Answer:
y = 12 ; x = 14
Step-by-step explanation:
2x + 7 =3x - 7 { corresponding angles}
7 + 7 = 3x - 2x
14 = x
x = 14
12y + 1 + 3x - 7 = 180 {co interior angles}
12y + 1 + 3 * 14 - 7 = 180
12y + 1 + 42 - 7 = 180
12y + 36 = 180
12y = 180 - 36
12y = 144
y = 12

A checkbook register has a balance of $158 if a deposit of $35 is made and a check for $78.96 is written find the new balance
Final answer:
The new balance in the checkbook register is $114.04.
Explanation:
To find the new balance in a checkbook register after a deposit and a check are processed, you need to add the deposit to the current balance and then subtract the amount of the check.
Initially, the checkbook register has a balance of $158.
A deposit of $35 is made, and a check for $78.96 is written.
Calculating the new balance involves the following steps:
Add the deposit of $35 to the initial balance of $158 to get $193. Subtract the amount of the check, $78.96, from the $193 to find the new balance.After completing these steps, the new balance in the register would be $193 - $78.96 = $114.04.
Balancing your checkbook regularly is essential to manage your money efficiently and to avoid fees associated with overdrafts or insufficient funds.
Every year Aiden uses income from his job to pay for 75% of his college tuition. Next year’s tuition will be $720 more than this year’s, and Aiden will pay $2400. How much is this year’s tuition?
Answer:
$2,480
Step-by-step explanation:
Let $x be next year tuition. Aiden will pay $2,400, that is 75% of $x.
$x - 100%
$2,400 - 75%
Write a proportion:
[tex]\dfrac{x}{2,400}=\dfrac{100}{75}\\ \\75x=2,400\cdot 100\\ \\75x=240,000\\ \\x=3,200[/tex]
Next year’s tuition will be $720 more than this year’s, then this year tuition is
[tex]\$3,200-\$720=\$2,480[/tex]
The ratio of girls to boys at a movie is 3:8. If there are 32 boys, how many girls are at the movie
Answer: 12 girls
Step-by-step explanation: Our first step in this problem is to write down the unit ratio that is involved. In this case, it's girls/boys.
Next, we set up our proportion. We know that at a movie there are 3 girls for every 8 boys so we have 3/8 and we are asked how many girls are at the movie if 32 boys are the movie so that's x/32.
Now we have the proportion 3/8 = x/32.
Notice that the 32 boys must go on the bottom of the second ratio because our unit ratio tells us that we put girls/boys.
Solving from here, we use the means-extremes property to get 3 times 32 to get 96 = 8 times x or 8x. So we have 96 = 8x.
Dividing both sides by 8, we find that 12 = x.
This means that 12 girls are at the movie when 32 boys are at the movie.

Answer:
Question 1:
Draw a line that crosses the largest number of dots. Then use the line to check the best prediction of the number of baseballs that will be used if 275 pitches are thrown.
Question 2:
A). y = 1.2x - 6
Question 3:
J). y = [tex]\frac{9}{4}x - 81[/tex]
Question 4:
F). f(n) = -3n + 24 *Although it doesn't work when f(n) = 6 and n = 6*
Step-by-step explanation:
Question 2:
The line passes throught point (5, 0) and is parallel to the line whose equation is y = 1.2x + 3.8
For parallel lines, their values of slope is the same.
So our line, that passes through point (5, 0), also has a slope of 1.2
Taking another point (x, y) on our line;
Slope = change in y ÷ change in x
1.2 = [tex]\frac{y - 0}{x - 5}[/tex]
y = 1.2x - 1.2(5)
y = 1.2x - 6
Question 3:
The line passes x-axis at point (36, 0)
The line is perpendicular to another line whose equation is y = -[tex]\frac{4}{9}x[/tex] + 5
For perpendicular lines, the product of their slopes = -1
Let's say the slope of our unknown line is a ;
Given: The slope of our second line is -4/9
So,
a × -4/9 = -1
a = -1 × -9/4 = 9/4
Taking another point (x, y) on our unknown line;
Slope = change in y ÷ change in x
9/4 = [tex]\frac{y - 0}{x - 36}[/tex]
Cross-multiplying that you get;
y = [tex]\frac{9}{4}x - 81[/tex]
Question 4:
The function that model that situation is f(n) = -3n + 24 though it doesn't work when f(n) = 6 and n = 6
What is the product?
(-20+5) (58-65)
10 -1004+17025-652
0-1004+ 170452-652
0-1004–7025-652
0-1004 +17025+652
The solution to the given equation (-20+5) (58-65) is 105. This is calculated by first simplifying the expressions within the brackets and then multiplying the resulting numbers.
Explanation:The student's question relates to the calculations and simplifying of expressions in mathematics. This type of operation can be found in basic algebra, and its mastery is an essential part of succeeding in mathematics.

