If it is said that the range of the answer should be +/- 10% of the particular value, we have to find out the percentage of that particular value. Therefore 10% of 1.8 is,

1.8 * 10/100 = 0.18

If we add this value to the original value,
1.8+0.18 = 1.98

If we subtract this value from the original value,
1.8-0.18 = 1.62

therefore the range will be,
from 1.62 to 1.98

Answer:

y = 2666.67

Step-by-step explanation:

Well to solve this we can make a system of equations.

x = cost of car alone

y = cost of accesories,

$\left \{ {{x+y=24000} \atop {x=8y}} \right.$

So now we plug in 8y for x in x + y = 24000.

(8y) + y = 24000

9y = 24000

Divide both sides by 9

y = 2666.666666

or 2666.67 rounded to the nearest hundredth.

Now that we have y we can plug that in for y in x=8y.

x = 8(2.666.67)

x = 21,333.33 rounded to the nearest hundredth.

Thus,

accessories "y" cost around 2666.67.

Hope this helps :)

Step-by-step explanation:

If you remember that Sin is opposite over hypotenuse then the opposite of angle A is 5 and the hypotenuse is 13 so it would equal 5/13.

Which statement is true? Question 5 options: All rectangles are squares. All quadrilaterals are rectangles. All squares are rect

lozanna [386]

Answer:

All squares are rectangles.

Step-by-step explanation:

The requirements for a shape to be qualified as a rectangle are that there must be four sides, two sets or parallel sides, and four right (90 degree) angles. The requirements for a square are that all sides must be equal in length and that there must be four right angles. Since the requirements of a square fit under those of a rectangle, all squares are rectangles.

Help answer please!!

12345 [234]

Answer:

h = 19.7 ft.

Step-by-step explanation:

Use the Pythagoras Theorem

$(Hypotenuse)^2 = (Base)^2 + (Perpendicular)^2\\\\(20)^2=(3.5)^2+(h)^2\\400=12.25+h^2\\400-12.25=h^2\\387.75=h^2\\$

Now we take square root on both sides,

$\sqrt{387.75} =\sqrt{h^2}\\19.69=h\\h=19.7\ ft\\$

so the value of h equals 19.7 ft.
