Answer:
b. 5z-10 = 5(z-2) c. c-2c^2= c(1-2c) d. r+r+r+r= r(1+1+1+1)= 4r e. 2x-(1/2) = (1/2)(4x-1)
Explanation:
you just need to find a common factor that you can divide out of each term. ex. with the 5z-10 both 5z and 10 are divisible by 5, so you can factor that out. to check the answers just multiply it. if you still don't get it, look up "factoring binomials"

how do I find the value of H in: h + 4 1/2 = 7
Answer:
5/2 or 2 1/2, or 2.5
Step-by-step explanation:
We know that 4 1/2 is 4.5.
Take 4.5 to the other side.
h=2.5
By the way, can you follow me on Brainly?
Thanks!
Answer:
5/2, or 2 1/2
Step-by-step explanation:
To find the value of h you want to get h by itself, so you must subtract 4 1/2 from both sides of the equation. 4 1/2 can be rewritten as 9/2, but you must find a common denominator between 7 and 9/2. A common denominator can be 2, if 7 is changed into 14/2. The equation is now 14/2 - 9/2, which gives you 5/2 or 2 1/2.
Someone help me please show me how you got it to please
Answer:
See explanation
Step-by-step explanation:
The hypotenuse is the longest side of a triangle.
You could either add a point at (3,2) or (6,9) to make a right triangle and get the same answer, but for the sake of looking at it right-side-up, I'd use (3,2).
Now, you can use the distance vertically (y coordinate) from the top point to the bottom point ( 9 to 2 ) as your first side length. 9-2= 7, so 7 is that side length.
Then, you can use the distance horizontally (x coordinate) from the bottom left point (3,2) to the bottom right point (6,2). 6-3= 3, so 3 is that side length.
Now for the Pythagorean Theorem (a^2 + b^2 =c^2)
7^2 + 3^2 = c^2
49+9=c^2
58=c^2
c= [tex]\sqrt{58\\\\}[/tex] is the distance between points
The conditional relative frequency table below was generated by column using frequency table data comparing the number of calories in a meal to whether the meal was prepared at home or at a restaurant.
A 4-column table with 3 rows titled number of calories and location of meal preparation. The first column has no label with entries greater than or equal to 500 calories, less than 500 calories, total. The second column is labeled home with entries 0.15, 0.85,1.0. The third column is labeled restaurant with entries 0.55, 0.45, 1.0. The fourth column is labeled total with entries 0.28, 0.72, 1.0.
A nutritionist attempts to determine an association between where food is prepared and the number of calories the food contains. Which is most likely true?
An association cannot be determined because the value 0.55 is similar to the value 0.45.
There is an association because the value 0.15 is not similar to the value 0.55.
There is an association because the sum of each column is 1.0.
An association cannot be determined because the sum of the rows going across is not 1.0.
There is an association because the value 0.15 is not similar to the value 0.55
For the nutritionist to determine whether there is an association between where food is prepared and the number of calories the food contains, there must be an association between two categorical variables.
The conditions that satisfy whether there exists an association between conditional relative frequencies are:
1. When there is a bigger difference in the conditional relative frequencies, the stronger the association between the variables.
2. When the conditional relative frequencies are nearly equal for all categories, there may be no association between the variables.
For the given conditional relative frequency, we can see that there exists a significant difference between the columns of the table in the picture because 0.15 is significantly different from 0.55 and 0.85 is significantly different from 0.45
We can conclude that there is an association because the value 0.15 is not similar to the value 0.55

d) how did you apply proportional reasoning as you worked through these problems?
Answer:
pls give brainlist
Step-by-step explanation:
a. [tex]\frac{50 blocks (L)}{9 blocks(W)\\}[/tex] 50 x 9 = 450. A=450
b. I can scale the unit rate of the area given above and largen the area of the map. Ex. [tex]\frac{7}{3}[/tex]=[tex]\frac{21}{6}[/tex] <---(scaled by 2)
Then we can enlarge it however we want so,

Step-by-step explanation:
Find the derivative of f(x) = -4x2 + 11x at x = 10.
a) 19.5
b) -69
c) 30
d) -300
Answer:
-69 (Answer b)
Step-by-step explanation:
Apply the power rule for differentiation:
(d/dx){-4x^2 + 11x} = -8x + 11
Now substute 10 for x:
f '(x) = -8(10) + 11 = -80 + 11 = -69 (Answer b)
Answer:
b
Step-by-step explanation:
Using the power rule to differentiate each term
Given
f(x) = - 4x² + 11x , then
f'(x) = - 8x + 11
At x = 10
f'(10) = - 8(10) + 11 = - 80 + 11 = - 69 → b

