Amanda is at a store for apples and bananas. if she buys 6 apples and 5 bananas, it will cost $8.00. is she buys 5 apples and 7 bananas, it will cost $9.50. write and solve a system to determine how much the apples cost

Answers

Answer 1

Answer:

Therefore the cost of each apple is $ 0.50 and each banana is $1.

Step-by-step explanation:

Given , Amanda buys 6 apples and 5 bananas , it will cost $8.00 and if she buys 5 apples and 7 bananas it will cost $9.50.

Let the cost of one apple be =$ x

and the cost of one banana be =$y

According to the problem,

6x+5y=8.........(1)                  5x+7y= 9.50............(2)

Equation (1)×5 - equation (2) × 6

30x +25 y-(30x+42y)= 40-57

⇔30x+25y -30x-42y= -17

⇔-17y =-17

⇔y=1

putting the value of y in equation (1)

6x+5×1=8

⇔6x = 8-5

⇔6x=3

⇔[tex]x =\frac{3}{6}[/tex]

⇔x = 0.50

Therefore the cost of each apple is $ 0.50 and each banana is $1.

11. The perimeter of a rectangle is 60 cm. The length is four times the width. What
are the length and the width of the rectangle?

Answers

Answer:

Length = 24 cm

Width = 6 cm.

Step-by-step explanation:

The formula to compute the perimeter of a rectangle is,

[tex]Perimeter=2(length+width)[/tex]

Given:

Perimeter = 60 cm

width = w

length = 4w

Determine the value of width as follows:

[tex]Perimeter=2(length+width)\\60=2\times(4w+w)\\60=10w\\w=6[/tex]

The value of length is:

[tex]length(l)=4\times w\\l=4\times6\\l=24[/tex]

Thus, the length and the width of the rectangle are 24 cm and 6 cm respectively.

How many cubic feet of concrete are needed to pour 4 cylindrical pillars 5 feet high with a diameter of 4 inches?

Answers

Answer:  1.75 cubic feet concrete is needed.

Step-by-step explanation:

Alright, lets get started.

The volume of the pillar is : [tex]\pi r^2h[/tex]

We have given the height is 5 feet.

We have given the diameter is 4 inches.

So the radius will be : [tex]\frac{4}{2}=2 \ inches[/tex]

Converting inches into feet.

The radius will be : [tex]\frac{2}{12} \ feet[/tex] [tex]= 0.167 feet[/tex]

So the volume of the cylinder will be : [tex]\pi * 0.167^2*5[/tex]

So the volume of the cylinder will be : [tex]0.4380 \ cubic \ feet[/tex]

As there are 4 pillars, so total volume will be : [tex]4*0.4380[/tex]

What is the value of -36÷(-4/9)

Answers

The value of -36 divided by (-4/9) is 81, which is found by multiplying -36 with the reciprocal of (-4/9), giving the result 324/4, which simplifies to 81.

To find the value of -36 divided by (-4/9), you can think of division by a fraction as multiplication by its reciprocal. So, the problem changes from division to multiplication: -36 * (-9/4). To solve this:

First, multiply the numerators: -36 * -9 = 324.

Then, multiply the denominators: 1 * 4 = 4.

Now, divide 324 by 4 to get 81.

Therefore, the value of -36 divided by (-4/9) is 81.

Rectangle 25 feet long. It has a perimeter of 130 feet. What is the area of the basement?

Answers

Final answer:

To find the area of the basement, we started with the given perimeter of 130 feet and the known length of 25 feet and solved for the missing width. Once we determined the width was 40 feet, we used the formula for the area of a rectangle (Area = length × width) to calculate that the basement's area is 1000 square feet.

Explanation:

To solve the question regarding the area of a rectangle where the length is 25 feet and the perimeter is 130 feet, we must first deduce the width of the rectangle using the perimeter formula: P = 2l + 2w (where P is the perimeter, l is the length, and w is the width). Since we know the perimeter (P) and the length (l), we can rearrange this formula to solve for the width (w).

The perimeter formula is expressed as:

130 = 2(25) + 2w

130 = 50 + 2w

2w = 130 - 50

2w = 80

w = 40 feet

Now that we have both the length and the width, we can calculate the area of the rectangle using the formula Area = length × width.

Therefore, the area of the rectangle is:

Area = 25 feet × 40 feet
Area = 1000 square feet

The sum of two numbers is 39 and their difference is 5. Which is the larger number?

