The number of cubes form a pattern.
a) Draw an expression for the number of cubes in figure n.
b) How many cubes are there in the 50th figure?
c) What number has the figure consisting of 156 cubes​

.

[tex]f(100) = 498[/tex]

.

.

[tex]f(2) = 8[/tex]

[tex]f(3) = 13[/tex]

.

[tex]3b - 2b = 13 - 8[/tex]

[tex]b = 5[/tex]

.

[tex]f(1) = f(2) - b[/tex]

[tex]f(1) = 8 - 5[/tex]

[tex]f(1) = 3[/tex]

.

[tex]f (x)= f(1) + (x - 1)b[/tex]

[tex]f(100) = 3 + (100 - 1)5[/tex]

[tex]f(100) = 3 + (99)5[/tex]

[tex]f(100) = 3 + 495[/tex]

[tex]f(100) = 498[/tex]

Given

Once around park measures 420 yards

Todd needs to complete 5 miles

He runs 30 times during the week

We know, [tex]1\ mile=1760\ yards[/tex]

for 30 rounds, distance is

[tex]\Rightarrow 30\times 420=12,600\ \text{yards}[/tex]

In miles, it is

[tex]\Rightarrow 12,600\equiv \dfrac{12,600}{1760}\\\Rightarrow 7.159\approx 7.16\ \text{miles}[/tex]

As he runs more than the target. Therefore, he completed his target of 5 miles.

Step-by-step explanation:

I used a calculator.

9514 1404 393

Answer:

Step-by-step explanation:

AC and DE are diameters, so divide the circle into equal portions that have a total angle measure of 180°.

  angle ABD = 180° -angle DBF - angle FBC = 180° -75° -60°

  angle ABD = 45°

angle CBE is a vertical angle to angle ABD, so has the same measure, 45°.

angle ABE is supplementary to angle CBE, so has measure 180° -45° = 135°. Long arc AE is 360° less this value, so is 360° -135° = 225°. Vertical angle DBC has the same measure as angle ABE, so long arc DAE will also be 225°.

angles FBC and CDE add to make angle FBE, so that angle is ...

  angle FBE = 60° +45° = 105°

Answer:

[tex]50.04[/tex]

Step-by-step explanation:

Use this formula for arc length

[tex]2\pi \times r( \frac{x}{360} )[/tex]

where r is the radius and x is the arc measure.

We know Arc de is 8.73 so we are finding x.

R equal 10.

[tex]2\pi \times 10( \frac{x}{360} ) = 8.73[/tex]

[tex]20\pi( \frac{x}{360} ) = 8.73[/tex]

[tex]20\pi \times x = 3142.8[/tex]

[tex]x = \frac{3142.8}{20\pi} [/tex]

x=50.04

The value of the angle will be 50.04.

It is given in the question that

The arc of the circle A=8.73 In

The radius of the circle =10 In

Now from the formula of arc

[tex]A=2\pi r(\dfrac{\theta}{360} )[/tex]

[tex]8.73=2\pi 10\times \dfrac{\theta }{360}[/tex]

[tex]\theta = \dfrac{8.73\times 360 }{ 2\pi\times 10} =50.04[/tex]

[tex]\theta=50.04[/tex]

Thus the value of the angle will  be 50.04

Answer:

x = 30°

Step-by-step explanation:

< A = 90° {Being vertically opposite angles }

Now

x + 90° + 2x = 180° (Being linear pair)

3x = 180° - 90°

3x = 90°

x = 90° / 3

x = 30°

distribute and combine like terms

Answer:

(4, -2)

Step-by-step explanation:

7x+3y= 22

3x-3y= 18

Add them in vertical columns. 7x + 3x = 10x. The 3y and the -3y cancel each other out. 22+ 18 = 40.

You're left with 10x = 40. Solve for x by dividing both sides by 10

x = 4

Plug in 4 into any of the original equations and solve for y.

7(4) + 3y =22.

28 + 3y =22

Subtract 28 on both sides

You're let with 3y = -6. Solve for y by dividing both sides by 3

y= -2
