Answer:
31\frac{1}{2}ft^2
Step-by-step explanation:
From the information given each of the three rectangular countertops has dimension 4\frac{3}{8} by 2\frac{2}{5} feet.
The area of a rectangular shapes is the product of the dimensions.
Each rectangular countertop has area;
4\frac{3}{8}\times 2\frac{2}{5}=\frac{35}{8}\times \frac{12}{5} =10\frac{1}{2}ft^2
Therefore the number of square feet tiles needed to cover all the countertops is D.
When talking about object measurements, we usually require they be positive.
A suitable domain is x > 0.
(and somewhat less than any substantial fraction of the Earth's dimensions. The numerical value will depend on the chosen units.)
Given: 11-pound mixture of peanuts, almonds, and raisins
Cost:
peanuts - 1.5 per pound
almonds - 3 per pound
raisins - 1.5 per pound
mixture:
twice as many peanuts as almond; total cost of mixture is 21.
a + p + r = 11 lbs
a + 2a + r = 11 lbs
3a + r = 11
r = 11 - 3a
1.5(2a) + 3a + 1.5r = 21
3a + 3a + 1.5r = 21
6a + 1.5r = 21
6a + 1.5(11-3a) = 21
6a + 16.5 - 4.5a = 21
6a - 4.5a = 21 - 16.5
1.5a = 4.5
1.5a/1.5 = 4.5/1.5
a = 3
almonds = 3 lbs
peanuts = 2a = 2(3) = 6lbs
raisins = 11 - 3a = 11 - 3(3) = 11 - 9 = 2 lbs
<span>My answer is: C. 6 lbs peanuts, 3 lbs almonds, 2 lbs raisins </span>
We are given equation 
.
We need to check the given table.
We have x=-2,-1,0,1,2 in the given table.
Plugging x=-2,-1,0,1,2 in the given equation
For x=-2
y = -3 (-2)^2 = -3(4) = -12
For x =-1
y = -3 (-1)^2 = -3(1) = -3
For x =-0
y = -3 (0)^2 = -3(0) = 0
For x =1
y = -3 (1)^2 = -3(1) = -3
For x =2
y = -3 (2)^2 = -3(4) = -12.
Therefore, correct table is
<h3> x y (x,y)</h3><h3>_____________</h3><h3> -2 -12 (-2,-12)</h3><h3> -1 -3 (-1,-3)</h3><h3> 0 0 (0,0)</h3><h3> 1 -3 (1,-3)</h3><h3> 2 -12 (2,-12).</h3><h3>________________</h3>
Answer:
y ≤ -8
Step-by-step explanation:
Since y is no more than -8, y must be less than or equal to -8.
