Alja [10]

Answer:

$x = 10$ will make the equation true

Step-by-step explanation:

Given

$\{3,10,90,108\}$

$3x +3= 33$

Required

Which is true for x

We have:

$3x +3= 33$

Collect like terms

$3x= 33 - 3$

$3x= 30$

Solve for x

$x = 30/3$

$x = 10$

Answer:

(a) 34 ft²

Step-by-step explanation:

The "top" and "back" together have a height of 2 ft + 1 1/2 ft = 3 1/2 ft. The bottom and front will have the same height, so the central vertical rectangle in the net will have a height of 2×(3 1/2 ft) = 7 ft. It is shown as having a width of 4 ft, so its area is ...

A = WH = (4 ft)(7 ft) = 28 ft²

__

The two areas labeled "left" and "right" are shown as having a height of 1 1/2 ft. Their width is the same as the width of the bottom (or top), so is 2 ft. The total area of the left and right sides is then ...

left + right = 2WH = 2(2 ft)(1 1/2 ft) = 6 ft²

That makes the area of the entire net be ...

total surface area = 28 ft² +6 ft² = 34 ft²

The surface area of the box is 34 square feet.

1. $18-4,25=13,75 \\ 13,75-9,75=4 \\ 0,50x \leq 4$ <u />⇔ $x= \frac{4}{0,50}$ ⇔ $x= 8$
R: She can buy 8 crackers

2. Amy used 13%
Dan used 0,14*100 = 14%
Mike used 0,5*100 = 50%

On a map, a distance of 2 cm represents 15 km. What is the distance (in km) between two cities that are 11 cm apart on the map?

GenaCL600 [577]

Answer:

82.5 km

Step-by-step explanation:

Given:

$\frac{2cm}{15km} =\frac{11cm}{?km}$

Cross-multiply.

2x = 11(15)

Divide both sides by 2 and solve for x.

x = 82.5 km

Genghis Khan organized his men into groups of 10 soldiers under a "leader of 10." Ten "leaders of 10" were under a "leader of 10

Drupady [299]

Answer:

(a) 11110 soldiers

(b) 6404 soldiers

Step-by-step explanation:

Following that logic you can express the men of any level of his organization as 10^n, where n is the level. Some examples:

Level 1: 10^1 = 10

Level 2: 10^2 = 100 Each of the 10 men in level 1 are in charge of 10 men in the level 2 (10 * 10 = 100)

(a) if the lowerst level of the organization has 10,000 soldiers, then the lowest level is:

10^n = 10,000

n = 4

The total number of men under him is:

10^4+10^3+10^2+10^1 = 11110 (Assuming that he is the leader of the first 10 leaders)

(b) In this case the lowest level has 5763, you have a 1 leader for every 10 soldiers, then the leaders needed for the lowest level is:

5763/ 10 = 576.3 = 577 leaders

These 577 leaders also have their own leaders for every 10:

577/10 = 57.7 = 58 leaders

And these also have their own leaders:

58 / 10 = 5.8 = 6

And again We assume these 6 are directly under Genghis Khan

Total soldiers:

5763 + 577 + 58 + 6 = 6404 soldiers
