She is correct! This is so because 3 goes into .9 by .3 times. Hope this helped!

Yes, Cherri is correct. 0.9 ÷ 3 = 0.3. The dividend has a decimal, so the quotient has a decimal in the same place.

Hope I helped!

help asap im in a quiz, please show some sort of proof. and please dont say,¨ the answer is in the photo, and then send me a lin

The answer would be D i think because if the two angles are to equal 72, and one of the angles equals 42, 72-42= 30. to find x, you’d do 30/6 which equals 5. so x=5 and the angle measure would be 30

Can someone please do this for me?

Answer:

64°

Step-by-step explanation:

So supplement angles are equal to 180, so first our two angles added together will be 180:

x + x = 180

Now one of these angles is 6 greater than half:

x + (x/2 + 6) = 180

Then we will solve for x:

x + (x/2 + 6) = 180

x + x/2 + 6 = 180

x + x/2 = 174

$\frac{3}{2}$ x = 174

x = 116

Plug it back in:

x + (x/2 + 6) = 180

x/2 + 6

(116)/2 + 6

To check:

116 + 64 = 180 ✓

What is the equation of the graphed line written in standard form?

liraira [26]

Answer:

The last one 5x-3y=15 This is the same as y= (5/3)x -5

Step-by-step explanation:

5x-3y=15

Move 5x to the right (becoming negative)

-3y = -5x +15

Divide everything by - 3

y= (5/3)x -5

y intersect= -5 ( line crosses y coordinate at -5)

Slope = 5/3 From -5 you start counting (5 up,3 right,5 up,3 right.... OR 5 down,3 left,5 down,3 left........)

What is the center and radius of the circle? (x-3)2 + y² = 4

Kipish [7]

Answer:

center = (3, 0)

radius = 2

Step-by-step explanation:

Standard equation of a circle: $\sf (x-h)^2+(y-k)^2=r^2$

(where (h, k) is the center of the circle and r is the radius)

Given equation:

$\sf (x-3)^2+y^2=4$

Rewrite in standard form:

$\sf \implies (x-3)^2+(y-0)^2=2^2$

Therefore

center = (3, 0)
radius = 2
