Quadrilateral CDEF is a parallelogram. solve for x
Answer:
x = 25
Step-by-step explanation:
the consecutive angles in a parallelogram sum to 180° , that is
∠ C + ∠ D = 180
4x + 28 + 52 = 180
4x + 80 = 180 ( subtract 80 from both sides )
4x = 100 ( divide both sides by 4 )
x = 25
On Monday,1 7/8 inches of rain fell. On Tuesday,it rained 1/4 inch. What was the total rainfall for the two days?
Answer:
2.125 inches
Step-by-step explanation:
We Know
On Monday, 1 7/8 inches of rain fell. On Tuesday, it rained 1/4 inch.
1 7/8 = 15/8
What was the total rainfall for the two days?
We Take
15/8 + 1/4 = 15/8 + 2/8 = 17/8 inches of rainfall
17/8 = 2.125
So, the total rainfall for the two days is 2.125 inches.
Answer:
2 1/8 inches
Step-by-step explanation:
You need to add the two amounts of rainfall together to get your answer, which is 1 7/8 + 1/4. To add these fractions, make the fractions equivalent. To find equivalent fractions, we multiply the numerator and the denominator by the same number.
Since 1/4 can be 2/8, you can now add 1 7/8 + 2/8. This equals 2 1/8.
Therefore, the total rainfall for the two days was 2 and 1/8 inches.

Paula’s investments increased by 87.4% in 2020. Those same investments increased by 12.9% in 2012. Calculate the absolute change in the percentage increase amounts from Paula’s investments
the absolute change in the percentage increase amounts from Paula's investments is 74.5%.
What is the percentage?
A percentage that represents a tenth of a quantity. One percent, denoted by the symbol 1%, is equal to one-hundredth of something; hence, 100 percent denotes the full thing, and 200 percent designates twice the amount specified. A portion per hundred is what the percentage denotes. The percentage refers to one in a hundred. The % sign is used to denote it.
The absolute change in the percentage increase amounts is the difference between the two percentages.
Absolute change = |87.4% - 12.9%| = |74.5%| = 74.5%
Therefore, the absolute change in the percentage increase amounts from Paula's investments is 74.5%.

I heard that you might have to increase your prices by 12% if I normally pay $45 per order how much would my order be if the price increase happens the price for your next order would be what
On solving the equation, the price for next order is obtained as $50.40.
What is an equation?
A mathematical definition of an equation is a claim that two expressions are equal when they are joined by the equals sign ("=").
If the price increase is 12%, we need to add 12% of the original price to the original price to get the new price.
So, the new price equation would be -
$45 + 12% of $45
= $45 + 0.12*$45
= $45 + $5.40
= $50.40
Therefore, if the price increase happens, the price for your next order would be $50.40.

How many pizzas must be sold at Pizza Garden in a week for the pizzeria to break even?
Note: The phrase break even refers to the value where the two functions are equivalent. When x is less than the break-even value, the pizzeria has
revenue below expenses, and so it loses money. When x is above the break-even value, the pizzeria has revenue above expenses, and so it makes a
profit.
O 140
O 540
O 3500
O 3520
Answer:
To find the break-even point, we need to set the revenue equal to the expenses and solve for x:
1000 + 18x = 1700 + 13x
5x = 700
x = 140
Therefore, Pizza Garden needs to sell 140 pizzas in a week to break even. So the answer is 140.

Correct option is D. the combined expenses are $300,000 more than the combined income.
What is the bar chart?In business, economics, statistics, and science, bar charts are frequently used to display and compare data. When dealing with data that can be divided into discrete categories, like nominal or ordinal data, they are especially helpful.
According to the Income and expenses graph;
We can verify each options one by one.
A. Expenses have increased $200,000 each year over the last 5 years:
If we see the graph for expenses in each year that is increased by $100,000 not the $200,000 over the last 5 years.
So, the option is wrong.
B. The income in Year 5 was twice the income in Year 1:
Income in year 1 = $600,000
Income in year 5 = $900,000
We can see here, income is not just double.
So, the option is wrong.
C. The sum of all expenses in Years 1, 2, and 3 was the same as the sum of all income in those years:
combined income in Years 1, 2, and 3 = $600,000 + $600,000 + $400,000 = $1600,000
combined expenses in Years 1, 2, and 3 = $400,000 + $500,000 + $600,000 = $1500,000
Both are not equal.
So, the option is wrong.
D. The total amount expenses in Years 3 and 4 were $300,000 more than the total amount income in Years 3 and 4:
combined expenses in Years 3 and 4 = $600,000 + $700,000 = $13,00,000
combined income in Years 3 and 4 = $400,000 + $600,000 = $10,00,000
We can see here the combined expenses are $300,000 more than the combined income.

