a) Combined mass of earth and venues is 10.8 × 10²⁴. b) There are total 18989.2 kg taking earth and venue to equal to the sun.
What is the arithmetic operator?Arithmetic operators are four basic mathematical operations in which summation, subtraction, division, and multiplication involve.,
Summation = addition of two or more numbers or variable
For example = 2 + 8 + 9
Subtraction = Minus of any two or more numbers with each other called subtraction.
For example = 4 - 8
Division = divide any two numbers or variable called division.
For example 4/8
Multiplication = to multiply any two or more numbers or variables called multiplication.
For example 5 × 7.
Given that,
Mass of earth = 5.9 × 10²⁴ kg
Mass of venus = 4.9 × 10²⁴ kg
a) Combined mass of earth and venus
5.9 × 10²⁴ + 4.9 × 10²⁴ = 10.8 × 10²⁴
b) If the mass of the sun = 1.9 × 10³⁰
Let's say the total gain of earth and venus combined x so it will equal the mass.
Then,
10.8 × 10²⁴ + x = 1.9 × 10³⁰
x = 18989.2 kg
Hence "Combined mass of earth and venues is 10.8 × 10²⁴ and there are a total of 18989.2 kg taking earth and venue to equal to the sun.

What is the slope of the line that is represented by the values in the table above?
Answer:
[tex] slope (m) = 6 [/tex]
Step-by-step explanation:
To get the slope of the line of the given table of values, all we need is just 2 coordinate pairs from the table. We can pick any two.
Let's use, (-1, 0), and (0, 6).
Apply the formula, [tex] \frac{y_2 - y_1}{x_2 - x_1} [/tex], where,
[tex] (-1, 0) = (x_1, y_1) [/tex]
[tex] (0, 6) = (x_2, y_2) [/tex]
Thus:
[tex] m = \frac{6 - 0}{0 - (-1)} [/tex]
[tex] m = \frac{6}{1} [/tex]
[tex] slope (m) = 6 [/tex]

The measured height, in feet, of an airplane at certain times, in minutes, after takeoff can be modeled using the regression equation y = StartFraction 29,864 Over 1 + 9.381 e Superscript negative 0.9948 x Baseline EndFraction. To the nearest hundred feet, what is the predicted height of the airplane after 18 minutes?
Answer:
29900 ft
Step-by-step explanation:
just plug in 18 for x
A function assigns the values. The predicted height of the airplane after 18 minutes of takeoff is 29,864 ft.
What is a Function?A function assigns the value of each element of one set to the other specific element of another set.
The measure of the height of an airplane at a certain time is given by the function,
[tex]y = \dfrac{29,864 }{1+9.381 e^{-0.9948x}}[/tex]
where x is the time in minutes and y is the height of the airplane.
Now, the height of the plane after 18 minutes post takeoff can be calculated by substituting the value of time, x as 18 in the function.
[tex]y = \dfrac{29,864 }{1+9.381 e^{-0.9948x}}\\\\y = \dfrac{29,864 }{1+9.381 e^{-0.9948 \times 18}}\\\\y = \dfrac{29,864 }{1+9.381 e^{-7.9064}}[/tex]
[tex]y = \dfrac{29,864 }{1+9.381 e^{-7.9064}}\\\\y = \dfrac{29,864 }{1+(9.381 \times 1.6724 \times 10^8)}\\\\y = \dfrac{29,864 }{1+(1.5689 \times 10^8)}\\\\y = \dfrac{29,864 }{1.000000157}[/tex]
y = 29864 ft
Hence, the predicted height of the airplane after 18 minutes of takeoff is 29,864 ft.

e. misuse of the associative property leads to different results
Step-by-step explanation:
Your calculator (or a spreadsheet) can figure these easily.
a. -12 +(-4 +9) = 12 +5 = -7
(-12 +(-4)) +9 = -16 +9 = -7
__
b. (14 -20) -8 = -6 -8 = -14
14 -(20 -8) = 14 -12 = 2
__
c. (14 +(-20)) +(-8) = -6 -8 = -14
14 +(-20 +(-8)) = 14 +(-28) = -14
__
d. -1 -(-1 +(-1)) = -1 -(-2) = -1 +2 = 1
(-1 -(-1)) +(-1) = (-1+1) -1 = 0 -1 = -1
__
e. The associative property works for addition. When the associative property is used to rearrange subtraction problems, the minus signs need to be kept with the numbers, as in (c). That is, the problem needs to be expressed as a sum of signed numbers.
In (d), the term -(-1 +(-1)) was broken in the middle when the sum was rearranged for the second expression. Only terms in the same level of parentheses can be rearranged by the associative property.

