If 10 litres of petrol cost 17.10$, calculate the cost of 4 litres of petrol?​

Answer:

D

Step-by-step explanation:

all answers are x = 0. If we put 0 instead of X.

y=0^4+3×0^3-2×0+7

y=0+0+0+7

y=7

Answer:

No solution.

Step-by-step explanation:

Answer:

Step-by-step explanation:

1. Slope

2. Hypotenuse

In order to find out what g is equal too,u must subtract 19 from both sides of the equation to get

g +19-19=38-19

the nineteens cancel out getting

g=38 -19

g=19

Answer:

5.6

Step-by-step explanation:

The equation is put in y = mx + b

where m = slope ( rate of change ) and b = y intercept

5.6 = m and 7 = b

Hence the rate of change for y = 5.6x + 7 is 5.6

Answer:

96

Step-by-step explanation:

once you fill in the Blanks that are solvable, you will work your way into the answer. For example, the first column, the missing number has to be 155-76 or 79. Now you can find your answer. In the second row, “no Laptop”, you have 79 (solved above) plus 17. So your answer is 79+17 or 96.

Answer:

Area of Rectangle = 28 cm²

Step-by-step explanation:

Given - A rectangle has coordinates (2, 6) (9, 6) (9, 10) and (2, 10) on a grid with 1 cm squares.

To find - What is the area of the shaded rectangle?

Solution -

The graph of the rectangle is as follows :

From the diagram, e can see that

Length of Rectangle = 7 units (cm)

Breadth of Rectangle = 4 units (cm)

We know that,

Area of Rectangle = Length × Breadth

                              = 7 × 4

                              = 28 cm²

⇒Area of Rectangle = 28 cm²

Answer:

Component Form: v = <-1,6>

Magnitude of v: ||v|| = √37

Direction of v: θv = 100° (to the nearest degree)

Step-by-step explanation:

Component Form: v = <(5-6),(3-(-3))> = <-1,6>

Magnitude of v: ||v|| = √[(-1)²+(6)²] = √(1+36) = √37

Direction of v: α = tan⁻¹|6/-1| = tan⁻¹|-6| = tan⁻¹(6) = 80.53° which is your reference angle, but to verify that the angle is in the second quadrant, you'll need to do θv = 180° - 80.53° = 99.47°, therefore your direction angle is θv=100° to the nearest degree.

Answer:

a Answers is A

b Answer is D

Step-by-step explanation:

he sayed that the X doubles in the first one so its ×2

and in the second one he sayed that the x is only triples so we dont have to Multiply we have to devide it 5/x/3=5/x ×1/3

Answer:

Step-by-step explanation:

3x + 4y = 17

5x - 4y = 7

you can thus cancel out 4y

Hence

8x = 24

Hence x = 3

Substituting’

3(3) + 4y = 17

9 + 4y = 17

Hence 17 - 9/4

= y = 2

Answer:

448 yd^3

Step-by-step explanation:

V = Bh  where B is l * w

V = l*w*h

V = 8* 14* 4

  =448 yd^3

Answer:

The volume of this rectangular prism is equal to [tex]448yd^{3}[/tex].

Step-by-step explanation:

From the question, we know the formula for the volume of a rectangular prism is V = Bh (where B is length times width, and "h" is the height).

Now we replace B (because we know that B is length times width) and get...

V = lwh (where "l" is the length of the prism, and "w" is the width of the prism.

Now we just substitute the values and get...

[tex]V = lwh = (14)(4)(8) = 448yd^{3}[/tex]

Answer:

19329, you are correct

Step-by-step explanation:

Volume = [tex]\pi * r^{2} * h[/tex]

Volume = [tex]3.14 * (18)^{2} *19[/tex]

Volume= 19329.84

not rounded= 19329

Answer:

y= -3/2X + 2

Step-by-step explanation:

we get the gradient by picking any two points from the graph( it a linear graph)

using the point:

(x,y)= (-2,5) , (4,-4)

using M= (y2-y1)/x2-x1)

we get our gradient to be -9/6 which is

-3/2

using the equation of a straight line graph which is

y-y1=m(x-x1) and the point (4,-4)

we get

y-(-4)=-3/2(x-4)

----> y+4= -3/2x + 6

make y subject of the formula to take the form

y=mx+c

we get :

y=-3/2x + 2

Answer:

81 un²

Step-by-step explanation:

9 · 7 = 63 un²

(b · h) ÷ 2

(5 · 4) ÷ 2 = 10 un²

(4 · 4) ÷ 2 = 8 un²

8 un² + 10 un² + 63 un²

81 un²

Answer:

81 un^2

Step-by-step explanation:

Find area of the rectangle. 9 x 7 = 63

Find area of the triangle. 9 x 4 = 36/2=18

63 + 18 = 81
