First you have to find the surface area of what he is painting
Finding the areas of all the rectangles he is painting
14 * 8 = 112
14 * 8 = 112
12 * 8 = 96
12 * 8 = 96
12 * 14 = 168
Add all these up
112 + 112 + 96 + 96 + 168 = 584
Divide this by the amount of area a pint of paint covers
584 / 90 = 6.4888...
He needs 7 pints of paint because he needs more than 6
Multiply this by the cost of 1 pint of pint
7 * 7.98 = 55.86
The answer is $55.86
Hope this helps!
A = (8 ft)(14 ft) +(8 ft)(12 ft) +(8 ft)(14 ft) +(8 ft)(12 ft) +(14 ft)(12 ft)
A = (8 ft)*2*(14 ft +12 ft) +(14 ft)(12 ft) . . . . rearranging to simplify a bit
A = 2*(8 ft)(26 ft) +(14 ft)(12 ft)
A = 416 ft² +168 ft²
A = 584 ft²
6 pints of paint will cover 6*(90 ft²) = 540 ft², not quite enough. The next higher multiple of 90 ft² is 7*(90 ft²) = 630 ft², more than adequate.
Jake will need to purchase 7 pints of paint.
The cost of Jake's purchase will be 7*$7.98 = $55.86.

amelia and 2 of her friends went out to lunch. each girl ordered exactly the same meal. the total cost 55.08, which included 8% sales tax. what was the price of each meal, not including tax?
Answers
108% = 55.08
1% = 55.08 ÷ 108 = $0.51
100% = $51
3 meals = $51
1 meal = $51 ÷ 3 = $17
Answer: $17
Answer:
$16.8912
Step-by-step explanation:
We are given that Amelia and her two friends went out to lunch.
If each girl ordered exactly the same meal.
We have to find out the value of price of each meal without tax.
Total cost of meals=$55.08
Cost of 3 meals with tax=$55.08
Sales tax=8% of $55.08
8% of 55.08=[tex]\frac{8}{100}\times55.08[/tex]
8% of 55.08= $4.4064
Cost of 3 meals without tax=$55.08-$4.4064=$50.6736
Cost of each meal=[tex]\frac{50.6736}{3}=[/tex]$16.8912
Hence, the cost of each meal without tax=$16.8912
A jogger goes 1.5km west and then turns south.If the jogger finishes 1.7 km from the starting point,how far south did the jogger go?
Answers
You can use the Pythagorean Theorem to solve this
[tex] a^{2} + b^{2} = c^{2} [/tex]
c is the hypotenuse
a and b are the legs
Put in the values you know
[tex] 1.5^{2} + b^{2} = 1.7^{2} [/tex]
Square the numbers
[tex]2.25+ b^{2} =2.89[/tex]
Subtract 2.25 from both sides
[tex] b^{2} =0.64[/tex]
Take the square root of both sides
b = 0.8
The answer is 0.8km
Hope this helps!
Final answer:
To find out how far south the jogger went, we use the Pythagorean theorem. Given the distances of 1.5 km west and 1.7 km from the start, the jogger went 0.8 km south.
Explanation:
To determine how far south the jogger went, we can use the Pythagorean theorem, as the jogger's path forms a right-angled triangle where one leg of the triangle is the distance west, the other leg is the distance south, and the hypotenuse is the distance from the starting point.
The question states the jogger goes 1.5 km west and ends up 1.7 km from the starting point. We denote the distance travelled south as y. According to the Pythagorean theorem:
west^2 + south^2 = distance from start^2
y = √0.64
y = 0.8 km
So the jogger went 0.8 km south.

Hope this helps :)
area = 22.5 ft²
Explanation:
The total area can be calculated by summing the areas of the rectangle and the triangle.
1- getting the area of the rectangle:
area of square = length * width
In the given, we have:
length = 4 ft
width = 5 ft
Therefore:
area of rectangle = 4 * 5 = 20 ft²
2- getting the area of the triangle:
area of triangle = 0.5 * base * height
In the given, we have:
base = 5 ft
height = 1 ft
Therefore:
area of triangle = 0.5 * 5 * 1 = 2.5 ft²
3- getting the total area:
Total area = area of rectangle + area of triangle
Total area = 20 + 2.5 = 22.5 ft²
Hope this helps :)

we know that

CR=CS-----> is the radius of the circle
CR and AB are perpendicular
the triangle SCR is a isosceles triangle
angle SCR is equal to 80°------> is a central angle
angle CSR and angle CRS are equal to 50°----> because 80+50+50=180
therefore
m∠SRA=90°-m∠CRS------> m∠SRA=90°-50°=40°
the answer is
m∠SRA=40°

What is a fraction?Fractions represent the parts of a whole or collection of objects.
A fraction has two parts. The number on the top of the line is called the numerator and the number on the top of the line is called the denominator.
Now it is given that,
Pounds of glass recycled = 7 2/3
⇒ Pounds of glass recycled = 23/3
Pounds of paper recycled = 9 3/4
⇒ Pounds of paper recycled = 39/4
Thus, total pounds of glass and paper recycled = Pounds of glass recycled + Pounds of paper recycled
⇒ total pounds of glass and paper recycled = 23/3 + 39/4
⇒ total pounds of glass and paper recycled = 209/12
⇒ total pounds of glass and paper recycled = 17 5/12 pounds
Thus, the students recycle 17 5/12 pounds of glass and paper all together.

Two functions are represented in different ways. Function 1: y = 32x + 45 Function 2: x y 0 65 1 85 2 105 3 125 Which statements are true? Select each correct answer. Function 1 has a greater rate of change than function 2. Function 2 has a greater rate of change than function 1. Function 1 has a greater y-intercept than function 2. Function 2 has a greater y-intercept than function 1.
Answers
rate of change = 32
y-intercept = 45 when x = 0
Function 2: x y 0 65 1 85 2 105 3 125
rate of change = (85-65)/(1-0) = 20
y-intercept = 65 when x = 0
So the following statements are correct:
Function 1 has a greater rate of change than function 2.
Function 2 has a greater y-intercept than function 1.
Answer:
Step-by-step explanation:
Function 1: y = 32x + 45 <- 45 is y-intercept
Function 2: x y 0 65 <- 65 is y-intercept
So Function 2 has a greater y-intercept than function 1.
Function 1: y = 32x + ... <- 32 is rate of change
Function 2: x y 0 65 1 85
rate of change = 85 - 65 = 20
So Function 1 has a greater rate of change than function 2.
