Answer: 1 gallon
Step-by-step explanation:
white: red: yellow
4 : 3 : 2
total units: 9 units
total amount: 3 gallons
one unit: 3/9
= 1/3
no of units of red: 3 units
amount of paint needed: 1/3 x 3
= 1 gallon
Answer:
1/20
Step-by-step explanation:
In Scarlette grade 1/5 of the students have a sister.
Of the students who have a sister 1/4 also have a brother
Therefore fraction if students in Scarlet's grade who had both brothers and sister can be calculated as follows
= 1/5 ×1/4
= 1/20
<span>Sin(-x) = -sin x for all values of x, IT IS TRUE
Because sinx is an odd function</span>
Hello :
<span>(x² - 4x )+( y² - 4y) - 73 = 0
</span>(x² - 4x+4-4 )+( y² - 4y+4-4) - 73 = 0
(x² - 4x+4)-4 +( y² - 4y+4)-4 - 73 = 0
(x-2)² +(y-2)² = 9²
<span>the radius is : 9</span>
The drawing is missing, so i have attached it.
Answer:
24 yards
Step-by-step explanation:
From the image, we can see that AB and DE are both adjacent sides of their respective triangles.
While, CE and BC are both opposite sides of their respective triangles
Now, from your side, x is the distance to the island.
So, from ratio of similar triangles, we can find x.
Thus;
8/x = 3/9
Cross multiply to get;
8 × 9 = 3x
3x = 72
x = 72/3
x = 24
Thus, distance from your side to the island is 24 yards
