Ralph has $10 in his wallet he wants to buy 5 pencils, 3 pens, 2 notebooks from the school store how much more money dose he need
Answer:
The correct answer is 1.75
Step-by-step explanation:
5 x 0.50 = 2.5
3 x 1.25 = 3.75
2 x 2.75 = 5.5
Then we want to add
2.5 + 3.75 + 5.5 = 11.75
Now, Subtract.
11.75 - 10.00 = 1.75
The total amount spent will be equal to $12, so the money added by Ralph will be equal to $2.
What are arithmetic Operations?The four fundamental operations of arithmetic are addition, subtraction, multiplication, and division of two or even more items.
Included in them is the study of integers, especially the order of operations, which is important for all other areas of mathematics, notably algebra, data management, and geometry.
As per the data given in the question,
The total money Ralph has is $10.
Price of each pencil = $0.50
Then, price of 5 pencil will be = 5 × 0.50 = $2.5
Price of each pen = $1.25
Then, the price of 3 pens will be = 3 × 1.25 = 3.75
Price of each notebook = $2.75
Then, the price of 2 notebooks will be = 2 × 2.75 = 5.5
Then, the total money spent by Ralph = 5.5 + 3.75 + 2.75 = 12
The money that he should have to add will be,
$12 - $10 = $2

Sarah’s neighbor offers to pay her $5 for every shark tooth she finds on the beach. After collecting only three shark’s teeth, Sarah decides to share the opportunity with her friend John. Sarah can find shark teeth twice as fast as John, but she can earn even more money with his help.
Sarah can use the expression 5(2j + 3 + j) to represent the amount of money she can earn.
Part 1: Writing Expressions: 25(10j + 18 + 5j)
Write an expression that looks like Sarah’s expression: 5(2j + 3 + j). Replace the coefficients so that your expression is not equivalent. You may use any number that you choose to replace the coefficients. Be sure to leave the variables the same. For example, 8(3j + 7 + 3j) looks like Sarah’s expression but is not equivalent.
Translate the algebraic expression you created in Question 1 to a verbal expression.
Twenty five times the sum of ten j plus 3 plus j
Part 2: Writing Equivalent Expressions
You will now use mathematical properties to create two expressions that are equivalent to the expression you created in Question 1. Make sure you show all steps in your work.
Using commutative property of addition, the expression in question 1 can be rewritten as follows:
25(10j + 18 + 5j) = 25(10j + 5j + 18)
Using distributive property of multiplication over addition, the expression in question 1 can also be rewritten as follows:
25(10j + 18 + 5j) = 250j + 450 + 125j
Use either the commutative property or combine like terms to create an equivalent expression.
Use the distributive property to create an equivalent expression.
Pick a number from 1 to 10. Use that number to verify your three expressions (the original, the one from 3a, and the one from 3b) are equivalent by substituting it into each expression. Show all your work for complete credit.
Part 3: Finish the Story
Write a few sentences to end Sarah’s story. How many shark teeth did she find? How many shark teeth did John find? How much money did Sarah earn?
Choose a method to present your assignment. You may submit your work in a Word Document or you may choose to develop a PowerPoint presentation or video recording of yourself. Use your creativity! Make sure to include the information from all three parts in your Word Document or presentation.
Answer:
the answer is in PREZI, just search up this question and u will find it : )

write the equation of this line in y= mx + b form:
Answer:
y = 2.5x + 3
Step-by-step explanation:
y = mx + b
y = 2.5x + 3
As you can see, each unit is not 1, its 0.5. We need to go up 5 times, and so 0.5 times 5 gives us 2.5, and thats how i got my slope.
I got 3 as my y-intercept because it's were the line intersects the y axis.
Hope this helped!
Have a supercalifragilisticexpialidocious day!
Answer:
y=5x+3
Step-by-step explanation:
Slope: y2-y1 over x2-x1 so it will be 3-(-2) over 0-(-1) and the answer will be 5.
Y intercept: In order to find the y intercept it is necessary to replace the y an x coordinate in the equation: y= mx+b and replace 3=5(0)+b... simplifying would be 3=b
so the final answer would be y=5x+3
PQ is a diameter of a circle with centre If angle PQR=55 ,SPR=25 and angle PQM=50
Find QPR, QPM, and PRS
Answer:
m∠QPR = 35° m∠QPM =40° m∠PRS = 30°
Step-by-step explanation:
ΔPRQ is a right triangle with right angle at R. So m∠QPR = 90 - 55 = 35
ΔQPM is a right triangle with right angle at M. So m∠QPM = 90 - 40 = 40
Arc RQ = 2(35) = 70 and arc SR = 2(25) = 50.
So arc PS = 180 - (arc RQ + arc SR) = 180 - (70 + 50) = 180 - 120 = 60
Now arc PS is the intercepted arc for ∠PRS.
Therefore, m∠PRS = 60/2 = 30
I used the fact that an inscribed angle has a measure 1/2 the measure of the intercepted arc several times. Also, I used the fact that the acute angles of a right triangle are complementary. And, finally I used the fact that an inscribed angle in a semicircle is a right angle.

