Answer:

if you multiply by powers of 10 then make the decimal point go right.

Answer:

1.23 * 10^-7

Step-by-step explanation:

For decimals smaller than 1 usually something like 0.0000111 you count the decimal places backwards until you get to something greater than 0. So if you have 0.0022 the exponent would be 2.2 * 10^-3

For your problem 0.000000123

There's 6 zeros before you encounter the number thus your exponent is 1.23 * 10^-7

Here's a picture of how to do it!

Answer:

Step-by-step explanation:

6x10^8 = 600000000

1.5x10^-4 = 0.00015

600000000 divided by 0.00015 = 4e+32

4e+32 is the same as 4x10^-32

Answer:

the volume of the sphere is

[tex]33.51 in^{3}[/tex]

Step-by-step explanation:

This problem bothers on the mensuration of solid shapes, sphere and cube.

Given data

Volume of cube v =   64 cubic inches

since we are dealing with a cube the height and the radius of the sphere is same as the sides of the cube,

we know that volume of cube is expressed as

[tex]v= l*b*h[/tex]

[tex]v=l^{3}[/tex]

[tex]64= l^{3}[/tex]

[tex]l= \sqrt[3]{64}[/tex]

[tex]l= 4 in[/tex]

also diameter d=length l

Diameter d=  [tex]4in[/tex]

Radius r =  [tex]\frac{d}{2}[/tex]= [tex]\frac{4}{2}[/tex]= [tex]{2 in}[/tex]

Height h=[tex]4in[/tex]

we know that the volume of a sphere is given by

[tex]v= \frac{4}{3} \pi r^{3}[/tex]

substituting into the formula we have

[tex]v= \frac{4}{3} \ *3.142*2^{3} \\v=\frac{4*3.142*8}3} \\v= \frac{100.54}{3} \\v= 33.52in^{3}[/tex]

Answer:

14

Step-by-step explanation:

Graph all the points on a coordinate grid. Two sides are 4 units each and the other two sides are 3 unites each.

P = 2(l + w)

P = 2(3 + 4)

P = 6 + 8 ← (The distributive property) OR 2(7) ← (Normal way to solve)

P = 14 units and 14 units.

You could also do addition.

P = 3 + 3 + 4 + 4

P = 6 + 8

P = 14 units

Answer:

All of the choices.

Step-by-step explanation:

A rational number is one that can be represented by the ratio of two integers. In other words, if you can write the number as a fraction of two whole numbers, then it is a rational number.

All of these numbers can be written this way. Therefore, all of the numbers seen are rational.

Answer: 8 times.

Step-by-step explanation:

I will answer in English:

This says:

The volume of a cube is 125cm^3

How many times the volume will increase if we duplicate the lenght of the side?

If L is the lenght of the side, we have that the volume of the cube is:

V = L^3

If we duplicate the lenght of the side, the new volume is:

V = (2*L)^3 = 8*L^3

So we can see that the volume of the new cube is 8 times the volume of the previous cube.

Now,  we can do the math, for our original cube we have:

L^3 = 125cm^3

L = 5cm

the new cube has L' = 2*L = 10cm

The volume of this cube is:

V' = L'^3 = 10cm^3 = 1000cm^3

the ratio V'/V is:

1000cm^3/125cm^3 = 8

Answer: I agree with Sita.

Step-by-step explanation:

An infinite number is a very big number which is impossible to physically achieve. I agree with Sita because when Rita is forming equations on and on to an extent of not knowing when to stop. That is when she can say to infinite. And I don't think this is possible.

Answer:

Square

Answer A is correct

Answer:

A- square is the answer

Answer:

The length of one side of the blanket is [tex]8ft[/tex]

Step-by-step explanation:

In this problem we are expected to find the side of the square shape.

we know that the area of the square is expressed as

[tex]area= length * width[/tex]

but a square shape has all sides equal hence

[tex]area= length* length\\[/tex]

[tex]area= l^{2}[/tex]

substituting our area and squaring both side to find l we have

[tex]64= l^{2} \\l= \sqrt{64} \\l= 8 ft[/tex]

An improper fraction is one in which the numerator is bigger than the denominator, which means the value of the fraction is more than ' 1 ' .

