Complement of 50° = 40°

Supplement of 145° = 35°

Complement of 27° = 63°

Supplement of 50° = 130°

Step-by-step explanation:

Complementary angles add up to 90°

Supplementary angles add up to 180°

90° - 50° = 40°

180° - 145° = 35°

90° - 27° = 63°

180° - 50° = 130°

Answer:

Complement 50° = 40°

Supplement 145° = 35°

Complement 27° = 63°

Supplement 50° = 130°

Complement angles = adds up to 90°

Supplement angles = adds up to 180°

complete the equation 0.07( x+____) = 3,290
Sandras salary in the previous year was _____

Answers

9514 1404 393

Answer:

2,000$45,000

Step-by-step explanation:

Where x represents the previous year's salary, its amount this year is said to be ...

  x + 2000

The equation is trying to reflect the fact that 7% of that is $3,290. The missing number is 2000:

  0.07(x +2000) = 3290

__

Solving for x, we find ...

  x = (3290/0.07) -2000 = 45000

Sandra's salary the previous year was $45,000.

On which number line do the points represent negative seven and one over two and +1? (4 points)

Answers

Answer:

A number line is used in the mathematical positioning of real numbers that include the numbers from positive infinity to negative infinity. This includes rational, irrational, fractions, and whole numbers. In this case, we are given with an expression that we have to reduce to lowest terms: negative seven and one over two and +1. The first one is equal to -7.5 while the other one is equal to +1. Positive numbers lie on the right side of zero (center of the line) while negative numbers lie on the left on the other hand. -7.5 lies between -8 and -7 while +1 lies exactly between 0 and 2. Both of which are positive numbers.

The equation of the graph of [tex]f(x) = (\frac{3}{2})^{-x}[/tex] is graph (b)

The equation of the graph is represented as:

[tex]f(x) = (\frac{3}{2})^{-x}[/tex]

See attachment for the graph of [tex]f(x) = (\frac{3}{2})^{-x}[/tex]

From the attached graph, the curve passes through points (0,1) and (2,0.5).

4. Find the area of the
shaded region.

Answers

Diameter of the circle in the middle = 8 ft

Radius of the circle in the middle :

[tex] =\tt \: \frac{Diameter }{2} [/tex]

[tex] =\tt \frac{8}{2} [/tex]

[tex] =\tt 4 \: ft[/tex]

Thus, the radius of the circle in the middle = 4 ft

Area of the entire circle :

[tex] =\tt \pi {r}^{2} [/tex]

[tex] = \tt3.14 \times 4 + 6 \times 4 + 6[/tex]

[tex] = \tt3.14 \times 10 \times 10[/tex]

[tex] =\tt 3.14 \times 100[/tex]

[tex]\color{plum} = \tt314 \: ft[/tex]

Thus, the area of the entire circle = 314 ft

Area of the circle in the middle :

[tex] =\tt \pi {r}^{2} [/tex]

[tex] =\tt 3.14 \times 4 \times 4[/tex]

[tex] = \tt3.14 \times 16[/tex]

[tex]\color{plum} =\tt 50.24 \: ft[/tex]

Thus, the area of the circle in the middle = 50.24 ft

Area of the shaded portion :

= Total area of the figure - Area of the circle in middle

[tex] =\tt 314 - 50.24[/tex]

[tex]\color{plum} =\tt 263.76 \: ft[/tex]

▪︎Therefore, the area of the shaded portion = 263.76 ft

How far is the portion of her route from A to D? Round to the nearest whole number. Explain. I NEED IT BY TONIGHT SO PLSS SOMEONE HELP ME!

Answers

9514 1404 393

Answer:

  A to D is about 2087 ft

Step-by-step explanation:

For the portion of the path of interest, the sine and cosine relations apply.

  Sin = Opposite/Hypotenuse

  Cos = Adjacent/Hypotenuse

__

AB is the adjacent side to the angle marked 33°, with hypotenuse 975 ft.

  cos(33°) = AB/(975 ft)

  AB = (975 ft)cos(33°) ≈ 817.70 ft

BC is the opposite side in the same triangle.

  sin(33°) = BC/(975 ft)

  BC = (975 ft)sin(33°) ≈ 531.02 ft

CD is the hypotenuse of the right triangle BCD. The side BC that we know is opposite the given angle, so the sine relation applies.

  sin(46°) = BC/CD

  CD = BC/sin(46°)

  CD = (531.02 ft)/sin(46°) ≈ 738.21 ft

__

Now we know the segments of the path of interest:

  A–D = AB +BC +CD

  A–D = 817.70 ft + 531.02 ft + 738.21 ft = 2086.93 ft

  A–D ≈ 2087 ft

_____

Additional comments

The attachment shows all of the segments computed working counterclockwise from A. The angles in triangle DEF are computed using the Law of Sines from sides DF and DE and angle DEF. Segments EG and GH are computed using the Law of Cosines.

When we get to points F, G, H, we find that there is some inconsistency with the locations that would be computed working clockwise using AB and angle BFA. This inconsistency shows up in an error in the 119° angle in the attached figure.

This means that segments on the back side of the route, along path EFGHA, will vary somewhat depending on how they're computed.

We assume that points B, C, F, G are collinear.

The measures of the angles of a triangle are shown in the figure below.Solve for X
