Please can anyone solve 9n-10=4n+10

Answers

Answer 1

Answer: yes

remember you can do anything to an equaiton as long as you do it to boh sides
ad try to get unknown to one side
9n-10=4n+10
minus 4n both sides
9n-4n-10=4n-4n+10
5n-10=0+10
add 10
5n+10-10=0+10+10
5n+0=20
5n=20
divide both sies by 5
5n/5=20/5
5/5n=4
1n=4
n=4

Answer 2

Answer: 9n-10=4n+10
+10 +10
9n=4n+20
-4n -4n
5n =20
/5 /5
n=4

What is 2.33 written as a mixed number in simplest form?A. 1002/33
B. 233/100
C. 2100/33
D. 233/100

Answers

The correct answer for the question that is being presented above is this one: "233/100". When the decimal 2.33 written as a mixed number in simplest form, then the answer will 233/100. You just move the decimal point in 2.33 two places to the right. Since, there are two decimal places, therefore the denominator should be 100.

D.

Domain: {3, 1, –2, 9, 4}; Range: {5, 7, 11, 4, –2}

Answers

Answer is C. Set of first part of the binary set is domain and second part of it is range. So the domain will be {5, 7, 11, 4, –2} and the range will be {3, 1, –2, 9, 4}

Answer:

Domain: {5, 7, 11, 4, –2}; Range: {3, 1, –2, 9, 4}

Step-by-step explanation:

The domain is the X value or the independent in put.

Range is the Y values, or the Dependant input.

For a spinning amusement park ride, the velocity v in meters per second of a car moving around a curve with a radius r meters is given by the formula v=sqrt(ar), where 'a' is the car’s acceleration in m/s^2.a) For safety reasons, a ride has a minimum acceleration of 39.2m/s^2 . If the cars on the ride have a velocity of 14m/s what is the smallest radius that any curve on the ride may have?

b) What is the acceleration of a car moving at 8m/s around a curve with a radius of 2.5m?

Answers

The smallest radius will be, r = 5 m. And the acceleration of a car is, a = 25.6 m/s².

What is acceleration?

Acceleration is the ratio of the change of the velocity with respect to time or the rate of change of the velocity.

a.The relation between the velocity, the radius of the path, and the acceleration on the circular path is given by :

Acceleration, a = 39.2 m/s²

Velocity of the car, v = 14 m/s

The radius of the path can be calculated using the above formula i.e.

$r=(v^2)/(a)$

$r=((14)^2)/(39.2)$

r = 5 m

b. Velocity of the car, v = 8 m/s

The radius of the path, r = 2.5 m

The acceleration of the car is given by :

$a=(8^2)/(2.5)$

a = 25.6 square meter.

Therefore, the smallest radius will be, r = 5 m. And the acceleration of a car is, a = 25.6 m/s².

a)
v=sqrt(ar)
v^2=ar
r=(v^2)/a
r=(14^2)/39.2
r=5

5 m

b)
v=sqrt(ar)
v^2=ar
a=(v^2)/r
a=(8^2)/2.5
a=25.6

What the solution set (x+9)^2=169 of this quadratic equations by extracting the roots?

Answers

Answer:

x = - 22, x = 4

Step-by-step explanation:

Given

(x + 9)² = 169 ( take the square root of both sides )

x + 9 = ± $√(169)$ = ± 13 ( subtract 9 from both sides )

x = - 9 ± 13

Thus

x = - 9 - 13 = - 22

x = - 9 + 13 = 4
