What is 2.87 rounded to the nearst tenth

Answer: y = f (n 1)

Step-by-step explanation:

If we count interest rate = 5%

then if he earned 'y' amount in 1st year then in 2nd year he must earned

= y + 5% of y

== 1.05 y

here, y = f(n 1)

Answer:

D

Step-by-step explanation:

the sum of the 3 angles in Δ DEF = 180° , that is

∠ D + 90° + 35° = 180°

∠ D + 125° = 180° ( subtract 125° from both sides )

∠ D = 55°

------------------------

using the tangent and cosine ratios in the right triangle

tan35° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{DE}{EF}[/tex] = [tex]\frac{DE}{12}[/tex] ( multiply both sides by 12 )

12 × tan35° = DE , then

DE ≈ 8.40 ( to 2 dec. places )

--------------------------

cos35° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{EF}{DF}[/tex] = [tex]\frac{12}{DF}[/tex] ( multiply both sides by DF )

DF × cos35° = 12 ( divide both sides by cos35° )

DF = [tex]\frac{12}{cos35}[/tex] ≈ 14.65 ( to 2 dec. places )

Answer:

16/5

Step-by-step explanation:

The direct variation equation (where k is the constant variation):

z = kw

First, we must solve for k:

k = w/z

Plug in -5 and 2:

k = 2/-5 = -2/5

Now plug k into the formula with 8 to solve for z:

z = -2/5 x 8 = 16/5

California is the most populated state, New York is the least populated, and 26% of Americans live in California, New York, and Texas.

Convert all statistics to percentages:

CA: 3 25 = 0.12 or 12%, 0.12 100 to calculate percentages.

NY: 3 50 = 0.06, or 6%, and 0.06 100 to get the percentage.

TX: 2 25 = 0.08 = 8%, 0.08 100 = percent

(A) California has the largest population of the three states.

(B) New York has the smallest population of the three states.

(C) USA = 100%, CA + NY + TX = 26%, so 74% of Americans do not live in these three states.

Price of key ring = £1.6

Price of purse = £3.2

The unitary approach is a strategy for problem-solving that involves first identifying the value of a single unit, then multiplying that value to figure out the required value.

Given Data

Vicky makes 8 purses and 9 key rings to sell for charity.

Vicky wants to get a total of exactly £40

Suppose the price of key ring be v

and the price of purses be 2v

£40 = £8(2v) + £9(v)

40 = 16v + 9v

40 = 25v

v = [tex]\frac{40}{25}[/tex]

v = 1.6

The numerical length of GH = 20 units

FH is a line segment.

G is a point on the line segment.

Then G divides the line segment FH into two line segments FG and GH.

We are given the lengths of FH, FG and GH in terms of x.

That is,  FH=4x+8, FG=x and GH=5x

We need to find the numerical length of the line segment GH. We first need to find the x for this.

As G cuts the line segment FH into two parts, the length of the line segment FH is the sum of the lengths of the line segments FG and GH.

That is, FH = FG + GH

⇒ 4x+8 = x +5x

⇒ 4x+8 = 6x

⇒ 2x = 8

⇒ x = 4

So the numerical length of GH = 5x = 5 x 4 = 20 units

Yw

Answer:

1.34 units.

Step-by-step explanation:

The line y = 2x - 5 has a slope of 2 so the line passing through the given point will be perpendicular to y= 2x - 5 and will have a slope of -1/2.

Let this line be y = -1/2x + c.

Its passes through (4, 6) so:

6 = -1/2*4 + c

6 = -2 + c

c = 6 + 2 = 8

So, equation of this line is y = -1/2x + 8.

Now we find the point where the 2 lines intersect:

y = 2x - 5

y = -1/2x + 8

2x - 5 = -1/2x + 8

2x + 1/2 x = 5 + 8

(5/2)x = 13

x = 26/5

  = 5.2.

and y = 2(5.2) - 5

          = 5.4.

So, the point of intersection is (5.2, 5.4)

and the distance between the point (4,6) and the line y = 2x - 5

= √((6 - 5.4)^2 + (4-5.2)^2)

= √(0.36 + 1.44)

= √1.8

= 1.34

Answer:

x=22

Step-by-step explanation:

Since a straight line is equal to 180 degrees,

(3x+3)+(5x+1) = 180

(3x+3)+(5x+1)-180=0

8x+4-180=0

8x-176=0

8x=176

x=176/8

x=22

Which also means that the first angle is (3(22)+3)=69 degrees

the second angle is (5(22)+1) = 111 degrees

111 + 69 = 180

The given coordinate pair, (10, -7) is not on the x–axis or the y–axis, but it is in Quadrant IV

A coordinate pair specifies a point on the coordinate plane.

The coordinates of points on the x–axis have a y–coordinate of 0

Therefore, the coordinates of a point that is on the x–axis can be expressed as (x, 0)

Points that are on the y–axis have a x–coordinate of 0, which gives the coordinates of the points located on the y–axis as (0, y)

The coordinates of the given point is (10, -7), therefore, the point is neither on the x or y–axis, but in one of the four quadrants.

The coordinate of points in the first quadrant can be represented generally as (x, y)

Points in the second quadrant have the general form of (-x, y)

The points in the third quadrant can be expressed generally in the form (-x, -y)

The coordinates of points on the fourth quadrant are of the form, (x, -y)

The given point is (10, -7), therefore it is in the fourth quadrant or Quadrant IV
