Answer: 24
Step-by-step explanation:
Let the total number of problems be x.
After 15 minutes, [tex]x-\frac{1}{4}x=\frac{3}{4}x[/tex] problems are left.
After another 15 minutes, [tex]\frac{3}{4}x\left(1-\frac{1}{3})=\frac{3}{4}x\left(\frac{2}{3} \right)=\frac{1}{2}x[/tex] problems are left.
This is equal to 12, meaning x = 24.
If a²+b²=8ab, determine (a+b) in terms of a and b
[The question's not wholly right! Since, (a+b) has a and b in it, it already is in terms of a and b. Here, we'll be representing (a+b) in terms of ab]
Answer:
[tex]\mathsf{\sqrt{10ab} }[/tex]
Step-by-step explanation:
We have the rules of indices, one of which is:
[tex]\boxed{\large{\mathfrak{(a+b)^2=a^2+b^2+2ab}}}[/tex]
Indices are the powers, the numbers written as superscript in front of a variable or the numbers that come along with "^". It shows how many times a number is to be multiplied by itself.
In the question, we're provided with one equation, i. e.,
a² + b² = 8ab . . . . . . . . (¡)And, were asked to find out the value of (a+b) in terms of ab.
The above rule has variables that fit in the question efficiently!
So, instead of solving for (a+b), we'll be solving for (a+b)², then go for (a + b):
=> (a + b)² = (a² + b²) + 2ab
from eqn. (¡):
=> (a + b)² = 8ab + 2ab
=> (a + b)² = 10ab
taking under root on both the sides:
=> (a + b) = [tex]\mathsf{\sqrt{10ab} }[/tex]
That's the answer, [tex]\mathsf{\sqrt{10ab} }[/tex]!

Note: I got it right on the same test you took as me.
The value of time period for the equation is 8.
What is a word problem?A word problem is a verbal description of a problem situation. It consists of few sentences describing a 'real-life' scenario where a problem needs to be solved by way of a mathematical calculation.
For the given situation,
The population of insects is increasing by 9% each week = 0.09
At the beginning of the experiment, number of insects = 16
Number of insects increased per week
⇒ [tex]16+16(0.09)[/tex]
Let the time period be x.
Number of insects increased after 8 weeks can be found by the equation,
[tex]Future Amount = 16 (1 + 0.09)^{x}[/tex]
⇒ [tex]Future Amount = 16 (1 + 0.09)^{8}[/tex]
Hence we can conclude that the value of time period for the equation is 8.

A cookie recipe calls for 2 eggs and makes 3 dozen cookies. How many dozens of cookies could you make with a dozen eggs
Answer: 18 dozen cookies.
Step-by-step explanation: If 2 eggs make 3 dozen cookies and you have a dozen eggs divide 12/2 = 6. Then multiply 6*3 = 18.
Answer:
18 dozen cookies
Step-by-step explanation:
2 eggs makes 36 cookies
That means 2x=36
x=18
Now plug that into the equation.
12(18)=216

Rearrange x = 3g + 2 to make g the subject.
Answer:
In order to make g as the subject, we have only g on the left side and rest of the terms are denoted on the right. So, we consider it as X=3g+2 and switch to other side's 3g+2=x. It has to divide both sides by 3 and literally consider for g=1/3x-2/3 and therefore answer is g=1/3X-2/3.
What’s the rise over run pleas???
9514 1404 393
Answer:
-1/5
Step-by-step explanation:
To find the ratio of rise to run on a graph, it is convenient to start by looking for points where the graph crosses the intersection of grid lines. This lets you read the exact coordinates of the points, without any guessing.
In the attachment, the grid crossings we chose are circled.
The "rise" is the vertical distance between the points. If the right point is lower, the "rise" is negative.
The "run" is the horizontal distance between the points.
The reason for choosing grid crossings is that it then becomes fairly easy to count the grid lines between the points, vertically and horizontally.
On this graph, the "rise" is -1 for a "run" of 5. Then the slope, or ratio of rise to run, is ...
m = rise/run = -1/5 . . . . . . slope of the line

