Step-by-step explanation:
find the measures of the angles labeled in the figure on the right
Answer:
Step-by-step explanation:
EFD = 90* (straight line = 180, and other angle is 90)
EHF = 180-52 = 128* (again straight line)
HFG = 90-32 = 58* (its a right angle (can tell by the square angle) = 90*)
G = 180 - 52 - 58 = 70* (angles in triangle = 180)
E = 180 - 32 - 128 = 20* (angles in triangle = 180)

Step-by-step explanation:
K(–5, –9); rotation 180° about the origin, translation 3 units left
Answer:
Step-by-step explanation:
Rotate 180 degrees about the origin
X(x,y) ====> X'(-x,-y)
K(-5 , - 9) = K ' (- -5, - - 9)
K' (5,9)
3 Units Left.
y is unchanged.
x becomes x - 3
K'(5,9) ===>k" (5 - 3,9)
k"(2,9)
The leftward motion does not look done the same way as moving a parabola left. But you are just changing the x value to move a point left. You are not imposing other rules on the figure.

you have 120 cows and 90% of them are female how many female cows do you have
Answer: 108
Step-by-step explanation:
If 90% are female, that means that female = 90% of 120, or 90/100 x 120
90/100 x 120 = 108, meaning that there are 108 female cows.
The temperature T of a refrigerator is at least 35°F and at most 41°F. Write a compound
inequality and an absolute value inequality for the temperature of the refrigerator.
The compound inequality for the temperature T of a refrigerator that is at least 35°F and at most 41°F is 35 ≤ T ≤ 41
A compound inequality has two inequality statements joined together
The the temperature of the inequality is represented by T
The temperature T of a refrigerator is at least 35°F and at most 41°F
This means that the temperature falls between 35°F and 41°F
Since the temperature, T, is at most 41°F
This can be mathematically interpreted as
T ≤ 41
The temperature, T, is at least 35°F
35 ≤ T
Combining the two inequality statements 35 ≤ T and T ≤ 41, the compound statement formed is:
35 ≤ T ≤ 41
The compound inequality for the temperature T of a refrigerator that is at least 35°F and at most 41°F is 35 ≤ T ≤ 41

The picture below shows how to solve for the missing values and what each variable is equal to.
How does the perimeter and area change
if each dimension is doubled? Explain!
Answer:
By doubling the dimension R, we'll actually change the area by a factor of 4 (it will become four times as large). Notice that this same change to the radius would only change the original circle's perimeter (2πR) by a factor of 2.

Use the equation to complete an algebraic proof that proves the answer is x = 7/6. Write your proof in your journal and upload your answer. You will be awarded 5 points for the statements and 5 points for the reasons.
2x+65=4x−3
Answer:
Step-by-step explanation:
Show that if 3x – 7 = 5, then x = 4.
Here, our given statement is 3x – 7 = 5, and we're asked to prove x = 4.
x=4
Statements Reasons
1. 3x – 7 = 5 Given
2. 3x – 7 + 7 = 5 + 7 Addition of 7 to equation (1)
3. 3x + 0 = 5 + 7 Substitution of –7 + 7 = 0 into (2)
4. 3x = 5 + 7 Substitution of 3x + 0 = 3x into (3)
5. 3x = 12 Substitution of 5 + 7 = 12 into (4)
6. 3x⁄3 = 12⁄3 Dividing equation (5) by 3
7. x = 12⁄3 Substitution of 3x⁄3 = x into (6)
8. x = 4 Substitution of 12⁄3 = 4 into (7)
Is there such a thing as being too descriptive? Yep, and that was it, since over half the proof was devoted to telling the reader how to do arithmetic. We'll typically take numerical computation for granted, and write proofs like this:
PLEASE HELP WITH PART B!!
can you also explain y and x, I dont understand part B >
A. I would suggest including all units in your answer. Both answers are correct but the unit is also important.
average rate of change:
($750 - $350) / (2014 - 2010) = $400 / (4 years) = $100 per year
initial value:
$350
B. Take 2010 to be year 0. Then for year x = 0, the fee is y = $350.
If the fee increases at a rate of $100 per year, this means that when x = 1, y = $350 + $100 = $450. So the graph of the function that models the dog-walking fee is a line that passes through the points (0, 350) and (1, 450), adn the slope of this line is
(450 - 350) / (1 - 0) = 100/1 = 100
which is the same as the average rate of change.
Using the point-slope formula for a line, the equation you want is then
y - 350 = 100 (x - 0)
y - 350 = 100x
y = 100x + 350

Solve the rational equation x divided by 2 equals x squared divided by quantity x minus 2 end quantity, and check for extraneous solutions.
No solution
x = 0 and x = −2
x = −2; x = 0 is an extraneous solution
x = 0; x = −2 is an extraneous solution
The value of x in the equation [tex]\frac{x}{2} = \frac{x^2}{x - 2}[/tex] are x = 0 and x = -2
How to solve the rational expression?The expression is given as:
[tex]\frac{x}{2} = \frac{x^2}{x - 2}[/tex]
Cross multiply
[tex]x(x - 2) =2 * x^2[/tex]
Open the bracket
[tex]x^2 - 2x =2x^2[/tex]
Collect like terms
[tex]- 2x =2x^2 - x^2[/tex]
Evaluate the like terms

Maggie has a bank account balance of -18.37 as soon as she realizes this she deposits 24.50 in the account
Answer:
correct the answer is 6.13
Step-by-step explanation:
The required current balance in Maggie's bank account is 6.13.
Given that,
Maggie has a bank account balance of -18.37 as soon as she realizes this she deposits 24.50 in the account.
In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication and division,
here,
initial balance in Maggies's bank account = -18.37
She deposited 24.50 in her bank account,
The current balance in her bank account = Initial balance + money deposited
Current = 24.50 - 18.37
Current balance = 6.13
Thus, the required current balance in Maggie's bank account is 6.13.
