Jena's income is $3800 a month, and she plans to budget 13 of her income for savings and 16 of her income for groceries.
What fraction of her income does she plan to spend each month on these two items together?
The fraction of Jena's income does she plan to spend each month on these two items together is 1/2
The fraction of her income does she plan to spend each month on the two itemsJena's income for the month = $3800Fraction of Jena's income for savings = 1/3Fraction of Jena's income for groceries = 1/6Amount of Jena's income spent on savings = 1/3 × $3800
= 1266.666666666666
Approximately,
= $1,266.67
Amount of Jena's income spent on groceries = 1/6 × $3800
= 633.3333333333333
Approximately,
= $633.33
Amount spent on the two items = $1,266.67 + $633.33
= $1900
Fraction of Jena's income spent on the two items = 1/3 + 1/6
= (2+1) / 6
= 3/6
= 1/2
So therefore, Jena spent 1/2 of her income on savings and groceries.

Please help me with this, show full work for all questions, thank you!Question 3
Answer:
0.375
Explanation:
The probability of red and purple can be calculated as the frequency for rean and purple over the total frequency
Red has a frequency of 4
Orange has a frequency of 1
Yellow has a frequency of 1
Green has a frequency of 7
Blue has a frequency of 1
Purple has a frequency of 2
The total frequency is
4 + 1 + 1 + 7 + 1 + 2 = 16
And the frequency for red and purple is
4 + 2 = 6
Then, the probability is equal to
P = 6/16 = 0.375
So, the answer for question 3 is 0.375

The average rate of change of the function is found as 1.
What is termed as the rate of change of function?The rate of change function has been described as the rate during which one quantity changes in relation to another. The rate of change from y coordinates to x coordinates can be calculated as Δy/ Δx = (y2 - y1)/ (x2 - x1 ).For the given question;
The function is given by the equation;
g(x) = -x² - 9x + 27
The interval of the function lies as;
-9 ≤ x ≤ -1.
Let,
a = -1 ans b = -9
Then,
g(a) = g(-1), Put x = -1 in the function.
g(-1) = -(-1)² - 9(-1) + 27
g(-1) = 35
Now, g(b) = g(-9), Put x = -9 in the function.
g(-9) = -(-9)² - 9(-9) + 27
g(-9) = 27
Thus, the average rate of change of the function is-
Average rate of change = [g(a) - g(b)]/[a - b]
= [35 - 27]/[-1 + 9]
= 8/8
= 1
Thus, the average rate of change of the function is found as 1.

Congruent is what?When two figures or objects in geometry have the same shapes, sizes, or are mirror images of one another, they are said to be congruent.
Formally, two sets of points are said to be congruent if, and only if, an isometry, which is a collection of rigid motions including translation, rotation, and reflection, can transform them into one another.
This shows that resizing an object will not allow it to be properly aligned with another object, only by moving and reflecting it. Therefore, two independent plane figures on a piece of paper are congruent if we can cut them out and then precisely line them up. The paper might be distributed.
Each box is the same size in terms of length and width. The only change is where the figure is located.
Transformations can be divided into four categories: translation, rotation, reflection, and dilation.
Two figures are said to be "congruent" if they can be positioned perfectly over one another. Congruent refers to things that are exactly the same size and shape.
Hence, A and B are congruent.

What is Surface area?A solid object's surface area can be stated as a measurement of the overall space that the object's surface takes up. As an alternate, surface area can also be described as the area of the entire outer part, or which is said as the uppermost layer of any kind of 3D object.
Square units are used in the calculation. The total area of all the outside surfaces makes up the surface area of a three-dimensional object, which is also expressed in square units.
As an example, we can take that in order to find the exact surface area of a cuboid, we have to add the areas of all 6 faces.
In this figure, we can see that it can be stated as a cylinder.
So, as we know the formula of the surface area of a cylinder can be written as:
2[tex]\pi[/tex]rh + 2[tex]\pi r^2[/tex]
Here r = 8/2
=4 mi
h = 2 mi
Thus, putting the values, we have,
Surface area = [2 x 3.14 x 4 x 2] + [2 x 3.14 x 4 x 4]
= 50.24 + 100.48

What’s the slope I need help
Answer:
-8/3
Step-by-step explanation:
You want the slope of the line shown in the graph.
Slope from point coordinatesWhether counting grid squares on the graph, or using the slope formula, it is convenient to choose two points on the grid where the line crosses the intersection of grid lines.
It appears, the line passes through grid points (1, 4) and (4, -4). Using the slope formula, we find the slope of the line to be ...
m = (y2 -y1)/(x2 -x1)
m = (-4 -4)/(4 -1) = -8/3
The slope of the line is -8/3.
Counting grid squaresThe slope is the ratio of "rise" to "run" for the line. From the two points we see where the line crosses grid intersections, we have a "rise" of -1 from y=4 to y=-4, and a "run" of 3 from x=1 to x=4.
rise/run = -8/3 = slope of the line

The balance Ranjan will receive from the cashier is ₹ 0
How to determine the balanceBased on the information given, we have that;
shirt costs ₹(a² –ab -b² ) pair of trousers cost ₹(2a² +8ab-2b² ) pair of shoes cost ₹(a² –3ab + 4b² ) Ranjan paid ₹(2a+b )2Now, expand the bracket for the payment, we have;

Add like terms
4a² + 4ab + b²
Now, let's add the amount for the items bought
a² –ab -b² + 2a² +8ab-2b² + a² –3ab + 4b²

A circle has a center at (4, -7) and a radius of 4 units. What is the equation of this circle?
O (4)² + (y + 7)² = 16
O (x + 4)² + (y + 7)² = 4²
O(x-4)² + (y - 7)² = 16
O(x + 4)² + (y - 7)² = 4²
the equation for the circle with radius, r = 4 units and center =(4,-7)
will be (x-4)² + (y+7)² = (4)².
When the center and radius of a circle are known, how do you determine its equation?
Use the formula (x-a) ² + (y-b) ² = r ² to determine a circle's equation when you are aware of its radius and center. Here, stands for the circle's center, and is its radius. This equation is essentially a variant way of writing the general equation for a circle.
In this question,
we are given the center of our circle to be,
(4,-7) ≈ (a,b)
thus we are given,
a = 4
