Step-by-step explanation:

Oatmeal is packaged in a right circular cylindrical container that has a radius of 1.5 inches and a height of 12 inches. What is the surface area of this container in terms of π?

The formula for the surface Area of a cylinder = 2πr( r + h)

r = 1.5 inches

h = 12 inches

Hence,

2 × π × 1.5( 1.5 + 12)

3π(13.5)

= 40.5π square inches

The surface area of the cylinder is

= 40.5π square inches

A prism 11 in tall with a right triangle for a base with side lengths 6 in, 8 in, and 10 in.

A) 344 in2

B) 383 in2

C) 312 in2

D) 288 in2

Answers

Answer:

You may not recognize this...but the base forms a "Pythagorean"  right triangle  with legs  of  6 and 8  cm

The area of a right triangle is  (1/2)  ( product of leg lengths)

So...the area of the base   = (1/2) (6 * 8 ) = (1/2) 48  = 24 cm^2

And the volume of the prism is just the   base area  x  height =   24  x  7  =   192 cm^2

The ratio of girls to boys is 12 girls to 20 boys.
If there are 3 girls, how many boys are there?
There are
boys.
Next Question

Answers

Answer:

5

Step-by-step explanation:

ratio = 12:20

12/4 = 3

so we do

20/4 = 5

there are 5 boys

Another way, we can write it as a fraction

12/20 = 3/x

12x = 60

x = 5

Answer:

5 boys

Step-by-step explanation:

Write it like this:

3/X=12/20

Then, cross multiply.

3*20=60

X*12=12X

12X=60

Divide both sides by 12

60/12=5

X=5

The unknown number is 5

If there are 3 girls, then there are 5 boys.

HELP PLEASE!!

Planes that fly at high speeds and low elevations have radar systems that can determine the range of an obstacle and the angle of elevation to the top of the obstacle. The radar of a plane flying at an altitude of 20,000 feet detects a tower that is 25,000 feet away, with an angle of elevation of 1∘.



a. How many feet must the plane rise to pass over the tower?

The plane must rise at least _____feet to pass over the tower.


Question 2
b. Planes cannot come closer than 1000 feet vertically to any object. At what altitude must the plane fly in order to pass over the tower?

The plane must fly at an altitude of at least ____ feet to pass over the tower.

Answers

Answer:

a. About 436 ft

b. 21,436 feet

Step-by-step explanation:

a. Notice how the plane's rise (h), its horizontal distance from the tower, and its distance to the top of the tower (25,000 ft) all form a right triangle. If we want to find h, we need some way of putting it in an equation with the two quantities we already know: the angle of elevation and the distance to the top.

In the language of right triangles, we want to combine an angle, the side opposite the angle, and the hypotenuse. The sine function is perfect for this, since [tex]\sin{\theta}=opp/hyp[/tex]. For our problem, opp = h, hyp = 25,000, and θ = 1°, so our equation becomes

[tex]\sin{1^\circ}=h/25000[/tex]

or equivalently

[tex]h=25000\sin{1^\circ}\approx436[/tex] ft (rounded up to the nearest whole foot)

b. If the plane is currently flying at 20,000 feet, it needs to rise about 436 feet to clear the top of the tower, and another 1,000 feet to follow safety protocol, making its required altitude 20,000 + 1,000 + 436 = 21,436 feet.

Answers

Answer:

BC ≈ 9.5 mm

Step-by-step explanation:

Since, ΔBAC is a right angle triangle,

By applying Pythagoras theorem in the given right triangle,

(Hypotenuse)² = (Leg 1)² + (Leg 2)²

BC² = AB² + AC²

BC² = 6² + (7.3)²

BC = [tex]\sqrt{89.29}[/tex]

BC =

A leaky valve on the water meter overcharges Ahmed for one Liter of water for every 2 months. The overcharged amount w varies directly with time t . (a) Find the equation that models the variation . (b) Solve the equation to find the number of months it will take for Ahmed to be overcharged for 10 liters of water leaked. Show all your steps

Answers

Answer:

20 months

Step-by-step explanation:

A leaky valve on the water meter overcharges Ahmed for one Liter of water for every [tex]2[/tex] months. The overcharged amount [tex]w[/tex] varies directly with time [tex]t[/tex].

(a)

As the overcharged amount [tex]w[/tex] varies directly with time [tex]t[/tex],

[tex]w=kt[/tex]

Here, [tex]k[/tex] is a constant.

A leaky valve on the water meter overcharges Ahmed for one Liter of water for every [tex]2[/tex] months.

Put [tex]w=1\,,\,t=2[/tex]

[tex]1=2k\\k=\frac{1}{2}[/tex]

So,

[tex]w=\frac{t}{2}[/tex]

(b)

To find the number of months it will take for Ahmed to be overcharged for 10 liters of water leaked, put [tex]w=10[/tex] in [tex]w=\frac{t}{2}[/tex]

[tex]10=\frac{t}{2}\\\\t=10(2)\\[/tex]

[tex]t=20[/tex] months

Based on the problem above, how would you rewrite as a binomial squared?

x^2 + 8x - 3 = 0 (x + __ )^2 = __

Answers

Answer:

the quadratic equation cannot be written as the square of a binomial

Step-by-step explanation:

Given the expression

x^2 + 8x - 3 = 0

On factorizing

x = -8±√8²-4(-3)/2

x = -8±√64+12/2

x = -8±√76/2

x = -8±8.7/2

Note that since the since the discriminant is not a prefect square, the quadratic equation cannot be written as the square of a binomial

Answer: 5/2x-7-3/4x=3/4x+14-3/4x

7/4x-7=14

7/4x-7+7=14+7

7/4x=21

(4/7)*(7/4x)=(4/7)*(21)

x=12

Step-by-step explanation:

Yeh so simpliy it. I you do something to one side, do it to the other.

(5/2)x - 7 = (3/4)x + 14

first get rid of the smallest value of x which is 3/4.

We need to change the denominate for this

(10/4)x -(3/4)x -7 = (3/4)x - (3/4)x +14

which becomes

(7/4)x - 7 = 14

then get rid of -7 by adding on both side

= (7/4)x  = 21

=  x = 12
