Please solve! It's really easy (I think).

Westkost [7]

Answer:

CD = 5.2 cm
A = 27 cm²

Step-by-step explanation:

As per diagram we have:

m∠A = 30°
m∠BCD = 30°

As per 30° right triangle property:

CD = √3×CB/2 = 3√3 ≈ 5.2 cm
and
AC = 2CD = 2×5.2 = 10.4 cm

Area of triangle:

A = 1/2bh
A = 1/2CB*AC
A = 1/2*5.2*10.4 ≈ 27 cm²

A sculpture sits on a pedestal in the shape of a square prism. The side lengths of a base of the prism are 3 feet. The height of

german

Answer:

Total cost of covering the pedestal is $12.54.

Step-by-step explanation:

The pedestal is a square prism so top and bottom are of square shape.

Hence, we have here length = width

We know that the Total Surface Area of a Prism is:

$\text{Total Surface Area = } 2 (l\times w+ w \times h+ h \times l)$

Where l is length,

w is width and

h is height of prism

We know that here w = l = 3 feet

and h = 4 feet

Also, underside of pedestal is not to be covered.

The underside of pedestal is square type.

So,

$\text{Required Total Surface Area = } l\times w+ 2\times w \times h+2\times h \times l$

$\Rightarrow 3 \times 3 + 2 \times 3 \times 4 + 2 \times 3 \times 4\\\Rightarrow 9 + 24 + 24\\\Rightarrow 57\ ft^{2}$

Cost of cover per square foot = $ 0.22

Total cost of $57\ ft^{2}$ $\Rightarrow 0.22 \times 0.57 = \$12.54$

Solve (Y+5)^3/2=4 where y is a real number

koban [17]

Answer:

$y {}^{2} + 10y = - 33.5$

Step-by-step explanation:

(y+5)(y+5)x3/2=4

Y(y+5)+5(y+5) x 3/2=4

$y {}^{2} + 5y + 5y + 25 \times 3 \2 = 4$

$y ^{2} + 10y + 75 \2 = 4$

$y {}^{2} + 10y + 37.5 = 4$

$y {}^{2} + 10y = 4 - 37.5$

$y {}^{2} + 10y = - 33.5$
