Gre4nikov [31]

Answer:

2.5 cm

Step-by-step explanation:

The volume of a triangular prism is cross section × length.

The cross section area is the triangle area. The triangle length is 4 cm, the height is not given. The length of the triangular prism is 7cm.

4 × h × 1/2 × 7 = 35

14h = 35

h = 35/14

h = 5/2

The height of the triangular cross section is 2.5 cm.

3 Ramón makes nectar for a hummingbird feeder by mixing 8 cups of water with 2 cups of sugar. Tiffany makes nectar by mixing 9 c
Butoxors [25]

Answer:

Tiffany's nectar is more sugary

Step-by-step explanation:

Given

Ramon:

Water = 8\ cups

Sugar = 2\ cups

Tiffany

Water = 9\ cups

Sugar = 3\ cups

Required

The nectar with more sugar

To do this, we simply calculate the fraction of sugar in both nectar.

This is calculated as:

Fraction = \frac{Sugar}{Sugar + Water}

For Ramon:

Fraction = \frac{2}{8 + 2}

Fraction = \frac{2}{10} = 0.20

For Tiffany

Fraction = \frac{3}{3 + 9}

Fraction = \frac{3}{12} = 0.25

From the calculations above:

0.25 > 0.20

Hence: Tiffany's nectar is more sugary

Angelina_Jolie [31]

Answer:∠M in the pre-image corresponds to ∠B in the image.

Step-by-step explanation:

When  we look at the figures , we can see that the three vertices B , C , D are one side as vertices to M , N  ,O .

Clearly , vertex C corresponds to vertex N ( presents in the middle )

Also, point B is at the right from point C .In  Figure L M N O P , vertex M is at the right from vertex N .Thus , vertex M corresponds the vertex B.

It means ∠M in the pre-image corresponds to ∠B in the image.

brain list this answer thankyou:)

weeeeeb [17]

Answer: W= 5000+0.07S

Step-by-step explanation:

Given: A pharmaceutical salesperson receives a monthly salary of $5000 plus a commission of 7% of sales.

Total wages = Monthly salary + 7% of (Monthly sales)

Let salesperson’s monthly wage be W and monthly sales be S.

Then, W = 5000+(0.07) (S)  [Convert percent into decimal by dividing it by 100]

Or W= 5000+0.07S

Required linear equation: W= 5000+0.07S
