Carmen can buy 4 tubes of paint at $4.80 each after purchasing 2 paint brushes at $6.70 each from her $35 winnings.
Carmen won a prize of $35 in a contest. To answer how many tubes of her favorite paint brand she can buy, first, we need to deduct the cost of the two paint brushes she needs, which are $6.70 each. The total cost for two brushes is:
2 brushes x $6.70 per brush = $13.40
Subtracting this amount from her winnings:
$35.00 - $13.40 = $21.60 remaining
Now, we divide the remaining money by the cost of each tube of paint, which is $4.80, to find out how many tubes she can purchase:
$21.60 / $4.80 per tube = 4.5 tubes
Since Carmen cannot buy half a tube, she can buy 4 tubes of paint and will have some money remaining.

Step-by-step explanation:
We can use the Exterior Angle of a Triangle theorem to find x. It states that the exterior angle of a triangle is equal to the sum of the two opposite interior angles.
We will start with x+5. It is equal to 79 +____ an angle we don't know yet. But we do know that the angle____ and x equals 180 because they form a straight line. Therefore the unknown angle must be 180-x.
So we will set x+5=79+180-x. We will combine like terms, use inverse operations, and isolate.
x+5=79+180-x
x+5=259-x
x+x+5=259-x+x
2x+5=259
2x+5-5=259-5
2x=254
x=127

A triangular table top has a base that is twice as long as its height. If the area of the table surface is 324 square inches, what is the value of the height and the base?
Answer:
Height is 18 inches.
Base is 36 inches.
Step-by-step explanation:
Let the base of the triangular table top be x inches.
The height will be [tex]\frac{1}{2}[/tex]x inches.
The area of the triangular table top is 324 inches²
Area of a triangle = [tex]\frac{1}{2}[/tex] × Base × Height
342 inches² = [tex]\frac{1}{2}[/tex] × x × [tex]\frac{1}{2}[/tex]x
[tex]\frac{x^2}{4}[/tex] = 324
Finding the square root on both sides gives;
[tex]\frac{x}{2}[/tex] = 18
Therefore x (the base) = 36 inches
And [tex]\frac{1}{2}[/tex] (the height) = 18 inches.
Final answer:
The height of the triangular table top is 18 inches, and the base is 36 inches, using the formula for the area of a triangle and given that the base is twice the height with an area of 324 square inches.
Explanation:
The question requires finding the height and base of a triangular table top given that the area is 324 square inches and the base is twice as long as the height. To find these dimensions, we can use the formula for the area of a triangle, which is Area (A) = [tex]\frac{1}{2}[/tex] × base (b) × height (h). Given that the base is twice the height, we can express the base as 2h.
Now, we can set up the equation using the given area: 324 = [tex]\frac{1}{2}[/tex] × 2h × h. Simplifying gives us 324 = h², so the height (h) would be the square root of 324, which is 18 inches. The base (2h) is therefore 36 inches. So, the dimensions of the tabletop are a base of 36 inches and a height of 18 inches.
At the county fair, two hot dogs and an ice cream cone cost $2.50. Two slices of pizza and an ice cream cone cost $3.50. What is the total cost of one hot dog, one slice of pizza and one ice cream cone at the county fair?
Answer:
The total cost of one hot dog, one slice of pizza and one ice cream cone at the county fair is $3.
Step-by-step explanation:
Let us assume that the cost of the one hot dogs be x.
Let us assume that the cost of the one ice cream cone be y.
Let us assume that the cost of the one silce of pizza be z.
As given
At the county fair, two hot dogs and an ice cream cone cost $2.50.
Than the equation becomes
2x + y = 2.50
Two slices of pizza and an ice cream cone cost $3.50.
2z + y = 3.50
Than two equations are
2x + y = 2.50 and 2z + y = 3.50
Adding the both above equation.
2x + y + 2z + y = 2.50 + 3.50
2x + 2z + 2y = 6
[tex]x + y + z = \frac{6}{2}[/tex]
x + y + z = 3
Therefore the total cost of one hot dog, one slice of pizza and one ice cream cone at the county fair is $3.

