Answer:
141.12 cm^2
Step-by-step explanation:
Since the area of a trapezoid is the average of the bases multiplied by the height, we can just plug these numbers into the equation! Since the average of 10.2 and 12.2 is 11.2, and the height is 12.6, we multiply them to get the area to be 141.12 cm^2.
Answer:
If you expand that, it comes out to 200000000, or in scientific notation, 2.0 × 10⁸.
Step-by-step explanation:
Starting with:
(7 × 10⁵) × (3 × 10²)
Since everything is multiplied, we can drop the brackets:
= 7 × 10⁵ × 3 × 10²
Now we can multiply seven by three, and both powers of ten:
= 20 × 10⁷
We can expand this now as
200000000
or in proper scientific notation:
2.0 × 10⁸
Answer: 32 divided by 4 = 8
Step-by-step explanation:
If the diagram is 8 ovals with 4 squares each, and we know that this is a division, then we have that an unknown number X is such that:
X/4 = 8
this is because we know that the division is by 4 (the number of squares in each oval) and the solution of the division is the number of ovals.
Then we can solve the equation for X.
X/4 = 8
We multiply each side of the equality by 4
X = 4*8 = 32
Then the diagram represents the division:
32/4 = 8 or " 32 divided by 4 = 8"
Set the equations equal to each other to find x
x - 2 = 3x + 4
-6 = 2x
x = -3
plug x into either equation
-3 - 2 = y
y = -5
(-3, -5)
the answer is B
A) The Girth is calculated as; 45.625 inches
B) The calculated girth is greater than the maximum of 45 inches and as such we will conclude that we will not be able to store the suitcase in the overhead compartment.
<h3>How to use basic math's operations?</h3>
We want to find the girth of a suitcase.
Now, we are told that the formula to calculate the girth of a suitcase is;
Girth = Length + Width + Depth
A) We are given;
Length of Suitcase = 24.5 inches
Width of suitcase = 14.25 inches
Depth of Suitcase = 6.875 inches
Thus;
Girth = 24.5 + 14.25 + 6.875
Girth = 45.625 inches
B) We are told that in order for us to use the suitcase in the overhead compartment, that the girth must not exceed 45 inches.
Now, our calculated girth is greater than the maximum of 45 inches and as such we will conclude that we will not be able to store the suitcase in the overhead compartment.
