Charles has six times as many action figures as ben together the action figures total more than 75 how many does each have

seropon [69]

Answer:

We have been given that Charles has six times as many action figures as Ben

Let Ben has x action figures

So according to question Charles will have 6x.

together the action figures total more than 75

$x+6x>75$

$7x>75$

$x>\frac{75}{7}$

So Ben will have more than $\frac{75}{7}$ action pictures.

And $6x>6\frac{75}{7}$

$6x>\frac{450}{7}$

Charles will have more than $\frac{450}{7}$ .

Find the area of the shaded regions. Give your answer as a completely simplified exact value in terms of π (no approximations).

olga_2 [115]

Answer:

$7\pi cm^2$

Step-by-step explanation:

The area of a circle is given by $A=\pi r^2$

For circle B, the radius is 3 cm, it has an area of $\pi *3^2=9\pi cm^2$

Circle D also has a radius of 1 cm. Its area is $\pi *1^2=\pi cm^2$

Circle P also has a radius of 1 cm and area $\pi*1^2=\pi cm^2$

The area of the shaded region is then $9\pi -\pi-\pi=7\pi cm^2$

Solve the system using linear combination.

Angelina_Jolie [31]

Answer:

Delta does not have a relative extreme in the equation, so it is variable y It can not be true

Step-by-step explanation:

$s = 5x + 3y$

There is an answer

The rest of the equation that has no substituted delta is not true, so the prime variables have relative extremes.

Estimate the isoelectric point of a ser–his dipeptide. explain why this value is only an estimate.

uranmaximum [27]

A dipeptide bond connects two amino acids. Ser stands for Serine while His stands for Histidine. Isoelectric point is when all charges of the two amino acids cancel out. This can be estimated by finding the average of the isoelectric points (pI) of the two amino acids.

Serine: pI = 5.68
Histidine: pI = 7.59

Average pI = (5.68 + 7.59)/2 = 6.635

This is only a rough estimate because an arithmetic average will not coincide with the biochemistry of the amino acids. The true value of the isolectric point is determined through experimentation. However, it would be more ore less around 6.635.
