Respuesta:
1089,75 kg
Explicación paso a paso:
Dado que :
Masa de embotellado lleno = 1090 kg
Masa de la botella vacía = 250 g
Masa de aceite que contiene la botella:
Expresando la masa de la botella cuando se llena en gramos:
1000 g = 1 kg
1090 kg = (1090 * 1000) = 1090000 g
La masa de aceite que contiene la botella es así:
Masa de la botella cuando está llena - masa de la botella cuando está vacía
1090000 g - 250 g = 1089750 g
Por tanto, la masa de aceite es 1089750 g
O 1089750/1000 = 1089,75 kg

find three numbers that have a mode of 4 and a mean of 6
Answer:
4, 4, 10
Step-by-step explanation:
4, 4, 10
4 appears the most so that's the mode.
Mean = (Sum of numbers)/(3 numbers)
Mean = (4 + 4 + 10)/3
Mean = (18)/3
Mean = 6
The three numbers that have a mode of 4 and a mean of 6 are 4, 4, and 10.
What is mean?
Mean is defined as the ratio of the sum of the number of the data sets to the total number of the data. A set of data values mode is the value that appears the most frequently.
The three numbers that have a mode of 4 and a mean of 6 will be calculated below:-
Let us suppose the three numbers are 4, 4, and 10 the mean will be calculated as:-
Mean = (Sum of numbers)/(3 numbers)
Mean = (4 + 4 + 10)/3Mean = (18)/3
Mean = 6
Therefore, the three numbers that have a mode of 4 and a mean of 6 are 4, 4, and 10.

For Greta's birthday party, her parents ordered 6 pizzas. If they cut the pizzas into sixths, how many pieces will there be? Choose the model that matches this problem.
Options aren't avaible
Answer:
(1 ÷ 1/6) * 6
36 pieces of pizza
Step-by-step explanation:
Given that :
Number of pizzas ordered = 6
Divisions per pizza = 1/6 ;
Hence, 1 full pizza is divided into 1 ÷ 1/6 = 1 * 6/1 = 6 pieces
6 * 1/6(1)
The total pieces of pizzas equals :
6 pieces per pizza * number of pizzas
6 * 6
= 36 pieces of pizza

You invest $1700  in account earning 8% annual interest compounded continuously write an exponential function for the amount in the account after T years
An exponential function for the amount in the account after T years if the interest of 8% is compounding annually on initial amount 1700 is: P_T = 1700(1.08)^T
How to form mathematical expression from the given description?You can represent the unknown amounts by the use of variables. Follow whatever the description is and convert it one by one mathematically. For example if it is asked to increase some item by 4 , then you can add 4 in that item to increase it by 4. If something is for example, doubled, then you can multiply that thing by 2 and so on methods can be used to convert description to mathematical expressions.
How does compound interest works?Instead of calculating the interest on the initial amount, the compound interest repeats calculating interest on (old amount + interest to be paid).
For this case, we're specified that:
Initial amount deposited = $1700Rate of interest = 8% annual = 0.08 (converted percent to fraction).Let P be the inital amount, and r be the rate of interest compounding per unit of time (in decimal)
Let [tex]P_t[/tex] be the amount after t unit of time(same unit as the interest).
Then after 1 year, the new amount would be:
[tex]P_{t+1} = P_t + 100r \%\text{ of }P_t}\\P_{t+1}= P_t + P_t \times r\\P_{t+1} = P_t(1+r)[/tex]
Thus, we get:
[tex]P_t = P_{t-1}(1+r) = P_{t-2}(1+r)(1+r) = P_{t-2}(1+r)^2\\\\P_t = P_{t-t} (1+r)^t = P_0(1+r)^t[/tex]
where P₀ is the initial amount (as amount at t = 0 is initial amount)
Thus, we get:
[tex]P_t = P(1+r)^t[/tex]
Here, putting P = 1700, r = 0.08, and t = T, we get:
[tex]P_T = 1700(1.08)^T[/tex]
Thus, an exponential function for the amount in the account after T years if the interest of 8% is compounding annually on initial amount 1700 is: [tex]P_T = 1700(1.08)^T[/tex]

PEMDAS rule means for the Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This rule is used to solve the equation in a proper and correct manner.
Greg has two coupons for a bicycle.
Coupon A: $19 rebate on an $81 bicycle. Then the price of a bicycle will be
⇒ $81 - $19
⇒ $62
Coupon B: 20% off of an $81 bicycle. Then the price of a bicycle will be

The coordinates of point are (7, 4). Point is a reflection of point across the x-axis. In which quadrant will point W be located
Answer:
Point W will be located on the bottom right quadrant.
Step-by-step explanation:
The x variable becomes negative when reflected across the x-axis.
Answer:
The reflected point will be on the 4th qudrant.
Step-by-step explanation:
So, lets remember what each qudrant is. The first one is (+, +).
The secodn one is (+, -)
The third one is (-,+)
And the fourth one is (-,-)
So looking at this, we instantly know that the orginal point is on qudrant 1. Since our number is +7, +4.
Now we have to flip around the x axis. Well, to the left of the quadrant 1 is qudrant 2. To the bottom of qudrant 1 is qudrant 4. We clearly cannot go to the top or right since there arent any more quadrants, and the qudrant 3 is not accesable with our x and y values.
Remember. we arent going left, since that would be crossing the y axis. This means we have to go down, to the bottom.
What is below qudrrant 1? As I said above, that would be quadrant 4.
Answer:
Quadrant 4
Hope this helps!
