Step-by-step explanation:
Volume= [(20+20) x (20+20) x 100] - (20 x 20 x 100)
=120000cm^3
surface area= 2 x 40 x 100 + 2 x (40 x 40 - 20 x 20) + 4 x 20 x 100
=18400cm^2
Answer:
d=104
Dasha's garden had 104 originally
Step-by-step explanation:
let d for dasha and a for Anna
d=4a
a=d/4
d-39=a+39
d-39=d/4 +39
d-d/4=39+39
3/4 d =78
3d=4*78
d=(4*78)/3
d=312/3
d=104
Dasha's garden had 104 originally
Answer:
a. 7(2g + 20t –3)
b. 14g + 140t – 21
Step-by-step explanation:
a. The first expression 7(2g + 20t – 3)
Stacey and her six friends implies that we have 7 members in the group.
Therefore, the expression above implies that each member of the group has to pay for two rounds of golf and 20 tokens will be discounted $3.00.
The expression (2g + 20t –3) represents the quantity of cost of each friend and this is multiplied by 7 to obtain this first expression, i.e. 7(2g + 20t –3).
b. The second expression 14g + 140t – 21
The simple interpretation of this expression us that deducting $21 from the to total bill which is 14 games of golf plus 140 tokens is equal to the total amount this group spent.
Therefore, this second expression is obtained by simply opening the bracket in the first expression by multiplying 7 by each of the what is in the bracket.
12mi / (3/4) hours = 1mi / ? Hours. Set up this proportion and cros multiply to find ?

- Whether the point ( 1 , 5 ) , a solution to the equation y = 2x + 3 or not.
Assuming the the value of x and y as 1 and 5 respectively. Now , plug the values of x and y in the given equation & let's see whether the point ( 1 ,5 ) , solution to the equation y = 2x + 3 or not !
⟶ 
⟶ 
⟶ 
Since we got 5 on R.H.S & L.H.S, So yeah! The point ( 1 , 5 ) is a solution to the equation y = 2x + 3.
Hope I helped ! ♡
Have a wonderful day / night ! ツ
