How much petrol is needed to travel 120 km?

Answers

Answer 1

Answer:

9 litres

Step-by-step explanation:

200 = 15

divide both sides by 200

1 = 0.075

we know that the measure of the out side angle is equal to the measure of the 2 inside angles, so 120-50=70

Answer:

∠ U = 70°

Step-by-step explanation:

the exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

∠ RVU is an exterior angle of the triangle , then

∠ U + 50° = 120° ( subtract 50° from both sides )

What is the gradient of 2y=4x+6

Answers

Answer:

The answer is 2.Divide each side by 2

Simplify : y = 2x + 3

Replace x = 1 -> y = 5

We will draw a line that goes through the point 1 on the x axis, and point 5 on the y axis (cant draw right now, sorry xd)

(Now, you can find the gradient by simply forming a right triangle with the hypotenuse being the line itself, but i will use the slope to save time)

We will select 2 points : (1;0) and (0;5)

Replace it into m = [tex]\frac{y2-y1}{x2-x1}[/tex] = [tex]\frac{5-0}{0-1} = -5[/tex]

Based on the percentages given on those who visited the Great Wall, the relative frequencies will show the following?

People who visited Great Wall - 170 people.People who visited the Chengdu Panda Center - 51 people.People who visited Panda Center - 24 people.

How many people visited the Great Wall?

The number of people who went to Great Wall was:

Charlotte has a large container of only red beads.
Harry has a large container of only blue beads.
Charlotte and Harry swap 40 beads.
This means that Charlotte gets 40 of Harry's blue beads in her container and Harry gets 40 of Charlotte's red beads in his container.
Charlotte now randomly picks 90 beads from her container and notices that 9 are blue.
Harry now randomly picks 80 beads from his container and notices that 70 are blue.
If all the beads were placed in one container, work out an estimate for the ratio of red to blue beads.
Simplify your answer fully.

Answers

Using it's concept, it is fond that the estimate for the ratio of red to blue beads is of 91:79.

What is the ratio between two amounts?

The ratio between two amounts a and b is given by a divided by b, that is:

[tex]\frac{a}{b} = a:b[/tex]

In this problem, considering Charlotte's and Harry's beads, there are 81 + 10 = 91 red beads and 9 + 70 = 79 blue beads, hence the ratio is given by:

I don't understand this
the box is in the shape of a cuboid.
height: 60cm
length: 100cm
width: 40cm
Joh wants to fill the box with grit.
A bag of grit costs £2.50
there are 8000cm^3 of grit in a bag.
Joh has £70 to spend on the grit.
Does John have enough money to buy all the grit he needs to fill the box completely?

Answers

We calculate the volume of the cuboid :

60 x 100 x 40 = 240000 cm^3

If every bag has 8000 cm^3 of grit, he will need 240000 : 8000 = 30 bags

Every bag cost £2.50, so he will need £2.50 x 30 = £75

Since he only has £70, he doesn't have enough money to buy the grit.

can someone please help me with Arithmetic Sequences

Answers

Answer:

287

Step-by-step explanation:

Sum of A Finite Arithmetic Sequnece is

[tex] \frac{a _{1} + a _{n} }{2} n[/tex]

Where a1 is first term

an is final term

N is the number of terms.

We know a1 is 1

An is 40 but we don't know n.

To find n, we use the definition of a Arithmetic Sequence

[tex]a _{n} = a + (n - 1)d[/tex]

where d is the common difference. Let use the final term, 40 as a example.

Here the common difference is 3 so we have

[tex]40= 1 + (n - 1)3[/tex]

[tex]39 = 3(n - 1)[/tex]

[tex]13 = n - 1[/tex]

[tex]14 = n[/tex]

So we have 14 terms in this finite series.

Now we compute

[tex] \frac{1 + 40 }{2}(14) = \frac{41}{2} (14) = 41 \times 7 = 287[/tex]

So the answer is 287

Match the steps to solve the following equation using distributive property. 4 (2x - 6) = 24

Answers

Answer:

1) 8x - 24 = 24

2) 8x - 24 + 24 = 24 + 24

3) 8x = 48

4) x = 6

Step-by-step explanation:

Bolded are the answer choices:

4(2x - 6) = 24

First, distribute 4 to all terms within the parenthesis:

4(2x - 6) = 24

(4 * 2x) - (4 * 6)

(8x) - (24) = 24

8x - 24 = 24.

Next, add 24 to both sides of the equations:

8x - 24 (+24) = 24 (+24)

8x = 24 + 24

8x = 48

8x - 24 + 24 = 24 + 24

Then, divide 8 from both sides of the equation:

(8x)/8 = (48)/8

x = 48/8 = 6

8x = 48

x = 6
