Step-by-step explanation: you multiply the two equations to get the area.
Answer:
a)[tex](x^{2} +14x+40)ft^{2}[/tex]
b)14ft, 8ft
Step-by-step explanation:
a) Area of Rectangle = Length x Breadth
= [tex](x+10)(x+4)\\=x^{2} +4x+10x+40\\=(x^{2} +14x+40) ft^{2}[/tex]
b) Given Area of rectangle = [tex]112ft^{2}[/tex]
[tex]x^{2} +14x+40=112\\x^{2} +14x-72=0 (Quadratic Equation)\\\\[/tex]
Quadratic Equations: [tex]ax^{2} +bx+c = 0\\[/tex]
In this case, a = 1, b = 14, c = -72
[tex]\frac{-b+/-\sqrt{b^{2}-4ac } }{2a} \\= \frac{-14+/-\sqrt{14^{2} 4(1)(-72)} }{2(1)} \\= 4 or - 18 (reject)[/tex]
We reject negative values.
so x = 4,
The length of table = (x+10) ft = 4+10 = 14ft
The breadth of the table = (x+4) ft = 4 + 4 = 8ft

Three-eighths of the students in a certain class are males and 3/5 of the male
students in the class are accounting majors.
If 1/4 of the female students in the class are accounting majors, what fraction of
the students in the class are NOT accounting majors?
Answer:
3/5 of the students in the class are not in accounting majors
Step-by-step explanation:
The total number of males in the class is 3/8
3/5 of them are accounting majors
The ones who are not in accounting majors are;
3/8 - 3/5 = 9/40
The total number of female students in the class is;
8/8 - 3/8 = 5/8
1/4 of them are accounting majors
The ones who are not in accounting majors are;
5/8 - 1/4 = 3/8
Total number of students not in accounting majors;
9/40 + 3/8
= 24/40
= 3/5

Answer: G.
Step-by-step explanation:
The formula for a circle's circumference is C = 2[tex]\pi r[/tex]
r = radius
We know the rectangle ABCD has a perimeter of 72 cm.
The rectangle is divided into 6 perimeter sides: AP, PB, BC, CQ, QD, and DA.
If we divide 6 sides to the rectangle's perimeter, we can calculate the length of one side.
72 / 6 cm = 12 cm
A side of the perimeter of the rectangle ABCD is equal to 12 cm, which means PQ, the radius of the circle is equal to 12 cm.
C = 2[tex]\pi r[/tex]
radius = 12 cm
C = 2[tex]\pi[/tex] * 12 cm
C = 2 * 12 * Pi cm
C = 24[tex]\pi[/tex]
Answer = G.
Hope I Helped!
Answer:
24pi (G)
Step-by-step explanation:
This question might seem hard at first, but we know one crucial piece of information- line PQ- is the circle's radius. We also know that Q "fits perfectly" on line DC, and that angle QPB is a right angle. Since the line is straight and passes through THE MIDDLe of the rectangle, we can assume that line PQ divides the rectangle into two squares. Since squares have 4 corresponding sides, or sides with the same length, we can rewrite the equation as x+x+2x+2x, which is 6x = 72. Apply and find your answer.
EASIER EXPLANATION:
the radius is at a right angle, meaning it divides the rectangle into two squares.
It is stated that the perimeter of the rectangle is 72, meaning if we write it into an equation where x = short sides and y = long sides.
x+x+y+y = 72
However, the long sides really equal 2x, so we can rewrite the equation
x+x+2x+2x = 72
Simplify
X+x+x+x+x+x = 72
Simplify more
6x = 72
solve
x = 12
We also know that 2x is the dimeter, which is 24.
Apply to the circumference equation
C= Dpi
Since all our answeres are in pi form, we don't need to solve

Then she read a book for 35 minutes.
What time did she finish her swimming lesson and what time did she finish reading
Answer:
She finished swimming lesson at 2:15 p.m.
and reading book at 2:50 p.m.
Step-by-step explanation:
I hope this helped (:
Lola finished her swimming lesson at 2:15 p.m. and read a book at 2:50 p.m.
What are Arithmetic operations?Arithmetic operations can also be specified by adding, subtracting, dividing, and multiplying built-in functions.
Lola's swimming class began at 1:30 p.m. and lasted 45 minutes.
She then spent 35 minutes reading a book.
To determine the time did she finish her swimming lesson and the time did she finish reading.
swimming end time = began time + class duration
swimming end time = 1:30 p.m. + 45 minutes
swimming end time = 2:15 p.m.
reading end time = began time + reading duration
reading end time = 2:15 p.m. + 35 minutes
reading end time = 2:50 p.m.
Thus, she finished her swimming lesson at 2:15 p.m. and read a book at 2:50 p.m.

8th/9th-95 POINTS+BRAINLIEST!!!!!!!! How do you write a quadratic equation in vertex form? Please explain the steps in simple language and use y=x²+6x+16 as an example.
Answer:
In vertex form: y = 1(x - (-3))² + 7
Vertex: Minimum (-3, 7)
Explanation:
Vertex form: y = a(x - h)² + k
Completing square (rules) :
1st rule: (x + d)² = x² + 2dx + d² and (x - d)² = x² - 2dx + d²
2nd rule: x² + 2dx = (x + d)² - d² and x² - 2dx = (x - d)² - d²
Given equation:
y = x² + 6x + 16
y = x² + 2(3)x + 3² + 7
y = (x + 3)² + 7
Into vertex form:
y = 1(x - (-3))² + 7
From this identify:
a = 1, h = -3, k = 7
Solution, vertex of this equation: Minimum (-3, 7)

