4+2.50x=21.50

You know you need 4 dollars to enter so you have that then 2.50 is the cost for one ride and x is how many rides you can ride

To solve you need to solve for x by subtracting 4 on both sides then dividing both sides by 2.50

Answer:

7 rides

Equation 21.50 = 2.50x + 4

Step-by-step explanation:

21.50 - 4 = 17.50

17.50/2.50 = 7

21.50 = 2.50x + 4

x is the amount of rides

Each day, the human heart pumps about 7500 liters of blood. As a simple approximation, assume that the work done by the heart is
erik [133]

Answer with Step-by-step explanation:

We are given

Volume of blood=V=7500 L=7500\times 0.001=7.5 m^3

1 liter=0.001 m^3

Height of person=h=1.5 m

Density of blood,\rho=1050 kg/m^3

We have to find the work done and power of person's heart.

We know that

Work done,W=mgh=\rho Vgh

Where g=9.8 m/s^2

Using the formula

W=1050\times 7.5\times 9.8\times 1.5=1.16\times 10^5 J

Time,t=1 day=24\times 60\times 60=86400 s

Power, P=\frac{W}{t}

Using the formula

P=\frac{1.16\times 10^5}{86400}=1.34 Watt

Show a way to count from 668 to 900 using ones, tens, and hundreds
zmey [24]

Answer

668 + 232 ones = 900

or

668 + 23 tens + 2 ones = 900

or

668 + 2 hundreds + 32 ones = 900

or

668 + 2 hundreds + 3 tens + 2 ones.

<u>Explanations</u>

900 - 668 = 232. Meaning we can add 232 ones to 668 to get 900.

232-200 = 32 ⇒ Meaning, we can add 2 hundreds and 32 ones to 668 to get 900.

32-30 = 2. This means we can add 2 hundreds, 3 tens and 2 ones to 668 to get 900.

900 - 668 = 232
