Answer:
480 cm ^ 2
Step-by-step explanation:
To calculate the surface area of the figure, we must calculate the surface area of the cube, we know that they are identical, therefore, calculating the area of one is sufficient.
We have that the surface area of a cube is:
A = 6 * a ^ 2
where a is the edge, we know that if it is a cube all its sides are equal, in this case it is 4 centimeters, if we replace we have:
A = 6 * (4 ^ 2)
A = 96
96 square centimeters is the area of a cube, but since the area of the object would be the sum of the area of all the cubes, then:
AT = 96 * 5
AT = 480 cm ^ 2
The surface area of the object formed with the cubes is 480 cm ^ 2
<span>Last week, Rosa ran 6 1/4 laps around the lake. Clara ran 1/5 as many laps around the lake as Rosa did. How many laps around the lake did Clara run?</span>
Answer:
has two terms without any negative exponent. so it is a polynomial.
Step-by-step explanation:
A polynomial is a expression with more than one terms.
The expression with negative exponent is not a polynomial.
Expression in the denominator is also not a polynomial
has two terms without any negative exponent. so it is a polynomial.
option B,C and D has negative exponents, so it is not a polynomial.
3y - 1 < 3
Isolate the y. Treat the less than or equal like an equal sign.
Do the opposite of PEMDAS. First, add 1 to both sides
3y - 1 (+1) < 3 (+1)
3y < 4
Next, divide 3 from both sides
3y/3 < 4/3
y < 4/3
y < 4/3 is your answer
hope this helps
Answer:
the answer is 45 because there are four marbles so it would be a 50/50
