Find the value of each variable using sine and cosine. Round your answers to the nearest tenth.
Answers
Answer:
x ≈ 9.5 , y ≈ 15.3
Step-by-step explanation:
sin32° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{x}{18}[/tex] ( multiply both sides by 18 )
18 × sin32° = x , then
x ≈ 9.5 ( to the nearest tenth )
cos32° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{y}{18}[/tex] ( multiply both sides by 18 )
18 × cos32° = y , then
y ≈ 15.3 ( to the nearest tenth )

Davindra made a paper box that is 8 in. Long, 5 in. Wide, and 1 in. High. It is shaped like a rectangular prism. What is the surface area of the box? *
Answers
Answer:
106 in²
Step-by-step explanation:
Given that :
Davindra made a paper box that is 8 in. Long, 5 in. Wide, and 1 in. High.
Using the relation :
SA=2lw+2lh+2hw
Surface area :
2(lw + lh + hw)
l = 8 ; w = 5 ; h = 1
Surface area :
2(8*5 + 8*1 + 1*5)
Surface area :
2(40 + 8 + 5)
= 2(53)
= 106 in²
Write an equation that represents the line.

The slope is 3/4 and y intercept is 2
y=3/4x + 2
explanation:
when writing an equation for a linear graph finding the slope, you always wanna use the equation y=mx + b. b represents the y- intercept, m represents the slope.
in this equation the slope is 3/4 and you can find this by finding two “friendly points” which are basically points that are exactly on the in between part between 4 cubes. an example of two friendly points on this graph you can use to find the slope are (0,2) and (4,5). to find the slope using these points, count how many spaces are up and then to the right to get to the point. when writing the slope, the number of spaces up goes on top of the amount of spaces to the side. here it is 3 up and 4 to the side, meaning it will be 3/4.
put it all together you get y= 3/4x +2

X+y=12
Get the y alone, so subtract x by each side to get y= -x+12
Then fill in the equation: 4x + (-x+12)=33, remove the parenthesis and solve to get 3x+12=33. Then subtract 12 from both sides to get 3x=21. Now divide 3x from both sides to get x=7 now, use this x answer for the previous equation, x+y=12. Fill in the x so now it’s (7) + y=12
And then subtract 7 from both sides to get y=5. So for the first slide, x=7 and y=5
For the next slide, you already have y= -x+15. Fill this in for the equation 3x+2y=36. 3x+2(-x+15)=36 distribute to get 3x+-2x+30=36. Subtract the x’s to get an equation of x+30=36. Subtract 30 from both sides to get x=6 and use this for the other equation, y= -x+15 to get y= -6 + 15, which equals y=9. x=6 and y=9
I hope this helped!
Laura and martin obtain a 25 year 160,000 conventional mortgage at 10.5% on a house selling for 190,000. Their monthly payment, including principal and interest, is $1510.40
Answers
Complete question :
Laura and Martin obtain a 30-year, $180,000 conventional mortgage at 10.0% on a house selling for $210,000. Their monthly mortgage payment, including principal and interest, is $1566.00. Determine the total amount they will pay for their house. How much of the cost will be interest? How much of the first payment on the mortgage is applied to the principal?
Answer:
$563760 ; $383760 ; $66
Step-by-step explanation:
Given that:
Monthly mortgage payment = $1566
Period = 30 years
Number of months in period = (30 * 12) = 360
Principal = $180,000
1.)
Total amount paid :
Monthly payment * period
$1566 * 360 = $563760
2.)
Total amount paid = Principal + Interest
Interest = Total amount paid - principal
Interest = $563760 - $180000
Interest = $383760
3)
First payment = 1566
Interest rate = 10% per annum = 0.1 / 12 = 0.0083333
monthly interest: 180,000 * 0.0083333 = 1500
Principal = 1566 - 1500 = $66
