The perimeter cf a rectangle i: 56 inches" the ratio of the length of the width is 6 : 1. Find the length and the width.
Answer: Length = 24; width =4
Step-by-step explanation
Since the ratio of the length to width is 6:1
Let the length be represented as 6x
And the width be = x
Such that that the Perimeter of the rectangle which is
Perimeter = 2(length + width) becomes
56 = 2(6x + x)
56/2 = 6x+x
28 = 7x
x = 4
Width = 4
Length = 6x= 6 x 4 = 24

The ratio of destroyers to battleships in the navy is 20:15. If the total number of boats is 105, how many battleships are there?
Answer:
45
Step-by-step explanation:
20:15 the ratio can be turned to a fraction
20/15
simplify
4/3
so now add the numerator and the denominator and get 7
then do 105/7=15
and then you do
4x15=60 (Destroyers)
3x15=45 (Battleships)
45 is your answer
A small black cloth bag holds two red counters, two green counters, two
blue counters, and two black counters. All are the same size. Without
looking into the bag, what is the probability of drawing a red counter then
a black counter from the bag without replacement? *
Answer:
1/14
Step-by-step explanation:
P(red, then black) = [tex]\frac{2}{8}[/tex] · [tex]\frac{2}{7}[/tex] = [tex]\frac{4}{56}[/tex] = [tex]\frac{1}{14}[/tex] (simplifed form)

i need help solving this question
Answer:
4 1/6
Step-by-step explanation:
First, you have to convert any mixed numbers to fractions.
Then your initial equation becomes:
25/8÷3/4
Second, you have to apply the fractions formula for division.
= 25 x 4
------------- (You will be dividing.)
8 x 3
=100/24
And if you simplify 100/24, the answer will become:
4 1/6
I hope this helps. :)
Write the equation for the inverse of the function.
y= Arctan (x+Pie/2)
Answer:
y = tan x - pi/2
Step-by-step explanation:
y = arctan(x+pi/2) use that tan y = x is y= arctan x
tan y = x+pi/2; change x with y and find y
tan x= y +pi/2; subtract pi/2 from both sides
-pi/2 + tan x = y
y= tan x -(pi/2) is the inverse function
you can also write it as
y = 1/2(2 tan x -pi)
y = tan x - pi/2

The population of a city can be modeled by the expression p(1.06)^t where t represents the number of years since 1990 and p represents the population in 1990. which statement is correct?
A. the year growth rate of the population is 0.06%
B. the yearly growth rate of the population is 0.6%
C. the yearly growth rate of the population is 1.06%
D. the yearly growth rate of the population is 6%
please respond if you actually know the answer :)
Answer:
D
Step-by-step explanation:
.06 =6%
The expression p(1.06)^t represents D. the yearly growth rate of the population is 6%
What is the population growth rate?The country's yearly average rate of change in population size over a certain time period. It expresses the proportion, growth in population size, and the total population for that year.
Given, The population of a city can be modeled by the expression
[tex]p(1.06)^t[/tex] where t represents the number of years.
This describes the yearly growth rate of the population is 6%.
If in the previous year the population was 100 this year it'll be 106 and next year it'll be 106% of 106 which is 112.36.

Lines a b c and d are shown below. Which lines are parallel? Which line are perpendicular? Explain and jutsify your answer using slopes
Answer:
Lines A and C are parallel
Lines B and D are perpendicular
Step-by-step explanation:
Given
See attachment for lines A to D
Required
Determine the parallel and perpendicular lines
To start with, we calculate the slope of each line.
Line A
The points on line A are:
[tex](x_1,y_1) = (3,-4)[/tex]
[tex](x_2,y_2) = (-1,2)[/tex]
Calculate the slope (m)
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
[tex]m = \frac{2 - (-4)}{-1 - 3}[/tex]
[tex]m = \frac{2 +4}{-4}[/tex]
[tex]m = \frac{6}{-4}[/tex]
[tex]m_1 = -\frac{3}{2}[/tex]
Line B
[tex](x_1,y_1) = (-1,8)[/tex]
[tex](x_2,y_2) = (2,6)[/tex]
Calculate the slope (m)
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
[tex]m = \frac{6 - 8}{2 -(-1)}[/tex]
[tex]m = \frac{-2}{2 +1}[/tex]
[tex]m_2 = -\frac{2}{3}[/tex]
Line C
[tex]y - 9 = -\frac{3}{2}(x + 8)[/tex]
Open bracket
[tex]y - 9 = -\frac{3}{2}x -\frac{3}{2}* 8[/tex]
[tex]y - 9 = -\frac{3}{2}x -3* 4[/tex]
[tex]y - 9 = -\frac{3}{2}x -12[/tex]
Make y the subject
[tex]y = -\frac{3}{2}x -12+9[/tex]
[tex]y = -\frac{3}{2}x -3[/tex]
The slope intercept of an equation is: [tex]y = mx + b[/tex]
Where
[tex]m = slope[/tex]
By comparison:
[tex]m_3 = -\frac{3}{2}[/tex]
Line D
[tex]12x - 8y = 40[/tex]
Subtract 12x from both sides
[tex]12x-12x - 8y = -12x+40[/tex]
[tex]- 8y = -12x+40[/tex]
Divide through by -8
[tex]\frac{- 8y}{-8} = \frac{-12x}{-8}+\frac{40}{-8}[/tex]
[tex]y= \frac{12x}{8}-\frac{40}{8}[/tex]
[tex]y= \frac{3}{2}x-5[/tex]
The slope intercept of an equation is: [tex]y = mx + b[/tex]
Where
[tex]m = slope[/tex]
By comparison:
[tex]m_4 = \frac{3}{2}[/tex]
So, the slopes of the lines are:
[tex]m_1 = -\frac{3}{2}[/tex] [tex]m_2 = -\frac{2}{3}[/tex] [tex]m_3 = -\frac{3}{2}[/tex] [tex]m_4 = \frac{3}{2}[/tex]
Lines with the same slope are parallel.
So:
Lines A and C with slope of [tex]-\frac{3}{2}[/tex] are parallel
Lines with the following relationship are perpendicular:
[tex]m * M = -1[/tex]
Lines B and D are perpendicular because:
[tex]-\frac{2}{3} * \frac{3}{2} = -1[/tex]
[tex]-\frac{6}{6} = -1[/tex]
[tex]-1 = -1[/tex]

which expression below me is equivalent to -3x+5(x+2)?
A.2x+2
B.-x+2
C.2x+10
D.-8x+10
Answer:
C)
Step-by-step explanation:
First use distributive property: a(b +c) =a*b +a*c
-3x + 5(x +2) = -3x + 5*x +5*2
= -3x + 5x + 10 {Combine like terms}
= 2x + 10
(-3x) and 5x are like terms
