Answer:

y = 16.84

Step-by-step explanation:

y - 7.74 = 9.1

=> y = 9.1 + 7.74

=> y = 16.84

answer:

x = 4[tex]\sqrt{2}[/tex] or 5.6568

step-by-step explanation:

formula: a^2 + b^2 = c^2

a^2 + b^2 = c^2

7^2 + b^2 = 9^2

49 + b^2 = 81

b^2 = 32

b = 4[tex]\sqrt{2}[/tex]

x = 4[tex]\sqrt{2}[/tex] or 5.6568 (exact value)

Answer:

25 mg. is lighter than 25 cg.

Step-by-step explanation:

Well,

The prefix "milli" means thousandth and the prefix "centi" means hundredth.  So a milligram will be one-tenth of a centigram.

10 mg. = 1 cg.

25 mg. = 2.5 cg.

2.5 cg. < 25 cg.

25 mg. is lighter than 25 cg.

Answer:

25 milligrams are lighter, because 1 milligram equivales to 1 gram multiplied by 100.

Answer:

AB=5.39 cm

BC=5 cm

CD=5.83 cm

DE=3.91 cm

A to E=20.13 cm

Step-by-step explanation:

DE^2=2.5^2+3^2

DE^2=6.25+9

DE^2=15.25

DE=3.91

CD^2=3^2+5^2

CD^2=9+25

CD^2=34

CD= 5.83

BC^2=4^2+3^2

BC^2=16+9

BC^2=25

BC=5

AB^2=5^2+2^2

AB^2=25+4

AB^2=29

AB=5.39

5.39+5+5.83+3.91=20.13

Answer:

  √65 ≈ 8.06

Step-by-step explanation:

The distance formula is used for the purpose.

  d = √((x2 -x1)² +(y2 -y1)²)

  d = √((2 -(-5))² +(0 -4)²) = √(7² +(-4)²) = √(49 +16)

  d = √65 ≈ 8.0622577

The distance between C and Q is √65, about 8.06 units.

Answer:

84

Step-by-step explanation:

To complete the concrete highway with pavers 84 pavers are needed.

We know the perimeter of any 2D figure is the sum of the lengths of all the sides except the circle and the area of a rectangle is the product of its length and width.

From the given information each Pavel has an area of 4.5 square feet.

And the area of the driveway can be obtained by multiplying the length and width of the driveway which is,

= (21×18) sq feet.

= 378 sq feet.

Therefore, The number of pavers needed is,

= (378/4.5).

= 84 pavers.

Answer:

Step-by-step explanation:

If the slope is 1/5, we can interpret this as rise/run = 1/5.  We could (if we wished to do so) find the hypotenuse by using the Pythagorean Theorem:

hypo = +sqrt( 1^2 + 5^2)

In this case we dilate the triangle defined by the slope 1/5:  

2/10,        1/10/(1/2),           10/50,        etc.,       all represent right triangles whose hypotenuses lie on the same line (the line with slope 1/5).

The two right triangles are shown in the graph

The coordinates in rectangular cartesian system are of the form -

(x, y)

where -

{x} - distance along x - axis.

{y} - distance along y - axis.

Given is the slope of the line as - {m} = 1/5.

Refer to the graph attached. The line -

y = (1/5)x

is plotted. It can be seen that (0, 0) and (10, 2) lie on the line.  For two right triangles to lie on the same line, draw two perpendiculars from point (10, 2) along the {x} axis and {y} axis. Refer to the triangles shown in the graph.

Therefore, two right triangles are shown in the graph.
