Which inequality best represents that ice cream at −3°C is cooler than ice cream at 1°C? (4 points)
a
−3°C > 1°C
b
−3°C 3°C
d
1°C < −3°C
Answer:
-3° C < 1°C is the correct option.
Step-by-step explanation:
As we know that:
The inequality symbol '<' means 'less than'.The inequality symbol '>' means 'more than'.If someone says that something is cooler than the other thing, it indicates that it is lesser than the other based on its temperature.
As the ice cream at −3°C is cooler than ice cream at 1°C, it indicates that temperature -3° C < temperature 1°C.
Therefore, -3° C < 1°C is the correct option.

1+12x+40-12x --> distribute
41+0x --> add like terms
1+4(3x+10)-12x = 41 not -9

They have the same area and same perimeter.
They have the same area but different perimeters.
They have different areas but the same perimeter.
They have different areas and different perimeters.
Answer:
they have different areas and different perimeters
The statement that described the areas and perimeters of the figures should be that they have different areas and different perimeters.
What is the perimeter?The perimeter refer to the closed path where it is surrounded, outlines for the two-dimensional shape for the one-dimensional length.
So here the perimeter of a circle should be known as the circumference.
Therefore, they have different areas and different perimeters.

A nutritionist collects data from 25 popular breakfast cereals. For each cereal, the number of calories per serving is plotted on the x-axis against the number of milligrams of sodium on the y-axis. The value of r for the resulting scatterplot is 0.83. Which of the following is a correct interpretation of this value?
a.Each additional calorie is predicted to add approximately 0.83 mg of sodium.
b.There is a positive relationship between calories and sodium. The relationship is weak.
c.There is a positive relationship between calories and sodium. The relationship is strong.
d.As the number of calories increases, the amount of sodium decreases. The relationship is strong.
Answer:
answer C
There is a positive relationship between calories and sodium. The relationship is strong.
Step-by-step explanation:
The following is a correct interpretation of this value is option c. There is a positive relationship between calories and sodium. The relationship is strong.
The Correct interpretation of the value:Since
A nutritionist collects data from 25 popular breakfast cereals.
The value of r for the resulting scatterplot is 0.83.
So based on this, we can say that there should be the positive relationship between calories and sodium.
And, due to this, the relationship is considered to be strong.
Hence the option c is correct.

The measure of the supplement of ∠BAC is (18x+22) degrees. The measure of the complement of ∠BAC is (9x-5) degrees. Determine m∠BAC.
Answer:
∠ABC = 32°
Step-by-step explanation:
We know that the two angles are termed as supplementary when their angle measures add up to 180 degrees.Given that the measure of the supplement of ∠BAC is (18x+22) degrees.
so
∠ABC + (18x + 22)° =180°
∠ABC + 18x =180°-22°
∠ABC + 18x =158°
∠ABC = 158° - 18x ----[Equation A]
We know that the two angles are termed as complementary when their angle measures add up to 90 degrees.Given that the measure of the complement of ∠BAC is (9x-5) degrees.
so
∠ABC + (9x-5)° =90°
∠ABC + 9x =90°+5°
∠ABC + 9x =95°
∠ABC = 95° - 9x ----[Equation B]
Equating [Equation A] and [Equation B]
158° - 18x = 95° - 9x
-18x+9x = 95° - 158°
-9x = -63
divide both sides by -9
x = 7
Now, substituting the value x=7 in the [Equation A]
∠ABC = 158° - 18(7)
= 158° - 126°
= 32°
Thus,
∠ABC = 32°

Which system is most easily solved by graphing and why?
Which system is most easily solved by substitution and why?
Which system is most easily solved by elimination and why?
a. 3m - 4n = 1; 3m - 2n = -1
b. y = 4x - 2; y - 3x = 0
c. y = x; y = -x
Answer:
System A should be solved by elimination because you can easily cancel out the 3m to solve.
System B should be solved by substitution. Since the an equation for the y value is given, you can easily substitute it into the other equation.
System C should be solved by graphing. You don't have to worry about any slopes or intercepts to graph. You can graph it using only whole numbers.

since there are 5,280 feet in one mile and 3.3 feet in one meter how many meters per second are equivalent to 50 miles per hour
Given:
1 mile = 5280 feet
1 meter = 3.3 feet
convert 60 miles per hour to meters per second
60 miles to meters
60 miles x 5280ft x 1meter = (60*5280m)/3.3 = 316800m/3.3
1 mile 3.3ft
= 96,000 meters
1 hour to seconds
1 hour x 60 minutes x 60 seconds = 1 * 60 * 60sec = 3600 seconds
1 hour 1 minute
unit rate: meters per second
96000 meters ÷ 3600 seconds = 26 2400/3600
simplify 26 2400/3600 ⇒ 26 2/3 meters per second
2400 ÷ 1200 = 2
3600 ÷ 1200 = 3
