Answer: x = 29.
Step-by-step explanation: Step 1: Simplify both sides of the equation.
x−6=23
Step 2: Add 6 to both sides.
x−6+6=23+6
x=29

Answer:
234Step-by-step explanation:
surface area = 2( LW + LH + WH)
where L = Length = 9
W = Width = 2
H = Height = 9
plugin values into the formula:
surface area = 2 ( LW + LH + WH)
= 2 ( 9*2 + 9*9 + 2*9 )
= 2 ( 18 + 81 + 18 )
= 2 (117)

Vincent has already finished 5 oil changes today, and can complete more at a rate of 1 oil change per hour. Warren just came on shift, and can finish 2 oil changes every hour. Sometime during the day, the friends will be tied, with the same number of oil changes completed. How long will that take? How many oil changes will Vincent and Warren each have done?
Answer:
Oil changes = 5
Vincent = 10 oil changes
Warren = 10 oil changes
Step-by-step explanation:
Vincent = 5 + h
Warren = 2h
Where,
h = number of oil changes
How long will that take?
Vincent = Warren
5 + h = 2h
5 = 2h - h
5 = h
h = 5
Number of oil changes = 5
How many oil changes will Vincent and Warren each have done?
Vincent = 5 + h
= 5 + 5
= 10 oil changes
Warren = 2h
= 2(5)
= 10 oil changes

What is the first step in converting 139,000,000,000,000,000 to a scientific notation?
Move the decimal after the number 1.
O Move the decimal after the number 9.
O Drop all of the zeroes following the number 9.
O Count the number of positions to move the decimal place.
Answer:
i think it is Move the decimal after the number 1.
Step-by-step explanation:
it the text it says
"To convert our example, 602,200,000,000,000,000,000,000, into a scientific notation, the first step is to place a decimal after the digit 6, and then drop all the zeros after the 2. This will leave us with a coefficient of 6.022. Next, to find the exponent, count the number of times you had to move the decimal point until it landed after the first digit of the coefficient. The answer is 23; therefore, the scientific notation is 6.022 x 1023. In cases where the numbers are multiples of 10, only the base number 10 and the exponent can be used. For instance, the number 1,000,000,000, can be written as 109. Now you try it. What is the scientific notation for a light year, which has been estimated at 9,500,000,000,000 km? As you read the information in this lesson, challenge yourself by converting the large numbers into scientific notations."
Awnser:
(C) Move the decimal after the number 1.
Step-by-step explanation:
The correct answer is Move the decimal after the number 1. The first step in converting a large number to a scientific notation is to determine the coefficient, which is always greater than 1 and less than 10.

What is the density of an object that has a mass of 20 grams and has a length of 8cm and a width of 2cm and a height of 5cm????
Answer:
Volume is the amount of space an object occupies. To determine the volume of any rectangular object, multiply the measurements of length, width, and height.
Volume = Length × Width × Height
Calculate the volume of this rectangular object.
Length = 3 cm
Width = 3 cm
Height = 12 cm
Volume = l × w × h
Volume = 3 cm × 3 cm × 12 cm
Volume = 108 cm3
Notice that the units for volume are cubic centimeters (cm3).
So 8 ÷ 25 = 0.32 and the units would be g/ cm3 . Other units of density could be g/L or g/ml or mg/ cm3 or kg/ m3 and the list could go on and on. Any unit of mass divided by any unit of volume.

What number must be placed in the box in the equation below to produce an equation that has more than one solution: 5u+3(4u-6)=-3u-27+20u+ ▢
Answer: the number must be placed in the box is 9
suppose: the number must be placed in the box is x
have:
5u + 3(4u - 6) = -3u -27 + 20u + x
⇔ 5u + 12u - 18 = -3u - 27 + 20u +x
⇔ 17u + 3u - 20u = -27 + 18 + x
⇔ 0 = x - 9
⇔ x = 9
Step-by-step explanation:
Answer:
9
Step-by-step explanation:
Simplifying both sides gives
17u - 18 = 17u - 27 + ▢.
Subtracting 17u from both sides gives
-18 = -27 + ▢.
If the number in the box is anything but 9, then the equation cannot be true, and the original equation has no solutions. If the number in the box is 9, then the two sides of the original equation are equivalent, and all values of u are solutions to the equation.
Peter shot 40 free throws. He made 80% of his shots. What fraction is equivalent to 80%? Pleas answer im trying to get my work done over here. Im in math honors and im really not feeling it today so someone please!
Answer:
32 free throws.
Step-by-step explanation:
It is given that,
Peter shot 40 free throws. He made 80% of his shots.
We need to find the fraction that is equivalent to 80%.
It means we have to find 80% of 40. It can be calculated as follows :
[tex]F=\dfrac{80}{100}\times 40\\\\=32[/tex]
80% of 40 is equivalent to 32 free throws.

