Five apples and four oranges cost $11.80. One apple and six oranges cost $9.90. how much does one orange cost?

Answers

Answer 1

Answer:

the cost of orange is 170

Answer 2

Answer:

One orange costs $1.45.

Step-by-step explanation:

Since there are two variables, you have to set up a 2 variable equation.

Let's let a = apples and o = oranges.

So, we can set up this problem as:

5a + 4o = 11.80

1a  + 6o = 9.90

You can solve a 2-variable equation using either elimination or substitution. Here, I think it's easier to use substitution. To do that we have to substitute one variable with an equation that uses only the other so that we only have one variable.

We can manipulate our second equation so that it is:

a = 9.90 - 6o

Then, we can plug this in for a in the first equation. So,

5 (9.90 - 6o) + 4o = 11.80

49.5 -30o +4o = 11.80  (Distribute the 5)

49.5 - 26o = 11.80  (Combine like terms)

-26o = -37.7 (Subtract 49.5 from both sides)

o = 1.45 (Divide by -26)

o = 1.45

So, an orange costs $1.45.

given the function f(x)= √x+7, find the value of x when f(x)=1

Answers

f(x) = 1, so we make the entire equation equal 1.

1 = sqrt(x) + 7

To make x by itself subtract 7 from both sides

-6 = sqrt(x)

Square both sides to remove sqrt from x.

Answer:Function to be graphed is,

h(x) = 2(x - 3)²

Function 'h' is a quadratic function.

Since, the coefficient of the leading term (term with the highest power) is positive, parabola will open upwards.

Both the ends of the parabola will be upwards (towards positive infinity).

As x approaches to negative infinity, h(x) approaches to positive infinity.

As x approaches to positive infinity, h(x) approaches to positive infinity.

Step-by-step explanation:

X+Y=90°

Y= x-20

2X=110°

X=55°

55°+Y=90°

Y=35°

Answers

Answer:

A

Step-by-step explanation:

Step 1, Identify the coordinates of each vertices in the pre image

A ( -2 , 3 )

B ( 1 , 3 )

C ( 3 , -6 )

D ( -4 . -6 )

Step 2 apply dilation.

To apply the dilation we multiply the x and y values by the scale factor. ( assuming that the dilation is about the origin. )

The scale factor is 2 so we multiply the x and y values of the coordinates by 2, which is as simple as it sounds.

A ( -2 , 3 ) -------> A' ( -4 , 6 )

B ( 1 , 3 ) --------> B' ( 2 , 6 )

C ( 3 , -6 ) ---------> C' ( 6 , -12 )

D ( -4 , -6 ) ----------> D' ( -8 , -12 )

Hence the new coordinates are A' ( -4, 6 ), B' ( 2 , 6 ), C' ( 6 , -12 ), D' ( -8 , -12) Which corresponds with answer choice A

Kayla is painting a room that is 12 feet long and 12 feet wide. The ceiling in the room is 8 feet high. The cost of painting the walls and door is $0.33 per square foot. The cost of painting the ceiling is $0.66 per square foot. Enter the cost, in dollars, for Kayla to paint the room.​

Answers

Answer: $221.76

Step-by-step explanation:

Each wall has a length of 12 and a height of 8 and there are 4 walls

(12 x 8) x 4 = 384 sq ft

multiply sq ft by cost ($0.33)

384 x 0.33 = $126.72 for the walls and door

The ceiling has a length of 12 and a width of 12

12 x 12 = 144 sq ft

multiply sq ft by cost ($0.66)

144 x 0.66 = 95.04

add the costs

126.72 + 95.04 = $221.76 total

It takes 8 workers 12 days to build a wall work out how many days it would take 3 workers to complete the same job

Can anyone please help?

Answers

Answer: 4.5 days or 4 1/2 days

Step-by-step explanation: We can use cross product property, to solve this. Workers to Days remember that  

❍ Question -:

If 8 workers can build a wall in 12 days. How many days will it take 3 workers to build the same wall ?

❍ Explanation -:

In this question we are provided that 8 workers can finish a piece of work in 12 days. We are asked to calculate how many days it will take 3 workers to complete the same work.

We can solve this question using two methods :

Unitary MethodMethod of proportion

[tex] \small \green{ \underline{ \underline{\bf{ Unitary \: Method}}}}[/tex]

8 workers can build a wall in 12 days

1 worker can build a wall in 12 × 8 days

3 workers can build a wall in [tex]\dfrac{12 × 8}{3}[/tex] = 32 days.

Hence, If 8 workers can build a wall in 12 days. 3 workers will take 32 days to build the same wall.

[tex] \rule{47mm}{4pt}[/tex]

[tex] \small \orange{ \underline{ \underline{\bf{ Method \: of \: proportion }}}}[/tex]

Let us assume that 3 workers can build a wall in x days.

[tex] \begin{array}{ cc } \bf{Number \: of \: workers} & \bf{Number \: of \: days} \\ 8 &12 \\ 3&x \end{array}[/tex]

Ratio of workers = Inverse ratio of days

[tex] \small\sf{ 8 : 3 :: x : 12}[/tex]

Product of mean = Product of extreme

[tex] \rightarrow \small\rm{ 3 \times x = 8 \times 12}[/tex]

[tex] \rightarrow{x \: }\small\sf{ = \dfrac{8 \times 12}{3} = 32 \: days } [/tex]

Hence, If 8 workers can build a wall in 12 days. 3 workers will take 32 days to build the same wall.
