Is 3/8 greater than 7/12​
Gennadij [26K]

Answer:no

Step-by-step explanation:put the two numbers in the same denominator

The least common denominator of 8 and 12 is 24. So to get 8 to 24 you multiply it by 3. So 3(3/8) is 9/24.

To get 12 to 24 you multiply it by 2. So 2(7/12) is 14/24. 9/24 is less than 14/24.

Graph the line for y + 1 equals -3/5 parentheses x subtract 4 parentheses​
Stolb23 [73]

Answer:

The graph is shown below.

Step-by-step explanation:

Given:

Equation of a line is y+1=-\frac{3}{5}(x-4)

The equation of a line with a point (x_{1},y_{1}) and slope m is given as:

y-y_{1}=m(x-x_{1})

On comparing the given equation with the standard form, we get

x_{1}=4,y_{1}=-1,m=-\frac{3}{5}

Now, we first plot the point (4,-1).

Slope is -\frac{3}{5}. This means that we have to move 3 units down and 5 units right to get the slope as negative. We mark the second point there.

Now, we plot a line joining both the points. Thus, the graph is drawn.

This composite shape is a rectangle with a semicircle attached on one end. The diameter of the semicircle is 6 feet.What is the
Olin [163]
We know that
area of the composite figure=area of the rectangle+area of semicircle

area of rectangle=b*h
b=10 ft
h=6 ft
area rectangle=10*6----> 60 ft²

area of semicircle=pi*r²/2
r=6/2----> 3 ft
area of semicircle=pi*3²/2-----> 14.13 ft²

area of the composite figure=[60+14.13]-----> 74.13 ft²-----> 74 ft²

the answer is
74 ft²
