The price of an oven was increased by 20% to £156.
What was the price before the increase?​

Answers

Answer 1

Answer:

Step-by-step explanation:

Before the increase it was 100%

So 20+100=120

156/120*100=130$

Don’t do it like 20/100 *156 and then minus it from 156 because you will get a wrong answer

(This was answered by another person on a another question.)

Answer 2

Answer:

130

Step-by-step explanation:

x * 1.2 = 156

x = 156/1.2

x = 130

The mean marks of 100 students were calculated as 65. At the time of checking it was found the marks 40 and 50 was wrongly copied and weeded out Find the correct mean marks.​

Answers

Answer:

[ Because those two numbers are removed you need to reduce the number of terms to 98. ]

☆Solution☆

N=100

Mean=65

(Wrong Numbers=40,50)

Now,

Mean=Sum/No. of items

or,65=Sum/100

▪Sum=65×100=6500

After removing the unnecessary numbers,

New Sum=6500-40-50=6410

New no.of terms(N)=100-2=98

Now,

New Mean=New Sum/New N

=6410/98

=65.41

A. ( -3, 4) , ( -4, 3 ) , ( -4, 1 ) , ( -2, -4 )

Answers

Answer:

B

Step-by-step explanation:

There isn't really much explaining I can do but each time you find the co-ordinate of a point you can cancel out a possibility.

For example, one of the points is (-3,4) and the only one without this point is C so that answer is cancelled out, and you keep going this way until you are left with only on possible answer and that should be B.

Top left = (-3,4)

Bottom left = (-2, -4)

Top right = (3,4)

Bottom right = (1,-4)

The answer is B.

(-3,4) is the point/dot on the top left corner.

(3,4) is the point on the top right corner.

(1,-4) is the point on the bottom right corner.

(-2,-4) is the point on the bottom left corner.

2. Write two numbers that are opposites and each more than 6 units away from 0.

Answers

Answer:

-7, 7

Step-by-step explanation:

Opposites are basically two numbers that are at different sides of the number line. For example, -2 and 2 are opposites because they are the same distance away from 0 on a number line making them opposites. To make an opposite just take a positive number, and then add a negative to it. (8, -8)

12, 17, 22... find the 35th term

Answers

Answer:

a₃₅ = 182

Step-by-step explanation:

There is a common difference d between consecutive terms, that is

d = 17 - 12 = 22 - 17 = 5

This indicates the sequence is arithmetic with n th term

[tex]a_{n}[/tex] = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 12 and d = 5 , then

a₃₅ = 12 + (34 × 5) = 12 + 170 = 182

Step-by-step explanation:

Y-intercept can be read off the graph.

Slope can be determined using the formula:

y2-y1 divided by x2-x1 (Substitute co-ordinates)

Answer:

y=2x-3

Step-by-step explanation:

y=mx+b

Where m is the slope and b is the y intercept

Slope is rise over run, the line is up 2 over 1

And the point of the line where it meets the y axis is -3. so b is -3
