For 34, since each diameter is in scientific notation , meaning that we have one number (1-9) followed by a decimal, we simply see which has the smallest power, which is cell C.

For 35, we multiply them out to get 0.83*10^2 (we subtract exponents when dividing). Since scientific notation is one integer from 1-9 followed by a decimal, we move 0.83 one place to the right and therefore remove one power from 10^2, getting 8.3*10

three fourths of the voters supported the bond measure .if there were 8000 voters,how many supported the bond measure.

Answers

We know that 3/4 of the voters supported the bond measure and that the total number of voters was 8000.
We can simply calculate the exact number of supporters by multiplying the supporting ratio by the total number of voters as follows:
number of supporters = (3/4) x 8000
= 6000 supporter

r= 2/3t +v , for t need answer and how u got it

Answers

You have R=2/3t + v
To solve for t, you have to first subtract v from both sides to get
        R - v = 2/3t
Next, you need to multiply both sides by 3/2 to get
        3/2R - v = t

A model of a famous statue is 1 1/2 inches tall. The actual statues is 3 3/4 feet tall. What is the ratio of the height of the model to the height of the actual statue in simplest form?

Answers

Final answer:

The ratio of the height of the model to the height of the actual statue, once converted to the same units, is 1:30. The actual statue at 3 3/4 feet tall is equivalent to 45 inches, and the model is 1 1/2 inches tall.

Explanation:

To find the ratio of the height of the model to the actual statue, we must first make sure both measurements are in the same units. Since the model is given in inches, we will convert the actual statue's height from feet to inches. There are 12 inches in a foot, so:

3 3/4 feet = 3.75 feet x 12 inches/foot = 45 inches.

Now we can set up the ratio of the model to the actual statue:

1 1/2 inches / 45 inches.

First, convert 1 1/2 inches to an improper fraction, which is (1 x 2 + 1)/2 = 3/2 inches. Our ratio is thus:

(3/2) inches / 45 inches = 3/90 = 1/30.

The ratio in simplest form is 1:30.

In solving a jigsaw puzzle, a move consists of joining two clusters, including clusters of just one piece. What is the minimum number of moves required to complete a two-thousand piece jigsaw puzzle that is separated into individual pieces?

Answers

Solution: As always, try to find a way of looking at the problem that makes the solution simple. In this problem, regardless of the current state of the puzzle, a move consists of combining two clusters into a single cluster. Therefore every move reduces the number of clusters by 1. Since we begin with 2000 clusters (the single pieces) and end with 1 cluster, we need \[2000-1=\boxed{1999}\] moves to complete the puzzle.

Answer:

1999 moves are required.

Step-by-step explanation:

Given is - In solving a jigsaw puzzle, a move consists of joining two clusters, including clusters of just one piece.

This means exactly [tex]n-1[/tex] moves are required to solve a jigsaw puzzle with n pieces.

Here, n = 2000

So, moves will be = [tex]2000-1=1999[/tex]

Hence. 1999 moves are needed to solve the puzzle.

Identify the translation rule on a coordinate plane that verifies that triangle A(-5,1), B(-2,7), C(0,1) and triangle A'(-6,0), B'(-3,6), C'(-1,0) are congruent.

Answer:

Triangle ABC translate 1 unit left and 1 units down to get the triangle A'B'C'. The rule of translation is

[tex](x,y)\rightarrow (x-1,y-1)[/tex]

Step-by-step explanation:

Given information: In triangle ABC, A(-5,1), B(-2,7), C(0,1). In triangle A'B'C', A'(-6,0), B'(-3,6), C'(-1,0).

Let the rule of translation be

[tex](x,y)\rightarrow (x-a,y-b)[/tex]

where, a is horizontal shift and b is vertical shift.

If a>0, then the graph shifts a units left and if a<0, then the graph shifts a units right.

If b<0, then the graph shifts b units up and if b>0, then the graph shifts b units down.

It is given that A(-5,1) and A'(-6,0).

[tex]A(-5,1)\rightarrow A'(-5-a,1-b)[/tex]

[tex]A'(-6,0)=A'(-5-a,1-b)[/tex]

On comparing both sides, we get

[tex]-6=-5-a\Rightarrow a=1[/tex]

[tex]0=1-b\Rightarrow b=1[/tex]

The value of a is 1 and value of b is 1. So, the rule of translation is

[tex](x,y)\rightarrow (x-1,y-1)[/tex]

Therefore the triangle ABC translate 1 unit left and 1 units down to get the triangle A'B'C'.

