Given :

The length of Dwight's garden is 12.5 meters.

Dwight measured it but made a measurement error of 6%.

To Find :

The lowest and highest measurement Dwight could have made.

Solution :

Error in length measuring is :

[tex]\Delta \ l = 12.5\times 0.06 \\\\\Delta \ l = 0.75\ m[/tex]

Therefore, the lowest and highest measurement he could have is 12.5 - 0.75  = 11.75  meters and 12.5 + 0.75 = 13.25  meters.

Answer:

X=4

Step-by-step explanation:

4(x+12) = 19x-12

4x+48= 19x-12

sub 4x from both sides

48= 15x-12

add 12 to both sides

60=15x

divide 15 from both sides

and 60/15 =4

Answer:

[tex]4(x + 12) = 19x - 12 \\ 4x + 48 = 19x - 12 \\ 4x - 19x = - 12 - 48 \\ - 15x = - 60 \\ x = \frac{60}{15} \\ x = 4[/tex]

Answer:

4) Neither

Answer:

5. 216, 1416

6. 448.5 g

Step-by-step explanation:

5.

Price of 1 item: 1200

GST = 18%

18% of 1200 =

= 0.18 * 1200

= 216

Amount of tax: 216

Total price = original price + GST

Total price = 1200 + 216 = 1416

6.

Weight of 1 item: 17 1/4 g

Weight of 26 items = 26 * 17 1/4 g

26 * 17.25 g = 448.5 g

Answer:

Let x be the number

"five times a number"

5x

"six less than five times a number"

5x-6

"is at least 29" >29 (greater than or equal too)

5x - 6 > 29

5x > 35 (add +6 to both sides retains the dense if the inequality)

x>7 (divide both sides by +7 retains the sense of Inequailty)

Check:

Is 5(7) - 6 > 29?

35 - 6 > 29 ?

29 > 29? yes, they are equal.

Try 50:

Is 5(50) - 6 > 29 ?

250 - 6 > 29?

244 > 29 ? yes

Answer:

5x - 6 = 29

Answer:

one pound of apple cost $2.5

Step-by-step explanation:

Let the amount they both spent at the grocery store be y and x be the price of apples per pound.

Since Tara bought 5 pounds of apples, 5x = y (1) and Ashley bought 3 pounds of apples and $5 worth other groceries, 3x + 5 = y (2).

Equating both expressions, 5x = 3x + 5

collecting like terms,

5x - 3x = 5

2x = 5

dividing both sides by 2, we have

x = 5/2

x = 2.5

So one pound of apple cost $2.5

Answer:

Answer: 153

Step-by-step explanation:

When we have a group of N elements, the total number of combinations of K elements ( K ≤ N) is:

[tex]C (N, K) = \frac{N!}{(N-k)!*K!}[/tex]

Where N! = N*(N - 1)*(N - 2)*...*2*1

In this case, we have a group of 18 people (then N = 18) and we want to see how many different combinations of 2 we can make (K = 2).

Using the above equation we get:

[tex]C(18, 2) = \frac{18!}{(18 - 2)!*2!} = \frac{18!}{16!*2!} = \frac{18*17}{2} = 9*17 = 153[/tex]

There are 153 different ways in which the manager can do this.

Answer:

La situación está representada por el siguiente sistema:

[tex]y = 20+2\cdot x[/tex]

[tex]y \ge 50[/tex]

Donde:

[tex]x[/tex] - Cantidad de rosas vendidas semanalmente.

[tex]y[/tex] - Ganancia semanal, medida en dólares.

Step-by-step explanation:

De acuerdo con el enunciado, Nita gana una cantidad fija cada semana por pasear al perro de su vecino, con un monto de $ 20, mientras que gana en función de la cantidad de rosas a vender, con un valor unitario de $ 2. Si ella desea ganar al menos $ 50, por tanto, se requiere construir el siguiente sistema, conformado por una ecuación y una inecuación:

[tex]y = 20+2\cdot x[/tex] (1)

[tex]y \ge 50[/tex] (2)

Donde:

[tex]x[/tex] - Cantidad de rosas vendidas semanalmente.

[tex]y[/tex] - Ganancia semanal, medida en dólares.

Answer:

Alyssa=225

Eric=680

Step-by-step explanation:

The money Alyssa has $660 and  Eric has $245.

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

Given that, Alyssa has $75 less than three times Eric.

Let $x be the money Eric had.

Then Alyssa has 3x-75

Together they have $905.

So, x+3x-75=905

4x=905+75

4x=980

x=980/4

x=$245

Money Alyssa has 3x-75

= 3×245-75

= 735-75

= $660

Therefore, money Alyssa has $660 and  Eric has $245.

Answer:

x° = 11°

Z FGI = 60°

Step-by-step explanation:

If GH bisects Z FGI

then Z FGH = Z HGI

or, (3x - 3)° = (4x - 14)°

or, 3x° - 4x° = - 14° + 3°

or, x° = 11°

Z FGI = 33° - 3° + 44° - 14°

= 60°

Answer:

x=7; y=21

Step-by-step explanation:

These angles are congruent so:

7y-3=2x+4

We need to find x, and AB and DC are congruent, so:

3x+3=6x-18

Add 18 to both sides:

3x+21=6x

Subtract 3x from both sides:

3x=21

Divide by 3:

x=7

Substitute:

7y-3=2(7)+4

Simplify Like-Terms:

7y-3=18

Add 3 to both sides:

7y=21

Divide both sides by 7:

y=21

Step-by-step explanation:

Angle at Center = 2 * Angle at Circumference

Therefore B = 2A.

When B = 100°, A = 100°/2 = 50° (B),

When A = 48°, B = 2(48°) = 96°. (C)

Answer:

The dimensions of the cube would be:

Step-by-step explanation:

For this exercise, I suppose the measure of each cube is 1 unit, because there no says what is (you can replace it for ft, in, or another unit you need). How the big cube is formed by the 100.000 cubes smaller, and how a cube has its three measures equal: base, height, and width, you only need to obtain the cubic root of the total cubes (you use cubic root because you're gonna calculate a cube, for example, if you'd wanna calculate a square, you must obtain the square root of the total cubes):

How each cube measure is 1 unit, when you calculate the volume of the cube with the value obtained, you must obtain the total of the cubes:

In this form, you know the answer 46,41588834 is the right answer. I use the number with just two decimals (46,42 approximately) but you can use the complete number if you need.

Answer:

(3,-9)

Step-by-step explanation:

The given equations are :

−5x−3y=12 (1)

y=x−12 ....(2)

Put the value of y from equation (2) in equation (1)

−5x−3(x-12)=12

-5x-3x+36 = 12

Taking like terms together

-5x-3x = 12-36

-8x = -24

x = 3

Put the value of x in equation (2)

y=3−12

y = -9

Hence, the solution of the above equations is x = 3 and y = -9 or (3,-9).
