Answer: 5 days
Step-by-step explanation:
Let the number of pallets that the tan gerbil eat be x.
Since the brown gerbil eats 10 less than 4 times the number of pallets as the tan gerbil and eats 30 pallets pee day. This will be:
(4 × x) - 10 = 30
4x - 10 = 30
4x = 30 + 10.
4x = 40
x = 40/4
x = 10
The tan gerbil eats 10 pallets per day.
Both gerbil eats (30 + 10) = 40 gerbils per day.
Since the family has 200 pallets of food left, the number of days that they can feed both of the gerbils would be:
= 200 / 40
= 5 days
Answer:
White Kg, : 1.2
Green Kg, : 2
Black kg, : 2.8
Step-by-step explanation:
Ratio of amount of white, green and black tea is 3 : 5 : 7
This means, out of every 3+5+7= 15 parts, 3 parts are white tea, 5 parts are green tea and 7 parts are black tea.
We have to find, how many kilograms of each tea are needed to make a total of 6 kg of the mixture keeping the above ratio.
The formula to this is:
For example, for white tea, the concerned part in the ratio is 3, for green its 5 and for black tea its 7. Total parts remain 15 in three cases. The total amount is also fixed which is 6kg.
Using these values, we get<u>:</u>
Kilograms of White tea = kg
Kilograms of Green tea = kg
Kilograms of Black tea = kg
Answer:
<h2>L.A. = 384 cm²</h2><h2>S.A. = 640 cm²</h2>
Step-by-step explanation:
We have four congruent triangles with base b = 16cm and height h = 12cm.
The formula of an area of a triangle:
Substitute:
The latearal area:
For the surface area we need the area of a base.
The base is a square with side a = 16cm.
The area of the base:
The surface area:
Answer
x^2 = 7
so yeah u could've looked it up
You can do this a couple ways: either find g(6), then find f(x) of whatever that gives you (a 2-step process), or come up with a new expression to represent f(g(x)) and sub 6 into that (a 1-step process). I like the 1-step process more.
g(x) = 5x + 4; We want to sub this expression into every x in f(x) to get f(g(x)). If f(x) = x^2 + 5, then f(g(x)) = g(x)^2 + 5 = (5x + 4)^2 + 5. Now you can sub 6 into this equation and solve: f(g(6)) = (5(6) + 4)^2 + 5 = 1161.
