85% of what number is 27.2

Answer: 9 - 6 = 3

Step-by-step explanation:

Answer:

7000

Step-by-step explanation:

This is because when you round to the significant figure, you basically look at any digits at the start of the number, which isn't zero. In this case, it would be in the thousands place 7284. So you round 7284 to the nearest thousands, which, would be 7000

Answer:

D

Step-by-step explanation:

given that

A(n)=-2•2^(n-1)

n->represent the terms

A(1)=-2•2^(1-1)=>-2•2^0

A(1)=-2•1=-2

For the fourth term

A(4)=-2•2^(4-1)

A(4)=-2•2^(3)

A(4)=-16

for the 8th term

A(8)=-2•2^(8-1)

A(8)=-2•2^(7)

A(8)=-256

Therefore first, fourth and eight => -2;-16;-256

Answer:

a: 7:3

b:by reading 10 hours

Answer:

a: 4 : 1

b: 12 (water) : 3 (sugar)

Step-by-step explanation:

ratio is similar to a fraction

water to sugar

the "to" is for what of every what it needs

to = can be used as ":"

For example:

For every 1 cup of sugar you need 4 cups of water to make the humming bird nectar. (it needs to be IN ORDER which is why for letter 'a' I did it water to sugar)

Step-by-step explanation:

Solution,

Effort=800N

Effort arm=80 cm

Load arm=20 cm

Load=?

Now,

by the principle of lever, we have

So, the load of 3200N can be lifted .

Answer:

load (l) =?

LOAD ARM = 20 CM

EFFORT ( E)= 800N

EFFORT ARM = 80cm

load *load arm = effort *effort arm

l*20 cm = 800 *80

L = 64000/20

answer = 3200

Step-by-step explanation:

Answer:

1500

Step-by-step explanation:

24 month means 2 years ( N )

rate 15 pcpa ( R )

amount is 5000 ( P )

so by formula

interest = P×N×R/100

so ( I ) = 5000×2×15/100

so( I ) = 50×2×15 ....... ( here 100 ( 2 zero ) and 5000.( 2 zero ) got canceled

so ( I ) = 50×2×15

so ( I ) = 100×15

so ( I ) = 1500

Part A

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

Explanation:

AP = arithmetic progression, which is another way of saying arithmetic sequence.

Let d = common difference

Apply substitution like so

x+d = 30

10+d+d = 30 ... replaced x with 10+d

10+2d = 30

2d = 30-10

2d = 20

d = 20/2

d = 10 is the common difference

Therefore,

x = 10+d = 10+10 = 20

The AP {10,x,30} updates to {10,20,30}. We see the gap between terms is 10 units. All AP's have the same gap width between adjacent terms.

=============================================================

Part B

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

Explanation:

We use the same ideas mentioned back in part A.

d = common difference = unknown for now

Hopefully you can see how each term builds up to form the next one. We'll solve that last equation like so

6+3d = 18

3d = 18-6

3d = 12

d = 12/3

d = 4

So we then can say:

The arithmetic sequence {6,x,y,18} updates to {6,10,14,18}. There's a gap of 4 between each adjacent term.

Answer:

1) 4900 is square

2) The greatest common factor 30 and 126 is 6.     The GCF of 126 and 39204 is 18

3) i) 44100 ii) 48024900

Answer:

Step-by-step explanation:

The y-intercept exists where the x coordinate is 0. Therefore, we can find it by plugging in a 0 for x and solving for y:

6(0) - 3y + 6 = 0 and

-3y + 6 = 0 and

-3y = -6 so

y = 2

Answer:

see explanation

Step-by-step explanation:

Given

6 - 4x - x²

Since the coefficient of the x² term < 0 then parabola has a maximum vertex.

To find the x- coordinate of the vertex

[tex]x_{vertex}[/tex] = - [tex]\frac{b}{2a}[/tex]

with a = - 1 and b = - 4 , then

[tex]x_{vertex}[/tex] = - [tex]\frac{-4}{-2}[/tex] = - 2

The corresponding y- coordinate is found by substituting x = - 2 , that is

6 - 4(- 2) - (- 2)² = 6 + 8 - 4 = 10

vertex = (- 2, 10 )

The maximum value of the function is the y- coordinate of the vertex

Then maximum value is 10

Thus 6 - 4x - x² is never greater than 10

Answer: I THINK fraction

Step-by-step explanation:

1/4 = fraction

To graph an exponential,

d. T-chart using random values for x and y.

The set of ordered pairings (x, y) where f(x) = y makes up the graph of a function.

These pairs are Cartesian coordinates of points in two-dimensional space and so constitute a subset of this plane in the general case when f(x) are real values.

Now,

We know an exponential function is a function in which the independent variable is the exponent.

One such function is y = eˣ

Now, To graph an exponential function you come up with values to use in the graph should be a T-chart using random values for x and y.

As it would result in graphing the complete nature of the function.

#SPJ7

Answer: London and Moscow.

Step-by-step explanation: This problem is simple. First, we use process-of-elimination. None of the positive values have a difference of 25 degrees, so one of the two values must be -12 degrees aka Moscow. From there, we add 25 to -12 to get 13. This means that the other city is London since it is 13 degrees.

Answer:

Step-by-step explanation:

1) 3 + 4*2*29 = 3 + 232  = 235  

First we have to do multiplication and then we have to add

2) 5n + 1

Term 1 ; n = 1  ;  5n + 1 = 5*1 + 1 = 5 + 1 = 6

Term 2 ; n = 2 ; 5n + 1 = 5*2 + 1 = 10 + 1 = 11

Term 3 ; n = 3 ; 5n+ 1 = 5*3 + 1 = 15 + 1 = 16

Term 4; n = 4  ; 5n + 1 = 5*4 + 1 = 20 + 1 = 21

Answer:

5^5

Step-by-step explanation:

5^3 * 25

Note that 25 = 5^2 (which is 5 * 5)

so we can rewrite the first expression as

5^3 * 5^2

We can add the exponents because we are multiplying and there is the same base (5):

5^(3+2) = 5^5

Step-by-step explanation:

number of shirts = x

price of shirts made = 9x+20

amount u earn by selling the shirts = 15x

profit = 15x - (9x+20)

profit of at least 150,  

15x - (9x+20) ≥ 150

Answer:

the right answer is 24

hope it help

Step-by-step explanation:

Solution:

Here,

Volume of the tank=539 litres

=539×1000cm^3=539000cm^3

Height=1.4×100cm=140cm

Let the radius of the base be r cm

Then,

22/7×r^2×140=539000

or,r^2=539000×7/22×140

or,r^2=1225

or,r=35 cm

So,

Area of base=pie r^2

=22/7×35^2

=3850 cm^2

Keep smiling and hope u r satisfied with my answer.Have a good day :)

Given Data:

Capacity of the Cylinder tank, V = 539 litres =

Height, h = 1.4 m

Area of the Cylinder, A = ?

Convert litres to m³: I litre = 0.001 m3

: . Capacity of the Cylinder tank = 539 litres = 0.539 m³

Let the radius of the base be r cm.

Find the radius of Cylinder:

Volume = πr²h

0.539 = πr²(1.4)

0.539 ÷ 1.4π = r²

r² = 0.12255

r = √0.12255

r = 0.35m

Find Area of Base:

Area, A = πr²

Area = π(0.35)² = 0.385 m²

Answer: The Area of base is 0.385 m²
