The swimming pool is open when the high temperature is higher than 20°C. Lainey tried to swim on Monday and Thursday (which was 3 days later). The pool was open on Monday, but it was closed on Thursday. The high temperature was 30°C on Monday, but decreased at a constant rate in the next 3 days. What is the solution set of the inequality? (also please show the inequality to determine the rate of temperature decrease in degrees Celsius per day, x, from Monday to Thursday.)
Answer: 30° - 3d ≤ 20°
Step-by-step explanation:
Here the constant rate of decreasing the temperature = d degree,
Thus, the total decreasing in three days = 3d degree,
If the temperature on Monday = 30°
Then the temperature n Thursday = 30° - 3d
Since, The swimming pool is open when the high temperature is higher than 20°
⇒ 30° - 3d ≤ 20°
Which is the required inequality to determine the rate of temperature decrease in degrees Celsius per day, d, from Monday to Thursday.
Answer:
30-3d\le 20

10 POINTS) A recipe requires 4.5 teaspoons of sugar to make a cup of pudding. Which equation shows the number of teaspoons of sugar, y, needed to make x cups of pudding?
x = 4.5y
y = 4.5 + x
y = 4.5x
x = 4.5 + y
Answer:
C. y = 4.5x
Step-by-step explanation:
The recipe calls for 4.5 teaspoons of sugar to make each cup of pudding. To make 2 cups of pudding, we would need two groups of 4.5 teaspoons, or 4.5+4.5=9 teaspoons of sugar. To make 3 cups of pudding, we would need 3 groups of 4.5 teaspoons, or 4.5+4.5+4.5=13.5 teaspoons of sugar. This repeated addition can be simplified as multiplication, because 4.5+4.5=4.5*2. We will need y teaspoons of sugar to make x cups of pudding. For each cup of pudding, we need 4.5 teaspoons of sugar. So, y=4.5x. If we made 2 cups of pudding (meaning x = 2 now), we fill that in and solve for y, which equals 9, as seen at the start.
Answer:
C. y = 4.5x

Find the difference. On February 6, 1995, in Sioux Falls, South Dakota, the temperature dropped from 48°F to –16°F in a period of 8 hours. What was the average change in temperature per hour? please help
Answer:
The average change in temperature per hour was -8°F.
Step-by-step explanation:
Using the equation 48-(-16) we know that the temperature dropped by 64°F.
[tex]48-(-16)=64[/tex]
We now know that the temperature dropped by 64°F in a period of 8 hours. Using the equation -64/8 we can find the average change in temperature per hour.
[tex]\frac{-64}{8} = -8[/tex]
Therefore, the average change in temperature per hour was -8°F.

which is largest 3.3 times 10^5 or 3.1 times 10^5
Answer: 3.3 times 10^5 is bigger
Step-by-step explanation: 10^5= 10*10*10*10*10=100,000.
so 100,000 multiplied by 3.3 = 330,000
or 3.1 multiplied by 100,000 = 310,000 so it's obvious that 330,000 is bigger.
The distance around Pauline’s block is 0.96 miles. Which student provides the best estimate for the number of miles she travels if she rides her bike abound the block 13 times?
Enzo. 13 is close to 20. 20 plus 0.96 equals 20.96. Hong. 13 is close to 20. 20 times 0.96 equals 19.20. Maxime. 0.96 is about 1. 13 plus 1 equals 14. Xiu. 0.96 is about 1. 13 times 1 equals 13.
Enzo
Hong
Maxime
Xiu
Answer:
Xiu
Explanation:
0.96 is about 1. 1 represents the length of one time around the block. If she goes around the block 13 times, that is 13 multiplied by 1, which is 13.

At a carnival booth, customers had to guess how many jelly beans were in a jar. Samantha guessed there were 295 jelly beans. There were actually 250 jelly beans in the jar. What is Samantha’s percent error?
Samantha's percent error is 15.24%.
What is Percent Error?
The percent error is the distinction between the estimated value and the actual value in relation to the actual value. In other words, the relative error is multiplied by 100 to calculate the percent error.
Given:
Samantha guessed there were 295 jelly beans.
There were actually 250 jelly beans in the jar.
So, the percent error
= (295- 250) / 295 x 100
= 45 / 295 x 100
= 0.15254 x 100
= 15.24 %

Find the area of a right triangle with a base of 9 feet and a hypotenuse length of 13 feet and a base of 9 feet.(Round to the nearest tenth.)
Answer:
Step-by-step explanation:
Remark
The plan is to find the third side. It and the 9 foot side form a right angle. The base is given as 9 feet. The third sid will be the altitutude. The formula is Area = 1/2 * Base * third side.
Formulas
c^2 = b^2 + a^2
Area = 1/2 b * a
Givens
c = 13 feet
a = ?
b = 9 feet.
Answer: 42.2 square feet.
Solution
c^2 = b^2 + a^2
13^2 = 9^2 + a^2
169 = 81 + a^2 Subtract 81 from both sides.
169 - 81 =81 - 81 + a^2 Combine
88 = a^2 Take the square root of both sides
√a^2=√88
a = 9.381
Area = 1/2 * 9 * 9.381
Area = 42.21
Rounded to the nearest 1/10 Area = 42.2

2 Classify each triangle by its angles and its sides.
Answer:
10) acute triangle
13) right triangle
Step-by-step explanation:
all triangles have angles that add up to 180 degrees
find the third angle of the triangle by subtracting the known angles from 180
180-75-78=27
acute triangles have no angles that surpass 90 degrees which fits that triangle's description
180-54-36=90
since one angle is 90 degrees, it is a right triangle
Answer:
[tex]\huge\boxed{\bf\:10) \: Acute \: angled \: triangle}[/tex]
[tex]\huge\boxed{\bf\:11) \: Right \: angled \: triangle}[/tex]
Step-by-step explanation:
▪︎ Question 10 :
We need to find the missing angle at first. Take it as 'x' .
We know through the angle sum property of a triangle that the total sum of all the angles in a triangle will sum up to 180°. Hence,
75° + 78° + x° = 180°
153° + x° = 180°
x° = 180° - 153°
x° = 27°
Then, since all the angles are less than 90°, we can say that the triangle is an acute angled triangle.
[tex]\rule{150pt}{2pt}[/tex]
▪︎ Question 11 :
Just like the above question, we need to find the missing angle at first. Take it as 'y' .
The total sum of all the angles in a triangle will sum up to 180° (angle sum property of triangles). Hence,
36° + 54° + y° = 180°
90° + y° = 180°
y° = 180° - 90°
y° = 90°
Since, one angle is equal to 90°, the given triangle is a right angled triangle.

1. look at the "x" value in the (x,y) pair
2. if its negetive go leftward and if its positive go rightward
3. once you have moved to the respective x location do the same thing with the y coordinate in the (x,y) pair
4. up is positive for y and down is negitive.
for example (3,3) would be 3 to the right and 3 up so its in the top right quadrent
(-3,-3) would be 3 left and 3 down so its in the bottom left
