Answer:
Clair, since there isn't an attached picture, we don't know some info
Step-by-step explanation:
but here is how you can figure this out....
they tell use to give 6 inches on each side of the door, so the total width of the logo can be 2 feet wide. Because the door is 3 feet wide. Now use that to find the height. find the height to width ratio of the logo, so if the logo is 4 feet wide and 6 feet tall it's 6/4 or 1.5 ratio, use that and multiply by the 2 that we know the width can be on the door. so 2*1.5 = 3. the height of the logo would be 3 feet tall and 2 feet wide on the door. see?
just find the ratio of the logo, and multiply that by 2 :) to find the height on the door, got it?
what is the distance between these two numbers -3 1/4 and 4 1/2
Answer:
7 3/4
Step-by-step explanation:
Method 1:
Step 1: Instead of subtracting you distribute the minus sign to the number in the parenthesis
4 1/2 - (-3 1/4) = 4 1/2 + 3 1/4
Step 2: Then you can just add
4 1/2 + 3 1/4= 7 3/4
Method 2:
If you dont know fractions transfer them into decimals. 1/2 = 0.5 and 1/4 = 0.25
Step 1: Instead of subtracting you distribute the minus sign to the number in the parenthesis
4.5 - (-3.25) = 4.5 + 3.25
Step 2: Add the numbers
4.5 + 3.25= 7.75
Step 3: Convert the decimal back into a fraction
7.75= 7 3/4

The Payans have just learned that the bank will approve them for a mortgage at an APR of 4.3% for 30 years if they meet the back-end ratio requirement. To determine whether they’ll meet the requirement, the back-end ratio needs to be calculated with the actually monthly payment rather than the estimate used in part A. Use this monthly payment formula to calculate the Payans’ monthly mortgage payment.
The annual percentage rate (APR) for the Payans is the yearly interest rate that's generated by a sum charged to borrowers.
What is APR?Your information is incomplete as the values aren't given. Therefore, an overview will be given. Here, the APR is the cost that one has to pay to borrow money and it's expressed as a percentage.
Also, the mortgage payment is made up of the principal and the interest payments. It's how one will pay back their home loan.

A homebuyer is building a home and has sat down with an architect. The buyer tells the architect the perimeter of the house must be 200
feet. The dimensions of the house that would give the buyer the maximum area would be which of the following?
A 10 x 90 feet
B 20 x 80 feet
C 30 x 70 feet
40 x 60 feet
E 50 x 50 feet
Answer:
[tex]50\; {\rm ft} \times 50\; {\rm ft}[/tex] would maximize the area for a rectangle with the given circumference of [tex]200\; {\rm ft}[/tex]. (Note, that a circle of the same circumference would have an even larger area.)
Step-by-step explanation:
Assume that the base of the house is a rectangle. Let the length of the two sides be [tex]x\; {\rm ft}[/tex] and [tex]y\; {\rm ft}[/tex], respectively. The goal is to find the [tex]x[/tex] and [tex]y[/tex] that:
[tex]\begin{aligned} \text{maximize} \quad & x\, y \\ \text{subject to} \quad & 2\, (x + y) = 200 \\ & x > 0 \\ & y > 0 \end{aligned}[/tex].
Using the equality constraint [tex]2\, (x + y) = 200[/tex] (or [tex]x + y = 100[/tex]), the variable [tex]y[/tex] could be replaced with [tex](100 - x)[/tex] to obtain an equivalent problem of only one variable:
[tex]\begin{aligned} \text{maximize} \quad & x\, (100 - x) \\ \text{subject to} \quad & x > 0 \\ & (100 - x) > 0 \end{aligned}[/tex].
Simplify to obtain:
[tex]\begin{aligned} \text{maximize} \quad & -x^{2} + 100\, x \\ \text{subject to} \quad & x > 0 \\ & x < 100 \end{aligned}[/tex].
The objective function of this problem is [tex]f(x) = -x^{2} + 100\, x[/tex]. Derivatives of this function include
[tex]f^{\prime}(x) = -2\, x + 100[/tex] and[tex]f^{\prime\prime}(x) = -2[/tex].Since [tex]f^{\prime\prime}(x)[/tex] is constantly less than [tex]0[/tex], [tex]f(x)[/tex] is concave and would be maximized when [tex]f^{\prime}(x) = 0[/tex].
Setting [tex]f^{\prime}(x) = -2\, x + 100[/tex] to [tex]0[/tex] and solving for [tex]x[/tex] gives:
[tex]-2\, x + 100 = 0[/tex].
[tex]x = 50[/tex].
Notice that [tex]x = 50[/tex] satisfies both constraints: [tex]x > 0[/tex] and [tex]x < 100[/tex]. Therefore, [tex]x = 50[/tex] is indeed the solution that maximizes the area [tex]f(x) = -x^{2} + 100\, x[/tex] while at the same time meeting the requirements.
With the length of one side being [tex]x = 50[/tex] ([tex]50\; {\rm ft}[/tex],) the length of the other side would be [tex]100 - x = 50[/tex] ([tex]50\; {\rm ft}\![/tex].) Hence, a rectangular house of dimensions [tex]50\; {\rm ft} \times 50\; {\rm ft}[/tex] would maximize the area under the given requirements.

