Answer:

920 square feet

Step-by-step explanation:

Top: 20 * 17 = 340

Side triangles: 8 * 15 / 2 = 60

2 side triangles: 60 * 2 = 120

Back rectangle: 8 * 20 = 160

Bottom rectangle: 15 * 20 = 300

All of them: 340 + 120 + 160 + 300 = 920

The surface area is the sum of the area of the two similar triangles and the area of the three rectangles. Then the surface area of the geometry will be 920 square feet.

It deals with the size of geometry, region, and density of the different forms both 2D and 3D.

The surface area of the geometry will be

The surface area is the sum of the area of the two similar triangles and the area of the three rectangles.

The area of the rectangles will be

Area of rectangles = 8 x 20 + 15 x 20 + 17 x 20

Area of rectangles = 160 + 300 + 340

Area of rectangles = 800 square feet

The area of the triangles will be

Area of triangles = 2 x 1/2 x 15 x 8

Area of triangles = 120 square feet

Then the area of the geometry will be

Area of geometry = 800 + 120

Area of geometry = 920 square feet

Answer:

y=-4

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(-4-(-4))/(-6-4)=(-4+4)/-10=0/-10=0

slope is 0

y-y1=m(x-x1) where m=slope

y-(-4)=0(x-4)

y+4=0

y=0-4=-4

Step-by-step explanation:

Answer:

Angle <E is approximately 40 degrees, and angle <D is approximately 50 degrees

Step-by-step explanation:

Since angle <F is clearly 90 degrees, we can find angle E using the cosine function that relates the adjacent side to the angle with the hypotenuse:

[tex]cos(\theta)=\frac{adj}{hyp} \\cos(E)=\frac{6.5}{8.5}\\E = arccos(\frac{6.5}{8.5})\\E\approx 40.12^o[/tex]

And we use the sin function to deal with angle <D:

[tex]sin(\theta)=\frac{opp}{hyp} \\sin(D)=\frac{6.5}{8.5}\\D = arcsin(\frac{6.5}{8.5})\\D\approx 50^o[/tex]

Answer:

log(x^3*y^(-2))

Step-by-step explanation:

two log rules you need to know for this question:

alogb = log(a^b)

logx + logy = logxy

you can start by getting rid of the term in front of the log, or a

also is it 2 minus or 2 times negative? im assuming it's 2 times negative because it is more likely

log (x^3) + log (y^-2) = log (x^3*y^-2)

Answer:

64

Step-by-step explanation:

We have the function f(x) 7x^2 + 8x + 20 and are asked to solve it.

Since we know that x equals 2. We can substitute 2 for every x in the expression.

7(2)^2 + 8(2) + 20

First do the exponent :

2^2

4

7(4) + 8(2) + 20

Multiply 7(4) and 8(2) :

7(4)

28

8(2)

Answer:

$24.75

Step-by-step explanation:

4/5 of 13.75 = 11

11+13.75= 24.75

Dana  spends $24.75 in all.

An equation is a mathematical statement that equates two algebraic expression by an equal sign.

The data given in the question is

Dana spends $13.75 on a teacup for her grandmother

She spends 4/5 of that on a coffee mug for her grandfather.

The total amount  she spends is given by $x

The equation becomes

x = 13.75 + (4/5) * 13.75

x = $24.75

Therefore she spends $24.75 in all.

Answer:

26. H. (-4, -2)

27. A. x - 4

Step-by-step explanation:

26.

Use translations.

Start at point A(2, 6). To go from this point to the center of the circle, you must go from A(2, 6) to C(-1, 2). That means you need to go from 2 to -1 in x, a change of -3 in x, and from 6 to 2 in y, a change of -4 in y.

Since points A and B are the endpoints of a diameter, then AC and BC are radii of the circle. All radii are congruent, so if you apply the same transformation as from A to C to point C, you will get the coordinates of point B.

C(-1, 2) now is transformed by -3 in x and -4 in y.

B(-1 - 3, 2 - 4) ----> B(-4 , -2)

Answer: H. (-4, -2)

Recall the factoring of a difference of cubes.

a^3 - b^3 = (a - b)(a^2 + ab + b^2)

You have

x^3 - 64

x^3 is obviously the cube of x.

64 is the cube of 4, so you have

x^3 - 4^3

Following the factorization above, you get

(x - 4)(x^2 + 4x + 16)

Answer:

Sean is incorrect.

Step-by-step explanation:

The interior angle of this triangle with the exterior angle of 80° is 100°, so the sum of the remaining angles should be 80°, which means (X + 5) + (X - 5) = 80. Take off the parenthesis, 2X = 80, which means X = 40°. This is where Sean's answer was wrong, he forgot that the remaining angles are X + 5 and X - 5 instead of X, which means that the angles in this triangle should actually be 100°, 45°, and 35°.

Answer:

x = 60

Answer:

60

Step-by-step explanation:

[tex]\frac{1}{6}[/tex](x+6)=11

[tex]\frac{1}{6}[/tex]x + 1 = 11

[tex]\frac{1}{6}[/tex]x +1 -1 = 11 -1

[tex]\frac{1}{6}[/tex]x * 6 = 10 *6

x = 60

[tex]\frac{1}{6}[/tex](60+6)=11

10+1 = 11
