Baseball hat is on sale for 15% off, which is $2.70. How much does the baseball hat cost at full price?
Answer:
27.9 dollars
Step-by-step explanation:
2.70= 15 percent
2.70x2=5.4=30 percent
5.4+2.70=8.1=45 percent
8.1x2=16.2=95 percent
95 percent + 15 percent=18.9
18.9=105 percent
in order to subtract 5 percent we need to find 5 percent by dividing 2.70 by 3
which = .9
18.9+9=27.9
100 percent is 27.9 dollars

A line passes through the points (0,1) and (13,-3). What is it’s equation in slope intercept form.
[tex]\huge\boxed{y=-\frac{4}{13}+1}[/tex]
First, let's find the slope ([tex]m[/tex]) of the line using the two points:
[tex]\begin{aligned}m&=\frac{y_2-y_1}{x_2-x_1}\\&=\frac{-3-1}{13-0}\\&=\frac{-4}{13}\\&=-\frac{4}{13}\end{aligned}[/tex]
Now, we'll use point-slope form using the first point and the slope to get an equation for the line.
[tex]\begin{aligned}y-y_1&=m(x-x_1)\\y-1&=-\frac{4}{13}(x-0)\end{aligned}[/tex]
Now, we just need to get the equation to slope-intercept form, which is [tex]y=mx+b[/tex].
[tex]\begin{aligned}y-1&=-\frac{4}{13}x\\y&=-\frac{4}{13}x+1\end{aligned}[/tex]

Explain how you could use the information that all circles are similar to show that the value of pi is a constant.
Answer:
defined as the ratio of a circle's circumference to its diameter, is constant. That is, it does not vary given circles of differing size. This claim is equivalent to saying "all circles are proportional" or "all circles are similar."
Answer:
The proof that πk(C1)=πk(C2) of course would just apply the similarity of polygons and the behavior of length and area for changes of scale. This argument does not assume a limit-based theory of length and area, because the theory of length and area for polygons in Euclidean geometry only requires dissections and rigid motions. Any polygonal arc or region can be standardized to an interval or square by a finite number of (area and length preserving). Numerical calculations involving the πk, such as ratios of particular lengths or areas, can be understood either as applying to equidecomposability classes of polygons, or the standardizations. In both interpretations, due to the similitude, the results will be the same for C1 and C2.

Answer:
-11/ -8
Step-by-step explanation:
m= x2-x1 / y2-y1
9-20 / 16-8
-11 / -8
-7y+10x=140
7y+7x=-21
Solve for y
Answer:
-10
Step-by-step explanation:
add these two equations together to get rid of y. This gives you
x = 7
then plug x back into either equation and you can solve for y !

hi please help im so confused, i'm doing an escape room, i have no clue what this means. here is the question also: "Solve for the values of E, F, G, and H, and then input the secret number to unlock this door!"
Answer:
G = 21
H = 9
E = 2
F = 24
Step-by-step explanation:
G
3×(7+10) = 51
51 - 30 = 21
H
15 + 45 = 60
60 ÷ 5 = 12
Adding all these up:
(G) 21 + (H) 9 = 30
2 (E) + 24 (F) = 26
26 + 30 = 56

Our hero, Captain Gravity, is being pulled into a black hole at an acceleration of 20mi/h^2, where x is the distance between his ship and the black hole in miles. Right now he is 300 miles away, but he was not paying attention to his instruments, so he is already moving toward the black hole at 100mi/h. His thrusters give him a constant acceleration of 30mi/h^2 in any direction. Evaluate the following as true or false. Captain Gravity will get sucked into the black hole.
a. True
b. False
Answer:
False
Step-by-step explanation:
Captain Gravity pulls towards the black hole, if his thruster is pointed towards the black hole than the speed will accelerate. In this case the speed will decelerate below from 20 mi/h to 10m/hr. This will reduce the speed and there will be at least 3 hours to stop the movement towards black hole.
What’s the difference? (6d+5)-(2-3d)=
Answer:
9d+3
Step-by-step explanation:
Distribute the Negative Sign:
=6d+5+−1(2−3d)
=6d+5+(−1)(2)+−1(−3d)
=6d+5+−2+3d
Combine Like Terms:
=6d+5+−2+3d
=(6d+3d)+(5+−2)
=9d+3
