Answer:
1) I know that the sum will be negative because a negative number added to another negative number will still be a negative number.
2) First, I simplified -35 + (-61) to -35 - 61, which just equals -96.
-54 + 17 equals 54-17 = 37.
-96 < 37, so -35 + (-61) is less.
Step-by-step explanation:
The explanation is in the answer section, since your homework asked for me to explain.
Answer:
6 of each
Step-by-step explanation:
9+11=20
120 divided by 20 =6
9x6=54
11x6=66
54 + 66= 120
so six of each
Answer:
The base was 4 feet long.
Step-by-step explanation:
Hi there!
The area of the triangle is calculated using the following equation:
area = b · h / 2
Where:
b = base of the triangle.
h = height of the triangle.
We also know that the height is twice as long as the base, then:
h = 2 · b
With this information we can write a system of two equations with two unknowns:
16 ft² = b · h / 2
h = 2 · b
If we replace h by 2 · b in the first equation, we can solve the equation and obtain the value of the base:
16 ft² = b · (2 · b)/2
16 ft² = b²
√16ft² = √b²
4 ft = b
The base was 4 feet long.
Have a nice day!
The formula to find the volume of cube
cube = s^3
Therefore volume is equal to I^3
The second cube has 4x the First cube
4 × (I^3) = 4 ×I^3
Total volume of the second cube= 4I^3 cm3
Fact: the density(mass ÷ volume) of aluminium is 2.40g/cm3
Making mass the subject of the formula:
D = M ÷ V
(Times volume to remove deno minator)
Mass = Density × Volume
Mass = 2.40 × 4I ^3
Mass = 8.40I^3
By physics
weight= m × g
where
M = mass
g = acceleration due to gravity (= 9.8)
W = 8.40 I^3 × 9.8
Weight of aluminium = 82.32I^3
Answer:
Step-by-step explanation:
6w + 6 = 36
6w = 36 - 6
6w = 30
w = 30/6
w = 5
