The length of the flag measure in meters is,

⇒ 1.52 meters

A measurement unit is a standard quality used to express a physical quantity. Also it refers to the comparison between the unknown quantity with the known quantity.

We have to given that;

A flag is 152 centimeters long.

Now,

We know that;

1 centimeters = 1/100 meters

Hence, We get;

The length of the flag measure in meters is,

⇒ 152 centimeters

⇒ 152/100 meters

⇒ 1.52 meters

Thus, The length of the flag measure in meters is,

⇒ 1.52 meters

Answer:

x = 2 + sqrt(2) or x = 2 - sqrt(2) thus B. is your answer

Step-by-step explanation:

Solve for x over the real numbers:

4 x^2 - 16 x + 8 = 0

Hint: | Write the quadratic equation in standard form.

Divide both sides by 4:

x^2 - 4 x + 2 = 0

Hint: | Solve the quadratic equation by completing the square.

Subtract 2 from both sides:

x^2 - 4 x = -2

Hint: | Take one half of the coefficient of x and square it, then add it to both sides.

Add 4 to both sides:

x^2 - 4 x + 4 = 2

Hint: | Factor the left-hand side.

Write the left-hand side as a square:

(x - 2)^2 = 2

Hint: | Eliminate the exponent on the left-hand side.

Take the square root of both sides:

x - 2 = sqrt(2) or x - 2 = -sqrt(2)

Hint: | Look at the first equation: Solve for x.

Add 2 to both sides:

x = 2 + sqrt(2) or x - 2 = -sqrt(2)

Hint: | Look at the second equation: Solve for x.

Add 2 to both sides:

Answer: x = 2 + sqrt(2) or x = 2 - sqrt(2)

Answer:

B

Step-by-step explanation:

x+14 = 7x+32-3x

x+14 = 4x+32

-x          -x

14 = 3x+32

-32       -32

-18 = 3x

/3        /3

-6 = x

x = -6

Answer:

x=-6

Step-by-step explanation:

x+14=7x+32-3x

x+14=7x-3x+32 group like terms

x+14=4x+32 add similar element

x+14-14=4x+32-14 subtract 14 from both sides

x=4x+18 simplify

x-4x=4x+18-4x subtract 4 from both sides

-3x=18

then divide both sides by 3

and then simplify

then u get x=-6

Answer:

1/3 -- 33.3%

37/100 -- 0.37

1/4 -- 25%

19/50 -- 30%

3/20 -- 15%

Step-by-step explanation:

Responda:

15cm

Explicação passo a passo:

Volume de uma pirâmide = Área da Base × Altura / 3

Dado

Volume = 2100m³

Altura da pirâmide = 30m

Vamos obter a área base primeiro, substituindo o valor dado na fórmula.

2100 = B (30) / 3

2100 = 30B / 3

2100 = 10B

10B = 2100

Divida os dois lados por 10

10B / 10 = 2100/10

B = 210cm²

Como a base é um quadrado

área da base quadrada = 210cm²

L² = 210

L = √210

L = 14,49cm

C ≈ 15cm

Portanto, a medida da borda de sua menor base é de aproximadamente 15 cm

Answer:

Percent · Base = Amount.

Step-by-step explanation:

Use n for the unknown (percent).

Divide to undo the multiplication of n times 72.

Move the decimal point two places to the right to write the decimal as a percent.

Answer:

Rachel will need 49 meters of fencing.

Step-by-step explanation:

From Geometry we know that area of the square ([tex]A[/tex]), measured in square meters, is represented by the following formula:

[tex]A = l^{2}[/tex] (Eq. 1)

Where [tex]l[/tex] is the side length of the square, measured in meters.

The length of the square is now cleared:

[tex]l = \sqrt{A}[/tex]

If we know that [tex]A = 150\,m^{2}[/tex], then the side length is:

[tex]l =\sqrt{150\,m^{2}}[/tex]

[tex]l \approx 12.247\,m[/tex]

The total amount of fencing is equal to the perimeter of the square ([tex]p[/tex]), measured in meters, that is:

[tex]p = 4\cdot l[/tex] (Eq. 2)

If we know that [tex]l = 12.247\,m[/tex], then the perimeter of the square is:

[tex]p = 4\cdot (12.247\,m)[/tex]

[tex]p = 48.988\,m[/tex]

As fencing is cut into 1-m lengths, we need to round this number up to the nearest integer. That is:

[tex]p = 49\,m[/tex]

Rachel will need 49 meters of fencing.

Answer:

21.186%

Step-by-step explanation:

z = (x-μ)/σ,

where

x is the raw score = 2400mg

μ is the population mean = 2000mg

σ is the population standard deviation = 500mg

z = 2400 - 2000/500

z = 0.8

Probability value from Z-Table:

P(x<2400) = 0.78814

P(x>2400) = 1 - P(x<2400) = 0.21186

Converting to percentage:

0.21186 × 100

= 21.186%

Therefore, the percent of the meals

ordered that exceeded the recommended daily allowance of 2400 mg of sodium is 21.186%

21.186% of the meals ordered exceeded the recommended daily allowance of 2400 mg of sodium.

It is known that 3000 meals ordered from Chipotle restaurants using the online site Grubhub.

And the distribution of sodium content is approximately Normal with mean 2000mg and standard deviation 500 mg.

We know,

[tex]z = \frac{(x- \mu)}{\(\sigma\)}[/tex],

And daily allowance of 2400 mg of sodium

x is the raw score = 2400mg

μ is the population mean = 2000mg

σ is the population standard deviation = 500mg

[tex]z = \frac{2400 - 2000}{500}[/tex]

z = 0.8

Probability value from Z-Table:

[tex]P(x<2400) = 0.78814\\P(x>2400) = 1 - P(x<2400) \\= 0.21186[/tex]

Converting to percentage:

[tex]= 0.21186 (100)\\= 21.186%[/tex]

Therefore, the percent of the meals  ordered that exceeded the recommended daily allowance of 2400 mg of sodium is 21.186%.

Step-by-step explanation:

the exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

121.8° is an exterior angle of the lower triangle , then

∠ 2 + 17.3° = 121.8° ( subtract 17.3° from both sides )

∠ 2 = 104.5°

------------------------------------

∠ 2 is an exterior angle of the upper triangle , then

∠ 1 + 37.1° = 104.5° ( subtract 37.1° from both sides )

∠ 1 = 67.4°

Answer:

36 inches

Step-by-step explanation:

Q = length of the sqaure

T = length of the triangle

Equation 1:  4Q = 3T  

Equation 2:    T = 3+Q;

Then, subsitute T=3+Q into equation 1:

4Q =  3(3+Q)

4Q = 9 + 3Q

Q = 9

-----

Each side of the square is 9 inches, so the perimeter will be 9X4 = 36inches
