Well simply put we know that Celia's collection of cards is bigger because it tells us that it is 4/3 times bigger than franks. If you convert 4/3 to a percent you would see that is is over a hundred percent, so you know hers is bigger than his.

An account earns simple interest.

olasank [31]

Data:
P (Principal) = $1500
I (Simple Interest) = ?
t (time) = 5 years
r (percentage rate) = 4% = 0.04

Formula:
$I = P*r*t$

Solving (1) <span>Find the interest earned.</span>
$I = P*r*t$
$I = 1500*0.04*5$
$\boxed{\boxed{I = 300}}\end{array}}\qquad\quad\checkmark$

Solution (2) <span>Find the balance of the account.
</span>The future value, (Account), of a loan is given by the equation: A = P + I
$A = P + I$
$A = 1500 + 300$
$\boxed{\boxed{A = 1800}}\end{array}}\qquad\quad\checkmark$

A triangular plate with base 2 m and height 3 m is submerged vertically in water so that the tip is even with the surface. Expre

g100num [7]

Answer:

Hydrostatic Force = 35.28KN

Step-by-step explanation:

To solve this question, let's consider integrating the hydrostatic force from the top of the triangle to the bottom.

Formula for a thin horizontal slice of the triangle the force is;

δF=ρgxwδx

Where w is width of triangle; ρ is density of water and g is acceleration due to gravity

At depth x, the width of the triangle is w=2/3x.

Thus, F = (3,0)∫)ρgxwδx

=(2/3)ρg[(3,0)∫)x²δx]

= integrating, we have;

F = (2/3)ρg[(3³/3) - (0³/3)]

F = (2/5)ρg [27/3] = (2/5)(1000)(9.8)(9) = 35280 N = 35.28 KN
