How do I prove ABCD to be a rectangle

Answer:

21 rows and two Blocks

1 row 42 Blocks

Step-by-step explanation:

Number of blocks with Annabelle = 42

First arrangement = 3 rows 14 blocks

Second arrangement = 6 rows 7 blocks

Solution

The other two factor pairs that could be used to rearrange the blocks again?

Solution:

Here, we will have to find the factor pairs of total number of blocks present with Annabelle.

i.e. 42

First of all, let us have a look at the factor pairs of 42.

Therefore, the other two factor pairs can be 2, 21 and 1, 42.

The other two possible factor pairs are:

21 rows 2 blocks

1 row 42 blocks

352₈ = 3•8² + 5•8¹ + 2•8⁰

352₈ = 3•64 + 5•8 + 2•1

352₈ = 192 + 40 + 2

352₈ = 234

Answer:

£86.50

Step-by-step explanation:

To find how much 10 t-shirts cost we have to find how much they cost individually.

3 T- Shirts / 25.95 = 8.65 which means that each T-Shirt Costs 8.65.

8.65 x 10 T-Shirts = £86.50

If 2.383 is rounded to the nearest hundred the answer is 2.38

[tex]\huge\bold\blue{2.38}[/tex]

Explanation:

2 - ones

. - decimal point

3 - tenths

8 - hundredths

2 - thousandths

8 is the digit in the hundredths place

look at the number on its right (which is 2)

if: < 5, just copy the number until the nearest hundredths.

if: > or = 5, add 1 to the hundredths then copy the number until the nearest hundredths

Answer:

y=3x+1 or 3x-y=-1

Step-by-step explanation:

Hello,

We are given the line 3y+x=-2, and we want to write an equation of the line that is perpendicular to 3y+x=-2, and contains the point (-2, -5)

First, we'll need to find the slope of 3y+x=-2, as perpendicular lines have slopes that multiply to -1

In order to find the slope of 3y+x=-2, let's convert the equation of the line from standard form to slope-intercept form, which is y=mx+b, where m is the slope and b is the y intercept

y is isolated by itself in slope-intercept form, so let's subtract x from both sides of the equation

3y=-x-2

Now divide both sides by 3

y=[tex]-\frac{1}{3}x - \frac{2}{3}[/tex]

The slope of the line is -1/3

Now to find the slope of the line perpendicular to it, use this formula:

-1/3m=-1

Multiply both sides by -3

m=3

So the slope of the line perpendicular to it is 3

We can write the equation of this new line in slope-intercept form; substitute 3 as m in y=mx+b:

y=3x+b

Now we need to find b

As the equation passes through the point (-2, -5), we can use its values to help solve for b

Substitute -2 as x and -5 as y:

-5=3(-2)+b

Multiply

-5=-6+b

Add 6 to both sides

1=b

Substitute 1 as b:

y=3x+1

The equation can be left as this, or we can write it in standard form, if you wish

In standard form, x and y are on the same side; so we'll subtract 3x from both sides in order to have both variables on the same side

-3x+y=1

However, a (the coefficient in front of x) cannot be negative; so we'll multiply both sides by -1 to change the sign of the variable.

3x-y=-1

Hope this helps!

First, there are NO 5-digit pin codes that include the digits 7, 2, 4, 6, 9, and 3. But, there are 720 pin codes that include 5 out of the 6 digits.

Answer:

Width: 16

Length: 27

Step-by-step explanation:

Let x be the width of the rectangle.

The length would then be 2x - 5

The perimeter is:

2x - 5 + x + 2x - 5 + x =

6x - 10 = 86

Solve.

6x = 96

x = 16

Thus,

Width: 16

Length: 27

Answer: 50 * 100 = 5000

Step-by-step explanation:

a simple way of multiplying numbers that are a 1 with zeros is by simply moving the zeros from that number to the other number

100 has 2 zeros, so you ad them to the 50. 50 with 00 is 5000

Answer: 5O x IOO = 5OOO

Step-by-step explanation:

5OOO, think of it like 5 x 1, 5 x 1 = 5, now add 3 zero’s since there are 3 zeros.

Answer:

(-3/2, 6)

Step-by-step explanation:

(-3,8) (6,-4)

As we move along the line segment with endpoints (-3,8) and (6,-4) from  (-3,8) to (6,-4) x increases by 9 units (from -3 to 6) and y decreases by -12 units (from 8 to -4).

for ratio of 1:5

Since 1+5=6, the point we are looking for is 1/6 of the way from (-3,8) to (6,-4).  

So, the desired point is

(-3 + (1/6)(9), 8 - (1/6)(12) )

= (-3 + 3/2 , 8 - 2)

= ( (-6 + 3)/2, 6)

= (-3/2, 6)
