Step-by-step explanation:
Given 2 secants to a circle from an external point , then
The product of the external part and the whole of one secant is equal to the product of the external part and the whole of the other secant, that is
7(7 + x) = 6(6 + 15) ← distribute left side
49 + 7x = 6 × 21 = 126 ( subtract 49 from both sides )

Find the total payment,
given the cost, sales tax
rate, and tip rate.
Cost: $35.75
Sales Tax Rate: 5%
Tip: 15%
Answers
Answer:
The total payment is thus $35.75 plus $7.11, or $42.86
Step-by-step explanation:
Note that the sales tax doesn't affect the tip. The sales tax is 5% of the cost and the tip is 15% of the before tax cost. We calculate the tax and the tip separately, then add them together and finally add this sum to the cost.
Sales tax: 5% of $35.75: $1.75
Tip: 15% of $35.75: $5.36
Adding these two quantities results in $7.11.
The total payment is thus $35.75 plus $7.11, or $42.86

Where is the mistake
Answers
Answer:
See below
Step-by-step explanation:
Step 2 and Step 3
Mistake #1: From step 1 to step 2 the 32 randomly changed to 9
Mistake #2: According to PEMDAS multiplication and division comes before addition and subtraction.
During step 3, 8 was added to -6 before 8 was multiplied by 7 which is incorrect as the multiplication should come first.
The real answer should be....
-6 +8(11 - 4)+ 32
Evaluate using PEMDAS
Parenthesis
Exponents
Multiplication and division (left to right)
Addition and Subtraction (left to right)
-6 +8(11 - 4)+ 32
First do the operations inside of the parenthesis. ( Subtract 4 from 11 )
-6 + 8(7) + 32
There are no exponents so we go to the next step.
Next is multiplication.
Multiply 8 and 7
- 6 + 56 + 32
Finally we do the addition and subtraction going left to right.
First add 56 to -6
50 + 32
Then add 50 and 32
= 82
Answer: Step 2 and Step 3.
From step 1 to step 2 the "32" unexpectedly changes into a "9" for no reason.
Step 3 also has a mistake due to misusing PEMDAS, as 6 is removed from the 8(7) to get 2. The 6 should be removed from the 32 instead.
Correct step-by-step explanation:
[tex]-6 + 8(11-4) + 32\\=-6+8(7)+32\\=-6+8(7)+32\\=8(7)+26=56+26\\=82[/tex]
Xochitl went to the store to buy some cherries. The price per pound of the cherries is $4 per pound and she has a coupon for $3.50 off the final amount. With the coupon, how much would Xochitl have to pay to buy 3 pounds of cherries? Also, write an expression for the cost to buy pp pounds of cherries, assuming at least one pound is purchased
Answers
Explanation:
4$ per pound
3.5$ coupon
If he buy 3 pound he would need to pay 12$ but since he a 3.5$ coupon thus 12 - 3.5 = 8.5$
Can also written as an expression:
4x - 3.5 = x
Where x determine the amount of pound that is bought.
Xochitl needs to pay $8.50 to buy 3 pounds of cherries.
The expression for the cost to buy p pounds of cherries would be
$(4p - 3.50)
What is an equation?An equation is written in the form of variables and constants separated by the operation of multiplication and division,
An equation states that terms in different forms on both sides of the equality sign are equal.
Multiplication and division do not separate the terms of an equation.
Given, The price per pound of the cherries is $4 per pound and she has a coupon for $3.50 off the final amount.
Therefore, The cost of 3 pounds of cherries before the discount would be,
= $(3×4).
= $12.
And after the discount, it would be $(12 - 3.50).
= $8.50.
An expression for the cost to buy p pounds of cherries would be,
= $(4p - 3.50)

The production has been made more efficient, and eventually the curve will shift inward.
It is not possible for the production to move inside the curve.
Answers
When production is inside the production possibilities curve, it means that the production is not maximized because some resources are unused.
A production possibility curve shows how an economy can be able to produce two goods while making use of the resources that it has. It follows the principle of trade off because as the production of a particular good is increased, the other good has to be reduced.
Production on the production possibility curve shows that the economy is making efficient use of the resources that it has.
When the production is inside the production possibility curve, it means such economy isn't making efficient use of the resources that it has.
Therefore, the correct option is A.

there are nickels, dimes, and quarters in a piggy bank. altogether, the coins are worth $3.65. the number of dimes is three times greater than the number of nickels, and the number of quarters is one greater than double the number of nickels. how many quarters, nickels, and dimes are there?
Answers
Answer:
4 nickels
12 dimes
9 quarters
Step-by-step explanation:
x = number of nickels
y = number of dimes
z = number if quarters
0.05×x + 0.1×y + 0.25×z = 3.65
y = 3x
z = 2x + 1
0.05x + 0.1×3x + 0.25×(2x + 1) = 3.65
5x + 30x + 25×(2x + 1) = 365
35x + 50x + 25 = 365
85x = 340
x = 340/85 = 4
y = 3×4 = 12
z = 2×4 + 1 = 9

The rule that makes a relation NOT a function is if there are shared x values. This function has 2 points with the same x value:
(7, 4) and (7, 6). The sharing of these x-values (or the repeating of them) within the same relation makes this NOT a function. The last choice is the one you want. Just remember that a relation is only a function if there are no shared x-values. The y-values don't matter to this at all. A relation would be a function if it were made up of the following coordinates:
(1, 2), (2, 2), (3, 2), (4, 2), (5, 2), etc. Again, as long as the x-values don't repeat, the relation is a function.

Answer: r = 15/11
Step-by-step explanation:
Given
16 - 2r = 3r + 6r + 1
Combine like terms
16 - 2r = 9r + 1
Add 2r on both sides
16 - 2r + 2r = 9r + 1 + 2r
16 = 11r + 1
Subtract 1 on both sides
16 - 1 = 11r + 1 - 1
15 = 11r
Divide 11 on both sides
15 / 11 = 11r / 11

Luis reads the temperature of a solution in a lab experiment. The temperature of the solution is 5.6º F. After 6 hours, he reads the temperature of the solution again. The temperature of the solution is now −1.2°F .
Luis plots the points on the number line to determine the temperature change between these two readings.
What is the temperature change?
ANSWER:____° F
Answers
The temperature change after 6 hours is 6.8°F
Initial temperature = 5.6°F
Initial temperature = 5.6°FFinal temperature after 6 hours = -1.2°F
The temperature change can be calculated as the difference in the value of final and initial temperature.
Temperature change = (final temperature - initial temperature)
Temperature change = (5.6 - (-1.2))°F
Temperature change = (5.6 + 1.2)°F = 6.8°F
Hence, temperature change after 6 hours is 6.8°F