basketball goal 10 ft high casts a shadow 36 ft long. Find the elevation to the sun
Answer:
angle of elevation to the sun is 15.52°
Step-by-step explanation:
basketball goal 10 ft high casts a shadow 36 ft long
This forms a right angle triangle. the diagram is attached below
We need to find out angle A
We know opposite side = 10ft and adjacent side = 36 ft
We use tan formula
[tex]tan(A) = \frac{opposite}{adjacent}[/tex]
[tex]tan(A) = \frac{10}{36}[/tex]
To find A we move tan to the other side, it becomes tan^-1
[tex]A =tan^{-1}(\frac{10}{36})[/tex]
A = 15.52
So angle of elevation to the sun is 15.52°

Your class field trip is to a museum that charges $4 for adults and $2 for students. If cost $60 for 27 tickets for your class, the teacher, and chaperones. How many adult tickets were purchased? How many student tickets were purchased?
Answer:
3 adults and 24 students
Step-by-step explanation:
We can set-up a system of equations to find the number of adults. We know students and adults attended. We will let s be the number of students and a be the number of adults. Since 27 tickets were purchased, then s+a=27.
We also know they were purchased for $60 and adult tickets cost $4 and student tickets cost $2. We can write 2s+4a=60.
We will solve by substituting one equation into the other. We start by solving the first equation for c. s+a=27 becomes s=27-a.
Now we substitute s=27-a into 2s+4a=60. Simplify and isolate the variable a.
2s+4a=60
2(27-a)+4a=60
54-2a+4a=60
54+2a=60
54-54+2a=60-54
2a=6
a=3
This means that 3 adults attended and 24 students attended since 3+24=27.

There are more inches on a football field (100 yards) than there are centimeters on a 28 meter basketball court true or false
Answer:
The given statement is True
Step-by-step explanation:
WE have to find out that which one has more no of inches
so now we have
100 yards football field
28 meter basketball court
Total no of inches in one yard = 36 inches
Total no of inches in 100 yard = 36 * 100
= 3600 inches
Now total no of inches in one meter = 39.3701 inches
Total no of inches in 28 meter = 28 * 39.3701
=1102.3628 inches
So we can see that 1102.3628 is smaller than 3600
So It can also be seen that football field has more inches then a basketball court
So the given statement is True
Answer:
The given statement is true.
Step-by-step explanation:
First we will apply conversions to given terms:
1 yard has = 36 inches
So, 100 yards has = [tex]36\times100=3600[/tex] inches.
1 meter = 100 cm
So, 28 meters has = [tex]28\times100=2800[/tex] cm
So, now upon comparing we can see that 3600 is greater than 2800.
Therefore, the inches in a 100 yard field are greater than the cm in a 28 meter basketball court.
The statement given here is true.

A cell phone package charges $39 even if 0 minutes are used during the month. Each additional minute of talk time adds $0.07. What is the total cost if you talked on the phone for 10 hours during the month?
using the formal y = mx + b
Answer:
total cost = $ 81
Step-by-step explanation:
It is given that the fixed cost is $ 39
and the cost per minute is $0.07
Let us assume the number of minutes used be x
we have
total cost = cost per minute × number of minutes used + fixed cost
we plug the given values, so we have
[tex]total cost = 0.07 x+39[/tex]
we need to find the total cost for 10 hours used
x= 10 hours = 10(60) minutes = 600 minutes
so we have total cost for x= 600 minutes
[tex]total cost = 0.07(600)+39[/tex]
[tex]total cost =42+39 = 81[/tex]
hence the total cost = $ 81

Answer:
x-intercept = 3 ; y-intercept = -5
Step-by-step explanation:
Lets rearrange the equation into the form y = mx + b:
5x - 3y = 15
-3y = 15 - 5x
Divide by -3:
y = 5x/3 - 5
Here we know that b (-5) is the y-intercept, and we can find the x-intercept by starting at the y-intercept and using the slope till we get the x-intercept. Or you can set y = 0 and solve for x, either way you get x-intercept = 3.
This equation is in standard form, if you put it into slope-intercept form, you will be able to graph it. Once you graph it you will be able to find the intercepts.
5x - 3y = 15
-3y = -5x + 15
y = 5/3x - 5
X-Intercept: (3,0)
Y-Intercept: (0, -5)

