What is the volume of the shaded solid? Round to the nearest tenth of a cubic unit. 11.6 units3 45.4 units3 57.0 units3 68.6 units3
Answer:
45.44units^3
Step-by-step explanation:
Volume of the shaded part = Volume of the triangular based prism - Volume of square based prism
Volume of prism = Base area * Height
Volume of the triangular based prism = (5 * 4 * 5.7)/2
Volume of the triangular based prism = 57units^3
Volume of square based prism = 1.7* 1.7 * 4
Volume of square based prism = 11.56units^3
Taking the difference
Volume of the shaded solid = 57 - 11.56
Volume of the shaded solid = 45.44units^3

Solve: 7x-12<7(X-1)
All Real Numbers
x>7
x<5
Answer:
There will be no real solution. A further explanation is given below.
Step-by-step explanation:
The given equation is:
⇒ [tex]7x-12<7(x-1)[/tex]
On solving bracket, we get
⇒ [tex]7x-12<7x-7[/tex]
On putting numbers on the right side and x's on the left side of the equation, we get
⇒ [tex]7x-7x<-7+12[/tex]
⇒ [tex]0<5[/tex]
Thus the above is the appropriate solution.
Convert the circle to standard form.
[tex] {9x}^{2} + {9y}^{2} + 18x + 9y - 36 = 0[/tex]
Answer:
(x + 1)² + (y + 1)² = (√6)²
Step-by-step explanation:
Group the x- and y- terms together:
9x^2 + 18x + 9y^2 + 9y = 36
Factor out the coefficient 9:
x^2 + 2x + y^2 + y = 4
Complete the square of x^2 + 2x and then do the same for y^2 + 2y:
x^2 + 2x + 1 - 1 + y^2 + 2y + 1 - 1 = 4
Rewrite x^2 + 2x + 1 as the square of the binomial x + 1:
(x + 1)^2 + (y + 1)^2 - 2 = 4
Collect the constant terms on the right side:
(x + 1)^2 + (y + 1)^2 = 6
Rewrite 6 as (√6)^2:
(x + 1)² + (y + 1)² = (√6)² is the equation in standard form (x - h)² + (y - k)² = r²
Completing the square is done as follows: x^2 + 2x
Start with x^2 + 2x
1. Take half of the coefficient of x, which results in 2/2, or 1
2. Square this result and add it to, and subtract it from x^2 + 2x
x^2 + 2x + 1 - 1
3. Rewrite the first three terms as the square of a binomial:
x^2 + 2x + 1 - 1 = (x + 1)² - 1.
Do the same for y² + 2y.

Answer:
x=85, y=45
Step-by-step explanation:
Answer:
x = 85 degrees
y = 45 degrees
Step-by-step explanation:
x = 180 - 95 (Angles on a straight line add up to 180 degrees.)
x = 85 degrees
y = 180 - 50 - 85 (Interior angles of a triangle add up to 180 degrees.)
y = 45 degrees

Find the value of y
Substitute the x in -3x - 8y = 4 with -y-3
We get
-3·(-y-3) - 8y = 4
3y + 9 - 8y = 4
-5y = 4-9

2k + (−3m ) − 6k + 2m
A. −4k + (−2m)
B. −4k + (−m)
C. 4k − 5m
D. 4k − m
Answer:
−4k + (−m)
Step-by-step explanation:
combined like term:
solve for k: 2k - 6k = -4k
solve for m: -3m + 2m = -1m which is -m
combined together the equation: -4k + -m or it can just be -4k - m

Simplifying Rational Expressions
The quotient of two polynomial expressions is called a rational expression. We can apply the properties of fractions to rational expressions, such as simplifying the expressions by canceling common factors from the numerator and the denominator. To do this, we first need to factor both the numerator and denominator. Let’s start with the rational expression shown.
