Answers
Answer:
The cost of the meal should be multiplied by 1.19.---------------------------------------
Let the cost of the meal be x.
Adding a tip of 19%:
x + 19% = x + 0.19x = x (1 + 0.19) = 1.19xAnswer:
Wyatt should multiply with 1.19.
Step-by-step explanation:
Forming the expression,
→ 1 + (19% of 1)
Now the required number is,
→ 1 + (19% of 1)
→ 1 + ((19/100) × 1)
→ 1 + (19/100)
→ 1 + 0.19 = 1.19
Hence, required number is 1.19.

City A and City B had two different temperatures on a particular day. On that day, five times the temperature of City A was 8° C more than three times the temperature of City B. The temperature of City A minus twice the temperature of City B was −4° C. The following system of equations models this scenario: 5x = 8 + 3y x − 2y = −4 What was the temperature of City A and City B on that day? City A was 1° C, and City B was −1° C. City A was 4° C, and City B was 4° C. City A was 7° C, and City B was 9° C. City A was 10° C, and City B was 14° C.
Answers
The temperature of City A and City B on that day was 4° C respectively.
What is a system of equations?A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.
WE have been given system of equations as;
5x = 8 + 3y
x − 2y = −4
Now we can multiply equation B by -5 to eliminate the x variable in both equations.
Add them together;
5x = 8 + 3y
-5x + 10y = 20
Then add both of them A + B:
-5x + 10y + 5x - 3y = 20 + 8
7y = 28
y = 4
To solve for x;
5x = 8 + 3y
5(x) = 8 + 3(4)
x = 4
Hence, the temperature of City A and City B on that day was 4° C respectively.

(I dont have many points as this is a new account but i will mark brainiest if work is shown and correct answer)
Answers
The linear equation that model the above is h = 32 -2t and the height of fire after 8 hours is 16 inches
What is a linear equation?A linear equation is an equation in which the highest power of the variable is always 1. It is also known as a one-degree equation. The standard form of a linear equation in one variable is of the form Ax + B = 0. Here, x is a variable, A is a coefficient and B is constant.
Using the equation for a straight line and writing similar
h = mt + c
h = height, t = hours m and c are constants
at h = 24, t = 4
Equation becomes
24 = 4m + c--------------1
at h = 20, t = 6
20 = 6m + c---------------2
Subtract equation 2 from 1 so that the eqution reduces to
4 = -2m
m = 4/-2
m = -2
substitute m in equation 1
24 = 4( -2) + c
24 = -8 + c
c = 32
substituting m and c in he linear equation above we have
h = 32 - 2t
After 8 hours, the height h = 32 -2(8) which is 16 inches
In conclusion the linear equation is h = 32 - 2t and the height of fire after 8 hours is 16 inches

From the position of the metals on the electrochemical series, there would be no reaction of the solution with iron and copper.

What is the maximum income?Let Q represent the number of cars rented per day and P the rate.
To form the demand equation;
Q = a - bP
A car rental agency rents 440 cars per day at a rate of $40 per day
440 = a - 40b ......1
For each $1 increase in rate, 10 fewer cars are rented
(440-10) = a - (40+1)b
430 = a - 41b ......2
Subtracting equation 2 from 1
10 = b
From equation 1;
440 = a - 10(40)
a = 440 + 400 = 840
So;
Q = 840 - 10P
Cost C = Q×P = P (840-10P) = 840P - 10P^2
Maximum cost is at dC/dP = 0
dC/dP = 840 - 20P = 0
P = 840/20 = $42

The entire missing lengths as well as the missing angles of the given right angle triangle are as calculated below using Pythagoras theorem and trigonometric rules.
How to use trigonometric rules?We are given a right angle triangle and as such we can use both Pythagoras theorem and even trigonometric rules such as sine rule and cosine rules.
a) W are given that A = 30°, Thus;
B = 180 - (90 + 30)
B = 60°
Using sine rule;
a/sin A = b/sin B
a/sin 30 = 6/sin 60
a = 3.464
c/sin 90 = 6/sin 60
c = 6.928
b) a = 13 and b = 13
Using Pythagoras theorem;
c = √(13² + 13²)
c = 18.385
Since a = b, it means it is an isosceles triangle and so;
A = B = 45°
c) B = 30°, c = 10
A = 180 - (30 + 90)
A = 60°
10/sin 90 = b/sin 30
b = 5
10/sin 90 = a/sin 60
a = 8.66
d) A = 45°, c = 12
B = 45°
c/sin 90 = b/sin 45 = a/sin 45
b = a = 12 * sin 45 = 8.485
e) c = 1, b = 1/√2
c/sin 90 = b/sin B
1/sin 90 = (1/√2)/ sin B
B = 45° = A

