Answer:
Perimeter of rectangle is 16 cm and the area of square is 1 cm^2
Step-by-step explanation:
Here, we want to get the perimeter of rectangle and area of square
From the question, the rectangle has 2 rows of 6 squares each; So we have the length as 2 cm and the width as 6 * 1 cm = 6 cm
So the rectangle is 6 cm by 2 cm
The perimeter of a rectangle is 2(l + b)
so, we have 2(6 + 2) = 2(8) = 16 cm
The area of the square is simply the side length raised to the power of 2
we have this as 1^2 = 1 cm^2

A computer network manager wants to test the reliability of some new and expensive fiber optic Ethemet cables that the computer department just received . The computer department received 10 boxes containing 50 cables each The manager does not have the time to test every cable in each box The manager will choose one box at random and test 10 cables chosen randomly within that box What is the population
Answer: 500 cables
Step-by-step explanation:
The population refers to the individuals or the items which are of interest fltonthe researcher during an experiment.
Since the computer department received 10 boxes containing 50 cables each, then the population will be gotten as:
= 10 × 50
= 500 cables

Answer:
-6 and -1
Step-by-step explanation:
The excluded values are the values of x that satisfy [tex]2x^{2} + 14x + 12 = 0[/tex]
Let us solve the equation [tex]2x^{2} + 14x + 12 = 0[/tex]
It's a quadratic equation
Thus, let us calculate the discriminant Δ
Δ [tex]= 14^{2} - 4 .2.12 = 100[/tex]
the discriminant is greater than 0, so the equation has two solutions
[tex]x = \frac{-14 - 10}{4} = \frac{-24}{4} = -6[/tex] or [tex]x = \frac{-14+10}{4} = \frac{-4}{4} = -1[/tex]
the excluded values are -6 and -1

Is the point (15,29)on the line y = 2x-3?
Answer:No
Step-by-step explanation: It is on 3x-3
The point (15, 29) does not satisfy the line y = 2x - 3, and the point (15, 29) is not lying on the line.
What is a linear equation?It is defined as the relation between two variables if we plot the graph of the linear equation we will get a straight line.
If in the linear equation one variable is present then the equation is known as the linear equation in one variable.
We have a line:
y = 2x - 3
If the point (15, 29) is on the lie then it must satisfy the line.
Therefore putting this point in the equation of the line.
Put x = 15, and y = 29, we get:
29 = 2×15 - 3
= 30 - 3
29 ≠ 27
29 cannot be equal to 27 it means the point (15, 29) does not satisfy the line and the point is not lying on the line.
Thus, the point (15, 29) does not satisfy the line y = 2x - 3, and the point (15, 29) is not lying on the line.

Find the area of the shaded region in the figure above using two different ways. Do you get the same
answer both ways? Investigate what's going on here.
Answer:
Below
Step-by-step explanation:
First way:
Find the area of the big triangle and subtract the area of the rectangle.
Area of shaded part = 1/2 * 25 * 34 - 10*24 = 185 m^2
Second way:
Add the area of the 3 shaded triangles:
= 1/2 * 15 * 24 + 1/2 * 5 * 10 + 1/2 * 5 * 10
= 180 + 25 + 25 = 230 m^2
The areas are different. The reason must be that given lengths are not possible for this diagram.
Check The length of the hypotenuse of the large triangle by 2 different methods:
The hypotenuse = √(25^2 + 17^2)
= 30.23.
Now let's work out the hypotenuse of the shaded triangles:
Top one = √(15^2 ^ 12^2) = 19.21
Bottom one = √((5^2 + 10^2) = 11.18
Adding these we get 30.39 which is different than previously calculated but it should be the same.
So what we have here is impossible geometry. This accounts for the different areas.

