Answer:
3c2 + 4c − 15
Step-by-step explanation:
I tried my best if this is correct please sub to m YT I am a aspiring small creator
my YT is YoungGodlyFN.
Applying distributive property, the product of the given expression,
(3c-5)(c+3) is 3c² + 4c - 15.
In mathematics, the outcome of multiplying two integers is their product.
The given expression is,
(3c-5)(c+3)
Expanding this expression as,
3c(c+3) - 5(c+3)
Distribute the number inside the bracket we get,
3c² + 3x3c - 5c - 5x3
⇒ 3c² + 9c - 5c - 15
Combine like terms,
3c² + (9 - 5)c - 15
⇒ 3c² + 4c - 15
Thus,
(3c-5)(c+3) = 3c² + 4c - 15
Hence,
The product of the given expression is 3c² + 4c - 15.

Step-by-step explanation:
Reasoning A cone with radius 6 and height 12 has its radius quadrupled. How many times
greater is the volume of the larger cone than the smaller cone? Use pencil and paper.
Volume of a cone = πr² h/3
r = 6, h = 12
= π × 6² × 12

Speeds of pulleys are inversely proportional to the length of their diameter. Diameter of pulley A is 20 cm. and diameter of pulley B is 10 cm. If B turns at 348 rpm, how fast does pulley A turn?
Answer:
174 rpm
Step-by-step explanation:
The question says that the speed is inversely proportional to the length. Thus, Inverse means, as the diameter increases, the speed reduces, or as the diameter reduces, the speed increases.
Thus, from the question, if diameter A is 20, and B is 10, then definitely, the speed will increase from 348 to a higher rate. Mathematically, we have
20 / 10 = 348 / x, where x is the missing speed.
2 = 348 / x
x = 348 / 2
x = 174 rpm
Therefore, the pulley A must have been running at a speed of 174 rpm

What's 5 similarities about autobiography and biography
Answer:
Step-by-step explanation:
they are both written about a particular individals life
Answer:
A biography, also called a bio, is a non-fiction piece of work giving an objective account of a person’s life. The main difference between a biography vs. an autobiography is that the author of a biography is not the subject.
Biographies include details of key events that shaped the subject’s life, and information about their birthplace, education, work, and relationships. Biographers use a number of research sources, including interviews, letters, diaries, photographs, essays, reference books, and newspapers. While a biography is usually in the written form, it can be produced in other formats such as music composition or film.
Examples of famous biographies include:
His Excellency: George Washington by Joseph J. Ellis
Einstein: The Life and Times by Ronald William Clark
Princess Diana – A Biography of The Princess of Wales by Drew L. Crichton
What is an Autobiography?
An autobiography is the story of a person’s life written by that person. Because the author is also the main character of the story, autobiographies are written in the first person.
The purpose of an autobiography is to portray the life experiences and achievements of the author. Therefore, most autobiographies are written later in the subject’s life.
They often begin during early childhood and chronologically detail key events throughout their life. Autobiographies usually include information about where a person was born and brought up, their education, career, life experiences, the challenges they faced, and their key achievements.
Step-by-step explanation:
A car is traveling down a road at a constant speed of 50 miles per hour. Write an equation that represents the distance traveled by the car, d, for an amount of time, t
Answer:
distance divided by rate = time aka D/R=T
Step-by-step explanation:
this is what i learned at least hope it helps
The equation that represents the distance traveled by the car is equal to d = 50 x t.
Speed calculation
To calculate the speed of an object, it is necessary to relate the distance traveled and the time required to travel that distance, so that:
[tex]V = \frac{d}t}[/tex]
Thus, as we are given the value of a velocity and if we are asked for the expression that represents the distance traveled depending on the time, we have:
[tex]50 miles/hour = \frac{d}{t}[/tex]
[tex]d = 50 \times t[/tex]
So, the equation that represents the distance traveled by the car is equal to d = 50 x t.

