Answer:
Step-by-step explanation:
Let x represent the number of apples that she wants to buy. 
The grocery store sells apples for $1 each and mangos for $0.50 each. 
If Gabriella decided to buy 13 mangos, it means that the cost of buying x apples and 13 mangoes is expressed as 
x + 13 × 0.5 = x + 6.5
If she buy at least 19 apples, it means that 
x + 13 ≥ 19
x ≥ 19 - 13
x ≥ 6
Gabriella has $15 to spend. It means that 
x + 6.5 ≤ 15
x ≤ 15 - 6.5
x ≤ 8.5
Therefore, the maximum number of apples that she can buy is 8
 
        
             
        
        
        
Answer:
7/10 or 70%
Step-by-step explanation:
There has to be at least two T in each result of the simulation. This means you can also have 3 T's and 4 T's in the result.
These are the results that qualify as having at least two T's.
1. TTTT, 2. TTTT, 3. THTH, 4. HTTT, 5. TTTT, 7. HTHT, 9. THTH
That is 7 out of the 10 results which is 7/10 or 70%
 
        
             
        
        
        
Hello from MrBillDoesMath!
Answer:
72
Discussion:
Total Surface area = area of pyramid base + 4 ( area of triangular face) 
In our case this becomes
                                  4*4                               + 4(  (1/2) (4)(7) )  =
                                  = 16 + (2)(4)(7) 
                                  = 16 + 56        
                                  = 72
which is the first choice.  
Note: the area of a triangular face was computed using (1/2) b h, which in our case is
(1/2) (4) (7)
Thank you,
MrB

The height of cylinder b is 11 cm.
<h3>How to measure the volume of a cylinder?</h3>
The volume of the cylinder is related to the capacity of this geometric figure. Remember that the cylinder or circular cylinder is an elongated and rounded geometric solid.
The formula for the volume of a cylinder is given by:

Where:
- V: volume
 - π (Pi): 3
 - r: radius
 - h: height
 
In this case, as the cylinders are congruent, both will have the same radius, thus:
