write 34.24 as a mixed numbers
Answer:
34 6/25
Step-by-step explanation:
A mixed number is a whole number in front of a fraction. Keep 34 as the whole number. .24 is really 24/100, but you can simplify it to 6/25.
If (-3, y) lies on the graph of y = 3^x, then y =
-1
1/27
-27
Answer:
1/27
Step-by-step explanation:
If (-3, y) lies on the graph of y = 3^x, then we can find y by filling in the given x and calculating y
They gave us that x is -3 (the first number in an ordered pair is the x).
y = 3^x
y = 3^(-3)
y = 1/(3^3)
**You "fix" a negative exponent by pushing across a fraction bar; that changes the sign of an exponent**
y = 1/27
Because3^3 is 3×3×3 is 27

During, an Experiment, The temperature of a solution changes from 9 4/5 F to 17 1/4 F.
What is the percent of increase in the temperature of the solution?
Enter your answer in the box as a percent rounded to the nearest hundredth
Using improper fractions, it is found that the percent of increase in the temperature of the solution was of 76.08%.
How to convert improper fractions to standard fractions?The conversion is made according to the following formula:
[tex]a\frac{b}{c} = a + \frac{b}{c} = \frac{ac + b}{c}[/tex]
In this problem, the initial temperature was given by:
[tex]9\frac{4}{5} = 9 + \frac{4}{5} = 9.8[/tex]
The final temperature was given by:
[tex]17\frac{1}{4} = 17 + \frac{1}{4} = 17.25[/tex]
What is the percent change?The percent change is given by the change divided by the initial temperature, and multiplied by 100%. Hence:
[tex]C = \frac{17.25 - 9.8}{9.8} \times 100\% = 76.02\%[/tex]

Answer:
22
Step-by-step explanation:
Let x represent the number of houses on each street. Normally, Jake delivers 7x papers, and Ryan delivers 3x papers. On the day when Ryan delivered 45 of Jake's papers, we have ...
(3x +45) > (7x -45)
90 > 4x . . . . . . . . . . . add 45 -3x to both sides
22.5 > x . . . . . . . . . . divide by 4
The number of houses on each street will be an integer, so the maximum number of houses on each street is 22.
_____
Additional comment
If Jake normally delivers more than 45 papers, then we must also have ...
7x > 45
x > 6 3/7
There must be at least 7 houses on each street.

Kelsey and Jeffrey were deciding how best to factor the expression 4x^2 - 100. Kelsey said this is a GCF question, but Jeffrey said it is a DOTS question. Who is correct and why?
Answer:
4 ( x - 5 ) x ( x + 5 )
Step-by-step explanation:
1- Factor the expression
2- Factor the expression
Answer:
They are both correct because you should use both to solve the question. To solve it you will have to find the GCF first and then you find the difference of two squares.
Step-by-step explanation:
4x^2 -100
[tex]4(x ^{2} - 25)[/tex]
This would be finding the Greatest common factor

The farmer has a very insufficient way of farming he is a fake farmer if he only plants 3 crops a row and than 12 in the next he most likely has no pattern but if we do trigonometrically mitochondria math we can figure out that his patter does exist but only to him. since the farmer goes but he goes up by four cuz 3 x 4 is a number 12 and than 12 x 4 is 48 which the farmers produce will all die on his crusty land.
If correct Brainliest
Answer:
11y+22
Step-by-step explanation:
Answer and Step-by-step explanation:
For this equation, you need to use the distributive property. Before we can solve this, we need to know what the distributive property is. (Important:) The distribute property is where a number is directly outside the parenthesis and is multiplied to each number inside the parenthesis.
With that being said, let's rewrite this expression. Because 11 is outside the parenthesis, multiply it to each of the numbers inside the parenthesis. The numbers 11 x 2 = 22, so:
(y + 2)11 = 11y + 22.
We can remove the parenthesis now that the equation has changed. The reason why the 11 is in front of the y is because it is a coefficient. Coefficients always are written before a variable, which is the y in this case.
So, the answer is 11y + 22.

The diagonal of a rectangle is 2under root 13cm.If its length and breadth are in the ratio 3:2, then find its area.
Answer:
Given :
The diagonal of a rectangle is 2 ✓13 cm.
The length and breadth are in the ratio
3:2.
To find :
The Area of the rectangle.
Solution :
Given that
The ratio of the length and breadth of a rectangle = 3:2
Let they be 3X cm and 2X cm
We know that
The diagonal of a rectangle = √(1²+b³)
units
The diagonal of the rectangle
= √[(3X)³+(2X)³] cm
= √(9x³+4x²) cm
=> √(13X²) cm
=> √13 X cm
According to the given problem
The diagonal of the rectangle = 2√13 cm
=> ✓13 X = 2 √13
=> X = 2√13/√13
=> X = 2 cm
If X = 2 cm then 3X=3(2) = 6 cm
If X = 2 cm then 2X = 2(2)=4 cm
Length = 6 cm
Breadth = 4 cm
We know that
Area of a rectangle = length breadth sq.units
Area of the given rectangle = 6 cm x 4 cm
= 24 cm²
