in the question ,
it is given that ,
On the map [tex]1\frac{1}{2}[/tex] miles is equal to [tex]1\frac{7}{8}[/tex] inches .
we first convert the mixed fraction to normal fractions ,
we get
[tex]1\frac{1}{2}[/tex] miles = (1*2+1)/2 = 3/2 miles
and
[tex]1\frac{7}{8}[/tex] inches = (8+7)/8 = 15/8 inches
So, the statement becomes
On the map 3/2 miles is equal to 15/8 inches .
So 1 mile = (15/8)/(3/2) = (15*2)/(8*3) = 30/24 = 5/4
so , the unite rate is 5/4 inches per mile .
given the road B is 15 miles long .
and the unit rate is 5/4 .
so 15 miles = 15 *(5/4) = 75/4 = 18.75 inches
Therefore , The unit rate per inch on the map is 5/4 , and the length of road B is 18.75 miles.
The given question is incomplete , the complete question is

Larry plants to invest 275,000 for 30 years at an anticipated rate of 6% per annum compounded yearly what is the approximate difference in his ending balance of the actual rate is 5% instead of six
Answer:
$390,000
Explanation
To do this, we will use the compound interest formula;
A = P(1+r)^t
P = 275000
rate r = 6%
Time t = 30years
Substitute
A = 275000(1+0.06)^30
A = 275000(1.06)^30
A = 275000(5.7435)
A = 1,579,460.07
For the rate of 5%
A = 275000(1+0.05)^30
A = 275000(1.05)^30
A = 275000(4.3219)
A = 1,188,534.15
Takeing their difference;
Difference = 1,579,460.07-1,188,534.15
Difference =390,925.92
Hence the approximate difference in his ending balance of the actual rate is 5% instead of six is about $390,000

13 What value of x makes the equation modeled below true? PHONE 1 1 1 A x = 1 B x = -1 C x = 7 D x = -5 I
SOLUTION
Step 1 : We need to recognize the value of x in 5 places means 5 x
and the value of 1 in 6 times means 6,
so we have that: 5 x + 6 = 1 .
Step 2 : We need the linear equation: 5 x + 6 = 1
collecting like terms, we have that:
5 x = 1 - 6
5 x = - 5
Divide both sides by 5 , we have that:
x = - 1
CONCLUSION : The value of x = -1 ( OPTION B )
arif's backyard is 22 by 32 meters. he wants to put a flower garden in the middle of the backyard, leaving a strip of grass of uniform width around the flower garden. to be happy, arif must have 288 m^2 of grass. under these conditions what will the length and width of the garden be?
The dimension of the flower garden, which located in the middle of the backyard surrounded by a strip of grass, is 26 m length and 16 m width.
The situation can be depicted on the attached picture.
We need to translate the word problem into algebraic expressions.
Let x be the width of the grass strip.
Let A be the area of the grass strip.
Then,
A = 2 . 22x + 2 . (32 - 2x)x
288 = 2 . 22x + 2 . (32 - 2x)x (divide by 2)
144 = 22x + x(32 - 2x) (divide by 2)
72 = 11x + x(16 - x)
72 = 27x - x²
x² - 27x + 72 = 0
This is a quadratic equation. One of the methods to solve a quadratic equation is by factorization.
Factorize the left side:
(x - 3) (x - 24) = 0
x = 3 or x = 24
The length of the flower garden = 32 - 2x
The width of the flower garden = 22 - 2x
Substitute x = 3:
The length of the flower garden = 32 - 2 . 3 = 32 - 6 = 26 m
The width of the flower garden = 22 - 2 . 3 = 16 m
Note that if we substitute x = 24, it will results in negative values while the dimension is always positive.

