Answer:
Carla needs to make at least 11 two-pointer shots in the surrent game
Step-by-step explanation:
The first thing we can do is to find the difference between the number of points that Carla scored in her first game and her second game.
This will be 46 - 24 = 22 points difference
Carla needs to make a certain number of two-pointers to get at least the same score she had in her previous game.
We can get this number of two-pointers that needed to be made by dividing the difference in scores by 2
i.e number of two-pointer shots = 22/2 =11 shots
Therefore, Carla needs to make at least 11 two-pointer shots to be able to get the same score in her current game.

Carter stated that 5(x + 9) - 3x is the same as 2x + 45. Lori disagreed with him and said that an equivalent expression is 2x + 9. Who was right?
Answer:
Carter;
5 ( x + 9 ) - 3x = 2x + 45
Step-by-step explanation:
Simplify the equation;
5 ( x + 9 ) - 3x
Distribute the 5, remember, you have to distribute 5 over both terms.
5x + 45 - 3x
Combine like terms;
2x + 45

Element X is a radioactive isotope such that its mass decreases by 81% every year. If an experiment starts out with 490 grams of Element X, write a function to represent the mass of the sample after tt years, where the daily rate of change can be found from a constant in the function. Round all coefficients in the function to four decimal places. Also, determine the percentage rate of change per day, to the nearest hundredth of a percent.
Answer:
We can say we start with 490 grams and after 1 year we have (490 * .81 grams) or 396.9 grams.
We can solve for half-life by this equation:
Half life = (time * log 2) / log (beginning amount / ending amount)
Half-life = (1 year * 0.30102999566) / log (490 / 396.9)
Half life = (1 year * 0.30102999566) / log (1.2345679012 )
Half life = (0.30102999566) / 0.091514981109
Half-Life = 3.2894067399 years
Well, that's a start.
Step-by-step explanation:
The half life of the given radioactive isotope will be 3.2894067399 years.
What is Half life period?
The amount of time it takes to disintegrate by half an initial amount. For a given reaction, a reactant's half-life t-1/2 is the time it takes for its concentration to reach a value which is the arithmetic mean of its initial and final value.
Here, Element X starts with 490 grams
After 1 year we have (490 X 0.81 grams) or 396.9 grams
Now, We can solve for half-life by this equation:
Half life = (time X log 2) / log (beginning amount / ending amount)
Half-life = (1 year X 0.30102999566) / log (490 / 396.9)
Half life = (1 year X 0.30102999566) / log (1.2345679012 )
Half life = (0.30102999566) / 0.091514981109
Half-Life = 3.2894067399 years
Thus, the half life of the given radioactive isotope will be 3.2894067399 years.

can someone plz help me with this question: select the correct answer. what is √125 in simplest form?
Answer: First Option (5√5)
Answer:
First, you see if there are any perfect squares that are a factor of 125. If you do find some, find what is seemingly the biggest. In this case, it is 25, I think. So you can then out it as root(25×5), I think. As 25 is a perfect square, you can square and then put the number you get on the outside. So since 5×5=25, it becomes 5(root)5, which essentially means 5×(root)5, I think.

Answer:
Slope= 4
Step-by-step explanation:
When you start at (0, 0) and then go to (1, 4), then you have to use the slope.
So, to figure out the slope, you have to do rise over run, rise/run.
So, as shown in the graph, the rise is 4 because the rise is the y so to get from 0 to 4, you have to add 4.
And the run, which would be the x side is 1 because to get from 0 to 1. You add 1.
This shows us that the slope is 4/1 which could be simplified to just 4.

Answer:
I don't know how to answer question 1, but the answer from question 2 is x=5
Step-by-step explanation:
The triangle shown is an isosceles triangle because it has two congruent sides. The base angles of isosceles triangles are congruent so ∠y=∠x. since the ∠x is 52 the ∠y is also 52. We subtract the measure of angles x and y in order to find the measure of the third angle. 180-(52+52) or 180-104 is 76. this means that 14x=6=76. All we have to do to get the answer now is solve. 76-6 is 70 and 70 divided by 14 is 5. x=5.

Solve for x using the vertical angles below:
(2 + 3x)
62
Answer:
20
Step-by-step explanation:
Solving for x using the vertical angles we get , the value of x is: x = 20.
Here, we have,
from the given figure we get,
angle (2 + 3x) and angle62 are opposite angles.
we know that,
When two lines intersect each other, then the opposite angles, formed due to intersection are called vertical angles or vertically opposite angles. A pair of vertically opposite angles are always equal to each other.
so, we have,
angle (2 + 3x) = angle62
(2 + 3x) = 62
or, 3x = 60
or, x = 20
Hence, Solving for x using the vertical angles we get , the value of x is: x = 20.

A. 1 /3
B. 3 /4
C. 1 1/6
D. 1 1/3
Dave's rate of completion is 4/3 walls per hour and this can be determined by using the concept of unit rate.
Given :
Dave is hanging dry wall in a house with square rooms. He completes on average 2/ 3 of a wall in 1/2 of an hour.The following steps can be used in order to determine Dave's rate of completion:
Step 1 - The concept of unit rate can be used in order to determine Dave's rate of completion.
Step 2 - According to the given data, Dave completes on average 2/3 of a wall in 1/2 of an hour.
Step 3 - Now, let Dave's rate of completion be 'x'.
Step 4 - So, the value of 'x' can be calculated as:
[tex]x = \dfrac{\dfrac{2}{3}}{\dfrac{1}{2}}[/tex]
Step 5 - Simplify the above expression.
[tex]x = \dfrac{2}{3}\times\dfrac{2}{1}[/tex]
[tex]\rm x = \dfrac{4}{3}\;walls \;per \;hour[/tex]
Therefore, Dave's rate of completion is 4/3 walls per hour.
