Step-by-step explanation:
√(6+x−x²)=9
the domain :
6+x-x² ≥ 0
(3-x)(2+x) ≥0
-2 ≤ x ≤ 3
problem solving:
√(6+x−x²)=9
6+x−x²=81
-x²+x+6-81 = 0
-x²+x-75 = 0
x²-x+75 = 0
D = 1² -4(1)(75) = 1-300 = -299

30 / ( 30 + 10 ) = 48 / x.
30 / 40 = 48 / x
3 / 4 = 48 / x
3 * x = 4 * 48
x = 4 * 48 / 3
= 4 * 16
x = 64
To tie-dye one T-shirt 3/8 cup of dye is needed. the table shows the number of cups of each color of dye in Mr. Galvez's art class. how many t-shirts can be made using only orange dye?
Amount of Dye
red: 12
orange:3/4
Answer:
Two shirts can be made
Step-by-step explanation:
We do have 3/4c of orange dye.
We do require 3/8c per T-shirt.
But, using math, it can be shown that 3/4c=2×3/8c
Looking at it this way: 3/4c = 2x3/8c
Where the 2 is the number of T-shirts we can produce.
It is easy now to see: 3/4c = 2x3/8c = 6/8c
So: 34c=68c=34c→ and all of this is orange dye
Find the area of this figure to the nearest hundredth. Use 3.14 to approximate pi.
(The figure is a right triangle conjoined to a semi-circle. The semi-circle's diameter is 8, the triangle's base is 6, the triangle's height is 8. )
Answer:
49.12 square units
Step-by-step explanation:
Area of triangle = [tex]\dfrac{1}{2}*base *height[/tex]
[tex]=\dfrac{1}{2}*6*8=3*8 = 24 \ sq.units[/tex]
Circle:
d = 8 units
r = 8/2 = 4 units
[tex]Area \ of \ semicircle = \dfrac{1}{2}\pi r^{2}\\[/tex]
[tex]=\dfrac{1}{2}*3.14*4*4=3.14*2*4= 25.12 \ sq.units[/tex]
Area of the figure = area of triangle +area of semicircle
= 24 + 25.12
= 49.12 sq. units

r =
Submit
Answer:
[tex]r=-18[/tex]
Step-by-step explanation:
1) Combine like terms
[tex]18r-10r-20r+2r+9r=18\\-r=18[/tex]
2) Divide both sides of the equation by the same term
[tex]-r=18\\\frac{-r}{-1} =\frac{18}{-1}[/tex]
3) Simplify
a. Cancel terms that are in both the numerator and denominator
[tex]\frac{-r}{-1} =\frac{18}{-1} \\r=\frac{18}{-1}[/tex]
b. Divide the numbers
[tex]r=-18[/tex]
Answer: -18
Step-by-step explanation:
18r - 10r - 20r + 2r + 9r = 18
-r = 18
18/-1
r = -18

Adam won 80 super bouncy balls playing the bean bag toss at his school's game night. Later, he gave four to each of his friends. He only has 4 remaining. How many friends does he have?
Answer:
