Choose the estimate closest to the length of a pen: 30cm, 160mm, or 16mm.
The estimate closest to the length of a pen is 160mm
How to estimate the closest length of a pen?Estimation is when we use approximate values in a calculation to give an approximate, predicted answer rather than an exact answer.
We can estimate some lengths and distances using approximate values for measurements.
For example, 16 cm is approximately the length of a pen.
Therefore, the estimate of a pen is 16 cm.
Since the length in cm is not in the option, we have to convert.
Hence,
1 centimetres = 10 millimetres
16 centimetres = ?
cross multiply
estimated length of a pen = 160 millimetres.
Therefore, the estimate closest to the length of a pen is 160mm

Two positive integers that differ by 9 are in the ratio of 8 to 11. What is the value of the smaller of the two numbers?
The numbers are 24 and 33 so the smaller one is 24
Answer:
24 and 33 are the numbers among which 24 is the smallest.
Step-by-step explanation:
Let one positive integer be x, then another will be x - 9
Solve:
[tex]\sf \dfrac{x-9 }{x} = \dfrac{8}{11}[/tex]
cross multiply
[tex]\sf 11x-99= 8x[/tex]
collect like terms
[tex]\sf 11x-8x = 99[/tex]
simplify
[tex]\sf 3x = 99[/tex]
divide both sides by 3
[tex]\sf x = 33[/tex]
As the integer is positive, x = 33, then another will be 33 - 9 = 24.

One way to simplify an expression containing trigonometric functions is to first write the expression in terms of sines and cosines only.
What is an expression?An expression can be defined as a mathematical equation which is used to show the relationship existing between two or more variables and numerical quantities.
The law of cosine.In order to determine the missing side length of a geometric figure with the adjacent and hypotenuse side lengths given, you should apply the law of cosine:
C² = A² + B² - 2(A)(B)cosθ
Similarly, the law of sine can be used to determine the missing side length of a geometric figure with the opposite and hypotenuse side lengths are given:
[tex]\frac{sinA}{a} =\frac{sinB}{b} =\frac{sinC}{c}[/tex]
In this context, we can reasonably infer and logically deduce that an expression containing trigonometric functions can be simplified by first writing the expression in terms of sines and cosines only.

Kim drew a map of Mississippi Rive. The scale was 5 centimeters represents 120 mikes. Th as tusk length is 2320 miles. What is actual length in centimeters of the Mississippi River?
The actual length of the river on centimetres is 97 centimetres
How to find the length of the Mississippi River using the scale?The scale was 5 centimetres represents 120 miles.
Therefore, on the scale
5 centimetres = 120 miles
Now, let's find the length in centimetres if the river is measured as 2320 miles.
120 miles = 5 centimetres
2320 miles = ?
cross multiply
actual length of the river in centimetres = 2320 × 5 / 120

The solution to the inequality is w ≥ 470 or w ≤ 530
How to determine the solution to the inequality?The given parameters are:
Number of words = 500
Absolute deviation = 30
Acceptable number of words = w
The absolute value inequality is represented as
|w - Number of words| ≥ Absolute deviation
So, we have
|w - 500| ≥ 30
Remove the absolute bracket
So, we have
w - 500 ≥ -30 or w - 500 ≤ 30
Add 500 to both sides of the inequality
So, we have
w ≥ 470 or w ≤ 530
Hence, the solution to the inequality is w ≥ 470 or w ≤ 530

