bearing in mind that the LCD in this case for those two denominators is 40, so let's use that for the sum

$\bf \cfrac{18}{20}+\cfrac{3}{8}\implies \stackrel{\textit{using the LCD of 40}}{\cfrac{(2)18+(5)3}{40}}\implies \cfrac{36+15}{40}\implies \cfrac{51}{40}\implies 1\frac{11}{40}$

Carlos wants to put 720 of his blocks in his toy box. A small set has 10 blocks and a large set has 100 blocks. How can you writ

Natasha_Volkova [10]

Carlos can put the blocks in this three ways:

(i) 32 large blocks and 4 small blocks.

(ii) 22 large blocks and 5 small blocks.

(iii) 12 large blocks and 6 small blocks.

The total quantity of blocks equals the number of blocks stored in the sets of blocks. Based on the information given, we derive the following algebraic expression:

$10\cdot m + 100\cdot n = 720$ , $\forall\,m,n\in \mathbb{N_{O}}$ (1)

Where:

$m$ - Quantity of small blocks.
$n$ - Quantity of large blocks.

Now we can clear $n$ in terms of $m$ :

$100\cdot n = 720 -10\cdot m$

$n = 7.2-0.1\cdot m$ (2)

From (2) we get the following combination of sets:

1) $m = 12, n= 6$

2) $m = 22, n = 5$

3) $m = 32, n = 4$

Carlos can put the blocks in this three ways:

(i) 32 large blocks and 4 small blocks.

(ii) 22 large blocks and 5 small blocks.

(iii) 12 large blocks and 6 small blocks.

When the space shuttle orbits 200 miles from the surface of the Earth, it is 4200 miles from the Earth's center. How far does th

VMariaS [17]

Answer: The shuttle travels 26,376 miles each time it circles the Earth.

Step-by-step explanation:

1. Use the formula for circumference.

$C=2(3.14)r$ , where $C$ represents the circumference and $r$ represents the radius.

2. Substitute the values into the formula.

$C=2(3.14)4200$

3. Solve the equation

$C=26376$

If the diagonals of a parallelogram from right angles,then the parallelogram is the rectangle

geniusboy [140]

The statement above is false.

If the diagonals of a parallelogram form right angles, then the parallelogram is a rhombus (a rhombus is a quadrilateral with four equal side lengths).

Note* = by saying the statement is false is not saying that the scenario presented in the statement cannot occur. If the rectangle was a square, then its diagonals can form right angles since a square is also a rhombus. However, if a rectangle was NOT a square, its diagonals would not form right angles. A true statement is a statement where ALL cases fit the said requirement(s).

The statement can also be corrected by saying:

If the diagonals of a parallelogram are congruent, then the parallelogram is a rectangle.

All rectangles (even a square) have congruent diagonals, so this statement would be true.

Hope this helps!
