B

с
0.604
Answer:
A, .54
Step-by-step explanation:
The number line ranges from .542 up until .611, giving you three options below. For .6, it can be translated into .600 which is in bounds of the number line. Next for .604, it is still in bounds of the number line. For .54 it would be translated to .540 which is not in bounds, being before .542.
4 markers cost $7.04. (The photo didn’t load up the first time when I asked the question. It’s a writing proportion question)
9514 1404 393
Answer:
4/7 = $7.04/x
Step-by-step explanation:
You can write the proportion 4 different ways. Any way you write it, you want markers in corresponding positions and prices in corresponding positions.
Here the best choice is ...
(reference quantity)/(different quantity) = (reference price)/(different price)
4/7 = $7.04/x
__
Additional comment
Many people might choose to put the unknown in the numerator:
x/$7.04 = 7/4
or
x/7 = $7.04/4
Answer: None of the above
Step-by-step explanation:
The easiest way to get the cost is to get the cost per unit times the number needed.
x = 7($7.04/4 ) To make that into a proportion it would look like
x/7 = $7.04/4
[tex]\frac{x}{7} =\frac{7.04}{4}[/tex]

A rectangle on a coordinate plane is translated 5 units up and 3 units to the left. Which rule describes the translation?
(x, y) → (x + 5, y – 3)
(x, y) → (x + 5, y + 3)
(x, y) → (x – 3, y + 5)
(x, y) → (x + 3, y + 5)
Answer:
(x, y) → (x – 3, y + 5)
Step-by-step explanation:
If you move up or down, it affects the y coordinate and going up is positive so 5 units up is y + 5 and if moving left or right affects the x coordinate and moving left is negative so x - 3
"5 units up" would be "5 added to the current y-value".
"3 units to the left" would be "3 subtracted from the current x-value".
So, the translation rule is: (x, y) → (x – 3, y + 5)

Answer:
[tex]y=4.5t+20\\\\t=20\\y=4.5*20+20\\y=90+20\\y=110[/tex]
Step-by-step explanation:
So when t=0 in the first equation y=20 which is the length as you are just born. How I calculate 4.5 is that I assume:
y=xt+20
for t=10 we have y=65
65=10x+20
10x=45
x=4.5
the equation becomes y=4.5t+20.

Given: △ABC, D ∈ ray BC
C ∈ BD, AB=AC=BC
Prove: BD>DA>AB
Answer:
BD>DA>AB
Step-by-step explanation:
Since ACB = 60, ACD = 120. Since ACD>ACB then DA is greater than AB. Then we can see that AC + DC has to be greater than DA because of triangle property theorem. That's the same as BC + CD by transitivity and BC + CD is BD by PWP. That means that BD > DA. Since we know that BD > DA, we can say, BD > DA > AB.
Represent 3200 divided by 100 in three different ways and simplify.
The answer of 3200 divided by 100 by three different ways is 32.
What is simplification?
Simplification generally means finding an answer for the complex calculation that may involve numbers on division, multiplication, square roots, cube roots, plus and minus.
Now the given division is, 3200 divided by 100.
Since we know that division can be represented in three different way that is,
a) Factoring
b) Long division
c) Synthetic division
So,
a) Factoring 3200 divided by 100 we get,
(2x2x2x2x2x2x2x5x5)/(2x2x5x5)
= 2x2x2x2x2
= 32
b) Long division 3200 divided by 100
32
100| 3200
- 300
200
- 200
000
So,Quotient is 32
remainder is 0.
c) Synthetic division 3200 divided by 100
Let x = 100
Therefore, 3200 = 32x
now to divide 32x/x syntehtic division is given as,
1 | 32
1
Hence 32x/x by synthetic division we get 32 R 0.
Therefore, the required answer is 32.

Which method for calculating a credit card balance takes into account both
the purchases and the payments made during the current billing cycle?
A. Subsequent Balance Method
B. Previous Balance Method
C. Average Daily Balance Method
D. Adjusted Balance Method
Answer:
The Adjusted Balance Method
Step-by-step explanation:
The Adjusted Balance method calculates finance charges on monies owed at the end of the billing cycle after all transactions, including debits and credits have been posted to the account which include both the purchase and the payment made during the billing cycle.
It usually results in lower finance costs for the consumer because interest is calculated on the final amount instead of day to day.

