Simplify -6/3 divided by 2/-9

Resposta: 30

Explicação passo a passo:

Dado o seguinte:

Preço para atingir a meta = $ 20

Penalidade por falta de alvo = $ 10

Se 80 tiros forem disparados e os participantes receberem $ 100.

Número de vezes que o participante atinge o alvo.

Deixe o número de erros = m

Deixe o número de acertos = h

h + m = 80 - - - - (1)

20h - 10m = 100 - - - (2)

h = 80 - m

Substitua h = 80 - m em (2)

20 (80 - m) - 10m = 100

1600 - 20m - 10m = 100

-30m = 100 - 1600

-30m = - 1500

m = 50

De (h = 80 - m)

h = 80 - 50

h = 30

Número de acertos = 30

O participante acerta o alvo 30 vezes

Answer:

6837 cm is less than 68 hm

Step-by-step explanation:

1 hectometres  = 100 meters

1 centimetres = 0.01 meters

Therefore;

6837 centimetres = 6837 × 0.01 meters = 68.37 meter

6837 centimetres = 68.37 meter

Also, we have;

68 hectometres  = 68 × 100 meters = 6800 meters

68 hectometres  = 6800 meters

Therefore,

6837 centimetres = 68.37 meter < 68 hectometres  = 6800 meters

6837 centimetres < 68 hectometres  

6837 cm < 68 hm

6837 cm is less than 68 hm.

Answer:

62

Step-by-step explanation:

well, we start by expressing the number:

a b

we understand that using the above expression, the value of the number is 10a + b

using the information in the question,

a = 3b (1)

and,

11b + 11a = 88 (2) (derived using 10a + b form)

hence, when substituting (1) into (2):

11b + 33b = 88

44b = 88

b = 2 (3)

sub (3) into (1)

a = 6

hence, the number is 62

Answer:

dy/dx = -b/a cot α

Step-by-step explanation:

x² / a² + y² / b² = 1

Take derivative with respect to x.

2x / a² + 2y / b² dy/dx = 0

2y / b² dy/dx = -2x / a²

dy/dx = -b²x / (a²y)

Substitute:

dy/dx = -b²a cos α / (a²b sin α)

dy/dx = -b cos α / (a sin α)

dy/dx = -b/a cot α

Answer:

14.765 units

Step-by-step explanation:

Statements (1), (3), and (4) are correct these are NOT true after using the definition of the numbers.

A number is a mathematical entity that can be used to count, measure, or name things. For example, 1, 2, 56, etc. are the numbers.

As we know,

The integer can be defined as the whole number it can be a negative whole number or a positive whole number for example 2, 4, 1, -8, 0, etc.

It is defined as the numbers in all real numbers which cannot be represented as rational numbers, in other words, the irrational number cannot be expressed in the form of p/q form.

A rational number is a sort of real number that has the form p/q and does not equal zero.

Thus, statements (1), (3), and (4) are correct these are NOT true after using the definition of the numbers.

#SPJ2

Answer:

Step-by-step explanation:

To find the diameter Y of the circle we must first find the radius of the circle

Area of a circle = πr²

where

r is the radius

From the question

Area = 400cm²

Substitute the value into the above formula and solve for the radius

That's

400 = πr²

Divide both sides by π

We have

[tex] {r}^{2} = \frac{400}{\pi} [/tex]

Find the square root of both sides

[tex]r = \sqrt{ \frac{400}{\pi} } [/tex]

radius = 11.28 cm

Since we have the radius we can use it to find the diameter Y using the formula

diameter = radius × 2

radius = 11.28

Y = 11. 28 × 2

We have the final answer as

Answer:

20% loss.

Step-by-step explanation:

Suppose the cost of each banana is $1

Then cost of 12 = $12.

You sell 15 bananas for  $12, therefore the price of each banana is 12/15

= $0.80.

So the loss percent is  (1 - 0.80) * 100

= 20%.

Answer:

loss per part is  $(-156).

Step-by-step explanation:

Given total loss = $(-$12,480)

no of identical parts produced = 80

let the loss per part be x

then, total loss for 80 parts = 80* loss per part  = 80x

given that total loss = $(-$12,480)

80x =  $(-$12,480)

x =  $(-$12,480) /80 = $(-156)

Thus, loss per part is  $(-156).

Here negative sign implies that it is a loss.

Answer:

approximately 114.28 km/h

Step-by-step explanation:

Distance = rate * time (d = rt)

The distance from Ipoh to Tapah is 60 km, and the rate is 100 km/h. Therefore, the time it took to drive from Ipoh to Tapah is:

60 = 100t

t = 0.6 hours

The total distance from Ipoh to Kuala Lumpur is 220 km, and the average rate is 110 km.

