Answer:
9000
Step-by-step explanation:
This is written in scientific notation. When you have a positive exponent (x³), You move the decimal point to the right as many times as the exponent says. Since the exponent is +3, move the decimal to the right 3 spaces:
[tex]9.0(0)\\\\90.0(1)\\\\900.0(2)\\\\9000.0(3)[/tex]
So:
[tex]9*10^3=9000[/tex]
:Done
*Magnifying means that the image will be bigger. So, the new number has to be greater than 9. Since 9000>9, this is true.

Answer:
[tex]x=120^o[/tex]
in order: 60, 60, 120, 120 (all of them in degrees)
Step-by-step explanation:
We need to add all four angles given (I'll use 0.5 instead of 1/2 to make the addition easier to type):
0.5 x + 0.5 x + x + x = 360
3 x = 360
x = 360/3 = 120
Therefore, [tex]x=120^o[/tex]
now the angles are:
two of them are 1/2 of x, that is: 120/2 = 60
Then smallest angles are: [tex]60^o \,\,\,and \,\,\,60^o[/tex]
the largest are directly equal to "x", that is: [tex]120^o\,\,\,and \,\,\,120^o[/tex]
Solve the following equation by using inverse operations to find the value of x. Hint: The sum of all interior angles in a triangle is 180 degrees.
x=60
x=90
x=30
x=180
Answer:
[tex] x = 30 [/tex]
Step-by-step explanation:
Given [tex] 2x, 3x, x [/tex], as the interior angles of the ∆, since sum of interior angles of ∆ = 180°, equation to solve for the value of x is given as:
[tex] 2x + 3x + x = 180 [/tex]
Combine like terms
[tex] 6x = 180 [/tex]
Apply the inverse operation of multiplication to solve for x. Since 6 is multiplying x = 6x, to get the value of x, the inverse operation of multiplication is division. Therefore, we would divide each side of the equation by 6.
[tex] \frac{6x}{6} = \frac{180}{6} [/tex]
[tex] x = 30 [/tex]
the sum of 18 and a number x is equal to 22
Answer:
x=4
Step-by-step explanation:
the sum of 18 and a number x
that's just 18+x
is equal to 22
that means that something=22
=22
put all together
[tex]18+x=22\\\\18-18+x=22-18\\\\x=4[/tex]
The required value of x is 4.
Assume that the number we're looking for is represented by 'x'. According to the problem,
The sum of 18 and x is equal to 22.
We can write this as an equation: 18 + x = 22.
To solve for x,
Isolate it on one side of the equation.
We can do this by subtracting 18 from both sides:
18 + x - 18 = 22 - 18.
This simplifies to,
x = 4.
Therefore, the value of x that satisfies the equation is 4.

jar contains pink and green marbles in the ratio 3 : 4. When John replaces 5 of the green marbles with 8 pink marbles, the ratio becomes 29 : 23. The ratio of the total number of marbles in the jar after replacement to the total number of marbles in the jar originally is : .
Answer:
52:49
Step-by-step explanation:
pink:green
The ratio of pink to green marbles is
3k:4k
He removes 5 green marbles and adds 8 pink marbles.
Now the ratio of pink to green marbles is
(3k + 8):(4k - 5)
This rario is equal to 29:23.
(3k + 8)/(4k - 5) = 29/23
29(4k - 5) = 23(3k + 8)
116k - 145 = 69k + 184
47k = 329
k = 7
Original amounts:
3 * k = 3 * 7 = 21 pink
4 * k = 4 * 7 = 28 green
Original total = 21 + 28 = 49
Amounts after replacement:
3k + 8 = 3(7) + 8 = 29 pink
4k - 5 = 4(7) - 5 = 23 green
Total after replacement = 23 + 29 = 52
Answer: The ratio of the total number of marbles in the jar after replacement to the total number of marbles in the jar originally is 52:49.