A circle of radius 10 is divided into four congruent sectors. One of these sectors is used to form the curved surface of a cone. What is the volume of this cone?
Answer:
V ≈ 63.4
Step-by-step explanation:
The arc length of the segment becomes the circumference of the cone's base. Therefore, we can find the radius of the cone:
s = C
(90/360) 2π (10) = 2π r
r = 2.5
The radius of the segment is the slant length of the cone. So we can use Pythagorean theorem to find the cone's height.
l² = r² + h²
10² = 2.5² + h²
h = √93.75
The volume of the cone is:
V = π/3 r² h
V = π/3 (2.5)² √93.75
V ≈ 63.4
A stone fell from the top of a cliff into the ocean.
In the air, it had an average speed of 16 m/s. In the water, it had an average speed of 3 m/s before hitting the seabed. The total distance from the top of the cliff to the seabed is 127 meters, and the stone's entire fall took 12 seconds.
How long did the stone fall in the air and how long did it fall in the water?
Time taken by stone in air is 7 seconds and time taken by stone in water is 5 seconds
Solution:
Let "x" represents the time taken by stone in the air
Given that the stone's entire fall took 12 seconds
Thus, the total time taken by it in both air and water = 12 seconds
time taken by stone in the air = x
time taken by stone in water = 12 - x
In the air, it had an average speed of 16 m/s
average speed in air = 16 m/s
We know that,
distance = speed x time
distance covered by it in air = [tex]16 \times x = 16x[/tex]
distance covered in air = 16x
It had an average speed of 3 m/s before hitting the seabed
average speed in water = 3 m/s
distance covered by it in water = [tex]3 \times (12 - x) = 36 - 3x[/tex]
distance covered in water = 36 - 3x
Then,
Total distance covered = distance covered in air + distance covered in water
Total distance covered = 16x + 36 - 3x = 13x + 36
But, the total distance covered by it = 127 meters ( Given )
Therefore,
13x + 36 = 127
13x = 127 - 36
13x = 91
x = 7
Hence, the time taken by stone in air = x seconds = 7 seconds,
And, the time taken by it in water = 12 - x = 12 - 7 = 5 seconds
write an equation for the line perpendicular to y=2x-5 through the point (8,-2)
For this case we have that by definition, the equation of the line of the slope-intersection form is given by:
[tex]y = mx + b[/tex]
Where:
m: It is the slope of the line
b: It is the cut-off point with the y axis
By definition, if two lines are perpendicular then the product of their slopes is -1.
We have the following equation of the line:
[tex]y = 2x-5[/tex]
Then [tex]m_ {1} = 2[/tex]
We find [tex]m_ {2}:[/tex]
[tex]m_ {2} = \frac {-1} {m_ {1}}\\m_ {2} = \frac {-1} {2}\\m_ {2} = - \frac {1} {2}[/tex]
Thus, the perpendicular line will be of the form:
[tex]y = - \frac {1} {2} x + b[/tex]
We substitute the given point and find "b":
[tex]-2 = - \frac {1} {2} (8) + b[/tex]
[tex]-2 = -4 + b\\-2 + 4 = b\\b = 2[/tex]
Finally, the equation is of the form:
[tex]y = - \frac {1} {2} x + 2[/tex]
ANswer:
[tex]y = - \frac {1} {2} x + 2[/tex]

