White bead = [tex]\frac{5}{15} =\frac{1}{3}[/tex]
Answer:
a 33.3333333% chance
Step-by-step explanation:
we do 7+3+5= 15 (the denominator)
and so the amount of white beads in total is 5/15
5÷15+100= 33.333333333 and so on percent
what is 45% of 40 in part, whole, and percent?

Answer:
C
Step-by-step explanation:
4y+3 <= y+6
First, we subtract 3 from each side to get 4y <= y + 3.
Next, we subtract y from each side to get 3y <= 3.
Next, we divide each side by 3 to get y <= 1.
The graph is C.

Uber is running a special! You pay an initial charge of $3.25 plus 1.50 per mile. Write an equation that can be used to find y, the total cost of the trip, if x represents the number of miles of the trip?

y=1.50x+3.25
Step-by-step explanation:
A cleaning company charged $125 to clean a 2500 square foot house. The same company charged $146 to clean a 3200 square foot house. Write an equation in slope-interceptiom to represent the total cost, y, to clean a house with x square feet. Then, find the total cost to clean a house that is 4500 square feet.
Answer:
The cost is y = $185
Step-by-step explanation:
Let us have points spelt out here
(2500,125) and (3200,146)
The general form of a straight line equation is;
y = mx + b
where m is slope
So to calculate the slope in this case, we have
m = (146-125)/(3200-2500)
m = 21/700 = 0.03
So we have the equation as
y = 0.03x + b
To get b, we use any of the two points
Let us use (2500,125)
So we have
125 = 0.03(2500) + b
125 = 75 + b
b = 125-75
b = 50
So the complete equation of the line is;
y = 0.03x + 50
So here, we want to find the cost of a house with 4500 square feet
simply substitute 4,500 for x
y = 0.03(4500) + 50
y = 135 + 50
y = $185

What is the equation of the line parallel to 8x - 16y= -14 and passing through (3, 0)?
Answer:
8x -16y = 24
Step-by-step explanation:
8x - 16y= -14
A parallel line (i.e. same slope) will be: 8x - 16y= c
We have to find the value of "c".
If it passes through (x, y) = (3, 0) ⇒ 24 - 0 = c,
so equation is 8x -16y = 24

Write the equation in point-slope form of the line that passes through the given point and with the given slope m.
(3,-4); m = 6
O y + 4 = 6(x - 3)
O y + 3 = 6(x-4)
O y + 4 = 6(x +3)
O y - 4 = 6(x-3)
Answer:
y + 4 = 6(x - 3)
Step-by-step explanation:
Point-slope form: y - y1 = m(x - x1)
Given: m = 6, (3, -4)
(x1, y1) = (3, -4)
Input the given values into the equation for point-slope form:
y - (-4) = 6(x - 3)
y + 4 = 6(x - 3)
The equation written in point-slope form is: y + 4 = 6(x - 3)

Find the irrational number between 0.3101 and 0.3333
Answer:
π/10
Step-by-step explanation:
Irrational Numbers
The irrational numbers are identified because, unlike rational numbers, they cannot be expressed as fractions, i.e., as the result of a division between two integers.
If a number is expressed with a limited number of decimals, it's always possible to write it as a rational.
For example, number 1.2319 can be written as 12319/10000.
Even if the number has an unlimited decimal expression, it could be expressed as rational if the decimal part is periodic. Number 2.33333... is rational because it's equivalent to the fraction 7/3.
We need to find an irrational number between 0.3101 and 0.3333.
Any number within the range with unlimited non-periodic decimals will do:
0.3189567363.... is a good example.
We'll choose the number
π/10 since π is a known irrational number and π/10=0.3141592... lies in the given interval.

