Answer: BRAINLIEST PLEASE

her supply has 18 pounds

Explanation:

Assume that the number of pounds in her supply is x.

We are given that:

She uses 1/3 x in salted mix and 2/9 x in unsalted mix.

This means that:

Total amount used = 1/3 x + 2/9 x = 5/9 x of her supply

Now, we are also given that:

She used 10 pounds of her supply.

This means that:

5/9 x = 10

5x = 9*10 = 90

x = 18 pounds

Hope this helps :)

The number of pounds of seeds in her supply is 18

Given:

let

her total supply = x

Supply of salted snack = 1/3x

Supply of unsalted snack = 2/9x

Total pounds of sunflower seed = 10

Total supply of sunflower seeds = salted snack + unsalted snack

10 = 1/3x + 2/9x

10 = (3x + 2x) / 9

10 = 5/9x

divide both sides by 5/9

x = 10 ÷ 5/9

x = 10 × 9/5

= (10 × 9) / 5

= 90/5

= 18

x = 18

Therefore, number of pounds of seeds in her supply is 18

Answer:

Base: 16 cm

Height: 48 cm

Step-by-step explanation:

Let's call the length of the base b, and the length of the height h. Since the formula for the area of a triangle is bh/2, you can set up the following equations:

[tex]h=3b\\\dfrac{bh}{2}=384\\ \dfrac{b(3b)}{2}=384\\\dfrac{3b^2}{2}=384\\3b^2=768\\b^2=256\\b=16\\h=16\cdot 3=48[/tex]

Answer:

$7.20

Step-by-step explanation:

The first step is to convert 1 1/4 to decimal form. 1/4=0.25, which when added to the 1 gives a total weight of 1.25 pounds. Dividing this by the price to find the unit price, you get 9/1.25=$7.20 per pound of turkey. Hope this helps!

Unit price is the price when something is $1, so what you need to do is 9/1.25. The answer is $7.20, so that is the unit rate. I hope this helps.

Answer:

21.75 km/h

Step-by-step explanation:

Let's call the aircraft carrier speed 'x', so the speed of the container ship is 'x+8'

The distance travelled can be found with the product of the speed and the time travelled: d = v * t

The aircraft carrier travelled five hours, so the distance travelled is:

d1 = x * 5 = 5x

Then, the container ship travelled seven hours, so the distance travelled is:

d2 = (x+8)*7 = 7x + 42

As they travelled in opposite directions, the distance between then is the sum of these distances, and it is equal 303 km, so we have that:

d1 + d2 = 303

5x + 7x + 42 = 303

12x = 261

x = 21.75 km/h

Answer:

The aircraft carrier's speed was 13 km/h

Step-by-step explanation:

The parameters given in the question are;

Time of departure of the aircraft carrier = 5 hours before the container ship

Speed of the container ship = 8 km/h faster than the aircraft carrier

Distance between the two ships after 7 hours = 303 km

Let the speed of the aircraft carrier be Z

∴ The speed of the container ship = Z + 8

Since the aircraft carrier left port 35 travelling North 5 hours earlier we have;

Total time of travel of the aircraft carrier at the time of measurement of the distance between the two ships = 5 + 7 = 12 hours

Therefore, since both ships are moving in opposite direction on the same line path, we have;

303 = 12×Z + 7 × (Z + 8) = 12·Z + 7·Z + 56

19·Z = 303 - 56 = 247

∴ Z = 247/19 = 13 km/h

Hence, the aircraft carrier's speed was 13 km/h.

Answer:

Step-by-step explanation:

Given the surdic equation as shown [tex]\frac{\sqrt{6}+\sqrt{11} }{\sqrt{5}+\sqrt{3} }\\[/tex]

To find the quotient, we will rationalize by multipying both numerator and denominator of the function by the conjugate of the denominator.

