Answer:
8
Step-by-step explanation:
If the gardener bought more white than pink, that could mean he could have bought 12 white and one pink, 11 white and 2 pink, 10 white and 3 pink, 9 white and 4 pink, 8 white and 5 pink, or 7 white and 6 pink.
If you plug in the numbers, for example with 7 and 6, that would equal $53, which is not correct. Continue to do this with all of the answers.
With 8 white roses and 5 pink roses, this would equal $55 (40+15), which is the answer.
By solving form expressions the gardener bought 5 pink plants.
What is an expression?In mathematics, an expression is a combination of one or more numbers, variables, constants, and operators, which when evaluated, produce a value. Expressions can include mathematical symbols such as addition, subtraction, multiplication, division, exponents, roots, logarithms, and trigonometric functions.
Let's use algebra to solve this problem.
Let's assume that the gardener bought x pink plants and y white plants. We know that:
The gardener bought 13 plants in total: x + y = 13
The gardener spent $55: 3x + 5y = 55
The gardener chose more white plants than pink: y > x
We can use the first equation to solve for x in terms of y:
x = 13 - y
Now we can substitute this into the second equation:
3(13 - y) + 5y = 55
Simplifying and solving for y:
39 - 3y + 5y = 55
2y = 16
y = 8
So the gardener bought 8 white plants. To find out how many pink plants were bought, we can substitute this value into the first equation:
x + y = 13
x + 8 = 13
x = 5
So the gardener bought 5 pink plants.

Complete the point-slope equation of the line through (-1,6) and (1,5).
Use exact numbers.
Y= 6
Answer:
Y-6=-1/2(x-(-1) )
Step-by-step explanation:
The Equation for the point-slope of the line is y - 6 = -1/2(x + 1).
What is the slope of a line?A line's slope is defined as the ratio of the change in y coordinates to the change in x coordinates.
Both the net change in the y-coordinate and the net change in the x-coordinate are denoted by y and x, respectively.
Given coordinates (-1,6) and (1,5).
the slope of line is given by,
m = (y₂- y₁)/(x₂ - x₁)
y₂- y₁ = 5 - 6 = -1
x₂ - x₁ = 1 - (-1) = 2
m = -1/2
to find the equation at y = 6
when y = 6, x = -1
the equation is given by
y - y₁ = m(x - x₁)
y - 6 = -1/2(x -(-1))
y - 6 = -1/2(x + 1)
Hence equation of a line is y - 6 = -1/2(x + 1).

Answer:
The number of tigers decays by a factor of
[tex]\dfrac{4}{5}[/tex] every 0.50 years
Explanation:
The correctly written function is
[tex]N(t)=650\cdot \bigg(\dfrac{16}{25}\bigg)^t[/tex]
Convert 16/25 into its equivalent form (4/5)²
[tex]N(t)=650\cdot \bigg(\dfrac{4}{5}\bigg)^{2t}[/tex]
If you make t = 1/2, this is half-year, the population of tigers will decay by a factor of 4/5 in that time. Every time the half-year passes, the population is multiplied by 4/5, which means that the polulation will decay by a factor of 4/5 whenever half a year elapses.
Hence, the number of tigers decays by a factor of 4/5 every 0.50 years.
The tiger population model indicates a decay by a factor of 4/5 every year. This factor shows the yearly reduction rate for the tiger population in Siberia.
To determine the rate of change in the tiger population modeled by the function N(t) = [tex]650 \cdot \left(\frac{16}{25}\right)^t,[/tex] we look at the decay factor in the exponential function. The base of the exponent, [tex]\frac{16}{25}[/tex], indicates that the population is decaying.
This decay factor can be expressed as [tex]\frac{4}{5}[/tex], where every year, the number of tigers decays by a factor of [tex]\frac{4}{5}[/tex]. Thus, we can complete the sentence as follows:
The number of tigers decays by a factor of [tex]\frac{4}{5}[/tex] every year.
A square in a rectangle have the same perimeter. The length of a side of the square is 4x-1. The length of the rectangle is 2x+2 and the width is 2x
The value x is 1, if the perimeter of square and rectangle are same. The perimeter of square and rectangle is 12 units.
Step-by-step explanation:
The given is,
A square in a rectangle have the same perimeter
The length of a side of the square is 4x-1
The length of the rectangle is 2x+2 and width is 2x
Step:1
Let, a - Side of square
l - Length of the rectangle
w - Width of the rectangle
Step:2
Formula for perimeter of square is,
[tex]p=4a[/tex].............................(1)
Formula for perimeter of rectangle is,
[tex]p=2(l+w)[/tex]....................(2)
Step:3
From given,
Equation (1) = Equation (2)
[tex]4a = 2 (l+w)[/tex]
where,
a = 4x-1
l = 2x+2
w = 2x
Substitute the values,
4 ( 4x-1 ) = 2 ( 2x+2+2x )
16x - 4 = 2 (4x + 2)
16x - 4 = 8x + 4
16x - 8x = 8
8x = 8
x = 1
Step:4
Substitute the values of x,
a = 4(1)-1 = 3
l = 2(1)+2) = 4
w = 2(1) = 2
Perimeter of square and rectangle is 12 units
Result:
The value x is 1, if the perimeter of square and rectangle are same. The perimeter of square and rectangle is 12 units.

