A fruit stand has to decide what to charge for their produce. They need $10, for 4 apples and 4 oranges. They also need $15 for

6 apples and 6 oranges. We put this information into a system of linear equations.
Can we find a unique price for an apple and an orange?

Please help me solve the problem

Answer:

x = $\sqrt{2}$ ; y = 2

Step-by-step explanation:

You have a 45 -45 - 90 triangle. There are two things to know"

1. The hypothenuse = leg × $\sqrt{2}$

2. The legs are equal.

The hypothenuse is opposite the right angle that is "y" in this problem.

Hypothenuse = leg × $\sqrt{2}$

= $\sqrt{2} \sqrt{2} = \sqrt{4} = 2$

The legs are =

Therefore x = $\sqrt{2}$

Answer:

58.03

Step-by-step explanation:

What I did first to make it easier was make 5.5 to .055 and when you multiply those two together you get 3.025 which if you round it up becomes 3.03 and when you add 55 you get 58.03

Please help calculate the total surface area. Thanks

Answer: 70cm³

EXPLANATION:

1/2 x base x height x 2 (this is to find the surface area of one of the triangular faces since the other side of the triangular shape has the same measurements you should multiply it by 2 straight away since it makes it easier for you)

1/2 x base x height x 2

1/2 x 3 x 3 x 2 ← <em>(to get the height of the triangle substract 7 from 10)</em>

1/2 x 18 ←<em> (multiply 3x3x2=18) </em>

9cm³ ←<em>(since 18 is 2x9 your answer is 9cm³)</em>

<em></em>

1/2 x base x height x 2 (this is to find the surface area of the other triangular face with different measurements and since the other side of the triangular shape has the same measurements you should multiply it by 2 straight away since it makes it easier for you)

1/2 x base x height x 2

1/2 x 4 x 3 x 2 ← <em>(to get the height of the triangle substract 7 from 10)</em>

1/2 x 24 ←<em> (multiply 4x3x2=24) </em>

12cm³ ←<em>(since 24 is 2x12 so your answer is 12cm³)</em>

<em></em>

Then next you have to find the surface area of one face of the rectangle and multiply it by 2 since the back side of the rectangle has the exact same measurements. The formula to find the area of a rectangle is area= length x breath

A= 3x7= 21cm³

then find the area of the other rectangular face with different measurements and multiply it by 2 since the back side of the rectangle has the exact same measurements. The formula to find the area of a rectangle is area= length x breath

A= 4x7= 28cm³

<u>FINALLY</u>

add all the areas of the faces you have found and you'll get the total surface area!

<u>9+12+21+28=70cm³</u>

Thank you! I hope you understood something and I hope you have a great day! good luck!
