to find the number of couches in the partially filled truck, divide 119 by 9
119/9 = 13.2222
so 13 cars will contain 9 couches packed fully
number of trucks partially filled = 119 - (13 x 9) = 2

What is the total number of seconds it takes for the teacher to make 1 copy 2 copies 3 copies by how many seonds does the total time increse for each copy
Answers
Answer:
For 1 copy it takes 5 seconds, for 2 copy it takes 7 seconds, and for 3 copy it takes 9 seconds.
For each copy, it takes 2 seconds more.
Step-by-step explanation:
A teacher is making multiple copies of a 1-page homework assignment. The time it takes her in seconds is 2 times the number of copies she makes plus 3. What is the total number of seconds it takes for the teacher to make 1 copy? 2 copies? 3 copies? By how many seconds does the total time increase for each copy?
Let the number of copies represented by x and y is the time taken.
The time It takes her in seconds is 2 times the number of copies she makes plus 3.
So the required equation is [tex]y=2x+3[/tex].
To calculate the time taken for the first copy put x=1 in the above equation.
[tex]y=2(1)+3[/tex]
[tex]y=5[/tex]
To calculate the time taken for the first copy put x=2 in the above equation.
[tex]y=2(2)+3[/tex]
[tex]y=7[/tex]
To calculate the time taken for the first copy put x=3 in the above equation.
[tex]y=2(3)+3[/tex]
[tex]y=9[/tex]
Hence, For each copy, it takes 2 seconds more.
Guys i posted this question 100times plz answer i beg, thank you so much, plz show all the working
Answers
Answer:
x = 45.6
Step-by-step explanation:
NOTE: Please double-check my answer.
To find x, I used Sine Law.
[tex]\frac{x + 5}{sin65}[/tex] = [tex]\frac{x}{sin40}[/tex]
(x+5)sin40 = xsin65
xsin40+ 5sin40 = xsin65
xsin40 - xsin65 = -5sin40
x(sin40 - sin65) = -5sin40 (I factored out the "x")
x = [tex]\frac{-5sin40}{sin40 - sin65}[/tex]
x = [tex]\frac{-3.725565802}{0.74511316 - 0.826828679}[/tex]
x = 45.6

What is the solution to this equation?
3x + 8 = 2x - 8
Answers
Step-by-step explanation:
[tex] \tt{3x + 8 = 2x - 8}[/tex]
We want to get all the constants on the right hand side of the equation. So , Add 8 on both sides of the equation.
⤏ [tex] \tt{3x + 8 + 8= 2x - 8 + 8}[/tex]
⤏ [tex] \tt{3x + 16 = 2x}[/tex]
Move 2x to left hand side and change it's sign. Similarly , Move 16 to right hand side and change it's sign :
⤏ [tex] \tt{3x - 2x = - 16}[/tex]
Since , 3x and 2x are like terms , they can be added or subtracted. Subtract 2x from 3x :

The height of the cuboid is 6 cm.
The volume of the cuboid is 90 cm'.
What is the area of the shaded face?
Answers
Answer:
[tex]A=15\ cm^2[/tex]
Step-by-step explanation:
Given that,
The height of the cuboid = 6 cm
The volume of the cuboid = 90 cm²
We need to find the area of the shaded face.
The volume of a cuboid is given by the formula as follows :
[tex]V=A\times h[/tex]
A is area of the shaded face
Putting all the values,
[tex]A=\dfrac{V}{h}\\\\A=\dfrac{90}{6}\\\\A=15\ cm^2[/tex]
So, the area of the shaded face is [tex]15\ cm^2[/tex].
In 7th grade, the ratio of boys to girls is 6 to 7. If there are 143 students in 7th grade, how many are girls? Do NOT write a label. Just write the number.
Answers
Answer:
123 if your going to the nearest whole number
Step-by-step explanation:
Since
6 : 7 = X : 143
Then we know
6/7 = X/143
Multiplying both sides by 143 cancels on the right
143 × (6/7) = (X/143) × 143
143 × (6/7) = X
Then solving for X
X = 143 × (6/7)
X = 122.57142857143
Therefore
6 : 7 = 122.57142857143 : 143

Answer:
The diagonal stripes would require a total of 34 feet of tape.
Step-by-step explanation:
You have six hypotenuses, and you can use the Pythagorean theorem to get their lengths.
The total length of the two big diagonals then is:
2×√(36 + 36)
and the total length of the four small diagonals is
4 ×√(9 + 9)
so the total length is:
2√72 + 4√18
= 12√2 + 12√2
= 24√2
≈ 33.9
