3) Abigail makes a sale of 900.00 naira in a day and Lola makes a sale 720.00 naira what is the ratio of Abigail's sales to Lola's sales??​

Answer:

Step-by-step explanation:

The cost of materials for the least expensive such container is $327.081  .

In the question ,

it is given that

the volume of the container = 10 m³ .

let the width of the container = x

so , the length of the container = 2x

So , base area = 2x*x = 2x²

cost for base = $20

cost for the sides = $12

Since the volume is 10 m³

Volume = base area *  height

10 = 2x² * h

h = 10/2x²

h = 5/x²

The cost of making the container

cost of base = 2x² * (20) = 40x²

cost of sides = [2*2x*(5/x²) + 2*x*(5/x²)](12)

= 360/x

the total cost of the container [tex]=[/tex] cost of base [tex]+[/tex] cost of sides

= 40x² + 360/x

= 40( x² + 9/x)

to get the minimum cost , we differentiate with respect to x and equate to 0

= 40 ( 2x - 9/x²)

2x - 9/x² = 0

2x³ = 9

x³ = 9/2

x³ = 4.5

x = 1.651

Substituting x in the cost equation ,

we get

Cost = 40x² + 360/x

= 40(1.651)² + 360/(1.651)

= 109.032 + 218.049

= 327.081

Therefore , The cost of materials for the least expensive such container is $327.081  .

The system of equation for the given condition is: 5+0.03x = 0.10x, where x is the number of texts.

There is no certain number of texts for which two plans are equal.

Let the number of texts for which two plans amount to same number be = x

Plan A: $5.00 per month charge along with a charge of $0.03 per text.

So, Plan A: 5+0.03x

Plan B: No per month charge but a charge of 0.10 per text.

Plan B: 0.10x

Since the plans amounted to same for x texts. So, the suitable system of equation is,

5+0.03x = 0.10x

Solving the equation we get,

0.10x - 0.03x = 5

0.07x = 5

x = 5/0.07 = 71.42 (approximately)

Since the number of texts cannot be decimal number so there is no such number of texts for which plans are equal.

Answer:

9x-4

Step-by-step explanation:

If a washer and dryer cost $750 and the cost of the washer is two times the cost of the dryer, then the cost of the dryer $250

The total cost of a washer and dryer combined = $750

The cost of the dryer = x

The cost of the washer is two times the cost of the dryer.

The cost of the washer = 2x

Then the equation will be

x + 2x = 750

Add the like terms of the equation

3x = 750

Move 3 to the right hand side of the equation

x = 750/3

x = $250

Hence, if a washer and dryer cost $750 and the cost of the washer is two times the cost of the dryer, then the cost of the dryer $250

The nth term of this quadratic sequence 3, 8, 15, 24, 35, … is 2n

An arithmetic sequence is a sequence of numbers such that the difference of any two successive members of the sequence is a constant.

Confirm if the sequence is quadratic and this is done by finding the second difference

Sequence = 3, 8, 15, 24, 35, …

1st difference = 5, 7, 9, 11

2nd difference = 2, 2, 2

Divide the second difference by 2, and let the value be a

2 ÷ 2 = 1

So the first term of the terms is [tex]n^{2}[/tex]

subtract [tex]n^{2}[/tex] from the sequence gives 2, 4, 6 , 8, 10

The perpendicular slope is the negative reciprocal of the original slope:

For example: the perpendicular slope for y/x is -x/y

In this case, we want the slope from x +4y = 28

x +4y = 28

4y = 28 - x

y = 7 -x/4

If he earned $64 in 8 hours then dividing by 64 by 8 will tell us how much he earned in 1 hour. That gives $8

Using that we can then divide the number of dollars by the amount he receives in 1 hour to see how many hours it was.

