Step-by-step explanation:

Step 1:

Let the number be 50 and to find 40% of 50 is given interms of expression as follows

To express the percentage the following strategy is used

Eg: 40% = $40/100$

∴ To express 40% of 50 is

$(40/100)*50$

Step 2:

On simplification the above expression we could get

$0.4*50$

= 20

<h3><u>3</u><u>6</u> is the answer.</h3>

Step-by-step explanation:

Put value of b as given and using BODMAS rule,

$6(2b - 4)$

$= > 6((2 \times 5)-4)$

$= > 6(10 - 4)$

$= > 6 \times 6$

$= > 36$

Henve, value of of the given expression is $36$

For the years from 2002 and projected to 2024, the national health care expenditures H, in billions of dollars, can be modeled b

dmitriy555 [2]

Answer:

2019.

Step-by-step explanation:

We have been given that for the years from 2002 and projected to 2024, the national health care expenditures H, in billions of dollars, can be modeled by $H = 1,500e^{0.053t}$ where t is the number of years past 2000.

To find the year in which national health care expenditures expected to reach $4.0 trillion (that is, $4,000 billion), we will substitute $H=4,000$ in our given formula and solve for t as:

$4,000= 1,500e^{0.053t}$

$\frac{4,000}{1,500}=\frac{ 1,500e^{0.053t}}{1,500}$

$\frac{8}{3}=e^{0.053t}$

$e^{0.053t}=\frac{8}{3}$

Take natural log of both sides:

$\text{ln}(e^{0.053t})=\text{ln}(\frac{8}{3})$

$0.053t\cdot \text{ln}(e)=\text{ln}(\frac{8}{3})$

$0.053t\cdot (1)=0.9808292530117262$

$\frac{0.053t}{0.053}=\frac{0.9808292530117262}{0.053}$

$t=18.506212320$

So in the 18.5 years after 2000 the expenditure will reach 4 trillion.

$2000+18.5=2018.5$

Therefore, in year 2019 national health care expenditures are expected to reach $4.0 trillion.

The area of a triangle is 45.5 cm2 and the base is 10 cm.

blondinia [14]

The area of a triangle is A=1/2b*h
You have the base (b) and you have the area (A)
So, if you plug in what you know, you get this:
45.5=1/2*10*h
Simplify it:
45.5=5h

Now solve for h
Divide by 5 to get h alone:
9.1=h

Your height is 9.1cm
Hope this helps :)
