One page of a petition can hold p signatures. You were able to get 4p+5 people to sign the petition. Your friend was able to get
leva [86]

Answer:

6p - 2

Step-by-step explanation:

The expression that needs to be made in this question refers to the total number of people that signed the petition. To calculate this we need to add the total number of signatures that both you and your friend were able to acquire. Once we do this we simply combine like terms in order to simplify the expression as much as possible.

4p + 5 + 2p - 3

4p + 2p + 5 - 3

6p - 2

Therefore, the total and simplified expression for the total number of signatures would be 6p - 2

The following set of coordinates represents which figure? (1, 1), (5, 3), (7, 7), (3, 5) (4 points)
slamgirl [31]
Check the slopes 
the first 2 points have slope (3-1) / (5-1) = 2/4  = 1/2
points 2 and 3 slope =  4/2 = 2
3 and 4:- slope = -2/-4 = 1/2
4 and 1:- slope =  4/2 = 2

so we have 2 pairs of opposite sides which are parallel

looks like a parallelogram or a rhombus 

if adjacent sides are equal its a rhombus

length betwee  pts 1 and 2  = sqrt(2^2 + 4^2) = sqrt20
 .. ...  ...   ..  ..   .. ...2 and 3 =  sqrt(4^2 + 2^2) = sqrt20

so it is a rhombus

If a cup of coffee has temperature 97°C in a room where the ambient air temperature is 25°C, then, according to Newton's Law o
FinnZ [79.3K]

Answer:

The  average temperature  is T_{a} = 81.95^oC

Step-by-step explanation:

From the question we are told that

    The temperature of the coffee after time t is   T(t) =  25 + 72 e^{[-\frac{t}{45} ]}

Now the average temperature during the first 22 minutes i.e fro 0 \to  22minutes is mathematically evaluated as

              T_{a} =  \frac{1}{22-0}  \int\limits^{22}_{0} {25 +72 e^{[-\frac{t}{45} ]}} \, dx

               T_{a} = \frac{1}{22} [25 t  +  72 [\frac{e^{[-\frac{t}{45} ]}}{-\frac{1}{45} } ] ] \left| 22} \atop {0}} \right.

             T_{a} = \frac{1}{22} [25 t  - 3240e^{[-\frac{t}{45} ]} ] \left | 45} \atop {{0}} \right.

              T_{a} = \frac{1}{22} [25 (22)  - 3240e^{[-\frac{22}{45} ]}   - (- 3240e^{0} )]

            T_{a} = \frac{1}{22} [550  - 1987.12  +  3240]

          T_{a} = 81.95^oC

Heather had six 2-liter bottles of blood. She poured the blood into glasses which each have a capacity of 3 deciliters. How many
Flauer [41]
The human body has about 5.5 liters of blood
3 deciliters is about 0.3 liters
so 5.5/0.3=18.33333
so she could fill 18 and 1/3 glasses before she died
wait
oooooh, she has a supply of blood other than her own, nvm, I should read better


1 decileter is 1/10 of a liter
so 3/10 of a liter per glass

6 of those 2 liter bottles
so total is 6*2=12 liters
so
3/10 times number of glasses=12
times both sides by 10/3
number of glasses=120/3
number of glasses=40
can fill 40 glasses with the blood she is supplied (not including her own)
