X=hamburgers
y=hotdogs

3y+2x=8.00
AND
2y+3x=8.25

Now we've got a system of equations!

Choose a method to solve it, and I think you'll be good from there.

If you need more guidance to the answer, tell me in the comments.

BEST OF LUCK:)

Help please triangles

andrey2020 [161]

For all of them just use the Pythagorean theorem which is a squared plus b squared equals c squared where c is the hypotenuse (length of the side opposite the right angle) and a and b are legs. Just plug it in and solve for the missing length. For example, 1 would be (12) squared plus (5) squared equals c squared
Simplify to get 144 plus 25=c squared
169 equals c squared
Find the square root of both sides
c=13

What is the approximate volume of the oblique cone? Use TTX =3.14 and round to the nearest tenth.

AleksandrR [38]

Answer:

The volume of given oblique cone is 235.5 cubic units.

Step-by-step explanation:

Volume of oblique cone is same as volume of cone

Consider a cone with 'r' as radius and 'h' height then volume is given as,

Volume of cone = $\frac{1}{3} \pi r^2h$

Given : Oblique cone with radius 5 units and height 9 units.

We have to find the volume of cone.

Volume of cone = $\frac{1}{3} \pi r^2h$

Put given values in above,

Volume of oblique cone = $\frac{1}{3} \pi (5)^2 \times 9$

Volume of oblique cone = $\frac{1}{3} \times 3.14 \times 25 \times 9$

Volume of oblique cone = $3.14 \times 25 \times 3$

Volume of oblique cone = $3.14 \times 75$

Volume of oblique cone = $235.5$

Thus, the volume of given oblique cone is 235.5 cubic units.
