Answer:

20.5 cm

21.5 cm

Step-by-step explanation:

Length is 21 cm correct to 2 significant figures

As per above definition:

Answer:

a.  L.B. = 20.5

b.  U.B. = 21.5

Step-by-step explanation:

Length is measured 21 cm correct to 2 significant figures

a.  Lower bound of 21

    =  20.5 < 21

    = 20.5

b. Upper bound of 21

     = 21 < 21.5

     = 21.5

Answer:

6*10^-3  >  5*10^-3

Step-by-step explanation:

[tex]6*10^{-3}\\6*\frac{1}{10^{3} }\\6*\frac{1}{1000}\\\frac{6}{1000}=\frac{3}{500}=0.006[/tex]

[tex]5*10^{-3}\\5*\frac{1}{10^{3} }\\5*\frac{1}{1000}\\\frac{5}{1000}=\frac{1}{200}=0.005[/tex]

0.006>0.005, therefore, 6*10^-3>5*10^-3

Answer:

Step-by-step explanation:

solution

We going to do this process in a stepwise manner

given the expression

18=6(2x – 8)

1. open bracket on the left-hand side (distributive property)

18=12x-48

2. collect like terms

18+48=12x

66=12x

3. divide both sides by 12 we have

x= 66/12

x= 33/6

x=11/2

Answer:

Mars is [tex]1.4 \times 10 ^{88} miles[/tex] farther from the sun than Earth?

Step-by-step explanation:

We can assume that the two planets are on a straight line. This would make the solution easier for us.

The average distance from Earth to the sun is about [tex]9.3 \times 10 ^{77} miles[/tex]

The average distance from Mars to the sun is about [tex]1.4\times 10^{88} miles[/tex]

To find how much farther is Mars from the sun than Earth, we simply need to subtract the distances between the Earth and the Sun and the Distance between Mars and the Sun.

This will be

[tex]1.4\times 10^{88} miles[/tex] - [tex]9.3 \times 10 ^{77} miles[/tex]  = [tex]1.4 \times 10 ^{88} miles[/tex]

Step-by-step explanation:

1 times 1 times 1 = 1

Answer:

9 pennies, 6 dimes, 12 quarters.

Step-by-step explanation:

Pennies = $0.01

Dimes = $0.10

Quarters = $0.25

Let x be the number of dimes. Then (x + 3) is the number of pennies and 2x is the number of quarters.

We have x($0.10) + (x + 3)($0.01) + 2x($0.25) = $3.69

x($0.10) + (x + 3)($0.01) + 2x($0.25) = $3.69

$0.1x + $0.01x + $0.03 + $0.5x = $3.69

$0.61x = $3.66

x = 6.

Therefore Bob has 9 pennies, 6 dimes and 12 quarters.

[tex] \boxed{ \bold{ \huge{ \boxed{ \sf{x = 0.875}}}}}[/tex]

Step-by-step explanation:

[tex] \sf{3[ x + 3(4x - 5)]  = 15x - 24}[/tex]

Distribute 3 through the parentheses

⇒[tex] \sf{3[ x + 12x - 15 ]  = 15x - 24}[/tex]

Collect like terms : 12x and x

⇒[tex] \sf{3[ 13x - 15 ]  = 15x - 24}[/tex]

Distribute 3 through the parentheses

⇒[tex] \sf{39x - 45 = 15x - 24}[/tex]

Move 15x to left hand side and change it's sign

Similarly, move 45 to right hand side and change it's sign

⇒[tex] \sf{39x - 15x = - 24 + 45}[/tex]

Collect like terms

⇒[tex] \sf{24x = - 24 + 45}[/tex]

Calculate

⇒[tex] \sf{24x = 21}[/tex]

Divide both sides of the equation by 24

⇒[tex] \sf{ \frac{24x}{24} = \frac{21}{24}} [/tex]

Calculate

⇒[tex] \sf{x = 0.875}[/tex]

Answer:

-2x(x^2+2x+3)

Step-by-step explanation:

-2x^3-4x^2-6x

You can only factor out the 2x the other part is not factorable.

The new dimensions of the garden are 8 feet and 7 feet.

A rectangle is a part of a quadrilateral, whose sides are parallel to each other and equal.

Given that,

The length of rectangular garden = 5 feet,

And the width of rectangular garden = 4 feet.

The area of rectangular garden = 5 x 4 = 10 square feet.

Let the length and width are increased by x feet, to make the new area 56 square feet.

The new length = 5 + x,

and new width = 4 + x.

The area = 56

(5 + x) × (4 + x) = 56

Substitute, x= 3 which satisfies the equation,

So, the new length of garden = 5 + 3 = 8 feet,

And the new width of garden = 4 + 3 = 7 feet.

Answer:

No matter where the center of rotation is located on the coordinate plane, each point in the preimage is the same distance from the point of rotation as its corresponding point in the rotated images. This distance is not affected by changing the location of P. Although this investigation covered vertices only, it's clear that any point on a shape or figure will be affected similarly.

  83

Step-by-step explanation:

If that number of skips is represented by s, we can write the proportion ...

  skips/seconds = s/15 = 332/60

  s = 332(15/60) = 332/4 = 83

She skipped at the rate of 83 skips in 15 seconds.

Step-by-step explanation:

We need to convert 25 cg : 4g in lowest terms.

We know that, 1 gram = 100 centigram

1 cg = (1/100) gram

25 cg = [tex]\dfrac{25}{100}[/tex] grams

To write 25 cg : 4g in lowest terms, the step to be done are as follows :

[tex]\dfrac{25\ cg}{4\ g}=\dfrac{\dfrac{25}{100}}{4}\\\\=\dfrac{\dfrac{25}{25\times 4}}{4}\\\\=\dfrac{1}{16}[/tex]

It means that the lowest term for 25 cg : 4g is [tex]\dfrac{1}{16}[/tex]

Answer:

(4) 0

Step-by-step explanation:

Given:

Looking at the angles measures, they form series of:

This is AP with the first term of 27 and common difference of 7

We can see one of the terms of this AP is 90

Since cos 90° = 0 ⇒ cos²90° = 0 and therefore given series equals to zero as one of the terms of multiplication is zero.

So correct answer choice is  Option 4) 0
