Garrys H is one less than three times is Sister's age Girl ❤️ Gary's age is one less than three times is Sister‘s age Girl ❤️ Gary is 11 years old how old is his sister
Answer:
4 years old
Step-by-step explanation:
His sister is x years old.
Gary is 1 year less than 3 times her age, so his age is
3x - 1
His age is 11, so we can write an equation.
3x - 1 = 11
Add 1 to both sides.
3x = 12
Divide both sides by 3.
x = 4

A recipe calls for 2 cups of sugar, 3 cups of flour, 1 cup of butter, and 1/2 a cup of chocolate chips. What is the ratio of flour and butter to sugar?
Answer:
2 : 1
Step-by-step explanation:
Recipe :
Sugar = 2 cups
Flour = 3 cups
Butter = 1 cup
Chocolate chips = 1/2 cup
ratio of flour and butter to sugar?
Total cups of flour plus butter = (3 + 1) = 4 cups
Cups of sugar = 2 cups
ratio of flour and butter to sugar :
4 cups : 2 cups
= 2 : 1
1. How can you tell that a point on the graph is a maximum or minimum?
2. How would you explain average rate of change to a classmate who was absent today? What does it tell us and how do we find it?
please give a simple summary of both answers after the explanations!!

Answer:
there are no points higher than a maximum; no points lower than a minimumaverage rate of change is the slope of a straight line connecting the points of interest.Step-by-step explanation:
1. A point on a graph is a maximum if there are no points on the graph that are higher.
A point on a graph is a minimum if there are no points on the graph that are lower.
Sometimes you're interested in a "local" maximum or minimum. In that case, the "no points higher/lower" rule refers to points in the immediate vicinity of the one of interest.
Sometimes you're interested in a maximum or minimum on an interval. In that case, the rule applies to points contained within the interval. (The maximum or minimum may be at the end of the interval.)
__
2. Average rate of change is defined over some interval. That is, you are given the end points of the interval of interest. The average rate of change is the slope of a straight line between those end points. The slope formula applies:
[tex]m=\dfrac{y_2-y_1}{x_2-x_1} \quad\text{where the end points of the interval are $(x_1,y_1)$ and $(x_2,y_2)$}[/tex]

Answer:
[tex]y = 50x[/tex]
Step-by-step explanation:
Let's start off by trying to find the slope/gradient (commonly denoted as [tex]m[/tex]) of this function
[tex]m = \frac{\Delta y}{\Delta x}[/tex]
This means we divide the change in y over the change in x
Let's pick, for example, x = 3 (who's corresponding y is 150) and x = 4 (who's corresponding y is 200)
[tex]m = \frac{200 - 150}{4 - 3}\\\\m = 50[/tex]
Now we have this:
[tex]y = 50x+b[/tex]
Let's plug in a random value of x and y from this function in order to find b. I'll pick x = 2:
[tex]100 = 50\cdot 2 + b\\100 = 100 + b\\b = 0[/tex]
Since b is 0, we don't have to write it on our equation, meaning that our final equation is just
[tex]y = 50x[/tex]
To verify this, let's say we didn't know the value of y when x is equal to 4 and all we had was that equation:
[tex]y = 50\cdot 4\\y = 200[/tex]
Just like it is on the graph :)
Good luck!

