I have to study for a test. It's for data management. Does anyone have tips? (Grade 7)
Studying: Use resources.
If your studying for a test, use some resources, like quizizz, quizlet, flashcards, or the internet. If you do, ask your parents for help. Think it like its your big test, and your studying a lot. If you study and try, you'll pass the test on data management. If you need it, ask your teacher for tutoring or practice some data management questions. Studying will help you not to fail a test.
Now, we'll talk about before the test.
Before test: Rest, eat breakfast, and stay calm.
Step-by-step explanation: Going to bed before a test can prevent you from going to sleep. For example, GMAS (for me) is coming soon, and my teacher encourage us to rest, eat breakfast and stay calm. A recommended time for you to go to bed is 8:00-9:30.
Now, about breakfast.
Eating breakfast is also important because you can perform better, in fact, scientists say that if students eat breakfast before a test or exam, they will perform better! Whatever you do, don't skip breakfast. If you do, you won't perform good, and theirs a chance you could fail.
Now, staying calm is the big one.
If your freaking out, stay calm, say a prayer and get your work done! Staying calm is the big one because most students (I am one of them) get worried if they're gonna fail. Keep this in mind: Try. Your. Best. If you don't try, you won't achieve anything. And please don't cheat. If you cheat, you'll have to repeat the whole grade. Can't cheat in college; you'll get kicked out.
During test: DO. NOT. CHEAT.
CHEATING WILL GET YOU KICKED OUT OF COLLEGE AND YOU'LL AUTOMATICALLY FAIL!!! If your computer prevents you from going to other sites, that is good, but don't pull out ANY study guides or notes during your test, unless it's open-notes. If you don't know a questions, skip it and go to the next one. Then go back, it will come to mind later. If your done with your test early, check your answers. Look back and think, "Is this correct?"
Hope you do good on your test!

Answer:
x = 122°
Step-by-step explanation:
since it is a right triangle, the sum of the other 2 interior angles = 90°
the angle opposite x = 90° - 32° = 58°
58° and angle x are supplementary angles. Their sum is 180°.
180° - 58° = 122°
What is the exponential function (0,25) (1,50) (2,100) (3,200) (4,400)
Answer:
Step-by-step explanation:
If it is exponential dividing any term by the preceding term will be a constant, the common ratio or rate. 50/25=100/50...=2 The initial value, a, (at x=0) is 25 so the general form is
y=ar^x we have a=25 and r=2 so
y=25(2^x)
which is a rational number
a) 1.4142135623
b) 3.6256256
c) 2 (pie)

Answer:
Rational numbers can be expressed as a fraction
Squared 5 = 25
25 can be expressed as a fraction- 25/1, so d is correct.

Circumference of a Circle formula:
C = 2πr
C = 2(3.14)(4.4)
C = 6.28(4.4)
C = 27.632
Rounded to the nearest hundredth:
27.63
Answer:
C= 27.63 inches
Step-by-step explanation:
Use the circumference formula C = 2πr.
Subsitute what you are given into the equation and solve.
C = 2πr
C= 2*(3.14)*(4.4inches)
C= 27.63 inches

Part 1: What is the rate of rice to quarts of water for this recipe that uses 4 pounds of rice and 5 quarts of boiling water?
Given:
A recipe uses 4 pounds of rice and 5 quarts of boiling water.
To find:
The rate of rice to quarts of water for this recipe.
Solution:
We need to divide the amount of rice by amount of water to get the rate of rice to quarts of water for this recipe.
[tex]\text{Required rate}=\dfrac{\text{Rice in pounds}}{\text{Water in quarts}}[/tex]
[tex]\text{Required rate}=\dfrac{4}{5}[/tex]
[tex]\text{Required rate}=0.8[/tex]
Therefore, the rate of rice to quarts of water for this recipe is 0.8.

