Answer:
plant b height will exceed the height of plant a after 16 days.
Step-by-step explanation:
Plant a: 5 cm tall and rate of change = 3 cm per month
Plant b: 4 cm tall and rate of change = 5 cm per month.
Now we have to form the linear equations.
Plant a:
y = 3x + 5, where y is the total height and "x" be the number of months.
Plant b:
y = 5x + 4 , where y is the total height and "x" be the number of months.
Now we have to when the height of the plant a and plant b are the same.
To do that, we have to equivate both the equations and find x.
3x + 5 = 5x + 4
Isolate the variables terms and constants.
5x - 3x = 5 - 4
2x = 1
Dividing both sides by 2, we get
x = 1 ÷ 2
x = 0.5 months.
So after 15 days, the height of the plant a and plant b are the same.
Therefore, plant b height will exceed the height of plant a after 16 days.

4) If 1 inch represents 10 miles on a map, then how many inches will
represent 120 miles?
Answer:
12 inches
Step-by-step explanation:
You can use proportions to solve this:
1/10 = x/120
Cross multiply:
12 = x
Answer:
12 inches.
Step-by-step explanation:
The ratio given is that 1 inch = 10 miles.
The amount given to you is 120 miles. To find the amount of inches, simply divide the total amount of miles (120) with the amount of miles needed to be ratio into inches (10):
120/10 = 12
12 inches is your answer.

Answer:
Step-by-step explanation:
Remark
You are trying to find one of the legs of a right triangle. All you need is the Pythagorean Theorem.
Formula
x^2 + y^2 = c^2
Givens
x = ?
y = 0.9
c = 1.5
Solution
x^2 + 0.9^2 = 1.5^2
x^2 + 0.81 = 2.25 Subtract 0.81 from both sides
x^2 = 2.25 - 0.81
x^2 = 1.44 Take the square root of both sides
sqrt(x^2) = sqrt(1.44)
x = 1.2

The rectangle TV's width is determined by the formula W = 64.3 inches.
What is the diagonal of a rectangle?The formula determines a rectangle's diagonal.
From the Pythagoras Theorem , The hypotenuse² = base² + height² , and
Diagonal of a Rectangle = √ ( Length )² + ( Width )²
Given data ,
Let D represent the diagonal of the rectangular TV.
D is now equal to 90 inches.
Let the TV's rectangle size be 63 inches.
Let W be the TV's rectangular width.
And , Diagonal of a Rectangle = √ ( Length )² + ( Width )²
D² = L² + W²
90² = 63² + W²
Subtracting 63² on both sides of the equation , we get
W² = 90² - 63²
On simplifying the equation , we get
W² = 4131
Taking square roots , we get
W = √4131 inches
W = 64.3 inches
Thus , W is equal to 64.3 inches.
Hence, the rectangular TV is 64.3 inches wide.

Find the measure of the missing angles.
Answer:
c = 110-degrees
b = 70-degrees
Step-by-step explanation:
for c:
linear pair which means it equals 180-degrees
70 + c = 180 *subtract 70 from both sides*
c = 110
for b:

Which expression best represents the value of it? * The local pizza place has placed a new circular sign above the restaurant. The circumference of the sign is 37.68 feet, and the diameter is 12 feet. Which expression best represents the value of pi?
A.37.68/6
B.37.68/12
C.12/37.68
D.6/37.68
Answer:
B
Step-by-step explanation:
The circumference of a circle can be described as the linear distance round the circle
The circumference of a circle = 2πr or πD
π = 3.14
r = radius
d = diameter
the diameter is the straight line that passes through the centre of a circle and touches the two edges of the circle.
π = circumference / 2r or circumference / D

Brian sat in a massage chair at a shopping mall for 8 minutes and paid $9. Norah sat in
the same massage chair for 12 minutes and paid $11. If the relationship between the
number of minutes and the amount paid is linear, with x representing the minutes and y
representing the amount paid in dollars, which of these equations models the situation?
A. x = 0.5y + 5
B. x = y + 1
C. y = 0.5x + 5
D. y = x + 1
Answer:
(1/2)x + $5 (Answer A)
Step-by-step explanation:
Two points on the line representing the cost are (8, $9) and (12, $11).
The change in x is 4 (minutes); this is the 'run.' The change in y is $2 (this is the 'rise'). Thus, the slope of this line is m = rise / run = $2/(4 min), or 1/2 dollar per min.
Applying the slope-intercept formula y = mx + b, we get:
$9 = (1/2)(8) + b, and from this we see that b must be $5.
Then the correct equation is y = (1/2)x + $5.
