Answer:

The man or woman that entered the room was 55 years of age.

Step-by-step explanation:

If we add up all the ages together, it is 95. When the other person walks in, the mean changes to 25. If you do the math, or if you count, the man or woman that enters is 55, which when added together, gives 150. divided by 6 equals 25.

Answer:

2 real solutions

Step-by-step explanation:

Remember this messy thing?

[tex]x=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}[/tex]

The quadratic formula, as it's called, gives us the roots to any quadratic equation in standard form (ax² + bx + c = 0). The information on the type of roots is contained entirely in that bit under the square root symbol (b² - 4ac), called the discriminant. If it's non-negative, we'll have real roots, if it's negative, we'll have complex roots.

For our equation, we have a discrimant of (-3)² - 4(6)(-4) = 9 + 96 = 105, which is non-negative, so we'll have real solutions, and since quadratics are degree 2, we'll have exactly 2 real solutions.

Answer:

H

Step-by-step explanation:

Answer:

40 units

Step-by-step explanation:

This question is essentially asking the perimeter of the traingle

We can easily find the sides AC and BA and while you can use the distance formula to find the last side this is a right triange so we will take an easier approach

So because AC has the same y we can very easily figure out how far apart they are by subtracting (or counting) the x values

For me I got AC= 15

AB is kind of the same deal but instead subtract the y value

I got BA= 8

We can now use the a^2+b^2=c^2 formula to get the length of the last side

8^2+15^2=c^2

This means that 289=c^2

take the square root of both sides to get

c=17

The final step is to get the perimeter which is 17+8+15 or 40  

Answer:

x = 17

Step-by-step explanation:

4x-10 and 58 are alternate interior angles since the lines are parallel

Alternate interior angles are equal.

4x-10 = 58

Add 10 to each side

4x-10 +10 = 58+10

4x = 68

Divide each side by 4

4x/4 = 68/4

x = 17

17

Answer:

a) 12 lb

Step-by-step explanation:

First we find the lb for the chicken

5 * $3 = $15

Then we subtract it from the total amount of money Mark has

75$ - $15 = $60

Mark has 60$ remaining to spend on salmon

60 divided by 5 = 12

So he can buy 12 lb of salmon

Answer:

k-k-k-kabbajje!

Step-by-step explanation:

Answer: True

Step-by-step explanation:

The scale factor between shapes is the number that when multiplied by the dimensions of the original shape will give the dimensions of the transformed shape.

Likewise when the dimensions of the transformed shape is divided by this number, it will yield the dimensions of the original shape.

The original shape has a length of 36km.

= 36 * 0.5

= 18 km

This proves that 0.5 is the scale factor because when the length of the original shape was multiplied by it, the result was the length of the transformed shape.

Answer:

Test statistic Z = 1.8099

Step-by-step explanation:

Step(i):-

Given that mean of the Population (μ) = 59.1 miles/gallon

Mean of the sample (x⁻ ) = 59.5

The standard deviation of the Population = 2.89

mean of the sample (n) = 160

Step(ii):-

Test statistic

              [tex]Z = \frac{x^{-}-mean }{\frac{S.D}{\sqrt{n} } }[/tex]

              [tex]Z = \frac{59.5-59.1 }{\frac{2.89}{\sqrt{160} } }[/tex]

              Z = 1.8099

Test statistic = 1.8099

Answer:

[tex]f(x) = 12(1.25)^{x}[/tex]

Step-by-step explanation:

The number of oak trees after x years is given by a function in the following format:

[tex]f(x) = A(1+r)^{x}[/tex]

In which A is the initial number of oak trees, and r is the growth rate, as a decimal.

A park started with 12 oak trees

This means that [tex]A = 12[/tex]

The number of oak trees increased at a rate of 25% each year.

This means that [tex]r = 0.25[/tex]

So

[tex]f(x) = A(1+r)^{x}[/tex]

[tex]f(x) = 12(1+0.25)^{x}[/tex]

[tex]f(x) = 12(1.25)^{x}[/tex]

Answer/Step-by-step explanation:

Given:

[tex] \frac{4}{x} - \frac{3}{y} = 1 [/tex] ---› Equation 1

[tex] \frac{8}{x} + \frac{9}{y} = 7 [/tex] ---› Equation 2

Solution:

✔️Equation 1 × 3:

[tex] \frac{4}{x}*3 + \frac{3}{y}*3 = 1*3 [/tex]

[tex] \frac{12}{x} + \frac{9}{y} = 3 [/tex] ---› Equation 3.

✔️Equation 2 + Equation 3:

[tex] \frac{8}{x} + \frac{9}{y} = 7 [/tex] ---› Equation 2

[tex] \frac{12}{x} + \frac{9}{y} = 3 [/tex] ---› Equation 3.

Thus:

[tex] \frac{-4}{x} = 10 [/tex]

Cross multiply

[tex] 10x = -4 [/tex]

Divide both sides by 10

[tex] x = -\frac{4}{10} [/tex]

[tex] x = -\frac{2}{5} [/tex]

✔️Find y:

Substitute x = -2/5 into equation 1

[tex] \frac{4}{x} - \frac{3}{y} = 1 [/tex] ---› Equation 1

[tex] \frac{4}{\frac{-2}{5}} - \frac{3}{y} = 1 [/tex]

[tex] \frac{4}*{\frac{5}{-2}} - \frac{3}{y} = 1 [/tex]

[tex] -10 - \frac{3}{y} = 1 [/tex]

Add 10 to both sides

[tex] - \frac{3}{y} = 1 + 10 [/tex]

[tex] \frac{-3}{y} = 11 [/tex]

Cross multiply

[tex] 11y = -3 [/tex]

Divide both sides by 11

[tex] y = -\frac{3}{11} [/tex]