Given the denominator [tex]\sqrt{5}+\sqrt{3}[/tex], its conjugate will be [tex]\sqrt{5}-\sqrt{3}[/tex]

Multiplying through by [tex]\sqrt{5}-\sqrt{3}[/tex], we have;

[tex]= \frac{\sqrt{6}+\sqrt{11} }{\sqrt{5}+\sqrt{3} } * \frac{\sqrt{5}-\sqrt{3} }{\sqrt{5}-\sqrt{3} }\\[/tex]

[tex]= \frac{\sqrt{30}- \sqrt{18}+\sqrt{55}-\sqrt{33}}{2}\\= \frac{\sqrt{30}- \sqrt{9*2}+\sqrt{55}-\sqrt{33}}{2}\\= \frac{\sqrt{30}- 3\sqrt{2}+\sqrt{55}-\sqrt{33}}{2}[/tex]

Step-by-step explanation:

a.

A diagonal of a square inscribed in a circle is the diameter.

So, to find the diameter we know if we separate the square into two different 45-45-90 degree triangles where a and b is 8[tex]\sqrt{2}[/tex]. Use the 45-45-90 degree theorem shown in picture to find that the diagonal 8[tex]\sqrt{2}[/tex] times [tex]\sqrt{2}[/tex] equals 16.

So, the diagonal is 16, thus the diameter is 16.

b.

Multiply 8[tex]\sqrt{2}[/tex] times 4 to get 32[tex]\sqrt{2}[/tex] as the perimeter as there are 4 sides which are equal to RS

c.

The circumference of a circle is the diameter times [tex]\pi[/tex]. The diameter we know from a, which is 16. So, it is 16[tex]\pi[/tex]

Answer:

Since a and b are constant the answer is 6.5

Step-by-step explanation:

g(x) = 2x + 5

g(x) = y

y = 2x + 5

y - 5 = 2x

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

[tex]g^{-1}[/tex](x) = [tex]\frac{x-5}{2}[/tex]

8 = h(1) and h(3) = 26

26 = a(3) + b

a = b

6.5 = 6.5

26 = 6.5(3) + 6.5

26 = 19.5 + 6.5

26 = 26

Answer:

3 right and 5 down

Step-by-step explanation:

=================================================

Short explanation:

Plug z = 2 into the equation and you'll find that

z^3 + 8 = 2^3 + 8 = 8+8 = 16

but the result should be 0 since the original equation has 0 on the right side. Therefore, z = 2 is not a solution.

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

Longer explanation:

Solve the equation for z to find the three roots.

z^3 + 8 = 0

(z+2)(z^2 - 2z + 4) = 0 ... sum of cubes factoring rule

z+2 = 0 or z^2 - 2z + 4 = 0

z = -2 or z^2 - 2z + 4 = 0

We see that z = -2 is one root. To find the other two roots, use the quadratic formula to solve z^2 - 2z + 4 = 0 for z

[tex]z = \frac{-b\pm\sqrt{b^2-4ac}}{2a}\\\\z = \frac{-(-2)\pm\sqrt{(-2)^2-4(1)(4)}}{2(1)}\\\\z = \frac{2\pm\sqrt{-12}}{2}\\\\z = \frac{2\pm\sqrt{-1*4*3}}{2}\\\\z = \frac{2\pm\sqrt{-1}*\sqrt{4}*\sqrt{3}}{2}\\\\z = \frac{2\pm i*2*\sqrt{3}}{2}\\\\z = \frac{2\pm 2i*\sqrt{3}}{2}\\\\z = \frac{2(1\pm i*\sqrt{3})}{2}\\\\z = 1\pm i\sqrt{3}\\\\z = 1+ i\sqrt{3} \ \text{ or } \ z = 1- i\sqrt{3}\\\\[/tex]

Therefore, the three roots of z^3+8=0 are [tex]z = -2, \ z = 1+i\sqrt{3}, \ z=1-i\sqrt{3}[/tex]

The value z = 2 is not part of the list of solutions.

We can verify each solution by plugging it back into the original equation. For instance, with z = -2, we get

z^3 + 8 = 0

(-2)^3+8 = 0

-8+8 = 0

0 = 0 ... solution is confirmed.

I'll let you check the other solutions.
