Mike's area basement is 2 times larger than Jack basement area.
Area of a rectanglearea = lw
where
l = length
w = width
Therefore,
Jack's basement area:
length = 6 ft
width = 5 ft
area = 6 × 5 = 30 ft²Mike's basement area;
length = 12 feet
width = 5 feet
area = 12 × 5 = 60 ft²Therefore, Mike's area basement is 2 times larger than Jack basement area.
Mike's basement area = 2(Jack basement area)
60 = 2(30)

By what percent will a fraction increase if its numerator is decreased by 30%
а
and its denominator is decreased by 50%?
Answer:
40%
Step-by-step explanation:
Let x = numerator
Let y = denominator
[tex]\implies \dfrac{x}{y}[/tex]
Decreased by 30% = 100% - 30% = 70% = 70/100 = 0.7
Decreased by 50% = 100% - 50% = 50% = 50/100 = 0.5
[tex]\implies \dfrac{0.7x}{0.5y}[/tex]
[tex]\implies \dfrac{0.7}{0.5}=1.4[/tex]
[tex]\implies 1.4 \ \dfrac{x}{y}[/tex]
1.4 as a percentage = 1.4 x 100 = 140%
Therefore, the percentage increase is 140 - 100 = 40%

Answer:
(a) (-∞, -8) (-6, -4) (-2, ∞)
(b) -6, -2
(c) negative
(d) 5
Step-by-step explanation:
(a) A function is "decreasing" when the y-value decreases as the x-value increases.
⇒ the function is decreasing over these intervals : (-∞, -8) (-6, -4) (-2, ∞)
(b) Local maxima are the points on the function where it reaches a maximum.
⇒ maxima at x = -6 and x = -2
(c) negative
(d) 5

Y= -2x – 3
4y + x =16
Answer:
(-4,5)
*View attached graph*
Step-by-step explanation:
y = -2x - 3
4y + x = 16
4y + x = 16
4(-2x - 3) + x = 16
-8x - 12 + x = 16
-7x - 12 = 16
+12 + 12
-7x = 28
/-7 /-7
x = -4
4y + x = 16
4y + (-4) = 16
4y - 4 = 16

find the area 8ft. 7ft. 14ft. ( EXPLAIN)
Answer:
The area is 77 ft.
Step-by-step explanation:
The formula for area of a trapezoid is 1/2 (base1 + base2) x height.
So, 1/2 (14+8) x 7 = 77.
Answer:
77Ft
if we were to ignore the extra "space" or area, and just do the area of the square we would get 8x7, but you probably want to know how I figured the area of both triangles, well this is simple the triangle has a height of 7 while it has a base(bottom) of 3 since 14-8(top)=6 and there are two triangles and they are the same lenght, when there is a triangle we do the base x height then divide by 2 since it's half a square so we do in this situation 3x7=21 and since there is another triangle we do it one more 3x7=21 add them together 3x7x2=42 then divide this by 2 and we get 21, we then add this to 56 which is the area of the square and get our result 77ft

Fill in the blank so that the ordered pair is a solution of y=9x - 9.
( ), 63
Answer:
(8, 63)
Step-by-step explanation:
The ordered pair is a solution to the equation when substituting the values for x and y make the equation a true statement.
If we let x represent the first number of the ordered pair, it will be a solution when ...
63 = 9x -9
7 = x -1 . . . . . . . divide by 9
8 = x . . . . . . . add 1
The blank gets filled with 8, so the ordered pair is (8, 63).

Sine : Opposite/Hypotenuse
Cosine : Adjacent/Hypotenuse
Tangent : Opposite/Adjacent
In this figure, we are given the measure of a 23° angle, and two sides that are opposite of the angle, and the hypotenuse.
This means we need to use sine:
[tex]sin(23)=\frac{x}{18}[/tex]
Multiply both sides by 18:

the angles of a triangle are(x+10), (x+40) and (2x-30). Find the measure of all angles and name the type of triangle
Answer:
x=40
Step-by-step explanation:
(x+10)+(x+40)+(2x-30)=180
(x+x+2x)+(10+40-30)=180
4x+20=180 step 1: -20 on both sides
4x=160 step 2: /4 on both sides
