Answer:
4.5 is the range
Step-by-step explanation:
Ok, so it's asking for range, Range means The Highest number minus the smallest number.
What is the highest number? it's "2.3"
What is the lowest number? it's "-2.2"
so subtract those numbers and you get your answer!
Wait... why is the range 4.5? well, you do 2.3-(-2.2) when there are 2 minuses, you switch it to a + sign. so, 2.3+2.2=4.5!

An infinite geometric series contains consecutive terms 262.4, 209.92, 167.963 and the sum is 1640. What is the first term?
Answer:
328
Step-by-step explanation:
[tex]\frac{a}{1-r}[/tex] is the equation for the sum of an infinite geometric series, where [tex]a[/tex] is the first term of the infinite geometric series, and r is the common ratio between the terms. Here, we can find the common ratio between any consecutive terms. [tex]\frac{209.92}{262.4} = \frac{4}{5}[/tex]
Therefore, [tex]\frac{a}{1-\frac{4}{5}} = 1640[/tex].
This simplifies to [tex]5a = 1640[/tex]
Therefore, [tex]a = 328[/tex]
How many hectograms are in 45 centigrams?

0.0045 hectograms are in 45 centigrams
Step-by-step explanation:
Two step equations x−17/3=−3
Answer:
[tex]\boxed {x = \frac{8}{3}}[/tex]
Step-by-step explanation:
Solve for the value of [tex]x[/tex]:
[tex]x - \frac{17}{3} = -3[/tex]
-Add both sides by [tex]\frac{17}{3}[/tex] and convert [tex]-3[/tex] to a fraction [tex]-\frac{9}{3}[/tex]:
[tex]x - \frac{17}{3} + \frac{17}{3} = -3 + \frac{17}{3}[/tex]
[tex]x = -\frac{9}{3} + \frac{17}{3}[/tex]
-Since both [tex]-\frac{9}{3}[/tex] and [tex]\frac{17}{3}[/tex] have the same denominator, then you would add the numerators:
[tex]x = \frac{-9 + 17}{3}[/tex]
[tex]\boxed {x = \frac{8}{3}}[/tex]
Therefore, the value of [tex]x[/tex] is [tex]\frac{8}{3}[/tex].
Write an equation of the line that passes through (2,−5) and is parallel to the line 2y=3x+10
Step-by-step explanation:
Divide two on both sides to get rid of it and the make the equation in the form y = mx + c
[tex] \frac{2}{2} y = \frac{3}{2} x + \frac{10}{2} [/tex]
y = 3/2x + 5
since both lines are parallel they must have the same gradient which is 3/2
y = 3/2x + c
All you have to do now is to replace x and y with (2, -5) to find c
x = 2
y = -5
-5 = 3/2 × 2 + c
-5 = 3 + c
c = -5-3
c = -8
[tex]y = \frac{3}{2} x - 8[/tex]

The lengths of the two diagonals of a rhombus are 6 cm and 8 cm. Find the length of its perimeter (in
cm)
Answer:
The perimeter of the rhombus is 20 cm
Step-by-step explanation:
Perimeter of a Rhombus
Given the lengths of the two diagonals of a rhombus, let's call them a and b, the perimeter of the rhombus is given by:
[tex]P=2\sqrt{a^2+b^2}[/tex]
The values of the diagonals provided by the question are a=6 cm, b=8 cm, thus the perimeter is:
[tex]P=2\sqrt{6^2+8^2}[/tex]
[tex]P=2\sqrt{36+64}[/tex]
[tex]P=2\sqrt{100}=2*10[/tex]
[tex]P=20\ cm[/tex]
The perimeter of the rhombus is 20 cm
Triangle MNO has vertices with coordinates (–8, 2), (–5, 5), and (5, – 2).
Which of these equations represents the line that passes through point N and is perpendicular to the line passing through points O and M?
y = x + 3
y = x - 3
y = -x + 3
y = -x - 3
Answer:
i think its c
Step-by-step explanation:
The equation of a straight line is represented as: [tex]y = mx + c[/tex]
The equation of the line is: [tex](c)\ y = -x +3[/tex]
The coordinates are given as:
[tex]M = (-5,5)[/tex]
[tex]N = (5,-2)[/tex]
[tex]O = (-8,2)[/tex]
First, we calculate the slope of line MO using:
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
So, we have:
[tex]m = \frac{2-5}{-8--5}[/tex]
[tex]m = \frac{-3}{-3}[/tex]
[tex]m = 1[/tex]
The line that passes through N is perpendicular to MO.
This means that, the slope (m2) of the line is:
[tex]m_2 = -\frac 1m[/tex]
So, we have:
[tex]m_2 = -\frac 1{1}[/tex]
[tex]m_2 = -1[/tex]
The equation of the line is then calculated as:
[tex]y = m_2(x - x_1) + y_1[/tex]
Where:
[tex]m_2 = -1[/tex]
[tex]N = (5,-2)[/tex] --- [tex](x_1,y_1)[/tex]
So, we have:
[tex]y = -1(x -5) - 2[/tex]
[tex]y = -x +5 - 2[/tex]
[tex]y = -x +3[/tex]
Hence, the equation of the line is: [tex](c)\ y = -x +3[/tex]

[tex]\dfrac{4}{3}[/tex]
[tex]y=\dfrac{3}{4}-6[/tex]
Step-by-step explanation:
(a) [tex]3x-4y=24[/tex]
Let [tex]x=0[/tex]
[tex]0-4y=24\\\Rightarrow y=-6[/tex]
Let [tex]y=0[/tex]
[tex]3x-0=24\\\Rightarrow x=8[/tex]
Two coordinates are (0, -6) and (8, 0)
(b) Slope is given by
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}\\\Rightarrow m=\dfrac{0-(-6)}{8-0}\\\Rightarrow m=\dfrac{3}{4}[/tex]
The slope of the equation is [tex]\dfrac{4}{3}[/tex]
(c)
[tex]3x-4y=24\\\Rightarrow 4y=3x-24\\\Rightarrow y=\dfrac{3}{4}-6[/tex]
The slope intercept form of the equation is [tex]y=\dfrac{3}{4}-6[/tex]