Step-by-step explanation:
There are half coins of 1. 48 coins of 1. It is cost will be 48. And rest are of 50p. 48 coins of 50 p. Therefore it is cost will be 24. The total cost will be 48+24=72.
what is pi and how invented it??
Answer:
Step-by-step explanation:
The Egyptians calculated the area of a circle by a formula that gave the approximate value of 3.1605 for π. The first calculation of π was done by Archimedes of Syracuse (287–212 BC), one of the greatest mathematicians of the ancient world.
Answer:
π is a mathematical constant. Its commonly used value is 3.14. There is a expanded value for π. It appears in many formulas in all areas of mathematics and physics. In maths, it is commonly used for solving of circles and spheres.
The π was invented by Archimedes of Syracuse. He was one of the greatest mathematicians of the ancient world.
Stephanie wants to make 22.5 qt. of a 20%
alcohol solution by mixing together a 6%
alcohol solution and a 36% alcohol solution.
How much of each solution must she use?
Answer:
y = 10.5qt
x = 12 qt
Step-by-step explanation:
0.6x+ 0.36y = 22.5 * 0.2
0.06x + 0.36y = 4.5
x + y = 22.5
x = 22.5 - y
0.06(22.5 - y) + 0.36y = 4.5
1.35 - 0.06y + 0.36y = 4.5
0.3y = 4.5 - 1.35
0.3y = 3.15
y = 3.15 / 0.3
y = 10.5 qt
x = 22.5 - y
x = 22.5 - 10.5
x = 12 qt

A ship leaves the Port of Miami and travels due east toward the Bahamas for 3 miles. The ship turns due south and travels for some distance. The captain then looks back and determines that the ship is directly 10 miles from the starting point at the Port of Miami. How many miles did the ship travel south before the captain checked the distance to the Port of Miami? Round your answer to the nearest tenth. the
What is the distance between (4, 7) and (-8, 3)? Round to the nearest tenth.
Answer:
The distance is approximately 12.6.
Step-by-step explanation:
Moving from (-8, 3) to (4, 7), we see x (the horizontal dimension) increasing by 12 and y (the vertical dimension) increasing by 4. Think of 12 and 4 as the legs of a right triangle whose hypotenuse represents the distance between these two given points.
This distance, from the Pythagorean Theorem, is
d = √(12^2 + 4^2) = √(144 + 16) = √160 = √16√10.
The desired distance is approximately 12.6.

P(x)=0.2x^2+20x-4 where x is the number of units sold. How many units need to be sold for the business to make a profit of $101?
Answer:
5
Step-by-step explanation:
Given the profit equation ;P(x)
x = number of units sold
P(x) = profit made
P(x) = 101
101 = 0.2x^2+20x-4
0.2x^2+20x-4 - 101
0.2x² + 20x - 105 = 0
Using the formula:
-b±[sqrt(b² - 4ac) / 2a]
Where ;
a = 0.2 ; b = 20, c = - 105
Using the quadratic equation solver to save time :
The roots are :
-105 and 5
Items sold cannot be negative ;
Hence, x = units sold = 5
Mariah is replacing the water heater in her home and is considering three different models. One of the things she is comparing is
the volume of the cylindrical storage tank in each water heater. The dimensions of the storage tanks, in inches, are as follows.
• Water Heater X: r= 8.5 and h = 48
• Water Heater Y: r= 9.5 and h = 44
• Water Heater Z: r= 10.5 and h = 32
Which statement is true?
OA. Water heater Y has the storage tank with the greatest volume.
B. Water heater X has the storage tank with the greatest volume.
OC
The storage tanks in all three water heaters have the same volume.
OD
Water heater Z has the storage tank with the greatest volume.
Answer:
A
Step-by-step explanation:
The volume of a Cylinder is [tex]\pi \\[/tex]*r^2 * h
In this problem I will use 3.14 as pi because it is easier to type
Water Tank X: 8.5*8.5*3.14*48=10,889.52
Water Tank Y: 9.5*9.5 *3.14*44=12,469.94
Water Tank Z: 10.5*10.5*3.14*32=11,077.92
So, A is correct.
