Answer:

x = 3

Step-by-step explanation:

[tex] {3}^{(x + 1)} + {3}^{x} = 108 \\ \\ {3}^{x} .3 + {3}^{x} = 108 \\ \\ {3}^{x} (3 + 1) = 108 \\ \\ {3}^{x} (4 )= 108 \\ \\ {3}^{x} = \frac{108}{4} \\ \\ {3}^{x} = 27 \\ \\ {3}^{x} = {3}^{3} \\ \\ \implies x = 3[/tex]

Answer:

x=5

Step-by-step explanation:

All we have to do for this equation is cross multiply. This means we multiply 7 and 5 together and 5 and x+2 together. This will make the equation 35=5(x+2). Simplify this to get 35=5x+10. Subtract 10 from both sides to get 5x=25. You want to isolate x so you have to divide both sides by 5. This will make the equation x=5.

Answer:

w = 4 and l = 9 or

l = 4 and w = 9

Step-by-step explanation:

let l = length

let w = width

2l + 2w = 26

lw = 36

l = 36/w

2(36/w) + 2w = 26

72/w + 2w = 26

(72 + 2w²) ÷ w = 26

cross-multiply:

2w² + 72 = 26w

2w² - 26w + 72 = 0

factor:

2(w² - 13w + 36) = 0

2(w - 4)(w - 9) = 0

w = 4 and l = 9 or vice versa

Answer:

x=48

Step-by-step explanation:

You start with the values of 4 and 16. Figure out how many times 4 goes into 16, which is 4. (4*4=16)

Now, since 4 is multiplied by itself to reach the value of 16, 12 will also be multiplied by 4 to give you the value of x.

Answer:

25 g

Step-by-step explanation:

0.1 kg can be written as 100 grams

& 75 g

while 1 kg is 1000 grams

so difference:-

(100- 75 ) grams

= 25 g

The difference between 0.1 kg and 75 g is 25 grams. To find the difference between 0.1 kg and 75g, you need to make sure both quantities have the same unit.

Since 1 kg is equal to 1000 g, you can convert 0.1 kg to grams:

0.1 kg = 0.1 * 1000 g = 100 g

Now, the two quantities are in the same unit:

0.1 kg - 75 g = 100 g - 75 g = 25 g

So, the difference between 0.1 kg and 75 g is 25 grams.

Answer:

160% of 35 is 56.

Step-by-step explanation:

[tex]\frac{56}{y} :\frac{160}{100}[/tex]

y · 160 = 56 · 100

160y = 5600

160y ÷ 160 = 5600 ÷ 160

y = 35

Answer:

830

Step-by-step explanation:

7470/9 = 830

Answer:

900% of 7470=67230

Step-by-step explanation:

To get the solution, we are looking for, we need to point out what we know.

1. We assume, that the number 7470 is 100% - because it's the output value of the task.

2. We assume, that x is the value we are looking for.

3. If 7470 is 100%, so we can write it down as 7470=100%.

4. We know, that x is 900% of the output value, so we can write it down as x=900%.

5. Now we have two simple equations:

1) 7470=100%

2) x=900%

where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:

7470/x=100%/900%

6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 900% of 7470

7470/x=100/900

(7470/x)*x=(100/900)*x       - we multiply both sides of the equation by x

7470=0.11111111111111*x       - we divide both sides of the equation by (0.11111111111111) to get x

7470/0.11111111111111=x

67230=x

x=67230

now we have:

900% of 7470=67230

Answer:

Cost of each eagle stamp = $0.25

Cost of each racoon stamp = $0.4

Step-by-step explanation:

Given:

Cost of 8 eagle stamp and 2 racoon stamp = $2.80

Cost of 3 eagle stamp and 4 racoon stamp = $2.35

Find:

Cost of each stamp

Computation:

Assume;

Cost of each eagle stamp = e

Cost of each racoon stamp = r

So,

8e + 2r = 2.80........... Eq 1

3e + 4r = 2.35 ........... Eq 2

Eq 1 x 2

16e + 4r = 5.6 .........Eq3

Eq 3 - Eq 2

13e = 3.25

e = 0.25

Cost of each eagle stamp = $0.25

8e + 2r = 2.80

8(0.25) + 2r = 2.80

2 + 2r = 2.80

r = 0.4

Cost of each racoon stamp = $0.4

The final answer is 27.889 (Feel free to round it)

Step-by-step explanation:

3.35 x 2.14 = 7.169

7.169 + 25 = 32.169

2 x 2.14 = 4.28

32.169 - 4.28 = 27.889

Answer:

True

Step-by-step explanation:

The Answer is 75.36 cm

2 x (pi)3.14 = 6.28

6.28 x (r)3 = 18.84

18.84 x (h)4 = 75.36

The statement, "If the radius of a cylinder is 3 centimeters and the height of the cylinder is 4 centimeters, then the area of the lateral surface is 75.36 square centimeters." is true.

"A cylinder is a three-dimensional geometrical structure which consists of two circular bases connected with a curved surface."

For a cylinder with radius r and height h,

the curved / lateral surface area is,

A = 2 × π × r × h

Given: r = 3 cm, h = 4 cm

Using the formula for area of lateral surface of a cylinder:

⇒ A = 2 × π × 3 × 4

⇒ A = 24 × π

⇒ A = 24 × 3.14

⇒ A = 75.36 sq.cm.

Therefore, given statement is true.
