Rectangle A is similar to rectangle B by scale factor r. The length of rectangle A is 1. 5r+2. 25 units. The length of rectangle B is 3 unite. What is the scale factor

Answers

Answer 1

The scale factor of the two rectangles is 1.5

Describe the rectangle.

According to Euclidean Plane Geometry, a rectangle is a quadrilateral with equal opposed sides and four right angles. In other words, a rectangle is a parallelogram with a right angle of 90 degrees or an equiangular quadrilateral (i.e., 360°/4 = 90°). A rectangle is referred to as a square if its four sides are all the same length.

The ratio of the matching side lengths of two comparable figures is known as the scale factor. We know that the ratio of the respective side lengths of the two rectangles equals equivalent to r since Rectangle A and Rectangle B are similar to one another by the scale factor r.

We can set up the following ratio to determine the scale factor if the lengths of rectangles A and B are 1.5r+2.25 units and 3 units, respectively.

(1.5r+2.25) / 3 = r

Solving for r, we get:

r = (1.5r + 2.25) / 3

multiply both sides of the equation by 3

3r = 1.5r + 2.25

Subtract 1.5r from both sides

1.5r = 2.25

divide both sides by 1.5

r = 2.25/1.5

r = 1.5

Therefore, the scale factor of the two rectangles is 1.5.

Step-by-step explanation:

The Jackson family is planning a weekend vacation. They plan to rent a car from the ABC Car Rental Company. Let m represent the number of miles the family will drive. Let c represent the cost for renting a car. Write an equation that shows what the cost for renting a car will be.


Weekend Special: $40 + $0. 10 per mile

Answers

An equation that shows what the cost of renting a car will be: C=R+mc.

Let the rental cost = R

consider m to be the number of miles driven= m

let c be the cost per mile

And C is the total cost of renting;

Then C = R+mc

the given equation $40 + $0. 10 per mile

Now, in the above equation consider:

R =$40 ( the rental cost)

c = $0.10 ( the cost per mile)

The total cost is C = $40+$0.10m

Ex:

if m is known assume m=1000 miles

Then the total cost C = $40+($0.10/mile)(1000miles)

then  C = $40+$100=$140

Find the values of x and y in parallelogram PQRS.

PT=​y, TR=4x+​1, QT=2​y, TS=5x+8

Answers

The values of x and y in parallelogram PQRS are x =2 and y = 9

How to determine the values of x and y in parallelogram PQRS

From the question, we have the following parameters that can be used in our computation:

The parallelogram

On the parallelogram, we have the following readings

PT=​y, TR=4x+​1, QT=2​y, TS=5x+8

Rewrite them as

PT= ​ y

TR = 4x + ​1

QT = 2​y

TS = 5x + 8

Because the point T is the midpoint of the parallelogram, we have

PT = TR

QT = TS

Substitute the known values in the above equation, so, we have the following representation

y = 4x + 1

2y = 5x + 8

This means that

8x + 2 = 5x + 8

Evaluate the like terms

3x = 6

So, we have

x = 2

Substitute x = 2 in y = 4x + 1

y = 4 x 2 + 1

So, we have

y = 9

Hence, the values are 2 and 9

Can you solve Pythagorean theorem with only C?

Answers

The Pythagorean theorem can be solved using a C programme, therefore yes. The Pythagorean theorem states that the hypotenuse's square length of a right triangle equals the sum of the squares of its other two sides. The slope is the side that faces the right angle.

Therefore, given the lengths of the two shorter sides (a and b), the length of the hypotenuse can be calculated using the formula: c = sqrt(a^2 + b^2).

Here is an example C program that calculates the length of the hypotenuse of a right triangle given the lengths of the other two sides:

#include <stdio.h>

#include <math.h>

Above command is for library

int main() {

 double a, b, c;

Above command to initiate the variable.

  printf("enter the first side's length.: ");

 scanf("%lf", &a);

To enter the value in program

 printf("enter the second side's length.: ");

 scanf("%lf", &b);

Enter the value and print the value

  c = sqrt(a*a + b*b);

Arithmetic command

   print("The hypotenuse's length is: %lf\n", c); return 0;}

Print the value and return the program value to zero.

This program prompts the user to enter the lengths of the two shorter sides of the triangle, calculates the hypotenuse length using the Pythagorean theorem, and then prints the result.

Step-by-step explanation:

To arrive at this answer, we can first convert 3⅛ and 1⅔ to fraction form.

3⅛ can be written as 3 + 1/8, which is equal to 3 + 1/8 = 25/8.

Similarly, 1⅔ can be written as 1 + 2/3, which is equal to 1 + 2/3 = 5/3.

