The equation representing the amount spend on salad and pizza is E = 5S + 2P , P in terms of E and S is P = (1/2)(E - 5S) and the completion of table is given by:
Budget Bowls of salad Slice of pizza
$40.00 0 20
$40.00 4 10
$40.00 8 0
Let 'E' represents the dollars spends on salad and pizza.
'S' represents the bowls of salad, 'P' represents the slice of pizza
Cost of bowl of salad = $5.00
Cost of slice of pizza = $2.00
Equation represents dollars spends on salad and pizza is :
E = 5S + 2P
Equation representing P in terms of E and S is:
P = (1/2)(E - 5S)
If E = $40.00
Then to make equation true value of S and P for the table is:
E = $40.00
S = 0
40 = 5(0) + 2P
⇒P = 20
E = $40.00
S = 4
40.00 = 5(4) + 2P
⇒P = 10
E = $40.00
P = 0
40.00 = 5S + 2(0)
⇒S = 8
In table form:
Budget Bowls of salad Slice of pizza
$40.00 0 20
$40.00 4 10
$40.00 8 0
Therefore, the equation representing total amount of money spend is
E = 5S + 2P , representation of P in terms of E and S is P = (1/2)(E - 5S) and complete table is equal to :

the retail price of a tv is $600. The discount is 25% and tax is7%. how much do you pay for the tv?
Answer:
$ 481.50
Step-by-step explanation:
Discount:
Discount = 25% of retail price of TV
= 0.25 * 600
= $ 150
Price after discount = Retail price - discount
= 600 - 150
= $ 450
Tax:
Tax = 7% of 450
= 0.07 * 450
= $ 31.50
Amount to be paid:
Amount needs to be paid = price after discount + tax
= 450 + 31.50
= $ 481.50

A population, f(x), after x years may be modeled with f(x)=2(3)^x. What is the initial amount , growth rate, domains and range?
2 is the initial amount, growth rate is (3ˣ - 1) × 100% , domain of the function is all real numbers and range of the function is all positive real numbers
What is a function?A relation is a function if it has only One y-value for each x-value.
The given function is:
f(x) = 2(3)ˣ
To find the initial amount, we need to find f(0):
f(0) = 2(3)⁰ = 2(1) = 2
So the initial amount is 2.
To find the growth rate, we can use the formula:
growth rate = (f(x) - f(0)) / f(0) × 100%
= (2(3)ˣ - 2) / 2 × 100%
= (3ˣ - 1) × 100%
So the growth rate is (3ˣ - 1)×100%.
The domain of the function is all real numbers because the function is defined for all values of x.
The range of the function is all positive real numbers because the function is always positive for any value of x.
Specifically, the range of the function is (0, infinity).
Hence, 2 is the initial amount, growth rate is (3ˣ - 1) × 100% , domain of the function is all real numbers and range of the function is all positive real numbers

What is an equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
Example:
2x + 3 = 7 is an equation.
We have,
f(x) = -x² - 12x - 10
This is in the form of ax² + bx + c.
a = -1, b = -12, c = -10
The axis of symmetry is x = -b/2a
x = 12/(-2)
x = -6
Now,
f(x) = -x² - 12x - 10
f(x) = -(x² + 12x + 10)
f(x) = - { (x² + 12x + 36) - 36 + 10}
f(x) = -(x + 6)² + 26
This is in the form of f(x) = a (x - h)² + k
a = -1, h = -6, k = 26
Vertex = (h, k) = (-6, 26)
Now,
f(x) = -x² - 12x - 10
f'(x) = -2x - 12
f''(x) = -2
It is a negative value.
This means f(x) has a maximum value.

