Step-by-step explanation:
A=2(wl+hl+hw)
A=2 ( (2)(5)+(2)(5)+(2)(2) )
A= 2(24)
A=48
f(x) = 8/x
g(x) = x^2 + 2
To figure this out, utilize the context clues given.
If you're meant to first find g of x (x currently not being a number), the equation should stay the same. Thus, you need to find f of g, or the equation that you were given.
If f(x) were to be 8/x, then x^2 + 2 would be inputted into the denominator, as dictated above.
Hope this helps!
Let x be the number of bags of Nature's Recipe Venison Meal & Rice Canine 20 percent protein, y be the number of bags of Nutro Max Natural Dog Food 27 percent protein and z be the number of bags of PetSmart Premier Oven Baked Lamb 25 percent protein a dog breeder buys. He wants to make 300 pounds of a mix. Then
20x+17.5y+30z=300.
Now
- in 20x pounds of Nature's Recipe Venison Meal & Rice Canine 20 percent protein is 0.2·20x=4x pounds of protein;
- in 17.5y pounds of Nutro Max Natural Dog Food 27 percent protein is 0.27·17.5y=4.725y pounds of protein;
- in 30z pounds of PetSmart Premier Oven Baked Lamb 25 percent protein is 0.25·30z=7.5z pounds of protein;
- in 300 pounds of mix containing 22 percent protein is 0.22·300=66 pounds of protein.
Then 4x+4.725y+7.5z=66.
You get a system
From the first equation Substitute it into the second equation:
Simplify it:
y must be divided by 20, then
- y=0, x=9, z=10-6=4;
- y=20, x=16, z is not a whole number;
- y=40, x=23, z is not a whole number;
- y=60, x=30, z=10-20-35<0;
- thus, all other possible z will be <0.
Answer: 9 bags with 1st mix, 0 bags with 2nd mix and 4 bags with 3rd mix.
Answer:
60
Step-by-step explanation:
Answer:
2a.
2b. 78
Step-by-step explanation:
For 2a, all the squares are similar and this shape forms a cube. Count the boxes for the length and width for 1 square to find the dimensions 3 for the width and 3 for the length. Find the area of that square by doing length*width which in this case is 3 x 3 = 9. Then multiply 9 x 6 because there are 6 squares and get an answer of 54.
For 2b, we know the dimensions for the rectangle 5cm will be the longer side and 3cm will be the shorter side. Find the area of one rectangle using length*width. For one rectangle we get 5 x 3 = 15. Next, we know the square will have sides of 3cm. Do length*width to get the area of one square which is equal to 9. Now that we have the areas for the squares and rectangles, multiply 15 (the area of one rectangle) by 4 because there are 4 similar rectangles. After doing this we get 60. Next do the same thing with squares but multiply by 2 because there are 2 squares. After doing this we get 60 + 18 for the surface area of the figure. 60 + 18 = 78.
