Amanda [17]

4400 - 3600 = 800

Decrease = 800 Calories
Original value was 4400 Calories.

Now,
$\frac{800}{4400} \times 100 \\ = \frac{2}{11} \times 100 \\ = \frac{200}{11} = 18.18 \: \%$

After Rounding off,
Decrease percentage will be 18 %

An integer is 3 less than 5 times together. If the product of the two integers is 36, then find the integers

saw5 [17]

Step-by-step explanation:

An integer is 3 less than 5 times another. If the product of the two integers is 36, then the integers are: 3 and 12. Solution: x * (5x 3) 36; 5x2 - 3x = 36; 5x2 -3x 36 = 0; (5x + 12)(x - 3) = 0; x = -12/5 or x =3.

Svetradugi [14.3K]

Answer:

50 de copii

Step-by-step explanation:

În această întrebare, fiecare dintre copii primește o carte pentru 32 de lei și o ciocolată pentru 8 lei.

Ceea ce înseamnă că suma totală primită de fiecare dintre copii va fi de 32 + 8 = 40 lei

Acum, din moment ce suma totală cheltuită este de 2000 de lei, numărul copiilor care se dau cărți și ciocolată va fi de

2000/40 = 50 de copii

Mary wants to hang a mirror in her room. The mirror and frame must have an area of 7 square feet. The mirror is 2 feet wide and

Umnica [9.8K]

Answer:

The quadratic equation used to determine the thickness of frame is $\left(3+2x\right)\times \left(2+2x\right)=7$

Step-by-step explanation:

Refer to the attachment for the diagram.

Consider EFGH as the the frame and ABCD as the mirror which is to be hanged.

Let me the "x" be the thickness of the frame as shown in diagram.

Given that, BC = 3 ft and DC = 2 ft which is the dimensions of the mirror.

Now to calculate the length and width of the frame consider following calculation,

Width of frame HG = x + DC + x

Width of frame HG = x + 2 + x

Width of frame HG = 2 + 2x

2x is the addition of the thickness which is present on both side of mirror

Length of frame FG = x + BC + x

Length of frame FG = x + 3 + x

Length of frame FG = 3 + 2x

Since it is an rectangular frame, so using the formula for area of rectangle

$Area\:of\:rectangle = length \times width$

Given that area of frame is $7\:ft^{2}$

Substituting the value,

$7 = \left(3+2x\right)\times \left(2+2x\right)$

Therefore, the quadratic equation used to determine the thickness of frame is $\left(3+2x\right)\times \left(2+2x\right)=7$
