Answer:
320 "if rounded"
Step-by-step explanation: you find out what number times itself equals 6500 which is 80.623 "rounded to 80" then you add up all the sides "80+80+80+80" or "8x4" which would be 320 but you have to do nearest tenth so your answer would be 322.4.

Hank and Lynn are both paying off car loans. • Hank paid $2,000 upfront when he bought his car, and he pays $200 each month. • Lynn did not pay any money upfront when she bought her car, and she pays $275 each month. Is the relationship between the number of months and the total amount paid proportionally for both Hank's and Lynn's loans?
Answer:
the linkage between both the number of months and the amount charged is proportional to both loans from Hank and Lynn.
Step-by-step explanation:
The relationship between the number of months and the total cost paid proportionally is shown below:-
Both Hank and Lynn pay off car loans.
When Hank bought his car, he paid $2,000 in advance, and he needs to pay $200 each month.
Thus, forward to x months the total cost paid (C(h)) is
C(h) = 2000 + 200x ... (i)
So, that relationship is proportional, but not proportional directly.
When Lynn purchased her vehicle, she didn't pay any cash immediately front and she needs to pay $275 every month.
So, after x months the total amount paid (C(l)) is
C(l) = 275x ..... (ii)
This is, therefore, a direct proportionality that is also proportional.
Furthermore the linkage between both the number of months and the amount charged is proportional to both loans from Hank and Lynn.
Answer: The relationship between the number of months and the total amount paid for both Hank and Lynn's loans is proportional.

The sides of a rectangle are 8cm and 6cm. What is the length of the diagonal. 12cm 10cm 9cm 7cm
Answer:
10 cm
Step-by-step explanation:
The diagonal d divides the rectangle into 2 right triangles with legs 8 and 6 and hypotenuse d
Using Pythagoras' identity in one of the right triangles, then
d² = 8² + 6² = 64 + 36 = 100 ( take square root of both sides )
d = [tex]\sqrt{100}[/tex] = 10 cm
Answer:
[tex]\huge\boxed{c = 10\ cm}[/tex]
Step-by-step explanation:
Using Pythagorean Theorem
[tex]c^2 = a^2 + b^2[/tex]
Where c is the length of diagonal, a and b are the length of the rest 2 sides
=> [tex]c^2 = 8^2+6^2[/tex]
=> [tex]c^2 = 64 + 26[/tex]
=> [tex]c^2 = 100[/tex]
Taking sqrt on both sides
=> c = 10 cm

Answer:
m∠ABC = 30°Step-by-step explanation:
m∠BAD = 0.5m∠BCD = 0.5•126° = 63°
The angles in quadriteral add to 360°, so:
m∠ABC + m∠BAC + m∠ACD + reflex m∠BCD = 360°
m∠ABC + 63° + 33° + (360° - 126°) = 360°
m∠ABC + 96° - 126° = 0
m∠ABC = 30°
A school choir needs to make T Shirts for its 75 members and has set aside some money in their budget to pay for them. The members of the choir decided to order from a printing company that charges $3 per shirt, plus a $50 fee for each color to be printed on shirts. Which equation represents the relationship between the number of T-shirts orders, the number of colors on shirts and the total cost of the order. D = 3T + 50C D = 3(75) + 50C D = 3(75) + 50 D= 3(75)
Answer:
D = 3(75) + 30CStep-by-step explanation:
If a school choir needs to make T Shirts for its 75 members and the printing company charges $3 per shirt, the total amount paid for shirts without coloured printing will be $3 * 75 = 3(75) ... 1
If the printing company charges $50 fee for each color to be printed on shirts, then the total number of colours on the short will cost $30C.... 2
where C is the total amount of colours on all the shirts.
The equation that will represents the relationship between the number of T-shirts orders, the number of colors on shirts and the total cost of the order will be gotten by taking the sum of equation 1 and 2.
The equation needed will be 3(75) + 30C where C is the total amount of colours on all the shirts ordered.
The current value of a baseball card is 60 times its original value v (in dollars). The baseball card is worth $15. Write and solve an equation to find the original value of the baseball card. Equation: =15 Original value: $
Answer:
0.25
Step-by-step explanation:
From the information given, you can say that the current value of a baseball card is equal to 60 multiplied for its original value and the equation is:
c=60v, where: c is current value and v is original value
Now, you can replace the current value with 15 that is the value of the baseball card and solve for v:
15=60v
v=15/60=0.25
According to this, the original value of the baseball card is 0.25.

