Answer:

? ≈ 24°

Step-by-step explanation:

using the sine ratio in the right triangle

sin? = $(opposite)/(hypotenuse)$ = $(11)/(27)$ , then

? = $sin^(-1)$ ( $(11)/(27)$ ) ≈ 24° ( to the nearest degree )

12. A cereal company decided to make an odd-shaped box for a promotion they are doing. The new design is a rectangular prism with length of 10 cm, width of 8 cm, and height of 4 cm. and attached to the rectangular prism is a cylinder with a radius of 2 cm. and a height of 10 cm. How much cereal (in L) will fit in the box?

Answers

This one odd cereal box. We are asked to find the volume of the "box". This can be answered in 2 parts. The total volume is the sum of the rectangular prism volume and the volume of the cylinder. The volume of the rectangular prism is 8x4x10 = 320 cm^3. Then the volume of the cylinder is $\pi r^(2) h = V$ . The volume of the cylinder is then 125.66. The total volume is then 445.66 ml (Note: ml = cm^3). Then V = 0.45L

Solve the following system of equations by substitution and select the correct answer below: 4x − 6y = 28 8x − 4y = 24

Answers

Answer:

the solution is the point $(1,-4)$

Step-by-step explanation:

we have

$4x-6y=28$

isolate the variable x

$4x=28+6y$

$x=7+1.5y$ -----> equation A

$8x-4y=24$ -----> equation B

substitute the equation A in equation B

$8(7+1.5y)-4y=24$

$56+12y-4y=24$

$12y-4y=24-56$

$8y=-32$

$y=-4$

Find the value of x

$x=7+1.5(-4)=1$

the solution is the point $(1,-4)$

According to my calculation it should be C: x= 1 and y = - 4
