Answer:
45.27feet
Step-by-step explanation:
Given the height of the balloon (in feet) represented by the equation h=−16t2+28.7t+32.4, where t is the time (in seconds)
Note that the velocity of the balloon at maximum height is zero, hence;
v = dh/dt =0
-32t+28.7 = 0
-32t = -28.7
t = 28.7/32
t = 0.897secs
Get the maximum height
Recall that h=−16t²+28.7t+32.4
h = -16(0.897)²+28.7(0.897)+32.4
h= -12.87+25.74+32.4
h = 45.27feet
Hence the maximum height reached is 45.27feet

Answer:
1314 in²
Step-by-step explanation:
Let l be the length, w be the width and h be the height.
[tex]SA=2(lw+lh+wh)[/tex]
Plug in the given values
[tex]SA=2(17*5+17*26+5*26)\\SA=2(85+442+130)\\SA=2(657)\\SA=1314[/tex]
Therefore, the surface area of the shape is 1314 in².

how to change
a fraction into a percent
Answer:
[see below]
Step-by-step explanation:
If you are given a fraction, convert it into a decimal by diving the numerator by the denominator.
After converting it into a decimal, you multiply it by 100 to get the percent value. After that, you add the percent sign.
Example:
[tex]\text{Convert \frac{5}{10} into a percent.}[/tex][tex]\text{Convert } \frac{5}{10} \text{ into a percent.}\\\\\\\rightarrow \text{Step One: Convert into decimal.}\\\\\frac{5}{10}=0.5\\\\\rightarrow \text{Step Two: Multiply by 100 and then add percent sign.}\\\\0.5 * 100 = 50\\\\[/tex]
50%
[tex]\frac{5}{10}=50[/tex]%
Hope this helps.
Answer:
Divide the numerator into the denominator, then move the decimal 2 places to the right.
Step-by-step explanation:
Let's use 3/4 as an example.
Divide 3 into 4 and you get 0.75
Move the decimal 2 places to the right and you get 75
Then just add a percent sign (75%)

find compound interest on12600rupees for 2years at10% per annum compounded anually
Answer:
₹2520
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 10%/100 = 0.1 per year,
then, solving our equation
I = 12600 × 0.1 × 2 = 2520
I = ₹ 2,520.00
The simple interest accumulated
on a principal of ₹ 12,600.00
at a rate of 10% per year
for 2 years is ₹ 2,520.00.

14 = 3y - 4
Help me pls
Answer:
y = 6
Step-by-step explanation:
I'm going to assume you want to solve for y.
Step 1: Move all constants to 1 side, isolating y and its coefficient:
14 = 3y - 4
14 + 4 = 3y - 4 + 4
18 = 3y
Step 2: Divide both sides by 3 to solve for y:
3y = 18
3y / 3 = 18 / 3
y = 6
Final answer: y = 6

Answer:
A is $60
B is $660
Step-by-step explanation:
For A, you move the decimal in 5% 2 over so it is 0.05. You then multiply 0.05 by 600, multiply that answer by 2, and you'll get $60.
Sorry I'm not sure how to do B, I looked up the answer to that one.

Given the line y =2/3x-3
Write the equation of a line perpendicular to it that passes
through the point (4, -1)
Answer:
y= -3/2x + 5
Step-by-step explanation:
You do the opposite reciprocal of the original equation's slope.
Then you use the new slope from the point (4,-1) on the graph to find the y-intercept. Which is (0,5).
That gets your answer of -3/2x + 5.

-0.75, -7/10, -1/2, 0.50, 3/5
Answer:
-0.75, -7/10, -1/2, 0.50, 3/5
Step-by-step explanation:
put all of them as a decimal first
3/5 = 0.6 (5)
-1/2 = -0.50 (3)
0.50 = 0.50 (4)
-7/10 = -0.70 (2)
-0.75 = -0.75 (1)
i need help hurry!!!!!!!! solve for x
Answer:
Original Equation: 10x-8/3-4x=6x
Add 4x to both sides: 10x-8/3=10x
Subtract 10x from both sides: -8/3=0
However, we know that -8/3 does not equal to 0, so there is no solution.

Find the surface area.

Need this fast
Answer:
920 square feet
Step-by-step explanation:
Top: 20 * 17 = 340
Side triangles: 8 * 15 / 2 = 60
2 side triangles: 60 * 2 = 120
Back rectangle: 8 * 20 = 160
Bottom rectangle: 15 * 20 = 300
All of them: 340 + 120 + 160 + 300 = 920
The surface area is the sum of the area of the two similar triangles and the area of the three rectangles. Then the surface area of the geometry will be 920 square feet.
What is Geometry?It deals with the size of geometry, region, and density of the different forms both 2D and 3D.
The surface area of the geometry will be
The surface area is the sum of the area of the two similar triangles and the area of the three rectangles.
The area of the rectangles will be
Area of rectangles = 8 x 20 + 15 x 20 + 17 x 20
Area of rectangles = 160 + 300 + 340
Area of rectangles = 800 square feet
The area of the triangles will be
Area of triangles = 2 x 1/2 x 15 x 8
Area of triangles = 120 square feet
Then the area of the geometry will be
Area of geometry = 800 + 120
Area of geometry = 920 square feet
