4. Of the devices you used in this lab, which has the most digits of precision?
graduated cylinder
meter stick
thermometer
triple-beam balance
Answer:
meter stick
Step-by-step explanation:
The precision of a measuring instrument refers to its ability to measure very small increments.
For instance, the meter rule can measure lengths to a precision of about ±0.1cm. Hence, the smaller the increment that a measuring instrument can measure, the more precise the measuring instrument is.

Point Q lies on segment ST, where point S is located at (- 3, - 3) and location of point T is unknown. If SQ : QT = 4 : 3, and point Q is located at (3, 0) on the segment ST, select a place on the coordinate grid to plot point T and name its coordinate.
Answer:
The location of point T is [tex]\vec T = (7.5, 2.25)[/tex]. Graph is included at the end of the explanation as attachment.
Step-by-step explanation:
The SQ : QT ratio means that there are 4 units of SQ for each 3 units of QT. Vectorially speaking, we notice that:
[tex]\overrightarrow {SQ} = \frac{4}{7}\cdot \overrightarrow {ST}[/tex] (Eq. 1)
[tex]\overrightarrow{QT} = \frac{3}{7}\cdot \overrightarrow {ST}[/tex] (Eq. 2)
Now, we eliminate [tex]\overrightarrow{ST}[/tex] by equalizing (Eq. 1) and (Eq. 2):
[tex]\frac{7}{3} \cdot \overrightarrow{QT} = \frac{7}{4}\cdot \overrightarrow{SQ}[/tex] (Eq. 3)
From Linear Algebra, we know that:
[tex]\frac{7}{3}\cdot (\vec T - \vec Q) = \frac{7}{4}\cdot (\vec Q-\vec S)[/tex] (Eq. 3b)
And we clear [tex]\vec T[/tex]
[tex]\frac{7}{3}\cdot \vec T -\frac{7}{3}\cdot \vec Q = \frac{7}{4}\cdot \vec Q -\frac{7}{4}\cdot \vec S[/tex]
[tex]\frac{7}{3}\cdot \vec T = \frac{49}{12}\cdot \vec Q - \frac{7}{4}\cdot \vec S[/tex]
[tex]\vec T = \frac{3}{7}\cdot \left(\frac{49}{12}\cdot \vec Q-\frac{7}{4}\cdot \vec S\right)[/tex]
[tex]\vec T = \frac{7}{4}\cdot \vec Q-\frac{3}{4}\cdot \vec S[/tex]
If we know that [tex]Q(x,y) = (3, 0)[/tex] and [tex]S(x, y) = (-3,-3)[/tex], then we have that [tex]T(x,y)[/tex] is:
[tex]\vec T = \frac{7}{4}\cdot (3, 0) - \frac{3}{4}\cdot (-3, -3)[/tex]
[tex]\vec T = \left(\frac{21}{4}, 0 \right) + \left(\frac{9}{4},\frac{9}{4}\right)[/tex]
[tex]\vec T = \left(\frac{21+9}{4},\frac{0+9}{4} \right)[/tex]
[tex]\vec T = \left(\frac{15}{2}, \frac{9}{4}\right)[/tex]
[tex]\vec T = (7.5, 2.25)[/tex]
At last we plot the segment with all points described on statement. We can check the result in the attachment set below.
How many four-digit counting numbers are not multiples of 5?
Answer:
1000 to 9999 are all of the 4-digit counting numbers
1 to 9999 gives 9999 counting numbers, but we are leaving out 999 of them
9999-999=9000 counting numbers that are 4-digit numbers
9000-1800=7200 4-digit numbers that are not multiples of 5
Step-by-step explanation:
There are 7,000 four-digit counting numbers that are not multiples of 5.
What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.com
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
To find the number of four-digit counting numbers that are not multiples of 5, we need to find the total number of four-digit counting numbers and then subtract the number of four-digit counting numbers that are multiples of 5.
There are 9 choices for the first digit (it cannot be 0, since we are looking at four-digit numbers), and 10 choices for each of the remaining three digits (they can be 0-9).
So, the total number of four-digit counting numbers is:
9 × 10 × 10 × 10
= 9,000
To find the number of four-digit counting numbers that are multiples of 5, we need to consider the last digit.
Since a number is a multiple of 5 if and only if its last digit is 0 or 5, there are 2 choices for the last digit.
The first three digits can be any of the 10 digits, so there are:
10 × 10 × 10 × 2 = 2,000
four-digit counting numbers that are multiples of 5.
Therefore, the number of four-digit counting numbers that are not multiples of 5 is:
9,000 - 2,000 = 7,000
Thus,
There are 7,000 four-digit counting numbers that are not multiples of 5.