Step-by-step explanation:

y= 4x-9
and y=x-3


Also using transitive property

Answers

y = 4x - 9 and y = x-3 so the two right sides (4x-9 and x-3) must be equal

4x-9 = x-3

Let's solve for x

4x-9 = x-3
4x-9+9 = x-3+9 ... add 9 to both sides
4x = x+6
4x-x = x+6-x ... subtract x from both sides
3x = 6
3x/3 = 6/3 ... divide both sides by 3
x = 2

If x = 2, then y is...
y = 4*x - 9 = 4*2-9 = 8-9 = -1
which can also be found by 
y = x-3 = 2-3 = -1

So overall x = 2 and y = -1

We have the ordered pair (x,y) = (2,-1)

"The diameter of Pluto is 6/17 the diameter of Mars. Mars has 17/300 the diameter of Saturn. What fraction of the diameter of Saturn is the diameter of Pluto?"

Answers

1/50 This is just a matter of multiplying the two fractions you've been given together. You can make things easier for you by doing some reduction of the fraction before you multiply the numbers together. 6/17 * 17/300 = (6 * 17)/(17 * 300) Since you have a factor of 17 both top and bottom, they cancel each other out, giving (6 * 17)/(17 * 300) = 6/300 And since the greatest common factor for 6 and 300 is 6, you can divide both top and bottom by 6 giving 6/300 = 1/50 So Pluto as 1/50 of the diameter as Saturn.

If a car can travel 250 miles on 10 gallons of fuel, how many gallons are required to travel 1,325 miles?

Answers

1325                      250
-------          =        -------      
    x                           10

1325(10) = 250x

13250/250 = 250x/250

x = 53 

53 gallons are required to travel 1325 miles

hope this helps

Answer:

53 gallons of fuel

Step-by-step explanation:

Step 1: Set up a fraction given the data (Let "x" represent the distance in miles.)

[tex]\frac{10}{250} = \frac{x}{1325}[/tex]

Step 2: Divide the given values (The given values are 10 over 250. We are doing this because we need to know the difference between those two figures.) (Trick: For this case, all you need to do is cancel both zeros and the answer is 25)

[tex]\frac{10}{250}\\\\10 \div 250\\\\= 0.04[/tex]

Step 3: Multiply the result to the last value (Since we've found the difference between them by division, we will have to do the opposite operation in order to find the answer.)

[tex]1325 \times 0.04\\\\= 53[/tex]

Therefore, 53 is the amount of gallons of fuel needed.

The equation of a line is X+3Y=14
what is the y-intercept of the line?

Answers

X+3y=14
-x. -x
3y=-x+14
Divide them all by 3
Y=-x/3+14/3
Y-intercept= 1/3

Answer:  The required y-intercept of the given line is [tex]\dfrac{14}{3}.[/tex]  

Step-by-step explanation:  We are given to find the y-intercept of the following equation of a line :

[tex]x+3y=14~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)[/tex]

The slope-intercept form of the equation of a line is given by

[tex]y=mx+c,[/tex] where m is the slope and c is the y-intercept of the line.

From equation (i), we have

[tex]x+3y=14\\\\\Rightarrow 3y=-x+14\\\\\Rightarrow y=-\dfrac{1}{3}x+\dfrac{14}{3}.[/tex]

Comparing the above equation with the slope-intercept form, we get

[tex]\textup{y-intercept, c}=\dfrac{14}{3}.[/tex]

Thus, the required y-intercept of the given line is [tex]\dfrac{14}{3}.[/tex]

If you wanted an output of 7 for the rule y= -x+4, what would you need as an input?

Answers

y is output
if y=7 find x

7=-x+4
minus 4 both sides
3=-x
times -1
-3=x

your input will be -3
Final answer:

To get an output of 7 in the equation y = -x+4, the input value needed is -3.

Explanation:

To obtain an output of 7 for the linear equation y = -x + 4, we need to find the appropriate input value (x). The equation represents a straight line in the Cartesian plane, where 'y' is the dependent variable, and 'x' is the independent variable.

To solve for 'x' when y = 7, we simply substitute 7 for 'y' in the equation:

7 = -x + 4

Now, we need to isolate 'x' on one side of the equation. To do this, we can move the constant term (4) to the other side of the equation by subtracting it from both sides:

7 - 4 = -x

This simplifies to:

3 = -x

To solve for 'x', we multiply both sides by -1 to get:

x = -3

So, if you input x = -3 into the equation y = -x + 4, you will indeed get an output of 7:

y = -(-3) + 4

y = 3 + 4

y = 7

Therefore, an input of x = -3 will yield an output of 7 for the given equation.
