Explanation on how to place the decimal places I found on a good website:

Decimals are multiplied as if they were whole numbers, and then the decimal point is placed in the product.

To find out where the decimal point should be placed, count the number of decimal places after the decimal point in each factor.

 

Multiply 0.7 by 0.352

   0.7      1 decimal place

0.352      3 decimal places

              A total of 4 decimal places

Once you have found the sum of the decimal places in each factor, you know how many decimal places the product will need after its decimal point. Starting at the far right of the number, move the decimal point toward the left that number of decimal places.

   

0.2464 (4 decimal places after the decimal point)

Dividing decimals

1.  Move the decimal point in the divisor to the right to make the divisor a whole number.  

2.  Move the decimal point in the dividend the same number of places to the right.  

3.  Place the decimal point in the quotient directly over the decimal point in the dividend for the final quotient.

4.  Divide as if working with whole numbers

Which tree is growing faster

Answers

Answer:

tree 1 is growing faster

Using the slope of a linear function, it is found that Tree 1 is growing faster.

What is a linear function?

A linear function is modeled by:

[tex]y = mx + b[/tex]

In which:

m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1. It can be given by the change in the input divided by the change in the output.b is the y-intercept, which is the value of y when x = 0.

In this problem:

Tree 1 is growing 1.5 inches every week.For tree 2, when the week increasing by 1, the height also increases by 1, hence the slope is 1, which means that it is increasing 1 inch per week.Thus, tree 1 is growing faster.

if the cost price of 10 tables is equal to the selling price of 16 tables , find out the gain or loss percentage​

Answers

Hi,

To solve this problem, Let us take the LCM of 10 and 16 which will come 80.

Now suppose the cost price of 10 tables =₹n CP of 80 tables will be ₹ 8n

According to the question, CP of 10 tables is equal to the SP of 16 tables, then

the SP of 16 tables will also be ₹ n.

So, SP of 80 tables will be ₹ 5n

So, Loss = CP-SP

→ 8n - 5n = ₹ 3n

Loss%= (3n×100)/8n

Loss%= 37.5%.

Hence the correct answer will be a loss of 37.5%.

Answer:

the length of each shape will alternate between even numbers and is numbers.

Step-by-step explanation:

just think !

there are 3 cubes in the basic shape.

now, with every step he adds 1 more cube to the length, and one more cube to the height. that means 2 more cubes.

so, it goes 3, 5, 7, 9, ... cubes

therefore, the first answer is wrong. the shape in every step will always have an uneven (odd) number of boxes. remember, adding an even number to an uneven number will always result in an uneven number. only uneven and uneven or even and even can have even results.

but the length itself - he only adds there one box at a time, will go

2, 3, 4, 5, 6, ...

so, it will alternate between even and uneven numbers.

Group discounted lift tickets were $14 for those paying with cash and $15 for those
paying with a credit card. The total paid by the group was $177.00. Three times as many
people paid with a credit card as those who paid with cash. How many people paid with
cash?
PLEASE ANSWER WITH AN EXPLANATION

Answers

Answer:

3 people

Step-by-step explanation:

Let "x" represent the number of people who payed with cash

Let "y" represent the number of people who payed with credit card

14x +15y = 177 ---------1

3x =y--------- 2

solving simultaneously,

put eqn 2 into eqn 1

14x + 15 (3x) = 177

14x + 45x = 177

59x = 177

x=3

From eqn 2 , y = 3 x

y = 3 (3)

y=9

therefore the number of people who paid with cash were 3.

Gavin and Jim win some money and share it in the ratio 5:2. Gavin gets £39 more than Jim. How much did they get altogether?

Answers

Answer:

They got $91 in total

Step-by-step explanation:

I did some trial and error and when I reached 65 dollars for Gavin I realized that Jim would be $29. So 65 - 29 = $39. Btw substitute $ for £

Answer: £91

Step-by-step explanation:

Let x be the amount of money Jim gets

Let x + 39 be the amount of money Gavin gets

Given information

Ratio = 5 : 2 (Gavin to Jim)

Jim = x

Gavin = x + 39

Set up proportion

5 / 2 = (x + 39) / x

Cross multiply to reduce fraction form

5x = 2 (x + 39)

Expand parentheses and apply the distributive property

5x = 2 · x + 2 · 39

5x = 2x + 78

Subtract 2x on both sides

5x - 2x = 2x + 78 - 2x

3x = 78

Divide 3 on both sides

3x / 3 = 78 / 3

x = 26

Find the amount of money they get altogether

Gavin + Jim

=x + 39 + x

=(26) + 39 + (26)

=65 + 26

The center circle on a soccer field has a radius of 9 yards. What is the area of the center circle? Use 3.14 for pie

Answers

Answer:

[tex]\boxed {\boxed {\sf 254.34 \ yd^2}}[/tex]

Step-by-step explanation:

The area of a shape is the space occupied by the surface of an object. The area of a circle can be calculated using the following formula.

[tex]a= \pi r^2[/tex]

The radius (r) of the center circle on the soccer field is 9 yards. We are asked to use 3.14 for pi.

r= 9 yd π= 3.14

Substitute these values into the formula.

[tex]a= (3.14)(9 \ yd)^2[/tex]

Solve the exponent.

(9 yd)² = 9 yd * 9 yd = 81 yd²

[tex]a= (3.14)(81 \ yd^2)[/tex]

Multiply.

[tex]a= 254.34 \ yd^2[/tex]

The area of the center circle on the soccer field is 254.34 square yards.