Answer:
74
Step-by-step explanation:
A= Least common multiple of 12,24,36
Factors of 12 = 2*2*3
Factors of 24 = 2*2*2*3
Factors of 36 = 2*2*3*3
A = 2*2*2*3*3 = 72

find the value of x
The answer is 150.
I need to show my work.
THANKSSSS
Answer:
x = 150
Step-by-step explanation:
We know a circle is 360°, so the angles must add up to 60°.
Step 1: Set up equation
x - 120 + x - 120 = 60
Step 2: Solve for x
Combine like terms: 2x - 240 = 60Add 240 on both sides: 2x = 300Divide both sides by 2: x = 150Step 3: Check
Plug in x to verify it is correct.
150 - 120 = 30°
150 - 120 = 30°
30° + 30° = 60°
60° + 300° = 360°
A polling company reported that % of surveyed adults said that Complete parts (a) through (d) below.
a. What is the exact value that is 37% of 1018?
b. Could the result from part (a) be the actual number of adults who said that Why or why not?
1. No, the result from part (a) could not be the actual number of adults who said that because that is a very rare opinion.
2. No, the result from part (a) could not be the actual number of adults who said that because a count of people must result in a whole number.
3. Yes, the result from part (a) could be the actual number of adults who said that because the polling numbers are accurate.
4. Yes, the result from part (a) could be the actual number of adults who said that because the results are statistically significant.
c. What could be the actual number of adults who said that The actual number of adults with this opinion could be 296. (Type an integer or a decimal.)
d. Among the 1018 respondents, 415 said that cellular phones are not at all harmful. What percentage of respondents said that cellular phones are not at all harmful?
Answer:
a) 376.66
b) Option 2: No, the result from part (a) could not be the actual number of adults who said that rising gas prices are "quite annoying" because a count of people must result in a whole.
c) 377
d) 40.77%
Step-by-step explanation:
a) 37% of 1018 is;
37/100 × 1018 = 376.66
b) Thus, the result in a above is not a whole number. Thus;
No, the result from part (a) could not be the actual number of adults who said that rising gas prices are "quite annoying" because a count of people must result in a whole.
c) from a above a, we got a value of 376.66.
Now the actual number would be preferably an integer. Thus, actual number is approximately 377.
d) percentage of respondents said that cellular phones are not at all harmful = 415/1018 × 100% = 40.77%

Step-by-step explanation:
Rational number are the numbers can be written in the form of the fraction [tex]\frac{a}{b}[/tex] , b ≠ 0
Example:
5, -3, 5.2 , -10.567, [tex]2\frac{1}{3}[/tex] , [tex]\sqrt{64}[/tex] , [tex]-\sqrt{\frac{25}{4}}[/tex] , [tex]\frac{\sqrt[3]{8}}{5}[/tex] , .......5 can be written as [tex]\frac{5}{1}[/tex]-3 can be written as [tex]-\frac{3}{1}[/tex]5.2 can be written as [tex]\frac{52}{10}[/tex]-10.567 can be written as [tex]-\frac{10567}{1000}[/tex][tex]2\frac{1}{3}[/tex] can be written as [tex]\frac{7}{3}[/tex][tex]\sqrt{64}[/tex] can be written as [tex]\frac{8}{1}[/tex][tex]-\sqrt{\frac{25}{4}}[/tex] can be written as [tex]-\frac{5}{2}[/tex] [tex]\frac{\sqrt[3]{8}}{5}[/tex] can be written as [tex]\frac{2}{5}[/tex]All the numbers above are rational numbers
Let us find the rational numbers in our question
∵ 0 can be written as [tex]\frac{0}{1}[/tex]
∴ 0 is a rational number
∵ [tex]\frac{5}{7}[/tex] is a fraction
∴ [tex]\frac{5}{7}[/tex] is a rational number
∵ 3.6820350285........ can not be written in the form of the fraction
because we do not know its end (it is an approximated number)
∴ 3.6820350285........ is not a rational number
∵ -10 can be written as [tex]-\frac{10}{1}[/tex]
∴ -10 is a rational number
∴ 0, 5/7, and -10 are RATIONAL numbers

Step-by-step explanation: Uh if Lori has 136 crayons. And rick has 10 more than her He would have 146 And tom has 10 fewer crayons than rick so he would have 136
Lori:136
Rick:146
Tom:136
And idk if u need this or not but if u want it all together it would be: 418
Hope this helps!)
Rick has 146 crayons, Lori has 136 crayons and Tom has 136 crayons'
Let the number of crayons Rick have be x
Let the number of crayons Lori has be y
Let the number of crayons tom has be z
If Rick has 10 more crayons than Lori, then;
x = 10 + y
Since Lori has 136 crayons, hence y = 136
x = 10 + 136
x = 146
If Tom has 10 fewer crayons than Rick, then;
z = x - 10
z = 146 - 10
z = 136
Hence rick has 146 crayons, Lori has 136 crayons and Tom has 136 crayons'