Which of the following numbers ordered from least go gratest?
0.5, 5/8, 65%, 3/5.
Answer:
0.5 3/5 5/8 65%
Step-by-step explanation:
Answer:
Your answer is 0.5, 3/5, 5/8, 65%.
Step-by-step explanation:
Convert all numbers to decimals:
0.5 = 0.5
5/8 = 0.625
65% = 0.65
3/5 = 0.6
Arrange the numbers accordingly: 0.5, 0.6, 0.625, 0.65. Hence, your answer is 0.5, 3/5, 5/8, 65%.

Step-by-step explanation:
A cardboard box is shaped like a cube. The length of each side is 15 inches.
What is the surface area of the box, in square inches?
Work Shown:
s = side length = 15 inches
SA = surface area of the cube
SA = 6s^2
SA = 6*15^2
SA = 6*225
SA = 1350
The surface area is 1350 square inches.
Note the formula has us compute the area of each square face, which is s*s = s^2. Then we multiply by 6 since there are 6 identical square faces on the cube.
Answer:
1350 [tex]in^{2}[/tex]
Step-by-step explanation:
A cube has six sides. To find the area of a square, multiply the length by itself:
15 x 15 = 225
Since each side is the same (because the box is a cube), simply multiply 225 by 6 (the number of sides on a cube):
225 x 6 = 1350

Brady went on a field trip to the water park. The cost of the trip was $19.99 to get into the park. He bought a hot dog for $3.50 and spent $2.10 on gas money. How much money did Brady spend?
Given:
Cost of the trip to get into the park = $19.99
Brady bought a hot dog for $3.50 and spent $2.10 on gas money.
To find:
The total money Brady spend.
Solution:
It is clear that,
Total money he spend = Cost of the trip to get into the park + Cost of a hot dog + Amount he spent on gas money
On substituting the values, we get
Total money he spend = $19.99 + $3.50 + $2.10
= $25.59
Therefore, the total money Brady spend is $25.59.
Shean has a piece of string 7/8 meter long. He uses 1/5 of he piece of string to tie a package and cuts the rest into 5 equal parts. What is the length of the pieces.
Answer:
7/50 meter
Step-by-step explanation:
Total piece of string = 7/8 meter
Used string = 1/5 of the piece of string
Used string =
1/5 of 7/8 meter
= 1/5 × 7/8
= 7/40 meter
Balance = Total string - used string
= 7/8 - 7/40
= 35-7/40
= 28/40
Balance = 28/40 meter
cuts the rest into 5 equal parts. What is the length of the pieces.
28/40 ÷ 5
= 28/40 × 1/5
= 28 / 200
= 7/50 meter
Length of each piece = 7/50 meter
an architect is designing a commemorative steel arch in the shape of a parabola. its axis is vertical and its feet are 300 yd. apart. If the focus of the parabolic arch is to be 80 yd. above the ground, how high must the arch be?
Answer:
125yd
option b is correct
The height of the arch from the ground will be 125 yards.
Given information:
An architect is designing a commemorative steel arch in the shape of a parabola.
Parabola is vertically placed and its legs are 300 yards apart.
The focus of the parabola is 80 yards above the ground.
Let a be the distance of focus from the vertex of the parabolic arch.
So, the equation of parabola will be,
[tex]x^2=-4ay[/tex]
Assume the origin is placed on the vertex of the parabola.
So, the coordinates of the legs will be,
(-150, -(80+a)) and (150, -(80+a))
Satisfy the above point with the equation of parabola as,
[tex]x^2=-4ay\\150^2=4a(80+a)\\a^2+80a-5625=0[/tex]
Solve the above quadratic equation as,
[tex]x=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}\\a=\dfrac{-80\pm\sqrt{80^2+4\times 1\times5625}}{2}\\a=\dfrac{-80\pm170}{2}\\a=-125, 45[/tex]
The value of a can't be negative. So, [tex]a=45[/tex].
So, the height of arch will be,
[tex]80+a=80+45\\=125\rm\;yd[/tex]
Therefore, the height of the arch from the ground will be 125 yards.
