Answer:
[tex]1) v= 400 ft^{2}[/tex]
[tex]2) v=1093.3m^{3}[/tex]
Step-by-step explanation:
1) v= 1/3 ab ×h
v= 1/3 (10)(10)×√13²-5²
v= 400 ft²
-------------------
2) v= πr² h/3
v= 1/3 × π×(6)²×29
v= 1/3×π×12×29
v= 348π
v= 1093.27
≈1093.3

If you bought a stock last year for a price of $103, and it has risen 7% since then, how
much is the stock worth now, to the nearest cent?
Answer:
the stock is worth $110.21
Step-by-step explanation:
The first thing you want to do is multiply 0.07 and 103, to find out what 7% of 103 is. When you multiply those two numbers you are going to get 7.21. You are then going to add 103 and 7.21 to find out how much it would be worth now.
Answer:
$110.21
Step-by-step explanation:
well 7% of 103 is 7.21 so if you add that to 103 it = 110.21

Solve for y pls help 10 points
Answer:
y = C/8 + 2
Step-by-step explanation:
C = 8(y - 2)
C = 8y - 16
8y = C + 16
y = C/8 + 2

Answer:
68
Step-by-step explanation:
A soccer ball is kicked from the ground with an initial upward velocity of 90 feet per second. The equation h=-16t^2+90t gives the height h of the ball after t seconds.
a. Find the maximum height of the ball.
b. How many seconds will it take for the ball to reach the ground?
The ball reaches a height of 126.58 ft after 2.8125 seconds
Step-by-step explanation:
The maximum height of a parabola can always be found by looking for the vertex. You can find the x value (or in this case the t value) of a vertex by using -b/2a in which a is the coefficient of x^2 and b is the coefficient of x.
-b/2a
-(90)/2(-16)
-90/-32
2.8125 seconds
Now to find the height, we input that value in for t
h = -16t^2 + 90t
h = -16(2.8125)^2 + 90(2.8125)
126.58 feet
2(3x - 2) = 2(x – 7)
what is the area of the figure below?
Answer:
250
Step-by-step explanation:
You have to find the triangle area and the rectangle and then add them.
Rectangle - 10*20 = 200
Triangle - (10*10)/2 = 50
Area - 200 + 50 = 250

Select the three ratios that represent the numbers of blue marbles to red marbles, there are 6 blue marbles and 9 red marbles
Answer:
6:9 or (2:3)
Step-by-step explanation:
A ratio is a term that gives comparison of values. It helps to determine
how much of a particular thing that is compare to other thing.
Given:
numbers of blue marbles= 6
numbers of red marbles= 9
Hence, ratios that represent the numbers of blue marbles to red = 6:9
We can reduce it using factor of 3, hence the ratio becomes(2:3)

Area- 28.27433, rounded-38.27
Answer:
C≈9.42in
A≈7.07in²
Step-by-step explanation:
C=2πr
d=2r
C=πd=π·3≈9.42478in
A=πr2
d=2r
A=1

IM NOT SMART SUBSTITUTION METHOD AGAIN
Answer:
x = 6
y = -3
Step-by-step explanation:
15x + 31y = -3
we are given that x =( - y + 3 )
so in the equation 15x + 31y = -3 we substitute "x" for ( -y + 3 ) and we solve for y
so 15 ( -y + 3 ) + 31y = -3
now we use basic algebra to solve for y
step 1 distribute the 15
15 * -y = -15y
15 * 3 = 45
now we have 45 - 15y + 31y = -3
step 2 combine like terms
-15 + 31y = 16y
now we have 45 + 16y = -3
step 3 subtract 45 from each side
-3 - 45 = -48
45 - 45 cancels out
now we have 16y = -48
step 4 divide each side by 16
16y/16=y
-48/16=-3
we're left with y = -3
Now to find x we substitute -3 for y in x = -y + 3
* substitute *
x = - ( -3) + 3
the two negative signs cancel out and we get x = 3 + 3
3 + 3 = 6
we're left with x = 6

The Americans with disabilities act sets a maximum angle for a wheelchair ramp entering a business at 4.76 degrees. Determine the horizontal distance needed to accommodate a ramp that goes up to a door.
Answer:
Step-by-step explanation:
tanα=h/d, where α=angle of elevation, h=height, d=horizontal distance.
d=h/tanα, we are given that h=4ft and α=4.76° so
d=4/tan4.76° ft
d≈48.04 ft (to nearest hundredth of a foot)

The height of the right circular cylinder shown below is 10 feet and its base has a radius of 4 feet. A. B. C. D.
Answer:
502.4ft^3
Step-by-step explanation:
Given data
Height= 10ft
radius= 4 ft
Hence the volume for the cylinder can be gotten as
v= πr^2h
v= 3.14*4^2*10
v=3.14*16*10
v=502.4ft^3
Therefore the volume of the cylinder is 502.4ft^3
can you please solve this
