Susan got 72 marks in English out of 120 and 70 marks in
Hindi out of 150. The maximum marks in the mathematics
paper were 180. If she got 60% marks in all the three papers
how y marks did she get in mathematics?​

Answers

Answer 1

Answer:

let the marks obtained in maths be x

total marks obtained by susan=142+x

then

A/Q

60%of 450 =(142+x)

270=142+x

x=270-142

x=128

hence marks obtained in maths=128

OR

Max marks 120+150+180=450

60% of 450 is 270

70 +72+x=270

x=270-142

x=128

Question 8 (4 points) Find the values of x and y if NO = x + 2y, MO = 3x, PQ = 6x + 4, and OQ = 2y + 4.

Answers

Answer:

x = 12 and y = 16

Step-by-step explanation:

Given the following lengths;

NO = x + 2y,

MO = 3x,

PQ = 6x + 4, and

OQ = 2y + 4.

The following postulates are true;

MN = PQ

Since MO + ON = MN

MN = 3x + x+2y

MN = 4x + 2y

Recall that PQ = 6x+4

Equating both expressions;

4x + 2y=  6x+4

Collect like terms;

4x-6x + 2y = 4

-2x + 2y = 4

x - y = -4 ...... 1

Also MO = OQ

3x =  2y + 4

3x-2y= 4 ....2

from 1; x = -4 + y

Substitute into 2:

3x-2y= 4

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

-12+3y-2y = 4

-12+y = 4

y = 4 + 12

y = 16

Since x = -4+y

x = -4 + 16

x = 12

Hence x = 12 and y = 16

Eileen collected 78 empty cans to recycle, and Carl collected 62 cans. They packed an equal number of cans into each of seven boxes to take to the recycling center. How many cans were in each box?

Answers

Answer:

20 cans

Step-by-step explanation:

Eileen collected 78 empty cans to recycle

Carl collected 62 empty cans to recycle

They pack equal number of cans in 7 boxes

Therefore the number of cans in each boxes can be calculated as follows.

= 62 + 78/7

= 140/7

= 20

Hence there were 20 cans in each boxes

Work out the equation of the line which has a gradient of 3 and
passes through the point (-2, 4).​

Answers

Answer:

y=3x+10

Step-by-step explanation:

We can use standard form to write the equation of this line.

y=mx+b

where m=the slope (or gradient) of the line

and where b= the y-intercept

now to solve...

we know the slope (gradient) or m=3

so we can put this in the equation.

y=3x+b

now we must solve for b.

in order to this we can subsitute the coordinate (-2,4) into x and y since

a coordinates values/variable representation is (x,y) -> (-2,4)

So subsituting the coordinate in...

y=3x+b

4=3(-2)+b

simplify.

4=-6+b

b=10

This means the y-intercept=10

so...

y=3x+10

is the equation of the line.

Answers

Answer:

Explanation:

To evaluate the expression (60−6)×(13)3+27÷3 we use BODMAS

BODMAS is an acronym/rule in mathematics that dictates the order we should solve mathematical operations such as the above.

BODMAS stands for bracket first, order or of, division, multiplication, addition and then lastly subtraction

To solve the expression using BODMAS, we solve the brackets first

(60−6)×(13)3+27÷3 =54×39+27/3

Then division

=54×39+9

=2106+9

Then addition

=2106+9=2115

Which ordered pair is a solution of the equation y+1=3(x-4)

Answers

Step-by-step explanation:

When x = 4 and y = -1,

(-1) + 1 = 3(4 - 4) = 0.

Hence (4, -1) is an ordered pair.

When x = 5 and y = 2,

(2) + 1 = 3(5 - 4) = 3.

Hence (5, 2) is an ordered pair.

Therefore the answer is C.

simplify this Problem 1.5 x 1.5

Answers

Answer:

2.25

Step-by-step explanation:

1.5 times 1.5 is 2.25

"simplify" just means to solve in ur case..

Hope this helps!!

1.5 multiplied by 1.5 equals 2.25.

To simplify the problem 1.5 x 1.5, you can multiply the two numbers together.

To calculate this, you can follow these steps:

Multiply the first digit of the first number (1) by the first digit of the second number (also 1): 1 x 1 = 1.

Multiply the decimal parts of both numbers: 0.5 x 0.5 = 0.25.

Add the results from step 1 and step 2 together: 1 + 0.25 = 1.25.

The final answer is 1.25, but we need to consider the decimal places. Since both numbers have one decimal place, the final answer will have two decimal places: 2.25.

Therefore, 1.5 x 1.5 simplifies to 2.25.

The 600 mile, Texas Gulf Coast has various barrier islands that protect the coast from storms. If each barrier island is an average of 75 miles in length, how many barrier islands are there?

Answers

Answer: 8 barrier island.

Step-by-step explanation:

From the question, we are informed that Texas Gulf Coast is about 600 miles and that it has various barrier islands that helps protect the coast from storms.

We are further told that each barrier island is an average of 75 miles in length. Therefore, the number of barrier islands that are there will be gotten by dividing 600 by 75. This will be:

= 600 / 75

= 8 barrier island

Colton is about to ride a straight water slide. The launching platform is at the top of a tower that is 8 meters tall. The splash pool at the end of the slide is 15 meters from the base of the tower. How long is the water slide itself? Show your work.

Answers

Answer:

The length of the water slide itself is 17 meters

Step-by-step explanation:

Here, we want to calculate the length of the water slide

from the description given in the question;

we have a right angled triangle where the height of the tower, the distance from the base of the tower and the length of the slide itself represents the sides of the triangle

From the description given in the question, the water slide length represents the slope of the right triangle formed

thus, mathematically by using Pythagoras’ theorem;

The square of the hypotenuse equals the sum of the squares of the two other sides

Let us call the length of the water slide y

y^2 = 8^2 + 15^2

y^2 = 64 + 225

y^2 = 289

y = √289

y = 17 meters
