Answer:
Step-by-step explanation:
Cross multiply the givens
3b = 4a Divide both sides by 4
3b/4 = a Now divide by b
3/4 = a/b
This can be written as
3:4 :: a:b
You have a square that has a side length of $1$ centimeter. Each minute, $2$ centimeters are added to the side length. After $10$ minutes, what will be the difference between the area of the last square and the area of the initial square in square centimeters (do not include the units in your answer)?
Answer:
Difference in area of the last square and the initial square = 440 cm²
Step-by-step explanation:
Length of the side of a square = 1 cm
Area of the square = (side)² = 1 cm²
Addition of side length every minute = 2 cm
After x minutes length of each side of the square = (1 + 2x) cm
If x = 10 minutes
Length of each side of the square = [1 + 2(10)]
= 21 cm
Area of the square after 10 minutes = (21)²
= 441 cm²
Therefore, difference in area of the last square and area of the initial square
= 441 - 1
= 440 cm²

what is the slope for (4.6) and (8,4
Answer:
This is a vertical line; there is no change in the x coordinate value; and since the slope is defined to be change in y any attempt to corresponding change in x evaluate the slope would result in an attempt ot divide by zero.
Step-by-step explanation:
There your answer hope it helps.
find the angle which y= equals to root 3 x -4 makes with yaxis
9514 1404 393
Answer:
30°
Step-by-step explanation:
The angle a line makes with the x-axis is arctan(slope). Here, that is ...
angle with x-axis = arctan(√3) = 60°
So, the angle made with the y-axis is the complement of this:
angle with y-axis = 90° -60° = 30°
For weeding the garden Arjun was given $18.29 . Now he has $42.38 . How much money did he have before ?

What is the answer to f(1)= ?
Answer:
f(1) = 1
Step-by-step explanation:
To go 1 on the x-axis and check to see where it is on the y-axis. In this case, when x = 1, y = 1.
Therefore, f(1) = 1.
In a batch of lightbulbs, 30% are tinted, if 45 lightbulbs are tinted, how many lightbulbs are in the batch?
Step-by-step explanation:
30% of lightbulbs = 45 lightbulbs
100% of lightbulbs
= 45 * (100/30) = 150 lightbulbs.
Hence there are 150 lightbulbs in the batch.

“Which of the following is most likely caused by chemical weathering” A.cirques carved out by a melting glacier
B. U-shaped valleys formed in a mountain region
C. Rocks and sediment transported and deposited
D.unrecognizable facial features on a marble statue
Answer:
D. Unrecognizable facial features on a marble statue
Step-by-step explanation:
The first 3 answer choices are all examples of physical weathering, not chemical weathering.
This is because the changes were caused by natural things such as flowing water and heating.
However, unrecognizable facial features on a marble statue would be caused by chemical weathering, where chemicals can erode marble and cause distortion in a statue.
So, D is the correct answer.

The third option with the decimal on top as a fraction
Answer:
C
Step-by-step explanation:
Think of the proportional relationship as algebra.
k*number of MovieTickets = Cost, where k is the constant of proportionality.
To find k, you can substitute values in the table and solve for k.
In this example:
k*5 = $28.75
k = $28.75/5
This answer is C.

Sammy has $180 in her savings account and plans to deposit $20 each month.
help me plz
Answer:
For a function f(x) = y.
The independent variable is the one that we chose to input in the function, in this case, is x, and the dependent variable is the variable that changes in response to the independent variable, in this case, is y.
In this problem we have:
"Sammy has $180 in her savings account and plans to deposit $20 each month."
We can define:
y = money in her savings account
x = number of months that have been passed since she started saving.
Originally, she has $180, and she saves $20 per month, so if x months have been passed, the total amount of money in her savings account is:
y = f(x) = $180 + $20*x
Now we want to know if this function is continuous or discrete, to see this we need to look at the possible values of x.
x represents the number of months that have been passed, then the values that x can take are:
x = 0, 1, 2, 3, 4, ...
So x can only take the values of positive integers, this means that the domain of x is discrete, then the function f(x) is a discrete function.

Answer:
C. 350 - acres of pumpkins
Step-by-step explanation:
The Uncle owns 510 acres, and wants 190 more acres of pumpkin than squash totaling at 510.
When looking at the possible answers D is automatically wrong since the Uncle only owns 510 acres. When I added A and C I got 510 as an answer;
160 + 350 = 510
So he wants 190 more pumpkin acres than squash so 160 represents the squash and 350 represents the pumpkin.
160 + 190 = 350
--------------------------------------------------------------------------
Another way to find the answer is by taking 510 and subtracting 190 then dividing by two;
510 - 190 = 320
320 / 2 = 160
160 + 190 = 350
Then 160 would be squash and 350 would be pumpkin.
I hope this helps!

Cady has $3000 to deposit in the bank which offers 4% interest. How long does she need to leave the money in the bank in order to earn $600 in interest?
Answer:
Cady will have to leave the money in the bank for 5 years.
Step-by-step explanation:
Given that Cady has invested $ 3000 in an account with an interest rate of 4%, to know how much time must be invested to obtain $ 600 in interest, the following calculation must be performed:
3000 x 1.04 = 3.120
Thus, each year the investment will yield interest for $ 120. Therefore, since 600/120 is equal to 5, Cady will have to leave the money in the bank for 5 years.

Answer:
380000
Step-by-step explanation:
rounded to the nearest ten thousand
384400 rounded to the nearest ten thousand is 380000.
What is the rounding off numbers?Rounding a number means the process of making a number simpler such that its value remains close to what it was. The result obtained after rounding off a number is less accurate, but easier to use. While rounding a number, we consider the place value of digits in a number.
The given number is 384400.
The number rounded to nearest ten thousand as
380000
Therefore, 384400 rounded to the nearest ten thousand is 380000.
