Simplify the following expression by combining like terms.
3x + 2x - 5

Answer:

A = 226.08

Step-by-step explanation:

Assuming that you are  wrapping the sides of the cylinder and the circular top and bottom, then the formula for the surface area of the cylinder is:

A=2πrh+2πr^2 so substitute for each variable A=2(3.14)(3)(9) + 2(3.14)(3)^2

notice how I substituted 3 for the radius since it is 1/3 of 9 (the height)

Solving we get A = 169.56 + 56.52 = 226.08

Answer:

5/8

Step-by-step explanation:

3/4x5/6=15/24

15 and 24 can both divided by 3. so 15/3 is 5, 24/3 is 8.

And we can't simplify 5/8 anymore, so the answer is 5/8.

Answer:

y=-4

Step-by-step explanation:

(y+4)3-6y=2(4-2y)

(y)(3)+(4)(3)+-6y=(2)(4)+(2)(-2y)

3y+12+-6y=8+-4y

(3y-6y)+12=-4y+8

-3y+12=-4y+8

-3y+12+4y=-4y+8+4y

y+12=8

y+12-12=8-12

y=-4

Answer:

The volume of the hemisphere is approximately 231,623.3 m³

Step-by-step explanation:

The radius of the hemisphere in the question, r = 48 m

A hemisphere is obtained by sharing a sphere into two halves

The radius of the hemisphere = The radius of the sphere which describes it

∴ The volume of a hemisphere = The volume of a sphere ÷ 2

The volume of a sphere = (4/3)·π·r³

∴ The volume of a hemisphere = (4/3)·π·r³ ÷ 2 =  (2/3)·π·r³

∴ The volume of the given hemisphere with 48 m radius, V = (2/3) × π × 48³

∴ V = (2/3) × π × (48 m)³ = 231,623.343164 m³

When the measure of the volume of the hemisphere is rounded to the nearest tenth, we have, V ≈ 231,623.3 m³.

Step-by-step explanation:

The two triangles he drew and also the calculations he did are missing, so i have attached them.

Answer:

His calculations are not correct

Step-by-step explanation:

From the attached image showing the triangle, we can see that for the smaller triangle with w, 5.5 and 45° angle, it is clear that;

Opposite side is 5.5

Adjacent side is w

And angle is 45°.

Hypotenuse is unknown

Thus, from trigonometric ratios;

Opposite/adjacent = tan (angle)

Thus;

5.5/w = tan 45°

In Skylar's calculation, he expressed it as; 5.5/w = sin 45°

Therefore, his calculation is wrong.

Secondly, for the bigger triangle, it is clear that;

Opposite side is 5.5

Adjacent side is w + x

And angle is 35°.

Hypotenuse is unknown

Thus;

5.5/(w + x) = tan 35°

Whereas,skylar expressed his own as;

5.5/(w + x) = sin 35°

Again his calculation is wrong.

Answer:

x=2

Step-by-step explanation:

First, you want to distribute -2 into both terms in the parenthesis.

-2(x-3) = -2x+6

Now you have -2x+6=-3x+8

Next, I want to only have x on one side of the equation to solve it, so I will add 3x to both sides.

x+6=8

Finally, I subtract 6 from both sides so x is alone on one side of the equation

x=2

Now I know x = 2. To double check this, I can substitute 2 in for x in the original equation.

-2(2 - 3) = -3(2) + 8

-2(-1) = -6 +8

2 = 2

Both sides equal eachother, so x = 2 is the correct solution.

251.33in³

Step-by-step explanation:

Answer:

258.02 or 251.33in3

Step-by-step explanation:

I don't know which one for sure but go with the answer that most people got

Using the formulas

AB=s(s﹣a)(s﹣b)(s﹣c)

V=ABh

s=a+b+c

2

Solving for V

V=1

4h﹣a4+2(ab)2+2(ac)2﹣b4+2(bc)2﹣c4=1

4·12·﹣184+2·(18·18)2+2·(18·2)2﹣184+2·(18·2)2﹣24≈215.66641

or 216.

You measure Hight at the place where it makes a right angle (for these look at the dotted line and the number labeling it)

Answer:

1. 4 inches

2. 5 inches

3. 8 inches

Step-by-step explanation:

The heights are labelled.

Answer:

91.7 inches to 1 decimal place

Step-by-step explanation:

We will use Pythagoras's theorem to find the height of the pyramid.

The height of the Pyramid forms a right-angled triangle with half of the base and the slant height.

We can get half the length of the base by dividing the length of one side of the base = 20.4 by 2 = 10.2in

slant height = 92.3in

Therefore height = [tex]\sqrt{92.3^{2} -10.2^2} =91.73in[/tex]

The height of the pyramid is 91.73inches to 1 decimal place

Answer:

y > - (4/3) x - 3

Step-by-step explanation:

use (y2-y1)/(x2-x1) for slope, which is negative (use two points given, (-6, 5) and (3, -7))

y intercept is -3, but you can plug in values for x and y in any of two points given: (-6, 5) and (3, -7)

Then, dashed line indicates values along line are not included in inequality relationship

since shaded region is above line, the inequality uses ">"
