Answer:
The number of Carmel muffins is 8 and the number of lemon muffins is 12.
Step-by-step explanation:
Melvin Marshall bought a total of 20 Muffins . Some were camel-glazed muffins and some were lemon. The Carmel muffins cost $3 each while the lemons cost $2.5 . The number of carmel muffins and lemon muffins can be calculated as follows
total number of muffin = 20
Let
a = number of carmel - glazed muffins
b = number of lemon muffins
a + b = 20.............(i)
The total cost
3a + 2.50b = 54................(ii)
Combine the equations
a + b = 20.............(i)
3a + 2.50b = 54................(ii)
a = 20 - b
insert the value of a in equation (ii)
3(20 - b) + 2.50b = 54
60 - 3b + 2.50b = 54
60 - 54 = 0.5b
0.5b = 6
divide both sides by 0.5
b = 6/0.5
b = 12
Insert the value of b in equation (i)
a + b = 20.............(i)
a + 12 = 20
a = 20 - 12
a = 8
The number of Carmel muffins is 8 and the number of lemon muffins is 12.
B: 100,000 combinations because if you have 5 digits, your equation is 10^5 which equals 100,000,
If 60% out of the 2,660 students are males, then
40% out of t<span>he same 2,660 students are females
Ten the number of females is 40% x 2660 = 0.4 x 2660 = 1,064 females</span>
Answer:
Find the reciprocal of the divisor
Reciprocal of
15/7 : 7/15
Now, multiply it with the dividend
So, 10/ 21 ÷ 15/7 = 10/21 × 7/15
= 10 × 7/ 21 × 15 = 70/ 315
After reducing the fraction, the answer is
2/9
Break it into squared and rectangles and find the area of those first then add it all together
For your square you would get 16 ft squared
For your rectangle you would get 32 ft squared
For your other rectangle you would get 32 ft squared as well
Then add those all together to get the full answer
80 ft squared
Hope this helps :)
