(Corresponding angles)
[tex]\therefore(5x - 16)\degree = (2x+50)\degree [/tex]
[tex]\therefore 5x - 16 = 2x+50 [/tex]
[tex]\therefore 5x - 2x = 16+50 [/tex]

Lin opened a lemonade stand during the summer. She
noticed that she sold more lemonade on warmer days.
For each day she sold lemonade, she plotted the point
(t,c), where t represents high temperature and c
represents cups of lemonade sold.
b. A computer program found that the line c= 2t - 89
is a good fit for the data. Use this equation to predict
how many cups of lemonade Lin might sell on a day
when the high temperature is 74 degrees.
c. the high temp this Sunday is expected to be 5 degrees warmer that the high temp this Saturday. using the line c = 2t - 89 how many more cups of lemonade should lin expect to sell on Sunday than Saturday? explain or show your reasoning
Answer:
59 cups ;
10 cups
Step-by-step explanation:
Given that he fitted model :
c = 2t - 89
Where, c = cups of lemonade sold ; t = high temperature
On a day when high temperature is 74 degrees ; cups of lemonade sold
Hence,
c = 2t - 89
c = 2(74) - 89
c = 148 - 89
c = 59 cups
Sunday is expected to be 5 degree warmer than on Saturday :
The number of cups sold on Sunday using the fitted model should be :
Difference in temperature between Saturday and Sunday multiplied by the slope value
Slope value from the model = 2
Temperature difference = 5
Difference in Number of cups :
2 * 5 = 10 cups
Number of lemonade sold on Sunday will be 10 cups more than that sold on Saturday
Answer: 59 cups
Step-by-step explanation:
its 59 cause yea

Write the equations of 2 straight lines which are perpendicular to y = -3x +0.5.
Answer:
y = (1/3)x + 7
y = (1/3)x - 15
These are two examples out of an unlimited number of possibilities.
Step-by-step explanation:
The slope of this given line is -3. Any new line perpendicular to this one is the negative reciprocal of -3: 1/3.
The slope-intercept form is y = mx + b. Here m = 1/3, so the revised form is
y = (1/3)x + b.
Two straight lines perpendicular to the given line are easily found by selecting two different values for b:
y = (1/3)x + 7
y = (1/3)x - 15
Describe the transformations necessary to get from the graph of the parent function f(x)=x? to the
graph of the given function.
G(x)= 2(x - 3)^2 + 9
(Compress,Stretch)the graph vertically by a factor of_______
then translate the graph_______units to the (right,left)and _______ units (down,up)
Answer:
translate the graph 5 units left and down 2 units
Step-by-step explanation:
To translate the function f(x) by an amount h units right and k units up, make the transformation ...
g(x) = f(x -h) +k
Comparing this to your equation,
g(x) = f(x +5) -2
we see that the translation is h = -5, k = -2.
The graph of f(x) is translated 5 units left and 2 units down to make the graph of g(x).

Nadia needs 2/5 cup of orange juice for a punch recipe. She will double the recipe to make punch for a party. Which statement is true?
Answer:
Step-by-step explanation:
There's not a lot to go on with the details provided in the question, but based on all you said, if there isn't more to the question, then the true statement is the fact that Nadia needs 2/5 cup of orange juice for punch recipe.
Twice that amount is 4/5, and logically, that can't suffice in a party, except it's a party of 3, maybe 5 people. I'm assuming the people in the party would be much more than that. Makes the fraction impossible

a card board box has a mass of 1,800 g. When 4 books of equal mass are put into the box, the filled box has a mass of 9 kg. what is the mass of each book in grams
Answer:
You have an empty box which is 1,800 grams. After you put the books in, it's 9 kilograms. There are 9,000 grams in 9 kilograms, and 1,800 grams were already there before you put the books.. so just do 9,000 - 1,800 which equals 7,200. Then divide 7,200 by 4, because there are 4 books with equal mass.
Step-by-step explanation:
I divide 7200by 4 and I got 1800

The areas of two similar squares are 16m2 and 49m2 what is the scale factor of their side lengths
Given:
The areas of two similar squares are 16m² and 49m².
To find:
The scale factor of their side lengths.
Solution:
We know that the ratio of the areas of the similar squares is proportional to the ratio of square of there sides.
[tex]\dfrac{\text{Area of first square}}{\text{Area of second square}}=\dfrac{(\text{Side length of first square})^2}{(\text{Side length of second square})^2}[/tex]
[tex]\dfrac{16\ m^2}{49\ m^2}=\dfrac{s_1^2}{s_2^2}[/tex]
[tex]\dfrac{4^2}{7^2}=\left(\dfrac{s_1}{s_2}\right)^2[/tex]
[tex]\left(\dfrac{4}{7}\right)^2=\left(\dfrac{s_1}{s_2}\right)^2[/tex]
Taking square root on both sides, we get
[tex]\dfrac{4}{7}=\dfrac{s_1}{s_2}[/tex]
[tex]\dfrac{s_1}{s_2}=\dfrac{4}{7}[/tex]
Now, the scale factor is the ratio of side length of second square to the side length of first square.
[tex]k=\dfrac{s_2}{s_1}[/tex]
[tex]k=\dfrac{7}{4}[/tex]
Therefore, the scale factor of their side lengths is [tex]k=\dfrac{7}{4}[/tex].

evaluate tan(sin^-1(-4/5)). Enter your answer as a fraction using the slash bar (/).
Answer:
-1333/1000
Step-by-step explanation:
Evaluate tan(sin^-1(-4/5)).
First we need to evaluate the expression in parenthesis
sin^-1(-4/5)
= sin^-1(-0.8)
= -53.13
SUbstitute the given value into the original expression as shown;
tan(sin^-1(-4/5))
= tan(-53.13)
= -1.333
= -1333/1000
Hence the required answer is -1333/1000

Write an equation that represents the distance d and Miles traveled by the monarch butterfly and t days
Complete question :
When the monarch butterfly is migrating to the south, it has an average speed of 80 miles per day. Write an equation that shows the realtionship between the number of days (t) and the distance (in miles) it has traveled (d)
Answer:
d = 80t
Step-by-step explanation:
Given :
Average speed = 80 miles per hour
Distance traveled (in miles) = d
Number of days = t
Equation which shows the Relationship between Number of days and distance traveled :
Recall :
Speed = distance / time
Speed = 80 ; distance = d ; time = t
80 = d/t
80 * t = d
d = 80t