So $16 / $8 per hour gives 2 hours

The pair of triangles that can be used to show that the slope of line a is same everywhere is upper half triangles

A triangle is a polygon with three vertices and three sides. The angles of the triangle are formed by the connection of the three sides end to end at a point. The triangle's three angles add up to 180 degrees

The total area that is bounded by a triangle's three sides is referred to as the triangle's area. In essence, it is equal to 1/2 of the height times the base, or A = 1/2 b h.

The pair of triangles in choice C (shown in the figure below) demonstrates that line a has a constant slope throughout.

Let's investigate:

Rise/run = slope

Regarding the initial lower triangle:

Rise = 3.5

Run = 4.5

Slope = 3.5/4.5 ≈ 0.8

For the upper second traingle:

Rise = 4

Run = 5

Slope = 4/5 = 0.8

As a result, it demonstrates that the graph's line's slope is constant throughout.

a) The bearing of Wellington from Gisborne is 232°

b) The bearing of Wellington from Auckland is  175.37°

We are given that AW = 410 km and GW = 400 km.

a) AG  is a transversal intersecting two parallel lines N₁A and N₂B and ∠N₁AG = 115°.

Thus;

∠AGN₂ = 180 − 115 = 65°  

since the sum of the interior angles on the same sides of the transversal intersecting two parallel lines are supplementary.

Thus;

∠N₂GW = 65 + 63 = 128°.

The reflex angle;

∠N₂GWW = 360 − 128° = 232°

b) In  △AGW, we can say that by the sine rule;

(sin∠WAG)/WG = (sin∠AGW)/AG  

Plugging in the relevant values;

(sin∠WAG)/400 = (sin∠63°)/410

To answer this question, you should combine like terms:

Like terms are two or more terms that share the same variable.

J is the variable in this question so add 0.9j to both sides of the equation to get j on one side:

-0.1j + 0.8 = 0.76

Now subtract 0.8 from both sides to isolate j on one side of the equation:

-0.1j = -0.04

Divide both sides by -0.1 to isolate j and your answer should be:

Answer: j = 0.4

The equation of the line is - 175 x + 2 y = - 500

From the question, we have

Point 1 :

x-coordinate, x1 = 6

y-coordinate, y1 = 275

Point 2 :

x-coordinate, x2 = 8

y-coordinate, y2 = 450

We know that,

y-275 = (275-450)/(6-8)*(x-6)

y-275 = 175/2*(x-6)

- 175 x + 2 y = - 500

Slope of a Line :

A line's slope in mathematics is defined as the ratio of the change in the y coordinate to the change in the x coordinate.

Both the net change in the y-coordinate and the net change in the x-coordinate are denoted by y and x, respectively.

As a result, m = change in y/change in x = y/x is the formula for the change in y-coordinate with respect to the change in x-coordinate.

where "m" represents a line's slope.

The line with m as the slope, m and c as the y-intercept is the graph of the linear equation y = mx + c. The values of m and c are real integers in the slope-intercept form of the linear equation.

Step-by-step explanation:

let n be the length then n + 1 is the width

the perimeter (P) of a rectangle is calculated as

P 2(l + w) ← l is length and w is width

given P = 54 , then

2(n + n + 1) = 54 ( divide both sides by 2 )

2n + 1 = 27 ( subtract 1 from both sides )

2n = 26 ( divide both sides by 2 )

The expression that represents the amount of sodium per serving in the new soup is 0.67x milligrams.

The new soup recipe contains 33%, percent less sodium per serving than the old soup recipe. The old soup recipe contained x milligrams of sodium per serving.

The expression that can be used to represent the amount of sodium per serving in milligrams in the new soup can be computed as follows;

Old soup amount of sodium = x milligram

The new soup contains 33% less sodium per serving than the old soup recipe.

Therefore,

amount of sodium per serving in the new soup = x - 33% of x

amount of sodium per serving in the new soup = x - 33 / 100 x

amount of sodium per serving in the new soup = x - 0.33x

Therefore,

amount of sodium per serving in the new soup = x(1 - 0.33)

amount of sodium per serving in the new soup = x(0.67)
