vera está usando su teléfono. Su batería está a 2/5 de capacidad, y esta baja 1/9 cada hora. ¿Cuántas horas durará la batería?
Answer:
3.6 hours
Step-by-step explanation:
The computation of the number of hours will the battery last is given below:
Given that
The capacity of her battery is 2 by 5
And, it declines 1 by 9 for every hour
So,
[tex]= \frac{2}{5}\times \frac{9}{1}\\\\= \frac{18}{5}\\\\= 3\frac{3}{5}[/tex]
= 3.6 hours

1)
Fact :: Reason
∠DCE = 90° :: sin ∠EDC = sin 30° = 1/2 = 8/16 = CE/DE
∠ACB = 90° :: ∠DCE and ∠ACB are vertical angles
∠ABC = 60° :: 180 - ∠CAB - ∠ACB = 60°
∠CED = 60° :: 180 - ∠EDC - ∠DCE = 60°
△CDE ⁓ △ABC :: Same angles (AAA)
2)
Let's solve for AB
sin 30° = 1/2
sin 30° = BC/AB = 15/AB
1/2 = 15/AB ⇒ AB = 30
AB = 30 in
Let's solve for AC (using another way)
AC/12 = 15/8
AC = 12 * 15 / 8 = 22.5
AC = 22.5 in

Stella had 30 minutes to do a three-problem quiz. She spent 9 7/10
minutes on question A and 5 2/5 minutes on question B. How much time did she have left for question C?
Answer: 14 9/10 mins left
Step-by-step explanation: 9 7/10 + 5 2/5 five and two fifths=5 4/10 9+5=14
7/10+4/10=1 1/10 1 1/10+14=15 1/10 30-15 1/10=14 minutes and 54 seconds
3/5 1/2 3/4 8/10 from least to greatest

Step-by-step explanation:1/2 is greater than the other numbers
Answer:
1/2, 3/5, 3/4, 8/10
Step-by-step explanation:
1/2 in decimal form is 0.5
3/5 in decimal form is 0.6
3/4 in decimal from is 0.75
8/10 in decimal form is 0.8
write the equation of the line that passes through the given point and has the given slope.
(4,2) slope=3
Write the slope-intercept form of the equation of the line.
slope = -10, y-intercept = 5
Write the slope-intercept form of the equation of the line.
through: (-5,-1), slope = 2/5
Write the slope-intercept form of the equation of the line.
through: (5,0) and (-5,2)
Write the slope-intercept form of the equation of the line.
through: (-5,0), parallel to y = -x + 2
1
Write the slope-intercept form of the equation of the line.
through: (4,1), perpendicular to y = -2x + 5
Answer:
y = -10x + 5 and y = 2/5x + 1
Step-by-step explanation:
slope-intercept form is y = mx + b, where m = slope and b = y-intercept.
for your first problem, just plug in the m and b values to complete the equation.
1.) y = mx + b ⇒ y = -10x + 5
plug in -10 for x (slope) and 5 for b (y-intercept)
and for the second problem...
since you're given a value for slope as well as a coordinate pair, all you need to do is plug those values into the equation for their respective variables and then solve for b. (it doesn't matter what order you plug values in, but i'm going to fill them in in the order of the equation; y, m, and x)
1.) plug in -1 for y
y = mx + b ⇒ -1 = mx + b
2.) plug in 2/5 for m
-1 = mx + b ⇒ -1 = 2/5x + b
3.) plug in -5 for x
-1 = 2/5x + b ⇒ -1 = 2/5(-5) + b
now it's time to solve for b! start by multiplying 2/5 and -5.
-1 = 2/5(-5) + b ⇒ -1 = -2 + b
add 2 to both sides of the equation. on the right side, it cancels itself out. on the left side, adding 2 to -1 gives you 1.
and you're left with 1 = b! :)
therefore, y = 2/5x + 1
i hope this helps! have a great day <3

Can someone help. “At the market you can buy 5 bags of apples for $23.60. At the orchard you can get 7 bags of apples for $32.76. Which is the better deal?”
Answer:
7 for $32.76
Step-by-step explanation:
23.60/5 is $4.72
32.76/7 is $4.68
Answer: $4.72
Step-by-step explanation:
To solve this problem we need to find the unit price of a bag of apples(one bag)
Thus, simply do 23.60/5 to get 4.72 and 32.76/7 to get 4.68. Because 4.68 < 4.72, the orchard is a better deal.
Hope it helps <3 :D

i am confused please help
Answer:
3 tiles will not fit together.
Step-by-step explanation:
Measure of an Interior angle of a polygon = [tex]\frac{(n-2)\times 180}{n}[/tex]
Here, n = number of sides of the polygon
Therefore, measure of the interior angles of a regular hexagon,
A = [tex]\frac{(6-2)\times 180}{6}[/tex]
A = 120°
Similarly, interior angle of the regular pentagon,
B = [tex]\frac{(5-2)\times 180}{5}[/tex]
B = 108°
Now m∠A + m∠B + m∠C = 360°
m∠C = 360° - (120° + 108°)
= 132°
To fit the given three tiles perfectly, interior angle (∠D) of the third Octagonal tile should be 132°.
D = [tex]\frac{(8-2)\times 180}{8}[/tex]
D = 135°
m∠C ≠ m∠D
Therefore, 3 tiles will not fit together.

- 12
-41
Answer:
>
Step-by-step explanation:
-12 is closer to 0 than -41 would be therefore -12>-41.
Answer:
>
Step-by-step explanation:
Looking at a number line, -41 is farther from 0 than -12.
See the image below.
The farther left a number is on a number line, the smaller it is.
The farther right a number is on the number line, the larger is it.
So:
-12 > -41
