2. Gerald was given the following problem to solve for the length of the "?". He has made a mistake in his work. Identify and describe how he made his mistake. Then, solve the problem correctly.
Answers
Answer:
x = 18.7
Step-by-step explanation:
Gerald's answer is almost correct.
He just needs to switch the 14 and the x.
it should be
24/x = 18/14
solve for x by cross multiplication
18x = (24)(14)
18x = 336
x = 18.7

Un objeto tiene una masa de 0.044Lb cuando se sumerge en una probeta que inicialmente contiene 0.350L de agua, el nivel de agua se eleva a 0.485L. ¿Cuál es la densidad (g/mL) del objeto?
Answers
Answer:
147.84 g/L
Step-by-step explanation:
Paso 1
El volumen del objeto se calcula como:
0.485L - 0.350L
= 0.135 litros
Paso 2
Convertimos la masa del objeto de libras a gramos
1 libra = 453.592 gramos
0.044 libras (lb) = x
Cruz multiplicar
x = 0.044 × 453.592 gramos
x = 19.958064 gramos
Paso 3
Densidad del objeto
= Masa (gramos) / Volumen (L)
= 19.958064 gramos / 0.135L
= 147.837511111 g / L
Aproximadamente = 147.84 g / L
Por lo tanto, la densidad (g / mL) del objeto es 147.84 g / L

Fabian harvest 10 pounds of tomatoes from his garden he needs two and 2/5 lb to make a batch of soup if he sets aside 2 and 8/10 lb of tomatoes to make spaghetti sauce how many batches of soup can Fabian make.
Answers
Starting with 10 pounds of tomatoes and taking out the number of pounds he sets aside for spaghetti sauce, 2.8, we have:
10-2.8 = 7.2 pounds left.
0.2 is read as "two tenths," so 7.2 = 7 2/10
We divide this remaining number of pounds by 2 2/5 for each batch of soup:
7 2/10 ÷ 2 2/5
Convert each to an improper fraction:
72/10 ÷ 12/5
Multiply by the reciprocal:
72/10 × 5/12 = 360/120 = 3

What is the Next-Now rule and function rule for this table? 50 POINTS! BRAINLIEST TO CORRECT ANSWER.
Any unrelated answer is subject to getting their IP found and get reported.
Answers
Answer:
Step-by-step explanation:
I'm not sure what the next now rule but I can give you the function.
y = 5 * 2^x
So the table is constructed by letting 0<=x<=8
For example if x is 3
y = 5 * 2^3
y = 5 * 8 = 40
When x = 3 does y come to 40? According to the chart it does.
Try another one
y = 5 * 2*6
y = 5 * 64
y = 320 Is that what the chart records? Yes it does.
If what the text now rule means is that from the current value of y, you can get the next value, then the formula would be
y_n = 2 * y_(n - 1)
y_7 = 2 * y_6
y_7 = 2 * 320
y_7 = 640

The difference quotient is used to determine the average rate of change of g(x) = 5x2 + 6x on the interval from x = 1 to x = 5. Which statement describes the process correctly?
Answers
Answer:
C. The difference quotient is 10x+5h +6, so the average rate of change is 10(1)+ 5(4) + 6 = 36
Step-by-step explanation:
The statement is the difference quotient is 10x+5h +6.
What is average rate of change of function?It is a measure of how much the function changed per unit, on average, over that interval. It is derived from the slope of the straight line connecting the interval's endpoints on the function's graph.
Given function:
g(x) = 5x² + 6x
interval is x= 1 to x=5
so, the average rate of change is
=10(1)+ 5(4) + 6
= 36

please explain i really don’t understand
Answers
Answer:
22.5°
Step-by-step explanation:
First we need to figure out the size of the interior angles on the inside.
The formula of figuring out the total degrees of all the interior angles of any shape is (n-2)×180°.
N is the number of sides.
If we substitute our number of sides (8) we get this:
(8-2)×180°
6×180° = 1080°
Then we divide 1080 by 8 since this is a regular octagon (all angles are equal in a regular shape).
1080° ÷ 8 = 135°
Focusing on the triangle now, we now know that the angle on the tip of the triangle is 135° as it has not been split by the line.
Using the rule of angles in a triangle add up to 180°. We do this sum:
180° - 135° = 45°
There are 2 angles left in the triangle so we do:
45° ÷ 2 = 22.5°
Therefore the angle of x is 22.5°.

Emir flew home from vacation with a heavy bag. With the first airline he flew, Emir had to pay $20 to check his bag, plus $10 for every pound that his bag was over the weight limit. The next flight was with another airline that had the same weight limit. Emir had to pay $5 per pound that his bag was over the weight limit, in addition to the checked bag fee of $30. By coincidence, the fees ended up being the same with both airlines. How large was each airline's fee?
Answers
Answer:
$27.5
Step-by-step explanation:
Let
x = pound over weight limit
Airline 1 = 20 + 10x
Airline 2 = 5 + 30x
Equate the fees
20 + 10x = 5 + 30x
20 - 5 = 30x - 10x
15 = 20x
x = 15/20
x = 0.75 pounds
How large was each airline's fee?
Airline 1 = 20 + 10x
= 20 + 10(0.75)
= 20 + 7.5
= $27.5
Airline 2 = 5 + 30x
= 5 + 30(0.75)
= 5 + 22.5
= $27.5
An airplane is flying at a height of 200m. Its angle of elevation to an observer on the ground is 230. Calculate the distance of the airplane from the observer.
Answers
Answer:
Distance between the plane and the observer is 511.86 miles.
Step-by-step explanation:
From the figure attached,
A plane is flying at point A which is at 200 m height and observer is at point C.
Angle of elevation (∠ACB) of the plane from the observer is 23°.
Let the distance between the observer and the plane is x meters.
By applying sine ratio for angle C,
sin(∠C) = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]
sin(23°) = [tex]\frac{200}{x}[/tex]
x = [tex]\frac{200}{\text{sin}(23)}[/tex]
x = 511.86 miles
Therefore, distance between the plane and the observer is 511.86 miles.
