Answer:

Option B

Step-by-step explanation:

For option A:

4 pack of 3.2-ounce servings of applesauce cost $2.50. This implies that 4 × 3.2 ounce = 12.8 ounce servings of applesauce cost $2.50. Hence:

The unit rate = $2.50 / 12.8 ounce = $0.1953 per ounce

For option B:

24-ounce servings of applesauce cost $3.69. Hence:

The unit rate = $3.69 / 24 ounce = $0.15375 per ounce

From the unit rates of option A and option B, option B has a lesser unit rate, hence option B is a better buy.

I really need the answers please help asap
DanielleElmas [232]

Step-by-step explanation:

In a straight line theres 180 degrees and where x is you can tell its an X lines the opposites will be the same.

First you need to work out the triangles 180-122=58 and a triangle is 180 degrees so

58+40=98 180-98=82°

now working out the other triangle.

180-82=98, 43+98=141

180-141=39

and because the opposites will end up the same x=39°

What is the surface area of the triangular prism shown?
Lunna [17]

Answer:

The first step that we are going to do is to solve the area of the top rectangle.  We are given a width of 15 cm and a length of 25 cm so we can just multiply them against each other to get the area.

Area = l * w

Area = 25\ cm * 15\ cm

Area = 375\ cm^2

The second side that we are going to solve for is the bottom rectangle.  We are given a width of 12 cm and a length of 25 cm so lets just multiply them against each other to get the area.

Area = l * w

Area = 25\ cm * 12\ cm

Area = 300\ cm^2

The next area that we are going to determine is the back rectangle which has a width of 9 cm and a length of 25 cm so lets just multiply them against each other to get the area.

Area = l * w

Area = 25\ cm * 9\ cm

Area = 225\ cm^2

The final area that we have to determine are the side triangles.  After determining the area of one triangle we will have to multiply it by 2 to get the area for both of the triangles.  We are given a base of 12 cm and a height of 9 cm so lets just use the formula to find the area.

Area = \frac{1}{2}* b*h

Area = \frac{1}{2}* 12\ cm*9\ cm

Area = 54\ cm^2

Multiply it by two to get the area for both of the triangles.

Area = 54\ cm^2 * 2

Area = 108\ cm^2

Finally, we are onto the last part which is to add up all of the areas and get the surface area after we combine everything.

Area_{total}=375\ cm^2 + 300\ cm^2 + 225\ cm^2 + 108\ cm^2

Area_{total}=1008\ cm^2

Therefore, our final answer is option B, 1008 cm^2

Hope this helps!
