y - 5 = 0[/tex]

The equation of the line in STANDARD FORM is: D. -2x + y - 5 = 0.

Step-by-step explanation:

Answer:

Sally is 10 miles

The coordinate ofthe deli is (1, -1)

Step-by-step explanation:

✍️Coordinate of Sally = (-3, 2)

Coordinate of Ocean Front = (5, -4)

The distance of Sally to Ocean Front Housing Complex = the distance between point (-3, 2) and (5, -4).

Use the distance formula, [tex] d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} [/tex], to calculate the distance between (-3, 2) and (5, -4):

[tex] d = \sqrt{(5 -(-3))^2 + (-4 - 2)^2} [/tex]

[tex] d = \sqrt{(8)^2 + (-6)^2} [/tex]

[tex] d = \sqrt{64 + 36} [/tex]

[tex] d = \sqrt{100} = 10 [/tex]

✅The distance of Sally is 10 miles

✍️the coordinate of Deli would be half the distance between Sally and Ocean Front.

Therefore, use the midpoint formula to calculate the coordinate of the midpoint between Sally (-3, 2) and Ocean Front (5, -4).

Midpoint of (-3, 2) and (5, -4).

[tex] M(\frac{x_1 + x_2}{2}, \frac{y_1 + y_2}{2}) [/tex]

Plug in the values

[tex] M(\frac{-3 + 5}{2}, \frac{2 +(-4)}{2}) [/tex]

[tex] M(\frac{2}{2}, \frac{-2}{2}) [/tex]

[tex] M(1, -1) [/tex]

✅The coordinate ofthe deli is (1, -1)

3000 people

Step-by-step explanation:

4% teenagers --> 120 teenagers were there

120/4 means 1% so 30 is 1%

1% times 100 is 100% so 30 times 100 equals 100% so 3000 is 100% of the people at the stadium

Step-by-step explanation:

First I formed the equation 10.4-16.7=x, which the answer came to be -6.3 degrees.

Answer:

sqrt10

Step-by-step explanation:

Since the closest distance between two parallel lines is a line that is perpindicular to them, we first find the line of the slope that is perpindicular to both lines. Since slope of line y = 3x+10 is 3, the slope of the line that is perpinduclar is -1/3. Therefore y = -1/3x is perpindicluar to both lines. We then find the intersection point of each line. We find said points by setting the lines equal to each other. 3x+10=-1/3x, x = -3 therefore y = 1. For the second line we get we find the origin is the intersection. Therefore since this forms a right triangle with the x axis, we find that the distance is 3^2+1^2 = sqrt10

Answer:

6

Step-by-step explanation:

what you do is because you are dividing -4 by -2/3 you have to flip -2/3 to make it -3/2..

so ...

-4/ -2/3 = -4 x -3/2  ( so here you take -2/3 and flip it and multiply by -4)

now all you do is multiply

12/2 you get 6 ! HOPE this helped out alittle

Answer:

The second band

Step-by-step explanation:

50+20=70

20+25=45

To find the exact difference, we have to subtract the two decimal points.

1. First, we'll subtract the whole number. Then, we'll subtract the decimal number. This will make mental math easier.

a. 7 - 3 = 4

b. 8 - 2 = 6

2. Add the answers together to get your final answer.

a. = 4.6

The exact distance between the two points is 4.6. If you can't figure this strategy out, do algorithm. The simplist way to solve this is to use a calculator, which I checked my answer on. Have a nice day! :)
