At a certain electronics company, the daily output Q is related to the number of people A on the assembly line by Q=600+√(A+41).

Determine how many people are needed on the assembly line if the daily output is to be 621.

Answer:

A=400\ people

Step-by-step explanation:

we have

Q=600+\sqrt{A+41}

where

Q -----> is the daily output

A -----> is the number of people

For Q=621

Find the value of A

substitute and solve for A

621=600+\sqrt{A+41}

Subtract 600 both sides

621-600=\sqrt{A+41}

21=\sqrt{A+41}

squared both sides

21^{2} ={A+41}

441={A+41}

Subtract 41 both sides

441-41=A

Rewrite

A=400\ people

Answer:

-2(y+4)-2y >8

-2y-8-2y>8

-4y-8>8

-4y<8+8          

When you move a number on the other side it changes the side then > will become <

-4y<16

-4y/-4<16/-4

y<-4

in the figure below trianglePQM and triangleQRP are right triangles. the measure of lineQM is 6 and the measure of lineQP is 8.
Kipish [7]

Answer:

Option 4 is correct. The length of PR is 6.4 units.

Step-by-step explanation:

From the given figure it is noticed that the triangle PQR and triangle MQR.

Let the length of PR be x.

Pythagoras formula

hypotenuse^2=base^2+perpendicular^2

Use pythagoras formula for triangle PQM.

PM^2=QM^2+PQ^2

PM^2=(6)^2+(8)^2

PM^2=36+64

PM^2=100

PM=10

The value of PM is 10. The length of PR is x, so the length of MR is (10-x).

Use pythagoras formula for triangle PQR.

PQ^2=QR^2+PR^2

(8)^2=QR^2+x^2

64-x^2=QR^2                   .....(1)

Use pythagoras formula for triangle MQR.

MQ^2=QR^2+MR^2

(6)^2=QR^2+(10-x)^2

36=QR^2+x^2-20x+100

36-x^2+20x-100=QR^2        .... (2)

From equation (1) and (2) we get

36-x^2+20x-100=64-x^2

20x-64=64

20x=128

x=6.4

Therefore length of PR is 6.4 units and option 4 is correct.

Describe the two-dimensional cross section that would be created by slicing the cylinder-shaped cheese block as shown.
masha68 [24]

Answer: A RECTANGLE ( It has four sides, its opposite sides are congruent and all its angles measure 90 degrees)

Step-by-step explanation:

For this exercise it is important to remember the definition of a "Cross section".

In Geometry a "Cross section" is defined as that shape obtained when a three-dimensional figure is sliced by a plane.

In this case, according to the information given in the exercise, the cheese block has the shape of a cylinder. This is the three-dimensional figure.

Observe in the picture attached in the exercise that the  cylinder-shaped cheese block is cut through perpendicular to its base.

By definition, when this perpendicular cut happens, the shape obtained is  a Quadrilateral which has four  equal  angles that measure 90 degrees and whosepposite sides are parallel have equal length.

Therefore, you can conclude that the two-dimensional cross section that would be created by slicing the cylinder-shaped cheese block perpendicular to its base,is: A RECTANGLE.

how to find the volume of each sphere, both in terms of \pi and the nearest tenths for r=3 use 3.14 for \p.
icang [17]
Volume formula of a sphere:
\frac{4}{3}\pir³

given:
r = 3 

V = \frac{4}{3}\pi(3)³
V = \frac{4}{3} × 27\pi
V = 36\pi units³ (in terms of \pi)
V = 113.097 units³ ≈ 113.1 units³
