Answer:

You bought 5 pounds of bananas

Step-by-step explanation:

Firstly, we assign variables.

Let the number of pounds of bananas bought be b and the number of pounds of apple bought be a .

One more pound of apples than bananas were bought.

Mathematically this means a - b = 1 or a = b+ 1 .........(i)

The total cost of apples bought is 3.4 * a = $3.4a

The total cost of bananas bought is 2.30 * b = $2.30b

Now the addition of both equals $31.90

Thus, we have;

3.4a + 2.3b = 31.9 •••••••••(ii)

From i, we can substitute for a

3.4(b+1) + 2.3b = 31.9

3.4b + 3.4 + 2.3b = 31.9

5.7b + 3.4 = 31.9

5.7b = 31.9 - 3.4

5.7b = 28.5

b = 28.5/5.7

b = 5 pounds

Annie is creating a stencil for her artwork using a coordinate plane. The beginning of the left edge of the stencil falls at (−1
ludmilkaskok [199]

Answer: 8 -1

Step-by-step explanation:

referring to brainly.com/question/16983018

The given parameters are;

Location of the beginning of the left edge of the stencil = (-1, 2)

Location of the detail = (2, 1)

Ratio of detail distance from beginning to detail to distance from beginning to stencil end = 1:2

Distance from beginning to detail = √((-1 - 2)² +  (2 - 1)²) = √10

Given that the ratio of the length of the detail to the length of the end after the detail is 1:2 therefore;

√10:Length of stencil side = 1:2

Distance from detail to stencil end = 2×√10

Which gives;

Slope of line = tan⁺¹((2 - 1)/(-1 - 2)) = tan⁺¹(-1/3) = -18.435°

x-coordinates of the end of the stencil = 2√10 × cos(-18.435°) + 2 = 8  

y coordinates of the end of the stencil = 2√10 × sin(-18.435°) + 1 = -1  

The coordinates of the end of the stencil = (8, -1)

What is the volume of this triangular prism? 313.6cm3 506.8cm3 5,676.16cm3 11,352.32cm3
lyudmila [28]

The question is incomplete. Here is the complete question:

What is the volume of this triangular prism?

Base length = 22.4 cm

Height = 18.1 cm

Length = 28 cm

A) 313.6 cm3

B) 506.8 cm3

C) 5,676.16 cm3

D) 11,352.32 cm3

Answer:

V=5,676.16\ cm^3

Step-by-step explanation:

Given:

The base of the prism is triangular with base length equal to 22.4 cm and height 18.1 cm. The length of the prism is 28 cm.

The volume of a triangular prism is defined by the formula:

V=(Area\ of\ base)\times (length)

Here, the base is triangular and the area of a triangle is:

A=\frac{1}{2}base \times height

Therefore,  the volume of the triangular prism is given as:

V=\frac{1}{2}(base\times height\times length)

Now, plug in the given values and solve for the volume 'V'.

V=\frac{1}{2}(22.4\ cm\times 18.1\ cm\times 28\ cm)\\\\V=\frac{1}{2}(11,352.32\ cm^3)\\\\V=5,676.16\ cm^3

Therefore, the correct answer is the third option.

V=5,676.16\ cm^3
