Answer:
sin I = 28 / 35
Step-by-step explanation:
sin I = opposite side / hypotenuse
hyp^2 = 28^2 + 21^2
= 784 + 441
= 1225
hyp = [tex]\sqrt{1225}[/tex]
= 35
sin I = 28 / 35
A student bought a hot dog and juice for $3.75. If she had bought two hot dogs and three juices she would had paid $9.00. Calculate price of a hot dog and a juice
Answer:
hot dog= $2.25
juice= $1.50
Step-by-step explanation:
Let the price of a hot dog be $H and that of a juice be $J.
H +J= 3.75 -----(1)
2H +3J= 9 -----(2)
(1) ×2:
2H +2J= 7.5 -----(3)
(2) -(3):
2H +3J -(2H +2J)= 9 -7.5
Expand:
2H +3J -2H -2J= 1.5
J= 1.5
Substitute J= 1.5 into (1):
H +1.5= 3.75
H= 3.75 -1.5
H= 2.25
∴ The price of a hot dog and a juice is $2.25 and $1.50 respectively.

Select the final image of AABC after the given sequences of transformations. Translate AABC by (4,4),
rotate 90° counterclockwise around A, and reflect over the y-axis.
Answer:
Step-by-step explanation:
given A(-1, 2), B(-3, 4), C(-2, 5)
after translating by (4, 4)
points are A(-1 + 4, 2 + 4), B(-3 + 4, 4 + 4), C(-2 + 4, 5 + 4)
A(3, 6), B(1, 8), C(2, 9)
to rotate 90° counter clockwise (x, y) ----> (-y, x)
now it is rotated around point A(3, 6).That means A remains same and we need to find new coordinates of B and C. To find B and C let us make origin as A and find B ,C coordinates from it.
B'(1 - 3, 8 - 6) = (-2, 2)
C'(2 - 3, 9 - 6) = (-1, 3)
now it becomes (-y, x)
B'(-2, -2)
C'(-3, -1)
now we have to move origin from (3,6) to (0,0) again.
so B'(-2 + 3, -2 + 6) = (1, 4)
C'(-3 + 3 , -1 + 6) = (0, 5)
now reflection over y axis means (x, y) --> (-x, y)
A'(-3, 6)
B'(-1, 4)
C'(0, 5)
it is different from the options
but this is the process, tell me if you find any step different from the question
see the figure below

5 bags of dog food = 18.75 then how much is six bags
Answer:
34.62
Step-by-step explanation:
5 bags of dog food = 18.75
1 bags of dog food = 18.75 / 5 = 5.77
6 bags of dog food
= 6 x 5.77
= 34.62
Answer:
the answer is 22.50$ dollars for 6 bags of dog food.
5 = 6

[tex]\\ \sf\longmapsto 8y-6y=16[/tex]
[tex]\\ \sf\longmapsto 2y=16[/tex]
[tex]\\ \sf\longmapsto y=8[/tex]
Answer:
[tex]y = 8[/tex]
Step-by-step explanation:
If two sides of a triangle is equal the opposite interior angles are also equal.
Therefore,
[tex]6y = 8y - 16 \\ 16 = 8y - 6y \\ 16 = 2y \\ \frac{16}{2} = \frac{2y}{2} \\ 8 \degree = y[/tex]

What is the slope of the line passing through the points (−3, 4) and (2, −1)?
PLEASE HELP ASAP!!!!
Slope:
M = -1
Slope intercept-form:
y = -x + 1
If sin(x) = M, with M > 0, find the value of then sin(x - pi) =
Step-by-step explanation:
sin(x) = M, M > 0
= sin(x - π)
= sin(x)cos(π) - cos(x)sin(π)
= sin(x).(-1) - cos(x).0
= -sin(x) - 0
= -sin(x)
= -M