Answer:
area = 2184 ft²
Step-by-step explanation:
height² = 60² - 36² = 3600 - 1296 = 2304
height = √2304 = 48
base = 36 + x
x² = 73² - 48² = 5329 - 2304 = 3025
x = √3025 = 55
base = 36 + 55 = 91
area = 1/2(h)(b) = 1/2(48)(91) = 2184 ft²

an administrative assistant at a software company often provides breakfast when there is a morning meeting. for last weeks sales, she purchased 3 dozen doughnuts and 5 dozen croissants, spending a total of $60. in preparation for yesterday's safety meeting, she spent $65 on 4 dozen doughnuts and 5 dozen croissants. assuming she purchased the items at the same bakery both times, how much does a dozen of each cost?
Answer:
donuts: $5.00
croissants: $9.00
Step-by-step explanation:
c - croissants
d - donuts
(1) 3d + 5c = 60
(2) 4d + 5c = 65
solve for 5c in equation (1)
5c = 60 -3d
substitute 5c = 60-3d into (2)
4d + (60 - 3d) = 65
d + 60 = 65
d = 5
to find c substitute d = 5 into (1)
3(5) + 5(c) = 60
15 + 5c = 60
5c = 45
c = 9

Answer:
Option D, The scale of the drawing is 1 inch : 27 inch
Step-by-step explanation:
The complete question is
The floor tiles in the Jackson family’s kitchen are squares that measure 6
3 /4 inches to a side. Each grid square in the drawing measures 1 /4 inch to a side. Which is the scale of the drawing?
A. 1 : 8 3 /4
B. 1 : 10
C. 1 /4 : 27
D. 1 : 27 n
Solution
Given,
Measurement of the tile = 27/4 inches
Side of the drawing = 1/4 inches
The scale of the drawing
1/4 inch of drawing = 27/4 inch of tile
This gives - 1 inch of the drawing = 27 inch of the tile
The scale of the drawing is 1 inch : 27 inch
Hence, option D is correct

Answer:
A. $4594.74
Step-by-step explanation:
To figure this out, use the equation A = P(1 + r/n)^nt. (A is the total principal (P) + interest; r is the decimal form of the annual rate (R), n is the compound, and t is the time in years)
Substitutions added
A = 4000((1 + 0.02/1)^(1(7))
Step 1: We can go on ahead and cancel both the division and multiplication by 1 here.
A = 4000((1 + 0.02)^7)
Step 2: Add 0.02 to 1.
A = 4000(1.02 ^ 7)
Step 3: Find 1.02 to the seventh power. (I rounded it for convenience)
A = 4000(1.14868)
Step 4: Multiply 4000 by 1.14868
A = 4594.74267
Step 5: This is important! Round that answer to the nearest cent.
A = $4594.74, which is A.
In ΔJKL, the measure of ∠L=90°, LK = 12, KJ = 37, and JL = 35. What ratio represents the secant of ∠K?
Answer:
Sec <K = 37/12
Step-by-step explanation:
Given the following measure
∠L=90°
LK = 12
KJ = 37, and
JL = 35.
Considering angle K
JL = opposite
KJ =hypotenuse
LK = adjacent
Using SOH CAH TOA identity
Cos theta = adj/hyp
Cos m<K = LK/KJ
cos m<K = 12/37
Since sec theta = 1/cos thets
Sec <K = 1/cos<K
Sec <K = 1/(12/37)
Sec <K = 37/12
The diameter of the logo at the center of a basketball court is 10 feet. What is the area of the logo?
Answer:
≈78.539816 ft²
≈78.54 ft²
Step-by-step explanation:
Since the logo is in the shape of a circle, the area can be found with the formula:
πr²To find r, divide the diameter of the circle by 2 (r stands for radius, the length from the center of the circle to the edge):
10÷2=5Now that all variables are known, complete the equation to find the area:

1. A rectangle and a triangle have the same area.
The dimensions of the rectangle are 3 cm and 10 cm. The base of the triangle is 6 cm.
What is the height of the triangle? How do you know?
Answer: 30
Step-by-step explanation: I think the height of the triangle is 30 cm because the rectangle has dimensions of 3 cm and 10 cm so I multiplied that which equals 30 then I thought 6 x 5 = 30 so 30 cm
btw, if i'm wrong please don't get mad, i'm trying my best lol
Answer:
H=10
Step-by-step explanation:
First, let's find the area of the rectangle:
L*W
the length is 3 and the height is 10 so substitute and you get:
10*3 = 30
now let's find what the area of the triangle should be:
B*H/2 =30(because the area is the same)
the base is 6 and the height is unknown, now lets fully substitute:
6H/2=30
3H=30
H=10

The Jayden family eats at a restaurant that is having a 15% discount promotion. Their meal costs $78.12 before the discount, and they leave a 20% tip. If the tip applies to the cost of the meal before the discount, what is the total cost of the meal? Round your intermediate calculations and answer to the nearest cent.
Answer:
82.02
Step-by-step explanation:
78.12 x 0.2 = 15.62 tip
78.12 x 0.15 = 11.72 discount
78.12-11.72 = 66.40 discounted meal price
66.40 + 15.62(tip) = 82.02 total meal price
