Thus 16:8 and 2:1 are equivalent.
→ 16:8
divide both by 8
[tex]\rightarrow \sf \dfrac{16}{8} :\dfrac{8 }{8}[/tex]
simplify
→ 2 : 1
Answer:
Yes! Because they are in proportion: 1x8 = 8, 2x8 = 16 therefore, 2:1 and 16:8 are equivalent. Similar to equivalent fractions - you need to multiply both numbers by the same number.

If a translation is described as (x -5, y), how has the original image changed?
Answer:
It moves the x value 5 units to the left.
Step-by-step explanation:
"x - 5" means that we are subtracting 5 to whatever x value we are given. The "y" value doesn't change.
Since we are subtracting to the x value, we are going to move left 5 units.
Let's say we had the point (5, 5).
If we use the translation rule;
(5 - 5, 5)
(0, 5)
We moved the x value 5 units to the left.

find angle b show your work
Answer:
42°
Step-by-step explanation:
The angle measure of 295° just means we are working with a circle.
A circle totals to 360°.
If we add what we are given; 295 + 23 = 318°
We have the total angle measure we are given and "b" which we need to solve.
We can subtract 360 by what we are given to find angle "b"
360 - 318 = 42°

Rakim charges $2 per hour for tutoring plus a $7 fee.
Joan charges a $3 fee plus $4 per hour.
When will their tutoring fees be the same (aka equal)
How many hours of tutoring will occur before the fees are the same?
How much has each person been paid in tutoring fees?
Answer:
after 2 hours, they will have the same fee.
they will have been payed 11$
Step-by-step explanation:
if you say h = hours of tutoring,
Rakim charges 7 + 2h
Joan charges 3 + 4h
since you want them to be the same, you can write the following equation:
7 + 2h = 3 + 4h
subtract 2h from each side
7 = 3 + 2h
subtract 3 from each side
4 = 2h
divide both sides by 2.
h = 2
after 2 hours, they will have the same fee.
they will have been payed 11$
"they will have been payed" ah yes the grammar.

Write the number in expanded form: Three hundred twenty-six thousand, five hundred eight and nine hundredths?
Answer: 300,000 + 20,000 + 6,000 + 500 + 8 + 0.09
The required expanded form of three hundred twenty-six thousand, five hundred eight and nine hundredths, 300,000 + 20,000 + 6,000 + 500 + 80 + 0.09.
Given that,
To determine the expanded form: Three hundred twenty-six thousand, five hundred eight and nine hundredths.
A number system is described as a technique of composing to represent digits. It is the mathematical inscription for describing the numbers of a given set by using numbers or other characters in a uniform method. It delivers a special presentation of every digit and describes the arithmetic structure.
Here,
Three hundred twenty-six thousand, five hundred eight and nine hundredths = 326580.09
The expanded form of a number is the sum of the digit with the intrinsic value of the digit placed in the number,
Expanded form = 300,000 + 20,000 + 6,000 + 500 + 80 + 0.09.
Thus, the required expanded form of three hundred twenty-six thousand, five hundred eight and nine hundredths, 300,000 + 20,000 + 6,000 + 500 + 80 + 0.09.

If the value the discriminant is exactly 0, what is true about the graph of the quadratic equation?
The truth about the graph of the quadratic equation would be the vertex of the parabola connects the x-axis when the value of the discriminant is exactly zero.
What is a quadratic equation?The quadratic equation is defined as a function containing the highest power of a variable is two.
When discriminant D of a quadratic equation,
D = 0
Roots are equal and real
D > 0
Roots are real and different
D < 0
Roots have not existed.
When the discriminant is zero, there is only one real root to the quadratic equation. In other words, only the vertex of the parabola connects the x-axis. The vertex is the parabola's base.
Therefore, the truth about the graph of the quadratic equation would be the vertex of the parabola connects the x-axis when the value of the discriminant is exactly zero.

Do these pairs of values (x and y) represent two quantities that are
proportional?
A. Yes, because as x increases, y increases.
B. No, because not all of the pairs represent the same ratio.
C. Yes, because the ratios į and i are equal.
O D. No, because not all of the pairs are simplified ratios.
Answer: B) No, because not all of the pairs represent the same ratio
For each row, divide y over x
Row 1: y/x = 5/3 = 1.67 approximately
Row 2: y/x = 7.4 = 1.75
Row 3: y/x = 10/6 = 1.67 approximately
Row 4: y/x = 15/9 = 1.67 approximately
We see that row 2 has a ratio different from the others. If we were able to ignore this row, then the answer would be "yes x and y are proportional". However, we cannot ignore this row so that's why the answer is choice B.
We want to see if the relationship between x and y is proportional or not.
We will see that the correct option is B:
"No, because not all of the pairs represent the same ratio."
Let's see how to solve this.
First, a proportional relationship is something of the form:
y = k*x
Where k is the constant of proportionality.
So to see if the relationship between x and y is proportional, we can input the pairs on the general proportional relationship.
For the first pair, we have x = 3 and y = 5, then:
5 = k*3
Now we can find the value of k:
k = 5/3 = 1.667
Now let's do the same for the second pair of points, we should get the same constant of proportionality.
7 = k*4
k = 7/4 = 1.75
So we got different constants of proportionality for two different x-y pairs, thus, the relationship is not proportional.
Because k is defined as the ratio between y and x, we can say that the relationship is not proportional because not all of the pairs represent the same ratio.
Thus the correct option is B.

what is the factor of 6a2 – 19a + 10 ???
Answer:
(2a - 5) • (3a - 2)
step by step explanation:
Step-1 : Multiply the coefficient of the first term by the constant 6 • 10 = 60
Step-2 : Find two factors of 60 whose sum equals the coefficient of the middle term, which is -19 .
-60 + -1 = -61
-30 + -2 = -32
-20 + -3 = -23
-15 + -4 = -19 That's it
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -15 and -4
6a2 - 15a - 4a - 10
Step-4 : Add up the first 2 terms, pulling out like factors :
3a • (2a-5)
Add up the last 2 terms, pulling out common factors :
2 • (2a-5)
Step-5 : Add up the four terms of step 4 :
(3a-2) • (2a-5)
Which is the desired factorization
Final result :
(2a - 5) • (3a - 2)

Suppose that under your health insurance policy, hospital expenses are subject to a $750 deductible and $150 per day copay. You get sick and are hospitalized for 4 days, and the bill (after your insurance discounts are applied) comes to $6,250. How much of that hospital bill will you have to pay yourself?
Answer:
$4900
Step-by-step explanation:
It is given that,
According to health insurance policy, hospital expenses are subject to a $750 deductible and $150 per day copay.
If a person hospitalized for 4 days, it would mean that charges will be ($150 × 4 = $600 per day).
Total amount given by insurance policy = $750 + $600 = $1350
The bill for 4 days come out to be $6,250.
The person have to pay ($6,250-$1350) = $4900 itself.
