An angle measures 125.2° more than the measure of its supplementary angle. What is the measure of each angle?

Answers

Answer:

27.4 and 152.6

Step-by-step explanation:

Supplementary angles equal 180 degrees when placed together.

x+(x+125.2)=180

2x+125.2=180

A thin wire 40 CM long is formed into a rectangle if the width of this rectangle is 8 CM what is length and area

Answers

Given:

Length of a wire = 40 cm.

Breadth of the rectangle formed = 8 cm.

Find:

length and area of rectangle.

Solution:

Length of a wire = 40 cm.

A rectangle is made from this wire.

That means,

Perimeter of the rectangle formed = length of the wire.

Also,

Breadth of the rectangle formed = 8 cm.

We know that,

Perimeter of a rectangle = 2(length + breadth).

Let the length of the rectangle be x cm.

Hence,

→ 2(x + 8) = 40

→ 2x + 16 = 40

→ 2x = 40 - 16

→ 2x = 24

→ x = 24/2

→ x = 12

Hence,

Length of the rectangle formed = x = 12 cm.

Now,

We know,

Area of a rectangle =length * breadth

→ Area of the rectangle = (12) * (8)

→ Area of the rectangle = 96 cm²

Therefore, the area of the rectangle formed is 96 cm².

I hope it will help you.

If -4 is a solution of the equation f(x) = 2, which must be the coordinates of a point on the graph of f?
(4,-2)
0 (-2,4)
O (2,-4)
O (-4, 2)

Answers

the answer is (-2,4) (:

The coordinates of the point on the graph of is (-4,2).

What is a function?

A function is defined as the relationship between input and output, where each input has exactly one output. The inputs are the elements in the domain and the outputs are elements in the co-domain.

If -4 is a solution of the equation f(x) = 2,

When giving the input as  -4 the output will be 2.

Thus these can be written in ordered pair as (-4,2).

Hence, the coordinates of the point on the graph of is (-4,2).

Diana is comparing the membership costs at two fitness centers. The community fitness center costs $60 per month. The fitness center located where she works has a $100 registration fee and costs $40 per month. After how many months of membership will the costs be the same? 2 3 4 5

Answers

Answer:

The indifference point is 5 months.

Step-by-step explanation:

First, we need to structure the total cost formula for each fitness center:

Community center= 60x

Work center= 100 + 40x

x= number of months

Now, we equal the formulas and isolate x:

60x = 100 + 40x

20x = 100

x= 5

The indifference point is 5 months.

A cat can travel a distance of 32.5 meters in 13 seconds. What is the average speed of the cat to the nearest hundredth of a m/s? *

A 2.5 mph

B 0.4 mph

C 2.5 m/s

D 0.4 m/s

Answers

Answer:

C. 2.5 m/s

Explanation:

Speed can be defined as distance covered per unit time. Speed is a scalar quantity and as such it has magnitude but no direction.

Mathematically, speed is given by the equation;

[tex]Speed = \frac{distance}{time}[/tex]

[tex]S = \frac{d}{t}[/tex]

Given the following data;

Distance = 32.5m

Time = 13secs

Substituting into the above equation;

[tex]S = \frac{32.5}{13}[/tex]

Speed, S = 2.5m/s

Write an equation and show your work: There were five different Foil Kites that each descend 50 feet per second for 5 seconds. Find the total change in altitude for all 5 kites.

Answers

Answer: Change in altitude = (50 x 5) feet

The total change in altitude for all 5 kites. = 250 feet

Step-by-step explanation:

Given : Rate of descent = 50 feet per second  (speed)

Time = 5 seconds

Since, distance = speed x time

Change in altitude = Rate of descent x Time

Change in altitude = 50 x 5 feet  [required equation]

= 250 feet

Hence, the total change in altitude for all 5 kites. = 250 feet
