Answer:
C). The store across town is 8.6 miles away and takes about 24 minutes to get there.
D). Your car averages about 22 miles per gallon in the city Gas is $3.05 per gallon.
Step-by-step explanation:
The information regarding the distance of the store across town from the house, the time required to reach there, the average of the car, and the cost of gas per gallon would assist in calculating if the extra drive is worth buying chicken from the city store.
Cost of chicken in the city store - $2.99 per pound
Average of the car in 1 gallon = 22miles
so, the average of the car in 1 mile = 1/22
Cost of traveling 8.6miles = 8/22 * $3.05
= 24.40/22
Additional cost = $ 1.109
Total cost of buying chicken from the city store = $2.99 + $1.10
= $4.09
Hence, it is not worth to buy the chicken from the store across the town as it is costlier in comparison to $3.79 in nearby store.

You use a pair of shoes to measure a distance. The shoes are 10 3/4 inches long. The distance is equal to the length of 12 of the shoes. What is the distance?
Answer:
10 ft 9 in
Step-by-step explanation:
If you use a pair of shoes to measure a distance and the distance is equal to the length of 12 of the shoes, the distance is 129 inches.
What is an arithmetic operation?It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has basic four operators that are +, -, ×, and ÷.
It is given that, the shoes are 10 3/4 inches long. The distance is equal to the length of 12 shoes.
We can utilize multiplication for a number of common tasks, such as figuring out how much it will cost to buy several identical things, calculating sales tax, and figuring out area and other geometric measurements.
The total distance according to the given condition is,
= 12 × 10 3/4 inches
= 12 × 43/4
= 129 inches
Thus, if you use a pair of shoes to measure a distance and the distance is equal to the length of 12 of the shoes, the distance is 129 inches.

pls tell fast
Answer:
Value of a =3
Value of b =5
Step-by-step explanation:
[tex]If\ the\ polynomial\ p\left(x\right)\ =\ 2x^3\ +\ ax^{2\ }-\ 7x\ +b,\ p\left(1\right)\ =\ 3\ and\ p\left(2\right)\ =\ 19,\ find\ a\ \&\ b[/tex]
We are given p(1)=3 and p(2)=19
Putting x =1 to find p(1)
[tex]p\left(x\right)\ =\ 2x^3\ +\ ax^{2\ }-\ 7x\ +b\\p(1)=2(1)^3+a(1)^2-7(1)+b\\We \ know \ p(1)=3\\3=2+a-7+b\\3=-5+a+b\\a+b=3+5\\a+b=8[/tex]
Now putting x=2 as p(2)=19
[tex]p\left(x\right)\ =\ 2x^3\ +\ ax^{2\ }-\ 7x\ +b\\p(2)=2(2)^3+a(2)^2-7(2)+b\\We \ know \ p(2)=19\\19=2(8)+4a-14+b\\19=16+4a-14+b\\4a+b=19-16+14\\4a+b=17[/tex]
Solving these equations to find values of a and b
[tex]a+b=8---eq(1)\\4a+b=17---eq(2)[/tex]
Subtract both equations
[tex]a+b=8\\4a+b=17\\-\ \ \ - \ \ \ -\\------\\-3a=-9\\a=\frac{-9}{-3}\\a=3[/tex]
So, value of a =3
Now finding value of b bu putting value of a in equation 1
[tex]a+b=8\\3+b=8\\b=8-3\\b=5[/tex]
So, Value of b =5

A laser beam is aimed 25° from horizontal at a mirror 120 m away. The beam bounces off the mirror and continues for an additional 90 m at 20° above horizontal until it hits a target, mirror 2. What is the distance between the origination point and the target?
approximately 85 m
approximately 122 m
approximately 174 m
approximately 194 m
Answer:
Vectors are usually described in terms of their components in a coordinate system. Even in everyday life we naturally invoke the concept of orthogonal projections in a rectangular coordinate system. For example, if you ask someone for directions to a particular location, you will more likely be told to go 40 km east and 30 km north than 50 km in the direction 37° north of east.
In a rectangular (Cartesian) xy-coordinate system in a plane, a point in a plane is described by a pair of coordinates (x, y). In a similar fashion, a vector
→
A
in a plane is described by a pair of its vector coordinates. The x-coordinate of vector
→
A
is called its x-component and the y-coordinate of vector
→
A
is called its y-component. The vector x-component is a vector denoted by
→
A
x. The vector y-component is a vector denoted by
→
A
y. In the Cartesian system, the x and y vector components of a vector are the orthogonal projections of this vector onto the x– and y-axes, respectively. In this way, following the parallelogram rule for vector addition, each vector on a Cartesian plane can be expressed as the vector sum of its vector components:

How many 2 ¼ inch ribbons can you make from a piece of fabric that is 3 feet wide?
Answer:
0.75
Step-by-step explanation:
Ok so we all know that 1/4 is equal to 0.25 as 1/2 is equal to 0.50 and as 3/4 is equal to 0.75. So tell me. after converting the 1/4 to a decimal what do you get? .25 right or just to not confuse you 0.25, so then after converting it to a decimal bring down that whole number which is 2. Put the 2 in the place of that 0 and you get 2.25, after that divide 2.25 by 3. which would equal 0.75. try this and see if im right
What is the solution to -2( 1 - 4x ) = 3x + 8
Answer:
x = 2
Step-by-step explanation:
Given
- 2 (1 - 4x) = 3x + 8 ( distribute parenthesis on left side )
- 2 + 8x = 3x + 8 ( subtract 3x from both sides )
- 2 + 5x = 8 ( add 2 to both sides )
5x = 10 ( divide both sides by 5 )
x = 2