Q2: What is the perimeter of triangle ABC? Show all of your work for full credit.
The value of x in the triangle is 17 .
The perimeter of the triangle ABC is 86 units.
How to use triangle proportionality theorem to find side of a triangle?Triangle Proportionality Theorem states that If a line parallel to one side of a triangle intersects the other two sides, then it divides those sides proportionally.
Therefore, let's use the theorem to find the value of x in the triangle.
Hence,
20 / 4 = 2x - 4 / 6
cross multiply
120 = 4(2x - 4)
120 = 8x - 16
120 + 16 = 8x
136 = 8x
divide both sides by 8
x = 136 / 8
x = 17
Hence, let's find the perimeter of the triangle ABC.
perimeter of the triangle ABC = 24 + 26 + 2(17) - 4 + 6
perimeter of the triangle ABC = 50 + 30 + 6

According to a recent poll, 27% of Americans get 30 minutes of exercise at least five days each week. Let's assume this
is the parameter value for the population. If a simple random sample of size were taken, what is the approximate
probability that , the proportion who exercise at least five days per week, is higher than 0.30?
The probability that the proportion of a sample is higher than 0.30 can be estimated using the Central Limit Theorem (CLT) which states that the distribution of the sample means approaches a normal distribution as the sample size increases. With a large sample size (n >= 30), we can use the normal distribution to approximate the distribution of the sample means.
Assuming the sample size is large, the standard error (SE) of the sample mean is given by
SE = sqrt(p * (1 - p) / n), where p is the population proportion (0.27) and n is the sample size.
With this information, we can find the Z-score corresponding to 0.30 using the formula: Z = (0.30 - 0.27) / SE
Since we don't know the sample size, we'll assume a conservative sample size of 30.
With a sample size of 30, the SE is approximately 0.039, and the Z-score is approximately 0.77.
Using a standard normal table, we can find the probability of a Z-score being greater than 0.77 is approximately 0.22.
Therefore, the approximate probability that the proportion who exercise at least five days per week is higher than 0.30 is 0.22.

Tell whether the triangles are congruent. Explain your reasoning.
Answer:
Yes because there all the same shape the size dosent effect the shape of it.
Step-by-step explanation:
Answer:
101. ΔABC congruent to ΔDEF
102. ΔJKL not congruent to ΔMNO
Step-by-step explanation:
Q 101
Triangle ABC has 3 sides equal to each of the three sides of DEF
The corresponding two angles of ABC and DEF are also equal
So the third angle of ABC ∠B must be equal to the third angle of DEF so we have three sides equal, three angles equal, hence congruent
ΔABC congruent to ΔDEF
Q 102
We have JL = MP = 1.9
m∠J = m∠M = 24°
The other two angles are not correspondingly equal
This only makes one side equal and one angle equal. Not sufficient to make it congruent
Hence ΔJKL not congruent to ΔMNO
If A(0, 4), B(5, y), and AB = 13. What is y?
The required value of y for the given segment AB is given as y = 16, -8.
A line is a straight curve connecting two points or more showing the shortest distance between the initial and final points.
here,
A(0, 4), B(5, y), and AB = 13.
Applying the distance formula,
D = √[[x₂ - x₁]² + [y₂- y₁]²]
Substitue the value in the above expression,
13 = √[[5 - 0]² + [y - 4]²]
169 = 25 + [y - 4]²
[y - 4]² = 144
y - 4 = ± 12

katie rents a car while spending her vacation travelling in australia. when she returns the car, she has driven 1400 miles and used about 56 gallons of gas. if gas costs an average of $5.099 per gallon, estimate how much she spent on fuel.
Katie spent approximately $285.544 on fuel during her vacation in Australia.
The Average Cost is the per unit cost of the product received by dividing the total cost (TC) by the total output (Q). By per unit cost of production, we mean that all the fixed and variable costs are considered for calculating the average cost. Thus, it is also called Per Unit Total Cost.
Symbolically, the average cost is expressed as:
AC = TC/Q
To estimate how much Katie spent on fuel, you need to multiply the number of gallons of gas she used (56 gallons) by the average cost of gas per gallon ($5.099):
56 gallons × $5.099/gallon = $285.544
So, Katie spent approximately $285.544 on fuel during her vacation in Australia.

P(X + Y < 4) = 0.53 rounded to the first decimal place.
To find the probability P(X + Y < 4),

X + Y < 4, and then sum up the corresponding probabilities in the table.
We can start by plotting the points (x1, x2) on a graph and finding the region where X + Y < 4.
This region can be determined by shading in the portion of the graph that is below the line X + Y = 4.
Next, we need to find the values of x1 and x2 in the table that fall within this region and sum up their probabilities.