A block of wood is in the shape of a rectangular prism with dimensions (n+5) cm, (n+8) cm, and (n+14) cm. All faces of the block are painted, and then the block is cut into 1 cm cubes using parallel cuts to each face. If exactly half of the cubes have no paint on them, find the total number of cubes.
Answer:
The total number of cubes in the rectangular prism are 1,120 cubes
Step-by-step explanation:
The given parameters are;
The dimensions of the rectangular prism block of wood = (n + 5), (n + 8), and (n + 14)
The volume of the block of wood = (n + 5)×(n + 8)×(n + 14) = n³ + 27·n² + 222·n + 560
The quantity of the 1 cm cubes that have no paint = 1/2 of the total quantity = 1/2 the volume of the original cube
The cubes that have paint on them are the surface cubes, we have;
One layer of cube is removed from each of the eight sides, therefore, we have the dimensions of the cube rectangular prism that have no paint on them given as (n + 5 - 2), (n + 8 - 2), and (n + 14 - 2), which gives the dimensions as (n + 3), (n + 6), and (n + 12);
Therefore, we have
2 × (n + 3)×(n + 6)×(n + 12) = (n + 5)×(n + 8)×(n + 14)
2 × (n + 3)×(n + 6)×(n + 12) - (n + 5)×(n + 8)×(n + 14) = 0
Which gives;
n³ + 15·n² + 30·n - 128 = 0
n = 2
n = -17/2 - √(33)/2 = -5.6277
n = √(33)/2 - 17/2 = -11.3722
Therefore, given that the smallest dimension of the painted prism = (n + 5), the possible value for n = 2
The volume of the rectangular prism = (n + 5) × (n + 8) × (n + 14) = (2 + 5) × (2 + 8) × (2 + 14) = 1120 cm³
Given that the cuts are 1 cm³ each, the total number of cubes in 1,120 cm³ = 1,120 cubes.

Answer:
A
Step-by-step explanation:

Answer: D and B
Step-by-step explanation:
The range (answered by D) is only the multiples of 15 between 0 and 60 as it is impossible to pay an amount different than the correct inclinations of 1/15 per candy. For example, it is impossible to pay 12.345421 dollars for a candy.
A similar solution applies for the domain. Only integers(whole numbers) are valid as you cannot buy 1.2862 of a candy.

The formula for throwing a baseball in the air is represented by the attached function, where h represents the height of the ball in inches, and t represents time. How high is the baseball after 3 and a half seconds?
h(t)=-3t^2+12t+40
Answer:
45.25 in
Step-by-step explanation:
To solve this question you would plug 7/2 or 3.5 in for t and solve for h(t).
h(t)=-3(7/2)^2+12(7/2)+40
=-3(49/4)+(84/2)+40
=(-147/4)+42+40
=-36.75+42+40
=45.25 in

Step-by-step explanation:
The position of an object in a video game is represented by an ordered pair. The coordinates of the ordered pair give the
number of pixels horizontally and vertically from the origin. Use this scenario for Exercise.
a. Suppose that player A is located at (36, 315) and player B is located at (410, 53). How far apart are the players? Round to
the nearest pixel
b. If the two players move directly toward each other at the same speed, where will they meet?
c. If player A moves three times faster than player B, where will they meet? Round to the nearest pixel.
Answer:
a. 457 pixels b. 229 pixels c. 114 pixels
Step-by-step explanation:
a. Using d = √[(x₂ - x₁)² + (y₂ - y₁)²] to find the distance apart of the coordinates (x₁, y₁) and (x₂, y₂) where (x₁, y₁) = (36, 315) and (x₂, y₂) = (410, 53).
So, d = √[(x₂ - x₁)² + (y₂ - y₁)²]
= √[(410 - 36)² + (53 - 315)²]
= √[374² + 262²]
= √[139,876 + 68,644]
= √208,520
= 456.64
= 457 pixels to the nearest pixel.
b. Since the players are d' distance apart, and moving at a same speed of v, if they approach each other, they meet at time t. So player A covers a distance of d = vt. For them to meet, player B approaches and covers a distance of d = d' - vt. So they meet when vt = d' - vt.
Solving this, we have
vt = d' - vt
vt + vt = d'
2vt = d'
t = d'/2v
Substituting t into d = vt, we have
d = vt
= v(d'/2v)
= d'/2
= 457/2
= 228.5
≅ 229 pixels to the nearest pixel
c. Since the players are d' distance apart, and player A moves at a speed three times that of player B, if player B moves with speed v, then player A moves with speed 3v, as they approach each other, they meet at time t. So player A covers a distance of d = 3vt. For them to meet, player B approaches and covers a distance of d = d' - vt. So they meet when 3vt = d' - vt.
Solving this, we have
3vt = d' - vt
3vt + vt = d'
4vt = d'
t = d'/4v
Substituting t into d = vt, we have
d = vt
= v(d'/4v)
= d'/4
= 457/4
= 114.25
≅ 114 pixels to the nearest pixel