Answer:
Area = 1053.59²
Step-by-step explanation:
Area = Area of cylinder + Area of rectangular prism
Area of cylinder = 2 π r h + 2 π r² [ r = 4, h = 8]
= 2 π r ( h + r)
= 2 π x 4 ( 8 + 4)
= 301.59 ft²
Area of rectangular prism = 2 ( 12 x 8 + 8 x 14 + 14 x 12) = 752 ft²
Area = 301. 59 + 752 = 1053.59²

34.2 ; 105.8 ; 12.0
Step-by-step explanation:
[tex]\frac{a}{sinA}[/tex] = [tex]\frac{b}{sinB}[/tex] = [tex]\frac{c}{sinC}[/tex]
c² = a² + b² - 2abcosC
~~~~~~~~~~~~
sinB = [tex]\frac{bsinA}{a}[/tex]
sinB = 7sin40° ÷ 8 ≈ 0.562439
m∠B ≈ 34.2°
m∠C = 180° - ( 40° + 34.2° ) = 105.8°
c² = 8² + 7² - 2(8)(7)cos106° ≈ 143.87
c ≈ 12.0 units
The perimeter of a rectangle is twice the sum of its length and its width. The perimeter is 22 meters and its length is 2 meters more than twice its width. 0
Answer:
Length = 6.5 meters
Width = 4.5 meters
Step-by-step explanation:
Given,
Perimeter of a rectangle is twice the sum of it's length and width.
Length is 2 meters more than twice its width, let the length be x meters so the width becomes (x-2) meters
perimeter of the rectangle,
2{x+(x-2)} meters which is 22 meters (given)
so,
2{x+(x-2)}=22
or, 2(x+x-2)=22
or, 2(2x-2)=22
or, 2x-2=11
or, 2x=13
or, x=6.5
so the length is 6.5 meters and the width is 6.5-2 = 4.5 meters.

Use trigonometry to solve the triangle shown. Round all side lengths to one decimal place and
all angle measures to the nearest whole degree.
Answer/Step-by-step explanation:
Recall: SOH CAH TOA
✔️Find <A:
Reference angle (θ) = A
Opposite side = 14 cm
Hypotenuse = 20 cm
Apply SOH:
Sin θ = Opp/Hyp
Substitute
Sin A = 14/20
A = [tex] sin^{-1}(\frac{14}{20}) [/tex]
m<A = 44° (nearest whole number)
✔️Find <C:
Reference angle (θ) = C
Adjacent side = 14 cm
Hypotenuse = 20 cm
Apply CAH:
Cos θ = Adj/Hyp
Substitute
Cos C = 14/20
C = [tex] cos^{-1}(\frac{14}{20}) [/tex]
m<C = 46° (nearest whole number)
✔️Find AB:
Reference angle (θ) = C = 46°
Opposite side = AB
Hypotenuse = 20 cm
Apply SOH:
Sin θ = Opp/Hyp
Sin 46° = AB/20
20*Sin 46° = AB
AB = 14.4 cm (one decimal place)
the city central library has 72,864 books and 72 bookcases how many books are there in each bookcase
Answer:
1,012
Step-by-step explanation:
72,864 / 72 = 1,012
Answer:
1012 books per bookcase
Step-by-step explanation:
Assuming each bookcase has the same number of books, this is a division task.
Your answer will be given by number of books÷number of bookcases.
In this case, that becomes 72864÷72.
This can be solved to 1012.

Answer:
B) 5 units
Step-by-step explanation:
The distance between these points (0, 2) and (5, 2) will be 5 units. Then the correct option is B.
What is the distance between two points?It is the measure of distance between the two points and is known as length. The length is measured in meters generally.
Let one point be (x, y) and another point be (h, k).
Then the distance between the points will be
D² = (x - h)² + (y - k)²
The two pints are given below.
(0, 2) and (5, 2)
Then the distance between these points (0, 2) and (5, 2) will be given as,
D² = (5 - 0)² + (2 - 2)²
D² = 5²
D = 5 units
The distance between these points (0, 2) and (5, 2) will be 5 units. Then the correct option is B.
