Answer: ok so Let's simplify step-by-step.
r−3q+5p−(−4r−3q−8p)
Distribute the Negative Sign:
=r−3q+5p+−1(−4r−3q−8p)
=r+−3q+5p+−1(−4r)+−1(−3q)+−1(−8p)
=r+−3q+5p+4r+3q+8p
Combine Like Terms:
=r+−3q+5p+4r+3q+8p
=(5p+8p)+(−3q+3q)+(r+4r)
=13p+5r
Step-by-step explanation:
Answer:
5r + 13p
Step-by-step explanation:
In this question, you would simplify the expression.
Solve:
(r - 3q + 5p) - (-4r - 3q - 8p)
Use the distributive property to distribute the negative to the variables inside the parenthesis.
r - 3q + 5p + 4r + 3q + 8p
Combine like terms.
r - 3q + 5p + 4r + 3q + 8p
5r - 3q + 5p + 3q + 8p
5r + 5p + 8p
5r + 13p
Since we can't simplify further, your final answer would be 5r + 13p

Step-by-step explanation:
A rectangular yard measuring 37' x 43' is bordered and surrounded by fence. Inside, a walk that is 2 foot wide goes all the way along the fence. Find the area of this walk.
Answer:
[tex]A=160ft^2[/tex]
Step-by-step explanation:
Length of yard [tex]l=37ft[/tex]
Width of yard [tex]w=43ft[/tex]
Walk [tex]l_w=2ft[/tex]
Generally the perameter of the fence P is mathematically given by
[tex]P=l+w[/tex]
[tex]P=37+43[/tex]
[tex]P=80[/tex]
Generally the equation for area of walk is mathematically given by
[tex]A=P*l_w[/tex]
[tex]A=80*2[/tex]
[tex]A=160 ft^2[/tex]
Therefore area of walk is
[tex]A=160ft^2[/tex]
Find the ten missing angles labeled in the diagram. Line a is parallel to line b. The measures of two angles are given.
Answer:
m∠3 = 112° m∠5 = 38° m∠6 = 68° m∠8 = 74°
You do the others
Step-by-step explanation:
Facts you need to solve this problem.
1. Vertical angles are congruent
2. Alternate interior angles are congruent when lines are parallel
3. Sum of the measures of the angles of a triangle is 180
4. Adjacent angles are supplementary when two lines intersect
m∠3 = 112° (Reason 1 above)
m∠6 = 180 - 112 = 68° (Reason 4)
m∠6 + m∠5 + 74 = 180° (Reason 3)
68 + m∠5 + 74 = 180
142 + m∠5 = 180
m∠5 = 38°
m∠8 = 74° (Reason 2)
That gives you a start, so I will let you find all the others. OK? I know you don't want to do that, but you need to be able to do this type of problem. Now, go for it!!

A sports memorabilia collector needs to create a display case to show her baseball cards
at a garage sale. She will create the case in the shape of a rectangular prism with no lid.
The box will be created by cutting square corners out of a piece of cardboard with
dimensions 40 inches by 60 inches. What equation should be used to maximize the
volume of the box?
Answer:
For a box of length L, width W, and height H, the volume is:
V = H*L*W
in this case, we have a piece of cardboard of dimensions 40in by 60 in.
If we cut squares of side length X in the corners and we fold the corners, we will have a height of X.
And we can define:
Length = 60in - X
Width = 40 in - X
Then the volume of the box will be:
V = X*(60in - X)*(40in - X)
V = X^3 - 100in*X^2 + 2400in^2*X
We want to maximize this, then we need to find the zero of the first derivative.
We have that:
V' = 3*X^2 - 2*100in*X + 2400in^2
V' = 3*X^2 - 200in*X + 2400in^2
This is the equation we will use to maximize the volume of the box, but let's not end here, let's complete the problem and find the value of X and the maximum volume.
We want to solve:
V' = 0 = 3*X^2 - 200in*X + 2400in^2
For X.
Then we can use Bhaskara's formula, we will get that the solutions are:
[tex]X = \frac{-(-200in) +-\sqrt{(-200in)^2 - 4*3*(2400in)} }{2*3} = \frac{200in +- 105.8in}{6}[/tex]
Then we have two possible solutions for X.
X = (200in + 105.8in)/6 = 50.97 in
But this is larger than the side of 40 in, so we can not cut this much, we can discard this option.
The other one is:
X = (200in - 105.8in)/3 = 15.7in
This seems correct.
Then the maximum volume of the box is:
V = 15.7in*(60in - 15.7in)*(40in - 15.7in) = 16,900.893 in^3

The heights of young American women, in inches, are approximately Normally distributed with mean μ and standard deviation σ = 2.4. If I want to construct a 99% confidence interval with a margin of error of no more than ± 1 inch, what is the smallest sample I can select?
The smallest sample size needed to construct a 99% confidence interval with a margin of error of no more than ±1 inch is 39.
The margin of error (E) for a confidence interval is described as:
E = z × (σ / √n)
where:
E is the desired margin of error
z is the z-score corresponding to the desired confidence level (in this case, 99% confidence level)
σ is the population standard deviation
n is the sample size
In this case, the margin of error is no more than ±1 inch, so E = 1 inch.
Now, determine the z-score corresponding to a 99% confidence level using a standard normal distribution table or statistical software.
For a 99% confidence level, the z-score is approximately 2.576.
Plugging in the known values into the margin of error formula,
1 = 2.576 × (2.4 / √n)
To solve for n, rearrange the formula as follows:
√n = (2.576 × 2.4) / 1
√n = 6.1824
n = (6.1824)²
n ≈ 38.16
Therefore, the smallest sample size needed to construct a 99% confidence interval with a margin of error of no more than ±1 inch is 39.

Solving steps
We know x= -10-15y, so we can subtract it to the equation above
x = -10-15y
2x+5y=35
2(-10-15y) + 5y = 35
(Refer to the 1st image to solve for y)
Y = -11/5
We now know y= -11/5, so we can subtract it to the equation for x.
Y = -11/5
x = -10-15y
x = -10-15(-11/5)
(Refer to the 2nd and 3rd image to solve for x) (Make sure to look at both images first before writing something down)
x = 33 - 10
x = 23