The length of the rectangle is 5 more than twice the width. If the perimeter is 10 times that of the width, what is the width, length, and perimeter of the rectangle?
The length of the rectangle is 10, the width is 2.5 and the perimeter is 25
Let the width of the rectangle be x
The length of rectangle = 2x + 5
The overall length of the outline determines a rectangle's perimeter in two dimensions. We add the lengths of all four corners of a rectangle to find its perimeter. Since the opposite sides of a rectangle are always equal, we must determine the length and width of the rectangle in order to determine its perimeter.
Perimeter = 10 times of width
= 10*x
= 10x
The formula for the perimeter of a rectangle is given:
Perimeter = 2(Length+Breadth)
10x = 2(x + 2x+5)
10x = 2(3x+5)
10x = 6x + 10
4x = 10

What are the coordinates of the point on the directed line segment from (3,−3) to (7,5) that partitions the segment into a ratio of 5 to 3
The coordinates along the directed line segment is (37/7, 11/7)
How to find the coordinates of the point?The points are given as:
A = (3, -3)
B = (7, 5)
The ratio on the segment can be represented as;
m : n = 4 : 3
So, we have the coordinates of the point that lies along the directed line segment to be
Point = 1/(m + n) * (mx2 + nx1, my2 + ny1)
So, we have:
Point = 1/(4 + 3) * (4 * 7 + 3 * 3, 4 * 5 + 3 * -3)
Evaluate
Point = 1/7 * (37, 11)
Evaluate the products
Point = (37/7, 11/7)
Hence, the coordinates of the point is (37/7, 11/7)

The finish line is 253 m away. You begin to run from rest. You must reach a velocity of 53.2 m/s or you will explode. What must your acceleration be?
The acceleration require for the body to not explode will be 0.2941[tex] m/s^2 [/tex]
The finish line as given is 253m away so that distance to be covered will be 253m.
Also we had started to run from rest so that initial velocity will be 0m/s.
We should take care that we could not explode and this is possible only if we reach to the velocity of 53.2m/s. So our final velocity will be 53.2m/s.
Now average velocity will be the sum of initial velocity and final velocity divided by 2.
∴ Average velocity = (initial velocity + final velocity) / 2.
∴ Average velocity = (0 + 53.2) / 2 = 53.2 / 2 = 26.6m/s
As we know that average velocity will give us an average time of the run by formula average speed = distance / average time.
∴ Average time = distance / average speed
∴ Average time = 253 / 26.6 = 9.51s.
Now as we know by the formula to calculate acceleration we need the average velocity, average time and we have both of them.
∴ Acceleration = [tex] \frac{average\ velocity}{(average\ time)^2}[/tex]
∴ Acceleration = [tex] \frac{26.6}{(9.51)^2}[/tex]
∴ Acceleration = [tex] \frac{26.6}{90.44}[/tex]

Answer: y = (5x/4) + 2
Step-by-step explanation:
Answer:
y = 5/4x + 2
Step-by-step explanation:
First, we convert 4x + 5y = 15 to slope intercept form (y=mx+b):
5y = -4x + 15
Divide both sides by five
y = -4/5 (x) + 3
The slope is -4/5
A perpendicular slope is the negative reciprocal of the other line. To find the negative reciprocal, you switch the numerator and denominator and switch the sign.
Slope = 5/4
Plug the slope and (-4, -3) into the slope-intercept form:
-3 = ( 5/4 · -4 ) + b
Isolate b (the y-intercept):
-3 = -5 + b
b = 2
y = 5/4x + 2

Vinny is serving punch to guests at a party. He has $\frac{3}{4}$ of a gallon of punch, and he pours $\frac{5}{64}$ of a gallon into each guest's cup, filling each to the top. At the most, how many guests' cups can he fill to the top?
In serving punch to guests at the party, Vinny can fill 9 guests' cups to the top based on this unit rate.
What is a unit rate?The unit rate is the ratio of a variable to another.
The whole number here is the total gallons of punch available to serve the guests.
The unit rate is the volume that each guest's cup can hold or contain.
This implies that the ratio is 5/64: 3/4
The total number of gallons of punch = 3/4 or 0.75 gallons.
The volume or capacity of each guest's cup = 5/64 gallons or 0.078125.
The number of guests' cups to fill to the brim = 9.6 cups (0.75/0.078125)
= 9 guests' cups.
Thus, Vinny can fill 9 guests' cups to the brim, using the given ratio or unit rate.
