Answer:
46 of the sixth graders have green eyes.
Step-by-step explanation:
This question is asking what number of the 230 sixth graders have green eyes.
We know that one out of every five of them, or 20%, have green eyes.
1/5 = 0.2
If we multiply 0.2 by the total number of sixth graders, that leaves us with 46, meaning that 46/230 sixth graders have green eyes.
I hope this helps!

What is the density of the glass in 2.5 g/cm in kg/m
We are given:
Density of glass in g/cm³ = 2.5
Finding the density in kg/m³:
In converting 2.5 g/cm³ to kg/m³, we will first convert the g to kg
Converting the g to kg:
2.5 g/cm³ * 1
Since 1kg = 1000g, 1kg/1000g = 1
2.5 g/cm³ * 1kg / 1000g
the g in the numerator and the denominator will cancel out and we will get:
2.5 kg / 1000 cm³
Converting the cm³ to m³:
We know that 1 m³ = 10⁶ cm³
So, 10⁶ cm³ / 1 m³ = 1
Multiplying the density by 1
2.5 kg / 10³ cm³ * 1
2.5 kg / 10³ cm³ * 10⁶ cm³ / 1 m³
the cm³ in the numerator and the denominator will cancel out
2.5 * 10⁶ kg / 10³ m³
2.5 * 10³ * 10³ kg / 10³ m³
2.5 * 10³ kg / m³
2500 kg/m³

Answer:
(95/12,0)
Step-by-step explanation:
Answer:
(7.916, 0)
Step-by-step explanation:
In order to find the X-intercept, let y=0
12x + 5(0) = 95
12x = 95
95/12x = 7.91666...
Therefore, the x intercept is (7.916, 0)

What step can be taken to solve the equation 10x = 6 + 9x?
Answer:
subtract 9x from both sides
Step-by-step explanation:
10x = 6 + 9x
9x 9x
19x = 6
0.315789474 = x
.315 = x
Answer:
Subtract 9x from both sides of the equation.
Step-by-step explanation:
To put x by itself, you need to first put all like terms together. So in order to do this, you need to put 10x and 9x together. Since 9x is positive, you need to subtract 9x from both sides of the equation.
Here is how you completely solve the equation:

ABC dilated
Step-by-step explanation:
Given
Triangles ABC and DEF
Required
Determine the scale of dilation
First, we pick a side on ABC
[tex]AB = 6[/tex]
Pick a corresponding side on DEF
[tex]DE = 3[/tex]
The scale factor is then calculated as:
[tex]Scale\ Factor = \frac{DE}{AB}[/tex]
[tex]Scale\ Factor = \frac{1}{2}[/tex]
i.e. ABC was dilated by 1/2

How many inches are in 4 1/2 yards of fabric?
Answer: 162 inches
Step-by-step explanation: 4 yards are 144 inches and 1 yard alone is 36 when you divide it by half it’s 18. (144+18=162)
To convert [tex]4 \dfrac{1}{2}[/tex] yards of fabric to inches, multiply by 36.
Therefore, there are 162 inches in [tex]4 \dfrac{1}{2}[/tex] yards.
For the measurement, we know
1 yard = 36 inches
The given measurement is: [tex]4 \dfrac{1}{2}[/tex] yards
Convert it into an improper fraction,
[tex]4\dfrac{1}{2} = \dfrac{4 \times 2 + 1}{2} \\\\ = \dfrac{9}{2}[/tex]
Thus, [tex]4 \dfrac{1}{2}[/tex] yards can be written as [tex]\dfrac{9}{2}[/tex] yards.
Since 1 yard = 36 inches
Therefore,
(9/2) yards = (9/2)x36 inches
= 9 x 18 inches
= 162 inches
Hence,
The measurement [tex]4 \dfrac{1}{2}[/tex] yards are equivalent to 162 inches.

Find the value of X. Show your work.
Congruent triangle
Answer:
x = 3
Step-by-step explanation:
exterior angle of a triangle is equal to the sum of the measures of the two remote interior angles
97 + x = 64 + 27
x = 97 - 64 - 27 = 6
Answer: x=-6
you know that the interior angles of a triangle equal 180°. so lets find the remaining angle measure
64 + 27 = 91
180 - 91 = 89
so 89 is the third interior angle of the triangle. now let's find the exterior angle.
you know that the extended angle is supplementary; which means it will equal 180° as well. so lets add the third interior angle we just found and let's add it to the unknown expression:
89 + 97 + x = 180
186 + x = 180
-186 -186
x = -6
now it might seem wrong because x is negative and it feels like it should be positive. but let's check our answer.
64+27+89 does equal 180
and 97+(-6)+89 does equal 180
i hope this helps!
