Answer:
Hey there!
We can arrange this to say, "90% of the whole is 126."
Thus, we can write an equation, where w is used as a variable to represent the whole.
0.90w=126
Divide by 0.90
w=140
The whole is 140.

Step-by-step explanation:
Karima, Brenda, Xavier, and Jody are looking for ratios which are equivalent to 4:8 in the columns of the multiplication table below. A multiplication table. Karima says that only the numbers in columns 4 and 8 form equivalent ratios for 4:8. Brenda says that only Karima’s ratios and the numbers in columns 2 and 4 form equivalent ratios for 4:8. Xavier says that Karima’s ratios, Brenda’s ratios, and the numbers in columns 1 and 2 form equivalent ratios for 4:8. Jody says that any pair of columns with even numbers forms equivalent ratios for 4:8. Who is correct? Karima Brenda Xavier Jody
Answer:
Karima is correct
Step-by-step explanation:
4:8 is equal to 4:8. You can put them in the calculator and divide them by 2 and you get the same equal answer. :)
How can I evaluate this when x=1/2 and y= -5
Answer:
Plug in the x and y values
4(1/2)^2 -3(-5)
Apply the exponent so (1/2)^2 or 1/2 • 1/2 which is equal to 1/4
Now you have 4(1/4) -3(-5)
Multiply them out:
4(1/4)=1
-3(-5)=15 [remember a negative times a negative equals a positive]
So now your equation is 1-15
your answer is 1-15= -14

What is 7.5 × 10^18 and 7 × 10^27 plz help ty
7.5 x 10^18: Since the exponent of the scientific notation is positive, move the decimal point 18 places to the right.
AN: 7500000000000000000
7 x 10^27: Since the exponent of the scientific notation is positive, move the decimal point 27 places to the right.
AN: 7000000000000000000000000000
Answer:
7,500,000,000,000,000,000 and 7,000,000,000,000,000,000,000,000,000
Step-by-step explanation:
I would assume that's in scientific notation, so to solve you need to get it out of scientific notation.
Since the exponent is positive, move it that many places to the right.
For the first one, it would be 7,500,000,000,000,000,000.
For the second one, it would be 7,000,000,000,000,000,000,000,000,000.
If the exponent was negative, you would've moved the decimal to the left instead.
Hope this helped. It's the only way I could think of to solve it.

What's 43.396 divided by 57.1? Still confused for this one :(
Answer:
0.76
Step-by-step explanation:
Because this question is requiring you to divide a smaller number by a greater one you are going to have decimals or fractions.
The value of the division of the number 43.396 by 57.1 is 0.76.
What is division?A procedure of dividing anything into equal halves is called division. It is one of the four fundamental operations in math. Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
The given numbers are 43.396 and 57.1. The value of the division will be calculated as below:-
Division = 43.396 / 57.1
Division = 0.76
Therefore, the value of the division of the number 43.396 by 57.1 is 0.76.

Answer:
32
Step-by-step explanation:
Answer:
The answer is C- 2 to 1
Step-by-step explanation:
Please help. Need help
Answer:
C
Step-by-step explanation:
To do this, let's let the decimal equal n. Thus:
[tex]2.\bar1=n[/tex]
There is only one digit repeating, so let's multiply both sides of the equation by 10:
[tex]21.\bar1=10n[/tex]
Now, subtract n from both sides:
[tex]21.\bar1-n=10n-n[/tex]
On the right, it becomes 9n. However, the left, however, expand, the decimal. In other words:
[tex]21.1111...-2.1111...=9n[/tex]
All of the repeating 1s will cancel out. Thus:
[tex]21-2=9n[/tex]
Subtract:
[tex]19=9n[/tex]
Divide both sides by 9:
[tex]n=\frac{19}{9}[/tex]
And since we set the decimal equal to n originally...
[tex]2.\bar1=\frac{19}{9}[/tex]
And we're done!
Notes:
This is the algebraic way to write a repeating decimal into a fraction. You can, of course, always just use a calculator and guess and check.

Step-by-step explanation:
To get it to the simplest ratio all you have to do is put the given numbers (8,2) into fraction form based on the order given in the question. The order given was "squares to circles". This makes squares the numerator and circles the denominator. After you set it into a fraction just reduce the fraction to its simplest form.
.How much force is needed to accelerate a truck with a mass of 2,000 kg, at a rate of 3 m/s²?
The force needed to accelerate a truck with a mass of 2,000 kg, at a rate of 3 m/s² is 6000 Newtons.
What is force?Force is the influence of either pull or pushes in the body. Basically, gravitation forces, nuclear forces, and friction forces are the types of forces. For e.g. when the wall is hit by a hand then a force is exerted by the hand on the wall as well as the wall also exerts a force on the hand. There are different laws given to Newton to understand force.
Given:
The mass of the truck = 2000 kg,
The acceleration of the truck = 3 m/s²,
Calculate the force as shown below,
Force needed for truck = Acceleration of truck × mass of the truck,
Force = 2000 × 3
Force = 6000 N

Step-by-step explanation:
Emma and Ed walk into a room containing 30 assembled Tworks and enough pieces to assemble 100 more Tworks. A Twork takes eight minutes to assemble and 10 minutes to disassemble. If Emma starts assembling Tworks as Ed begins disassembling the ones that were already made, and they both continue to work until there are exactly 35 assembled Tworks in the room (and no partially assembled or disassembled Tworks), how many minutes will Emma have worked?
Answer:
Start with 30 assembled, parts for 100 more.
Each minute results in +1/8 and -1/10
So we want
30 + x/8 - x/10 = 35
x/8 - x/10 = 5
5x - 4x = 200
x = 200 minutes
During 200 minutes, 25 are assembled, 20 are disassembled,
resulting in a net gain of 5, added to the original 30.
Bike ride:
Total distance: 40 km
Desired average speed 20 km/hr
Total time will be 2 hours
20 km at 15 km / hr = 4/3 hour taken
Leaves 2/3 hour for 20 km
20 km in 2/3 hour = 30 km/hr
Gas mileage:
Let m = city mileage
m + 3 = highway mileage
136 / (m+3) + 155 / m = 9
9m^2 - 264m - 465 = 0
m = 31 (discarding negative value)
Bricklaying:
Let b = number of bricks in wall
Lisa lays b/9 bricks per hour
Lauren lays b/10 bricks per hour
b = 5 * (b/9 + b/10 - 10)
b = 5b/9 + 5b/10 - 50
90b = 50b + 45b - 4500
b = 900
Lisa does 100 per hour
Lauren does 90 per hour
Together they do 180 per hour.

Emma will have worked for 200 minutes.
Given, there are 30 assembled T works in the room initially.
A T work takes eight minutes to assemble, so the rate of assembling T work in one minute will be [tex]\frac{1}{8}[/tex].
Similarly, a T work takes 10 minutes to disassemble. so the rate of disassemble of T work will be [tex]\frac{1}{10}[/tex].
Let Emma worked for x min.
According to the question, Emma starts assembling T works as Ed begins disassembling the ones that were already made and they both continue to work until there are exactly 35 assembled T works in the room. So we can write it in equation for form as,
[tex]30+\frac{x}{8} -\frac{x}{10} =35[/tex]
[tex]\frac{x}{8} -\frac{x}{10}=5\\[/tex]
[tex]\frac{5x-4x}{40} =5[/tex]
[tex]x=5\times40[/tex]
