Answer 1

Answer:

800

Step-by-step explanation:

the tenth is the second 9 and the 9 before it makes it round up

Thus, the second 9 rounds up also

Therefore, it changes the 7 to a 8 and the 9s are now 0s

How do you solve this 4x-2+x= -2+2x

Answers

Answer:

0

Step-by-step explanation:

First of all, simplify the equation on both sides. You will get 5x - 2 = 2x - 2. Add two to both sides, and you get 5x=2x. Subtract 2x from both sides to get 3x=0, so x will equal 0.

Answer:

5x = 2x

Step-by-step explanation:

5x- 2 = 2 + 2x

5x - 2+ 2 = -2 + 2x +2

Which of the following represents the factorization of the binomial below?
x² - 144
A. (x+12)(x-12)
B. (x-12)(x-12)
C. (x+12)(x +12) D. (X)(x-144)

Answers

Answer:

A. (x+12)(x-12)

Step-by-step explanation:

Use foil method

x * x = x^2

x * - 12 = - 12x

12 * x = 12 x

12 * - 12 = - 144

x^2 [- 12x + 12x= 0x = 0] - 144

x^2 + 0 - 144 =

x^2 - 144 #

f(x) = 9 - x, g(x) = x2 + x, h(x) = x - 2
Compute the following:
f(g(4)

Answers

Answer:

f(g(4) = -11

Step-by-step explanation:

Whenever we are given a composite function where the output of one of the functions serves as an input for the second one, the first step is to evaluate the numerical output from the first function.

Output from first function: g(x) = [tex]x^{2} + x[/tex]

g(4) will be evaluated by substitution 4 for x in the above equation.

this will give us [tex]g(x)=4^{2}+4 =20[/tex]

Output from the composite function f(g(4)

The next stage is to input our results from the function g(4) into the function

f(x) = 9 - x. The output from g(4) which is 20, will now become our input.

[tex]f(x)-9-(20)= -11[/tex]

Therefore f(g(4) = -11

Three sides of a pentagon have a length of 26 cm each. Each of the remaining two sides has a length of 14.5 cm. What is the perimeter of the pentagon? 75 cm 81 cm 107 cm 377 cm

Answers

Answer:

107 cm

aaaaaaa

aaaaaaa

Answer:

107 cm

Step-by-step explanation:

To find this you just first add the 26cm three times because thats the length of 3 sides and you get 78 then you multiply 14.5 times 2 for the other two sides that length and you get 29. Next you add 78+29 and you get 107cm

Answer: (a) ([tex]x_{2},y_{2}[/tex]) = (3,2)

              (b)  ([tex]x_{2},y_{2}[/tex]) = (19,-7)

Step-by-step explanation: Midpoint of a segment is halfway between 2 endpoints. It is calculated using the formulas:

[tex]x_{m}=\frac{x_{1}+x_{2}}{2}[/tex]

[tex]y_{m}=\frac{y_{1}+y_{2}}{2}[/tex]

Isolating [tex]x_{2}[/tex]:

[tex]x_{2}=2x_{m}-x_{1}[/tex]

And [tex]y_{2}[/tex]:

[tex]y_{2}=2y_{m}-y_{1}[/tex]

(a) Replacing values and calculating [tex]x_{2}[/tex]:

If one kilogram equals 2.2 pounds, how many kilograms equal 112 pounds? Round your answer to the nearest hundredth, if necessary. 24.64 kilograms 50.91 kilograms 109.8 kilograms 246.4 kilograms

Answers

Answer:

B.) 50.91 kilograms

Step-by-step explanation:

Write an equation that looks like this:

[tex]\frac{kilogram}{pound}= \frac{kilogram}{pound}[/tex]

Insert the information in the appropriate section, with 1 kilogram and 2.2 pounds on the same side:

[tex]\frac{1}{2.2}=\frac{x}{112}[/tex]

Solve for x, which is the number of kilograms for 112 pounds if there is 1 kilogram per 2.2 pounds.

Solve for x. Cross multiply:

[tex]1(112)=2.2(x)\\\\112=2.2x[/tex]

Isolate the variable. Divide both sides by 2.2:

[tex]\frac{112}{2.2}=\frac{2.2x}{2.2}\\\\x= 50.909090...[/tex]

Round to the nearest hundredth (two decimal places to the right):

50.909 → 50.91

If 1 kilogram is equal to 2.2 pounds, then 50.91 kilograms is equal to 112 pounds.

b bc the oter guy is alomost as smort as walter

Step-by-step explanation:

A car, initially at rest, travels 20 m in 4 s along a straight line with constant acceleration. The acceleration of the car is: 1. 0.4 m/s 2 2. 9.8 m/s 2 3. 4.9 m/s 2 4. 1.3 m/s 2 5. 2.5 m/s 2

Answers

Answer:

2.5m/s²

Step-by-step explanation:

Using the equation of motion S = ut + 1/2at² where;

S is the distance travelled = 20m

u is the initial velocity = 0m/s (car starts from rest)

a is the acceleration = ?

t is the time taken = 4s

To get the acceleration of the car, we will substitute the given parameters into the given equation.

S = ut + 1/2at²

20 = 0(4)+1/2a(4)²

20 = 0+ a/2*16

20 = 8a

divide both sides by 8

20/8 = 8a/8

20/8 = a

a = 20/8

a = 2.5m/s²

Hence the acceleration of the car is 2.5m/s²
