A pile of pebbles has a weight of 95 kg.
Some of the pebbles put into a small bag.
The rest of the pebbles is put into a large bag.
The pebbles in the large bag weighs 45 kg more than the pebbles in the small
What is the weight of the pebbles in the large bag?​

Answers

Answer 1

Answer:

70kg

Step-by-step explanation:

s = small bag

b = big bag

Equations

s + b = 95

s + 45 = b

plug in

s + s + 45 = 95

2s + 45 = 95

2s = 50

s = 25

plug in to find big bag

25 + 45 = b

70 = b

Answer 2

Answer:

The weight of the pebbles in the large bag is 70kg.

Step-by-step explanation:

This looks like a substitution algebra problem. To do this, I’m going to mark the large bag with (L) and the small bag with the variable, (s). I will make first 2 equations to show the value. The first equation would be L=45+s. The second equation would be 95=L+s. Since L is literally 45+s, add this into the 2nd equation. This would be 95=45+s+s. You should have 95= 45+2s and you would subtract 45 from both sides then. Finally, divide 2s by 2 to get what the small bag weighs, (which is 25kg). To find the large bag’s weight, use the first equation to find the answer. L= 45+s or 25. The answer would bring us to 70 kg.

ABC have sides: 5, 7 and 10

5^2 + 7^2 = 25+47 = 72 < 10^2

so triangle ABC is obtuse

JKL has sides: 12, 35 and 37

12^2 + 35^2 = 144 + 1225 = 1369 = 37^2

so triangle JKL is right-angled

PQR has sides 12, 10 and 16

12^2 + 10^2 = 144 + 100 = 244 > 16^2

so triangle PQR is acute

Step-by-step explanation:

missing the Q: it asks 2 classify the triangles.

what is the experimental probability of rolling a 3 or 4?

Answers

If it's 3 or 4 the probability is:

2/6 or 1/3

We call the outcomes in an event its "favorable outcomes". If a die is rolled once, determine the probability of rolling a 4: Rolling a 4 is an event with 1 favorable outcome (a roll of 4) and the total number of possible outcomes is 6 (a roll of 1, 2, 3, 4, 5, or 6). Thus, the probability of rolling a 4 is .

HELP ME PLEASE! how do you write 610 as a scientific notation ??

Answers

Welcome to 610 in scientific notation, our post about writing the number six hundred and ten in scientific notation.

If you have been looking for 610 in exponential form, 610 as a power of 10, or what is 610 in scientific notation, then you are right here, too.

In this post you can find everything about the scientific notation of 610, including the normalized form and the number written in e-notation.

Read on to learn everything about the scientific notation of six hundred and ten.

To answer the question what is 610 in scientific notation let’s recall how to convert 610 to scientific notation as detailed on our home page.

When you split the number 610 into a coefficient and a power of 10 you do get 610 in exponential form, but there is an indefinite number of possibilities.

As you probably want 610 in normalized scientific notation, the coefficient or significand of 610 in scientific notation must be in the interval [1,10[.

As there are many ways to express 610 in scientific notation, in this post we mean 610 in normalized scientific notation, unless stated otherwise. Therefore:

610 in scientific notation = 6.1 × 102.

This can also be expressed as 6.1 × 10^2, using the caret symbol, or as 6.1e+2, which is called 610 in e-notation, further discussed in the section ahead.
Regarding our converter:

Our tool changes any decimal number including 610 to standard index form. If your press the swap button, then 610 is changed back to decimal form.

Our tool displays converted numbers in a special form of scientific notation, which means that the superscripted part of × 102 is denoted by ^2.

Q7. Average of 60 numbers are 55. When 10 more numbers are included, the average of
70 numbers become 75. Find the
average of 10 numbers.​

Answers

Answer:

The average of the 10 numbers is 195

Step-by-step explanation:

The average of a set of numbers is the sum of the numbers dividing by their number

Average = The sum ÷ The number

∵ The average of 60 numbers is 55

∴ The average = 55

∴ The number = 60

→ Substitute them in the rule above to find the sum of the numbers

∵ 55 = The sum ÷ 60

→ Multiply each side by 60

∴ 3300 = The sum

∴ The sum of the 60 numbers = 3300

∵ 10 more numbers are included

∵ The average of  70 numbers become 75

∴ The average = 75

∴ The number = 70

→ Substitute them in the rule above to find the sum of the numbers

∵ 75 = The sum ÷ 70

→ Multiply each side by 70

∴ 5250 = The sum

∴ The sum of the 70 numbers = 5250

∵ The sum of the 10 numbers that added is the difference between

   the sums of the 60 and 70 numbers

∵ The difference between the sums = 5250 - 3300

∴ The difference between the sums = 1950

→ To find the average of them divide their sum by 10

∵ The average of the 10 numbers = 1950 ÷ 10

∴  The average of the 10 numbers = 195

Find the constant of variation for the relation and use it to write an equation for the statement. Then solve the equation.

If y varies as directly as the square of x, and y = 75/8 when x = 5, find y when x= 2​

Answers

Answer:y=15/4

Step-by-step explanation:

start with general form y = kx. substitute in the pair of values you know for x and y.

75/8 = k(5) multiply both sides by 1/5 to solve for k, getting

15/8 = k

So your equation is y = (15/8)x substitute 2 for x to find your new y.

y = (15/8)2

y = 15/4

To find the perimeter, we add all of these together.