A number K is such that when it is divided by 27,30 or 45,the remainder is 3.
Find the smallest possible value of k.
Solution :-
First of all we have to find out the least common multiple of the given three numbers.
27 , 30 and 45
27 = 3 x 3 x 3
30 = 2 x 3 x 5
45 = 3 x 3 x 5
Form these factors we have to find the numbers which are common in all the three .
LCM = 2 x 3 x 3 x 3 x 5 = 270 .
Now 270 is completely divisible but the number which we want leaves 3 as remainder.
So adding 3 in 270 .
→ 273 is the required answer.
The sum of two numbers is 6, their difference is 4, find the two numbers. What is their product?
Help as soon as possible. Thanks <3
Answer:
The two numbers are 5 and 1. Their product is 5
Step-by-step explanation:
x + y = 6 (*)
x - y = 4 (**)
Let (*) + (**)
--> (x+y) + (x-y) = 6 + 4
<=> 2x = 10 <=> x = 5
Substitute x= 5
(*) <=> 5 + y = 6
<=> y=1
Answer: (x,y) = (5,1)
Their product: x.y = 5x1 = 5

7n +9 = -1+6(n+4)
can someone walk me through this please?
Answer:
n = 14
Step-by-step explanation:
7n +9 = -1+6(n+4)
Distribute
7n+9 = -1 +6n+24
Combine like terms
7n +9 = 6n +23
Subtract 6n from each side
7n -6n+9 = 6n-6n +23
n+9 = 23
Subtract 9 from each side
n+9-9=23-9
n = 14

Brainlest to first correct answer1. Which of the following satisfy the requirements of a set? Explain why the
requirements are or are not met.
(a) All the current U.S. Senators from Texas
(b) All the prime divisors of 1987
(c) All the tall people in Mexico
(d) All the prime numbers between 8 and 10
Answer: The sets are:
b and d.
Step-by-step explanation:
A set is a collection of distinct objects, a set must be well defined, and it can contain numbers, people, objects, etc. (sets can contain infinite elements, for example, the set of the real numbers has infinite elements)
A) The current U.S senators from Texas.
Ok, the "current U.S senators from Texas" depend on when this is read. For example, the senators of today will not be the same as the senators in 10 years from now.
So the elements of this set today are not the same as the ones in 10 years, then this is not a well defined set.
A weel defined set in this case, would be:
"The U.S senators from Texas for the year 2020"
So this is a set of numbers, we know that 1987 is a prime number, so the only prime number that divides 1987 is 1987.
Then this set is {1987}
is well defined.
c) All the people in Mexico.
A person is well defined.
So when i say "all the people in Mexico has for now" we can find all those "elements" and make a set with them.
But the people in Mexico change, so the elements of this set actually depend on when this is read, so this is not well defined.
D) Al the prime numbers between 8 and 10.
Well, we do not have any prime number between 8 and 10, so this is an empty set:
{∅}

A wheelchair ramp is 4.2 meters long. it rises up 7.0 meters. what is the angle of elevation to the nearest tenth of a degree?
=======================================
Work Shown:
I'm assuming your teacher meant to say the ramp is 7 meters long and the ramp rises up 4.2 meters. It doesn't make sense the way they phrased it initially since the ramp must be the longest part (it is the hypotenuse of the right triangle).
See diagram below.
The angle of elevation is the angle made between the ramp and the ground. It's the angle amount the ramp tilts upward.
sin(angle) = opposite/hypotenuse
sin(theta) = 4.2/7
sin(theta) = 0.6
theta = arcsin(0.6)
theta = 36.869897645844
theta = 36.9
Note: inverse sine or [tex]\sin^{-1}[/tex] is the same as arcsine. Make sure your calculator is in degree mode.
