Answer:
The base area is 3.24 dm^3
Step-by-step explanation:
Let the total volume of the cube be x l
3/4 of this is 4.374 l
Thus, we have it that;
3/4 * x = 4.374
3x = 4 * 4.374
x = (4 * 4.374)/3
x = 5.832 L
The volume of a cube is the length of its side raised to the power of 3
Let us have the length as y
so;
y^3 = 5.832
y = cube root of 5.832
y = 1.8 dm
The area of the base is simply the side length raised to the power of 2
we have this as:
1.8 * 1.8 = 3.24 dm^2
Answer:
three consecutive numbers that add up to 84 are 27,28 and 29
Step-by-step explanation:
27+28=55
55+29-=84
Answer:
Step-by-step explanation:
C = πd. An equivalent formula is C = 2πr.
Solving the first equation for π, we get π = C/d. Solving the second equation for r, we get π = C / (2r)
Answer:
The smallest possible perimeter of the triangle, rounded to the nearest tenth is 72.4 in
Step-by-step explanation:
The Triangle Inequality Theorem states that the sum of any 2 sides of a triangle must be greater than the measure of the third side
Let
x ------> the length of the remaining side
Applying the triangle inequality theorem
1) x+x > 30
2x > 30
x > 15 in
The perimeter is equal to
P=30+2x
<em>Verify each case</em>
1) For P=41.0 in
substitute in the formula of perimeter and solve for x
41.0=30+2x
2x=41.0-30
x=5.5 in
Is not a solution because the value of x must be greater than 15 inches
2) For P=51.2 in
substitute in the formula of perimeter and solve for x
51.2=30+2x
2x=51.2-30
x=10.6 in
Is not a solution because the value of x must be greater than 15 inches
3) For P=72.4 in
substitute in the formula of perimeter and solve for x
72.4=30+2x
2x=72.4-30
x=21.2 in
Could be a solution because the value of x is greater than 15 inches
4) For P=81.2 in
substitute in the formula of perimeter and solve for x
81.2=30+2x
2x=81.2-30
x=25.6 in
Could be a solution because the value of x is greater than 15 inches
therefore
The smallest possible perimeter of the triangle, rounded to the nearest tenth is 72.4 in
