In the blueprint for A rectangular balcony is 1 inch by 1.75 inches if the actual length is 7 feet what is the perimeter

Answers

Answer:

22 feet

Step-by-step explanation:

Given

  • In blue print,dimensions of rectangular balcony are, length(l)=1.75inch and breadth(b)=1inch
  • The actual length(L)=7 feet

To find the actual perimeter, we need the breadth of balcony(B)

The ratio of length to breadth in blue print must be equal to the ratio of actual length to breadth

\frac{\text{length of rectangular balcony in blueprint}}{\text{breadth of rectangular balcony in blueprint}} =\frac{\text{length of rectangular balcony actually}}{\text{breadth of rectangular balcony actually}}

(l)/(b) =(L)/(B) \nB* l=L * b\nB= (L * b)/(l)=(7 * 1)/(1.75) =4

Therefore Breadth actually=4 feet

⇒Perimeter

=2*(length+breadth)\n=2*(7+4)\n=2*(11)\n=22

Therefore perimeter of rectangular balcony= 22 feet

A line with a slope of 1 passes through the point (3,-8). What is it's equation in slope-intercept form?​

Answers

Answer:

Given:

Slope(m)= 1

Passing Point = (3,-8)

Using one point formula,

y-y1 = m(x-x1)

or, y+8 = 1×(x-3)

or, y+8 = x - 3

or, x - y = 11

Now,

Dividing both sides by 11, we get

x/11 - y/11 = 1 --------i)

Comparing eqn. i) with slope intercept form [x/a + y/b = 1]

Answer: The equation would be y=1x-11

Step-by-step explanation:

slope of this line is 1

y=1x

3 times 1 = 3

to get from 3 to -8 we subtract 11

y=1x-11

What is the volume of a cube with 1/3 inch sides

Answers

cube is a shape with all sides equal

where length - 1/3 inches

width - 1/3 inches

height - 1/3 inches

the formula to find volume is as follows

volume = (1)/(3) *(1)/(3) * (1)/(3)

numerators should be multiplied by numerators and denominators by denominators

volume = (1*1*1)/(3*3*3) = (1)/(27)

volume of the cube is 1/27 in.³

The formula for cube volume is s^3=volume
1/3*1/3*1/3=1/27

When 2 fractions refer to the same whole explain why the fraction with a lesser denominator has larger pieces than the fraction with a greater denominator

Answers

The denominator tells how many pieces the whole is broken into. So a denominator of two tells you that the whole is broken into two pieces. A denominator with 8 tells you that the whole is broken into eight pieces. Think of a pie. if it is cut into two pieces that's two halves. if it is cut into 8 pieces then that is eighths.
