2/5 of the 45 oranges fell out of the tree. how many oranges fell out of the tree?

Answers

Answer:

18 oranges

Step-by-step explanation:

To find this, we have to calculate 2/5 * 45, which is equal to 45 * 2 and then divided by 5 (Or you could cross cancel). 45 * 2 is equal to 90 and 90/5 is equal to 18. That means that 18 oranges fell out of the tree.

The drawing below represents a 22-foot ladder with its base placed 10 feet from the bottom of a vertical wall. whatis the best value for x

Answers

Answer:

x = 62.96°

Step-by-step explanation:

From the attached figure,

Base, b = 10 ft

Hypotenuse, H = 22 ft

We need to find the value of x. We can use trigonometry to find it.

We know that,

[tex]\cos\theta=\dfrac{B}{H}[/tex]

Putting all the values,

[tex]\cos x=\dfrac{10}{22}\\\\x=62.96^{\circ}[/tex]

So, the value of x is 62.96°.

The area of this rectangle is 10cm2, find the value of x and use it to find the length and the width of the rectangle.
If the length of a rectangle is three time the width and it’s perimeter is 24 cm, what is its area?

Answers

Answer:

The area of this rectangle is 10cm2, find the value of x and use it to find the length and the width of the rectangle.

If the length of a rectangle is three time the width and it’s perimeter is 24 cm, what is its area?

Length and width of the rectangle are 4 cm and 2.5 cm respectively.

Given in the picture,

A rectangle with the area of 10 cm².Expressions representing the lengths of the rectangle as

        (4x + 2) cm and (10x - 1) cm

By the property of a rectangle, measure of opposite sides of a rectangle are always equal,

(4x + 2) = (10x - 1)

(4x + 2) - 4x = (10x - 1) - 4x

2 = 6x - 1

2 + 1 = (6x - 1) + 1

3 = 6x

[tex]x=\frac{3}{6}=\frac{1}{2}[/tex]

Now we can get the length of the given rectangle by substituting the value of 'x' in (10x - 1) or (4x + 2).

(10x - 1) = [tex]\frac{10}{2}-1[/tex]

            = 4 cm

Since, area of a rectangle is given by the expression,

Area = Length × width

By substituting the values in the expression,

10 = 4 × width

Width = [tex]\frac{10}{4}[/tex]

           = 2.5 cm

        Therefore, length and width of the rectangle are 4 cm and 2.5 cm respectively.

The ratio of the side lengths of a quadrilateral are 2:3:5:7. If the quadrilateral's perimeter is 68, what is the length of each side?

Answers

We should find the equivalent ratios of 2:3:5:7 and then add the numbers together to get a sum of 68. A unit rate of two: 4:6:10:14 = 24. A unit rate of three: 6:9:15:21 = 51. A unit rate of four: 8:12:20:28 = 68. Now we know that the length of each side is 8:12:20:28.

find the equation of the line that is parallel y= 2x+10 and passes through the point (6,-4)

Answers

Answer:

The equation of the parallel line to the given line

y = 2 x - 16

Step-by-step explanation:

Step(i):-

Given equation of the straight line y = 2 x +10

                                             2x - y + 10 =0

The equation of the parallel line to the given line is

           a x + by + k=0

The equation of the parallel line to the given line is

           2x - y + k=0

Step(ii):-

Given point ( 6,-4)

The equation of the parallel line to the given line is

           2x - y + k=0

This line passing through the point ( 6,-4)

           2(6) - (-4)+ k=0

          12 + 4 +k =0

           16 + k=0

                k = -16

Final answer:-

The equation of the parallel line to the given line

y = 2 x - 16