What is the quotient when 4x3 + 2x + 7 is divided by x + 3?
Final answer:
The quotient when 4x^3 + 2x + 7 is divided by x + 3 is 4x^2 - 10x + 32 with a remainder of -89.
Explanation:
To find the quotient when 4x^3 + 2x + 7 is divided by x + 3, we can use long division. Divide the first term, 4x^3, by x which gives 4x^2. Multiply x + 3 by 4x^2 to get 4x^3 + 12x^2. Subtract this from the original expression to get -10x^2 + 2x + 7. Then, divide -10x^2 by x which gives -10x. Multiply x + 3 by -10x to get -10x^2 - 30x. Subtract this from the previous result to get 32x + 7. Finally, divide 32x by x which gives 32. Multiply x + 3 by 32 to get 32x + 96. Subtract this from the previous result to get -89. Therefore, the quotient when 4x^3 + 2x + 7 is divided by x + 3 is 4x^2 - 10x + 32 with a remainder of -89.

A bought a car for Rs.100000 and spent Rs. 10000 on its repairs.He sold this car to B at a gain of 10% who later on sold to Close at a gain of 5%.what did C pay for the car?
Final answer:
C paid Rs. 127,050 for the car.
Explanation:
To find out what C paid for the car, we need to consider the gains made by A and B. A bought the car for Rs.100,000 and spent Rs. 10,000 on repairs. This means A's total cost is Rs. 110,000. A then sells the car to B at a gain of 10%, which means B buys the car for 110% of Rs. 110,000, or Rs. 121,000.
Now, B sells the car to C at a gain of 5%. To find out what C paid, we need to calculate 105% of Rs. 121,000, which gives us Rs. 127,050. Therefore, C paid Rs. 127,050 for the car.

Answer:
x = 65
Step-by-step explanation:
The triangle has 2 congruent sides and is therefore isosceles.
The base angles are congruent, both 25°
Subtract the sum of the base angles from 180° for vertex angle
vertex angle = 180° - (25 + 25)° = 180° - 50° = 130°
Hence x = 130° ÷ 2 = 65

38. Emily is buying some graduation pictures. She pays $25 for the sitting and $15 for each
sheet of pictures she buys. (make a table if it helps)
a. How much does she pay for 5 sheets of pictures?!
b. How much does she pay for "x" sheets?
c. How many sheets can she buy for $145?
a. She pays $100 for 5 sheets
b. 25+15x dollars for x sheets
c. 8 sheets
Step-by-step explanation:
Given
Sitting cost = $25
Per sheet picture cost = $15
Let p be the number of sheets of pictures
Then the cost can be written as a function of p
[tex]c(p) = 25+15p[/tex]
Now,
a. How much does she pay for 5 sheets of pictures?!
Putting p = 5 in the function
[tex]c(5) = 25 + 15(5)\\= 25+75\\=100[/tex]
She will pay $100 for 5 sheets of pictures
b. How much does she pay for "x" sheets?
Putting x in place of p
[tex]c(x) = 25+15x[/tex]
c. How many sheets can she buy for $145?
We know the cost now, we have to find p so,
[tex]145 = 25+15p\\145-25 = 25+15p-25\\120 = 15p[/tex]
Dividing both sides by 15
[tex]\frac{15p}{15} = \frac{120}{15}\\p = 8[/tex]
Hence,
She can buy 8 sheets for $145

Factor by using the difference between two squares
Answer:
see explanation
Step-by-step explanation:
A difference of 2 squares factors in general as
a² - b² = (a - b)(a + b)
(x - 1)² - 25 ← is a difference of squares
with a = x - 1 and b = 5, thus
(x - 1)² - 25
=(x - 1 - 5)(x - 1 + 5) = (x - 6)(x + 4), then
(x - 6)(x + 4) = 0
Equate each factor to zero and solve for x
x - 6 = 0 ⇒ x = 6
x + 4 = 0 ⇒ x = - 4
Solutions are x = - 4, x = 6

How to form an equation?
Determine the known quantities and designate the unknown quantity as a variable while trying to set up or construct a linear equation to fit a real-world application.
In other words, an equation is a set of variables that are constrained through a situation or case.
Suppose the current age of the daughter is D while the mother is M.
As per the given, The daughter is 36 years younger than her mother.
D = M - 36
And , M = 50
D = 50 - 36 = 14
Let's say x year age the mother was 5 times the daughter's age.
(M - x) = 5(D - x)
(50 - x) = 5(14 - x)
50 - x = 70 - 5x
-x + 5x = 70 - 50