Therefore, 3⅛ ÷ 1⅔ is equal to (25/8) ÷ (5/3) = (25/8) * (3/5) = (325)/(85) = 75/40 = 1 + 35/40 = 1 + 35/40 = 1.875.

How do you solve basic equations in algebra 1

Answers

Really depends on what you mean by “basic” and “algebraic”. If I take “algebraic” to mean polynomial, and “basic” to mean having one variable and a solution that you can find with standard techniques, then it’s “simple” — for a suitably generous definition of the word.

First, get all your stuff on one side so that you have P(x)=0
P
(
x
)
=
0
for some polynomial P
P
. This is done by subtracting both sides by everything on the right hand side, and combining terms that have the same power of x
x
. For convenience, order your terms so that the biggest powers of x
x
come first, and they get smaller as you go, so that the last term is one without an x
x
, if you have one. If this isn’t a polynomial, then this equations isn’t algebraic, so stop following this guide.

Possible mid-step, if you don’t have a term without an x
x
, then x=0
x
=
0
is a solution, and you can divide by the smallest power of x
x
so that now you should have a term without an x
x
. If there’s no smallest power of x
x
, you started with 0=0
0
=
0
which is always true. If the term without an x
x
is the only one, your equation looks like a=0
a
=
0
for some nonzero a
a
, so you’re out of solutions and can stop here.

Next, figure out the degree of P
P
. This is super easy if you did everything correct up until now, because it will be the power of x
x
on the very first term, which should be the biggest power of x
x
you have, and should be at least 1
1
.

Another possible mid-step, if your degree is more than 4
4
, check if the least common multiple of all the powers of x
x
is greater than 1
1
, and check that the degree divided by the least common multiple is 4
4
or less. If this is the case, make the substitution z=xm
z
=
x
m
where m
m
is the least common multiple. Then continue on to solve the equation for z
z
, and then turn those into solutions for x
x
with x=z√m
x
=
z
m
. If you don’t have a degree 4
4
equation, then you might be out of luck. At this point, I think we can no longer call the equation “basic”, as it might not even have a closed-form solution.

Lastly, at this step you should have a polynomial of degree between 1
1
and 4
4
, in which case you will use the corresponding formula: linear, quadratic, cubic, or quartic. The term “linear formula” isn’t really in wide use, but it simply states that the equation
. The other three can be found easily via the internet. The quadratic formula is fairly manageable, the cubic formula is a bit unwieldy but not too bad, and the quartic formula is a bit of a nightmare but if you’re at this point it’s probably the only way.

So there you go, a more or less complete tutorial on how to solve any “basic” “algebraic” equation (for the definitions given above). There are a couple of heuristic techniques you can also try before giving up, such as factoring by grouping, the rational root theorem, and Descartes rule of signs, but none of these techniques are guaranteed to be of any help. Most polynomials of degree 5 or greater don’t have closed-form solutions, so don’t be discouraged if you can’t find them. At that point, if you really need those solutions, you can try numerical methods, but I’ll leave that out of this answer.

For example, if Ramiro's sample shows that 40 out of the 60 people he surveyed use the library to study, we can estimate that approximately 40/60 = 67% of the school's students use the library to study. We can then use this proportion to estimate that approximately 540 x 67% = 361 students at the school use the library to study.

Answers

If Imani was assigned to make 64 cookies for the bake sale. If Imani made 25% more than they were assigned. The number of cookies that were left after the bake sale is: 8.

How to find the cookies left?

Number of cookies  sold:

Number of cookies  sold = 0.90 × [(1+.25)×64]

Number of cookies  sold = 0.90 × [(1.25)×64]

Number of cookies  sold = 0.90 × 80

Number of cookies  sold = 72

Number of cookies left:

Number of cookies left = 80 - 72

Numbers of cookies left  = 8

Therefore the number of cookies left is 8 cookies.

at a local cafeteria there are 10 vegetable selections available how many three vegetable plates maybe made

Answers

The number of vegetable plates can be made = 120

We know that a combination is nothing but a way of selecting items from a collection. In combination the order of selection does not matter.

We know that a formula for a combination is,

^nC_r = n! / r!(n - r)!

where,  ^nC_r = number of combinations

n = total number of items in the collection

r = number of choosing items from the collection

and n! = n × (n - 1) × (n - 2) × . . . × 1

Here, we have n = 10 and r = 3

Using combination formula,  the total number of plates made:

^10_C_3

= 10! / (3! × (10 - 3)!)

= 10! / (3! × 7!)

= (10 × 9 × 8 × 7!) /( 3! ×7!)

= (10 × 9 × 8) / (3 × 2 × 1)

= (90 × 8) / 6

= 720/6

= 120

Therefore, 120 vegetable plates maybe made
