1- I know that 3 x 3 is 9 hours which will leads to these equations

3 x 3 = 9

5 x 3 = 15

2- Find out how long it takes for one lawn

5/3 = 1.6666...

1.6666.... x 9 =15

I hope Im correct!

Answer 2

Answer:

A healthy human heart beats about 1,533,000 times in a year. A sparrow's heart beats about

241,776,000 times in a year.

About how many times faster does the sparrow's heart beat compared to the human heart?

Estimate using a single digit times a power of 10.

2x108

or about 100 times faster

2x10

=1 x 102

0 2x10°

2x106

= 1 x 103

or about 1,000 times faster

2x108

2x105

=1 103

or about 1,000 times faster

2x109

2x105

=1 104

or about 10,000 times faster

Answers

Answer:

About 100 times faster

=1 x 10²

Step-by-step explanation:

Estimate using a single digit times a power of 10.

We approximate to the nearest whole number

A healthy human heart beats about 1,533,000 times in a year.

= 1.533 × 10⁶

As a single digit = 2.0 × 10⁶

A sparrow's heart beats about

241,776,000 times in a year.

= 2.41776 × 10⁸

As a single digit = 2 × 10⁸

About how many times faster does the sparrow's heart beat compared to the human heart?

We find the difference in their powers of 10

= ( 10^8 - 6)

= 10²

This means the sparrows heart beats at about

1 × 10² or a 100 times faster


The ratio of boys to girls in a group is 2:1. If there are 26 more boys than girls,
work out how many boys there are?


Answers

Answer:

26 girls are there

Step-by-step explanation:

2+1= 3- this is the number of parts the kids are divided into

2 - 1 = 1, in one part there are 26 extra boys

26/1=26- there are 26 boys and girls in one part

since there are an extra 26 boys, the boys have an extra part

boys-2 parts   girls-1 part

since 1 part has 26 kids , and the boys have 2 parts u need to multiply, 2*26=52, 52 boys in the class

since the girls have 1 part and here are 26 kids in one part the # of girls in the class are 26

During the worst periods of hyperinflation in a certain country. The price of food increased at a rate of 15% per month. State wether this is Linear or exponential

Answers

Answer:

exponential

Step-by-step explanation:

Since it is increasing per month at a percentage rate then this is an exponential increase. That is because each time the increase occurs it is adding the percentage on top of the previous month's increase which becomes compounded as the months go on. For example, the price of bread is $10, at the end of the first month the price increases by 15% (1.15 in decimal form since it is increasing)

10 * 1.15 = $11.5

Now it costs $11.50. This is a change of $1.50. The next month it increases by another 15%

11.50 * 1.15 = $13.22

Now it costs $13.22 which is an increase of $1.72. The increase in dollar amount will keep rising every time which makes it an exponential rise.

Francis Watson's gross pay is $61,100. He takes a married exemption of $3,000. His state income tax rate is 3.5 percent. How much will be deducted from his weekly paycheck for state taxes?

Answers

Answer:

$39.10

Step-by-step explanation:

in this problem we are  expect to solve for the taxable income and return the tax deductible

given data

gross pay is $61,100

married exemption of $3,000.

the taxable gross pay is

$61,100- $3,000.

=$58100

the tax deductible is 3.5% of pay

=3.5/100*58100

=0.035*58100

=2033.5

since the $2033.5 is the annual tax, in a year we have 52 weeks

therefore

=2033.5/52

= $39.10

8

4

So we multiply 7 by 4, and get 28.

Then we multiply 3 by 8, and get 24.

Next we give both terms new denominators -- 8 × 4 = 32.

So now our fractions look like this:

28

32

Since our denominators match, we can subtract the numerators.

28 − 24 = 4

Use function notation to write G in terms of the parent function F.? F(x)=x^3 and g(x)=-(x+1)^3

Answers

Answer:hey

Step-by-step explanation:

G in terms of the parent function F is given as  F(x) = -g(x-1).

What is a parent function?

A parent function is the simplest function of the family of functions that preserves the definition of entire family.

Now the given functions are,

F(x) = x^3

g(x) = -(x+1)^3

We can see that g(x) is just an opposite of translation of 1 units to the right of F(x), to write g(x) in terms of F(x)

Then we can write,

g(x-1) = -(x-1+1)^3

or, g(x-1) = -x^3

or, g(x-1) = -F(x)

or, F(x) = -g(x-1)

Hence,G in terms of the parent function F is given as  F(x) = -g(x-1).
