What is the measure of arc GH??

Answers

Option C:

The measure of arc GH is 45°.

Solution:

Given data:

m∠GFH = 22.5°

To find the measure of arc GH:

By inscribed angle theorem,

The measure of an inscribed angle is equal to the half of the measure of the intercepted arc.

$$m\angle GFH = (1)/(2)* m \ {(arc \ GH)}$

$$ 22.5^\circ= (1)/(2)* m \ {(arc \ GH)}$

Multiply by 2 on both sides, we get

$$ 2* 22.5^\circ= 2* (1)/(2)* m \ {(arc \ GH)}$

$$ 45^\circ= m \ {(arc \ GH)}$

Switch the sides.

m(arc GH) = 45°

The measure of arc GH is 45°.

Kofi estimated that he would run a total of 10 km in 1 h. In 1 h, he actually ran 46 times around a track 0.25 km long, going a total distance of 11.5 km.What was the percent error in Kofi’s estimate? Round to the nearest tenth of a percent, if necessary.

A.
1.5%

B.
5%

C.
13%

D.
23%

Answers

The equation to find percent error is

$(actual-theoretical)/(theoretical)*100$

where actual is the value that actually came out (in this case, 11.5 km) and theoretical is the value that was supposed to come out (in this case, 10 km). Just plug in the numbers and simplify.

$(actual-theoretical)/(theoretical)*100\n\n(11.5-10)/(10)*100=(1.5)/(10)*100=15\%\ error$

So, the true answer would be 15%. Apparently, the question you're asking takes 11.5 as the theoretical and the 10 as the actual (which I personally disagree with)

If you plugged in the numbers that way, the answer comes out to 13.04%. So, the correct answer for your answer choices is c. 13%

A radio station spends 1/40 of each 24 hours on public service announcements. How much time is spent on public service announcements each day?

Answers

Answer: They spent 0.6 hours =36 minutes on public service announcements each day.

Step-by-step explanation:

Since we have given that

Number of hours in a day = 24 hours

Fraction of hour a radio station spends on public service announcements = $(1)/(40)$

So, Number of hours spent on public service announcements each day would be

$(1)/(40)* 24\n\n=(24)/(40)\n\n=0.6\ hours$

As we know that

1 hour = 60 minutes

0.6 hours = 0.6×60 = 36 minutes

Hence, they spent 0.6 hours = 36 minutes on public service announcements each day.

Start by calling the time spend on announcements 'A'. We can then set up an equation to represent the problem:

$A=24hours * (1)/(40)$

and then solve by multiplication to get:

A=0.6hours

We could also convert this into minutes:

$A=0.6hours * (60mins)/(1hour) = 36mins$

Order the quadratic functions from widest to narrowest graph. y=4x^2 y=2x^2 y= 0.15x^2

Answers

ANSWER

$y=0.15x^2, y=2x^2,y=4x^2$

EXPLANATION

The given quadratic functions are;

$y = 4 {x}^(2)$
$y = 2 {x}^(2)$
and

$y = 0.15 {x}^(2)$

A fractional coefficient indicates a horizontal stretch.

The smaller the coefficient, the wider the stretch for
$|a| < 1$
and

$a \ne0$

Also
$|a| > 1$
indicates a horizontal compression.

The higher the value the narrower the graph.

Therefore from widest to narrowest, we have,

$y=0.15x^2, y=2x^2,y=4x^2$

See graph.
