PLEASE HELP! SO Confused
You and your friend got tricked into helping another friend move stuff from a garage into moving truck. The ramp used is 12 feet long and makes a 36° angle with the horizontal ground. You discover that the incline is just too steep, so you replace the ramp with one that is 32 feet long. What angle does this replacement ramp make with the ground? Round your answer to the nearest tenth of a degree.
Answer:
12.73 Degrees
Step-by-step explanation:
I'm going to assume some things. The height of the truck is not changing, i.e. the distance and length of the ramp are but the height stays the same.
We draw our right triangle, see photo*
We really only care about finding out what side a is so
[tex]c = \frac{a}{sin(A)} \\12 = \frac{a}{sin(36)} \\12sin(36) = a\\a = 7.05342302750\\sin(x) = (\frac{opp}{hyp} )\\sin(x) = (\frac{7.05342302750}{12} )\\= 35.9999 \:degrees[/tex]
So, since I stated that height did not change, the same process just using 32 for the hypotenuse.
[tex]sin(x) = (\frac{opp}{hyp} )\\sin(x) = (\frac{7.05342302750}{32} )\\= 12.73367164 \:degrees[/tex]

A box contains 12 cereal bars. The empty box weighs
1.75 oz. The box and the bars weigh 18.55 oz. what is the weight of each cereal bar?
please answer asap!!!
Answer:
1.4oz
Step-by-step explanation:
You subtract the weight of the box and the bars with the empty box. Then divide the answer you got from that, with 12 and you get your answer.
The weight of each cereal bar is 1.4 oz.
What is an equation?"It is a statement which consists of equal symbol between two mathematical expressions."
For given example,
Let 'x' be the weight of single cereal bar.
A box contains 12 cereal bars.
The empty box weighs 1.75 oz.
The box and the bars weigh 18.55 oz.
This means the the total weight of the box is:
total weight = weight of the empty box + weight of 12 cereal bars
So, we get an equation,
⇒ 18.55 = 1.75 + ('x' × 12)
We solve above equation to find the weight of each cereal bar.
⇒ 18.55 = 1.75 + 12x
⇒ 12x = 16.8
⇒ x = (16.8)/12
⇒ x = 1.4 oz.
Therefore, the weight of each cereal bar is 1.4 oz.

If Wyatt initially invests an amount of $1200 for 4 years at a simple interest of 6.2% and then the amount from that is invested for 5 years at a simple interest of 8%, the new account balance at the end is 2096.64 dollars.
Therefore the answer is $2096.64
What is simple interest?The amount when invested an initial amount of P for n years at annual simple interest rate of r is given by
A = P + Pnr
here, we have,
As Wyatt invest an amount of $1200 at 6.2% simple interest, at the end of 4 years he will have an amount equal to
A = 1200 + 1200×4×0.062
A = 1497.6
Now as Wyatt invest an amount of $1497.6 at 8% simple interest, at the end of 5 years he will have an amount equal to
A = 1497.6 + 1497.6×5×0.08
A = 2096.64

What is the equation of the line that is parallel to y =1/5x+4
and that passes through (5,-4)?
y=-5x-29
y=-5x+21
y=1/5x-4
y=1/5x-5
Answer:
y=(1/5)x-5
Step-by-step explanation:
The given equation is
y=(1/5)x+4
This is of the form
y=mx+b
which is called the slope-intercept form because
m is the slope
b is the y intercept.
In this case,
m=1/5
b=4
you can see from the chart that this matches the red line.
If two lines are parallel, they must have the same slope. So we know that the slope of the desired line is 1/5. So, now we know that
y=(1/5)x+b
Since the line must go through the point (5,-4), we have
-4=(1/5)(5)+b
-4=1+b
b=-5
So, the desired line is
y=(1/5)x-5

a table is 6 feet long and 3 feet wide. you extend the table by inserting two identical table/leaves. the longest side length of each rectangle leaf is 3 feet. the extended table is rectangular with an area of (18+6x) square feet. a: complete the diagram of the table and leaves. b: write an expression in simplest form that represents the length (in feet) of the extended table.
Yep... so they says that the area of the extended leaf is 18+6x... You know that the area is length into breath... here the breath doesn't change.. so it'll be 3ft... can get the length by dividing area by 3... that is 6+2x... Now the new length wil be 2times that plus the previous 6ft length
(c) The line with equation y = 2x +k is a tangent to curve y = 3x² +4. Find the value of k.
Answer:
k = 11/3
Step-by-step explanation:
If the line is tangent to the curve, then Δ = 0.
______________
Remembering:
Δ>0 two different points of intersection x' [tex]\neq[/tex]x''
Δ=0 one point of intersection x' = x''
Δ<0 two different points of intersection in the complex plan x' and -x'
______________
As the line and the curve have one point of intersection, which is (x, y), we can make a equality between them:
2x + k = 3x² + 4
0 = 3x² - 2x + (4 - k)
Now we can use the Δ=0 (Δ= b² - 4ac)
Δ = 0 = (-2)² - 4.3.(4-k)
0 = 4 - 48 + 12k
12k = 44
k = 44/12 = 2 . 22 /3. 2.2 = 22/3.2 = 11/3
k = 11/3