Infuse 0.8 liters for 9 hours at a drop factor of 60 gtt/ ml. how many ml will be infused per hour
the infusion rate is 88.89 ml/hr or 88.89 gtt/min.
What is Rate?
A rate in arithmetic is a ratio that contrasts two separate values with various unit systems. For instance, if John types 50 words per minute, that means he types 50 words per minute. We are dealing with a rate because the word "per" is there. The symbol "/" can be used in place of the word "per" in issues.
When two or more similar amounts or numbers are being compared using the same units, a ratio is utilized. When referring to the ratio of one quantity "to" the second quantity in spoken language, it is frequently written with a colon.
Next, we can use the formula:
Flow rate (ml/hr) = (Volume infused ÷ Time in hours)
Flow rate (ml/hr) = (800 ml ÷ 9 hours)
Flow rate (ml/hr) = 88.89 ml/hr (rounded to two decimal places)
Finally, we can convert the flow rate from ml/hr to drops per minute (gtt/min) using the drop factor of 60 gtt/ml:
Flow rate (gtt/min) = Flow rate (ml/hr) x Drop factor (gtt/ml) ÷ 60 (min/hr)
Flow rate (gtt/min) = (88.89 ml/hr x 60 gtt/ml) ÷ 60 (min/hr)
Flow rate (gtt/min) = 88.89 gtt/min (rounded to two decimal places)
Therefore, the infusion rate is 88.89 ml/hr or 88.89 gtt/min.

Two people rented a car from the same agency. The first person drove 1010 miles and paid $232.30 for mileage. The
second person drove 765 miles and paid $175.95 for mileage. What is the agency's fee per mile?
The fee of agency's per mile is $0.23 or 23 cents.
Let the fee charged by agency for per mile drive be $x.
It is given that first people drove 1010 miles and charged $232.30 by agency.
So the equation for first person is,
1010x + y = 232.30........... (i), where y is fixed charge by the agency if it is there.
Also given that second person drove 765 miles and paid $175.95 to agency.
So the equation for the second person is,
765x + y = 175.95 ............. (ii)
Subtracting equation (ii) from equation (i) we get,
1010x + y - 765x - y = 232.30 - 175.95
245x = 56.35

The height of an object in motion at time "t" seconds is given by h(t)=-t^2 + 6t +10. Find the maximum height.
The height of the object at any given time t is given by the function h(t) = -t^2 + 6t + 10. To find the maximum height, we need to find the vertex of the parabola described by this function.
The vertex of a parabola in the form y = ax^2 + bx + c is given by the formula (-b/2a, f(-b/2a)), where f(-b/2a) is the y-coordinate of the vertex.
In this case, a = -1, b = 6, and c = 10, so we have:
t = -b/2a = -6/(-2) = 3
To find the maximum height, we need to evaluate h(3):
h(3) = -(3)^2 + 6(3) + 10 = 9 + 18 + 10 = 37
Therefore, the maximum height of the object is 37 units, which occurs when t = 3 seconds.

Triangle ABC ~ triangle DEF. Use the image to answer the question. a triangle ABC with side AB labeled 11, side CA labeled 7.6 and side BC labeled 7.9 and a second triangle DEF with side DE labeled 4.4 Determine the measurement of EF. EF = 3.47 EF = 3.16 EF = 1.39 EF = 1.1
Answer:
FD = 3.16
Step-by-step explanation:
To determine the length of FD, we can use the property of similar triangles that corresponding sides are in proportion to each other. That is,
AB/DE = BC/EF = CA/FD
We are given the lengths of AB, CA, and BC in triangle ABC, and we know that triangle ABC is similar to triangle DEF. We can use the first two sides to find the third side of triangle DEF as follows:
AB/DE = 11/DE = 7.9/EF
=> EF = (DE * 7.9) / 11
Next, we can use the third proportionality to find FD:
CA/FD = 7.6/FD = 11/EF
=> FD = (11 * 7.6) / EF
=> FD = (11 * 7.6) / ((DE * 7.9) / 11)
=> FD = (11^2 * 7.6) / (DE * 7.9)
Now, we just need to substitute the given values and solve for FD:
FD = (11^2 * 7.6) / (4.4 * 7.9)
FD = 3.16
Therefore, the length of FD is 3.16.
