Take negative 11 and add positive 8 to it because you are going in the positive direction.
A quadrilateral with 90 degree angles is shown. The lengths of the left and right sides are 10 and 2 y + 4. The lengths of the top and bottom sides are 18 and 10 + 2 x. What is the value of y? 3 4 5 6
The left and right sides would be the same length.
Set the two sides equal and solve for y:
10 = 2y +4
Subtract 4 from both sides:
6 = 2y
Divide both sides by 2:
y = 6/2
y = 3

Answer:
Step-by-step explanation:
(x + 3)² − 5 because :
(x + 3)² − 5 = x² +6x+9 -5 =x²+6x+4
Answer:
B) [tex](x + 3)^2 - 5[/tex]
Step-by-step explanation:
the equation is: [tex]x^2 + 6x + 4[/tex]
we have an equation of the form
[tex]ax^2+bx+c[/tex]
where
[tex]a=1,b=6,c=4[/tex]
and we must complete the square to obtain a perfect square binomial,
we must add and substract the following:
[tex](\frac{b}{2a} )^2[/tex]
which is:
[tex](\frac{6}{2*1} )^2=3^2[/tex]
and then the equation becomes:
[tex]x^2 + 6x + 4+3^2-3^2[/tex]
where the terms [tex]x^2+6x+3^2[/tex] are the components of the perfect square binomial: [tex](x+3)^2[/tex]
and thus, the equation now is:
[tex](x+3)^2+4-3^2\\=(x-3)^2+4-9\\=(x+3)^2-5[/tex]
the answer is: B) [tex](x + 3)^2 - 5[/tex]

Order of Operations: BPEMDAS

Terms/CoefficientsStep-by-step explanation:
Step 1: Define
-8 - 3(w + 13) = 4(w + 11) - 7w
Step 2: Solve for w
Distribute: -8 - 3w - 39 = 4w + 44 - 7wCombine like terms: -3w - 47 = -3w + 44Add 3w on both sides: -47 ≠ 44Here we see that -47 does not equal 44.
∴ w = no solutions.
There is no solution to the equation -8-3(w+13)=4(w+11)-7w, as it simplifies to an untrue statement.
Here is the step-by-step solution:
Distribute the constants through the parentheses:
-8 - 3w - 39 = 4w + 44 - 7w
Combine like terms:
-47 - 3w = -3w + 44
Since -3w on both sides cancels out, we are left with just the constants:
-47 ≠ 44
There is no value for w that will make this equation true, hence there is no solution.

In a fruit punch drink, the 3 ingredients are apple juice, orange juice and cranberry juice. If
1/3
of the drink is apple juice and
1/2
is orange juice then write the ratio of cranberry juice to apple juice to orange juice in its simplest form.
The ratio of cranberry juice to apple juice to orange juice, when the drink consists of 1/3 apple juice and 1/2 orange juice, is 1:2:3.
The student asked for the ratio of cranberry juice to apple juice to orange juice in its simplest form, knowing that 1/3 of the drink is apple juice and 1/2 is orange juice. To find the fraction of the drink that is cranberry juice, we subtract the other two parts from the whole (which is 1):
1 - (1/3 + 1/2) = 1 - (2/6 + 3/6) = 1 - 5/6 = 1/6
So the ratio of cranberry juice to apple juice to orange juice can be written as:
Cranberry : Apple : Orange = 1/6 : 1/3 : 1/2
To compare ratios, we need to have the same denominator. Multiplying each part of the ratio by 6 (the least common multiple of 6, 3, and 2) gives us:
Cranberry : Apple : Orange = 1 : 2 : 3
Therefore, the ratio of cranberry juice to apple juice to orange juice in its simplest form is 1:2:3.

