Answer:
56 packs
Step-by-step explanation:
1) (14*24 ) - packets of macaroni altogether.
2) repack into packs of 6.
(14*24)/6 = 56 packs
90
55+65=120
there are 3 numbers and when you divide them it makes 70.
70 x 3 = 210
210 - 120 = 90
55 + 65 + 90 = 210
210 / 3 = 70
Answer:
Step-by-step explanation:
When a circle is rolled out, the base becomes πr and the heignt of each cone becomes r, therefore when the circle is made the equation become πr²
Answer:
Step-by-step explanation:
(0, 1) (1, -1)
(-1 - 1)/(1 - 0) = -2/1 = -2
y - 1 = -2(x - 0)
y - 1 = -2x + 0
y = -2x + 1
Step-by-step explanation:
Hi there!
From above question;
A cuboid has a length of 25cm, a width of 5cm and height of (x-2)cm.
Length (l) = 25cm
width (b) = 5cm
height (h) = (x-2)cm.
a).
Volume= l*b*h
V = 25*5*(x-2)
V = 125(x-2)
V = 125x - 250 → Answer
b).
(i)
V = 750cm³
V = 125x - 250
750 = 125x - 250..........(i)
(ii)
The equation (i) is: 750 = 125x - 250
or, 125x = 750+250
or, 125x = 1000
or, X = 1000/125
Therefore, X= 8cm.
(iii)
Height (h) = x-2
= 8-2
= 6
Therefore, height is 6cm.
