Answer:
he bought 12 pencils
Step-by-step explanation:
20 - 5.12 = 14.88
14.88 / 1.24 = 12
Answer:
[tex]he \: give \: 20 \: to \: cashier \: and \: recieve \: 5.12 \\ so \: 20 - 5.12 = 14.88 \\ 1.24per \: pencil \: h e \: buy \: x \: penil \: then \\ x \times 1.24 = 14.88 \\ x = \frac{14.88}{1.24} = 12 \\ 12 \: number \: of \: pencil \: \\ thank \: you[/tex]

What is the equation of the line that passes through the point (4, -4) and has a slope of -5/2
Answer:
y = -5/2x + 6
Step-by-step explanation:
y = -5/2x + b
-4 = -5/2(4) + b
-4 = -10 + b
6 = b
What is the approximate area of a circle with a radius of 15 ft? Use your calculator button for it Enter your answer in the box. Round to four decimal places ft2
Answer:
706.8583
Step-by-step explanation:
[tex]Area = \pi r^2[/tex]
[tex]Area = \pi 15^2[/tex]
[tex]Area = \pi 225[/tex]
[tex]Area = 3.14159265*225[/tex]
[tex]Area = 706.85834625[/tex]
Round it and you get 706.8583
A computer program in Shannon’s computer carries out a single mathematical operation in 1.5 × 10-6 seconds. How much time would the program take to complete 2.5 × 103 mathematical operations?
1/1.5 * 10^-6 = 2500/x
x = 1.5 * 10^-6 * 2500
x = 0.00375 or 3.75 * 10^-3 second.

There are 30 people entered into a contest. How many ways can the contestants win first, second, third, and fourth place?
Answer:
I am not entirely sure so don't kill me if it's wrong qwq
Step-by-step explanation:
Well assuming P represents the number of outcomes, n the number of competitors and r the number of places to be awarded.
P = n!
(n−r)!
P=30! /
(30-4)!
P=30!/26!
P=657720
Find the area of the following shapes:
Answer:
Area = 20 square units
Step-by-step explanation:
=> We know that;
Base 1: 3 units
Base 2: 7 units
Height: 4 units
=> Now let's come up with a congruent base first:
[tex]\frac{(3 + 7)}{2}[/tex] = final base
10/2 = final base
5 = final base
=> Finally, Area of the trapezoid:
A = Final Base * Height
A = 5 * 4
A = 20 square units

Sara makes some Blue paint. She mixes yellow, red and brown in the ratio 4: 6: 9. He uses 340 ml of the yellow paint. How much Blue paint does he make?
Answer:
1615
Step-by-step explanation:
the equation that represents the amount of yellow paint used =
(ratio of yellow paint / sum of ratios) x p = 340
p = blue paint
4 / 19 x p = 340
p = 1615

Answer:
Use Pythagorean to find the missing side lengths.It assumed a and b are legs and c is the hypotenuse.All numbers are rounded to the nearest tenth.#10
[tex]c = \sqrt{3^2+4^2} = \sqrt{25} = 5[/tex]#11
[tex]b = \sqrt{16^2-6^2} = \sqrt{220} = 14.8[/tex]#12
[tex]c = \sqrt{4^2+2^2} = \sqrt{20} = 4.5[/tex]#13
[tex]a = \sqrt{4.2^2-3.5^2} = \sqrt{5.39} = 2.3[/tex]PLEASE HELP!!

what is the missing exponent?
17 / 17^4 = 17^8
Answer:
The missing exponent is 12.
Step-by-step explanation:
Whenever you divide same-base exponents, you keep the base numbers the same and subtract the exponents.
The only number subtracted by 4 that would give you 8 is 12.
Or, if the numbers are larger, it is must easier to add the exponent in the answer to the number in the equation.
For example,
[tex]17^4+17^8=17^1^2[/tex]
Therefore, the missing exponent is 12.
Because: [tex]17^1^2/17^4=17^8[/tex]
identify the domain and range of the function graphed below
umm... can i ask if, where is the graph you say?
which is greater 5/8 or 0.37
Answer:5/8
Step-by-step explanation:
describe the transformation of f(x) = sin x to g(x) = sin ( x + pi/3)
The function f(x) = sinx will be shift left side by π/3 units and becomes g(x) = sin(x + π/3) and period of the transformed function becomes 2π
What is a function?It is defined as a special type of relationship and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
We have a primary function:
f(x) = sinx and
The transformed function is:
[tex]\rm g(x) = sin(x+\frac{{\pi} }{3} )[/tex]
If we replace x to [tex]\rm x + \frac{\pi}{3}[/tex] it will shift to the left by π/3 units.
For a period of the transformed function is given by:
[tex]\rm T = \frac{2\pi}{n}[/tex]
Where n is used to find the period of the function.
n = 1
t = 2π
Thus, the function f(x) = sinx will be shift left side by π/3 units and becomes g(x) = sin(x + π/3) and period of the transformed function becomes 2π

A business owner wants to have the front window of her store painted and is considering two
artists for the job. Tiana has quoted a flat rate of $292 for the job. Denise's quote is $39 per
hour, plus $19 to cover the cost of materials. Depending on how long it takes Denise to paint
the window, these two could end up charging the same amount. How long would Denise have
to take? How much would it cost?

Step-by-step explanation:
Write the equation of the circle with center (0, 0) and (3, 6) a point on the circle.
Answer:
Step-by-step explanation:
We will use the standard form of a circle to solve for the radius and then fill it back in. h is 0, k is 0, x is 3, and y is 6:
[tex](3-0)^2+(6-0)^2=r^2[/tex] and
[tex]3^2+6^2=r^2[/tex] and
[tex]9+36=r^2[/tex]
Therefore, r-squared is 45, so the circle's equation in standard form is
[tex](x-0)^2+(y-0)^2=45[/tex] or more simply:
[tex]x^2+y^2=45[/tex]
