Application for the pythragron theorem.
One Sunday, a 44-minute call cost $2.54. On another Sunday, a 10-minute call cost $0.84. Assume that the cost in dollars of a call, y, is a linear function of the time in minutes, x. Find a linear equation that gives the cost of a Sunday call.
Assume the cost in dollars of a call, y, is a linear function of the time in minutes, the linear equation that gives the cost of a Sunday call is y = 0.05x + 0.34
How to model a linear functionThe linear equation is represented as follows:
y = mx + b
where
m = slope
b = y -intercept
Therefore,
(44, 2.54)(10, 0.84)
m = [tex]\frac{0.84-2.54}{10-44}[/tex]
m = [tex]\frac{-1.7}{-34}[/tex]
m = $0.05
Therefore,
y = cost in dollars
x = time in minutes
0.84 = 0.05(10) + b
0.84 - 0.5 = b
b = 0.34
Therefore,
y = 0.05x + 0.34

Please helz?
The missing number that will make both expressions to be equivalent expressions is: 110.
What are Equivalent Expressions?Two expressions are equivalent if they have the same value.
Given the following expressions:
Expression I: 200r -(-110)Expression II: _ + 200rLet x represent the missing number in the second expression. Thus, equate both expressions and solve for x.
200r -(-110) = x + 200r
200r + 110 = x + 200r
Add like terms
200r - 200r + 110 = x
110 = x
x = 110
Therefore, the missing number that will make both expressions to be equivalent expressions is: 110.

Answer:
For 6, the answer is, x= 65; alternate exterior angles theorem.
For 7, the answer is, x = 17; same-side interior angles postulate
Step-by-step explanation:
I don't have one sorry,
i need the angle measurements for each letter in this image
Answer:
To find c you know that angles on a straight line equal 180° (supplementary angles). So 70+30+∠C=180.
Now we can solve this.
100+c=180.
Move the 100 over to the other side.
100-100+c=180-100
Simplify.
∠C=80°
Because we know that the two lines with double arrows are parallel, we can use the rule that alternate interior angles are congruent. This means that ∠E=70.
∠E=70°
Since the total sum of the angles in a triangle are equal to 180°, we know that ∠D+∠C+∠E=180. Because we already know ∠C and ∠E we can put those numbers in for them. 80°+70°+∠D=180°. Now we can solve this.
80+70+D=180
Simplify this.
150+D=180
Now we move the 150 over to the other side to get D by itself.
150-150+D=180-150
Simplify.
D=30
∠D=30°
Now we can find the vertical angle opposite ∠A by using the alternate interior angles rule again this time using the parallel lines with only one arrow on them. The vertical angle opposite ∠A=30°. Since vertical angles are congruent ∠A=30°.
∠A=30°
We are going to use the alternate angles rule one more time to solve for ∠B (this rule is very important when dealing with parallel lines), we could also use the corresponding angles rule but for simplicity we will just stick with the alternate angles rule. Because the vertical angle opposite ∠A is equal to 30°, we can see that the supplementary angle opposite ∠B=30°. Because this angle is supplementary with B we know that 30+B=180.Now we can solve this.
30+B=180
Now we move the 30 over to the other side.
30-30+B=180-30
Simplify.
B=150
∠B=150°

The vertices of a rectangle are located at the coordinates (2, 2), (2, 6), (5, 6), and (5,2). Find the length of the sides of the rectangle and its perimeter. help meeeee
Answer:
length of rectangle = 4 units
width of rectangle = 3 units
Perimeter of a rectangle = 14 units
Step-by-step explanation:
Properties of a rectangle:
Opposite sides are parallel and equal in lengthEach interior angle is 90°From inspection, we can see that (2, 2) and (2, 6) have the same x-values. So (2, 6) is above (2, 2) on the same vertical line.
To calculate the distance between them, find the difference between their y-values: 6 - 2 = 4
Therefore, one pair of sides of the rectangle are 4 units in length.
From inspection, we can see that (2, 6) and (5, 6) have the same y-values. So (5, 6) is to the right of (2, 6) on the same horizontal line.
To calculate the distance between them, find the difference between their x-values: 5 - 2 = 3
Therefore, the other pair of sides of the rectangle are 3 units in length.
Therefore:
length of rectangle = 4 unitswidth of rectangle = 3 unitsPerimeter of a rectangle = 2 × length + 2 × width
= 2 × 4 + 2 × 3
= 8 + 6
= 14 units
One more: If Ashley intends to leave a 17% tip on a $47 meal, how much will her total bill be?
Answer:
Ashley will have a total bill of $54.99
Step-by-step explanation:
1. Convert percentages into fractions or decimals
For fraction: divide 17 by 100 and remove the % sign.
[tex][17][/tex]%[tex]=\frac{17}{100}[/tex]
For decimal: move the decimal point 2 places to the left and remove the % sign.
[tex][17][/tex]%[tex]=0.17[/tex]
2. Multiply the decimal or fraction by the quantity that equals 100%
100%=47
[tex]17/100*47=0.17*47=7.99[/tex]
So hence, 17% is $7.99 of $47
3. Add the Tip with the Cost of the Meal (will give final answer)
to make things easier -
47+7=54
54+0.99=54.99
So hence, your answer is $54.99----------------------------------------------------------------------------------------------------------

Please help me with this question
Answer:
Using distributive property you jsut multiply the number outside the parenthesis by each number inside.
In this case its
1/2 ( p + 4)
So multiply each number (or variable) by 1/2
And leave the sign if nothing changes
1/2 * p = 1/2p
1/2 * 4 = 2
You’d get
1/2p + 2

And this please, usually I’ll tryy my best to do it without free answers but my teacher hasn’t been on for awhile so we have subs and we don’t do anything but go on Aleks I don’t understand:/
Answer:
Explaining the concept:
We have been given a piecewise function, which means that this function is defined differently for different values
notice that in the function, at the end of each row, we have an 'if' statement
if the input value satisfies the if statement, the function of that respective row will be used
Finding the Values:
h(-5):
since the input value is unequal to -2, the first function will be used (because the if statement at the end of the first function is satisfied by the input value)
h(x) = -(x/4) - (2) (since x ≠ -2)
replacing x with -5
h(-5) = -(-5/4) - 2
h(-5) = (5-8) / 4
h(-5) = -3/4
h(-2):
From the 2 if statements, we notice that this input value satisfies the second statement (x = -2)
Therefore, the second function will be used
h(x) = -1 (for x = -2)
h(-2) = -1
h(0):
This input values satisfies the first if statement.
Hence, the first function will be used
h(x) = (-x/4) - 2 (for x ≠ -2)
replacing x with 0
h(0) = (-0/4) - 2
h(0) = -2
product of 2 and the sum of 4 and x is 22
product = multiplication
so it's 2 * (x+4) = 22
* = product / multiplication
sum = addition
2 * (x+4) = 22
2x + 8 = 22
2x = 14
x = 7

subtract 7/10 - 1/5 simplify your answer
Answer:
1/2
Step-by-step explanation:
7/10 - 1/5
=> 7/10 - 1*2/5*2
=> 7/10 - 2/10
=> (7-2)/10
=> 5/10
=> 1/2
first, you have to make sure they have the same bottom number so you would make 1/5 2/10.
7/10-2/10
which is 5/10
you would simplify it and get 1/2 because 5 is half of 10
