Answer:
B
Step-by-step explanation:
A rhombus is divided into four congruent triangles. The two given angles are complementary, meaning they add up to 90 degrees. Set up an equation:
\((4x-25)+x=90\)
\(4x-25+x=90\) Take out the parentheses
\(5x-25=90\) Combine like terms
\(5x=115\) Add 25 to both sides so as to isolate the variable
\(x=23\) Divide both sides by 5
Answer:
the answer is b or 23

Please help, this assignment will boost my grade up to an A+!
(I have a lot more I need help with too! If you can help. It’s all math)
Answer:
You have to add all the money up then subtract it by the following money you earned.
Step-by-step explanation:
45.35+45.25= 90.5
1.39x75=104.25
0.68x8=5.44
68.72x2=137.44
1.85x37=68.45
0.13x900=117
52.85x12=634.2
52.85x2=105.7
19.49x3=58.47
2750-1321.45=1428.55
(the number 1321.45 came from everything added together, which i then subtracted from 2750 to get 1428.55 as your remaining balance.
Which choice best represents the area of a circle with a diameter of 16 cm. Use ≈3.14
Question options:
256 centimeters squared
803.84 centimeters squared
25.12 centimeters squared
200.96 centimeters squared
Answer:
200.96 centimeters squared
Step-by-step explanation:
16 / 2 = 8
3.14 x 8 x 8
Since the formula is 3.14r^2, you have to divide the diameter into 2 raidiuses to get the circle area.

18/50 as a mixed number
Answer:
2 14/50 simplified to 2 8/25 (all I did was divide 14 and 15 by 2)
Step-by-step explanation:
To convert an improper fraction to a mixed fraction, divide the numerator by the denominator, write down the quotient as the whole number and the remainder as the numerator on top of the same denominator.
How can you tell if an equation has more than one solution?
Answer:
If the equation ends with a false statement (ex: 0=3) then you know that there's no solution. If the equation ends with a true statement (ex: 2=2) then you know that there's infinitely many solutions or all real numbers.
Step-by-step explanation:
I hope this helps you out! :)

James determined that these two expressions were equivalent expressions using the values of x = 4 and x = 6. Which statements are true? Check all that apply.
7 x + 4 and 3 x + 5 + 4 x minus 1
A.When x = 2, both expressions have a value of 18.
B.The expressions are only equivalent for x = 4 and x = 6.
C.The expressions are only equivalent when evaluated with even values.
D.The expressions have equivalent values for any value of x.
E.The expressions should have been evaluated with one odd value and one even value.
F.When x = 0, the first expression has a value of 4, and the second expression has a value of 5.
G.The expressions have equivalent values if x = 8.
Use the best-fit line below to predict the value of y when x = 7
Answer:
the answer is 6 because when x=7 on the line it is also equal to 6 on the y axis

Eric writes 1/3 of a page in 1/5 of a minute. How much time, in minutes, does it take him to write a full page. Type your answer as a fraction. If it is improper, change it to a mixed number.
Answer:
3/5 of a minute
Step-by-step explanation:
1/3 of a page in 1/5 of a minute = 2/3 of a page in 2/5 of a minute = 3/3 (or 1) page in 3/5 of a minute.
Answer:
3/5
Step-by-step explanation:
1 (the goal, or amount of pages) divided by 1/3 (the number of pages he writes per 1/5 minute) = 3
Now, we can't forget that this isn't 3 minutes, it's 3/5 of a minute because you then have to multiply the answer by the time. 3 x 1/5 is equal to 3/1 x 1/5, or 3/5.
So, to summarize, every 1/5 of a minute he writes 1/3 of a page. 1/3 + 1/3 + 1/3 or 1/3 x 3 is equal to 1, or 1 whole page. 1/5 + 1/5 + 1/5 or 1/5 x 3 is equal to 3/5, or the number of minutes.

Tim incorrectly rewrote the expression 1/2p - (1/4p + 4) as 1/2p + 1/2p - 4. Rewrite the expression without parentheses. What was Tim's error?
Answer:
1/2p - 1/4p - 4.
Step-by-step explanation:
1/2p - (1/4p + 4)
= 12p - 1/4p - 4
≠ 1/2p + 1/2p - 4
Instead of writing -1/4p, Tim wrote 1/2p

solve the equation
0.2(d-6)=0.3d+5-3+0.1d for d
Answer:
d= -16
Step-by-step explanation:
To answer this question you'll have to first simplify the equation to
0.2d+-1.2=0.3d+5-3+0.1d
then combining like terms you get
0.2d-1.2=(0.3d+0.1d)+(5+-3)
0.2d-1.2=0.4d+2
then subtract 0.4d from both sides leaving you with
-0.2d-1.2=2
then add 1.2 to both sides
-0.2d=3.2
after you divide both sides by -0.2
leaving you with the answer
D= -16
Answer:
D = -16
Step-by-step explanation:
When multiplying or dividing both sides of an inequality by a negative number, the direction of the inequality symbol is flipped. True or false?
Answer:
true
Step-by-step explanation:
Example:
2 > 1 is true.
Now, multiply both sides by -1.
-2 > -1 is false.
To make the inequality true, after multiplying or dividing by a negative number, you must flip the inequality sign.
-2 < -1 is true.

Answer:
The first option, V ≈ 1607.7 in²
Step-by-step explanation:
Find the volume of the given cylinder.
\(\begin{center}\framebox{\parbox{4cm}{\textbf{Volume of a Cylinder:}\\[2ex]The volume of a cylinder with radius $r$ and height $h$ is given by the formula:\\[2ex]\center{$V = \pi r^2 h$} \\ \\}}\end{center}\)
Given:
r = 8 in
h = 8 in
π = 3.14
Find:
V = ?? in³
\(\hrulefill\)
Now solving,
Substitute the given values into the formula:
=> V = (3.14)(8)²(8)
Using a calculator to simplify:
=> V = 1607.68 in²
Rounded to the nearest tenth:
∴ V ≈ 1607.7 in²
Thus, the first option is correct.

A fruit juice recipe calls for 2 parts orange juice and 8 parts pineapple juice. Which proportion can be used to find the amount of orange juice, j, that is needed to add to 18 L of pineapple juice?
2 over 8 equals j over 18
8 over 2 equals j over 18
8 over j equals 2 over 18
16 over 18 equals j over 100
The correct proportion to use to find the amount of orange juice, j, needed to add to 18 L of pineapple juice is:
2/8 = j/18
This proportion relates the ratio of orange juice to pineapple juice in the recipe (2:8) to the amount of orange juice needed to add to 18 L of pineapple juice. By cross-multiplying, we can solve for j as follows:
2/8 = j/18
218 = 8j
36 = 8*j
j = 36/8
j = 4.5
Therefore, you would need to add 4.5 L of orange juice to 18 L of pineapple juice to create the fruit juice recipe that calls for a ratio of 2 parts orange juice to 8 parts pineapple juice.
Answer:
2 over 8 equals j over 18Step-by-step explanation
2 over 8 equals j over 18
This proportion represents the ratio of orange juice to pineapple juice in the recipe. By setting up the proportion, we can solve for the value of 'j,' which represents the amount of orange juice needed.
So, the correct proportion is:
2 over 8 equals j over 18
