Step-by-step explanation:

Answer: 2²/₃ pounds

Step-by-step explanation:

There are 8 pounds of fruit.

These are to be used to make 3 equal sized fruit salad.

The weights of each fruit salad will therefore be:

= Pounds of fruit/ Number of fruit salads

= 8 / 3

= 2²/₃ pounds

Given:

Point (7,12) is rotated 1260° counterclockwise about the origin.

To find:

The  x-coordinate of the point after this rotation.

Solution:

If a point is rotated 360 degrees then its coordinates remains unchanged.

If a point is rotated 180 counterclockwise about the origin degrees, then

[tex](x,y)\to (-x,-y)[/tex]

We know that,

[tex]1260^\circ=1080^\circ+180^\circ[/tex]

[tex]1260^\circ=3\times 360^\circ+180^\circ[/tex]

After [tex]3\times 360^\circ[/tex] rotation the coordinates of points remains same, i.e., (7,12). So, after that (7,12) is rotated 180° counterclockwise about the origin.

[tex](7,12)\to (-7,-12)[/tex]

The point (7,12) becomes (-7,-12) after rotation of  1260° counterclockwise about the origin.

Therefore, the x-coordinate of the required point is -7.

Answer: 65100 Calories

Step-by-step explanation:

Let's believe that there are 31 days in a month. Therefore, the number of days in 6 months will be:

= 31 × 6

= 186 days.

This means that the person will walk for 186 hours

The number of calories that will be burn will then be:

= 186 × 350

= 65100 calories

Answer:

$50 and $6

Step-by-step explanation:

(x-6)(250-5x)=0

250x - [tex]5x^{2}[/tex] - 1500 + 30x = 0

-5x^2 + 280x - 1500 = 0

(divide everything by -5)

x^2 -56x + 300 = 0

(factorise)

(x-50)(x-6)=0

x=50, x=6

Answer: x=60

Step-by-step explanation:

Hey! X would be 60 because the diagram on the left has proportions of 6/6. The diagram on the right has a porportion of x/60.  We want the proportions to be equal so it has to be 60!

6/6 = 1

60/60 = 1 (they are now equal and have equal proportions!)

Answer:

Output value = 20

Step-by-step explanation:

Graph of any function is made up of two values → Values on x axis and Values along y axis.

x values represent the input values and y values represents the output values.

For every x value there is a y value because of which the data set is called to a function.

In other words, a function can't have two output values for a single input value.

If the input value of function is = 10

Then for x = 10, out value (along y axis) will be = 20

Therefore, Output value of the given function is 20.

Step-by-step explanation:

Hi there!

Step By Step:

We know that 215 pounds are about 215 strawberries since every strawberry are about 1 pound.

Let think about this... 215 pounds are 215 strawberries.

If his brother ate 56 of the strawberries, it means that his brother ate 56 pounds of the strawberry.

We can also think like this... 56/215

Final Result: 56 pound sof strawberries.
