pls help no wrong answers pls
Answer:
a, b, e
Step-by-step explanation:
It is proportional since it goes at the same rate on the x and y
It has a rate of 8.5 since 17/2=8.5
at the rate of 8.5 y per one x then 4 8.5's would make 34

Answer:
1) (x + 12)²+(y+6)²= 28
comparing above equation with(x-h)²+(y-k)²=r²
we get
r=√28
h=-12
k=-6
;.centre=(-12,-6)
radius =√28 units
2) x²+(y+7)²=15
comparing above equation with(x-h)²+(y-k)²=r²
we get
r=√15
h=0
k=-7
;.centre=(0,-7)
radius=√15 units
3) (x + 4)²+(y - 1)² = 4
comparing above equation with(x-h)²+(y-k)²=r²
we get
r=√4=2units
h=-4
k=1
;.centre=(-4,1)
radius=√2units
4) (x+3)²+(y-1)²= 8
comparing above equation with(x-h)²+(y-k)²=r²
we get
r=√8=2√2units
h=-3
k=1
;.centre=(-3,1)
radius=2√2units
Mai has a dome paperweight that she can use as a magnifier. The paperweight is
shaped like a hemisphere made of solid glass, so she wants to design a box to keep it in
so it won't get broken. Her paperweight has a radius of 3 cm.
What should the dimensions of
the inside of box be so the box is
as small as possible?
What is the volume of the box?
If the radius is 3, what's the diameter?
Whats 6x-5+2x=3x-2x+9?
Answer:
X=2
Step-by-step explanation:
first combine like terms
subtract the x
add 5
lastly divide by 7
Veronica bought a pack of 50 CDs. She gave 8 to her friend, Leslie. Then she made 6 equal sets of CDs. How many CDs are in each set?
Answer:

what's the surface area ratio & the volume ratio??
please help me ASAP!!
Answer:
Step-by-step explanation:
Volumes of two spheres A and B = 648 cm³ and 1029 cm³
Things to remember:
1). Scale factor of two objects = [tex]\frac{r_1}{r_2}[/tex] [[tex]r_1[/tex] and [tex]r_2[/tex] are the radii of two circles]
2). Area scale factor = [tex]\frac{(r_1)^2}{(r_2)^2}[/tex]
3). Volume scale factor = [tex]\frac{(r_1)^3}{(r_2)^3}[/tex]
Volume scale factor Or Volume ratio = [tex]\frac{V_A}{V_B}[/tex]
[tex]\frac{(r_1)^3}{(r_2)^3}= \frac{648}{1029}[/tex]
[tex]\frac{r_1}{r_2}=\sqrt[3]{\frac{648}{1029} }[/tex]
[tex]\frac{r_1}{r_2}=\frac{6(\sqrt[3]{3})}{7(\sqrt[3]{3})}[/tex]
[tex]\frac{r_1}{r_2}=\frac{6}{7}[/tex]
Therefore, scale factor = [tex]\frac{r_1}{r_2}=\frac{6}{7}[/tex]
≈ 6 : 7
Area scale factor Or area ratio = [tex](\frac{r_1}{r_2})^2=(\frac{6}{7})^2[/tex]
= [tex]\frac{36}{49}[/tex]
≈ 36 : 49
Volume scale factor or Volume ratio = [tex]\frac{648}{1029}[/tex]
= [tex]\frac{216}{343}[/tex]
≈ 216 : 343

Answer:
A
Step-by-step explanation:
Answer:
A) (4,8) is the correct answer.
Step-by-step explanation:
Step: Solvey=2xfor y:
y=2x
Step: Substitute2xforyiny=x+4:
y=x+4
2x=x+4
2x+−x=x+4+−x(Add -x to both sides)
x=4
Step: Substitute4forxiny=2x:
y=2x
y=(2)(4)
y=8(Simplify both sides of the equation)

write the equation (3,5) in standard form
Answer:
We can write out 3! (three factorial) as 3x2x1, and we can write out 5! as 5x4x3x2x1. This means that, since 3x2x1 is on the top and the bottom of the fraction, it cancels out. This leaves us with 1 on top, and 4x5=20 on the bottom.

Help me with this plz
Answer:
[tex]g = \frac{ x - 2}{3} [/tex]
Answer: g=x-2/3
Step-by-step explanation:
When it says make g the subject it means make it on it's own in front of the '=' sign.
To make g the subject, you have to do the inverse to 'undo' the equation.
So, instead of adding 2, you have to take away 2 from x. This would now look like this:
x-2=3g
In algebra, when a number is next to a letter it means times. So instead of multiplying g by 3, you would have to divide x-2 by 3. This would now look like this:
x-2/3=g