In the given figure AB = AC, BAD = 50 and AD = AE. find the value of x
Answer:
[tex]x=25^o[/tex]
Step-by-step explanation:
Angle sum of a triangle: [tex]< A + < B+ < C=180^o\\[/tex]
Types of Triangles: Isosceles, Equilateral, Scalene
Given AB = AC are two sides of the big triangle, then ΔABC is Isosceles.
Isosceles triangles are defined to have two equal sides and two equal angles (opposite the congruent(equal) sides).
Also, since ABC is defined as a triangle, BC is a straight line, a.k.a., it is a [tex]180^o[/tex] angle. As the image shows, the line, AD creates a right angle on one side, therefore it creates a right angle([tex]90^o[/tex]) on the other side.
Back to Isosceles Triangles, AD = AE means ΔADE is isosceles and <ADE = <AED
Using the Angle sum formula of a triangle, you can fill in <A, <B, and <C with the following:
<A=[tex]50^o[/tex]
<B=<C=y [This is because <ADE = <AED]
[tex]50^o+2y=180^o\\2y=130^o\\y=65^o[/tex]
Now, this means that <ADE=[tex]65^o[/tex] and <ADC =[tex]90^o[/tex]
<x is better seen as <EDC
<EDC+<ADE=<ADC
Since we know <ADE is 65 and <ADC is 90, we can plug in these to the formula above.
[tex]x+65^o=90^o\\x=25^o[/tex]

The range of distance between Aaron and Clara is 7<d<23.
What is the triangle?Triangles are three-sided polygons with three vertices. The angles of the triangle are formed by connecting the three sides end to end at a point. The sum of the triangle's three angles equals 180 degrees. Every triangle has three sides and three angles, which may or may not be the same. In the case of a right triangle, the sides are given special names, with the side opposite the right angle being known as the hypotenuse and the other two sides being known as the legs.The range of possible distance from Aaron to Clara:
15+d > 8 ⇒ d > -78+d > 15 ⇒ d>715+8 > d ⇒ d < 23So, the range is: 7<d<23

x = .625 to change that to a decimal multiply by 100

one seventh times the absolute value of the quantity x minus 3 end quantity minus 2 equals 9
The solutions of "one seventh times the absolute values of the quantity x minus 3 minus 2 equals 9" is 80 and -74
The absolute value of the quantity x minus 3 = |x-3|
The one seventh time the absolute value of the quantity x minus 3 minus 2 equal to 9
Then the equation will become
(1/7)×|x-3|-2=9
Solve the equation
(1/7)×|x-3|-2= 9
(1/7)×|x-3|= 11
|x-3| = 11×7
|x-3|= 77
The absolute value equation will become
x-3= 77
x-3 = -77
Solve both equation
x-3=77
x= 80
x-3 = -77
x= -74
Hence, the solutions of "one seventh times the absolute values of the quantity x minus 3 minus 2 equals 9" is 80 and -74

The equation of the given function will be h=-0.096x+30.6. The mass will be 63.5 grams.
What is the equation of a line?A line is a one-dimensional shape that is straight, has no thickness, and extends in both directions indefinitely. The equation of line is given by,
y =mx + c
where,
x is the coordinate of the x-axis,
y is the coordinate of the y-axis,
m is the slope of the line, and
c is y-intercept.
1.) The slope of the given function will be,
Slope = (25.8 - 30.6) / (50 - 0) = -4.8/50 = -0.096
Now, substitute the values in the general linear equation,
h = -0.096x + c
30.6 = -0.096(0) + c
c = 30.6
Therefore, the equation of the given function will be h=-0.096x+30.6.
2.) Mass when the height is given as 24.5 cm, will be,
h = -0.096x + 30.6
24.5 = -0.096x + 30.6
24.5 - 30.6 = -0.096x
-6.1 = -0.096x
x = -6.1/-0.096
x = 63.5
Hence, the mass will be 63.5 grams.

HURRY IM TIMED Explain how to find the estimated sum of 5/8+2/9
Answer:
61/72
Step-by-step explanation:
first find the lowest common denominator - basically in this case the lowest number that goes into 8 and 9 - 8 x 9 which is 72, then
8 goes into 72 9 times so do 9 x the numerator (5)
9 x 5 = 45
Do the same for the second fraction, 9 goes into 72 8 times so do 8 x numerator (2)
8 x 2 = 16
Now add 45+ 16 = 61 ( this is your numerator)
and you keep the denominator (72) the same, so the answer is 61/72
