Joaquin recorded a temperature of 62°F this morning for science class. The temperature increased 6 1/2°F in the afternoon before decreasing 8.7°F in the evening. What was the evening temperature?
Answer: [tex]59.8^{\circ} F[/tex]
Step-by-step explanation:
Given : Joaquin recorded a temperature of 62°F this morning for science class.
The temperature increased [tex]6\dfrac{1}{2}^{\circ}F[/tex] in the afternoon before decreasing 8.7°F in the evening.
We can write [tex]6\dfrac{1}{2}[/tex] as [tex]6+\dfrac{1}{2}=6+0.5=6.5[/tex] .
Now According to the question , the temperature at evening will be :-
[tex]62^{\circ}F+6\dfrac{1}{2}^{\circ}F-8.7^{\circ}F\\\\=62^{\circ}F+6.5^{\circ}F-8.7^{\circ}F\\\\=(62+6.5-8.7)^{\circ}\ F=59.8^{\circ}\ F[/tex]
Hence, the evening temperature was [tex]59.8^{\circ} F[/tex] .
Consider the following formula
ax - bx + y = z
which of the following represents the formula that could be used to find x?
A.) x= z-y/a-b
B.) x=a-b/z-y
C.) x= z-y/b-a
D.) x=y-z/b-a
Answer:
The right answer is C I took the assessment
The solution is:
x = (z - y)/(a - b), represents the formula that could be used to find x, from the expression ax - bx + y = z.
What is simplification?Simplify simply means to make it simple. In mathematics, simply or simplification is reducing the expression/fraction/problem in a simpler form. It makes the problem easy with calculations and solving.
here, we have,
given that,
the expression is:
ax - bx + y = z
now, we have to : Solve for x
Subtract y on both sides:
ax - bx = z - y
Factor GCF:
x(a - b) = z - y
Isolate x:
x = (z - y)/(a - b)
Hence, The solution is:
x = (z - y)/(a - b), represents the formula that could be used to find x, from the expression ax - bx + y = z.

the table shows the amount of rainfall in maryville during each week in april what was the total amount if rain in that month of april
The total amount of rainfall in Maryville for the month of April, when expressed as a mixed fraction, is 5 and 1/24 inches. Therefore the correct option is H.
Step 1: Convert mixed numbers to improper fractions
For Week 1, we have 2 2/3 inches, which is a mixed number. We convert it to an improper fraction. Since 2 is equal to 6/3, adding 2/3 gives us 8/3 inches.
Step 2: Sum up the rainfall for all weeks
Now we add the rainfall for each week:
- Week 1: 8/3 inches
- Week 2: 1/8 inches
- Week 3: 1 3/4 inches, which is the same as 7/4 inches when converted to an improper fraction.
- Week 4: 1/2 inches
Step 3: Calculate the total rainfall
The total rainfall for April is the sum of all these amounts.
Let's perform this calculation.
The total amount of rainfall in Maryville for the month of April, when summed up and expressed as an improper fraction, is \( \frac{121}{24} \) inches.
This total is reached by adding the rainfall for each week:
- Week 1's rainfall is [tex]\( \frac{8}{3} \)[/tex] inches.
- Week 2's rainfall is [tex]\( \frac{1}{8} \)[/tex] inches.
- Week 3's rainfall is [tex]\( \frac{7}{4} \)[/tex] inches.
- Week 4's rainfall is [tex]\( \frac{1}{2} \)[/tex] inches.
Adding all these fractions together gives us the total rainfall for the month.
The total amount of rainfall in Maryville for the month of April, when expressed as a mixed fraction, is 5 and [tex]\( \frac{1}{24} \)[/tex] inches.

For your summer babysitting jobs you have 10 weeks to work before your family vacation and before you return to school in the fall. You are planning on earning and saving at least $1500 for your future car. Mrs. Harris is paying you $8.00 an hour to babysit during the day and Mrs. Sanchez is paying you $6.00 per hour to babysit her child in the evening.
• Let x = the number of hours you babysit for Mrs. Harris
• Let y = the number of hours you babysit for Mrs. Sanchez
1. Write an inequality describing the number of hours you want to work each week to reach your summer goal of at least $1500. Remember you have 10 weeks to work. How much do you want to average per week?
The inequality that represents the given situation is (8x + 4y [tex]\geq[/tex] 1500) and this can be determined by using the given data.
Given :
You have 10 weeks to work before your family vacation and before you return to school in the fall. For your future car you are planning on earning and saving at least $1500.$8 per hour is paid by Mrs. Harris.$6 per hour is paid by Mrs. Sanchez.The following steps can be used in order to determine the inequality that describes the number of hours you want to work each week to reach your summer goal of at least $1500:
Step 1 - Let the number of hours you babysit for Mrs. Harris be 'x' and the number of hours you babysit for Mrs. Sanchez be 'y'.
Step 2 - So, the inequality that represents the given situation is given below:
8x + 4y [tex]\geq[/tex] 1500
Now, the average per week can be determined by dividing 1500 by 10. So, you have to make $150 per week.

A student wants to find the density of an egg as part of an experiment. If the weight of the egg is 57 g, and its volume is 48.25 mL, which measurement could be the most precise value of the density of the egg, in g/mL?
The most precise value of the density of the egg will be 1.18 g / mL.
What is Division method?Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications. For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.
Given that;
Weight of the egg = 57 g
Volume = 48.25 mL
Now,
Since, Weight of the egg = 57 g
Volume = 48.25 mL
We know that;
⇒ Density = Mass / Volume
Substitute all the values, we get;
⇒ Density = 57 g / 48.25 mL
= 1.18 g / mL
Thus, The density of the egg = 1.18 g/mL

f as a function of x is equal to the square root of quantity 4 x plus 6, g as a function of x is equal to the square root of quantity 4 x minus 6
Find (f + g)(x). (5 points)
The sum (f + g)(x) of two functions f(x) = √(4x + 6) and g(x) = √(4x - 6) is determined by simply adding the two functions together, hence (f + g)(x) = √(4x + 6) + √(4x - 6).
Explanation:The functions provided are f(x) = √(4x + 6) and g(x) = √(4x - 6). The question asks for the value of (f + g)(x), which is the sum of f(x) and g(x).
To find (f + g)(x), you simply add the two functions together. Hence, (f + g)(x) = f(x) + g(x) = √(4x + 6) + √(4x - 6).
This indicates that the function (f + g)(x) is the addition of the values of f(x) and g(x) at any given value of 'x'.

If the area of a park is exactly between 2.4 and 2.5 acres what is the area of the park?
Answer:
The area of the park is 2.45 acres
Step-by-step explanation:
In order to get a number exactly between other two numbers, you have to add them and then divide that result by two. In a mathematical expression: (a + b)/2, where a and b are those two numbers. In this case, the exactly between 2.4 and 2.5 acres is (2.4 + 2.5)/2 = 2.45 acres.