HELP!!!!! part A: Ms.Donaldson earns $18.80 per hour for the first 40 hours she works in a week. She earns 1 1/2 times that amount per hour for each out beyond 40 hours in a week. Last week Ms.Donaldson worked 45.5 hours. How much money did she earn? Part B: A health incurrence payment of 34.55 was deducted from Ms.Donaldson's earnings for the week. After the incurrence deduction, payroll taxes equal to 28% of the balance were deducted. What was the amount that Ms.Donaldson received afterwards?
Answer: A. $907.10
B. $628.236
Step-by-step explanation:
For the first 40 hours, Ms.Donaldson will earn: = 40 × $18.80 = $752.0
We are informed that Ms.Donaldson worked 45.5 hours, this means that she worked an extra 5.5 hours. The amount paid for the extra hour will be:
= 5.5 × 1.5 × 18.8
= $155.10
The amount she earned will be:
= $752.0 + $155.10
= $907.10
B. A health incurrence payment of $34.55 was deducted from Ms.Donaldson's earnings for the week. Therefore, the amount she will have after the deduction will be:
= $907.10 - $34.55
= $872.55
After the incurrence deduction, payroll taxes equal to 28% of the balance were deducted. What was the amount that Ms.Donaldson received afterwards?
This will be:
= $872.55 - (28% × $872.55)
= $872.55 - (0.28 × $872.55)
= $872.55 - $244.314
= $628.236
A taxi company charges an initial fee of $1.95, plus $1.60 per mile driven. Shelly has $22.00 to spend on a taxi ride. Which inequality represents the number of miles, m, that Shelly can ride in a taxi
Answer:
Equation
1.95+1.6m ≤ 22
If solved
m ≤ 12.53
Step-by-step explanation:
SO we know the initial fee is 1.95
and for every mile driven, its $1.6
And we know that Shelly can spend less then or exactly the price of 22.
We know that m is miles driven
So we can make an equation
1.95+1.6m ≤ 22
1.95 can’t change since initial fee
1.6*m becuase its 1.6 for every mile driven and since “m” miles were driven, we multiply that by 1.6
Now it can’t go over 22 but it could be less than 22.
So this equation makes sense
If we solve it, it would be about m ≤ 12.53 miles
Bridget purchased 3 pairs of shoes online. The total bill of $126.81 included a $7.50 shipping charge and 6% tax on the total purchase. If the shoes that Bridget purchased were all priced the same, how much did each pair of shoes cost
Answer:
$37.
Step-by-step explanation:
Firstly, let's set the price of each pair of shoe to be x.
Since each pair of shoes costs the same, and there are three pairs, we can set the original price to be 3x.
Now, to apply the shipping charge, all we have to do is add 7.50 to 3x, getting 3x + 7.5.
Next, to apply a 6% tax, we can multiple the whole expression by (100% + 6%), getting (3x + 7.5) [tex]\cdot[/tex] 106%.
Since the whole bill foots to a total of $126.81, we can set the final equation to be:
[tex](3x + 7.5) \cdot 106\% = $126.81[/tex]
[tex](3x + 7.5) \cdot \frac{106}{100} = $126.81[/tex]
[tex]3x + 7.5 = $126.81 \cdot \frac {50}{53}[/tex]
[tex]3x = $119.6 - 7.5[/tex]
[tex]3x = 112.1[/tex]
[tex]x \approx \$37[/tex]
Hope this helped!

Harloe’s cats love Christmas songs. Every day she sings “Jingle Bells” five times, “Silver Bells” twice as many times as “Jingle Bells” and “Silent Night” once before bedtime.
A. How many songs does Harloe sing each day?
B. How many songs does Harloe sing in the weekend?
Answer:
A- 16 songs a day
B- 32 songs in the weekend
Step-by-step explanation:
A- if she songs "jingle bells" 5 times, the sings"silver bells" twice as many times, that would just be like multiplying 5 x 2, which equals 10, then add the 5 times she sings jingle bells, that would be 15. then she sings "silent night" one time which adds on to the other songs to get 16 songs a day
B- the weekend has 2 days in it so you would just multiply 16 x 2 which gives you 32
If the measurment of the angles of a triangle are 3b,2b,and 4b then what is the smallest angle
Given:
The measurement of the angles of a triangle are 3b,2b,and 4b.
To find:
The smallest angle.
Solution:
According to the angle sum property, the sum of all angles of a triangle is 180 degrees.
[tex]3b+2b+4b=180^{\circ}[/tex] [Angle sum property]
[tex]9b=180^{\circ}[/tex]
Divide both sides by 9.
[tex]b=20^{\circ}[/tex]
Now,
[tex]3b=3(20^{\circ})=60^{\circ}[/tex]
[tex]2b=2(20^{\circ})=40^{\circ}[/tex]
[tex]3b=4(20^{\circ})=80^{\circ}[/tex]
Therefore, the smallest angle is 40 degrees.
