Answer:

see explanation

Step-by-step explanation:

the area (A) of a rectangle is calculated as

A = lw ( l is the length and w the width )

using the property [tex]\sqrt{a}[/tex] × [tex]\sqrt{a}[/tex] = a , then

A = 2[tex]\sqrt{7}[/tex] × 10[tex]\sqrt{7}[/tex]

  = 2 × 10 × [tex]\sqrt{7}[/tex] × [tex]\sqrt{7}[/tex]

  = 20 × 7

  = 140 ft²

----------------------------------------

the perimeter (P) is calculated as

P = 2(l + w)

  = 2(2[tex]\sqrt{7}[/tex] + 10[tex]\sqrt{7}[/tex] )

 = 2(12[tex]\sqrt{7}[/tex] )

 = 24[tex]\sqrt{7}[/tex] ft

we get the value of x as 2.4 units when QR is 18 units.

We are given a segment PR.

We are also given that Q is the mid point of the segment.

So, we get that

PQ = QR

Now, we have that

QR = 18 units

PR = 5 x + 6

We have to sind the value of x.

Substituting the values of PR and QR in the equation, we get that:

5 x + 6 = 18

5 x = 18 - 6

5 x = 12

x = 12 / 5

x = 2.4 units

Therefore, we get the value of x as 2.4 units when QR is 18 units.

The fluid force against the window is equal to 931.5 lb.

Given the following data:

Generally speaking, the fluid force that is exerted on the fish tank by the seawater is due to the liquid pressure acting over the given area. Also, the fluid force that is exerted on the fish tank is directly proportional to the depth of seawater.

The depth of seawater is given by:

Depth = 28.5 - 1.5

Depth = 27 inches.

Next, we would convert the unit of the depth of seawater and width of viewing portion in inches to feet:

1 inch = 12 feet

Depth = 27 inches to feet = 27/12 = 2.25 feet.

Width = 69/12 = 5.75 feet.

Now, we can calculate the fluid force against the window by using this formula:

Fluid force = (density × depth × width)/2

Fluid force = (64 × 2.25² × 5.75)/2

Fluid force = 1863/2

Fluid force = 931.5 lb.

Using proportions, it is found that she travels 60 miles from her house to the VAB on days her colleague drives.

A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct(when both increase or both decrease) or inverse proportional(when one increases and the other decreases, or vice versa), can be built to find the desired measures in the problem, or equations to find these measures.

The first step is finding the fraction corresponding to the 7 miles, hence considering that the total is of 100% = 1 and the fractions given above, we have that:

1 - 5/6 - 1/20 = 1 - 0.8333 - 0.05 = 0.1167.

The 7 miles represent 0.1167 of the trip, hence:

0.1167x = 7

x = 7/0.1167

x = 60.

Definition of perpendicular lines

Step-by-step explanation:

Shift 2 units left:  y = [tex](x+2)^{2}[/tex]

shift up 9 units:  y =  [tex](x+2)^{2}[/tex]  + 9

reflect in the x-axis:  y = -  [tex](x+2)^{2}[/tex] - 9

y =[tex]x^{2}[/tex]

Shift 2 units left:  y = [tex](x+2)^{2}[/tex]

Then, shift up 9 units:  y =  [tex](x+2)^{2}[/tex]  + 9

Then, reflect in the x-axis:  y = -  [tex](x+2)^{2}[/tex] - 9

Each reference coordinate line is referred to as an axis of the system, or simply an axis (plural axes),  and its origin is at the ordered pair intersection (0, 0). The positions of the perpendicular projections of the point onto the two axes, represented as signed distances from the origin, can likewise be used to establish the coordinates.

Items purchased:

x packs of pencils,

twice as many packs of erasers, total number of eraser packs = 2x

three times the number of tape rolls, number of tape rolls = 3x

total expenditure = x m + 2xn + 3xp = x(m + 2n + 3p)

We now have two possibilities:

1- All three goods are the same price:

cost of one pencil pack = cost of one eraser pack = cost of one roll of tape = m

Step-by-step explanation:

Given observations of two nests, one at 400 m, and the other at 300 m in a direction 135° from the first, you want to know the distance between the nests.

The law of cosines can be used to find the third side of a triangle, given two sides and the angle between them. It tells us ...

  c² = a² +b² -2ab·cos(C)

In this scenario, we have a=400, b=300, and C=135°. The distance c is then ...

  c² = 400² +300² -2·400·300·cos(135°) ≈ 419,705.63

  c ≈ √419,705.63 ≈ 647.8

The two nests are about 648 meters apart.

Using a system of equations, it is found that the maximum number of people that could be helped with one plane of supplies is: 40,000.

A system of equations is when multiple variables are related, and equations are built to find the values of each variable, according to the relations given in the problem.

For this problem, the variables are given as follows, considering the situation described:

Each food kit helped 8 people and each medicine kit helped 6 people, hence the total number of people helped is given by:

T = 8x + 6y.

This is because we consider that people were helped by only one of them, never both.

Each plane could carry no more than 80,000 pounds. Each food kit weighed 20 pounds and each medicine kit weighed 10 pounds, hence:

20x + 10y = 80000

2x + y = 8000

y = 8000 - 2x.

The maximum volume is of 6000 cubic feet, hence:

x + y = 6000.

y = 6000 - x.

Equaling both equations:

8000 - 2x = 6000 - x

x = 2000.

y = 6000 - x = 4000.

Then the maximum number of people helped is:

T = 8x + 6y = 8 x 2000 + 6 x 4000 = 40,000.