John works as a part time waiter in a restaurant. He gets a monthly salary of ₹4,410.Calculate John’s daily, weekly and annual salary.(Take 1 month= 30 days)
1 month is aprox. 30 days, so
To find john's daily salary:
For a month, the salary is 4,410 rupees, so for a day how much?
days salary
30 4,410 (This is how I learnt to solve these kind of problems)
1 ?
Then you crisscross the equation which becomes
4,410/30=147 rupees
To find weekly salary:
we now know the salary for one day so we can say: For a day, the salary is 147 rupees, so for 7 days (1 week) how much?
You multiply the salary for one day and the number of days: 147×7=1,029 rupees
To find salary for a year (annual):
we now know the salary for one day so we can say: For a day, the salary is 147 rupees, so for 365 days (1 year) how much?
You multiply the salary for one day and the number of days: 147×365=53,655 rupees

(01.02 HC)Andrew is showing his work in simplifying (−5.7 + 2.2) − 1.1.
Step 1: (2.2 − 5.7) − 1.1
Step 2: 2.2 − (5.7 + 1.1)
Step 3: 2.2 − (6.8)
Step 4: −4.6
Which statement is true?
1. In step one andrew used the commutative property
2. in step 2 andrew used distributive property
3. in step 3 andrew used the associative property
4. In step 4 andrews answer is incorrect
Answer: A
Step-by-step explanation:
Let's fact check all the answer choices:
A. He used the commutative property
Well, the commutative property states that you can put the equation in any order and the result doesn't change. In step1, andrew makes the equation -5.7+2.2 into 2.2-5.7. Both of these equations equal -3.5, so yes, he used the commutative property.
B.He used the distributive property.
We know this is wrong because the distributive property involves multiplication. An Example of an equation that involves the distributive property is 3(2+1), or 3x(2+1).
C. He used the associative property.
This is wrong because the associative property involves grouping the equation into different parentheses , which doesn't happen.
D. The answer is incorrect
Using a calculator , we know this is wrong.

8TH GRADE GEOMETRY:100 POINTS+BRAINLIEST: Please answer the question and explain how you did it. Also, please tell me what a "radii" is. Any absurd answers for the sake of points will be reported thanks :)) !!!
Answer:
Option B 1 : 3
Step-by-step explanation:
Volume formulas & definitions:
To solve this problem, we must remember the formulas for volume of each shape:
[tex]V_{cylinder}=\pi r^2h\\V_{cone}=\frac{1}{3} \pi r^2 h[/tex] where r represents the radius of the circular part of the shape, and h represents the height of the shape (the plural of height is "heights", and the plural of radius is "radii")
So, when the question states that the shapes "have congruent heights and radii" it means that the height of both objects is the same, and the radius of both objects is the same.
Ratios
To find the ratio of the volume of the cone to the volume of the cylinder, we must setup the ratio. Ratios can be setup as a fraction where the first quantity is the numerator (top of fraction), and the second quantity is the denominator (bottom of the fraction):
[tex]\dfrac{V_{cone}}{V_{cylinder}}=\dfrac{\frac{1}{3} \pi r^2 h} {\pi r^2 h}[/tex]
Since the pi, the "r", and the "h" are the same in both the numerator and denominator (and since there is only multiplication & division in the fraction) these common factors can cancel, and reduce the fraction to the following:
[tex]\dfrac{V_{cone}}{V_{cylinder}}=\dfrac{\frac{1}{3}} {1}[/tex]
Any number divided by 1 doesn't change, so one-third divided by 1 is still one-third.
[tex]\dfrac{V_{cone}}{V_{cylinder}}=\frac{1}{3}[/tex]
Other representations of ratios
Lastly, we must remember that a ratio an also be written with a colon symbol, where the numerator is written first, and the denominator is written second.
So, the ratio of the volume of the cone to the volume of the cylinder is:
1 : 3

I WILL GIVE BRIANLIEST FOR FASTEST AND CORRECT ANSER
Answer: C
Step-by-step explanation:
Step 1: Find the unit rate (tomatoes per bowl)
Last time, the ratio was 9:12, or 9 tomatoes for 12 bowls of soup. To finndd the unit ratet, dividde the ffirst given unnit by the 2nd. In this case, tomatoes is the first unit, and bowls is the second. So the unit rate is:
9÷12= 0.75, or 3/4 of a tomato per bowl of soup.
Now, the ratio is 6:8, or 6 tomatoes for 8 bowls of soup. The unit rate is
6÷8= 0.75, or 3/4of a tomato per bowl of soup.
Step 2: Compare
As you can see, the number of tomatoes per bowl of soup hasn't changed at all. So the answer is C.
Hope this helps :)
Answer:
Todays’s soup will taste the same.
Step-by-step explanation:
9 tomatoes for every 12 cups of soup- ratio= 9/12=3/4
6 tomatoes for every 8 cups of soup- ratio=6/8=3/4
They both end in the same ratio, which is 3/4.
Determine whether the given value is a solution to the inequality. Enter yes or no.
8 ≠ 3p + 2; p = 2
Answer: No
Explanation:
Replace p with 2 and simplify
8 ≠ 3p + 2
8 ≠ 3(2) + 2
8 ≠ 6 + 2
8 ≠ 8
We get a false claim, so the original inequality 8 ≠ 3p + 2 is false when p = 2. Meaning that p = 2 is not a solution.
If the "not equal" sign was changed to an equal sign, then we would have a solution.
Answer:
no / false
Step-by-step explanation:
If we set the "p" in this equation to be equal to 2 (p = 2), we can test this inequality:
8 ≠ 3p + 2
8 ≠ 3(2) + 2
8 ≠ 6 + 2
8 ≠ 8
FALSE STATEMENT
so, p = 2 is not a solution to this inequality
(no)
