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.
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

What is the solution to this equation?
3x + 8 = 2x - 8
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 :
⤏ [tex] \sf{x = - 16}[/tex]
[tex] \red{ \boxed{ \boxed{ \tt{Our \: final \: answer : \boxed{ \underline{ \tt{x = - 16}}}}}}}[/tex]

Answer:
y=-2x+2
Step-by-step explanation:
Just follow the slope-intercept form formula-
Formula: y= mx+b
Key:
y = y-coordinate
m = slope
x = x-coordinate
b = y-intercept

Can a binomial be multiplied by a monomial such that the product is a monomial? If so, give an example.(1 point)
Yes. 0(2x+y)=0
No. A binomial can never be multiplied by a monomial such that the product is a monomial.
Yes. 1(2x+y)=2x+y
Yes. 2(2x+y)=4x+2y
No, you can’t multiply a monomial and binomial together and have a product of a monomial.

Step-by-step explanation:
Answer: t ≤ -4
Step-by-step explanation:
rearrange the problem 24-(-6*t)≤0 Pull out like factors :24 + 6t = 6 • (t + 4)
Divide both sides by 6 Subtract 4 from both sides t ≤ -4

The height of the cuboid is 6 cm.
The volume of the cuboid is 90 cm'.
What is the area of the shaded face?
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].

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
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.
What is the result when 2x 2 + 3x - 1 is subtracted from 4x 2+ 7x - 3?
Step-by-step explanation:
[tex] \tt{4 {x}^{2} + 7x - 3 - (2 {x}^{2} + 3x - 1)}[/tex]
While subtracting , the sign of each and every term of second expression changes.
⤏ [tex] \tt{4 {x}^{2} + 7x - 3 - 2 {x}^{2} - 3x + 1}[/tex]
Combine like terms. Like terms are those which have the same base. Only coefficients of like terms can be added or subtracted.
⤏ [tex] \tt{4 {x}^{2} - 2 {x}^{2} + 7x - 3x - 3 + 1}[/tex]
⤏ [tex] \tt{2 {x}^{2} + 4x - 2}[/tex]
[tex] \red{ \boxed{ \boxed{ \tt{Our \: final \: answer : \boxed{ \underline{ \tt{ \: 2 {x}^{2} + 4x - 2}}}}}}}[/tex]

Brookfield Furniture needs to ship 119 couches across the country. If they can fit 9 couches in each truck, how many couches will be in the partially full truck?
Answer:
2
Step-by-step explanation:
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
