arleen has a gift card for a local lawn and garden store. she uses the gift card to rent a roller for 4 days. it cost $17 per day to rent the tiller she also buys a rake for $5. find the change to the value of her gift card
Answer:
We use negative values for the money Arleen spends.
a) We determine the change to the value on her gift card:
4(-35)+(-9)= -140+(-9)=-149
b) We determine the amount on money she has left on the gift card after renting the tiller and buying the rake:
200+(-149)=51
Since she has got $51 on her gift card and a wheelbarrow is $50 she is able to buy it:
51>50
RESULT
a) -$149 less b) yes

Answer:
For every 7 small prizes won, there were 3 large prizes won.
ratio : 42:18 or 7:3
As 42/18 is the same as 7/3 For every 7 small prizes won, there were 3 large prizes won.
What are ratio and proportion?A ratio is a comparison between two similar quantities in simplest form.
Proportions are of two types one is the direct proportion in which if one quantity is increased by a constant k the other quantity will also be increased by the same constant k and vice versa.
In the case of inverse proportion if one quantity is increased by a constant k the quantity will decrease by the same constant k and vice versa.
Given, At a certain game at a school carnival, people won 42 small prizes and 18 large prizes.
Now, 42/18 = 21/9 = 7/3.
∴ For every 7 small prizes won, there were 3 large prizes won.

Help me find the slopes of these please.
Slope formula: y2-y1/x2-x1
Part one:
-7-4/-7-(-7)
-11/0
Since the denominator is 0, the slope is undefined.
Part two:
-9-(-9)/2-(-5)
0/7
Since the numerator is 0, the slope is 0.
Best of Luck!
Problem 1
Use the slope formula to get
m = (y2 - y1)/(x2 - x1)
m = (-7 - 4)/(-7 - (-7))
m = (-7 - 4)/(-7 + 7)
m = -11/0
The result is undefined as we cannot divide by zero.
This line is vertical and all vertical lines have undefined slopes. This happens when both points have the same x coordinate.
Answer: Undefined=========================================================
Problem 2
Use the slope formula again, just with different values of course
m = (y2 - y1)/(x2 - x1)
m = (-9 - (-9))/(2 - (-5))
m = (-9 + 9)/(2 + 5)
m = 0/7
m = 0
In contrast to the previous problem, we can have 0 in the numerator. Dividing 0 over any nonzero value leads to 0.
This line is horizontal as both y coordinates are the same value. All horizontal lines have a slope of 0. You can think of it like
slope = rise/run = 0/1
rise = 0 means we don't move up or down
run = 1 means we move to the right 1 unit

Use fundamental identities and/or the complementary angle theorem to find the exact value of the given expression. Do not use a calculator. sec234°−tan234°
Answer:
1Step-by-step explanation:
Given the expression sec²34°−tan²34°, to get the exact value using the fundamental identities and/or the complementary angle theorem, we will apply the trigonometry identity
From sin²θ+cos²θ = 1
Divide both sides of the expression by cos²θ
sin²θ/cos²θ+cos²θ/cos²θ = 1/cos²θ
tan²θ+1 =sec²θ
Since sec²θ= tan²θ+1, hence sec²34°= tan²34°+1... 1
Substituting equation 1 into the expression given in question we will have;
sec²34°−tan²34°
= (tan²34°+1)-tan²34°
collect like terms
= tan²34°-tan²34°+1
= 1
Hence the exact value of the expression sec²34°−tan²34° is 1
find the endpoint of the segment with endpoint (4, 12) and midpoint (-1, 13)
Answer:
(-6,14)
Step-by-step explanation:
We are given one endpoint and the midpoint, so we have to figure out how far apart these two points are:
(4,12) and (-1,13)
First, we take the x values because these two points are using the (x,y) pattern.
How far away are 4 and -1? The answer is 5.
How far away are 12 and 13? Only 1
If we start at the endpoint (4,12) and go to the midpoint at (-1,13), we go 5 to the left. That means we need to go 5 more spaces to the left to get to the other endpoint. The first part of our answer is -6, which is 5 to the left of -1.
Doing the same thing for the y values now, to get from 12 to 13 we go up 1. So we have to go up one more to find the y value of the other endpoint. If you are at 13 and you go up one, you are at 14.