Define a function that transforms the parent root function with a horizontal compression by a factor of 5 and a downward shift of 10 units.
Answer:
[tex]f(x)=\sqrt[n]{5x}-10[/tex]
Step-by-step explanation:
Compression of a function (in graph) occurs when the coefficient of the function (the number in front of [tex]x[/tex]) increases from 1. e.g. 2, 3, 4, 5 etc.Expansion is when this same value is a fraction, e.g. [tex]\frac{1}{3} ,\frac{1}{5}[/tex] etc.Vertical shift upwards is when there is a positive number added to the original function and vertical shift downwards is when there is a negative number added to the original function.Parent root function is given by:
[tex]f(x)=\sqrt[n]{x}[/tex]
According to rules,
Compression would be achieved by multiplying the [tex]x[/tex] by 5. So, we would have [tex]\sqrt[n]{5x}[/tex]Downward vertical shift would be achieved by adding a [tex]-10[/tex] to the function.So, [tex]\sqrt[n]{x}-10[/tex]Combining these 2 transformation gives us the function:

c. even likely degree 4
Step-by-step explanation:
A polynomial graph has several features we look for to determine the equations.
The zeros of the function are the x-intercepts. If the x-intercepts touch but do not cross then the intercepts have an even multiplicity like 2, 4, 6, etc. If the x-intercepts cross over then they have an odd multiplicity. Degree is the exponent or multiplicity of each zero. Therefore if we know the multiplicity of each zero we can add them together to find or make an educated guess for the degree of the entire polynomial. The shape of the graph tells us what type of polynomial. Odd degrees have a backwards S shape. Even degrees have a W shape. The shape can even tell us the if the equation has a positive or negative leading coefficient. Upside down W or an M shape is negative. While a sideways S shape is negative.In this graph, there are four real zeros: -2,-1,1,2
We can write them in intercept or factored form as (x-2), (x-1), (x+1) and (x+2).
Because the graph crosses the x-axis at -2, it's multiplicity is odd likely 1. This is the same for each of the zeros or x-intercepts.
The graph a W shape and facing upwards so it has a positive leading coefficient with an even degree.
This means the function has a degree of 4 or higher with the degree being even.

The sum does not converge because [tex]\dfrac76>1[/tex].
Answer:
It does not converge.
Step-by-step explanation:
Given is an infinite geometric series whose first term is a = 4/7 and common ratio is r = 7/6.
The series ∑a·rⁿ converges if we have |r| < 1.
And the series ∑a·rⁿ diverges if we have |r| > 1.
But we can easily check that |r| = 7/6 > 1.
It means the given series diverges, i.e. does not converge.
Hence, option D is correct answer, i.e. It does not converge.

'' HOT PIZZA''is offering 20% disscount on all its pizzas. Ali orders a pizza for the reduced price of ?5.60 what was the origanal pizza?
Final answer:
To find the original price of a pizza before a 20% discount that resulted in a final price of £5.60, divide the final price by 0.8. The original price is calculated to be £7.00.
Explanation:
The question involves determining the original price of a pizza before a 20% discount was applied, given that the reduced price after the discount is £5.60.
To calculate the original price, we can use the formula for finding the original price when the final price and discount rate are known.
Let's denote the original price as OP. Since a 20% discount was applied, the pizza sold for 80% of its original price. The equation representing this situation is:
0.8 × OP = £5.60
Now, we divide the reduced price by 0.8 to find the original price:
OP = £5.60 / 0.8
OP = £7.00
Thus, the original price of the pizza was £7.00 before the 20% discount was applied.

Step-by-step explanation:An exponent represents repeated multiplication. For example, ...
... x^3 = x·x·x
... x^2 = x·x
If we divide these, the x's in the denominator cancel an equal number in the numerator:
... (x·x·x)/(x·x) = x
If we represent the repeated multiplication using exponents, we can represent the cancellation by subtraction:
... (x^3)/(x^2) = x^(3-2) = x^1 = x
Once we have this idea in mind that division can be done by subtracting denominator exponents, we can use it regardless of the magnitude or sign of the exponents involved.
