write the slope-intercept form of the equation of the line through (4,-5) perpendicular to 6x + 12y=13
Answer:
y=2x-13
Step-by-step explanation:
12y=-6x+13
y=-1/2x+13/2 is the line, so to find the line perpendicular to that, you find that the slope of the line perpendicular to it is 2 because it's the negative reciprocal of -1/2. Then multiply 2 and 4 to get 8 and subtract 13 to get -5. Now you know that -13 is the y-intercept.

In a rectangle diagonal is 5cm ,breadth is 3cm .find the area and perimeter of the rectangle? (STEP BY STEP EXPLANATION)
Answer:
The area of rectangle is 12cm² and the perimeter is 14cm.
Step-by-step explanation:
First, you have to find the length of the rectangle using Pythagoras Theorem :
a² + b² = c²
a² + 3² = 5²
a² = 5² - 3²
a² = 16
a = √16
a = 4 cm
Next, you have to find the perimeter and area of rectangle :
Perimeter = 2(length + breadth)
P = 2(4 + 3)
P = 2(7)
P = 14 cm
Area = length×breadth
A = 4×3
A = 12 cm²
Monica obtained the following results from her mathematics exams: 80,
82, 83, and 91. What score must she get on the next exam so that her
average score is 85
Answer:
89
Step-by-step explanation:
Answer:
A score of 89
Step-by-step explanation:
To find the average, we'll need to add all the results and divide them by the number of her exams. To do this, we'll need to add all her scores and one more (her next score to make the average 85): we'll call that x for now.
(80 + 82 + 83 + 91 + x) ÷ 5 = 85
(336 + x)/5 = 85
Multiply 5 on both sides
336 + x = 425
x = 89
Therefore, Monica will need an 89 on her next test for her average to be 85.

The count in a bacteria culture was 800 after 15 minutes and 1200 after 40 minutes. Assuming the count grows exponentially,
What was the initial size of the culture?
Answer:1) bacteria size = b(initial) * e^(r * t)
initial size = 300
final size = 1600.
Substituting the values into the main equation:
1600 = 300 * e^(r * 35 - 20)
solving for 'r'.
1600 = 300 * e^(r * 15)
1600/300 = e^(r * 15)
taking natural log on both sides to eliminate the power
ln(16/3) = ln[e^(r * 15)]
ln(16/3) = r * 15
r = ln(16/3) / 15
= 0.11159843
= 11.16%
To find the initial bacteria size,
Given: t = 20
300 = b * e^(0.1116 * 20)
Solving for b:
300 = b * e^2.232
b = 300/e^2.232
b = 32

In how many distinguishable ways can you arrange the letters in the word CONNECTICUT? *
Answer:
The number of distinguishable arrangements are 1,663,200.
Step-by-step explanation:
The word is: CONNECTICUT
The number of ways to arrange a word when no conditions are applied is:
[tex]\frac{n!}{k_{1}!\cdot k_{2}!\cdot k_{3}!...\cdot k_{n}!}[/tex]
Here k is the number of times a word is repeated.
In the word CONNECTICUT there are:
3 Cs
2 Ns
2 Ts
And there are a total of n = 11 letters
So, the number of distinguishable arrangements are:
[tex]\frac{n!}{k_{1}!\cdot k_{2}!\cdot k_{3}!...\cdot k_{n}!}=\frac{11!}{3!\times 2!\times 2!}[/tex]
[tex]=\frac{39916800}{6\times 2\times 2}\\\\=1663200[/tex]
Thus, the number of distinguishable arrangements are 1,663,200.

A deli sells sliced meat and cheese. One customer purchases 4 pounds of meat and 5 pounds of cheese for a total of $30.50. A sandwich shop owner comes in and purchases 11 pounds of meat and 14 pounds of cheese for $84.50. The system of equations below represents the situation.
4x + 5y = 30.50
11x + 14y = 84.50
Answer: I think it the second one
Step-by-step explanation:
Answer:
The variable x represents the - cost per pound of meat
The variable y represents the - cost per pound of cheese
The deli charges $4.50 for - a pound of meat

Answer:
a = 102°
b = 78°
c = f = 58°
d = 122°
e = 26°
Step-by-step explanation:
The usual rules apply:
the sum of angles in a triangle is 180°the sum of angles making a right angle is 90°vertical angles are congruentcorresponding angles at a transversal crossing parallel lines are congruentangles of a linear pair are supplementary.__
There are a couple of angles we can find right away:
b corresponds to 78°, so has that measure
a is supplementary to b, so is 180° -78° = 102°
e is complementary to 64°, so is 26°
The unmarked angle between 78° and f is vertical to 44°, so we have ...
78° +44° +f = 180°
f = 58°
Angle c corresponds to angle f, so is 58°
Angle d is supplementary to angle c, so is 180° -58° = 122°
In summary, ...
a = 102°
b = 78°
c = f = 58°
d = 122°
e = 26°

Make up a word problem or scenario that uses the equation 7p+10=24. Make sure to elaborate as much as possible.
Given:
The equation is [tex]7p+10=24[/tex].
To find:
The scenario that uses the given equation.
Solution:
If p is the price of a good. Initial supply of goods at price 0 is 10 and supply increasing by 7 units if the price increased by 1 unit, then at what price the supply will be 24 units.
According to this scenario,
Total supply = 10+7p
Equate total supply with 24, to find the price at which the supply will be 24 units.
[tex]7p+10=24[/tex]
Therefore, the required scenario is "If p is the price of a good. Initial supply of goods at price 0 is 10 and supply increasing by 7 units if the price increased by 1 unit, then at what price the supply will be 24 units."

PLEASE HELP ME!!!
The mystery number is 20 for the given information.
What is Number system?A number system is defined as a system of writing to express numbers.
To find the mystery number, we need to find a number that satisfies all the given conditions:
The GCF of 18, 36, and the mystery number is 2.
The prime factorization of 18 is 2 x 3 x 3.
The prime factorization of 36 is 2 x 2 x 3 x 3.
The only common factor is 2 x 3 x 3, which is equal to 18.
This means that the mystery number must also be divisible by 2.
The mystery number is a multiple of 5.
Since the mystery number is a multiple of 5 and also divisible by 2, it must end in 0 or 5.
The mystery number is greater than 18 and less than 30.
The only number that satisfies all three conditions is 20.
Hence, the mystery number is 20 for the given information.
