The sum of 85 + w is less than or equal to 6 multiplied by y.
A. 85 + w ≤ 6y
B. 85 + w ≥ 6y
C. 6 x y ≤ 85 + w
D. 85 + w ≠ 6y
Given:
The sum of 85 + w is less than or equal to 6 multiplied by y.
To find:
The inequality for the given situation.
Solution:
We know that,
The sum of 85 and w means "85+w".
Less than or equal means "≤".
6 multiplied by y means "6y".
So, the inequality for the statement "the sum of 85 + w is less than or equal to 6 multiplied by y", is:
[tex]85+w\leq 6y[/tex]
Therefore, the correct option is A.
I need help on this angles on a straight line problem, it involves algebra. I don't need an explanation just the answer please.
Answer:
m<COD = 46°
Step-by-step explanation:
All the angles are supplementary to each other, so we can combine them and set them equal to 180° to solve for x:
(3x+88)°+(x+36)°+(2x-4)°=180°
3x+88+x+36+2x-4=180
6x+120=180
6x=60
x=10
Since we know x=10, then <COD is 10+36 = 46°
Answer:
∠COD = 46°
Step-by-step explanation:
∠AOB (or straight line) = 180°
3x + 88° + x + 36° + 2x - 4° = 180°
combine like terms:
6x + 120° = 180°
subtract 120° from both sides of the equation:
6x = 60°
divide both sides by 6:
x = 10°
∠COD = 10° + 36° = 46°

Step-by-step explanation:
The histogram shows the weights, in pounds, of checked luggage on a flight.
A graph shows weight of a bag (pounds) labeled 12 to 64 on the horizontal axis and number of bags on the vertical axis. 1 bag weighs 12 to 16 pounds. 4 bags weigh 16 to 20 pounds. 5 bags weigh 20 to 24 pounds. 6 bags weigh 24 to 28 pounds. 5 bags weigh 28 to 32 pounds. 4 bags weigh 32 to 36 pounds. 3 bags weigh 36 to 40 pounds. 1 bag weighs 40 to 44 pounds. 0 bags weigh 44 to 48 pounds. 1 bag weighs 48 to 52 pounds. 1 bag weighs 52 to 56 pounds. 1 bag weighs 56 to 60 pounds. 0 bags weigh 60 to 64 pounds.
The median weight of a checked bag is 27.5 pounds. How does the mean of the data most likely compare to the median?
The mean is most likely less than 27 pounds.
The mean is most likely exactly 27.5 pounds.
The mean is most likely about 28 pounds.
The mean is most likely more than 28 pounds.
Answer:
C, the mean is most likely about 28 lbs.
Step-by-step explanation:
The histogram shows the weights, in pounds, of checked luggage on a flight. The median weight of a checked bag is 27.5 pounds.
thats the answer because you are rounding 27.5

Step-by-step explanation:
The hypotenuse of a right triangle is 30 inches. With one of the sides being 18 inches. Find the missing side length. Round to the nearest hundredth if necessary
Answer:
24 inches
Step-by-step explanation:
We can find different sides of a right angle triangle using Pythagorean theorem: [tex]c^2 = a^2+b^2[/tex], where [tex]c[/tex] is the hypotenuse and [tex]a[/tex] and [tex]b[/tex] are the other sides.
Therefore, we can re-arrange the equation for one of the other sides.
[tex]c^2-b^2=a^2[/tex].
Since we know these two sides all we have to do is put them into the equation:
[tex](30)^2-(18)^2=a^2[/tex]
[tex]a^2 = 576\\a= 24[/tex]
Therefore, the missing side is 24 inches.

3. My sister is 12 years older than lam Our combined age is half the age of our
grandfather. Our grandfather is 68 years old. How old am
Answer:
11
Step-by-step explanation:
First, write an equation to represent the situation.
34 = 2a + 12
This equation works because your combined age is half of 68, so 34. If your age is a, then yours sister's age is a + 12. if you add your age to your sister's, you get 2a + 12.
Now just solve for a.
34 = 2a + 12
First, subtract 12 from both sides.
22 = 2a
Then divide both sides by 2.
11 = a
So you are 11 years old. If you need to check your work, your age (11) plus your sister's age (11 + 12, which is 23) is 34, which is half of your grandfather's age.
g(x) is a polynomial that has a leading coefficient of 3, and the following roots -1,1,2. Write g(x) in standard form
The standard form of the polynomial is written as:
p(x) = 3*x^3 - 6*x^2 - 3x + 6
How to write the polynomial in standard form?We know that a polynomial of degree N is with the zeros {x₁, x₂, ...} and a leading coefficient a can be written as:
p(x) = a*(x - x₁)*(x - x₂)*...*(x - xₙ)
In this case, we know that the leading coefficient is 3, and the zeros of the polynomial are {-1, 1, 2}
Then we can write:
p(x) = 3*(x + 1)*(x - 1)*(x - 2)
Now we need to expand that, we will get:
p(x) = 3*(x + 1)*(x - 1)*(x - 2)
p(x) = 3*(x^2 + 1*x + x*(-1) + 1*(-1))*(x - 2)
p(x) = 3*(x^2 - 1)*(x - 2)
p(x) = 3*(x^3 + x^2*(-2) - x + 2)
p(x) = 3*x^3 - 6*x^2 - 3x + 6
That is the polynomial in standard form.

Find the length of ST. Round your answer to the nearest tenth of an inch.
Answer:
7.1
Step-by-step explanation:
Once again we can use trig ratios to solve for ST
First we must recall the trig function
Sin = Opposite over Hypotenuse
Cos = Adjacent over Hypotenuse
Tan = Opposite over Adjacent
We are given the measure of an angle and the length of the hypotenuse
Of the given angle we need to find the adjacent side length
When working with the hypotenuse and adjacent we use trig function cosine
That being said we want to create an equation ( remember cos = adjacent over hypotenuse ) ( let ST = x)
[tex]cos(42)=\frac{x}{9.5}[/tex]
now we solve for x
Step 1 multiply each side by 9.5
[tex]cos(42)*9.5=9.5cos(42)=7.059875842\\\frac{x}{9.5} *9.5=x[/tex]
we're left with x = 7.059875842
Finally we round to the nearest tenth and get that the answer is 7.1