Bob petered out after only 3/8 of an hour. This number is less than ' 1 ', so if it's left in the form of hours, it can't be an improper fraction.  If Bob wants his effort to look more impressive, he might try to describe his performance as 22.5 minutes. THAT number could be written as an improper fraction, (45/2 minutes), but somebody would be sure to notice his trick, and they would laugh at him.

Tina and Hadley both ran longer than 1 hour, so both of them could write their times directly as improper fractions, without any deceptive monkey business.

Tina . . . 3-4/9 hours . . . 31/9 hours

Hadley . . . 4-19/29 hours . . . 135/29 hours    

Answer:

The volume of the prism is 27 cubic inches.

Step-by-step explanation:

In order to calculate the volume of the given prism, we need to apply the correct formula. The volume of the wedge prism is given by the following formula:

[tex]Volume = \frac{1}{2}*b*h*l[/tex]

Applying the data from the problem on the equation above, we have:

[tex]Volume = \frac{1}{2}*6*4.5*2\\Volume = 6*4.5\\Volume = 27[/tex]

The volume of the prism is 27 cubic inches.

Answer:

A dress originally costs $120

Step-by-step explanation:

To find the original cost of the dress, we will follow the steps below;

let x represent the original cost of the dress

75% of x  = $90

[tex]\frac{75}{100}[/tex]  ×    x   = $90

[tex]\frac{75X}{100}[/tex]  =   $90

MULTIPLY both-side of the equation by 100

[tex]\frac{75X}{100}[/tex] × 100 =   $90×100

At the right-hand side of the equation, 100 will cancel out 100, leaving us with just 75x

75x = $9000

DIVIDE both-side of the equation by 75

75x/75 = $9000/75

At the left-hand side of the equation 75 will cancel-out 75 leaving us with just x

x=  $9000/75

x = $120

A dress originally costs $120

Answer:

Denote the two points are A and B, the balloon is C. Then we have,

Side AB = 9 miles

Angle CAB (angle A) = 27 deg

Ange CBA (angle B) = 45 deg

=> Angle ACB (angle C) = 180 - 27 - 45 = 108 deg

Applying the sine theorem:

AB/sinC = BC/sinA

=> BC = AB x sinA/sinC = 9 x sin27/sin108 = 4.3 miles

Denote CH as the height from C to side AB (or distance from ground to balloon), we have:

CH  = BC x sin B = 4.3 x sin*45 = ~3.04 miles

=> Distance from ground to balloon: ~3.04 miles

Hope this helps!

:)

Answer:

3.0 miles

Step-by-step explanation:

Let h be the height

Tan(27) = h/b

h = btan(27)

Tan(45) = h/(9-b)

(9-b)tan(45) = h

(9-b)tan(45) = btan(27)

9tan(45) = b[tan(45) + tan(27)]

b = 5.962138633

h = btan(27) = 3.037861367

Answer: 198 tickets

Step-by-step explanation: 1584/8 = 198

Answer:

90,747

Step-by-step explanation:

Clair delivery=79 per day

Total delivery per year=79×365 days

=28,835

Reagan delivery=2490 per month

Total delivery per year=2490×12 months

=29,880

Anthony delivery= 616 per week

Total delivery per year =616×52 weeks

=32,032

Total delivery altogether in a year=28,835+29,880+32,032

=90,747

Answer:

Step-by-step explanation:

Clair delivers 79 papers a day.

Assuming that there are 365 days in a year, it means that the number of newspapers that Clair delivers in a year is

79 × 365 = 28835

Reagan delivers 2490 papers a month. There are 12 months in a year. it means that the number of newspapers that Reagan delivers in a year is

12 × 2490 =29880

Anthony delivers 616 papers a week. Assuming that there are 52 weeks in a year, it means that the number of newspapers that Anthony delivers in a year is

52 × 616 = 32032

Therefore, the number of newspapers that they deliver altogether in a year is

28835 + 29880 + 32032 = 90747