You went to Disney World by car. The trip there took 6 hours. On the way home, people were evacuating for a possible hurricane so your speed decreased by 20 m/hr and it took 10 hours to get home. How fast was the car going on the way there? How fast was it going on the way back home?
Answer:
a) on the way there, the speed = 50 m/hr
b) on the way back home, speed = 30 m/hr
Step-by-step explanation:
[tex]speed (s) = \frac{distance(d)}{time(t)} \\distance = speed\ \times\ time[/tex]
on the way to Disney land:
distance = d
speed = s
time = t = 6 hours
d = s × t
d = s × 6
d = 6s - - - - - (1)
On the way back:
speed decreased by 20m/hr
This means that s₂ = (s - 20)m/hr
time = t₂ = 10 hours
∴ d = s₂ × t₂
d = (s - 20) × 10
d = 10s - 200 - - - - (2)
Note that the distance is the same to and from disney land, therefore, equation (1) equals equation (2)
∴ 6s = 10s - 200
collecting like terms:
10s - 6s = 200
4s = 200
∴ s = 200 ÷ 4
s = 50 m/hr
Therefore on the way there, the car was moving at a apeed of 50m/hr
speed on the way back home (s₂) = (s - 20) m/hr
∴ s₂ = 50 - 20
s₂ = 30 m/hr
Therefore on the way back home the speed was 30 m/hr
Do the ratios 19/8 and 5/4 form a proportion?
============================================================
Explanation:
Your teacher is effectively asking "are the fractions 19/8 and 5/4 equal?"
Let's assume for now that they are. So we have 19/8 = 5/4
To check if that is a true equation, let's cross multiply
19/8 = 5/4
19*4 = 8*5
76 = 40
The last equation is not true, so the first equation is also not true. The ratios are not in proportion.
---------------------------
Alternative method:
Instead of cross multiplying, we can get all the fractions to have the same denominator. The LCD (lowest common denominator) of the two given fractions is 8. Let's turn 5/4 into a fraction with 8 in the denominator.
We'll multiply top and bottom by 2 to get 5/4 turning into 10/8
Now we're asking "are 19/8 and 10/8 the same?" in which the answer is "no they are not the same". The numerators 19 and 10 are different. The fraction 19/8 is larger than 10/8. So 19/8 is larger than 5/4.
---------------------------
2nd Alternative method:
Use your calculator to see that
19/8 = 2.375
5/4 = 1.25
The decimal values should be the same if the fractions were equal, but they are not. This is a very quick way to compare two fractions.

A ball is kicked with an initial height of 0.75 meters and initial upward velocity of 22 meters/second. This inequality represents the time, t, in seconds, when the ball’s height is greater than 10 meters.
Complete Question:
A ball is kicked with an initial height of 0.75 meters and initial upward velocity of 22 meters/second. This inequality represents the time, t in
seconds, when the ball's height is greater than 10 meters.
-4.9t² + 22t + 0.75 > 10
The ball's height is greater than 10 meters when t is approximately between __ and __ seconds
Answer:
The ball's height is greater than 10 meters when t is approximately between 0.47 and 4.02 seconds
Step-by-step explanation:
Given
[tex]-4.9t\² + 22t + 0.75 > 10[/tex]
Required
Solve the inequality
[tex]-4.9t\² + 22t + 0.75 > 10[/tex]
Subtract 10 from both sides
[tex]-4.9t\² + 22t + 0.75 - 10> 10 - 10[/tex]
[tex]-4.9t\² + 22t + -9.25> 0[/tex]
Solve using quadratic formula
[tex]t = \frac{-b \± \sqrt{b^2 - 4ac}}{2a}[/tex]
In this case;
a = -4.9; b = 22; c = -9.25
[tex]t = \frac{-22 \± \sqrt{22^2 - 4 * (-4.9) * (-9.25)}}{2 * -4.9}[/tex]
[tex]t = \frac{-22 \± \sqrt{484 - 181.3}}{-9.8}[/tex]
[tex]t = \frac{22 \± \sqrt{484 - 181.3}}{9.8}[/tex]
[tex]t = \frac{22 \± \sqrt{302.7}}{9.8}[/tex]
[tex]t = \frac{22 \± 17.398}{9.8}[/tex]
Split
[tex]t = \frac{22 + 17.398}{9.8}[/tex] or [tex]t = \frac{22 - 17.398}{9.8}[/tex]
[tex]t = \frac{39.398}{9.8}[/tex] or [tex]t = \frac{4.602}{9.8}[/tex]
[tex]t = 4.02[/tex] or [tex]t = 0.47[/tex]
Convert to inequality;
[tex]0.47 < t < 4.02[/tex]
Hence;
The ball's height is greater than 10 meters when t is approximately between 0.47 and 4.02 seconds

Explanation:
If we know the three side lengths of a triangle, then we can use Heron's formula to get the area
Heron's formula is
[tex]A = \sqrt{S(S-a)(S-b)(S-c)[/tex]
with S being the semiperimeter, or half the perimeter, so [tex]S = \frac{a+b+c}{2}[/tex]. We add up all three sides and divide by 2.
----------------
The smaller triangle has side lengths of a = 19, b = 40, c = 41. So we get a semiperimeter of S = (a+b+c)/2 = (19+40+41)/2 = 50
Plug this along with the a,b,c values to get an area of...
[tex]A = \sqrt{S(S-a)(S-b)(S-c)}\\\\A = \sqrt{50(50-19)(50-40)(50-41)}\\\\A = \sqrt{139500}\\\\A \approx 373.496987939661\\\\[/tex]
which is approximate
-----------------
Do the same for the larger triangle as well
S = (a+b+c)/2 = (19+180+181)/2 = 190
[tex]A = \sqrt{S(S-a)(S-b)(S-c)}\\\\A = \sqrt{190(190-19)(190-180)(190-181)}\\\\A = \sqrt{2924100}\\\\A = 1710\\\\[/tex]
Interestingly enough, we get an exact area value this time as opposed to some approximation.
-----------------
The difference between the two results is the area of the shaded region
1710 - 373.496987939661 = 1336.50301206033
This is approximate since the first result was approximate.
