Answer:

the answer would be 70/100 in fraction form, 70% in percent, and (i believe) 0.7 min decimal form. Hope this helps!

Answer:

70 out of 100 is the ratio 70 Over 100 apostrophe , so it represents 70%. 70 Over 100 can be reduced by dividing the numerator and the denominator by 10 to get the reduced fraction 7 Over 10. Dividing 7 by 10 results in the decimal equivalent 0.70.

The speed of a motorcycle increases from 10km/hr to 50km/hr in 9 seconds. What is its acceleration?

ivanzaharov [21]

Acceleration of motorcycle= 1.23m/s^2

Step-by-step explanation:

We need to find the acceleration of motorcycle When its speed increases from 10km/hr to 50km/hr in 9 seconds

Given:

Initial speed= 10km/hr

Final speed= 50km/hr

Time = 9 seconds

Acceleration = ?

Formula: $Acceleration =\frac{Change\,\,in\,\,velocity}{time}$

Solution:

We will first convert the speed from km/hr to m/s

Converting Initial speed 10km/hr into m/s

1 km = 1000 m

10 km = 10,000 m

and 1 hr = 3600 s

So, Initial speed = 10,000/3600 = 2.77 m/s

Converting Final speed 50km/hr into m/s

1 km = 1000 m

50 km = 50,000 m

and 1 hr = 3600 s

So, Initial speed = 50,000/3600 = 13.88 m/s

Now Using formula of acceleration:

$Acceleration =\frac{Change\,\,in\,\,velocity}{time}\\Change\,\,in\,\,velocity =Final\,\,speed-Initial\,\,speed\\Change\,\,in\,\,velocity=13.88 - 2.77\\Change\,\,in\,\,velocity = 11.11 m/s\\Acceleration =\frac{11.11}{9}\\Acceleration =1.23 m/s^2$

So, Acceleration of motorcycle = 1.23m/s^2

Hellp me solve this thanks

Answer:

c. 10 cm

Step-by-step explanation:

The parallel sides of trapizium are the bases so

base 1(B1) =9cm , base(B2)= 12cm

$area(a) = 105 {cm}^{2}$

the perpendicular distance means the height so lets find the height

area of trapizium= B1 + B2 × h

2

${105cm}^{2}(the \: given \: area) = \frac{9cm(the \: given \: base) + 12cm(the \: given \: base)}{2} \times h$

${105cm}^{2} = \frac{21cm}{2} \times h$

now we crisscross

${105cm}^{2} \times 2 = 21cm \times h$

${210cm}^{2} = 21cm \times h$

$\frac{ {210cm}^{2} }{21cm} = \frac{21cm \: }{21cm} \times h$

h = 10 cm

hope u like it ‍❤️‍‍❤️‍‍❤️‍

$\text{Hello There!}$

$\text{You are adding and subtracting for this equation.}$

$\text{$500-160=340}$

$\text{Since 340 is a factor of 20}$

$\text{You add +20 until you get 340.}$

$\text{20}\times{17=340}$

$\text{So your answer is going to be}$

$\huge\text{17}$

Answer:

Step-by-step explanation: Because for inverse functions, domain and range of functions exchange. In simple words, domain of function h(x) = range of inverse function & range of function h(x) = domain of inverse function.
