Final answer:
To determine the number of charms for the bracelet to cost the same at both jewelry shops, we set up a system of equations and solved it using substitution. We found that Hana will need to add 2 charms, resulting in a total cost of $96 for the bracelet at either shop.
Explanation:
To determine the number of charms Hana can add to her bracelet such that the cost is the same at Dayton Fine Jewelry and Cain Jewelers, we need to set up a system of equations and solve using the substitution method.
System of Equations:
Let x represent the number of charms and y represent the total cost of the bracelet with charms.
Equation for Dayton Fine Jewelry: y = 17x + 62
Equation for Cain Jewelers: y = 18x + 60
Solution Using Substitution:
Set the two equations equal to each other since the cost is the same:Hana will need to add 2 charms to her bracelet, and the total cost of the bracelet will be $96 at either jewelry shop.

I need help with pythagoras’ theorem
Answer:
Pythagoras’ theorem is a way to find a side or hypothesis when you have 2 sides.
The formula is: a^2 + b^2 = c^2
a and b are sides
c is the hypothesis
Ex: A triangle has a leg that is 5 inches and a leg that is 7 inches. Find the hypothesis using Pythagoras' theorem.
A leg is another way of saying a side.
5^2 + 7^2 = c^2
25 + 49 = x^2
sqrt(74) = sqrt(x^2)
sqrt(74) inches = hypothesis
Ex: A triangle has a leg that is 9 feet and a hypothesis that is 25 feet. Find the other leg using Pythagoras' theorem.
9^2 + b^2 = 25^2
81 + b^2 - 81 = 625 - 81
sqrt(b^2) = sqrt(544)
b = sqrt(554)

Mr. Lenny paid $1480.00 for 4 cricket balls and 2 cricket bats. The cost of 1 cricket bat is twice as
much as a ball. What is the cost of 1 cricket ball and 1 cricket bat?
Answer.
.
.
.
.
....(
4) (answer with explanation)
Answer:
The cost of one cricket bat is $370, while the cost of one cricket ball is $185.
Step-by-step explanation:
Let's identify what we already know:
1) Mr. Lenny paid a TOTAL of $1480.00 for 4 cricket balls, and two cricket bats.
2) The cost of one cricket bat is twice as much as a cricket ball.
We can create an initial equation:
(4 times x) + (2 times y) = $1480.00
x is the price of one cricket ball, while y is the price of one cricket bat. Considering how the problem is set up, I know the 4 balls should add up to the same price as two bats.
So, the four balls should equal half of $1480, which is $740, and the two bats should also equal $740.
Calculate it out, and you'll find that one cricket bat equals $370, while one ball equals $185.
The question can be solved by representing the cost of a ball as x and bat as 2x, forming the equation 4x + 2(2x) = 1480. Solving this equation finds the cost of the individual cricket ball and bat.
Explanation:In this question, we know that the cost of one cricket bat is twice the cost of a cricket ball, and that Mr. Lenny bought 4 cricket balls and 2 cricket bats for $1480.00. To solve for the individual price of each item, we can use the method of substitution in algebra.
Let's represent the cost of a ball as x and a bat as 2x. This becomes an equation of 4x (cost of 4 balls) + 2(2x) (cost of 2 bats) = 1480.
Solving for x will give us the cost of one cricket ball, and multiplying the value of x by 2 will offer the cost of a single cricket bat.

Which of these statements are correct about a line segment with a length of 12 units in a coordinate plane? Select all that apply.
Correct statements are:
If it is reflected across the y-axis, its length still will be 12 units.
If it is rotated 270° about the origin, its length still will be 12 units.
If it is translated 15 units up, its length still will be 12 units.
Step-by-step explanation:
Whatever it may be rotation, reflection or translation, the size of the line will never change. So length of the line is same as 12 units in the image.
So the wrong statements are
If its reflected across y = -x then the length will no longer be 12 units.
If it is rotated 90° about the origin, then the length will no longer be 12 units.
If it is translated 18 units to the right, then the length will no longer be 12 units.
You can use the fact that reflection, rotation or translation, all three are not modifying the line itself and only its position can change. Whatever be the position, if the line segment itself isn't modified, the length will be same.
Thus, the correct choices are:
Option A: If it is reflected across the y-axis, the length will still be 12 units.Option B: If it is rotated 270° about the origin, its length still will be 12 units.Option E: If it is translated 15 units up, its length still will be 12 units.Rest of the choices are wrong since they blame reflection or rotation or translation to modify the length of that line segment.
Why is the length of a line segment not modified when it is reflected along an axis, rotated or translated by some units in some direction?Suppose you've got a baseball stick. Will it's length change when you take it somewhere else like from your home to playground? No. Will its length change if you hold it upside down? No.
This is the same case with line segment being rotated, reflected, or translated. All these processes do not change the line segment's length and can just move that line segment from one position to other.
Using above conclusion to find the correct options in the given contextSince reflection, rotation, or translation won't affect the length of the line segment,.
Thus, the correct choices are:
Option A: If it is reflected across the y-axis, the length will still be 12 units.Option B: If it is rotated 270° about the origin, its length still will be 12 units.Option E: If it is translated 15 units up, its length still will be 12 units.Rest of the choices are wrong since they blame reflection or rotation or translation to modify the length of that line segment.

