Step-by-step explanation:
The width of a rectangle is 4n - 4.5 feet and the length is 4.5n + 9 feet. Find the perimeter of the
rectangle.
9514 1404 393
Answer:
17n+9 feet
Step-by-step explanation:
The perimeter of a rectangle is twice the sum of length and width.
P = 2(L +W)
P = 2((4.5n +9) +(4n -4.5)) = 2(8.5n +4.5)
P = 17n +9
The perimeter of the rectangle is 17n +9 feet.
If AC = 14, what is the measure of AD? Round your answer to the nearest hundredth.
Part A
Answer: Choice D) [tex]\text{AD} = \sqrt{(2n+5)^2+(4n-3)^2}[/tex]
-----------------------------------------------
Explanation:
Let E be the intersection point of the diagonals. For any parallelogram, the diagonals bisect each other. This means that AE = EC = 2n+5 and it also means EB = DE = 4n-3
Focus on triangle AED. This triangle is a right triangle with angle AED as a 90 degree angle (any rhombus has its diagonals that are perpendicular to one another). The legs of this triangle are AE = 2n+5 and ED = 4n-3
Apply the pythagorean theorem to find hypotenuse AD
[tex](\text{leg1})^2+(\text{leg2})^2 = (\text{hypotenuse})^2\\\\(\text{AE})^2+(\text{ED})^2 = (\text{AD})^2\\\\(\text{AD})^2 = (\text{AE})^2+(\text{ED})^2\\\\\text{AD} = \sqrt{(\text{AE})^2+(\text{ED})^2}\\\\\text{AD} = \sqrt{(2n+5)^2+(4n-3)^2}\\\\[/tex]
This points to choice D as the final answer.
===========================================================
Part B
Answer: 7.07-----------------------------------------------
Explanation:
If AC = 14, then half of this is AE = 7. The diagonals bisect each other, so they cut each other in half with E at the midpoint.
Since AE = 2n+5, we can solve for n like so
2n+5 = 7
2n = 7-5
2n = 2
n = 2/2
n = 1
Then we can find the length of AD
[tex]\text{AD} = \sqrt{(2n+5)^2+(4n-3)^2}\\\\\text{AD} = \sqrt{(2*1+5)^2+(4*1-3)^2}\\\\\text{AD} = \sqrt{(2+5)^2+(4-3)^2}\\\\\text{AD} = \sqrt{7^2+1^2}\\\\\text{AD} = \sqrt{49+1}\\\\\text{AD} = \sqrt{50}\\\\\text{AD} \approx 7.0710678\\\\\text{AD} \approx 7.07\\\\[/tex]
Segment AD is roughly 7.07 units long. The other external sides of the rhombus (AB, BC and CD) are also this length because the four sides of any rhombus are the same length.
Classify the polynomial by Degree and number of Terms
b^3+2b^2-b^2+3b^2+25
A. Quadratic Polynomial
B. None of the answers apply.
C. Cubic Trinomial
D. Polynomial
Answer:
C) Cubic Trinomial
Step-by-step explanation:
First, we combine like terms to simplify the polynomial. Like terms means having the same variable and exponent.
We get this expression: b^3+4b^2+25
There are 3 terms in this polynomial. Thus, it classifies as a trinomial. And its highest degree is 3, so it’s a cubic trinomial

6x - 5 + 7x = 34 find variable
Answer:
x = 3
Step-by-step explanation:
6x - 5 + 7x = 34
Find x
______________
To solve this, we need to isolate x :
First add like terms :
6x + 7x
13x
13x - 5 = 34
Add 5 to both sides :
13x = 39
Divide 13 from both sides to get x alone :
x = 3
Answer:
x=3
Step-by-step explanation:
Start by moving the 5 over creating 6x+7x=34+5. Then add them together 13x=39. And now simplify x=3

Elena drank 5 bottles of water over 7 volleyball practices. How much water did Elena drink each practice if she drank the same amount each time?
Please have good explanation
Answer:
Step-by-step explanation:
If you would like to know how much water did Elena drink each practice if she drank the same amount each time, you can calculate this using the following steps:
5 bottles of water ... 7 practices
x bottles of water = ? ... 1 practice
5 * 1 = 7 * x
5 = 7 * x /7
x = 5/7 bottle of water
The correct result would be 5/7 bottle of water.

