Mayra bought a pair of sneakers. They originally cost $75 but were on sale for 15% how much mony did she save
Answer: $11.25
Step-by-step explanation:
Since the sneakers were on sale for 15% less, the amount she bought them will be:
= (100% - 15%) × $75
= 85% × $75
= 0.85 × $75
= $63.75
Therefore, the amount she saved will then be:
= $75 - $63.75
= $11.25
She saved $11.25

Amanda graphed line m and line n on a coordinate plane, as shown below.
Which of the following statements is true?
A. The slope of line m is greater then the slope of line n
B. The slope of line n is greater than the slope of line m
C. The x-intercept of line m is greater then the x -intercept of line n
D. The y-intercept of line n is greater then the y -intercept of line m.
Answer:
B
Step-by-step explanation:
To find the slope of the line, we do y2-y1/x2-x1. In this case, for line n, I used the points (0,0) and (1,2). This means the slope will be 2-0/1-0. Simplify this to get 2/1 or 2. Therefore the slope for line n is 2.
To find the slope of the line, we do y2-y1/x2-x1. In this case, for line m, I used the points (0,7) and (1,8). This means the slope will be 8-7/1-0. This will make the slope 1/1 or 1. Therefore, the slope for m is 1.
Therefore, the slope for line n is greater than the slope of line m.

find the slope between (-3,2) and (-7,-16)
Answer: The slope between these two is 3.5
Answer:
Solpe=4.5
Step-by-step explanation:
Sorry if I’m wrong, but I think I got it.
So the formula for slope is y2-y1/x2-x1
In (-3,-2) )-7,-16), -3 is x1, -2 is y1, -7 is x2, and -16 is y2.
Now, you need to fill in the formula with these numbers.
-16-2/-7- - 3
-16-2 is -18
-7- - 3 is -4 (two negatives make a positive)
This makes -18/-4. Divide this to get 4.5.

Sally can run 5 km in 25 minutes. At the same rat of speed, how far can she run in 2 hours and five minutes?
Answer:
25 km
Step-by-step explanation:
[tex]\frac{5}{25} :\frac{y}{125}[/tex]
y · 25 = 5 · 125
25y = 625
25y ÷ 25 = 625 ÷ 25
y = 25

The perimeter of a certain square is 4 yards. Find the area of the square in square feet.
Please someone help
Step-by-step explanation:
Write what you know
A square has 4 sides
the perimeter is the sum of the length of all 4 sides
so 4yards / 4 sides = 1 yard per side
we also know a square has all equal sides
that means our area formula will be 1 x 1
Jim was thinking of a number. Jim doubles it, then adds 19 to get an answer of 70.1. What was the original number?
Answer:
25.55
Step-by-step explanation:
Let us take the number he thinked of be x .
On doubling it :-
→ N = 2x
On adding 19 :-
→ N = 2x + 19
According to Question :-
→ 2x + 19 = 70.1
→ 2x = 70.1 - 19
→ 2x = 51.1
→ x = 51.1/2
→ x = 25.55
Hence the required answer is 25.55Help I don’t know how to do this

Answer:
Step-by-step explanation:
Total highlighters = 10
A : favourable cases / total cases = 5/10 = 1/2
B : favourable cases/ total cases * favourable cases/ new total cases
2/10 * 3/9 = 1/5 * 1/3 = 1/15
C : favourable cases/ total cases * favourable cases/ new total cases
5/10 * 4/9 = 1/2 * 4/9 = 4/18
Sin0=20/29 find tan 0
Answer:
Step-by-step explanation:
here opposite =20, hypotenuse=29
to find adjacent use formula
a^2+b^2=c^2
20^2+b^2=29^2
400+b^2=841
b^2=841-400
b=[tex]\sqrt{441\\}[/tex]
b=21
tan theta=opposite/adjacent
=20/21
therefore tan theta =20/21
Answer:
D. tanθ = 20/21
Step-by-step explanation:
Remember that sinθ = opposite/hypotenuse. In this case, since sinθ = 20/29, we are going to say that opposite = 20 and hypotenuse = 29.
To solve for the adjacent side, use the Pythagorean theorem, a^2 + b^2 = c^2.
When you plug in your values and solve for the other leg, you'll get 21.
Now that we know that the adjacent side/other leg is equal to 21, we can find tanθ, since it's equal to opposite/adjacent.
Opposite = 20
Adjacent = 21
tanθ = 20/21
