Answer:

2304.8 ft^2

Step-by-step explanation:

The lateral area of one of the pyramid is 21.5 * 13.4 * 4/2 = 576.2

There are 4 of them, so we multiply that by 4 : 576.2 * 4 = 2304.8

Give that T = 37v/6v-5.4m a. Make V the subject of relation b. If T = 4.5 and M =7x10(7),calculate the value of v , leaving your

PilotLPTM [1.2K]

Answer:

$v = \frac{5.4mT}{6T - 37}$

$v = -1.701*10^8$

Step-by-step explanation:

Given

$T = \frac{37v}{6v-5.4m}$

Solving (a): Make v the subject

$T = \frac{37v}{6v-5.4m}$

Cross Multiply:

$(6v-5.4m)T = 37v$

Open bracket

$6vT - 5.4mT = 37v$

Collect Like terms

$6vT - 37v= 5.4mT$

Factorize:

$(6T - 37)v= 5.4mT$

Make v the subject

$v = \frac{5.4mT}{6T - 37}$

Solving (b):

$T = 4.5$

$m = 7 * 10^7$

So, the expression becomes:

$v = \frac{5.4mT}{6T - 37}$

$v = \frac{5.4*7*10^7*4.5}{6*4.5 - 37}$

$v = \frac{170.1*10^7}{27 - 37}$

$v = \frac{170.1*10^7}{-10}$

$v = -17.01*10^7$

$v = -1.701*10*10^7$

$v = -1.701*10^8$

Payton leaves to go on an 858585 minute bike ride at 3{:}27\text{ p.M.}3:27 p.M.3, colon, 27, start text, space, p, point, m, po

svp [43]

There are no 858585 minutes between 3:27 PM and 5:45 PM when Payton's family eats dinner, as this would mean that Payton goes on over 596 day bike ride, which is unrealistic.

The question would be realistic, if it was:

Payton leaves to go on an 85 minute bike ride at 3:27 PM.

Payton's family eats dinner at 5:45 PM. How much time will Payton have between finishing her bike ride and eating dinner?

Answer:

Payton has 53 minutes between finishing her bike ride and eating dinner

Step-by-step explanation:

- Payton rides for 85 minutes.

If she starts by 3:27 PM, she would finish by 4:52 PM.

- Dinner is by 5:45 PM.

We are required to find how much time is between 4:52 PM and 5:45 PM.

Subtract:

.........H...............M

.........05............45

.........04............52

.................................

.........00............53

Payton has 53 minutes
