Answers
Abbie takes 110 minutes t complete painting work alone.
How Abbie take 110 minutes to complete painting work alone?Let x= time takes Abbie to paint the room
1 minute =1/x part the of room painted paint by Abbie paint the room
2x minute times takes both to paint the room
so, in 1 minute 1/2x part of the room paint by Abbie and Beth
Abbie paints three times faster than Cathie
Cathie takes 3x minutes take time to paint the room.
in 1 minute 1/3x part of room paint by Cathie
they take 60 minute to paint a room all three working together
in 1minute 1/x+ 1/2x+ 1/3x parts
in 60 minute = ( 1/x+1/2x+ 1/3x) 60 =1 room
= [tex]\frac{6x+3x+2x}{6x^{2} } 60[/tex] = 1

Step-by-step explanation:
since they're both on the same line we must equal them to 180.
18 + x + 4x -3 = 180 (Now you simplify terms)
5x + 15 = 180 (Subtract the 15 from both sides)
5x = 165 (divide by 5 to isolate the variable)

sally runs 5km in 25 minutes. she plans to run in 20 km race. based on the current speed how long will it take her to complete the race?
Answers
Given:
Sally runs 5km in 25 minutes.
Total distance of race = 20 km
To find:
How long will it take her to complete the race?
Solution:
We have,
Time taken by Sally for 5 km = 25 minutes
Time taken by Sally for 1 km = [tex]\dfrac{25}{5}[/tex] minutes
= 5 minutes
Time taken by Sally for 20 km = [tex]20\times 5[/tex] minutes
= 100 minutes
= 1 h 40 minutes [ 1 h = 60 min]
Therefore, the time taken by Sally to complete the race is 1 h 40 minutes.

how many 7-digit numbers are there where all the digits are different and in increasing order? for example, the numbers 1345689 and 2456789 would be counted. (the first digit cannot be zero.) (a) 20 (b) 24 (c) 28 (d) 32 (e) 36
Answers
There are 544,320 7-digit numbers that are all unique and arranged in increasing order.
We apply the Fundamental Counting Principle to this issue. You are aware that a number has seven digits. According to this theory, you must multiply the potential integers for each digit. There are 9 potential numbers if the initial number can't be zero. Consequently, the first digit's value is 9. Any number, but less than 1, could be used for the second digit since it was already used in the first. Thus, 10 – 1 would equal 9. The value in the third digit must be less than 1 and in the second digit. In this case, 9 – 1 Equals 8. And the list goes on.
Therefore, the number of seven-digit numbers in which all digits are different and in increasing order is:
9 × 9 × 8 × 7 × 6 × 5 × 4 = 544,320
Hence, there are 544,320 7-digit numbers with all different digits in increasing order.

Solve the equation :6/x+10=2/15
Answers
Answer:
x = - 45 / 74
Step-by-step explanation:
6 / x + 10 = 2 / 15
6 / x = 2 / 15 - 10
6 / x = 2 / 15 - 150 / 15
6 / x = - 148 / 15
6 = ( - 148 / 15 ) x
6 ( 15 / - 148 ) = x
x = 90 / - 148
x = - 45 / 74
A cylinder trash can is 30in high and has a base radius of 7in. a manufacturer wants to know the surface of this trash can, including the top of the lid.
Answers
The surface area of the given cylinder trash can is 1,628 in²
The surface area of a cylinder is equal to the area of curved surface plus the area of flat surfaces. The flat surfaces are the base and the lid.
Area of the curved surface = 2 π.r.h
Area of the flat surfaces = 2 π.r²
Hence,
Total surface area of a cylinder = 2 π.r.h + 2 π.r²
= 2 π.r (h + r)
Where:
h = height
r = radius of the base
Parameters given:
h = 30 in.
r = 7 in.
Substitute these parameters into the formula:
Area = 2. (22/7) . 7. (7 + 30)

Let f(x) = 5x-7 and g(x) = 2x-3. Find f(x)+g(x)
Answers
Answer:
7x - 10
Step-by-step explanation:
f(x)= 5x - 7
g(x)= 2x - 3
f(x) + g(x)
= 5x - 7 + 2x - 3
= 7x - 10
The sum of f(x) and g(x) is 7x - 10.
To find the sum of f(x) and g(x), you simply need to add the two functions:
f(x) + g(x) = (5x - 7) + (2x - 3)
Now, combine like terms:
f(x) + g(x) = 5x + 2x - 7 - 3
f(x) + g(x) = 7x - 10
Therefore, the sum of f(x) and g(x) is 7x - 10.

Two Grade 7 students, Monique and Matt, both solved the following math problem: If the temperature drops from 7°F to -17°F, by how much did the temperature decrease? The students came up with different answers. Monique said the answer is 24°F, and Matt said the answer is 10°F. Who is correct? Explain, and support your written response with details .
Answers
Answer: It decreased by 24F not 10F because if it were 10F the starting temperature had to be -7F since the difference between this number and -17F is 10F but in this case it starts at 7F so we subtract 7-0=7 and 17-0=17 and add 17+7=24F.
Step-by-step explanation:
7-0=7
17-0=17
17+7=24F
The change in temperature is -24°F.
Monique said the answer of 24°F is true.

The "experimental probability" is the ratio of actual outcomes of interest to the number of trials. It is based on actually performing the selection over and over some number of times. The "theoretical probability" will be the fraction that is the outcomes of interest divided by the total number of possible outcomes.
We note that Mel's purse contains a total of 6 +8 +4 +7 = 25 coins. The theoretical probability of selecting any given coin is then 1/25.

Order of Operations: BPEMDAS
Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to RightEquality Properties
Step-by-step explanation:
Step 1: Define Equation
-4(x + 2) = 4(2 - 2x)
Step 2: Solve for x
Divide -4 on both sides: -(x + 2) = 2 - 2xDistribute negative: -x - 2 = 2 - 2xAdd 2x on both sides: x - 2 = 2Add 2 on both sides: x = 4Step 3: Check
Plug in x into the original equation to verify it's a solution.
Substitute in x: -4(4 + 2) = 4(2 - 2(4))Multiply: -4(4 + 2) = 4(2 - 8)Add/Subtract: -4(6) = 4(-6)Multiply: -24 = -24Here we see that -24 does equal -24.
∴ x = 4 is the solution to the equation.

Answers
The area of the given figure is 100 cm².
In the above figure, we calculate total area by dividing the figure into two sub figures wherein we get a square portion of side 5 cm and a rectangular portion of length 15cm and breadth 5 cm. The area of the square and rectangle can be given as product of their two sides that is length multiplied by breadth.
Area of square portion = 5*5 = 25 square centimeter
Area of rectangular portion =15*5 = 75 square centimeter
Hence total area of the figure = Area of square portion + Area of rectangular portion.
Therefore, Total area of figure = 25 + 75 = 100 cm².
