The hypotenuse of an isosceles triangles measures 10 inches long. What is the length of one leg of the triangle?

Let one leg be x. Hypotenuse = 10

x² + x² = 10²

2x² = 10²

2x² = 100

x² = 100/2

x² = 50

x =√50

x =√(25 *2)

x =√25 *√2 = 5√2

x = 5√2≈ 5*1.414 = 7.07

Length of each leg≈ 7.07

The leg sides are or at least one is (10 in.)/√(2) = 10√(2)/2 in. = 5√(2) long.

A cafe sells puffs. 5/9 are beef and 1/3 are chicken. The remaining 18 are tuna. Calculate 1. What fraction of the puffs are tuna and 2. How many puffs are there in all. I really need to see the working for this.

Let n be the total number of puffs. Now we can write:

Adding the fractional value of n, we get:

Simplifying and rearranging gives us:

Therefore we can simplify to get:

and finally

The fraction of the puff that are tuna is found from:

5/9 + 1/3 + tuna = 1

tuna = 1 - 5/9 - 1/3. LCM = 9

tuna = 9/9 - 5/9 - 3/9 = (9 - 5 - 3)/9 = 1/9

Fraction of tuna = 1/9

Let all the puffs be x. Recall there are 18 tuna

(1/9)x = 18

x/9 = 18

x = 9*18

x = 162

There are 162 puffs in all.

A newly married couple took out a 5-year \$30,000 loan for their wedding. After 5 years, they paid a total of \$32,800 back to the bank. What was the interest rate on the loan?

Interest = Future value - Principal
I= \$32800 - \$30000 = \$ 2800

Interest at the end of 5 years. Time = 5 years, Principal = \$30000

I = 32800 - 30000 = 2800.

Assuming simple interest.

I = PRT

2800 = 30000*R * 5

30000*R * 5 = 2800

R = 2800 /(30000*5)

R ≈ 0.018667

R ≈ 1.8667 %

Interest ≈ 1.8667% per year.

A rectangle is a closed two-dimensional figure with four sides. The opposite sides of a rectangle are equal and parallel to each other and all the angles of a rectangle are equal to 90°. Observe the rectangle given below to see its shape, sides and angles.

Properties of a Rectangle

A rectangle is a closed figure which has four sides and the angle formed by adjacent sides is 90°. A rectangle can have a wide range of properties. Some of the important properties of a rectangle are given below.

• A rectangle is a quadrilateral.
• The opposite sides of a rectangle are equal and parallel to each other.
• The interior angle of a rectangle at each vertex is 90°.
• The sum of all interior angles is 360°.
• The diagonals bisect each other.
• The length of the diagonals is equal.
• The length of the diagonals can be obtained using the Pythagoras theorem. The length of the diagonal with sides a and b is, diagonal = √( a2 + b2).
• Since the sides of a rectangle are parallel, it is also called a parallelogram.
• All rectangles are parallelograms but all parallelograms are not rectangles.

A parallelogram have opposite side equal and parallel.

Also, if a parallelogram have one of its angle right angle then it can show the property of rectangle.

Hence, the Parallelogram with at least one right angle can be rectangle.

a cashier has a total of 26 bills made up of tens and hundreds the total value is 1610 how many hundreds and tens does she have?

Let the tens be x.

Therefore the hundreds will be (26 - x).

Since they both total to 26.x + (26 - x) = 26

10*x + 100*(26 - x) = 1610

10x + 2600 - 100x = 1610

10x - 100x = 1610 - 2600

-90x = -990

x = -990/-90

x = 11.

So the 10s are x =11, the 100s are (26 -11) = 15

11 tens bills and 15 hundred bills.

A saleswomen sells a dried fruit mixture for \$5.7 per pound and nuts for \$14.55 per pound. She wants to blend the two to get a 10 pound mixture that she will sell for \$9.24 per pound. How much should she use? to get a 10 pound mixture she should use __ lb of fruit mixture and __ lb of nuts.

Let the fruit mixture of \$5.7 per poundbe for x pounds.

The nut of \$14.55 per pound would then be: (10 -x).

Since the total blend of both = 10 pounds,selling for \$9.24 per pound.

cost of 1st type + cost of second type = Total cost of blend mixture

5.7*x + 14.55*(10 - x) = 9.24*10

5.7x + 145.5 - 14.55x = 92.4

5.7x - 14.55x = 92.4 - 145.5

-8.85x = -53.1

x = -53.1/-8.85

x = 6

The other will be (10 -x) = 10 - 6 = 4.

She should use 6 lb of fruit mixture and 4 lb of nuts.

A cylindrical water trough has a diameter of 6 feet and a height of 2 feet. It is being filled at the rate of 4 ft^3/min. How fast is the water level rising when the water is 1 foot deep?

Volume of Cylinder V =πr²h

diameter = 6 feet, radius = 6/2 = 3 feet

dV/dt = (dV/dh) * (dh/dt)by change rule.

V =πr²h

dV/dh = πr² =π*3² = 9π ft²

dV/dt = 2 ft³/min

dV/dt = (dV/dh) * (dh/dt)

2 ft³/min = 9π ft² * (dh/dt)

9π ft² * (dh/dt) =2 ft³/min

(dh/dt) = (2 ft³/min)/(9π ft²)

(dh/dt) = (2/9π) ft/min

So the water level is rising at (2/9π) ft/min.

after 1 second the ball is 76 feet in the air: after 2 seconds it is 144 feet in the air. Find the height of the function. h(x)= ?

General equation for height, h
h = ut + 0.5gt^2

at t=1s, h = 76 feet
76 = u*1 + 0.5*a*1^2
76 = u + 0.5a

at t=2s, h = 144 feet
144 = u*2 + 0.5*a*2^2
144 = 2u + 2a
72 = u + a

(Video) Solving Systems of Equations By Elimination & Substitution With 2 Variables

Subtract 2 equations
0.5a = -4
a = -8
u = 80

So the equation,
h(x) = 80t + 0.5*(-8) t^2
h(x) = 80t - 4t^2
