At a large nursery, a border for a rectangular garden is being built. Designers want the border’s length to be twice as long as its width. A maximum of 150 ft of fencing is available for the border. Write and solve an inequality that describes possible widths of the garden.
Let
x--------> the border’s length
y--------> the border’s width
P--------> perimeter of the border
we know that
x=5+y------> equation 1
P=2*[x+y]-----> P=2x+2y
P <=180 ft
(2x+2y) <= 180-------> equation 2
substitute the equation 1 in equation 2
2*[5+y]+2y <= 180
10+2y+2y <= 180
4y <= 180-10
4y <=170
y <=42.5 ft
so
the maximum value of the width is 42.5 ft
for y=42.5 ft
x=42.5+5------> x=47.5 ft
the answer is
the width of the border is less than or equal to 42.5 ft

9514 1404 393
Answer:
13/2 or 6 1/2
Step-by-step explanation:
We can write the question in the form of an equation:
13/16 = n×1/8
Multiplying by 8 gives ...
8×13/16 = n
13/2 = n = 6.5
The number of 1/8 in 13/16 is 6 1/2 or 13/2.

Angle Relationships
Answer:
In Geometry, there are five fundamental angle pair relationships:
Complementary Angles.
Supplementary Angles.
Adjacent Angles.
Linear Pair.
Vertical Angles.
The measure of the angle u and angle t will be 29 degrees.
What is an angle?The angle is the distance between the intersecting lines or surfaces. The angle is also expressed in degrees. The angle is 360 degrees for one complete spin.
Supplementary angle - Two angles are said to be supplementary angles if their sum is 180 degrees.
The angle u is congruent to angle t.
From the diagram, angle t, angle u, and angle 122 are supplementary angles. Then the equation is given as,
∠t + ∠u + 122° = 180°
∠t + ∠t = 58°
2∠t = 58°
∠t = 29°
The measure of the angle u and angle t will be 29 degrees.

Pascha is factoring the polynomial, which has four terms.
3x3 – 15x2 + 8x – 40
3x2(x – 5) + 8(x – 5)
Which is the completely factored form of her polynomial?
(3x2 – 5) (x + 8)
(3x2 – 8) (x + 5)
(3x2 + 8) (x – 5)
(3x2 + 5) (x – 8)
Answer:
[tex](3x^2 + 8)(x - 5)[/tex]
Step-by-step explanation:
Given
[tex]3x^3 - 15x^2 + 8x - 40 = 3x^2(x - 5) + 8(x - 5)[/tex]
Required
Complete the factorization
[tex]3x^3 - 15x^2 + 8x - 40 = 3x^2(x - 5) + 8(x - 5)[/tex]
When an equation is factorized as:
[tex]a(b + c) + d(b + c)[/tex]
The complete expression is:
[tex](a + d)(b + c)[/tex]
Apply this logic in [tex]3x^3 - 15x^2 + 8x - 40 = 3x^2(x - 5) + 8(x - 5)[/tex]
By comparison:
[tex]a = 3x^2; b = x; c = -5; d = 8[/tex]
So, we have:
[tex]3x^3 - 15x^2 + 8x - 40 = (3x^2 + 8)(x - 5)[/tex]
Hence,
[tex](3x^2 + 8)(x - 5)[/tex] is the complete factor

What is the volume of this rectangular prism?
Answer:
[tex]V =\frac{12}{5}\ cm^3[/tex]
Step-by-step explanation:
The Volume of Rectangular Prism
Given a rectangular prism of dimensions W, L, and H, its volume is the product of the three dimensions:
V = WLH
The figure shows the dimensions:
L=3 cm
[tex]W=\frac{4}{3}\ cm[/tex]
[tex]H=\frac{3}{5}\ cm[/tex]
Thus, the volume is:
[tex]V =3*\frac{4}{3}*\frac{3}{5}\ cm^3[/tex]
[tex]V =\frac{36}{15}\ cm^3[/tex]
Simplifying:
[tex]\boxed{V =\frac{12}{5}\ cm^3}[/tex]
A random sample of 17 students, taught in traditional lab sessions, had a mean test score of 71.5 with a standard deviation of 4.8. A random sample of 13 students, taught using interactive simulation software, had a mean test score of 78.5 with a standard deviation of 6. Do these results support the claim that the mean science test score is lower for students taught in traditional lab sessions than it is for students taught using interactive simulation software
Answer:
The calculated value of t= -0.9468 does not lie in the critical region t= -1.701. Therefore we accept our null hypothesis that mean science test score is lower for students taught in traditional lab sessions than it is for students taught using interactive simulation software at the 0.05 significance level
Step-by-step explanation:
Categories Sample Size Mean Standard D
Traditional Lab 17 71.5 4.8
Software 13 78. 5 6
We are using Student's t- test considering that the population variance is equal.
We formulate null and alternate hypotheses are
H0 : u1 < u2 against Ha: u1 ≥ u 2
The Significance level alpha is chosen to be ∝ = 0.05
The critical region t ≤ -t (0.05, 28) = -1.701
Degrees of freedom is calculated df = υ= n1+n2- 2= 17+13-2= 28
Here the difference between the sample means is x`1- x`2= 71.5-78.5= -7
The pooled estimate for the common variance σ² is
Sp² = 1/n1+n2 -2 [ ∑ (x1i - x1`)² + ∑ (x2j - x`2)²]
= 1/17+13-2 [ 71.5²+78.5²]
Sp = 20.0664
The test statistic is
t = (x`1- x` ) /. Sp √1/n1 + 1/n2
t= -7/ 20.0664 √1/17+ 1/13
t= -7/7.393
t= -0.9468
The calculated value of t= -0.9468 does not lie in the critical region t= -1.701. Therefore we accept our null hypothesis that mean science test score is lower for students taught in traditional lab sessions than it is for students taught using interactive simulation software at the 0.05 significance level
The function t relates the age of a plant fossil, in years, to the percentage, c, of carbon-14 remaining in the fossil relative to when it was alive.
t(c)=-3,970(ln c)
Use function t to complete the statements.
A fossil with 47% of its carbon-14 remaining is approximately ___ years old.
A fossil that is 7,000 years old will have approximately ___ of its carbon-14 remaining.
Applying the logarithmic function, it is found that:
A fossil with 47% of its carbon-14 remaining is approximately 2997 years old.A fossil that is 7,000 years old will have approximately 56.71% of its carbon-14 remaining.The age of a fossil with a proportion c of carbon 14 remaining is given by:
[tex]t(c) = -3970\ln{c}[/tex]
If the fossil has 47% of carbon-14 remaining, we have that [tex]c = 0.47[/tex], and thus:
[tex]t(0.47) = -3970\ln{0.47} = 2997[/tex]
For a fossil that is 7000 years old, we have that [tex]t(c) = 7000[/tex], and hence:
[tex]t(c) = -3970\ln{c}[/tex]
[tex]\ln{c} = -\frac{3970}{7000}[/tex]
[tex]e^{\ln{c}} = e^{-\frac{3970}{7000}}[/tex]
[tex]c = 0.5671[/tex]
A fossil that is 7,000 years old will have approximately 56.71% of its carbon-14 remaining.