Approximately 3 out of every 25 Americans live in California. About 3 out of every 50 Americans live in Ne
York, and about 2 out of every 25 Americans live in Texas.
a.
Which state has the largest population?
Answer:
California has the largest population out of the three.
Step-by-step explanation:
We would first start by showing the proportions.
California: 3/25
New York: 3/50
Texas: 2/25
You would have to find the least common denominator (in this case, 50) to accurately compare it.
So, if we wanted to convert California's ratio to one with a denominator of 50, we would multiply both sides by 2.
(3*2)/(25*2)
= 6/50.
Now, we can do the same with Texas' population.
(2*2)/(25*2)
= 4/50
Seeing that 3/50 < 4/50 < 6/50, the population of New York would be less than the population of Texas, which is in turn less than the population of California.
Therefore, California has the largest population.
Between which two integers can the square root of 15 be found?
Answer:
3 and 4
Step-by-step explanation:
Consider squares on either side of 15, that is 9 and 16, so
[tex]\sqrt{9}[/tex] < [tex]\sqrt{15}[/tex] < [tex]\sqrt{16}[/tex], that is
3 < [tex]\sqrt{15}[/tex] < 4
Answer:
[tex]3<\sqrt{15}<4[/tex]
Step-by-step explanation:
We are asked to find the integers such that square root of 15 lies between them.
We know that perfect square less than 15 is 9 and perfect square greater than 15 is 16.
We can represent this information in an inequality as:
[tex]\sqrt{9}<\sqrt{15}<\sqrt{16}[/tex]
[tex]\sqrt{3^2}<\sqrt{15}<\sqrt{4^2}[/tex]
[tex]3<\sqrt{15}<4[/tex]
Therefore, the square root of 15 lies 3 and 4.
If a pair of shoes costs $52.50 including a 7.25% tax, what is the original cost of the item before taxes are added?
No other symbols other than the number rounded to the second decimal.
Answer:
The original cost of the pair of shoes before tax is $48.95
Step-by-step explanation:
* Lets explain how to solve the problem
- Assume that the cost of the pair of shoes is 100% before taxes
∵ The cost of the pair of shoes is 100% before taxes
∵ The tax is 7.25%
∴ The price of the pair of shoes after tax = 100% + 7.25% = 107.25%
- This 107.25% equivalent to the price of the pair of shoes including
the tax
∵ The cost of the pair of shoes including tax is $52.50
- Lets use the cross multiplication to find the cost of the pair of
shoes before tax
∵ 100% ⇒ 107.25%
? ⇒ 52.50
- ? represents the cost of the pair of shoes before tax
∴ ? = [tex]\frac{100*52.50}{107.25}=48.95[/tex]
∴ The original cost of the pair of shoes before tax is $48.95
A quadrilateral has vertices at A(-5,5), B(1,8), C(4,2), and D(-2,-2). Use slope to determine if the quadrilateral is a rectangle. Show your work.
Answer:
The quadrilateral is not a rectangle
Step-by-step explanation:
we know that
If a quadrilateral ABCD is a rectangle
then
Opposite sides are congruent and parallel and adjacent sides are perpendicular
Remember that
If two lines are parallel, then their slopes are the same
If two lines are perpendicular, then their slopes are opposite reciprocal (the product of their slopes is equal to -1)
The formula to calculate the slope between two points is equal to
[tex]m=\frac{y2-y1}{x2-x1}[/tex]
we have
A(-5,5), B(1,8), C(4,2), and D(-2,-2)
Plot the figure to better understand the problem
see the attached figure
Find the slope of the four sides and then compare
step 1
Find slope AB
A(-5,5), B(1,8)
substitute in the formula
[tex]m=\frac{8-5}{1+5}[/tex]
[tex]m=\frac{3}{6}[/tex]
[tex]m_A_B=\frac{1}{2}[/tex]
step 2
Find slope BC
B(1,8), C(4,2)
substitute in the formula
[tex]m=\frac{2-8}{4-1}[/tex]
[tex]m=\frac{-6}{3}[/tex]
[tex]m_B_C=-2[/tex]
step 3
Find slope CD
C(4,2), and D(-2,-2)
substitute in the formula
[tex]m=\frac{-2-2}{-2-4}[/tex]
[tex]m=\frac{-4}{-6}[/tex]
[tex]m_C_D=\frac{2}{3}[/tex]
step 4
Find slope AD
A(-5,5), D(-2,-2)
substitute in the formula
[tex]m=\frac{-2-5}{-2+5}[/tex]
[tex]m=\frac{-7}{3}[/tex]
[tex]m_A_D=-\frac{7}{3}[/tex]
step 5
Verify if the opposites are parallel
Remember that
If two lines are parallel, then their slopes are the same
The opposite sides are
AB and CD
BC and AD
we have
[tex]m_A_B=\frac{1}{2}[/tex]
[tex]m_C_D=\frac{2}{3}[/tex]
so
[tex]m_A_B \neq m_C_D[/tex]
It is not necessary to continue verifying, because two of the opposite sides are not parallel
therefore
The quadrilateral is not a rectangle

What is the prime factors of the numbers 48
Answer:
24,12,6
Step-by-step explanation:
48 is even, so you can factor out 2, your first prime factor
Final answer:
The prime factors of 48 are 2 to the power of 4 and 3. You divide 48 by 2 repeatedly until only prime numbers are left, which are 2´ and 3.
Explanation:
Finding Prime Factors
The prime factors of a number are the prime numbers that multiply together to equal the original number. To find the prime factors of 48, you start by finding the smallest prime number that divides 48. In this case, it would be 2. So, you divide 48 by 2 to get 24. You then repeat this process until you are only left with prime numbers.
Here's a step-by-step breakdown:
48 ÷ 2 = 24
24 ÷ 2 = 12
12 ÷ 2 = 6
6 ÷ 2 = 3
Now, you're left with 2, 2, 2, 2, and 3, all of which are prime numbers. So the prime factors of 48 are 2´ (2 raised to the power of 4) and 3.

the length of a dollar bill is 6.14 inches. what is the approximate length of a dollar bill to the nearest centimeter? please help
Answer:
About 16 centimeters
Step-by-step explanation:
In order to convert inches to centimeters, you must multiply the inches by 2.54. Then, round your answer, and you will get 16.
1) 6.14 * 2.54 = 15.5956
2) = 16
The length of a dollar bill is approximately 16 centimeters when converted from inches and rounded to the nearest whole number.
Explanation:To convert the length of a dollar bill from inches to centimeters, we use the conversion factor 1 inch = 2.54 cm. The length of the dollar bill is 6.14 inches. To find the length in centimeters, we multiply 6.14 inches by the conversion factor.
Step 1: Set up the conversion equation:
Length in cm = Length in inches x Conversion factor
Step 2: Substitute the given length and conversion factor:
Length in cm = 6.14 inches x 2.54 cm/inch
Step 3: Carry out the multiplication:
Length in cm = 15.5956 cm
So, the approximate length of a dollar bill to the nearest centimeter is about 16 cm, when rounded to the nearest whole number.