A science class has 5 girls and 7 boys in the seventh grade and 5 girls and 5 boys in the eighth grade. The teacher randomly selects a seventh grader and an
eighth grader from the class for a competition. What is the probability that the students she selects are both boys?
Write your answer as a fraction in simplest form.
We have a total of 10 boys & 8 Girls, then the sample space consist of 18 elements.
P(selecting 1 boy) = (total number of boys/by 18) = P(boy)=10/18=5/9
Jill drove her car for 7 days across the country. She travelled 525 miles. If she continues this pace, how many miles will she have driven after 12 days?
Answer:
900 miles
Step-by-step explanation:
In 7 days she travels 525 miles.
So, in 1 day she travels: 525 ÷ 7 = 75miles
In 12 days she will have driven : 75 × 12 = 900 miles
Step-by-step explanation:
of at 7days Jill drove 525 miles
then she would drive x Miles in 12 days
7d = 525 miles
12 d = (12 ×525)/7
900 miles

9514 1404 393
Answer:
a) -13
b) -22
Step-by-step explanation:
It can be convenient to compute the function values first:
f(1) = 1² -14·1 = -13
g(1) = 1 +8 = 9
Then the compositions are ...
(a) (f+g)(1) = f(1) +g(1) = -13 +9 = -4
(b) (f-g)(1) = f(1) -g(1) = -13 -9 = -22
If the numerator of a fraction is increased by 3, the fraction becomes 3/4.If the denominator is decreased by 7,the fraction becomes 1. Determine the original fraction.
Answer:
9/16
Step-by-step explanation:
Let the original fraction be
x/y
Then
x+3/y=3/4
and
x/y-7=1
Look at 2nd fraction, rearrange it such that you multiply by "y-7" on both sides
x=y-7
Substitute this into 1st fraction:
x-7+3/y=3/4
Now we can solve this for y: cross-multiply --> (Note: y-7+3 = y-4)
4(y-4)=3y
y=16
Sub this back into "x = y-7" to get x
x=16-7=9
Therefore the original fraction is:
9/16

Work out the total interest Adam will get after 5 years.
Answer: 1300 i think
Step-by-step explanation:

Answer:
Correct
Step-by-step explanation:
Just divide both the numerator and the denominator by their common factors.
First of all factor both of the numbers.
405=5*3^4
450=5^2*3^2*2
Now line it up.
5*3*3*3*3
---------------
5*5*3*3*2
Now we can cancel out some numbers and get
3*3
-----
5*5
Now we actually multiplies them again and get.
9/10
This is the process of how to get it hope it helped!

a student earn $16 per day for delivering overnight packages. She is paid $7 per day plus .60 for each package delivered. How many more deliveries mush she must make each day to increase her earnings to $28?
9514 1404 393
Answer:
20 more deliveries
Step-by-step explanation:
The student wants to increase her earnings by $28 - 16 = $12 per day. Her earnings increase by $0.60 per package delivered, so she must deliver ...
$12/($0.60/pkg) = 20 pkgs
more each day.

Find the number that belongs
in the green box.
Round your answer to the nearest tenth.
Answer:
Step-by-step explanation:
The unknown angle.
Start by finding the third angle. Call it x.
x + 125 + 32 = 180
x + 157 = 180
x = 180 - 157
x = 23
Now you are set to use the law of sines.
Call ? = x
x/sin(32) = 7/sin(23) Multiply both sides by Sin(32)
x = 7*sin(32)/sin(23)
x = 7*(0.5299) / sin(23)
x = 3.7094/ sin(23)
x = 3.7094 / 0.3097
x = 9.4935
Rounded to the nearest 10th
x = 9.5
