Answer: The slope is 2/3

Step-by-step explanation:

The difference in the rise (y-values) 2, divided by the difference in the run (x-values) 3, is 2/3.

You can see this by looking at the places where the graphed line crosses the grid, and counting the squares in each direction between those points, or you can use the formula (y - y₁) ÷ (x - x₁)

Using the values of coordinates (3,1) and (0, -1)

1 -(-1) ÷ 3 - 0

2 ÷ 3

2/3

One of two complementary angles is 4 degrees more than the other. Find the angles. (Recall that complementary angles are angles

emmasim [6.3K]

$\displaystyle \\ 
\alpha + \beta = 90^o \\ 
\alpha - \beta = 4^o \\ 
\texttt{----------- } + \\ 
2\alpha ~~/~= 94^o \\ \\ 
\alpha = \frac{94}{2} = \boxed{47^o}\\ \\ 
 \beta = 90 -\alpha = 90 - 47 = \boxed{43^o}

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

Elenna [48]

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

⇒

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

$\frac{l}{b} =\frac{L}{B} \\B\times l=L \times b\\B= \frac{L \times b}{l}=\frac{7 \times 1}{1.75} =4$

Therefore Breadth actually=4 feet

⇒Perimeter

$=2\times(length+breadth)\\=2\times(7+4)\\=2\times(11)\\=22$

Therefore perimeter of rectangular balcony= 22 feet
