On Monday a team of street sweepers cleaned 4 city blocks. Tuesday, the team cleaned 2 1/6 times as many blocks as on Monday. How many city blocks did the street sweepers clean on Tuesday?
1/5 is the answer :0000
There will be twelve and a half city blocks of the street sweepers clean on Tuesday.
What is a fraction?The numerator, which is found at the top of the fraction number, and the denominator, which is located at the bottom, are its two component components.
It is given that, four city blocks were cleaned by a crew of street sweepers on Monday. The crew cleaned 2 1/6 as many blocks on Tuesday as they did on Monday.
Suppose the number of city blocks the street sweepers cleaned on Tuesday will be x,
x = 4 + 2 1/6 × 4
x=4+13/6×4
x=12.6≈ 12 1/2
Thus, the street sweepers will clean twelve and a half city blocks on Tuesday.

If f(x) = 4x – 2 and g(x) = 5x – 3, what is g(f(2))?
Step-by-step explanation:
f(2) = 4(2) - 2
= 8 - 2
= 6
g(f(2)) = g(6)
g(6) = 5(6) - 3
= 30 - 3
= 27
g(f(2)) = 27

solve for x, UV and TV
We know that TV = TU + UV. Let's plug the values from the picture into our equation.
x + 25 = 9 + 2x + 28.
Let's combine like terms on the right side.
x + 25 = 2x + 37
Subtract 37 and x from both sides.
-12 = x
TV = x + 25 = -12 + 25 = 13
UV = 2x + 28 = 2(-12) + 28 = -24 + 28 = 4

Is Nora or Sofia correct? Explain your reasoning.
Answer:
Nora is correct
Step-by-step explanation:
Sophia used an appropriate method for computing the value of the repeating decimal fraction ...
0.1212_12
Close examination of the given decimal fraction shows that it is non-repeating, so is an irrational number. It cannot be represented by the ratio of integers.
Nora is correct in saying Sophia made a mistake.
___
Sophia depended on 100x -x cancelling some part of the fraction, so the result was a finite decimal. For repeating 2-digit fractions, this works well:
[tex]x=0.12\overline{12}\\100x=12.12\overline{12}\\100x-x=12.12\overline{12}-0.12\overline{12}=12\\x=12/99[/tex]
However, the decimal does not repeat, so this does not work:
100x = 12.1121112
100x -x = 12.1121112 -0.121121112 = 11.99099009900099... non-repeating
That is, the decimal part is not cancelled by Sophia's work, as we said above.
Find the distance between the points E(3,7)and(6,5).find the exact distance between the two points ?
Step-by-step explanation:
Let the distance points E(3,7) and F(6,5)
Distance between EF = √[(x2-x1)²+(y2-y1)²]→Formula
Here, x1 = 3, y1 = 7
x2 = 6 , y2 = 5
Now,
Put all the values in distance formulae:
AB = √[(6-3)²+(5-7)²]
= √[(4)²+(2)²]
= √[(4*4)+(2*2)]
= √[16+4]
= √[20] = 2√5 Units.
Answer:- Hence, the distance between two points E(3,7) and F(6,5) is 2√5 Units.

6x-2=7x+9 find x plz help
Answer:
[tex]x=-11[/tex]
Step-by-step explanation:
[tex]6x-2=7x+9[/tex]
Add 2 to both sides:
[tex]6x-2+2=7x+9+2[/tex]
[tex]6x=7x+11[/tex]
Subtract 7x from both sides:
[tex]6x-7x=7x+11-7x[/tex]
[tex]-x=11[/tex]
Divide both sides by -1:
[tex]\frac{-x}{-1}=\frac{11}{-1}[/tex]
[tex]x=-11[/tex]
Answer:
X= -11
Step-by-step explanation:
Simplifying
6x + -2 = 7x + 9
Reorder the terms:
-2 + 6x = 7x + 9
Reorder the terms:
-2 + 6x = 9 + 7x
Solving
-2 + 6x = 9 + 7x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-7x' to each side of the equation.
-2 + 6x + -7x = 9 + 7x + -7x
Combine like terms: 6x + -7x = -1x
-2 + -1x = 9 + 7x + -7x
Combine like terms: 7x + -7x = 0
-2 + -1x = 9 + 0
-2 + -1x = 9
Add '2' to each side of the equation.
-2 + 2 + -1x = 9 + 2
Combine like terms: -2 + 2 = 0
0 + -1x = 9 + 2
-1x = 9 + 2
Combine like terms: 9 + 2 = 11
-1x = 11
Divide each side by '-1'.
x = -11
Simplifying
x = -11

Find the general solution of the homogeneous system below. Give your answer as a vector.
x1 + 2x2 - 3x3 = 0
4x1 + 7x2 - 9x3 = 0
-x1 - 3x2 + 6x3 = 0
Answer:
Step-by-step explanation:
Given the system of homogeneous equations
x1 + 2x2 - 3x3 = 0 ................. 1
4x1 + 7x2 - 9x3 = 0 ................... 2
-x1 - 3x2 + 6x3 = 0..................... 3
First we will reduce the equation to two equations and two unknowns;
add equation 1 and 3;
2x2-3x2 +(-3x3+6x3) = 0
-x2 + 3x3 = 0
x2 = 3x3 .......... 4
Multiply equation 3 by 4 and add to equation 2;
equation 3 * 4 will give;
-4x1 - 12x2 + 24x3 = 0..................... 5
add equation 5 to equation 2;
7x2-12x2-9x3+24x3 = 0
-5x2 - 15x3 = 0 .......... 6
5x2 = 15x3
x2 = 3x3
Let x2 = k
From equation 4;
k = 3x3
x3 = k/3
substitute x2 = k and x3 = k/3 into equation 1 to get x1 in terms of k
From 1, x1 + 2x2 - 3x3 = 0
x1+2k-3(k/3) = 0
x1 +2k-k = 0
x1 +k = 0
x1 = -k
Writing the answer in vector form will give (x1. x2. x3) = (-k, k, k/3)
k(-1, 1, 1/3)
Hence the answer to the system of equation in vector form is k(-1, 1, 1/3) where k is any constant.

Height = √225
= 15
C) 2.5² = Base ² + 1.5 ²
Base² = 2.5 ²- 1.5²

F)25²= Base²+ 7²
Base² = 25²- 7²

=576
Base= √576
= 24

Suppose P(C) = 98%; P(D) = 88%; and P(C or D) = 33%.
Find P(C and D).
Can this really be a probability? If not, explain why not.
Answer:
[tex]P(C\ and\ D) = 153\%[/tex]
Step-by-step explanation:
Given
[tex]P(C) = 98\%[/tex]
[tex]P(D) = 88\%[/tex]
[tex]P(C\ or\ D) = 33\%.[/tex]
Required
[tex]P(C\ and\ D)[/tex]
In probability, the relationship between the given parameters and the required parameter is:
[tex]P(C\ and\ D) = P(C) + P(D) - P(C\ or\ D)[/tex]
Substitute values in the above formula
[tex]P(C\ and\ D) = 98\% + 88\% - 33\%[/tex]
[tex]P(C\ and\ D) = 153\%[/tex]
No, it can't be a probability
Because [tex]P(C\ and\ D) > 100\%[/tex]