Answers

Answer:

22

Step-by-step explanation:

Let x be a number

Other number = 39 -x

x - (39 - x) =5

x - 39 + x = 5

2x = 5 + 39 = 44

x = 44/2

x = 22

Other number = 39 - 22 = 17

Answer:

The larger number = 22

Step-by-step explanation:

Let the two number x and y

The sum of two numbers is 39 can be represented as:

x + y = 39----------------1

The difference of two numbers is 5 can be represented as:

x - y = 5------------------2

x + y = 39----------------1

x - y = 5------------------2

Using Elimination Method and subtracting 2 from 1

x-x + y-(-y) = 39 - 5

0+y+y=34

2y=34

y=34/2

y=17

substituting y=17 in 1

x+17=39

x=39-17

x=22

The larger number = 22


Find the equation of a line that is parallel to line g that contains (P, Q).
the coordinate plane has a line g that passes through the points (-3,2) and (0,5).

3x + y = Q − 3P
x − y = P − Q
x + y = Q − P

Answers

Correct option:

[tex]\boxed{x-y=P-Q}[/tex]

Explanation:

Given that the line we are looking for is parallel to g, then the slope of that line and g is the same, therefore:

So we can write the point-slope form of the equation of the line as follows:

[tex]y-y_{0}=m(x-x_{0}) \\ \\ (x_{0},y_{0})=(P,Q) \\ \\ \\ y-Q=1(x-P) \\ \\ y-Q=x-P \\ \\ \\ Arranging: \\ \\ P-Q=x-y \\ \\ \boxed{x-y=P-Q}[/tex]

Find an equation for the parabola with focus at (-5,-4) and vertex at (-5,-3)

Answers

Answer:

[tex](x+5)^{2}=-4(y+3)[/tex]

Step-by-step explanation:

Given:

Focus point = (-5, -4)

Vertex point = (-5, -3)

We need to find the equation for the parabola.

Solution:

Since the x-coordinates of the vertex and focus are the same,

so this is a regular vertical parabola, where the x part is squared. Since the vertex is above the focus, this is a right-side down parabola and p is negative.

The vertex of this parabola is at (h, k) and the focus is at (h, k + p). So, directrix is y = k - p.

Substitute y = -4 and k = -3.

[tex]-4 = -3+p[/tex]

[tex]p=-4+3[/tex]

[tex]p=-1[/tex]

So the standard form of the parabola is written as.

[tex](x-h)^{2}=4p(y-k)[/tex]

Substitute vertex (h, k) = (-5, -3) and p = -1 in the above standard form of the parabola.

So the standard form of the parabola is written as.

[tex](x-(-5))^{2}=4(-1)(y-(-3))[/tex]

[tex](x+5)^{2}=-4(y+3)[/tex]

Therefore, equation for the parabola with focus at (-5,-4) and vertex at (-5,-3)

A circle and a square each have a perimeter of 160 feet. Which has the greater area and by how much

Answers

Answer:

[tex]The \: circle \: has \: a \: bigger \: area \: by \approx 438 \: {ft}^{2} [/tex]

Explanation:

[tex]Diameter \: of \: circle:160 \div 3.14 \approx 51 \: ft \\ Area \: of \: circle : \frac{3.14 \times {51}^{2} }{4} \approx 2038 \: {ft}^{2} \\ Sides \: of \: square:160 \div 4 = 40 \: ft \\

Area \: of \: square: \: {40}^{2} = 1600 \: {ft}^{2} \\ 2038 - 1600\approx 438 \: {ft}^{2} [/tex]

Final answer:

Comparing the areas of a circle and a square with the same perimeter of 160 feet, the circle has a greater area by approximately 435.75 square feet.

Explanation:

We are comparing the areas of a circle and a square which both have a perimeter of 160 feet. For the square, since the perimeter (P) is 160 feet, each side (s) will be P/4, which gives us s = 40 feet. The area of the square (Asquare) is s², so Asquare = 40² = 1600 square feet.

For the circle, the perimeter is the circumference (C), which is 160 feet. The formula for the circumference of a circle is C = 2πr, where r is the radius. So, 160 = 2πr, giving us r = 160/(2π). The area of the circle (Acircle) is πr², so Acircle = π(160/(2π))². After calculation, we find that Acircle ≈ 2035.75 square feet.

Comparing the two areas, the circle has a greater area than the square by Acircle - Asquare ≈ 2035.75 - 1600 ≈ 435.75 square feet.