Answer:
[tex]0.4514 = 45.14%[/tex]
Step-by-step explanation:
Use the equation:
[tex]Z=\frac{X-u}{a}[/tex]
Given:
[tex]u=159, o=13,n=60,s=1.68[/tex]
This is the pvalue of Z when [tex]X = 159+1 = 160[/tex] subtracted by the pvalue of Z when [tex]X = 159-1 = 158[/tex]
[tex]x = 160[/tex]
[tex]Z=\frac{X-u}{o}[/tex]
Central Limit Theorem applied:
[tex]Z=\frac{X-u}{o}[/tex]
[tex]Z=\frac{160-159}{1.68}[/tex]
[tex]Z=0.6[/tex]
[tex]Z=0.6(\text{P-value}:0.7257)[/tex]
[tex]X=150[/tex]
[tex]Z=\frac{X-u}{o}[/tex]
[tex]Z=\frac{158-159}{1.68}[/tex]
[tex]Z=-0.6[/tex]
[tex]Z=-6(\text{P-value}:0.2743[/tex]
[tex]0.7257-0.2743=0.4514[/tex]
This means that there is a 45.14% probability.
Given the function h(x) = -x² - 9x + 23, determine the average rate of change of the function over the interval -8 ≤ x ≤ -2
Answers
The average rate of change of the function h(x) = -x² - 9x + 23, over the interval -8 ≤ x ≤ -2 is 1
What is average rate of change?
The average rate of change of function f over the interval, a ≤ x ≤ b is given by this expression: f(b) - f(a) / b - aIt 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.Let's find the average rate of change of h(x) = -x² - 9x + 23 in the interval of -8 ≤ x ≤ -2
h(-8) = -(-8)² - 9(-8) + 23
= -64 + 72 + 23
= 31
h(-2) = -(-2)² - 9(-2) + 23
= -4 + 18 + 23
= 37
Average rate of change = f(b) - f(a) / b - a
= h(-2) - h(-8)
= 37 - 31 / -2 - (-8)
= 6 / -2 +8
= 6/6
= 1
Here, the average rate of change of the function h(x) = -x² - 9x + 23, over the interval -8 ≤ x ≤ -2 is 1.

Jenny collected donations at a pet store for the local animal shelter. As she left, Jenny
estimated she had collected $85. After counting the donations, she learned she had actually
collected $110. What is the percent error for her estimate?
If necessary, round your answer to the nearest tenth of a percent.
Answers
Answer:
Step-by-step explanation
Initial amount = $85
Final amount = $110
percentage error = ((Final amount - Initial amount)*100)/Final amount
= (25*100)/110
=22.7272
=22.7 (to the nearest tenth of a percent, which is 1 decimal place)
The solution is 22.7 %
The percentage error in the estimation of donations at the pet store by Jenny is 22.7 %
What is Percentage Error?
The difference between an exact value and an approximation to it is the approximation error in a data value. Either an absolute error or a relative error might be used to describe this error.
Percentage error is the difference between the measured value and the true value , as a percentage of the true value
Percentage Error = [ ( | Measured Value - True Value | ) / True Value ]x 100
Given data ,
Let the percentage error be represented as A
Now , the value of A is
The estimated donation amount by Jenny = $ 85
The actual donation amount collected by Jenny = $ 110
Now , the percentage error in the estimation of Jenny A is calculated by the equation ,
Percentage error in the estimation of Jenny A = ( ( | estimated donation amount - actual donation amount collected by Jenny ) | / actual donation amount collected by Jenny ) ) x 100
Substituting the values in the equation , we get
Percentage error in the estimation of Jenny A = ( | 85 - 110 | / 110 ) x 100
On simplifying the equation , we get
Percentage error in the estimation of Jenny A = ( 25/110 ) x 100
Percentage error in the estimation of Jenny A = 2500 / 110
Percentage error in the estimation of Jenny A = 22.72 %
Therefore , the value of A is 22.7 %
Hence , the percentage error in the estimation is 22.7 %
