Answer:

  (d)  2%

Step-by-step explanation:

The base of the exponent is the "growth factor". It is 1 more than the "growth rate", the fraction of change in 1 year.

 growth factor = 1 + growth rate

  1.02 = 1 + 0.02

  growth rate = 0.02 = 2%

The account increases 2% annually.

Answer:

√1 in the radical form and as (1)½

Step-by-step explanation:

Answer:

any root of 1 is 1

Step-by-step explanation:

*I am assuming that each equation only appears once instead of twice in this problem

6x-y=18

4x+2y=26

We are solving by elimination, and to do that, we need to make the coefficient of one of the variables the same for both equations. The easiest way would be to multiply the top equation by 2 which would result in

12x-2y=36

4x+2y=26

As we see now, -2 and +2 can cancel out if we add the two equations together. So B is correct.

The other solution to this problem is to get a common coefficient for x to do that we first find the least common multiple of 6 and 4 which is 12

so to get 12 we need to multiply equation 1 by 2 and equation 2 by 3

resulting in 12x-2y=36 and 12x+6y=78 which we can solve by subtraction

Although this second way works, we have to realize that this is not one of the solutions. Instead the solution proposed to multiply by 4 and 6 which actually is just what I did above but multiplying everything by 2 again.

In conclusion, the answers should be A and B

Answer:

13 guests, 72 ounces of dough, 58 ounces of sauce

Step-by-step explanation:

6 ounces of dough plus 4 ounces of sauce is 10 ounces so 130 divided by 10 is how you get your guests. Then multiply both 6 and 4 by 13 to get the ounces of both dough and sauce

Answer:

(i) 84 cm.

(ii) 5635π cm^2

Step-by-step explanation:

(i)

The volume of the cone = 1/3 π r^2 h

= 1/3 π 35^2 h.

The volume of the hemisphere = 2/3 π 35^3.

As the volume of the cone is 1 1/5 ( = 6/5) times the volume of the hemisphere:

1/3 π 35^2 h = 2/3 π 35^3 * 6/5

h = 2/3 π 35^3 * 6/5 / 1/3 π 35^2

h = 84 cm (answer).

(ii) Surface area of the hemisphere = 2 π * 35^2 = 2450π cm^2.

Surface area of the cone = π r l where l = slant height.

l = √(35^2 + 84^2) = 91 cm.

So the surface area of the cone = 35*91 π = 3185π.

So the total surface area of the solid is 3185π + 2450π

= 5635π cm^2.

i hope this work for you

The height and the base area of the cone are 6 units and 4π square units. Then the volume of the cone is 24π.

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

The height (h = 6) and the base area (b = 4π) of a cone is given.

Then the volume of the cone will be

Volume = b × h

Volume = 4π × 6

Volume = 24π

Answer:

1/12

Step-by-step explanation:

Chance of flipping heads: 1/2

Chance of rolling a two: 1/6

1/2 x 1/6 = 1/12

Answer:

1/2 x 1/6 = 1/12

probability of flipping head =1/2

rolling a two = 1/6

probability of flipping heads and rolling a two = 1/2 x 1/6

= 2 * (-4/5) + 6 * 1/3

= - 8/5 + 2

= - 8/5 + 10/5

= 2/5

Answer:i feel like its most likely gonna be the last one

Step-by-step explanation:

Answer:

On any quadrant you choose the points each will always be positive

Step-by-step explanation:

The absolute value of a negative number is positive  and the same goes for a positive number (the absolute value will always be positive) because it is how many numbers it is away from 0. For Example; the absolute value of -4 is +4 because it is 4 numbers away from 0. If |x|+|y| = |x+y| then an example would be |-4| + |3| = |-4+3| it would be 7 because the |-4| is 4 and the |3| is 3 giving you the sum of 7

Answer:

I think it is 192

Step-by-step explanation:

Volume of cube: 5 x 4 x 8 = 160

Area of diagonal: 160/2 = 80

Length of diagonal: 80 / 0.5 x 3 = 480

AB = 480 / 5 x 2 = 192

Answer:2764800

Step-by-step explanation:First step is to convert feet into inches:

1 foot = 12 inches

20feet = 20*12=240 inches

8feet = 8*12=96 inches

Now we can calculate total area:

A = height * width

A= 240 * 96

A=23040 inches²

We know the amount per one inch² and we need to find out total number of blades:

1 inch²                          120 blades

23040 inches²               x blades

Now we cross-multiply numbers:

1*x = 23040 * 120

x= 2764800

There are total of 2764800 blades in the entire law

Answer:

original coordinates A[-4,5], B[-3,1], C[-5,2

new coordinates [3,1], B[2,5] C[4,4]

Step-by-step explanation:

ok so the x is the horazontal line and the Y is the vertical line when your writing cooodinates you always write the X first then the Y. so to find the origanal corrdinates which i'm assuming are the coordinates for the blue triangle you have to find the first point so the one labled A, you look at the numbers on X so the horizontal line, and find out which number on that line has point A on it and you record that number this is the X then you look at the   numbers on the Y line, (the vertical line) and see which number has point A on it and record this number this is the Y do this for all the other points and you will have all of their coordinates.