Therefore, the time it took to drive from Ipoh to Kuala Lumpur is:

220 = 110t

t = 2 hours

So since we know that the time taken to go Ipoh -> Tapah is 0.6 hours and the time taken to go Ipoh -> Tapah -> Kuala Lumpur is 2 hours, the time taken to go Tapah -> Kuala Lumpur must be:

2 - 0.6 = 1.4 hours

And the distance from Tapah to Kuala Lumpur must be:

220 - 60 = 160 km

So the speed driven from Tapah to Kuala Lumpur must be:

160 = r * 1.4

r ≈ 114.28 km/h

Answer:

114.3 km/h

Step-by-step explanation:

We need to find te average speed from Tapah to Kuala Lumpur.

speed = distance/time

We need to find the distance and time from Tapah to Kuala Lumpur.

Ipoh to Tapah:

100 km/h over a distance of 60 km

Ipoh  to Kuala Lumpur:

110 km/h over a distance of 220 km

The total distance is from Ipoh to Kuala Lumpur.

speed = distance/time

distance = speed * time

time = distance/speed

time = 220 km / 110 km/h = 2 hours

Ipoh to Tapah.

time = distance/speed

time = 60 km / 100 km/h = 0.6 hour

Distance & time from Tapah to Kuala Lumpur:

220 km - 60 km = 160 km

2 hours - 0.6 hours = 1.4 hours

average speed from Tapah to Kuala Lumpur:

speed = distance/time = 160 km  /  1.4 hours

speed = 114.3 km/h

Answer:

Option (B)

Step-by-step explanation:

If we graph the points given in the table, a straight line is obtained which shows that the table given represents a linear function.

Let the two points on the graph are (4, 31) and (8, 37)

Slope of the line passing through these points,

m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

   = [tex]\frac{37-31}{8-4}[/tex]

   = 1.5

Equation of the line passing through a point (4, 31) and slope = 1.5 will be,

y - y' = m(x - x')

y - 31 = 1.5(x - 4)

y = 1.5x - 6 + 31

y = 1.5x + 25

Therefore, Option (B) will be the answer.

Answer:

[tex]\huge\boxed{3x-3}[/tex]

Step-by-step explanation:

[tex]3(x-1)=\\\\\text{Distribute: }\left \{ {{3*x=3x} \atop {3*-1=-3}} \right.\\\\3(x-1)=\boxed{3x-3}[/tex]

The distributive property is a very important property used in algebra.

It states that when we have the statement a(b + c), we can "distribute" the

a by multiplying a times both terms that are inside the parenthses.

So that would give us a(b) + b(c) or ab + bc.

The same process is done here.

Distribute the 3 through both terms to get 3(x) - 3(1) or 3x - 3.

Answer: 42 gallons

Step-by-step explanation:

given data:

average gas mileage/day = 29miles/gallon

distance travelled each day by James = 87miles

How much gas does he use in 14days drive.

solution:

james drives 87miles daily, so in 14 days he would have travelled

= 87miles * 14

= 1218miles travelled.

gas used in 14days

1218miles distance traveled in 14 days

29miles/gallon

= 1218miles / 29miles

= 42gallons of gas have been used by janew to fuel his truck in 14days.

Answer:

A = 1.11

n = - 6

Step-by-step explanation:

[tex] \frac{0,0001\times 1,11}{0,1\times 10^4} = A \times 10^n\\\\

\frac{1\times 1,11}{1\times 10^4} = A \times 10^n\\\\

\frac{1,11}{10^4} = A \times 10^n\\\\

{1,11\times 10^{-4} } = A \times 10^n\\\\

{1.11\times 10^{-6} } = A \times 10^n\\\\[/tex]

Equating like terms on both sides :

A = 1.11

Answer: 5:25

Answer:

x = 18

∠A = 83

Step-by-step explanation:

Since you have a line intersecting two parallel lines, the angles formed from the intersection will be equal to 180.  This means that you can add up the two angle measures and set them equal to 180.

(6x - 35) + (3x + 53) = 180

6x - 35 + 3x + 53 = 180

9x + 18 = 180

(9x + 18) - 18 = 180 - 18

9x = 162

x = 18

Now to solve for ∠A, plug in the x-value and solve.

∠A = 6x - 35

∠A = 6(18) - 35

∠A = 118 - 35

∠A = 83

Answer:

Step-by-step explanation:as we know that arc length is

s=r*∅

as given angle in degree so  convert it in radian we get

angle=2.09 rad

r=3.5 cm

hence we get

s=3.5*2.09 =7.315 cm

perimeter of sector = s +d  where d=2*r=2*3.5=7 cm

perimeter of sector=7.315+7=14.315 cm
