PLEASE EXTRA POINTS I REALLY NEED HELP!!! 1. A ski lift carries Carol up a slope at a rate of 5 mph.
She skis down the slope, parallel to the lift, at a speed of
20 mph. The round trip takes 45 minutes.
Write and solve a system of equations to determine
how far she skis.
System:
Defined variables:
Solve:
Solution as a sentence:
Hi sorry for the late response, I know the assignment was due at 5pm today but anyway here is the answer.
System:
d= 5(0.75-t)
d= 20t
20t = 3.75 -5t
Define Variables:
d = how far Carol Skied
t = time it took Carol to go up/down
Solve:
20t = 3.75 -5t
20t + 5t = 3.75 -5t + 5t
25t = 3.75
25t/25 = 3.75/25
t = 0.15
Now we plug in the time into the Distances:
20t = 3.75 - 5t
20(0.15) = 3.75 - 5(0.15)
3 = 3.75 - 0.75
3 = 3
Solution as Sentence:
Carol Skied 3 miles
The measure of the exterior angle of the triangle is
Step-by-step explanation:
The sum of two interior angles in a triangle is equal to an exterior angle that's supplementary to the third interior angle
2x - 2 = 45 + x
2x - x = 45 + 2
x = 47°
Answer:
x = 47
Step-by-step explanation:
Finding the third angle (y) of the triangle:
- Since angles on a straight line add up to 180:
2x -2 + y = 180
y = -2x + 2 + 180
= -2x + 182
Hence, the third angle of the triangle is -2x + 182.
Since all 3 angles of a triangle add up to 180°:
-2x + 182 + x + 45 = 180
-2x + x + 227 = 180
-2x + x = 180 - 227
-x = -47
x = 47
Hence, x = 47

what is 1/2(4x+14)=2(x-7)
Answer:
no solution
Step-by-step explanation:
1/2(4x+14)=2(x-7)
Multiply both sides by 2.
4x + 14 = 4(x - 7)
4x + 14 = 4x - 28
Subtract 4x from both sides.
14 = -28
Since 14 = -28 is a false statement, there is no solution for this equation.
Answer: no solution
50 points on god if yall can get this
Step-by-step explanation:
The price of a game discounted by 18% is 0.82x cuz 82% is left
the price of the toy is 1.18x because x + 0.18x
the volume of water is 7/10x because 7/10 is left
the total amount of flour is 13/10x because 10/10x + 3/10x
a sequence is a set of
Answer:
set of related events, movements, or things that follow each other in a particular order.
Step-by-step explanation:
a sequence is an enumerated collection of objects in which repetitions are allowed and order matters. Like a set, it contains members (also called elements, or terms). The number of elements (possibly infinite) is called the length of the sequence.
Jorge gives an equal number of marbles to 6 friends. Which could be the total number of marbles he gave to his friends? (Answer choices 15,33,56,60)
Answer:
D. 60
Step-by-step explanation:
Since the question stated that the number of marbles given out to his 6 friends were equal, we are certain that the total number of marbles is a factor or multiple of 6.
The only other assumption here is the number of marbles given has to be whole number. This means we just have to go through the answer choices and pick the one that is a multiple of 6.
A. 15 - This is wrong as 15 is not a multiple of 6.
B. 33 - This is wrong as 33 is not a multiple of 6.
C. 56 - This is wrong as 56 is not a multiple of 6.
D. 60 - This is CORRECT as 60 is a multiple of 6.
If Jorge gives each of his friends 10 marbles each, it would bring the total number of marbles to be 60.

6 + 4x - 9 what is the awnser
Answer:
y = 5
Step-by-step explanation:
4×(x -3y = -6 ) ➡ 4x - 12y = -24
4x -12y - 4x +9y = 9 - 24 ➡ -3y = -15
y = 5 use this value to find x
x - 3×5 = -6
Most intruments produce notes across ranges called octaves which are made up of 8 notes how many octaves do 51 notes span?
Answer: 51 notes span 6 octaves.
Step-by-step explanation:
The word "octave" is a Latin word that means "eight".
In an instrument, Each octave is made up of 8 musical notes.
If we have 51 notes , the number of octaves can be made in it = [tex]\dfrac{51}{8}[/tex]
[tex]=6.375\approx6\ \ \ \ \ \text{[Rounded to the nearest whole number]}[/tex]
Hence, 51 notes span 6 octaves.

Vanessa wants to determine the perimeter around her garden. She makes an small model of her garden and combines all the sides: 3x + (x + 10) + 5x + (2x + 2). She concludes that the total perimeter of her garden is 56.
Solve the following equation to determine the value of x:
3x + (x + 10) + 5x + (2x + 2) = 56
Answer:
4
Step-by-step explanation:
since it's all addition, we can remove the parentheses
[tex]3x + x + 10 + 5x + 2x + 2 = 56[/tex]
Now we combine like terms
[tex]3x+x+5x+2x+10+2=56[/tex]
[tex]11x+12=56[/tex]
We subtract both sides by 12 to get,
[tex]11x=44[/tex]
now we divide both sides by 11
[tex]x=\frac{44}{11}[/tex]
[tex]x=4[/tex]

OVERDUE PLEASE HELP OR I’LL CRY
Answer:
x = 9
Step-by-step explanation:
combine all the equations and set it equal to 360
10x+ 7 + 88 + 127 + 5x+3 = 360
then combine like terms
15x + 225 = 360
then solve the equation by moving 225 to the right side of the equation
15x = 135
divide both sides by 15
x = 9

Step-by-step explanation:
The side length of a square with an area of 49
Answer:
7
Step-by-step explanation:
A square has 4 sides, all of equal length. We can simply find the square root of the area to find the length and width, or length of each side. So to find the length, you find the square root of the area.
[tex] \sqrt{49} = 7[/tex]
The freshmen competed with the sophomores to see who could raise the most money by recycling. The appropriate design for testing the significance of the difference between the means is
Answer:
Independent-samples t-test.
Step-by-step explanation:
We are looking for the appropriate design for testing the significance of the difference between the means.
Now, there is a parametric test known as the Independent Samples t Test and what this test does is that it compares the mean of two independent groups in order to find out whether there is statistical evidence that the related population mean is significantly different.
Thus, the test to be used here is Independent-samples t-test.

what is the equation of the line
Answer:
y=-x+3.
Step-by-step explanation:
The graph goes down one and right one before making another point. This means that the slope is -1/1. Simplify and you get -1. So far we have y=-1x. -1x is the same as -1. Now we have y=-x. The graph intersects the y-axis at the point (0,3). This makes our y-intercept 3. Our final equation is y=-x+3.
