Answer:

The width should be more than 5 m. So it can be  6,7 ...

Step-by-step explanation:

The length of a flower garden is = 9 m

The width of a flower garden is   = w

The area of a flower garden > 45 sq. m

The area of a flower garden  = l * b

l * b > 45

9 * b > 45

the width should be more than 5 m. So it can be  6,7 ...

15.09

Step-by-step explanation:

By angle bisector property of a triangle, we have:

[tex] \frac{x}{17.1} = \frac{6}{6.8} \\ \\ x = \frac{17.1 \times 6}{6.8} \\ \\ x = \frac{102.6}{6.8} \\ \\ x = 15.0882353 \\ \\ x \approx15.09[/tex]

Answer:

7850 cm

Step-by-step explanation:

The formula for area of a circle is: [tex]\pi[/tex][tex]r^{2}[/tex]

[tex]50^{2}[/tex] = 2500

([tex]\pi[/tex] will be rounded to 3.14)

Step-by-step explanation:

The given equation is true for x=-5/3.

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

The given equation is 7x-2(x+1)+18 = 8x-11.

The solution of an equation is the set of all values that, when substituted for unknowns, make an equation true.

The solution for the equation 7x-2(x+1)+18 = 8x-11 is as follows

7x-2x-2+18 = 8x-11

⇒ 5x-16=8x-11

⇒ 8x-5x=-16+11

⇒ 3x=-5

⇒ x=-5/3

Verification:

Substitute x=-5/3 in the given equation and verify

That is, 5(-5/3)-16=8(-5/3)-11

⇒ -25/3 -16=-40/3 -11

⇒ (-25-48)/3 = (-40-33)/3

⇒ -73/3 =-73/3

LHS = RHS

Therefore, the given equation is true for x=-5/3.

A complex number is said to be additive if  the sum of a complex number and its additive inverse is zero. The additive inverse of the complex number is 2+ 8i

A complex number is said to be additive if  the sum of a complex number and its additive inverse is zero.

For instance the the additive inverse of the complex number a+bi is -a-bi.

Given the comlex number -2 + 8i, the additive inverse is expressed as:

Additive inverse = -(-2 - 8i)

Additive inverse = 2 + 8i

Hence the additive inverse of the complex number is 2+ 8i

The probability can be obtained using several methods :

Using a standard normal distribution table ;

P(Z < 0.37) = obtain the value at the intersection where 0.3 is on the vertical axis and 0.07 on the horizontal axis of the Z distribution table

Hence,

Answer:

x=y-44 and x+y=410

Step-by-step explanation:

So, you want to use the equations x=y-44 and  x+y=410 when x is Ann's score and y is Ruth's score. This is because x (Ann's score) is Ruth's score (y) but 44 less, so you subtract y-44 to get x. Then x+y would also have to equal 410 so that's the other equation. Graphing the 2 equations gets you to the point  (183,227) in which Ann's score is 183 points and Ruth's score is 227 points.

Step-by-step explanation: To divide mixed numbers, first rewrite the mixed numbers as improper fractions.

So here, 3/5 is already a fraction and 2 and 1/2 can be written as 5/2.

Remember that dividing by a fractions means the same thing

as multiplying by the reciprocal of that fraction.

In other words, 3/5 ÷ 5/2 can be rewritten as 3/5 · 2/5.

Finally, multiplying across the numerators and the

denominators, we have 6/25.

The result of the division of 3/5 divided by 2 1/2 is: 6/25.

Here, we have,