Which division problem would have an estimated quotient of 15 if the divisor and dividend were rounded to the nearest whole number? What is the right option?
Answer:
90.24 divided by 6.3
Step-by-step explanation:
For reaching to the answer, we have to test each of the options given
The first option says that the divisor and dividend is 90.24 and dividend is 6.3
Now if we rounded it
So it would be 90 and 6
So, the quotient is
= 90 ÷ 6
= 15
Hence, the first option is correct
i.e. 90.24 divided by 6.3
And, all the other options are wrong

You rotate triangle ABC, with vertices A(-3, 1), B(-2, 2), and C(-3, 4), 90° counterclockwise about the origin to form triangle A′B′C′. Match each vertex of triangle A′B′C′ to its coordinates.
Answer:
The new vertices will be: A'(-1,-3), B'(-2,-2) and C'(-4,-3)
Step-by-step explanation:
Rotation about the origin depends on the degrees the point is being rotated and direction of rotation.
Let (x,y) be a point on the xy-coordinate plane,
When this point will be rotated about origin 90 degrees counter clockwise, the coordinates of the point become (-y,x) which means that the coordinates will be exchanged and y will be negated.
Given vertices of triangle are:
A(-3, 1), B(-2, 2), and C(-3, 4)
After rotation the new points will be:
A(-3, 1) => A'(-1,-3)
B(-2,2) => B'(-2,-2)
C(-3,4) => C'(-4,-3)
Hence,
The new vertices will be: A'(-1,-3), B'(-2,-2) and C'(-4,-3)

what is the measure of mid-segment DE?
a. 13
b. 6
c. 10
d. 18
Answer:
A.13
Step-by-step explanation:
We can tell that a measurement of the mid segment DE = 13 because of what the length of the line BC equals... The length of BC = 26 this means that the mid segment equals 13 because 26 divided by 2 equals 13... The mid segment we'll be half the half length of the other line given. Hope this helps!
COOKING The instructions on a box of chicken patties state that one patty should be cooked for 2.5 minutes
in the microwave. If more than one patty is cooked, an additional 1.5 minutes should be added per patty.
Write an equation in slope-intercept form to model the cooking time in minutes, y, for x patties.
Answer:
y=1.5x+2.5 ,
y=32x+52 ,
y=32x+2.5 ,
or
y=1.5x+52
The equation in slope-intercept form to model the cooking time in minutes, y, for x patties is y = (3/2)x + 1.
What are lines and their slopes?We know lines have various types of equations, the general type is
Ax + By + c = 0, and the equation of a line in slope-intercept form is
y = mx + b.
Where slope = m and b = y-intercept.
the slope is the rate of change of the y-axis with respect to the x-axis and the y-intercept is the (0,b) where the line intersects the y-axis at x = 0.
Given, On a box of chicken patties state that one patty should be cooked for 2.5 minutes in the microwave.
If more than one patty is cooked, an additional 1.5 minutes should be added per patty.
So, The equation in slope-intercept form to model the cooking time in minutes, y, for x patties.
If we write this as y = 1.5x + 2.5 and put x = 0 , y = 2.5 which is not satisfying the given statement.
∴ y = 1.5x + (2.5 - 1.5). (the additional patty cooking time).
y = 1.5x + 1.
y = (3/2)x + 1.

The drop down options are explicit and recursive.
Answer:
Recursive
Explicit
Step-by-step explanation:
An arithmetic sequence an be represented by a recursive rule which gives the first term and defines the nth term by relating it to the previous term, or by an explicit rule which defines the nth term as a function of n.
The recursive rule is that we have the initial term. To find the subsequent term, we will take that previous term and add it to our common difference.
Hence, we are relating the previous terms to define the nth term.
For the explicit rule, we simply have a function of n. To find the nth term, we can substitute our desired term n for n and evaluate.

Answer:
She can cut 180 (9 - inch) pieces
Step-by-step explanation:
A dressmaker needs to cut 9-inch pieces of ribbon from rolls of ribbon that are 9 feet in length. How many 9-inch pieces can the dressmaker cut from 15 of these rolls of ribbon? Before you try that problem, answer the question below.
Step 1
How many inches of ribbon does the dressmaker have, in total?
1 roll of ribbon = 9 feet
15 rolls of ribbon = x feet
x = 15 roll × 9 feet
x = 135 feet
Converting from Feet to inches
1 foot = 12 inches
135 feet = x inches
Cross Multiply
x = 135 × 12 inches
x = 1620 inches
The dress maker cuts 9 inches each
How many 9-inch pieces can the dressmaker cut from 15 of these rolls of ribbon?
15 rolls of ribbon = 1620 inches of ribbons
Hence: = 1620 inches/9
= 180 pieces
She can cut 180 (9 - inch) pieces