angle 1 and angle 2 form a linear pair. if m angle 1= x + 47, and m angle 2 = x-12 find the measure of angle 1
Answer:
215/2
Step-by-step explanation:
A linear pair means that the angles equal 180 degrees.
If added together 1 and 2 equal to 180 degrees, then the equation should be x+47+x-12=180. Then solve and simplify.
x+47+x-12=180
2x-35=180
2x=215
x=215/2
What are the solutions to x^2-2x+5=0
Answer:
x = 1 ± 2i
Step-by-step explanation:
x² - 2x + 5 = 0 ( add 5 to both sides )
x² - 2x = - 5
Using the method of completing the square
add ( half the coefficient of the x- term)² to both sides
x² + 2(- 1)x + 1 = - 5 + 1
(x - 1)² = - 4 ( take square root of both sides )
x - 1 = ± [tex]\sqrt{-4}[/tex] = ± 2i ( add 1 to both sides )
x = 1 ± 2i ( that is the solutions are complex )
Answer:
[tex]x=1\pm2i[/tex]
or
[tex]x=1+2i[/tex]
[tex]x=1-2i[/tex]
Step-by-step explanation:
All equations of the form [tex]ax^2+bx+c=0[/tex] can be solved using the quadratic formula: [tex]x = \frac{-b \pm \sqrt{b^2-4ac}}{2a}[/tex]
Quadratic formula gives two solutions, one when ± is addition add one when it is subtraction.
[tex]x^2-2x+5=0[/tex]
Equation is in standard form: [tex]ax^2+bx+c=0[/tex]
Substitute 1 from a, [tex]-2[/tex] for b, and [tex]5[/tex] for C in the quadratic formula, [tex]\frac{-b\pm \sqrt{b^2-4ac}}{2a}[/tex]
[tex]x=\frac{-\left(-2\right)\pm \sqrt{\left(-2\right)^2-4\times \:1\times \:5}}{2}[/tex]
Multiply -4 × 5:
[tex]x=\frac{-\left(-2\right)\pm \sqrt{\left(-2\right)^2-4\cdot \:1\cdot \:5}}{2}[/tex]
Add 4 + -20:
[tex]x=\frac{-\left(-2\right)\pm \:4i}{2}[/tex]
* the opposite of -2 is 2:
[tex]x=\frac{2\pm 4i}{2}[/tex]
Now, solve equation:
[tex]x=\frac{2+4i}{2}[/tex]
Divide 2 + 4i by 2:
[tex]x=1-2i[/tex]

Answer:

Step-by-step explanation:
To solve this we're going to use Polynomial multiplication, starting by multiplying (x-2)(x+1) = x^2 - 2x + x - 2 = x^2 - x - 2. Next, we will multiply (x^2 - x - 2)(x+ 5) = x^3 + 5x^2 -x^2 - 5x -2x -10 = x^3 + 4x^2 - 7x - 10.

2.A baker has 400kg of flour on the first day of the month and uses no flour that day. How much will he have at closing time on the 17th day of the month, if he uses 24 kg each day after that?
1. At the end of the 5th week he would have saved a total of $700
2. The amount of flour he would have at the closing time on 17th of the month will be 16kg
1.
Azad amount = $500
He wants to go on a holiday but he lacks sufficient money. This means the $500 in his possession is not enough.
He decided to save $40 dollars per week for a number of weeks to make up the deposits.
let
w = number of weeks
Therefore, his saving for any number of weeks will be
40wThe amount he would have saved for 5 weeks will be
40×5=$200
The total amount in his possession at the end of the fifth week will be 200 + 500 = $700
2.
The baker has 400 kg of flour. The first day of the month he didn't use any flour. This means on the first day of that month the flour was still 400 kg. The amount he has on the 17th day of the month can be calculated below.
The 17th day simply implies he used the flour for 16 days, the first day of the month he didn't use anything. He uses 24 kg for each day. Therefore the amount he uses for 16 days will be
16×24=384 kgThe amount he has at the closing time of 17 days of the month will be

Find the direct variation.
if y=28 when x= 168, find y when x =108.
Answer:
18
Step-by-step explanation:
168 : 28 : : 108 : y
168 / 28 = 108 / y
6 = 108 / y
6 * y = 108
y = 108 / 6
y = 18
Answer:
y = 18
Step-by-step explanation:
Given y varies directly as x then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition y = 28 when x = 168
28 = 168k ( divide both sides by 168 )
[tex]\frac{28}{168}[/tex] = k , that is
k = [tex]\frac{1}{6}[/tex]
y = [tex]\frac{1}{6}[/tex] x ← equation of variation
When x = 108 , then
y = [tex]\frac{1}{6}[/tex] × 108 = 18