Step-by-step explanation:
Please solve and show work!!! Need by tomorrow look at attached photo!!<44
Answer:
1.
First, I would solve for ACB.
Calculations:
63° = y?
I would do that because I know that angle 'y' is vertical to 63°, which is given. (Also vertical angles are congruent, meaning that the measure the same degrees).
2.
Second, I would solve for BAC.
Calculations:
x + 63 + 85 = 180
x + 148 = 180
-148 -148
x = 32°
I would do that because I know that there are two given angles so I could easily solve for the leftover angle, 'z', using the a + b + c = 180° formula.
3.
Next, I would solve for CED.
Calculations:
x + 130 = 180
-130 -130
x = 50°
I would do that because I know finding this angle will help me find angle CDE.
4.
Finally, I would solve for CDE.
Calculations:
x + 63 + 50 = 180
x + 113 = 180
-113 -113
x = 67°
I would do that because I know there are now two given angles so I could easily solve for the leftover angle, x, using the a + b + c = 180° formula.

Answer:
31/40
Step-by-step explanation:
Given expression:
[tex]\dfrac{2}{5} + \dfrac{3}{8}[/tex]
Note: Both fractions must have same denominators if we want to perform addition, subtraction, multiplication, or division.
The only way to simplify this expression is to have a common denominator, which can be determined by the LCM of 5 and 8.
⇒ Multiples of 5: 5, 10, 15, 20, 25, 30, 35, 40, 45...⇒ Multiples of 8: 8, 16, 24, 32, 40, 48, 56, 64, 72...Multiply the denominators with such a number that is equivalent to 40.
Note: The number you are multiplying should also be multiplied to the numerator.
[tex]\rightarrow \dfrac{2 \times 8}{5 \times 8} + \dfrac{3 \times 5}{8 \times 5}[/tex]
[tex]\rightarrow \dfrac{16}{40} + \dfrac{15}{40}[/tex]
Finally, simplify the expression to determine the solution.
[tex]\rightarrow \dfrac{31}{40}[/tex]
Since 31 is a prime number, we can't simplify this fraction. Thus, the final answer is 31/40.
Ah yes, adding fractions! Adding fractions can be a bit of a pain.
So, we have [tex]\frac{2}{5} + \frac{3}{8}[/tex].
To add fractions, the bottoms, or denominators, must be the same number. So we must multiply the fractions by certain numbers to make the denominators the same number. So let's go easy and make the denominator 40, because 8 goes into 40 and so does 5. So, to make 8 become 40, we'll multiply the whole fraction by 5. For 5, we'll multiply by 8.
[tex]5 * \frac{3}{8} = \frac{15}{40}[/tex]
[tex]8 * \frac{2}{5} = \frac{16}{40}[/tex]
Now we'll add the two fractions. When we add fractions we only add the tops, the numerators.
[tex]\frac{15}{40}+\frac{16}{40} = \frac{31}{40}[/tex]
Then we must reduce (or try to reduce). This fraction cannot be reduced, so the answer is simply [tex]\frac{31}{40}[/tex].
I hope this helps you understand.

A camera has a listed price of 643.99 before tax. If the sales tax rate is 9.75%, find the total cost of the camera with sales tax included. Round your answer to the nearest cent, as necessary.
Answer: $1,271.88
Step-by-step explanation:
The total cost of the camera with sales tax included will be 100% plus our sales tax:
100% + 9.75% = 109.75%
Dividing a percent (%) by 100 gives us a decimal:
109.75% / 100 = 1.975
We can multiply this decimal by the listed price of the camera to find our answer
643.99 * 1.975 = $1,271.88
The camera will cost $1,271.88 with sales tax.

Step-by-step explanation:
Standard form of a parabola with a horizontal axis of symmetry:
[tex](y-k)^2=4p(x-h)\quad \textsf{where}\:p\neq 0[/tex]
[tex]\textsf{Vertex}=(h, k)[/tex]

Given equation:
[tex]x=-\dfrac18y^2[/tex]
Rewrite in standard form:
[tex]\implies (x-0)=-\dfrac18(y-0)^2[/tex]
[tex]\implies -8(x-0)=(y-0)^2[/tex]
[tex]\implies (y-0)^2=-8(x-0)[/tex]
Comparing with the general standard form:
k = 0h = 04p = -8 ⇒ p = -2Therefore:
[tex]\textsf{Vertex }(h,k)=(0,0)[/tex]
[tex]\textsf{Focus }(h+p,k)=(0-2,0)=(-2,0)[/tex]
