Solve for b. 13/b = 8/1 A. b=1.25 B. b=1.26 C. b=16.25 D. b=1.625

Sati [7]

Answer: $b=13/8$

Cross multiply

$(13)*(1)=8*b\\13=8b$

Flip the equation

$8b=13$

Divide both sides by 8

$8b/8=13/8\\b=13/8$

Total piston displacement is given by the following formula: TT P.D.ED?LN 4 Where P.D. = piston displacement, in cubic inches D

Ede4ka [16]

Answer: ≈ 1696460.03

Step-by-step explanation:

Formula:

$P.D.=(\frac{\pi }{4})D^2LN$ ⇒ $\left(\frac{\pi }{4}\right)400^2\cdot 4.5\cdot 6$

Steps:

1. calculate pi and inset into equation

$=0.785398(400^2)(4.5)(6)$

2. calculate exponents

$=(0.785398)(160000)(4.5)(6)$

3 . multiply the rest

$=(125663.706144)(4.5)(6)$

$=(565486.677646)(6)$

4. divide by 2 to get the diameter

$=\frac{3392920.065877}{2}$

5. round to the nearest hundredth (2 decimal points)

$= 1696460.032938$ ≈ 1696460.03

Hope this helped!

The function y=60+25sin(pi/6)t, where t is in months and t=0 corresponds to April 15, models the average high temperature in deg

BartSMP [9]

Answer:

The maximum temperature will be of 85 degrees, on July 15.

Step-by-step explanation:

Sine function:

The sine function oscilates between -1 and 1, and it's maximum value is:

$\sin{(\frac{\pi}{2})} = 1$

y=60+25sin(pi/6)t

The maximum value will occur when $\sin{(\frac{\pi t}{6}}) = 1$ , and it will be of 60 + 25 = 85 degrees.

When will it occur?

First we find the value of t for which the value inside the function sine is $\frac{\pi}{2}$ . So

$\frac{\pi t}{6} = \frac{\pi}{2}$

$\frac{t}{6} = \frac{1}{2}$

$2t = 6$

$t = \frac{6}{2} = 3$

That is the number of months after April 15, which is 3 months. So July 15.
