I'm struggling a little bit can someone help?? A cell phone costs $850. You have a coupon for 15% off. How much will you pay for the phone? Include 13% tax
Answer:
722.50
Step-by-step explanation:
not exactly sure its right but i did use a calculator so I'm pretty sure it's right
Given:
850 dollars is the original price of the cell phone. (discount) coupon for 15% offtax is 13 percent.------------------------------------------------------------------
original price - discount = sales price
850 - (850 x [tex]\frac{15}{100}[/tex] ) = sales priceANSWER: $722.50 or [tex]\frac{1445}{2}[/tex]Include 13% tax... price + sales tax = total price of the phone
722.50 + (722.50 x [tex]\frac{13}{100}[/tex] ) = ?ANSWER: The final price of the cellphone is $816.43
Nick works two jobs to pay for college. He tutors for $15 per hour and also works as a
bag boy for $8 per hour. Due to his class and study schedule, Nick is only able to work
up to 20 hours per week but must earn at least $150 per week. If t represents the
number of hours Nick tutors and b represents the number of hours he works as a bag
boy, which system of inequalities represents this scenario?
A. t+b = 20
15t + 8b < 150
B. t+b 20
15t + 8b = 150
C. None of the systems shown represent this scenario.
D. t+b = 20
15t + 8b > 150
Answer:The answer is B.
He can't work more than 20 hours so t+b must be less than or equal to 20.
He has to earn $150 so it cannot be less than 150. Theoretically he could earn more, e.g doing 10 hours of each job which equals $230
Therefore t + b less than or equal to 20 15t + 8b greater than or equal to 150

Jessica estimated that her family used 30% more water this month compared to last month . they used 12000 gallons of water last month , how much water did they use this month
Answer:
15,600 Gallons
Step-by-step explanation:
The 30% of 12000 is 3600 thus, Jessica's family used 15600 gallons of water.
What is the percentage?The percentage is defined as a given amount in every hundred. It is a fraction with 100 as the denominator percentage is represented by the one symbol %.
The percentage is also called the indicating hundredths. Thus, 2% is two-hundredth, which means 2%=2/100=0.02.
As per the given,
Last used of water = 12000
30% of 12000 = (30/100)12000 = 3600
Water used in the current year = 12000 + 3600 = 15600 gallons.
Hence "The 30% of 12000 is 3600 thus, Jessica's family used 15600 gallons of water".

Find the area of the trapezoid by decomposing it into other shapes
Answer:
60 cm ( squared )
Step-by-step explanation:
you can find the area of the trapezoid ( by decomposing it into other shapes ) by separating two triangles, and using the formula to find the area of triangles, which is A= 1/2 ( b x h ) and add the answer to those together ( 16 cm squared and 4 cm squared ), and after that, you can find the area to the rectangle by multiplying the l x w, which is 10 x 4 ( after separating the triangles.). That equals 40, and when you add them all together ( 16 + 4 + 40 ) it equals 60 cm (squared).

Standard to Slope Intercept Form
Put the following equation of a line into slope-intercept form, simplifying all fractions.
2x+8y=24
Answer:
y = - [tex]\frac{1}{4}[/tex] x + 3
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c
Given
2x + 8y = 24 ( subtract 2x from both sides )
8y = - 2x + 24 ( divide all terms by 8 )
y = - [tex]\frac{1}{4}[/tex] x + 3 ← in slope- intercept form

