Number of households without computer in 2009
From the attachment, we have:
[tex]n=5170000[/tex] --- survey
[tex]p = 22.3\%[/tex] --- proportion without computer
So, the actual number is:
[tex]Number = p * n[/tex]
[tex]Number = 22.3\% * 5170000[/tex]
[tex]Number = 1152910[/tex]
[tex]Number \approx 1153000[/tex]
Hence: (B) is correct
Angles 1 and 2 are supplementary. Angle 2 is 1/5 the size of angle 1. What are the degree measurements of each angle?
Answer:
the stated ratio means that of the 180 degrees involving two supplementary angles, the smaller angle is one sixth of that whole. Thus the smaller angle measures 30 degrees & the larger measures 150 degrees.

In the given diagram, the value of x is 15
Pythagorean theoremThe Pythagorean theorem states that, in a right triangle, the square of the longest side (hypotenuse) equals sum of squares of the other two sides
From the question, we are to determine the value of x.
x is the radius of the circle
Recall: Radius is any line that runs from the center to any part of the circumference
Consider the right triangle formed, x is the hypotenuse
By the Pythagorean theorem,
x² = 9² + 12²
x² = 81 + 144
x² = 225
x = √225
x = 15
Hence, the value of x is 15.

In parallelogram HJKL if m<KLH=170 find m<LHJ
Answer:
bro what is even happening here
so confused but okay
Answer:
∠ LHJ = 10°
Step-by-step explanation:
Consecutive angles in a parallelogram sum to 180°
Then
∠ KLH + ∠ LHJ = 180°
170° + ∠ LHJ = 180° ( subtract 170° from both sides )
∠ LHJ = 10°
The number of bacterial cells, B, in a container after t hours is given by B=25x2t After how many hours will there be 400 bacterial cells in the container?
Answer:
8 hours
Step-by-step explanation:
We have that;
B = number of bacterial cells, B, in a container after t hours
t = time taken in hours
The function is;
B=25x2t
Where B = 400 bacterial cells
400 = 25x2t
t = 400/25x2
t = 8 hours
Select all the expressions that are equivalent to 3x−4+2x−6.
Answer:
5x-10
Step-by-step explanation:
3x-4+2x-6
group like terms
3x+2x -4--6
5x-10
The expressions that are equivalent to 3x - 4 + 2x - 6 are:
5x - 2 - 6
5x - 16
To determine which expressions are equivalent to 3x - 4 + 2x - 6, we can simplify the given expression:
3x - 4 + 2x - 6
Combining like terms, we have:
(3x + 2x) + (-4 - 6)
Simplifying further:
5x - 10
Now, we can compare this simplified expression to the provided options:
a) 3x + 2x - 10
b) 5x - 2 - 6
c) 5x - 16
d) 6x - 10
By comparing the simplified expression 5x - 10 to the options, we find that options b) (5x - 2 - 6) and c) (5x - 16) are equivalent expressions.

Which of the shapes below are quadrilaterals? Select all that apply.
A) rectangle
B) parallelogram
C) square
D) rhombus
Answer:
A, B, C, D
Step-by-step explanation:
Quadrilaterals are shapes that have a total of four sides. Rectangles, parallelograms, squares, and rhombuses all have a total of four sides. Therefore, they are quadrilaterals.
Rectangle, Parallelogram, Square and Rhombus are Quadrilaterals.
We know,
A quadrilateral is a polygon with four sides. It is a geometric shape that is characterized by having four straight sides and four vertices. The interior angles of a quadrilateral add up to 360 degrees.
As, Rectangle have four sides then it is a quadrilateral.
As, Parallelogram have four sides then it is a quadrilateral.
As, Square have four sides then it is a quadrilateral.
As, Rhombus have four sides then it is a quadrilateral.

The fountain is made up of two semicircles and one quarter circle. Find the perimeter and area of the fountain.
Answer:
628ft²
Step-by-step explanation:
From the diagram, we are given the following
diameter of the semicircles
2semi circles = 1 circle
Area of 2semicircles = πd²/4
Area of 2semicircles = 3.14(20)²/4
Area of 2semicircles = 3.14*400/4
Area of 2semicircles = 3.14*100
Area of 2semicircles = 314ft²
Area of the quarter circle = πd²/4 * 1/4
Area of the quarter circle = πd²/16
d = 2r
d = 2*20
d = 40ft
Area of the quarter circle = 3.14(40)²/16
Area of the quarter circle = 3.14*1600/16
Area of the quarter circle = 3.14*100
Area of the quarter circle = 314ft²
Area of the fountain = 314ft²+314ft²
Area of the fountain = 628ft²

KL = 5,34
From the given information JLK = 72°, JM = 14 and JML = 51°. The distance of KL is 5.34.
What are the trigonometric ratios?Trigonometric ratios for a right-angled triangle are from the perspective of a particular non-right angle.
In a right-angled triangle, two such angles are there which are not right angled(not of 90 degrees).
The slanted side is called the hypotenuse.
From the considered angle, the side opposite to it is called perpendicular, and the remaining side will be called the base.
It is given that
JLK = 72°
JM = 14
JML = 51°
tan51 = JL / 14
JL = 17.29
cos72 = KL / 17.29

A licorice rope is 7 inches long. If four 5th graders share the licorice equally amongst themselves, what length of licorice will each student get?
Answer:
1.4 Inches Each
Step-by-step explanation:
This problem is fairly simple. Just divide 7 by 5 and put the correct units(inches) with the answer.
length of licorice each student will get is 1.875 inches.
What is simplification?A mathematical expression gets simpler when it is transformed into an equivalent, frequently shorter statement. One strategy for promoting uniformity in job effort, cost, and time is procedure simplification. It lessens diversity and variation that is harmful, unwanted, or unneeded.
Given, A licorice rope is 7 inches long. If four 5th graders share the licorice equally amongst themselves.
Since every 5th grader is sharing the rope equally.
Thus everyone will get = 7/4
Every 5th grader will get = 1.875 inches
Therefore, every 5th grader will get 1.875 inches length of licorice.

Answer:
Length of smaller side = 15 inches
Length of bigger side = 36 inches
Length of hypotenuse = 39 inches
Step-by-step explanation:
Given:
Length of smaller side = a
Length of bigger side = (a + 21) inches
Length of hypotenuse = (a + 24) inches
Find:
Length of all side
Computation:
Using Pythagorean theorem
Hypotenuse² = Base² + Perpendicular²
(a+24)² = a² + (a+21)²
a² + 576 + 48a = a² + a² + 441 + 42a
a² - 6a - 135 = 0
(a-15)(a+7)
So
a = 15 inches a = -7 inches
So,
Length of smaller side = a = 15 inches
Length of bigger side = (a + 21) inches = 15 + 21 = 36 inches
Length of hypotenuse = (a + 24) inches = 15 + 24 = 39 inches
