Answer:

Angle VYZ = 27 degrees

A rhombus has 4 equal sides.

That makes Triangle VWX an isosceles triangle.

That means, Angle WXV is also 63 degrees.

All the angles in a triangle add up to 180 degrees:

63 + 63 + x = 180

126 + x = 180

x = 54 degrees

The angle opposite of Angle VWX (Angle VYX) also equals 54 degrees.

That means Angle VYZ = 1/2 of 54 = 27

Angle VYZ = 27 degrees

Answer:

Step-by-step explanation:

All triangles have a right angle, and triangles have a total degree of 180.

180 = 90 + 63 + a

a = 27

A counter top is 18 feet long and 3 feet wide. What is the area of the counter top in square meters? Use the conversion 1 foot =

podryga [215]

Answer:

Area of the counter top is $5.02\ m^2$ .

Step-by-step explanation:

Given:

Length of the Counter top = 18 feet

Width of the counter top = 3 feet

We need to find the area of the counter top is square meter;

Solution:

Now we need to find the area of the counter top is square meter.

But given data is in feet so we will first convert feet into meters.

1 foot = 0.305 meter.

So 18 feet = Number of meters in 18 feet.

By Using Unitary method we get;

Number of meters in 18 feet = $18\times 0.305 = 5.49\ m$

Length of the Counter top = 5.49 m

Also 3 feet = Number of meters in 3 feet.

Again Using Unitary method we get;

Number of meters in 3 feet = $3\times 0.305 = 0.915\ m$

Width of the counter top = 0.915 m

Now we know that;

Area of the counter top can be calculated by multiplying Length of the counter top with width of the counter top.

framing in equation form we get;

Area of the counter top = $5.49\times 0.915 = 5.0233\ m^2$

Rounding up to 2 decimals we get;

Area of the counter top = $5.02\ m^2$

Hence Area of the counter top is $5.02\ m^2$ .

It is given that y is directly proportional to x. When x = 3, y = 18. (a) Find the equation connecting x and y. (b) Hence, find

guapka [62]

Answer:

see explanation

Step-by-step explanation:

(a)

Given y is directly proportional to x then the equation relating them is

y = kx ← k is the constant of proportion

To find k use the condition when x = 3, y = 18 , then

18 = 3k ( divide both sides by 3 )

6 = k

y = 6x ← equation of proportion

(b)

(i)

when x = 12 , then

y = 6 × 12 = 72

(ii)

when y = 42

42 = 6x ( divide both sides by 6 )

7 = x

Serhud [2]

Answer:

14 3/8 pounds

Step-by-step explanation:

6 pounds plus 8 pounds= 14 pounds. 1/4 + 1/8= 3/8. 1/4 can be turned into 2/8, and 2/8 plus 1/8 equals 3/8. Hope this helps :)

Anyone mind helping?

elena-s [515]

Answer:

15 x^8 y^3

Step-by-step explanation:

The area of a rectangle is given by

A = l*w where l is the length and w is the width

A = ( 5x^6 y^2) *( 3x^2 y)

= 15 x^(6+2) y^(2+1)

= 15 x^8 y^3