A restaurant makes pizzas with 6-inch diameters ad 12-inch diameters. Which of the following statement is true?
The area of the 12-inch pizza is twice the area of the 6- inch pizza
The area of the 12-inch pizza is three times the area of the 6-inch pizza
the area of the 6-inch pizza is 1/4 the area of the 12-inch pizza
the area of the 6-inch pizza is 1/6 the area of the 12-inch pizza
Answer:
The correct option is c: the area of the 6-inch pizza is 1/4 the area of the 12-inch pizza.
Step-by-step explanation:
The area (A) of each pizza is given by:
[tex] A = \pi r^{2} [/tex]
Where:
r: is the radius
For the 12-inch pizza we have:
[tex] A_{12} = \pi (\frac{12 inch}{2})^{2} = 113.1 inch [/tex]
And for the 6-inch pizza we have:
[tex] A_{6} = \pi (\frac{6 inch}{2})^{2} = 28.3 inch [/tex]
The ratio between A₆ and A₁₂ is:
[tex] \frac{A_{6}}{A_{12}} = \frac{28.3 inch}{113.1 inch} = 0.25 = \frac{1}{4} [/tex]
Hence:
[tex] A_{6} = \frac{A_{12}}{4} [/tex]
Therefore, the correct option is c: the area of the 6-inch pizza is 1/4 the area of the 12-inch pizza.
I hope it helps you!
The area of the 6-inch pizza is 1/4 the area of the 12-inch pizza
Given that;Diameter of pizza A = 12 inch
Diameter of pizza B = 6 inch
Computation:Ration of Area of Pizza A to B = [πr1²] / [πr2²]
Ration of Area of Pizza A to B = [(12/2)²] / [(6/2)²]
Ration of Area of Pizza A to B = [(6)²] / [(3)²]
Ration of Area of Pizza A to B = 36 / 9
Ration of Area of Pizza A to B = 4:1
So,
Option "C" is the correct answer of the following question.

Find the missing value to the nearest hundredth cos=4/38
Answer:
83.96 (approximately)
Step-by-step explanation:
I am not completely sure what the problem is asking, just like the last one, but I believe that you are just supposed to take the inverse of cosine. So, in your calculator, make sure it is in degrees mode, then usually you have to click the 2nd key and then cosine. You use the inverse of cosine when two sides are given, but you are not given the angle.
It should look like:
[tex]cos^{-1}(\frac{4}{38})[/tex], which is approximately 83.96.
Hopefully this is right, if not, please let me know. Good luck.

In ∆ABC,
∠A = 60°∠B = 60°BC = 12 units∠BDC = 90°To Find :Area of ∆ABC = ?Solution :As, we have :
∠A = 60°∠B = 60°So, By angle sum property of triangle :
∠A + ∠B + ∠C = 180°
[tex] \tt : \implies 60\degree + 60\degree + \angle C = 180\degree[/tex]
[tex] \tt : \implies 120\degree + \angle C = 180\degree[/tex]
[tex] \tt : \implies \angle C = 180\degree - 120\degree[/tex]
[tex] \tt : \implies \angle C = 60\degree[/tex]
Now, we have :
∠A = 60°∠B = 60°∠C = 60°As, all angles are of same length, therefore it is a equilateral triangle.
We know that sides of equilateral triangle are equal.
[tex] \tt : \implies AB = BC = AC[/tex]
Now, we have BC = 12 units.
Hence, all sides are of 12 units.
Now, we know that area of equilateral triangle is :
[tex] \large \underline{\boxed{\bf{Area_{(equilateral \: triangle)} = \dfrac{\sqrt{3}}{4} side^{2}}}}[/tex]
[tex] \tt : \implies Area = \dfrac{\sqrt{3}}{4} \times (12 \: units)^{2}[/tex]
[tex] \tt : \implies Area = \dfrac{\sqrt{3}}{\cancel{4}} \times \cancel{144} \: units^{2}[/tex]
[tex] \tt : \implies Area = \sqrt{3} \times 36 \: units^{2}[/tex]
[tex] \tt : \implies Area = 36\sqrt{3} units^{2}[/tex]
So, Area of given triangle is 36√3 units².

Answer:
1/2
Step-by-step explanation:
There are 6 marbles that are either red or green out of 12 total marbles, so you have:
6/12 = 1/2
Answer:
1/2
Step-by-step explanation:
To find the probability, you need to put the number of what you want to know the probability of over the total. In this case, we want to know what the probability of red and green over the total is. So, hence the equation:
[tex]\frac{5+1}{12}[/tex] or [tex]\frac{6}{12}[/tex] which can be simplified to [tex]\frac{1}{2}[/tex].