5+15x=5( ) I'm not writing 20 characters
Answer:
(1 + 3x).
Step-by-step explanation:
We have to evaluate the missing term within the brackets in the following equation.
The equation is, 5 + 15x = 5(?)
Now, 5 + 15x
= 5 × 1 + 5 × 3x {We have to factorize the term where 5 is a factor}
= 5(1 + 3x) {This is reverse of the distributive property of multiplication}
Therefore, the missing term within the brackets is (1 + 3x). (Answer)

If an intercepted arc measures 124°, what is the measure of its inscribed angle? the same, 124° twice the measure, 248° half the measure, 62°
Answer:
The correct option is C.) half the measure 62°
Step-by-step explanation:
i) Intercepted arc measures 124°
ii) The measure of the inscribed angle will be half of the intercepted arc
therefore inscribed angle = 124° / 2 = 62°
iii) Therefore the correct option is C.) half the measure 62°
The measure of an angle inscribed in a circle is half the measure of its intercepted arc. Therefore, if the intercepted arc is 124°, the inscribed angle would be 62°.
Explanation:This problem is related to the relationship between arcs and inscribed angles in circles. In geometry, there's a specific rule that states: the measure of an angle inscribed in a circle is half the measure of its intercepted arc.
Therefore, if the intercepted arc measures 124°, its inscribed angle would have half the measure, or 62°. If the inscribed angle were to have the same measure, it would imply that the arc measure was double the angle, which is not the case here.

The pet store has 20 mice: 11 are white, five are
grey, and four are brown. If the pet storeowner
randomly chooses a mouse for the window
display, what is the probability that the mouse
will be grey?
Answer:
The answer is: 5/20 or a 25% chance
The probability that the pet store owner randomly selects a grey mouse for the window display is 0.25 or 25%.
Explanation:The question asks for the probability of selecting a grey mouse from a pet store that has a total of 20 mice consisting of 11 white, 5 grey, and 4 brown mice. To find the probability, we use the ratio of the number of grey mice to the total number of mice.
The formula for probability is:
Probability (P) = Number of favorable outcomes / Total number of outcomes
We apply the formula as follows:
P(grey mouse) = Number of grey mice / Total number of mice = 5 / 20 = 0.25 or 25%
Therefore, the probability that the pet store owner selects a grey mouse for the window display is 25%.

suppose you are performing an experiment in science class in which you start with 70 bacteria and the amount of bacteria triples every hour write a function to represent the growth of the bacteria overtime in your science experiment
The function to represent the growth of the bacteria overtime in your science experiment is:
[tex]y = 70(3^x)[/tex]
Solution:
Given that,
Suppose you are performing an experiment in science class in which you start with 70 bacteria and the amount of bacteria triples every hour
Let,
y is the number of bacteria at time x
x is the number of hour(time)
As per the given information,
You start your experiment with 70 bacteria,and the bacteria triples in every hour
Therefore,
At end of 1 hour,
y = 70 x 3 = 210
At the end of 2 hours,
[tex]y = 210 \times 3 = 630\\\\Which\ can\ also\ be\ written\ as\\\\y = 70 \times 3^2 = 70 \times 9 = 630[/tex]
At the end of 3 hours,
[tex]y = 630 \times 3 =1890 \\\\Which\ can\ also\ be\ written\ as\\\\y = 70 \times 3^3 = 70 \times 27 = 1890[/tex]
Thus at end of "x" hours we will have,
[tex]y = 70 \times 3^x\\\\y = 70(3^x)[/tex]
Thus the function to represent the growth of the bacteria overtime in your science experiment