Find the original price of a pair of shoes if the sale price is $84 after a 30% discount.
Answer:
Original price = $ 120Step-by-step explanation:
To find the original price given the new price and percentage discount we use the formula
[tex]original \: \: price = \frac{100}{(100 - x)} \times new \: \: price \\ [/tex]
where
x is the percentage discount
From the question
new price = $ 84
% discount = 30%
Substitute the values into the above formula and solve
That's
[tex]original \: \: price = \frac{100}{100 - 30} \times 84 \\ = \frac{100}{70} \times 84 \\ = \frac{10}{7} \times 84 \\ = 12 \times 10[/tex]
We have the final answer as
Original price = $ 120Hope this helps you

Answer:
[tex] \frac{3}{4} [/tex]
Step-by-step explanation:
Given:
Interval, [0, 4]
Required:
Average range of change over [0, 4]
SOLUTION:
Find f(0) and f(4) from the graph:
[tex] f(0) = 0 [/tex] (when x = 0, y = 0)
[tex] f(4) = 3 [/tex] (when x = 4, y = 3)

Maria worked 5.1 hours on Monday and 7.35 hours on Tuesday. She gets paid $9.20 an hour. How much, in dollars, did Maria earn this week
Answer:
$114.54
Step-by-step explanation:
In order to answer this question, we are going to have to do some multiplication :)
First, we will find out how much Maria got paid on Monday. In order to find this, we must multiply 5.1 hours by $9.20, so
5.1 * 9.20 = 46.92
We will be using this number a little later. Next, we have to find out how much Maria got paid on Tuesday, so we have to multiply 7.35 hours by $9.20, so
7.35 * 9.20 = 67.62
Now, we will combine the numbers:
67.62 + 46.92 = 114.54
Therefore, Maria earned $114.54 this week
Hope this helps :)
105.34 and you would first add the hours together so 5.1 + 7.35= 11.45 then you would multiple $9.20 X 11.45= 105.34

Simplify the numerical expression.
1 + 24 + ( + 3) = 1
The expression has a value equal to ???
Answer:
27
Step-by-step explanation:
Given expression :
1 + 24 + ( + 3) = 1
Bring the number 1 to the left side of the equal sign. The positive 1 becomes negative 1 when brought towards the left side of the equal sign.
1 + 24 + ( + 3) - 1 = 0
Now, opening the bracket, we get
1 + 24 + 3 - 1 = 0
Negative 1 and positive 1 will get cancel
24 + 3 = 0
or 27
Therefore, the value of the numerical expression 1 + 24 + ( + 3) = 1 is 27.

Raina has a fabric of area 7912 centimetre square find the largest square that can be cut from it how much piece will be left in any
Answer:
Kindly check explanation
Step-by-step explanation:
Given the question:
Raina has a fabric of area 7912 centimetre square find the largest square that can be cut from it how much piece will be left
Area of fabric = 7912 cm²
Largest square that can be cut from it :
Taking the square root of 7912
Sqrt(7912) = 88.94 cm
Hence, it can be deduced that the largest square tht can be cut from it will be 88cm
From area of a square = a²
Where area is the length of the side (since all sides are equal)
a² = 88² = 7744cm²
Hence, area left = (7912 - 7744) cm² = 168 cm²

The value of x is 1.4 when z = 4.0 and y = 5.6.
What are Arithmetic operations?Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions. The operator that performs the arithmetic operation is called the arithmetic operator.
Operators which let do a basic mathematical calculations.
+ Addition operation: Adds values on either side of the operator.
For example 12 + 2 = 14
- Subtraction operation: Subtracts the right-hand operand from the left-hand operand.
for example 12 -2 = 10
* Multiplication operation: Multiplies values on either side of the operator
For example 12*2 = 24
Given the equation as:
z = y/x
z = 4.0 and y = 5.6
To determine the value of x
⇒ z = y/x
Multiply by x on both sides
⇒ xz = y
Substitute the values z = 4.0 and y = 5.6
⇒ x(4) =(5.6)
Divide both sides by 4
⇒ x = (5.6)/(4)
⇒ x = 1.4
Hence, the value of x is 1.4 when z = 4.0 and y = 5.6.
