1 and 2 are complementary angles. The measure of 1 is 54 . The measure of 2 is 6(x +1). Find the value of x.
Answer:
x = 5
Step-by-step explanation:
Complementary angles are two angles that add up to 90 degrees. 90 - 54= 36, so 6(x+1), or 6x+6 = 36. You subtract 6 from both sides to get 6x=30, then divide by 6 on both sides to get x=5. So the answer would be x=5.

You are buying decorations for a birthday party. Six rolls of crepe paper and 20 balloons cost $11.90. After you start decorating, you need more supplies. You buy 2 more rolls of crepe paper and 15 more balloons for $6.05.
Answer: $1.15
Step-by-step explanation:
The question is How much did each roll of crepe paper cost?
Let the cost of crepe paper be x
Let the cost of balloons be y.
Six rolls of crepe paper and 20 balloons cost $11.90. This will be:
6x + 20y = 11.90 ......... i
2 more rolls of crepe paper and 15 more balloons for $6.05. This will be:
2x + 15y = 6.05 ......... ii
6x + 20y = 11.90 ......... i
2x + 15y = 6.05 ......... ii
Multiply equation i by 15
Multiply equation ii by 20
90x + 300y = 178.50 ........ iii
40x + 300y = 121 ........ iv
Subtract iv from iii
50x = 57.50
x = 57.50/50
x = 1.15
Therefore, a crepe paper cost $1.15

In the process of milling grain, 3% of the original is lost because of spillage,
and another 5% of the originalis lost because of mildew. If the inill starts out
with 490 tons of grain, how much in tons) reinains to be sold after milling?
Answer:
450.8 tons of grain remain to be sold after milling.
Step-by-step explanation:
We know that in total 8% of the original grain is lost (3% spillage + 5% mildew). We can multiply the original 490 tons by 8% to find out how many tons are lost.
490 × 8% ----> 490 x 0.08= 39.2 tons.
We now know that 39.2 tons are lost. We subtract this from the original to see how much remains.
490 - 39.2= 450.8 tons.
We have 450.8 tons remaining.
What does the abbreviation CD stand for?
The abbreviation CD stands for "Compact Disc."
A compact disc is a small, portable, round disc that is used for storing and playing back digital audio, video, and other types of data. It was introduced in the early 1980s as a replacement for vinyl records and cassette tapes.
A CD is made up of a polycarbonate plastic layer that is coated with a reflective metal layer and protected by a clear plastic layer. Information is stored on the disc in the form of tiny pits and lands that are read by a laser beam in a CD player or computer CD-ROM drive.
CDs have a storage capacity of up to 700 MB, which allows for around 80 minutes of audio or several hours of compressed video. They are commonly used for storing music albums, software programs, and other types of multimedia content.
In addition to audio CDs, there are also CD-ROMs (read-only memory), CD-Rs (recordable), and CD-RWs (rewritable). CD-ROMs are pre-recorded discs that cannot be modified, while CD-Rs and CD-RWs can be burned or written with data by the user. CD-Rs can only be written once, while CD-RWs can be erased and re-written multiple times.
Overall, the abbreviation CD refers to the Compact Disc, a versatile medium for storing and playing back digital data.

At age 20, William starts a career with a salary of $40,000 and a promise of a yearly raise of 2%. Approximately how much money will he make over 10 years?
Answer:
8759.78
Step-by-step explanation:
cause by the end of the 10 years he would have 48759.77 minus that by 40,000 you would get 8759.78
Approximately how much money will he make over 10 years is $8,759.78.
Using this formula
Amount=[Principal(1+rate)^t]- Principal
Where:
Principal=$40,000
Rate=2%
Time=10 years
Let plug in the formula
Amount=[$40,000×(1+0.02)^10]-$40,000
Amount=[$40,000×(1.02)^10]-$40,000
Amount=$48.759.776-$40,000
Amount=$8,759.776
Amount=$8,759.78 (Approximately)
Inconclusion approximately how much money will he make over 10 years is $8,759.78.

The perimeters of a square and a rectangle are equal. One side of the rectangle is 11 cm and the area of the square is 4 cm2
more than the area of the rectangle. Find the side of the square.
The answer is X= 9 cm or X= 13 cm
Step-by-step explanation:
Let x=one side of the square; y=one side of the rectangle:
The perimeters are equal, so 4x=2y+22, or y=2x-11. The areas are given by x^2, and 11(2x-11). Since the square is 4 cm^2 larger than the rectangle, we get:
x^2-4=11(2x-11)
x^2-4=22x-121
x^2-22x+117=0
(x-13)(x-9)=0
x=13, or 9
Plugging 13 into our original equation, we get a square 13X13 or 169cm^2, and a rectangle (26-11)X 11, or 165cm^2, which satisfies our requirements!!!!!!

The math team at Felix's school includes students from the sophomores, juniors, and senior classes. Felix wants to create a display to show the percent of students on the math team from each class. Which type of graph best represents the data?
a: stem and leaf plot
b: circle graph
c: line graph
Answer:
B
Step-by-step explanation:
A circle graph also known as a pie chart is used to represent data graphically. the circle graph is made up of a circle that is divided into quadrants. Each quadrants represents different classifications of data and the proportion of each classification.
the sum of angles in a pie chart is 360 degrees while the total percentages is 100%.
If there are 25% of the students in a class each take maths, physics , biology and chemistry, the pie chart would be divided into 4 quadrants with each quadrant measuring 25%
On the SAT exam, a total of 25 minutes is allotted for students to answer 20 math questions without the use of a calculator. A guidance counselor would like to know if the students in his school are prepared to complete this portion of the exam in the time allotted. To investigate, the counselor selects a random sample of 35 students and administers this portion of the test. The students are instructed to turn in their test as soon as they have completed the questions. The mean amount of time taken by the students is 23.5 minutes with a standard deviation of 4.8 minutes. The counselor would like to know if the data provide convincing evidence that the true mean amount of time needed for all students of this school to complete this portion of the test is less than 25 minutes. What are the appropriate hypotheses?
H0: μ = 23.5 versus Ha: μ < 23.5, where μ = the true mean amount of time needed for students of this school to complete this portion of the exam
H0: μ = 23.5 versus Ha: μ > 23.5, where μ = the true mean amount of time needed for students of this school to complete this portion of the exam
H0: μ = 25 versus Ha: μ < 25, where μ = the true mean amount of time needed for students of this school to complete this portion of the exam
H0: μ = 25 versus Ha: μ > 25, where μ = the true mean amount of time needed for students of this school to complete this portion of the exam
Answer:
H0: μ = 23.5 versus Ha: μ < 23.5, where μ = the true mean amount of time needed for students of this school to complete this portion of the exam
The hypothesis is H0: μ = 25 versus Ha: μ < 25, So option (C) is the correct answer.
What is mean and standard deviation?Mean is the ratio of the sum of all the observations and the total number of observations in a data set. The standard deviation is a statistic that measures the dispersion of a data set relative to its mean and is calculated as the square root of the variance.
For the above suituation,
There are 20 math questions to be answered in 25 minutes.
After investigation with 35 students, the meantime needed for them is 23.5 and the standard deviation is 4.8.
From the above information, we can say that the hypothesis, H0: μ = 25 versus Ha: μ < 25, where μ = the true mean amount of time needed for students of this school to complete this portion of the exam.
Hence we can conclude that the hypothesis (C) is the correct answer.
