Answer:

He can fit 11 ft^3

Step-by-step explanation:

Here, we want to get the volume it clothes that could fit into the two boxes

What we have to do here is to add the amount of space each of the box has to offer

Mathematically, we have this as;

7 ft^3 + 4 ft^3 = 11 ft^3

Answer:

lets use what we know.

given lengths are: 6, 3, 6, and 15.

We need to split the right triangle from the small little rectangle.

Now we add the lengths of the triangle to get the full length:

6 + 6 = 12

now we need to find the base:

15 - 3 = 12

Now we get our area of the triangle:

12 x 12 = 144

144 divided by 2 = 72

Now the small rectangle's area:

6 x 3 = 18

Add both of their areas to get:

72 + 18 = 90 ft2

Answer: Tu respuesta es 90² o la parte inferior.

Answer:

D) Neither the table nor the graph shows a proportional relationship

Step-by-step explanation:

We know the equation of the line:-

[tex]y-y_{1} =m(x-x_{1}) ~ m=slope[/tex]

[tex]m=\frac{y_{2}-y_{1} }{x_{2-} x_{1} }[/tex]

[tex](x_{1}y_{1})=(-1 ,-9)[/tex]

[tex](x_{2},y_{2} )=(1,-3)[/tex]

[tex]\frac{m=(-3)-(-9)}{1-(-1)} =\frac{-3+9}{1+1} =\frac{6}{2} =3[/tex]

[tex]m=3[/tex]

[tex]y-(-9)=3(x-1)[/tex]

[tex]y+9=3(x+1)[/tex]

[tex]y+9=3x+3[/tex]

[tex]y=3x-6 ~ or ~ y=3(x-2)[/tex]

so, your answer is D

Answer:

16.4 units

Step-by-step explanation:

Refer to the attached image, just find the hypotenuses of the three additional triangles, and add them up to become the perimeter of the yellow triangle.

Using Pythagoras Theorem:

Hypotenuse of the red triangle

[tex] = \sqrt{ {3}^{2} + {5}^{2} } [/tex]

[tex] = \sqrt{34} [/tex]

Hypotenuse of the blue triangle

[tex] = \sqrt{ {3}^{2} + {3}^{2} } [/tex]

[tex] = \sqrt{18} [/tex]

Hypotenuse of the green triangle

[tex] = \sqrt{ {2}^{2} + {6}^{2} } [/tex]

[tex] = \sqrt{40} [/tex]

The perimeter of the yellow triangle

[tex] = \sqrt{34} + \sqrt{18} + \sqrt{40} [/tex]

[tex] = 16.398...[/tex]

= 16.4 units

Hello! Sorry about your luck before although im 99% sure my answer is correct.

Answer: area is 180

Step-by-step explanation:

Ok so first starting off im going to calculate the area for each shape serperately and add them up since thats easier so as demonstrated in the picture the rectangle is 25 because i multiply by base × height and the base and height is 5 and 5 pointed in the picture so thats 25 although i didnt calculate the rest because the base and height is the same for each so we can just do 25 × 6 to get all the rectangles so 25 × 6 = 150 now we got the easy part out of the way now we should do the triangles I pointed to the base and height for that on the left the base being 5 and the height being 3 5 × 3 = 15 BUT WAIT this isn't are area for the triangles because when finding area for triangles we have to divide by 2 so... 15 ÷ 2 = 7.5 since there are 4 of those triangles I dont have to solve for the rest because i can just do 7.5 × 4 so...

7.5 × 4 = 30 now we just combine those areas together! so... 150 + 30 = 180 so 180 is our area HOPE THAT HELPS!

Givens

b1 = 12

b2 = 50

h = 21

Area = ?

Equation

Area = (b1 + b2) * h / 2

Solution

Area = (12 + 50) * 21 / 2

Area = 62 * 21 / 2

Area = 31 * 21

Area = 651

Answer:

x=1+√13 or x=1−√13

Step-by-step explanation:

Step 1: Subtract 39 from both sides.

5x2−10x−21−39=39−39

5x2−10x−60=0

For this equation: a=5, b=-10, c=-60

5x2+−10x+−60=0

Step 2: Use quadratic formula with a=5, b=-10, c=-60.

x=

−b±√b2−4ac

2a

x=

−(−10)±√(−10)2−4(5)(−60)

2(5)

x=

10±√1300

10

x=1+√13 or x=1−√13

Answer:

Step-by-step explanation:

Rewrite this quadratic in standard form by subtracting 39 from both sides.  We get:

5x^2 - 10x - 60 = 0

Reduce this by dividing all four terms by 5:

x^2 - 2x - 12 = 0

Use the quadratic equation to find the roots.  The coefficients of the x terms are 1, -2, -12. Thus the discriminant is b^2 - 4ac, or:

(-2)^2 - 4(1)(-12)  = -44   of which 4 is a perfect square factor and 11 is not.

Because the discriminant is negative, the given equation has two unequal, complex roots, which are:

      -(-10) ± i√4√11

x = -----------------------

                10

or x = 1 ± (1/5)√11
