So yes the board is wide enough. The are 10 decimeters in a meter.

What it is asking you to do in the example above is multiply 2.5/23.5 by 1.2 both top and bottom aka the numerator and denominator. This makes it easier to view and divide.

I didn't use this method I just looked at it but give it a try for your answer to B

Hattie had $6600 to invest and wants to earn 4% interest per year. She will put some of the money into an
34kurt

Answer:

The amount of money that should be invested at the rate of 12% is $900 and the amount of money that should be invested at the rate of 10% is $2,100

Step-by-step explanation:

Let

x ------> the amount of money that should be invested at the rate of 12%

3,000-x -----> the amount money that should be invested at the rate of 10%

we know that

The sum of the interest on each of the accounts must be equal to the total interest.

Solve for x

therefore

The amount of money that should be invested at the rate of 12% is $900 and the amount of money that should be invested at the rate of 10% is $2,100

Hope this helps you!!!! :D

Find the general solution of the following equation: y'(t) = 3y -5
Anton [14]

Answer:

The general solution of the equation is y = \frac{A}{3}e^{3t} + 5

Step-by-step explanation:

Since the differential equation is given as y'(t) = 3y -5

The differential equation is re-written as

dy/dt = 3y - 5

separating the variables, we have

dy/(3y - 5) = dt

dy/(3y - 5) = dt

integrating both sides, we have

∫dy/(3y - 5) = ∫dt

∫3dy/[3(3y - 5)] = ∫dt

(1/3)∫3dy/(3y - 5) = ∫dt

(1/3)㏑(3y - 5) = t + C

㏑(3y - 5) = 3t + 3C

taking exponents of both sides, we have

exp[㏑(3y - 5)] = exp(3t + 3C)

3y - 5 = e^{3t}e^{3C}        

3y - 5 = Ae^{3t}                A = e^{3C}

3y = Ae^{3t} + 5    

dividing through by 3, we have

y = \frac{A}{3}e^{3t} + 5

So, the general solution of the equation is y = \frac{A}{3}e^{3t} + 5

Eric is designing a logo for a company. The logo consists of two identical parallelograms joined at their longest sides. One of
Sati [7]

Answer:

A=3.125\ cm^2

Step-by-step explanation:

Given that,

The base of the parallelogram, b = 2.5 cm

Height of the parallelogram, h = 1.25 cm

We need to find the area of the logo. The formula for the area of the parallelogram is given by :

A=b\times h\\\\A=2.5\times 1.25\\A=3.125\ cm^2

So, the area of the logo is 3.125\ cm^2.
