find z and x
please help i’ll mark the first one or whoever right brainliest
Answers
Answer:
z=97 x=21
Step-by-step explanation:
so straight angles always equal 180°
And assuming that your lines are parallel, the angle under angle z should be 83° just like the angle above angle z
There for to solve for x, first subtract 83 from 180 because that's what that angle is equal to.
Now that you have the equation 4x+13 and you know that it's equal to 97 you can solve it just like a normal inequality.
4x+13=97
4x=84
x=21

A bakery sells 3642 pastries in 2010. The bakery sells 8422 pastries in 2015. Write a linear model that represents the number y of pastries that the bakery sells x years after 2010
Answers
Answer:
y = 936x + 3742
Step-by-step explanation:
If it is a linear model, then we should have a slope and y-intercept with the equation representing the model as;
y = mx + c
where m is the slope and c is the y-intercept
Thus, we have for the slope;
(8422-3742)/(2015-21010) = 4680/5 = 936
So the equation will be;
y = 936x + c
To get c , we can use the years after 2010 which is 2015 in this case
8422 = 936(5) + c
c = 8422- 4680
c = 3742
So the linear model is;
y = 936x + 3742

I need help on this one
Answers
Answer:13.7
Step-by-step explanation:
The question is asking us to build an algebraic model of this question, to do this, we need to use the slope intercept form.
Let's first identify the known data. We know that a pizza with two toppings is 9.95. In addition, we know that a topping itself is 1.25. We need to find the y intercept first in order to solve this equation, therefore we need to find how much a pizza his without the two toppings. So, we do 1.25(2)=2.5 and subtract it from 9.95. 9.95-2.5= 7.45. Now, this is our y intercept, because this will always stay the same and this is where we always start off. The slope itself however will be 1.25x, because x is the amount of toppings. So, as of now, we have constructed our equation
y=1.25x+7.45
We are looking to see how much a pizza is with 5 toppings, so we plug 5 into x
y=1.25(5)+7.45= 13.7

A store offers four different brands of a product. It decides to eliminate the brand that is most likely to be returned. The table shows the number of items of each brand that were returned over the past year and the total sold. which brand should the store eliminate? A. Brand A B. Brand B C. Brand C D. Brand D
Answers
The brand that the store should eliminate out of the 4 given brands using the data in the table is; Brand C
How to Solve Percentage Problems?To find the brand that the store should eliminate we need to find the percentage of sold items that were returned and pick the highest percentage as the brand the store should eliminate.
Brand A percentage = 33/636 * 100% = 5.19%
Brand B percentage = 15/492 = 3.05%
Brand C percentage = 29/362 * 100% = 8.01 %
Brand D percentage = 32/767 * 100% = 4.17%
Brand C has the highest percentage and as such it is the brand that should be eliminated.

a research lab is to begin experiments with a bacteria that doubles every 4 hours. the lab starts with 200 bacteria. a. how many bacteria will be present at the end of 12th hour? b. how many bacteria will be present at the end of one day? please answer this
Answers
Answer:
A) 1600 bacteria
B) 12800 bacteria
Step-by-step explanation:
We are told that the bacteria doubles every 4 hours.
Now, if the amount of bacteria is X, it means that for 4 hours, it becomes 2X and after 8 hours it becomes 2(2X)
For 12 hours, it becomes; 2 × (2(2X))
This means that for 12 hours, it becomes 2 × (2(2X)) = 8X
A) Since the lab starts with 200 bacteria, after 12 hours, it has;
N_12 = 8 × 200.
N_12 = 1600 bacteria
B) From above, we have seen that after t hours, where t is a multiple of 4, the number of bacteria is;
N_t = [2^(¼t - 1)] × (2X)
Where X is initial amount of bacteria.
Thus, after a day which is 24 hours, we have;
N_24 = 2^(¼(24) - 1) × 2X
N_24 = 2^(5) × 2X
Where X is 200, N_24 = 32 × 2(200) = 12800 bacteria

Point A located at -11 and -7 on the coordinate plan is reflected over the X axis to form point B.Then point B is reflected over the y axis to form point C. What are
the coordinates of points B and C
Answers
Answer:
The coordinates of B are (-11,7)
The coordinates of C are (11,7)
Step-by-step explanation:
Reflection of Points
Given a point (x,y), it can be reflected in several ways. Two of the most-used are reflection over the x-axis and reflection over the y-axis.
When the point is reflected over the x-axis, the x-coordinate is unchanged, and the y-coordinate is inverted: (x,y) -> (x,-y).
When the point is reflected over the y-axis, the y-coordinate is unchanged, and the x-coordinate is inverted: (x,y) -> (-x,y).
Point A is located at (-11,-7). It's reflected over the x-axis to form point B whose coordinates are (-11,7).
Then, point B is reflected over the y-axis to form point C with coordinates (11,7).
The coordinates of B are (-11,7)
The coordinates of C are (11,7)

Neil's bank offered him a 4.95% interest rate for his mortgage. If he
purchases 3 points, what will his new rate be?
O A. 0.375%
O B. 4.575%
C. 1.75%
O D. 4.375%
Answers
Neil's new interest rate after purchasing 3 points would be 7. 95%. The closest option is B. 4.575%.
How to calculate the interest rate?To calculate the new interest rate after purchasing points, we need to know the cost of one point and the number of points purchased.
One point typically costs 1% of the mortgage amount, so three points would cost 3% of the mortgage amount. The cost of the points is usually paid upfront at closing.
Assuming Neil's mortgage amount is $100,000, the cost of 3 points would be:
3% x $100,000 = $3,000
To calculate the new interest rate, we need to add the cost of the points to the original interest rate and then recalculate it as a percentage:
New rate = Original rate + (Cost of points / Mortgage amount)
New rate = 4.95% + ($3,000 / $100,000)
New rate = 4.95% + 3%
New rate = 7.95%
So, Neil's new interest rate after purchasing 3 points would be 7. 95%. The closest option is B. 4.575%.