PLZZ HELPPP!!! Each edge of a wooden cube is 6 centimeters long. The cube has a density of 0.71 g/cm3
.
What is the mass of the wooden cube?
Enter your answer in the box.
g
Answer:
153.36g
Step-by-step explanation:
Density is defined as the ratio of mass per unit volume of a material.
Density = Mass/Volume
Given the edge of a cube which is equivalent to its length L to be 6cm.
Density of the cube = 0.71g/cm³
Volume of the cube = L³
Volume = 6³
Volume of the cube = 216cm³
Mass = Density × Volume
Mass of the cube = 0.71×216
Mass of the cube = 153.36grams
Answer:
153.36 grams
Step-by-step explanation:
Density is mass divided by volume: d = m/v.
Here, we already know that d = 0.71 g/cm³.
We can find the volume of hte cube. The volume of a cube is denoted by:
V = s³, where s is the side length
The cube's length is 6, so plug this in:
V = s³
V = 6³ = 216 cm³
Plug these values in:
d = m/v
0.71 g/cm³ = m / 216 cm³
m = 0.71 * 216 = 153.36 grams
The answer is 153.36 grams.

Point A (-3, 5) is rotated 180º about the origin. What are the coordinates of A' after the rotation?
A point when rotated 180º about the origin flips the sign of the coordinates. Thus, point A' after rotating point A (-3,5) 180º about the origin would have coordinates (3,-5).
Explanation:A rotation of 180º about the origin essentially changes the signs of the coordinates. If we have Point A as (-3, 5), after a 180° rotation about the origin, you'll get Point A', which will be the opposite of Point A. That means it turns (-3, 5) to (3, -5).
Rotation about the origin flips the point across both axes. This is based on a rule in mathematics: When we rotate a point 180° about the origin, (x, y) becomes (-x, -y).
The coordinates of A' after the 180° rotation are (3, -5).

Answer:
volume ≈ 572.27 mm³
Step-by-step explanation:
The icicle is in the shape of an inverted cone with a diameter of 9 mm and a height of 27 mm. To find how much in cubic millimetres the frozen water is in the icicle can be calculated below.
In other words the question want us to find the volume of the cylinder. The volume of the cone can be represented as follows:
volume of a cylinder = 1/3πr²h
where
r = radius
h = height
diameter = 9 mm
height = 27 mm
r = diameter/2 = 9/2 = 4.5
volume = πr²h
volume = 1/3 × 3.14 × 4.5² × 27
volume = 1/3 × 3.14 × 20.25 × 27
volume = 1/3 × 63.585 × 27
volume = 1716.795/3
volume = 572.265 mm³
volume ≈ 572.27 mm³
