At 5 a.m., the temperature at an airport was −9.4°F . Six hours later, the temperature was 2.8°F . Which expression represents the total temperature change over the six hours?
I need help with this now!
Answer:
(-9.8 + x) = 2.8
Step-by-step explanation:
The temperature at an airport at 5:00 am was -9.4° F.
Six hours later the temperature was 2.8° F.
Let temperature change in the 6 hours is = x° F
Then the temperature after six hours from -9.8° F will be = (-9.8 + x)° F
And the expression representing the change will be
(-9.8 + x) = 2.8

alexis divided a 1 3/4 pound bag of apples among 3 friends. how many pounds of apples did each friend receive?
Since Alexis divided a 1 3/4 pound bag of apples among 3 friends, the pounds of apples that each friend receives is 7/12 pounds.
Number of pounds of bags of apple to share = 1 3/4
Number of friends to share the apple = 3 friends
Therefore, in order to get the number of pounds of apples that each person gets, we'll need to divide 1 3/4 by 3 and this will be:
= 1 3/4 ÷ 3
= 7/4 ÷ 3
= 7/4 × 1/3
= 7/12
Therefore, the pounds of apples that each friend receives is 7/12 pounds of apple.

A triangle has one angle measuring 3x degrees. A second angle measures 2x + 20 degrees and the third angle measures 4x -20 degrees. What is the value of x
Answer:
20
Step-by-step explanation:
the comment below or above me has everything right except one thing. 4 plus 2 plus 3 equals 9, Not 10. 180 divided by 9 equals 20 and there's your answer
The value of x = 20.
We have the three angles of a triangle.
We have to measure the value of x.
Th sum of all the angles of a triangle is ?The sum of all the angles of a triangle is 180°.
According to the question, we have -
∠1 = 3x
∠2 = 2x + 20
∠3 = 4x - 20
The sum of all the angles of triangle is 180°. Therefore -
3x + 2x + 20 + 4x - 20 = 180
9x = 180
x =20
Hence, the value of x = 20.

A bus service drives passengers between Milwaukee and Chicago every day. They travel from city to city eight times each day. The distance between the two cities is 89 miles..In February there are 28 days. The company's budget allows for 28,000 total miles for February. Do you think the budget is reasonable? Explain
First calculate the total distance covered each day:
distance per day = 89 miles * 8 = 712 miles / day
Then calculate for the whole month (28 days):
distance = 712 miles / day * 28 days = 19,936 miles
Since the actual distance is lesser than the budget, hence it is reasonable.

How do you solve this 2/5c+4-1/5c= -9
Final answer:
To solve the equation 2/5c + 4 - 1/5c = -9, eliminate the fractions and simplify. Find a common denominator, combine terms, and solve for c. The solution is c = 0.
Explanation:
To solve the equation 2/5c + 4 - 1/5c = -9, we need to eliminate the fractions and simplify the equation.
First, find a common denominator for the fractions, which is 5c:
Multiply the entire equation by 5c:2c + 20c - c = -45cCombining like terms:
21c = -45cAdd 45c to both sides:21c + 45c = 0Combine the terms on the left side:
66c = 0;Divide both sides by 66 to solve for c:c = 0Therefore, the solution to the equation is c = 0.
Multiply. 7x3/4 Enter your answer as an improper fraction, in simplified form.
The simplified form of fraction 21/4 is 3 4/7.
We have,
To multiply 7 by 3/4, you can multiply the numerator (7) by the numerator (3) and the denominator (4) by the denominator (1):
= 7 x 3 = 21 (numerator)
= 1 x 4 = 4 (denominator)
So, the result is 21/4.
However, we can simplify this improper fraction further.
Since 21 and 4 have a common factor of 7, we can divide both the numerator and denominator by 7:
21 ÷ 7 = 3 (numerator)
4 ÷ 7 = 4/7 (denominator)
Therefore,
The simplified form of fraction 21/4 is 3 4/7.

A scientist measures the diameter of a bacteria cell and yeast cell. She finds the diameter of a bacteria cell to be 0.0000021 meters and the diameter of a yeast cell to be 0.00000398 meters.
The approximate diameter of the bacteria cell is represented by point ----------
on the number line.
The approximate diameter of the yeast cell is represented by point -----------
on the number line.
The diameter of the bacteria cell is approximately ----------
times smaller than the diameter of the yeast cell.
The approximate diameter of the bacteria cell shows that it would be best represented on the number line by point 2 x 10⁻⁶.
The approximate diameter of the yeast cell is best represented by the point 3 x 10⁻⁶.
Compared to the yeast cell, the approximate diameter of the bacteria cell is approximately 2 times smaller.
What points best represent the diameters of the yeast and bacteria cells?To find the power of 10 that the first whole number needs to be multiplied by, count the number of zeros and the whole number.
The number of zeros and the first whole number for 0.0000021 is 6 so this is the number to multiply 10 by:
= 2 x 10⁻⁶
The same would apply to the number 0.00000398 as there are also five zeros so it becomes:
= 3 x 10⁻⁶
How much larger than the bacteria cell is the yeast cell?You can find this as:
= Diameter of yeast cell / Diameter of bacteria cell
= 0.00000398 / 0.0000021
= 1.89
= 2 approx.

The perimeter of the rectangular base of a monument is 210.5 feet. If the width is equal to its length, what are the dimensions of the base?
The length and the width of the base of the square monument are both 52.625 feet.
Explanation:The question is asking for the dimensions of the base of a monument that has a rectangular shape and a total perimeter of 210.5 feet. Given that the length and width are the same (as it's a square), this implies that both the length and the width of the square are each half of the total perimeter.
We start by dividing the perimeter by 4, as the perimeter of a square is the sum of all four of its sides. So, the length or width of the base of the monument is 210.5 ft / 4 = 52.625 ft.