Solve 8x-3y=17 for y
Answer:
y= 8 /3 x+ −17 /3
Step-by-step explanation:
Step 1: Add -8x to both sides.
Step 2: Divide both sides by -3.
Hope this helped!
Have a great day :)
Answer:
y= 17/3 - 8/3x
Step-by-step explanation:
subtract 8x from both sides and get -3y = 17- 8x. Next divide everything by -3 (because it’s the number in front of Y) making it Y= 17/3 -8/3x (were left with big numbers because neither 17 or 8 can be divided by 3)

The perimeter of a rectangle is represented by the expression LaTeX: 2\left(3x+1\right)+2x2 ( 3 x + 1 ) + 2 x. Which statements explain correctly what each part of the expression represents? Select all that apply. One side of the rectangle measures LaTeX: x x One side of the rectangle measures LaTeX: 3x 3 x One side of the rectangle measures LaTeX: 3x+1 3 x + 1 LaTeX: x x is the coefficient in each term that represents the number of sides in a rectangle 2 is the coefficient in each term that represents 2 lengths and 2 widths in a rectangle One side of the rectangle measures LaTeX: 2x
Answer:
Step-by-step explanation:
Perimeter of a rectangle = 2(L+W)
L is the length of the triangle
W is the width
If the perimeter of a rectangle is represented by the expression [tex]2\left(3x+1\right)+2[/tex]
In order to know what wat each part represents, we will rewrite the given equation in the form 2(L+W).
Given
[tex]2\left(3x+1\right)+2x[/tex]
Perimeter of a rectangle
[tex]2L+2W[/tex]
Compare the given function with the perimeter to get L and W
[tex]L = 3x+1 \ and \ W = x[/tex]
Hence the following statements explain correctly what each part of the expression represents
- One side of the rectangle measures x (the length)
- One side of the rectangle measures 3x + 1 (the width)
- 2 is the coefficient in each term that represents 2 lengths and 2 widths in a rectangle.

Daniel is currently 26 years older than his son. In 6 years he will be 3 times older than his son. How old are both of them now?
Answer:
Son's age=7
Daniel's age=33
Step-by-step explanation:
d = s + 26
d + 6 = 3(s + 6)
Substitute!
s + 26 + 6 = 3s + 18
Simplify and distribute:
s + 32 = 3s + 18
Subtract s:
32 = 2s + 18
Subtract 18:
14 = 2s
Divide by 2:
7 = s
d = 7 + 26
d = 33
Use five different colors to paint the four rectangles A, B, C and D shown in the figure. No two rectangles sharing an edge can be the same color. How many ways are there to color the rectangles?
Answer:
260 ways
Step-by-step explanation:
There are 3 scenarios.
Scenario #1, all colors used are different. A, B, C, and D each have their own individual color.
In this case, there would be 5x4x3x2=120 ways for this to happen.
(Since each color is different, after one is chosen there are only n-1 colors left, hence why it is 5x4x3x2)
Scenario #2, EITHER A&C OR B&D are the same color (Diagonal rectangles share no edges so they share a color).
In this case, there would be 2(5x4x1x3)=120 ways for this to happen. (Since we have two options, either A&C or B&D share a color, we multiply (5x4x1x3) by two to represent both options. Since the diagonal pairs must share one color, if, for example, A's color has been chosen from 5 options, C has only 1 option to choose from because it MUST match A's color)
Scenario #3, BOTH A&C AND B&D are the same color, meaning only 2 colors are used.
In this case, there would be 5x4x1x1=20 ways for this to happen.
(If A is already one color, B must choose a color from the remaining 4 options, C must match A so it has 1 option, similarily D must match B so it also has only 1 option, hence 5x4x1x1)
Now we add up all possible scenarios.
120+120+20=260 ways

[tex]-12-60\\-72[/tex]
therefore, [tex]-72= -72[/tex]
d)
[tex]\frac{1+2}{4} \\\frac{3}{4}[/tex]
[tex]1-\frac{1}{4} \\\frac{4}{4} -\frac{1}{4}\\\frac{3}{4}[/tex]
therefore, [tex]\frac{3}{4} = \frac{3}{4}[/tex]

The sum of three consecutive integers is 71 less than the least of the integers. Find the integers.
Answer:
-37, -36, -35
Step-by-step explanation:
x+x+1+x+2=x-71
3x+3=x-71
2x=-74
x=-37
So x=-37, x+1=-36, x+2=-35
Add these three numbers and you get -108 which is 71 less than -37

Answer:
h = -0.0166t^2 + 30.
Step-by-step explanation:
The graph of the flight is a parabola which opens down and is symmetrical about the y axis, passes through the x axis at -42.5 and 42.5 and has a vertex at (0, 30).
So we have -a(t^2) + 30 = 0 where t is the time
(42.5)^2 * -a = -30 (42.5 as its 1/2 * 85).
a = 30/2806.25
= 0.01661
So the equation is height h = -0.0166t^2 + 30
