The dimension of the rectangle prism is : 3 1/2 mm , 9 mm and 8 1/2 mm
Express the mixed fraction into decimal :
So, the dimensions are : 3.5mm , 9mm & 8.5mm
Volume of the prism = Length x Breadth x Height
Susbtitute the value and simplify :
Volume of the prism = ( 3.5 x 9 x 8.5 ) mm
Volume of the prism = 267.75 mm
That one of its angles is 90 degrees
Answer:
2 science fiction and 5 mystery
Step-by-step explanation:
First, we will set up a system of equations.
x (science fiction) y (mystery)
x + y = 7 This is the total books bought.
7x + 9y = 59 The amount of each set to the total cost.
Now we solve.
(-7)x + y = 7 equals
-7x - 7y = -49
added to
7x + 9y = 59
this equals
2y = 10
y = 5
Now we know one. We can plug it in to find the other value.
x + 5 = 7
x = 2
7-(-7)=7+7=14. So the answer is 14
The equation of line that has slope 8 and passes though (2,7) is:
Step-by-step explanation:
Given
Slope of line = 8
passes through (2,7)
Equation of line in slope-intercept form is given by:
Putting the value of slope
Too find the value of b, putting (2,7) in the equation
Putting b=-9 int he equation
Hence,
