the equation A=6s to the power of 2 can be used to calculate A the surface area of the cube with edges lengths using this equation what is the surface area of a cube with an edge length of 5 inches?
Answer:
150 in^2
Step-by-step explanation:
The surface area, in general, is A = 6s^2, where s is the length of one side of the cube.
If the edge length is 5 in, then the surface area of the cube is
A = 6(5 in)^2 = 6(25 in^2) = 150 in^2
Leah flips a coin, and then she spins a spinner with 3 equal sections colored red, green, and blue. What is the probability that
the coin flips heads, and
the spinner lands on either red or blue?
Enter your answer as a percentage, to the nearest percent.
Answer:
1/3 ! i think?
Step-by-step explanation:
there's a 1/2 chance it lands on heads and a 2/3 chance it lands on red or blue and 1/2 x 2/3 is 1/3
The probability that the coin flips heads, and the spinner lands on either red or blue is 1 by 3.
Calculation of the probability:Since Leah flips a coin, and then she spins a spinner with 3 equal sections colored red, green, and blue.
Since there is half chance for heads and 2 by 3 for landing on red or blue
So, the probability should be
[tex]= 1/2 \times 2/3 \\\\= 1/3[/tex]
Hence, The probability that the coin flips heads, and the spinner lands on either red or blue is 1 by 3.

A triangle has a perimeter of 280 cm, and its side lengths are a, b and c respectively. If
a:b= 2:3, b:c=4:5, find the length of each side of the triangle.
Answer:
The length of the sides are 64 cm, 96 cm and 120 cm.
Step-by-step explanation:
Perimeter of a triangle:
The perimeter of a triangle is the sum of it's sides.
A triangle has a perimeter of 280 cm, and its side lengths are a, b and c respectively.
This means that:
[tex]a + b + c = 280[/tex]
a:b= 2:3
This means that:
[tex]\frac{a}{b} = \frac{2}{3}[/tex]
[tex]2b = 3a[/tex]
[tex]b = \frac{3a}{2}[/tex]
b:c=4:5
This means that:
[tex]\frac{b}{c} = \frac{4}{5}[/tex]
[tex]4c = 5b[/tex]
[tex]c = \frac{5b}{4}[/tex]
[tex]c = \frac{5*3*a}{4*2} = \frac{15a}{8}[/tex]
At the original equation:
We replace b and c in function of a. So
[tex]a + b + c = 280[/tex]
[tex]a + \frac{3a}{2} + \frac{15a}{8} = 280[/tex]
Multiplying everything by 8
[tex]8a + 12a + 15a = 280*8[/tex]
[tex]35a = 280*8[/tex]
[tex]a = \frac{280*8}{35}[/tex]
[tex]a = 64[/tex]
Sides b and c:
Since we have a, we can find sides b and c:
[tex]b = \frac{3a}{2} = \frac{3*64}{2} = 3*32 = 96[/tex]
[tex]c = \frac{15a}{8} = \frac{15*64}{8} = 15*8 = 120[/tex]
The length of the sides are 64 cm, 96 cm and 120 cm.

A tablet computer listed at an original price of $250 is placed on sale for
20% off the original price. Bob, an employee of the store, gets an
additional 30% off the sale price. What price would Bob pay to purchase
the tablet computer?
$100
$125
$200
$140
Answer:
$140
Step-by-step explanation:
250 decrease 20% =
250 × (1 - 20%) = 250 × (1 - 0.2) = 200
200 decrease 30% =
200 × (1 - 30%) = 200 × (1 - 0.3) = 140

Answer:
If the two polygons are similar, then their sides are proportianal.
We see that sides in the larger polygon are two times as long as the sides of the smaller polygon.
So, if the larger polygon has a side length of 13, then the smaller polygon would have a side length of 13/2, or 6.5

Why is a data point with an x-coordinate of 0 a good point to use when creating a trend line for a data set? The graph shows the altitude of a weather balloon over time. The trend line passes through the points (0,481) and (10,39,). Write the equation of a trend line for the data shown in the graph. After how many minutes is the balloon at an altitude of 454.6 feet above sea level?
It takes the balloon 0.6 minutes to reach an altitude of 454.6 feet above sea level
A linear equation is given by:
y =mx + b
where y, x are variables, m is the slope of the line and b is the y intercept.
Let y represent the altitude of the balloon at time x.
Given that a trend line passes through the point (0,481) and (10,39), the equation of the trend line is:
[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1} (x-x_1)\\\\y-481=\frac{39-481}{10-0}(x-0)\\\\y=-44.2x+481[/tex]
At 454.6 ft:
454.6 = -44.2x + 481
-26.4 = -44.2
t = 0.6 minutes
It takes the balloon 0.6 minutes to reach an altitude of 454.6 feet above sea level
