I need help with number 4

Answer:

A. 2614 m^2 to the nearest square meter.

Step-by-step explanation:

Volume of the sphere

= 4/3 pi r^3 = 4000 pi

4/3 r^3 = 4000

r^3 = 4000 * 3/4 = 3000

r = ∛(3000)

The surface area

=4 pi r^2

= 4 * pi *  (∛(3000)^2

= 4 * pi * 208.008

= 2613.91 m^2.

The wrapping paper for this box cost (rounded to the nearest dollars and cents) should be $21.

Since

Wrapping paper costs $0.035 per square inch. And, there is a moving box that is an 10 inch cube is being wrapped.

So,

We know that

Surface area of the cube with side a is given by [tex]s = 6a^2[/tex]

[tex]= 6 \times 10^2 inch^2[/tex]

Now

So charge for 600 square inch should be like

[tex]= 600 \times $0.035[/tex]

= $21

hence, Wrapping paper for the box cost $ 21.00.

Answer:28oz-$4.89 is better deal. It is 17.5 cents per oz.

Step-by-step explanation:

Answer: The best option would be the 28 oz option

Step-by-step explanation:

First you would divide the dollar amount by the amount of ounces to get how much it is per ounce. For the 18 oz jar it is about 0.182 per ounce. For the 22 oz jar it is about .181 per ounce. For the 28 it is about 0.175 per ounce. Therefore the 28 oz is the best option.

Answer:

94.6m³

Step-by-step explanation:

The diagram shown in this question is a trapezoidal prism.

The volume of a trapezoidal prism is calculated as:

L × H × (P + Q/2)

Where L = Length = 4m

H = Height = 4.3m

P = Base width = 8m

Q = Top width = 3m

The volume of the trapezoidal prism =

4 × 4.3 ×(8+3/2)

=4 × 4.3 ×(11/2)

= 94.6m³

Therefore, the volume of the trapezoidal prism to the nearest tenth = 94.6m³

Answer:

60 feet cubed

Step-by-step explanation:

We are told type of pyramid is a rectangular pyramid.

The volume of a rectangular pyramid = 1/3 × Length × Width × Height

We are told that the pyramids have a base of 4 feet by 5 feet and a height of 4.5 feet.

Volume for one of the pyramid =

1/3 × 4 × 5 × 4.5

= 30 cubic feet

Since the pyramid has the same measurements, that means the second pyramid also has the volume of = 30 cubic feet.

The total volume of the figure of the two pyramids stacked together = 30 cubic feet + 30 cubic feet = 60 cubic feet or 60 feet cubed.

Answer:

Right Triangle

Step-by-step explanation:

BC is tangent to circle O, and since radius OB is perpendicular to this tangent, then the triangle must have a right angles in it, making it a right triangle.

The triangle could also be scalene, but that is not for sure, meaning it is primarily a right triangle.

Answer:

  90°

Step-by-step explanation:

The sum of the arcs around the circle is ...

  2x +4x +4x +2x = 360°

  x = 360°/12 = 30°

The numbered angle is the average of the measures of the intercepted arcs, so is ...

  (4x +2x)/2 = 3x = 3(30°) = 90°

The numbered angle is 90°.

6.75

Step-by-step explanation:

2+10+1+8+12+6+23+5+8+4+4+3+2.59+5.11+5.18+9.07 = 107.95

now we count how much numbers you added up which equals 16 and divide it with 107.95

107.95/16 = 6.746875

now you cant pay half a penny or such and such

Answer:

Let's call the length x. Since perimeter = 2 * (length + width) we can write:

6 = 2(x + 1/2)

3 = x + 1/2

x = 2 and 1/2

The answer is 2 and 1/2 miles long.

Answer:

2 miles

Step-by-step explanation:

Width, W = 1 mi.

Length = L

Perimeter, P = 6 mi.

2L + 2W = P:

2L + 2(1) = 6

2L + 2 = 6

2L = 6 - 2

2L = 4

L = 4 / 2

L = 2

Answer: 2 miles

Answer:

B. (8,1)

Step-by-step explanation:

x+y=9

x-y=7

x=7+y

Therefore in the equation x+y=9 , x=7+y

(7+y)+y=9

7+2y=9

2y=9-7

2y=2

y=2/2=1

therefore x=7+y

=7+1=8

The solution of the system of equation are,

⇒ (8, 1)

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

System of equations are,

x + y = 9  .. (i)

x - y = 7  .. (ii)

Now, We can simplify as;

From (i);

x = 9 - y

Put in (ii);

x - y = 7

9 - y - y = 7

9 - 2y = 7

9 - 7 = 2y

2y = 2

y = 1

From (i);

x = 9 - y

x = 9 - 1

x = 8

Thus, The solution of the system of equation are,

⇒ (8, 1)

Answer:

? = 54.

