<span>Let Mia's age be m and her sister's age be x
m=2x+3
2x+3+x=less than 30
For greatest age we need to take largest number.
3x+3=29
x=26/3
But the options are all in whole numbers, so if
3x+3=27
then x =8</span>
Answer:
(x-4)^2 + (y-5)^2 = 20
Step-by-step explanation:
Rearrange the line equation of 5x - 2y + 6 = 0
So y = 5/2x +3
The y-intercept of the line equation is 3 as when x=0, y=3.
We know the Circle has the formula 
from the question but with the intercept, we can find the entire equation as the y-intercept is (0,3) so we can substitute it into the equation to find the full equations so:
This simplifies to:
= 
16 + 4 = 20 =
The answer is 20 so the equation of the circle is 
Answer:
9-4+(5x3)
Step-by-step explanation:
9-4+15
24-4
20
Answer:
$4000
Step-by-step explanation:
Given that :
Volume of cube = 8000 ft³
Charge per ft² = $10
Recall, volume of a cube = a³
Where a = edge
Hence,
a³ = 8000
Take the cube root of both sides
a = 20
Hence,
Volume = 20 * 20 * 20
The Area of the floor will be :
20 * 20 = 400 ft²
If charge per ft² = $10
400 ft² = ($10 * 400) = $4000
Answer:
90° - COD
Step-by-step explanation:
Because if it's complementary, the mystery angle and COD add up to 90°
