Answer:
g= 0,35
Step-by-step explanation:
We apply distributive property, we gather the g on one side and the integers on the other, it clears g
(0.10)(0.5) + 0.35g = 0.15(g + 0.5)
0,05 + 0,35g= 0,15 g + 0,075
0,35g -0,15 g= 0,075 - 0,05
0,20 g = 0,070
g= 0,070 / 0,20 = 0,35
Answer:Total amount contributed by principal = 4×128 = $512
Step-by-step explanation:
In 4 weeks, the school raised $2560 for a health and fitness awareness students collected donations in 5 days each week. Total number of days for which collection was made
= 5×4 = 20 days
The principal agreed to make one donation that was the same as the amount collected in a day each week. Let amount per day be x since all days are of equal amount, this means
A week = 5x
4weeks = 20x
20x = 2560
x = $128
The principal contributed $128 in each week
Total amount contributed by principal = 4×128 = $512
Answer:
292 inches^2
Step-by-step explanation:
So to start off this is a picture of the fish tank.
Next we will find the area of the bottom and top rectangles.
The side lenghts for those two is 7 and 8.
So the area of one is 56 and the area of 2 is 112 inches^2.
Now we will find the area of the left and right rectangles.
The side lenghts are 6 and 8.
So the area of 2 is 96 inches^2.
Now for the front and back rectangles.
The side lenghts for those two are 6 and 7.
So the area of both is 84 inches^2.
So after adding all the areas up the surface area is 292 inches^2.

- [Right Triangles Only] SOHCAHTOA
- [Right Triangles Only] sinθ = opposite over hypotenuse
Step-by-step explanation:
<u>Step 1: Identify</u>
Angle θ = 35°
Opposite Leg = <em>x</em>
Hypotenuse = 15
<u>Step 2: Solve for </u><em><u>x</u></em>
- Substitute [Sine]: sin35° = x/15
- Isolate <em>x</em>: 15sin35° = x
- Rewrite: x = 15sin35°
- Evaluate: x = 8.60365
- Round: x ≈ 8.6