Step-by-step explanation:

According to the AA Theorem, the two triangles are similar.

[tex]\frac{35}{65} =\frac{63}{? + 63}[/tex]

[tex]\frac{7}{13} =\frac{63}{? + 63}[/tex]

7(? + 63) = 63 * 13

? + 63 = 9 * 13

? + 63 = 117

? = 54

Hope this helps!

The ratio of the corresponding sides will be constant. Then the missing segment will be 54.

A triangle is a three-sided polygon with three angles. The angles of the triangle add up to 180 degrees.

If the two triangles are similar, the ratio of the corresponding sides will be constant.

Let x be the missing segment.

x / 63 = 30 / 35

      x = 54

Hey there! :)

Answer:

A) (1, 6)

Step-by-step explanation:

Solve by setting both equations equal to each other. Begin by rearranging each equation to equal y:

3x + y = 9

y = -3x + 9

--------------

y - 2x = 4

y = 2x + 4

---------------

-3x + 9 = 2x + 4

Add 3x to both sides:

-3x + 3x + 9 = 2x + 3x + 4

9 = 5x + 4

Subtract 4 from both sides:

9 - 4 = 5x + 4 - 4

5 = 5x

Divide both sides by 5:

5/5 = 5x/5

x = 1. Substitute 1 into an equation to solve for y:

3(1) + y = 9

3 + y = 9

y = 9 - 3

y = 6.

Therefore, the coordinates of the solution are:

A) (1, 6)

Answer:

[tex]\boxed{OptionA}[/tex]

Step-by-step explanation:

3x+y = 9

y-2x = 4

Subtracting both equations

=> 3x+y-(y-2x) = 9-4

=> 3x+y-y+2x = 5

=> 3x+2x = 5

=> 5x = 5

Dividing both sides by 5

=> x = 1

Now, Putting x = 1 in the first equation

=> 3(1)+y = 9

=> 3+y = 9

=> y = 9-3

=> y = 6

Ordered pair = (x,y) = (1,6)

Answer:

y = -1/3x +5

Step-by-step explanation:

The slope intercept form is y = mx+b where m is the slope and b is the y intercept

The y intercept is 5  ( where it crosses the y axis)

The slope is

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

We need two points on the line ( 0,5) and (3,4)

m = (4-5)/(3-0)

   = -1/3

y = -1/3x +5

Start by finding the b or the y-intercept.

This is the point where the line crosses the y-axis.

Our y-intercept is (0,5) or just 6.

From here, we look for clear cut points on the line.

Notice that if we go down 1 unit and to the right 3 units,

our point will end up exactly in the middle of the cross.

So our slope is -1/3.

So the equation is -1/3x + 5.

4.9 seconds

Step-by-step explanation:

16.087 (t - 2.48648)^2 - 94.5842 = 0

solving as a quadratic equation yields t ≈ 4.9 seconds

Step-by-step explanation:

The displacement of a particle d (in km) as a function of time t (in hours) is given by :

[tex]d=2t^3+5t^2-3[/tex]

Displacement at t = 4 hours,

[tex]d(4)=2(4)^3+5(4)^2-3=205\ km[/tex]

Velocity of particle is given by :

[tex]v=\dfrac{dd}{dt}\\\\v=\dfrac{d(2t^3+5t^2-3)}{dt}\\\\v=6t^2+10t[/tex]

Velocity at t = 4 hours,

[tex]v=6(4)^2+10(4)=136\ km/h[/tex]

Acceleration of the particle is given by :

[tex]a=\dfrac{dv}{dt}\\\\a=\dfrac{d(6t^2+10t)}{dt}\\\\a=12t+10[/tex]

At t = 4 hours,

[tex]a=12(4)+10=58\ km/h^2[/tex]

Therefore, the displacement, velocity and acceleration at t = 4 hours is 205 km, 136 km/h and 58 km/h² respectively.

Answer:

25 units

Step-by-step explanation:

This problem can be solved by using concept of Basic proportionality theorem.

This theorem states that if there is line drawn parallel to any side of the triangle, and it intersect the other two sides, then

segment divided on those two sides are in equal proportion.

Let naem this triangle

the side containing 15 and 6 be AB, with A be point on segment having length 15 units

B be  point on segment having length 6 units

c be point on segment having length ? units

DE line parallel to BC

Thus, if apply Basic proportionality theorem. in this then ratio formed will be

15/6 = ?/10

5/2 = ?/10

?= 5/2* 10 = 25

The length of missing segment is 25 units.
