We went to the market to buy some fruit. We decided to buy some apples, strawberries, and oranges. If we buy 2 apples, 3 boxes o

f strawberry, and 4 oranges, the fruit would cost $15.30. If we buy 1 box of strawberry, 4 apples, and 2 oranges, the fruit would cost $10.90. If we buy 1 orange, 5 apples and 2 boxes of strawberry, the fruit would cost $13.70.

Answer:

The answer is below

Step-by-step explanation:

Let x represent the cost of apples, y represent the cost of strawberries and z represent the cost of oranges.

The money used to buy 2 apples, 3 boxes of strawberry, and 4 oranges is represented as:

2x + 3y + 4z = 15.3         (1)

The money used to buy 4 apples, 1 boxes of strawberry, and 2 oranges is represented as:

4x + y + 2z = 10.9       (2)

The money used to buy 5 apples, 2 boxes of strawberry, and 1 oranges is represented as:

5x + 2y + z = 13.7        (3)

Solving equation 1, 2 and 3 simultaneously gives:

x = $1.5, y = $2.5 and y = $1.2

The cost of orange is $1.5, cost of strawberry = $2.5 and cost of orange = $1.2

WILL GIVE BRAINLIST please help i dont remember this​
sergiy2304 [10]

Answer:

(3,5)

Step-by-step explanation:

Here we are asked to find the reflection of Point P(-1,5) along the line represented by x=1

Please refer to the image attached with answer.

We have point P (-1,5) , the line x=1 and the Point R which is the reflection of P across x=1

now we can see that P is 2 units towards left of the line x=1. hence its reflection across x=1 will be 2 units away towards right of line. 2 units away , the x coordinate will be 1+2 = 3

Hence the x coordinate is 3 and y coordinate remains the same. Hence the coordinates of R will be (3,5)

A triangle has 3 sides, 10000, 1000, 10x. Find 10x. What 2 numbers can x be between.
Debora [2.8K]
The triangle inequality applies.

a) 10000 < 1000 +10x
.. 1000 < 100 +x
.. 900 < x

b) 1000 < 10000 +10x
.. 100 < 1000 +x
.. -900 < x

c) 10x < 10000 +1000
.. x < 1100

x can be between 900 and 1100

The radius of a circle is decreasing at a rate of 6.56.56, point, 5 meters per minute. At a certain instant, the radius is 12121
Ilia_Sergeevich [38]

Answer:

The rate of change of the area of the circle is  approximately -490.09 \ m^2/min.

Step-by-step explanation:

Given:

\frac{dr}{dt} = -6.5 \ m/min

radius r =12 \ m

We need to find the rate of change of the area of the circle at that instant.

Solution:

Now we know that;

Area of the circle is given by π times square of the radius.

framing in equation form we get;

A= \pi r^2

to find the rate of change of the area of the circle at that instant we need to take the derivative on both side.

\frac{dA}{dt}=\frac{d(\pi r^2)}{dt}\\\\\frac{dA}{dt}= 2\pi r \frac{dr}{dt}

Substituting the given values we get;

\frac{dA}{dt}= 2\times \pi \times 12 \times -6.5\\\\\frac{dA}{dt}\approx -490.09 \ m^2/min

Hence The rate of change of the area of the circle is  approximately -490.09 \ m^2/min.
