Answer:
5 dollars
Step-by-step explanation:
Let's call the price of a package of pens n, and the cost of a box of paper r.
3n+r=26
2n+7r=49
Multiply the first equation by 7:
21n+7r=182
Subtract the second equation from the first:
19n=133
Divide both sides by 19 to isolate n:
n=7
Plug this back in to find the value of a box of paper:
3(7)+r=26
21+r=26
r=5
Hope this helps!
Answer:
required time is here 45 minutes
Step-by-step explanation:
given data
apples = 100
bananas = 100
oranges = 100
pears = 100
solution
we have here 4 different kind of fruit
so that it is possible for each kind of fruit is
each kind of fruit is = 4 × 11 = 44
so each kind contain 11 fruit
as that 45th fruit make a dozen
now 1 fruit is pick every minute
'so we take here 45 minute to pick up 45 fruit
so that required time is here 45 minutes
Answer:A line segment
Step-by-step explanation:
Answer:
806.12 m
Step-by-step explanation:
<u>Step 1: Write the data</u>
<em>Side (s) = 12</em>
<em>Altitude (h) = 6</em>
<u>Step 2: Write the formula for surface area of right hexagonal pyramid</u>
<em>Area = 3√3/2*s² + 3*s*√(h²+3s²/4)</em>
<u>Step 3: Substitute values of 's' and 'h'</u>
<em>Area = 3√3/2*(12)² + 3*(12)*√[6²+3(12)²/4]</em>
Area = 806.12 m
Therefore, the total surface area of the pyramid is 806.12 m.