(Graph is attached for you⤴⤴⤴)
Step-by-step explanation:
Line m ordered pairs = (-4,-32), (2,4),
(5, 22)
Line n ordered pairs = (-5,12), (1,3), (5,-3)
Use this formula⤵⤵⤵
[tex] \frac{y _{2} - y _{1} }{x _{2} - x _{1} } [/tex]
For line m, we'll use (2,4) and (5,22):
22 - 4 = 18
5 - 2 = 3
18 ÷ 3 = 6
Slope of line m = 6
For line n, we'll use (1,3) and (5,-3):
-3 - 3 = -6
5 - 1 = 4
Slope of line n = -6/4 or -3/2
We'll turn all the options to slope-intercept form, so we can tell which has the slopes we need.
A) - Subtract 6x on both sides to get
-y = -6x + 8, then flip all the signs to get y = 6x - 8.
- Subtract 3x on both sides to get 2y = -3x + 9, then divide 2 on both sides to get y = -3/2 x + 9/2.
B)
- Subtract 6x on both sides to get
y = -6x - 8.
- Subtract 3x on both sides to get
-2y = -3x + 9, then divide -2 on both sides to get y = -3/2 x - 9/2.
C)
- Add 6x on both sides to get -y = 6x - 8, then flip all signs to get y = -6x + 8.
- Add 3x on both sides to get 2y = 3x + 9, then divide 2 on both sides to get
y = 3/2 x + 9/2.
D)
- Subtract 6x on both sides to get
-y = -6x - 8, then flip all signs to get
y = 6x + 8.
- Add 3x on both sides to get -2y = 3x + 9, then divide -2 on both sides to get
y = -3/2 x - 9/2.
Hope this helps :)

The graphs below have the same shape. What is the equation of the blue
graph?
Answer:
g(x) = (x - 1)³
Step-by-step explanation:
Given f(x) then f(x + a) is a horizontal translation of f(x)
• If a > 0 then a shift left of a units
• If a < 0 then a shift right of a units
Here g(x) is the graph of f(x) shifted 1 unit to the right , then

On Tuesday at 2 p.m., the ocean’s surface at the beach was at an elevation of 2.2 feet. Winston’s house is at an elevation of 12.1 feet. The elevation of his friend Tammy’s house is times the elevation of Winston’s house.
Part A
How many times greater is the elevation of Winston’s house than the elevation of the ocean’s surface at 2 p.m.?
Part B
What is the elevation of Tammy’s house?
Part C
How many times greater is the elevation of Tammy’s house than the elevation of the ocean’s surface at 2 p.m.?
Part D
On Wednesday at 9 a.m., Winston went diving. Near the beach, the ocean’s surface was at an elevation of -2.5 feet. During his deepest dive, Winston reached an elevation that was times the elevation of the ocean’s surface. What elevation did Winston reach during his dive
Part E
While diving, Winston stopped at a point located halfway between his deepest dive and the ocean’s surface. At what elevation was Winston when he stopped halfway?
Part A.)
12.1 / 2.2 = 5.5
So, the elevation of Winston's house is 5.5 times greater than the elevation of the ocean at 2 p.m.
Part B.)
My apologies if any of the following equations is not the right number, I had looked up the equation for the right number.
12.1 x 3.5 = 42.35
So the elevation of Tammy's house is 42.35.
Part C.)
42.35 / 2.2 = 19.25
the elevation of Tammy's house is 19.25 times greater than the elevation of the ocean.
Part D.)
Had to look for the number again. Next time, could you possibly make sure that all of the numbers are here? It makes it a lot easier.
-2.5 x 20.2 = -50.5
Winston reached an elevation of -50.5 feet.
Part E.)
-50.5 / 2 = -25.25
He had stopped at -25.25.
Again, my apologies if some numbers are incorrect. You did not give them, so I went looking for them.

1. The ratio of children to adults at a swimming pool is 8:3. If there are 40 children at the pool, how many people are at the pool?
Answer:
55
Step-by-step explanation:
You multiply 5 on both sides of the ratio, and you get 40 children : 15 adults. Adding that up, you would get 55 people.
Answer:
Step-by-step explanation:
Write and solve an equation of ratios. The given ratio is 8:3. The number of children is 40 and that of adults is 40 - c. Note that c + (40 - c) = 40.
Solve the following equation of ratios for c: 8 40
---- = ----------
3 a
Cross multiplying, we get 8a = 120, of 15. Then a = number of adults = 24.
Here a = 15 and c = 40. Check the ratio 40/15; does it equal 8/3? YES
The total number of people at the pool is 40 + 24, or 64
