4 3/16=(4·16+3)/16=67/16=4,1875 (pink ribbon)
5 1/16=(5·16+1)/16=81/16=5,0625 (green ribbon)
4,1875+5,0625=9,25 (total)
9,25·1,60=$14,8
<em>Answer: $14,8</em>
Answer:
Width = 7 cm
Length = 15 cm
Step-by-step explanation:
Let width = w
Length = w + 8
Area of rectangle = 105 sq. cm
length * breadth = 105
(w + 8)*w = 105
Use distributive property
w² + 8w = 105
w² + 8w - 105 = 0
Sum = 8
Product = -105
Factors = 15 , -7 {15 +(-7) = 8 & 15*(-7) = -105}
w² - 7m + 15m - 105 = 0
w(w - 7) + 15(m - 7) = 0
(w - 7)(w + 15) = 0
Ignore w + 15= 0 as measurements will not be in negative value
w - 7 = 0
w = 7
Width = 7 cm
Length = 7 + 8 = 15 cm
Density of any object of found by dividing its Mass by its Volume
So firstly we have to find the Volume
Volume of sphere =
where r is radius
So lets find the Volume
Volume of spherical marble =
=
Now mass = 10 grams
So density = Mass/Volume = rho
≈2.39 rho
Answer:
Therefore,
∴ x = 32 units
Step-by-step explanation:
Given:
Consider a Δ ABC with P and Q are the Mid points of AB and AC
AP = BP
AQ = CQ
PQ = 48
BC = 3x
To Find:
x = ?
Solution:
Mid Point Theorem :
The Midpoint Theorem states that the segment joining two sides of a triangle at the midpoints of those sides is parallel to the third side and is half the length of the third side.
i.e Here by Mid Point Theorem we will have
Substituting the values we get
∴ x = 32 units
Answer:
Step-by-step explanation:
4x where x = 5/7
=4 * 5/7
= 20/7
= 14/7 + 6/7
= 2 6/7
