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

Step-by-step explanation:

If you use Desmos and enter (-3,-1) then enter your lines you can match them up.

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.

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

Step-by-step explanation:

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

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

There are 3 rectangles and 2 triangles in the prism

rectangles: (12 × 10) + (9 × 10) + (15 × 10)

triangles: 2 × (1/2 × 9 × 12) = 9 × 12

Add them all up and you get the answer of 468 in²

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.

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.
