Answer:
A = 5.99x + 475
Step-by-step explanation:
In the equation I wrote, x is equal to the number of film rolls he needs to develop. You just put that number in for x and solve the equation. That will give you the amount of money Leo spends on his new hobby.

Answer:
x=√-5
Step-by-step explanation:
8-3x=√(4x^2+20)+8
-8 -8
-3x^2=√(4x^2+20)^2
-3x^2=4x^2+20
-4x^2=20
divide both sides by -4
x^2=-5
√(x^2)=√-5
x=√-5

1/32/5Which is the estimate of 398 x 1.9?
Answer:
800
Step-by-step explanation:
When we say estimate, we must estimate the 2 numbers to their closest answer:
398- 400 when rounded to the nearest 100
1.9- 2 when rounded to the nearest whole number
So we get the estimate equation as: 400×2= 800
Solution:
We know that:
[tex]\tex\text{398 can be rounded to 400, as 398 is close to 400.}[/tex][tex]\tex\text{1.9 can be rounded to 2, as 1.9 is close to 2.}[/tex]This means that:
[tex]398 \times 1.9[/tex] ≈ [tex]400 \times 2[/tex]Simplifying "400 x 2"
[tex]400 \times 2[/tex] [tex]= 800[/tex]Thus, the estimate of 398 x 1.9 is about 800.

Bananas cost $0.50 each, and apples cost $1.00 each.
(a) Elena would like to spend exactly $3.50 on buying fruits. If she buys 1 banana, how
many apples can she buy?
(b) Is it possible for Elena to buy 2 bananas, if she wants to spend exactly $3.50? Why or
why not?
Answer:
(a) 3 apples (b) no
Step-by-step explanation:
(a) 1 bannana = 0.50
3 apples = 3.00
total = 3.50
(b) Not possible because 2 bannanas = 1 dollar 3 bananas = 1.50 then 1.50 + 2.00 apples = 3.50

How do i figure out the degrees?
Answer:
41°
Step-by-step explanation:
This problem involving the Law of Cosines has been mostly worked for you. The value of the cosine is the solution to the remaining one-step linear equation. The inverse cosine function (cos⁻¹ or arccos) is used to find the angle from the value of the cosine.
-1125 = -1500·cos(A)
cos(A) = -1125/-1500 = 3/4 . . . . . divide by -1500 (this is the one step)
A = arccos(3/4) ≈ 41.4096°
The angle formed by the lines to the lampposts is about 41°.
__
Additional comment
If you find the angle using the ACOS( ) function of a spreadsheet, you will always get the result in radians. Most calculators offer the choice of units for angles, so be sure you set the mode appropriately.
In the calculator screenshot, there is a decimal point in the fraction to force the angle result to be displayed as a numerical value. Otherwise, this calculator shows cos⁻¹(3/4), which isn't terribly helpful.

A semicircle is drawn onto one of the shorter sides of a rectangle. The shorter side of the rectangle measures 4 centimeters. The area of the figure is 41. 4 square centimeters. What is the length of the longer side of the rectangle?Use 3. 14 for π. Enter your answer as decimal in the box
The length of the longer side of the rectangle is 8.78cm
Area of composite figureThe formula for calculating the area of a rectangle is expressed as:
A = lw
For a semicircle;
A = πr²/2
r is the radius
Area of the figure = lw + πr²/2
Substitute the given paramters
41.4 = 4w + π(2)²/2
41.4 = 4w + 6.28
4w = 41.4 - 6.28
4w = 35.12
w = 35.12/4
w= 8.78 cm
Hence the length of the longer side of the rectangle is 8.78cm

The temperature outside changed from 94°F to 46°F over a period of eight days. If the temperature changed by the same amount each day, what was the daily temperature change?
Answer:
6°F
Step-by-step explanation:
First, subtract 46 from 94 (94-46) and you will get 48.
Then, divide 48÷8 (because the time period is 8 days) and you will get 6.
Therefore, the daily temperature change is 6°F.

Find the length and width of rectangle CBED, and calculate its area.
Answer:
170 units
Step-by-step explanation:
60+60+25+25=170
The 60 and 60 can be found by adding the length, 20+35+5.
The 25 and 25 can be found by taking 55+8-(30+8) for the widths.
Answer:
Step-by-step explanation:
Length = DE =OP
OP = 5 + 20 + 35 = 60 ft
Length of the rectangle CBED = 60ft
Width CD = CJ - (DG +GJ)
= 55 - (8 + 30)
= 55 - 38
= 17 ft
Area of CBED = length * width
= 60 * 17
= 1020 ft²
