Answer:

C=2.75

Step-by-step explanation:

C/11=30/120

30/120=.25

120*.25=30

11*.25=2.75

Answer:

The value of x is 1

Step-by-step explanation:

Let us solve the question

∵ Δ PQR ≈ Δ FGH

→ From similarity, then their corresponding sides have an equal ratio

∴ [tex]\frac{PQ}{FG}[/tex] = [tex]\frac{QR}{GH}[/tex] = [tex]\frac{PR}{FH}[/tex]

∵ PQ = 3, QR = x + 3, PR = 2

∵ FG = 6, GH = 6x + 2, FH = 4

→ Substitute them in the ratios above

∴ [tex]\frac{3}{6}[/tex] = [tex]\frac{x+3}{6x+2}[/tex] = [tex]\frac{2}{4}[/tex]

→ By using cross multiplication between the first two ratios

∵ 3 × (6x + 2) = 6 × (x + 3)

∴ 3(6x + 2) = 6(x + 3)

∴ 3(6x) + 3(2) = 6(x) + 6(3)

∴ 18x + 6 = 6x + 18

→ Subtract 6x from both sides

∵ 18x - 6x + 6 = 6x - 6x + 18

∴ 12x + 6 = 18

→ Subtract 6 from both sides

∵ 12x + 6 - 6 = 18 - 6

∴ 12x = 12

→ Divide both sides by 12

∴ x = 1

Answer: 1.3 seconds

Step-by-step explanation:

Given: Distance of the moon to the Earth = 384,400 km = 384400 x 1000 meters = 384400000 meters.  [1 km = 1000 m]

Speed of light =[tex]2.998 \times 10^8[/tex]  m/s = 299800000 m/s

Formula: [tex]\text{Time}=\dfrac{\text{Distance}}{\text{Speed}}[/tex]

Let t be the time taken by the light to travel from the moon to the Earth.

[tex]t=\dfrac{384400000}{299800000}\approx1.3\text{ seconds}[/tex]

Hence, it will take approximately 1.3 seconds for the light to travel from the moon to the Earth.

The answer is:  

2c+1=6

Answer:

The expression Y = 8.09s + 3.79c  can be used to determine the total cost of the fabric.

Step-by-step explanation:

Given that:

Price per yard of satin fabric = $8.09

Yards of satin fabric bought = s

Price per yard of cotton fabric = $3.79

Yards of cotton fabric bought = c

Let,

Y be the total cost.

Y = 8.09s + 3.79c

Hence,

The expression Y = 8.09s + 3.79c  can be used to determine the total cost of the fabric.

Answer:

the answer is B  (2,1)

Step-by-step explanation:

Given the simultaneous equation

[tex]2x+3y=7 .....1\\x+y=3 ..........2\\[/tex]

Using substitution method

from equation 2 :

[tex]x=3-y ....3[/tex]

Substitute equation 3 into 1:

[tex]2(3-y)+3y=7[/tex]

Open the bracket

[tex]2(3)-2y+3y=7\\6-2y+3y=7\\6+y=7\\y=7-6\\y=1[/tex]

Substitute y=1 into x=3-y

[tex]x=3-1\\x=2[/tex]

Hence the solution to the equation is (2,1)

Answer:

7*(5)^0,5

Step-by-step explanation:

The value of number 7√5 in form of rational exponents will be 1561/1000.

A number which can be written in the form of fraction p / q , where q is non zero, are called Rational numbers.

Given that;

The number is,

⇒ 7√5

Now,

Since, The number is,

⇒ 7√5

Solve as;

⇒ 7√5 = 7 × 2.23

           = 15.61

           = 1561/100

Thus, The value in rational exponents = 1561/1000
