Answer: -$525
Step-by-step explanation:
7x = how many times he withdrew money * how much money he withdrew.
7 * 75 = $525
Francis ended up removing $525 from his bank account, if we assume that he started off with $0- then the change would be -525 dollars.
Superman is working at the Daily Planet Newspaper P(100, 40). He needs to fly to stop a bank robbery at B(40. 80) and then bring the criminals to jail at (130, 105). Finally he needs to fly back to the Daily Planet to get back to work as "Clark Kent'. What is the total distance for the trip?
Given:
Superman is working at Daily Planet Newspaper P(100, 40).
Bank robbery at B(40,80).
Criminals to jail at C(130, 105).
Then fly back to the Daily Planet.
To find:
The total distance for the trip.
Solution:
Distance formula:
[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Using distance formula, the distance between Daily Planet Newspaper P(100, 40) and place of bank robbery at B(40,80) is
[tex]PB=\sqrt{(40-100)^2+(80-40)^2}[/tex]
[tex]PB=\sqrt{(-60)^2+(40)^2}[/tex]
[tex]PB=\sqrt{3600+1600}[/tex]
[tex]PB=\sqrt{5200}[/tex]
[tex]PB=20\sqrt{13}[/tex]
Similarly,
Distance between place of bank robbery at B(40,80) and jail at C(130,105) is
[tex]BC=\sqrt{\left(130-40\right)^2+\left(105-80\right)^2}[/tex]
[tex]BC=5\sqrt{349}[/tex]
Distance between jail at C(130,105) and Daily Planet Newspaper P(100, 40) is
[tex]CP=\sqrt{\left(100-130\right)^2+\left(40-105\right)^2}[/tex]
[tex]CP=5\sqrt{205}[/tex]
Total distance for the trip = PB+ BC +CP
[tex]Trip=2\sqrt{13}+5\sqrt{349}+5\sqrt{205}[/tex]
[tex]Trip=7.2111+93.4077+71.5891[/tex]
[tex]Trip=172.2079[/tex]
[tex]Trip\approx 172.21[/tex]
Therefore, the total distance for the trip is about 172.21 units.
Here is the equation of four straight lines. Two of these lines are parallel. Which two
lines? (3)
Line A y = 2x+3
Line B 2y = 6- 3x
Line C 4x -2y =3
Line D y = 3-2x
Answer:
Line A and Line C are parallel.
Step-by-step explanation:
Find the value of X When 6-3x=5x-10x+6
[tex]6 - 3x = 5x - 10x + 6[/tex]
[tex]6 - x = - 5x + 6[/tex]
[tex]6 + 5x = 6 - 3x[/tex]
[tex]6 = 6 - 3x + 5x[/tex]
[tex]6 = 6 + 2x[/tex]
[tex]2x = 6 - 6[/tex]
[tex]2x = 0[/tex]
Product of two numbers is equal to 0 if at least one of them is 0 . Since 2 is not equal to 0 , x must be equal to 0 .
Which means :-
[tex]x = 0[/tex]
Therefore , the value of x = 0.

How do you write 2x^5-9x^4-2x^2+10 in standard form?
Answer:
[tex]2x^5-9x^4+0x^3-2x^2+0x+10[/tex]
Step-by-step explanation:
A polynomial is in standard form when its terms are ordered from highest to lowest degree.
If the polynomial is missing terms, it must be completed by setting their coefficients to 0.
The given polynomial is:
[tex]2x^5-9x^4-2x^2+10[/tex]
The terms are ordered, but it's incomplete. The terms with exponent 3 and 1 must be included with zero coefficient.
Thus the polynomial in standard form is:
[tex]\boxed{2x^5-9x^4+0x^3-2x^2+0x+10}[/tex]

How can I describe a ordered pair
Answer:
Ordered Pair An ordered pair is a composition of the x coordinate (abscissa) and the y coordinate (ordinate), having two values written in a fixed order within parentheses. It helps to locate a point on the Cartesian plane for better visual comprehension. The numeric values in an ordered pair can be integers or fractions.
Step-by-step explanation:
i hope this helped! :)
Answer:
An ordered pair contains the coordinates of one point in the coordinate system. A point is named by its ordered pair of the form of (x, y). The first number corresponds to the x-coordinate and the second to the y-coordinate. To graph a point, you draw a dot at the coordinates that corresponds to the ordered pair.

To prepare for a bake-off, Dan used 0.68 kilogram of flour each day for 4 weeks. How many grams did Dan use in those 4 weeks? (1 kg = 1,000 g) this question is from Zearn and I've been doing the same one for a week now :3 and no im not in highschool it put that for some reason
Answer:
19040 grams
Step-by-step explanation:
Dan used the amount of flour each day = 0.68 kg
He used the flour for 4 weeks.
So the number of days taken by Dan = 4 × 7 = 28 days
Now amount of flour used in 28 days = Flour used in a day × Number of days
= 0.68 × 28
= 19.04 kg
Since 1 kg = 1000 grams
Therefore, 19.04 kg = 1000 × 19.04 = 19040 grams
Dan used 19040 grams of flour in 4 weeks.
The number of grams of flour that was used is 19040 grams.
Since Dan used 0.68 kilogram of flour each day for 4 weeks, this means that the flours used will be:
= 0.68 × 4
= 2.72kg
Therefore, 2.72kg will be converted to grams and this will be:
= 2.72 × 1000 = 2720 grams
Now, we'll multiply the value by 7 since there are 7 days in a week. This will be:
= 2720 × 7 = 19040
