Answer:
option d is correct
Step-by-step explanation:
taking 28 degree as reference angle . Then
sin 28 = opposite/hypotenuse
sin 28 = 8/17
The value of sin 28° is 8/17.
How to estimate the value of sin 28°?In the right triangle of the figure
Let, x be the opposite side angle of 28°
and y be the hypotenuse
[tex]$\sin \left(28^{\circ}\right)=\frac{x}{y}$[/tex]
We have,
x = 8 units and
y = 17 units
Substitute the values of x and y, we get
[tex]$\sin \left(28^{\circ}\right)=\frac{8}{17}$[/tex]
Therefore, the correct answer is option D. 8/17.

One afternoon the water park sold 525 tickets for a total of $13,545. Child tickets cost $19 each, and adult tickets cost $40 each. How many of each kind of ticket were sold?
Answer:
c = 355 ; a = 170
Step-by-step explanation:
c = children
a = adults
c + a = 525
19c + 40a = 13545
19c + 19a = 9975
19c + 40a = 13545
-21a = - 3570
a = 170
c + 170 = 525
c = 355

A)
y-intercept: (0, 10); vertex: (–2, 2); zeros: none
B)
y-intercept: (0, –10); vertex: (2, –2); zeros: (0,0) and (4,0)

9514 1404 393
Answer:
D) y-intercept: (0, -10); vertex: (2, -2); zeros: none
Step-by-step explanation:
The graph does not cross the x-axis, so there are no real zeros. It crosses the y-axis at (0, -10), so that is the y-intercept.
These observations match choice D.

What is mortgage of a 400000.00 loan at 6% 30 year fixed
9514 1404 393
Answer:
$2398.20
Step-by-step explanation:
Perhaps you want the monthly payment. It is given by the amortization formula ...
A = P(r/n)/(1 -(1 +r/n)^(-nt))
where P is the principal amount, r is the annual interest rate, n is the number of payments per year, t is the number of years.
Your monthly payment will use P = 400,000; r = 0.06, n = 12, t = 30.
A = $400,000(0.06/12)/(1 -(1 +0.06/12)^(-12·30)) ≈ $2398.20

A woman making $2000 per month has her salary reduced by 20% because of sluggish sales. One year later, after a dramatic improvement in sales, she is given a 30% raise over her reduced salary. Find her salary after the raise. $ per month What percent change is this from the $2000 per month? %
The percent change from the $2000 per month will be 4%.
What is the percentage?The quantity of anything is stated as though it were a fraction of a hundred. A quarter of 100 can be used to express the ratio. Per 100 is what the term percent signifies. The symbol ‘%’ is used to symbolize it.
A woman making $2000 per month has her salary reduced by 20% because of sluggish sales. Then her salary will be
⇒ $2,000 × (1 - 0.20)
⇒ $1,600
One year later, after a dramatic improvement in sales, she is given a 30% raise over her reduced salary. Then her salary will be
⇒ $2,000 × (1 + 0.30)
⇒ $2,080
Then the percent change from the $2000 per month will be
P = [(2080 - 2000) / 2000] × 100
P = (80 / 2000) × 100
P = 0.04 × 100
P = 4%
The percent change from the $2000 per month will be 4%.

145°
Answer:
Ans: 50 degrees.
Step-by-step explanation:
We know, a straight angle is 180 degrees. Also, the sum of the three angles of any triangle is equal to 180 degrees.
So,
(180-85) = 95,
(180-145) = 35,
A = (180-95-35) = 50.

max stores his paintbrushes in a box shaped like a rectangular prism. he can fill the bottom of the box with 48 one inch cubes. if the box is 4 inches tall,what is the volume
Answer:
192 inches^3 or 192 cubic inches
Step-by-step explanation:
48 one inch cubes means the base area is 48inches^2. 48inches^2 multiplied by 4 inches = 192inches^3
Answer: 192 square inches
Step-by-step explanation: it says that he can fill the bottom of the box with 48 once inch cubes, and since the cubes are an inch tall, the cubes would cover an inch of the box's height. The box's total height is 4, so you would need to multiply 4 by 48 to get the total number of cubes that can fit in the box, aka the volume of the box.
find the value of x (URGENT/GIVING BRAINLIEST)
Answer:
B)10
Step-by-step explanation:
Because this is a right angle(indicated by the red box) the total measure should be 90°.
And based on that we say 5X +40=90
Subtract 40 from both sides to get 5x=50
And then divide both sides by 5 to get x=10
Answer:
x = 10°
Step-by-step explanation:
5x° + 40° = 90°
5x° = 90°-40°
5x°=50°
x°= 50°/5
x = 10°

mark had 3/2 cans of paint and used 1/2 can for his room. what fraction of the paint did he use
Given:
Mark had [tex]\dfrac{3}{2}[/tex] cans of paint and used [tex]\dfrac{1}{2}[/tex] can for his room.
To find:
The fraction of the paint did he use.
Solution:
Total paint = [tex]\dfrac{3}{2}[/tex] cans
Paint used = [tex]\dfrac{1}{2}[/tex] can
The fraction of the paint did he use is:
[tex]\text{Required fraction}=\dfrac{\text{Paint used}}{\text{Total paint}}[/tex]
[tex]\text{Required fraction}=\dfrac{\dfrac{1}{2}}{\dfrac{3}{2}}[/tex]
[tex]\text{Required fraction}=\dfrac{1}{3}[/tex]
Therefore, Mark use [tex]\dfrac{1}{3}[/tex] of the paint.
What is the slope of the line with points (-3, 2) and (-3, -2)?
Answer:
-4
Step-by-step explanation:
(-3 , 2) = (x1 , y1)
(-3 , -2) = (x2 , y2)
slope (m) = y2 - y1/x2 - x1
=-2-2/-3-(-3)
=-4/-3+3
=-4/0
=-4
Answer:
No slope.
Step-by-step explanation:
We want to find the slope of the line with the points (-3, 2) and (-3, -2).
To find the slope of any line, we can use the slope formula:
[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]
We can let (-3, 2) be (x₁, y₁) and (-3, -2) be (x₂, y₂). Substitute:
[tex]\displaystyle m=\frac{(-2)-(2)}{(-3)-(-3)}[/tex]
Evaluate:
[tex]\displaystyle m=\frac{-2-2}{-3+3}=\frac{-4}{0}[/tex]
Anything divided by zero is undefined.
Therefore, the slope does not exist. The line has no slope.
If you plot the two points and graph the line, you can see that it is a vertical line. If you recall, vertical lines have no slopes.

uppose paired data are collected consisting of, for each person, their weight in pounds and the number of calories burned in 30 minutes of walking on a treadmill at 3.5 mph. How would the value of the correlation coefficient, r, change if all of the weights were converted to kilograms
Answer:
Has no effect on the correlation
Step-by-step explanation:
The correlation coefficient measures the strength of the relationship between two variables and it has no unit of measurement. All that correlation Coefficient does is to observe whether increase in variable x increases as variety able y increases and vice versa and how closely the values in each if the two variables are related. This is to emphasize that, the correlation Coefficient is independent of the unit of measurement of the two variables in question.
Hence, converting all weights to kilograms has no effect on the correlation Coefficient
