Answer:

for a rectangle to be called a square with 4 sides must be equal

for rectangle to be called a square its four angles must be equal.

Answer:

all parallel sides are the same lengths

all angles are 90°

Step-by-step explanation:

We know that the square has the definition of an object or plane that has all the four sides of equal length,

And all the angles related to the sides are also same. (all angles are 90°)

Whereas, a rectangle gets defined as the plane figure with four straight sides and the same number of right angles where the two parallel sides become of equal length.

Step-by-step explanation:

just multiply 7.6g times 10

Step-by-step explanation:

step one:

The question is incomplete it did not specify weather the scale was a reduction or an increase in the dimension of the rectangle.

step two:

let us assume it was to be an increase i.e 7x

the length would be 4*7= 28 inches

the width would be 6*7= 42 inches

step three:

Also, we assume it was to a decrease i.e 7x

the length would be 4/7= 0.57 inches

the width would be 6/7= 0.85 inches

Answer:

[tex]z = \frac{8}{5}[/tex]

Step-by-step explanation:

Calculate for the value of [tex]z[/tex] :

[tex]2(4z - 1) = 3(z + 2)[/tex]

-Use Distributive Property on both left and right:

[tex]2(4z - 1) = 3(z + 2)[/tex]

[tex]8z - 2 = 3z + 6[/tex]

-Take [tex]3z[/tex] and subtract [tex]8z[/tex] :

[tex]8z - 3z - 2 = 3z - 3z + 6[/tex]

[tex]5z - 2 = 6[/tex]

-Add [tex]2[/tex] to both sides:

[tex]5z - 2 + 2 = 6 + 2[/tex]

[tex]5z = 8[/tex]

-Take [tex]5z[/tex] and divide on both sides:

[tex]\frac{5z}{5} = \frac{8}{5}[/tex]

[tex]z = \frac{8}{5}[/tex]

Therefore, the value of [tex]z[/tex] is [tex]\frac{8}{5}[/tex].

The solution to the given equation is [tex]z = \frac{8}{5} \ or \ 1\frac{3}{5}[/tex]

The given equation is 2( 4z - 1) = 3(z+2).

To solve the given equation means we should determine the value of the variable z.

To solve this, we will first clear the brackets

[tex]2(4z - 1) = 3(z+2)[/tex]

Clearing the brackets

[tex]8z - 2 = 3z + 6[/tex]

Now, collect like terms

[tex]8z - 3z = 6 + 2[/tex]

Then,

[tex]5z = 8[/tex]

Now divide both sides by 5

[tex]\frac{5z}{5} = \frac{8}{5}[/tex]

∴ [tex]z = \frac{8}{5} \ or \ 1\frac{3}{5}[/tex]

Hence, the solution to the given equation is [tex]z = \frac{8}{5} \ or \ 1\frac{3}{5}[/tex]

Answer:

[tex]Total\ Savings = 85 + 7 w[/tex] --- In w weeks

[tex]Total\ Savings = \$141[/tex] --- In 8 weeks

Step-by-step explanation:

Given

[tex]Available\ Amount = \$85[/tex]

[tex]Weekly\ Savings = \$7[/tex]

[tex]Number\ of\ weeks = 8[/tex]

Required

Determine the amount of savings in w weeks

This can be calculated as thus:

[tex]Total\ Savings = Available\ Amount + Weekly\ Savings * Number\ of\ weeks[/tex]

In this case;

w = Number of weeks

So, we have:

[tex]Total\ Savings = 85 + 7 * w[/tex]

[tex]Total\ Savings = 85 + 7 w[/tex]

When w = 8, we have

[tex]Total\ Savings = 85 + 7 * 8[/tex]

[tex]Total\ Savings = 85 + 56[/tex]

[tex]Total\ Savings = \$141[/tex]

The number of miles per year that he has rowed since he was given the machine will be Roughly 2000. Then the correct option is D.

Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.

The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.

A 63-year-old man has rowed around the world in his living room, according to a newspaper story. On a rowing machine that he received for his 50th birthday, he logged 24084 miles.

The number of miles per year is calculated as,

⇒ 24,084 / (63 - 50)

⇒ 24,084 / 13

⇒  1852.61 ≈ 2,000

The number of miles per year that he has rowed since he was given the machine will be Roughly 2000. Then the correct option is D.

Let, first integer is x.

Therefore, other two are x+1 , x+2 .

Now, mathematical expression of given conditions is :

4x + 3 = 3(x+2)

4x + 3 = 3x + 6

x = 3.

So, the consecutive numbers are 3 , 4 and 5.

Therefore, the middle integer is 4.

Hence, this is the required solution.

Given:

On a number line, suppose the coordinate of A is 0, and AR = 9.

To find:

The possible coordinates of the midpoint of AR.

Solution:

Coordinate of A is 0, and AR = 9.

It means the distance between point A and R is 9 units. It means, point R can be either left side or right side of A. So, location of point R can be either -9 or 9.

If coordinate of R is -9, then midpoint of AR is

[tex]\dfrac{0+(-9)}{2}=-4.5[/tex]

If coordinate of R is 9, then midpoint of AR is

[tex]\dfrac{0+(9)}{2}=4.5[/tex]

Therefore, the possible coordinates of the midpoint of AR are -4.5 and 4.5.