If t= -3, then 3t^2 +5t +6 equals
A. -36
B. -6
c. 6
D. 18
Answer:
D
Step-by-step explanation:
substitute t=-3 in the equation
3(-3) squared +5(-3)+6=18
Step-by-step explanation:
According to the question , value of t = (-3) . So on directly putting t = (-3) in expression we have ,
[tex]\tt \to 3t^2 +5t+6 \\\\\tt\to 3(-3)^2+5(-3)+6 \\\\\tt\to (3)(9)-15 +6 \\\\\tt\to 27 - 15 +6 \\\\\tt\to \boxed{\orange{\tt 18 }}[/tex]
7+6-9(-2)+(-3) simplify step by step plzzzx
=13+18-3
=31-3
=28
the answer is 28
Answer:
28
Step-by-step explanation:
According to Order of Operations rules, we must multiply here before adding or subtracting.
In 7 +6 - 9(-2) + (-3) the very first thing we must do is to evaluate the product -9(-2). This comes out to 18, so now we have:
7+6 + 18 +(-3).
Next, remove the remaining parentheses, obtaining:
7 + 6 + 18 - 3, or
13 + 15 = 28

What is the equation of the line that passes through (4, 3) and (-4, -1)?
y = 2 x + 7
y = + 1
2 x + 1
y = + 7
Answer:
Step-by-step explanation:
First find the slope of the line
(4 , 3) ; x₁ = 4 ; y₁ = 3
(-4,-1) ; x₂ = -4 ; y₂ = -1
slope [tex]= \frac{y_{2}-y_{1}}{x_{2}-x_{1}}\\\\[/tex]
[tex]=\frac{-1-3}{-4-4}\\\\=\frac{-4}{-8}\\\\=\frac{1}{2}[/tex]
m = 1/2 , and take any one point (4 , 3)
y -y1 = m(x - x1)
[tex]y - 3 = \frac{1}{2}(x - 4)\\\\y -3 = \frac{1}{2}x-4*\frac{1}{2}\\\\y - 3 =\frac{1}{2}x - 2\\\\y = \frac{1}{2}x - 2 + 3\\\\y =\frac{1}{2}x + 1[/tex]

A survey of 120 twelfth-graders finds that 36% were carrying more than $15 on the day of the survey. Use the margin of error to complete the following. Round to the nearest whole percent. An interval that will likely include the proportion of students in the population of twelfth-graders who carry more than $15 is ?
Answer:
An interval that will likely include the proportion of students in the population of twelfth-graders who carry more than $15 is 960
Step-by-step explanation:
For example, Condition 1: n(.05)≤N
• The sample size (10) is less than 5% of the population (millions of musicians), so
the condition is met.
• Condition 2: np(1-p)≥10
• =
2
10
= .2
• 1 − = 10 .2 1 − .2 = 1.6 . This is less than 10 so this condition is not
met.
It would not be practical to construct the confidence interval.
A student bought some markers in a pads of paper if the marker cost $2 each in the pads of paper cost $4 each he brought a items and all and spent $26 how many markers and how many pads of paper did he buy?
Answer:
$4
Step-by-step explanation:
We need to set up an algebraic expression to solve this problem:
Let n= cost of a notepad
Let p= cost of a pen
First set up an expression for Cynthia's purchase:
cost of notepads*number of notepads + cost of pens*number of pens = total cost
n*2 + p*3 = 40.30
Rewrite as:
2n + 3p = 40.30
Next, set up an expression for Annie's purchase:
Here we will be using the same variables
n*3 + p*5 = 61
Rewrite as:
3n + 5p =61
Now, set up a system of equations:
2n + 3p = 40.30
3n + 5p =61
A system of equations can be solved in several ways, here I will use the addition/elimination method
For this method one of the variables must be able to be eliminated
Step 1: Pick a variable to eliminate
Here I will eliminate n
Step 2: make the selected variables in the equations equal and opposite so that they cancel out when the equations are added together
(2n + 3p = 40.30)(-3)
(3n + 5p =61)(2)
-6n - 9p = -120.90
6n + 10p = 122
Step 3: add vertically
-6n - 9p = -120.90
6n + 10p = 122
p = 1.10
Step 4: Figure out the other variable by inputting the answer you just got back into the original equation
2n + 3(1.10) = 40.30
2n + 3.30 = 40.30
-3.30 37
2n = 37
/2 /2
n = 18.5
One notebook = $18.50
One pen= $1.10
18.50+1.10= $19.60
2nd step
We must first set up an algebraic expression
total=15 pencils
total=9 pens
The total amount is the price of one pencil*15
To figure out one pencil:
10 pencils are $24
1 pencil is $2.40
Total= $36
9 pens = 36
Therefore 1 pen is $4

1. Matt used a cup shaped like a cylinder to drink his morning milk. The dimensions of
the container are shown below.
width- 8 cm
height-12cm
Which measurement is closest to the area of the base of the container in square
centimeters?
Answer:
50.29 cm²
Step-by-step explanation:
Base area of a cylinder = πr²
π = 22/7
r = radius
For circular objects, the width is the same as the diameter of the object
the diameter is the straight line that passes through the centre of a circle and touches the two edges of the circle.
A radius is half of the diameter
radius = 8/2 = 4cm
Base area = (22/7) x 4² = 50.29 cm²
