The percent of increase between the average low and high temperatures
in July would be = 26°F
What is temperature range?Temperature range is defined as the difference between the degree of hotness and coldness of two different places.
The average daily high temperature of the month = 90°F
The average daily low temperature of the month = 69°F
The temperature difference between the two ranges = 90 -69 = 21°F
When both temperature are compared = 90+69/2 = 159/2 = 79.5°F
The percent increase of daily low temperature;
= 21/79.5 × 100/1
= 2100/79.5
= 26.4
= 26°F ( nearest to the tenth place)

Answer:
yes
Step-by-step explanation:
if y = -6,
3x = -6
x = -2
Answer:
yes
Step-by-step explanation:
y = 3x?
Let x = -2 and y = -6
-6 = 3(-2)
-6 = -6
This is a true statement so (-2,-6) is a solution to the equation y = 3x
can you solve 3 5/12 + 1 3/8 ?
Answer:
4 19/24
Explanation:
First, we need to convert the mixed numbers into a fraction, so:
[tex]\begin{gathered} 3\frac{5}{12}=\frac{3\times12+5}{12}=\frac{36+5}{12}=\frac{41}{12} \\ 1\frac{3}{8}=\frac{1\times8+3}{8}=\frac{8+3}{8}=\frac{11}{8} \end{gathered}[/tex]Then, we can add the fractions as follows:
[tex]\frac{41}{12}+\frac{11}{8}=\frac{41(8)+12(11)}{12(8)}=\frac{328+132}{96}=\frac{460}{96}[/tex]Finally, we can simplify the fraction and write the fraction as a mixed number as:
[tex]\frac{460}{96}=\frac{460\div4}{96\div4}=\frac{115}{24}[/tex][tex]\frac{115}{24}=4\frac{19}{24}[/tex]Because when we divide 115 by 24, we get 4 as a quotient and 19 as a remainder.
Therefore, the answer is: 4 19/24

Debbie's checkbook balance was $2,715.50. She wrote checks totaling $5,298.13 during the month of May. Deposits made during the month were $250.16 on May 1. On May 15, her payroll check was electronically processed for $2,980.66; on May 22, a check from the IRS was electronically processed for $2,550. On May 27, she recorded $534.10 for payments debited to her account for auto insurance and utilities. What is her checkbook balance?
Debbie's checkbook balance is $-3,297.23, which shows an overdraft.
When does an overdraft occur?An overdraft occurs when the money (deposits) in Debbie's account does not exceed her payments or withdrawals.
While Debbie had a positive beginning balance, the ending balance shows an overdraft of $-3,297.23.
By this overdraft, Debbie's bank is extending her some short-term credit, which she should pay back with interest.
Beginning balance on checkbook = $2,715.50
Checks for the month = $-5,298.13
Deposits for the month = $250.16
Payroll check = $-2,980.66
IRS check = $2,550
Auto insurance and utilities = $-534.10
Ending balance on checkbook = $-3,297.23
Thus, Debbie's ending checkbook balance will show an overdraft of $-3,297.23.

Given:
650 lb of coffee is sold when the price is $4 per pound,
400 lb of coffee is sold at $8 per pound.
To find:
A) List the data points
B) The slope of line joining the points
C) Interpretation of meaning of slope of line
D) linear equation of data using point slope form
E) Using the function we need to predict the number of consumers buying at $6 per pound
Step-by-step solution:
A) Data points of the given data:
Data points:
(4,650) and (8,400)
B) The slope of the line joining the points:
[tex]\begin{gathered} Slope=\frac{y_2-y_1}{x_2-x_1} \\ \\ Slope=\frac{400-650}{8-4} \\ \\ Slope\text{ =-62.5} \end{gathered}[/tex]C) Interpretation of meaning of slope of line:
Slope here means that:
When there is an increase in the price of coffee then the weight of coffee decreases.
Weight per dollar of coffee decreases at the rate of 62.5
D) linear equation of data using the point-slope form:
Applying point-slope form:
y - y1 = m(x - x1)
y - 650 = -62.5(x - 4)
y = -62.5x + 900
In function notation it can be represented as:
S(P) = -62.5P + 900
E) Using the function we need to predict the number of consumers buying at $6 per pound
To predict that, we will simply put the value of P equal to 6 in the given function:
S(P) = -62.5P + 900 At P = 6
S(P) = -62.5(6) + 900
S(P) = 525
Thus we can say that 525 customers will buy at $6 per pound.

Answer:
x and y is 59 degrees
Step-by-step explanation:
You can find the angle next to 121 which is 59 degrees considering linear pair. Then, you can figure out y by doing corresponding angles and so this means that y is also 59 degrees. To find x, we know that x is vertical to y and that they are the same value. So, this means that x is 59 degrees as well. Hope this helps!

16. A rectangular picture measures 6 inches by 8 inches. Simon wants to build a
wooden frame for the picture so that the framed picture takes up a maximum area
of 100 square inches on his wall. The pieces of wood that he uses to build the
frame all have the same width. Write an equation or inequality that could be used
to determine the maximum width of the pieces of wood for the frame Simon could
create.
Explain how your equation or inequality models the situation.
Solve the equation or inequality to determine the maximum width of the pieces of
wood used for the frame to the nearest tenth of an inch.
Answer:
[tex]w \leq 1.9[/tex]
Step-by-step explanation:
The picture itself measures 6" by 8". Therefore, the area is 6 * 8 = 48 square inches.
All of the pieces of wood have the same width, and we know that two of them will be 6 inches long and two will be 8 inches long.
Therefore, the combined area of the pieces of wood will be 2 * 6w and 2 * 8w. This gives us 12w + 16w.
Now we can set up an inequality:
48 (area of picture) + 12w + 16w <= 100 (maximum area).
Simplify the left side of the equation to give us this:
[tex]48+28w\leq 100.[/tex]
We can move the 48 over to the other side to get [tex]28w \leq 100 - 48[/tex], which simplifies to [tex]28w \leq 56[/tex]. Now, you just have to divide both sides by 28 to get [tex]w\leq 1.857[/tex].
Rounding to the nearest tenth of an inch gives us 1.9 as the maximum width of the pieces of wood.