Which statement is true about y = arctanx?
The domain is (-pi/2,pi/2)
The range is all real numbers.
The graph contains vertical asymptotes.
The graph is symmetric about the origin.
Answer:
D. The graph is symmetric about the origin.
Step-by-step explanation:
got it right on edge :)
The correct option is Option D: The graph is symmetric about origin.
What is the arctan function?The function f(x) = arctan x is the inverse of tangent function y=tanx.
Checking all the options
Option A: This option is incorrect as the domain of arctan x is real number R i.e. (-∞,∞). arctan x is valid for all values of x between -∞ to ∞.
Option B: This option is incorrect as the range of the function arctan x is (-π/2, π/2) which is the restricted domain of the tan x.
Option C: This option is incorrect as the graph is continuous in R and also bounded in (-π/2, π/2) so it has no vertical asymptotes. But tan x has vertical asymptotes.
Option D: This option is correct as from the graph it is also clear that this function arctan x is symmetric about the origin. Also, function arctan x is an odd function. As odd functions are symmetric about origin, arctan x is symmetric about the origin.
Therefore The correct option is Option D: The graph is symmetric about origin.

splits the remaining trail mix evenly among 25 snack bags, how many ounces of trail mix will
each bag have?
ounces
Answer:
3 ounces of trail mix per bag

1 pound = 16 ounces
2 pounds of peanuts
2 pounds of raisins

Mary's house cost $500, 000 in the year 2010.
In 2020 she sold it for $900, 000.
Was the change in price an increase or decrease?
Answer:
Part B
What was the percent of change in the price of the house?
Answer:
Answer:
Part A: It was an increase.
Part B:80%
Step-by-step explanation:
First, state the info of the problem
Cost Price(CP):$500,000
Selling Price(SP):$900,000
Part A Solution
The SP is higher than the CP so there is a price increase
$900,000>$500,000
Part B Solution
Find price change
Price change equals SP-CP
$900,000-$500,000 equal to $400,000
State CP percent so it will later help in finding percent of price change
CP percent:100%(basic percent for the original cost of item,CP percent is basically 100%)
Cross multiply by comparing amount with percent
So if $500,000 equals 100%
∴$400,000 equals ?(can be represented by variable "x")
Cross-multiplying, we get
$500,000x equals 100%×$400,000(dividing both sides by $500,000)
x equals (400/5)% which further equals 80%
∴The percent of change for the house price was 80%
To confirm
If there was a price increase(Profit),the SP equals CP plus P
SP equals 100% plus 80%:180% ∴SP equals 180%
If 100% equals $500,000
∴180% equals x which is $900,000 after cross-multiplying.
Hope all confusion is now cleared.
Please please help me!!!!!
Answer:
x=80
Step-by-step explanation:
This is really simple especially since you have a right triangle, you can easily determine x using trigonometry.
The cosine of an angle in a right triangle is defined by it's adjacent side divided by the hypotenuse.
[tex] \cos(50) = \frac{51}{x} [/tex]
The angle in question is 50, the hypotenuse is the side facing the 90° angle and the adjacent side is the one next to it.
By cross multiplication i can rewrite this as:
[tex]x = \frac{51}{ \cos(50) } [/tex]
[tex]x = \frac{51}{0.64278} [/tex]
[tex]x = 79.34[/tex]
Round to the nearest ten

Find the equation of the line perpendicular to y=−2 that passes through the point (4, −2).
QUICKLY PLEASE
Answer:
x = 4
Step-by-step explanation:
y = - 2 is the equation of a horizontal line parallel to the x- axis.
A perpendicular line is therefore a vertical line parallel to the y- axis with equation
x = c
where c is the value of the x- coordinates the line passes through.
The line passes through (4, - 2 ) with x- coordinate 4 , thus
x = 4 ← equation of perpendicular line

Cherries cost $5.68 a pound. Will $20 be enough to buy a 4.1-pound bag of cherries? Explain how to determine whether $20 is the correct estimate of the product of $5.68(4.1).
Answer: No
Step-by-step explanation:
Cherries costs $5.68 per pound so to find the price of 4.1 pounds, multiply them both together.
$5.68 x 4.1 lb. = $23.3
It costs about $23.3 to purchase 4.1 pounds so you can not buy it with $20.
Answer:
The $20 estimate is too low. $5.68 was incorrectly rounded down; it should have been rounded up to $6. The correct estimate should have been $24, so $20 will not be enough to buy 4.1 pounds of cherries
