Solve using a proportion.
Advocard [28]

Answer:

t = 24 yards

Step-by-step explanation:

Since the trapezoids are similar then the ratios of corresponding sides are equal, that is

\frac{t}{c} = \frac{u}{d}

Substitute in given values

\frac{t}{0.4} = \frac{15}{0.25} ( cross- multiply )

0.25t = 6 ( divide both sides by 0.25 )

t = 24

AysviL [449]

Solution:

As we have to write an expression , which evaluates to true if the value of the integer variable x is divisible (with no remainder) by the integer variable y, y≠0.

so, when x is divided by y we should get remainder as 0.

Using Euclid division lemma

x= y* q + m, i.e when an integer x is divided by y gives quotient q and remainder m.

Here , m=0

So, x = q * y

So, the expression which describes the above relationship is ,

\frac{x}{y}=q, where q is Quotient.

A silo is constructed using a cylinder with a hemisphere on top. The circumference of the hemisphere and the circumference of th
givi [52]
1. The surface that will be exposed to the rain is the lateral surface of the cylinder and the hemisphere.

2. The lateral area of the cylinder is a rectangle with height equal to the height of the cylinder and width equal to the circumference of the base of the cylinder.

3. the circumference of the base = 2\pir=2*\pi*5=10\pi
so the lateral area = 10\pi*h=10\pi*40=400\pi (ft^{2})

4. The surface area of a sphere is 4 \pi  r^{2}
so the surface of the hemisphere = \frac{1}{2} *4 \pi r^{2}=2 \pi (5)^{2}=50 \pi(ft^{2})

5. Total area exposed = 450\pi ft^{2}