What is the distance of
CD
given that
C (5,-2) and D (-3,8)
Leave your answer as a square root.
Answer:
CD = [tex]\sqrt{164}[/tex]
Step-by-step explanation:
Calculate the distance d using the distance formula
d = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]
with (x₁, y₁ ) = C(5, - 2) and (x₂, y₂ ) = (D(- 3, 8)
d = [tex]\sqrt{(-3-5)^2+(8+2)^2}[/tex]
= [tex]\sqrt{(-8)^2+10^2}[/tex]
= [tex]\sqrt{64+100}[/tex]
= [tex]\sqrt{164}[/tex]
= 2[tex]\sqrt{41}[/tex] ← in simplest form
As, we have C (5, - 2) and D (- 3, 8), to find CD let's use distance formula :
[tex] \underline{\boxed{\tt{Distance \: between \: two \: points = \sqrt{(x_2 - x_1)^{2} + (y_2 - y_1)^{2}}}}}[/tex]
Here,
x₁ = 5x₂ = - 3y₁ = - 2y₂ = 8So, by filling values :
[tex] \sf : \implies CD = \sqrt{(-3 - 5)^{2} + (8 - (-2))^{2}}[/tex]
[tex] \sf : \implies CD = \sqrt{(-8)^{2} + (8 +2))^{2}}[/tex]
[tex] \sf : \implies CD = \sqrt{64 + (10)^{2}}[/tex]
[tex] \sf : \implies CD = \sqrt{64 + 100}[/tex]
[tex] \sf : \implies CD = \sqrt{164}[/tex]
Hence, distance of CD is [tex] \bold{\sf \sqrt{164}.}[/tex]
Eloise runs 1 3/4 miles on Monday and 2 3/4 on Tuesday how many miles do she run
Answer:
4.5
Step-by-step explanation:
1+2=3
3/4+3/4=6/4=1.5
3+1.5=4.5
Eloise ran a total of 9/2 miles, which can also be expressed as 4.5 miles.
To find out the total number of miles Eloise ran, we need to add the distances she ran on Monday and Tuesday.
On Monday, Eloise ran [tex]1\frac{3}{4}[/tex] miles.
On Tuesday, she ran [tex]2\frac{3}{4}[/tex] miles.
To add these distances, we need to find a common denominator for the fractions.
The least common multiple of 4 and 4 is 4.
Converting the mixed numbers to improper fractions:
[tex]1\frac{3}{4} = \frac{(1 \times 4 + 3)}{4}[/tex]
[tex]= \frac{7}{4}[/tex]
[tex]2\frac{3}{4} = \frac{(2 \times 4 + 3)}{4}[/tex]
[tex]= \frac{11}{4}[/tex]
Now, we can add the fractions:
7/4 + 11/4
= 18/4
Simplifying the fraction:
18/4
= 9/2
Therefore, Eloise ran a total of 9/2 miles, which can also be expressed as 4.5 miles.

ACME Company's expected sales can be modeled by g(t) = 13 – 21? + 4t - 7, where g(t) is measured in thousands
of dollars and t is the number of years after 2008. Find the average rate of change in expected sales from 2009 to
2015.
Select one:
O a. -$45,000
O b. $45,000
O c. $36,000
O d. $270,000
You can use the given function to evaluate the expected sales at year 2009 and 2015 and use the net difference divided by time as the average rate of change.
The average rate of change in expected sales from 2009 to 2015 is given by $12,059,941
How to find the average rate of change of something?Let the thing that is changing be y and the thing with which the rate is being compared is x, then we have the average rate of change of y as x changes as:
[tex]\text{Average rate} = \dfrac{y_2 - y_1}{x_2 - x_1}[/tex]
where when
[tex]x = x_1, y = y_1\\and \\x = x_2, y = y_2[/tex]
Using the above method to calculate the needed average rateSince the sales is given by the function [tex]g(t) = t^3 - 2t^2 + 4t - 7[/tex], and the inputs are 2009 and 2015, thus, evaluating g(t) (sales) at those values of t, we get:
[tex]g(2009) = 8023737057[/tex] (replaced 2009 with t and calculated)
[tex]g(2015) = 8096096703[/tex] (replaced 2015 with t and calculated)
Using these values to calculate the average rate
[tex]\text{average rate} = \dfrac{g(2015) - g(2009)}{2015 - 2009} = \dfrac{72359646}{6} = 12059941\\[/tex]
Thus,
The average rate of change in expected sales from 2009 to 2015 is given by $12,059,941

x = 135-115
x = 20
Please Make Me Brainlist
Answer:

Step-by-step explanation:
first look at the line which says a and 135, they add up to 180 so
a + 135 =180
a= 180-135
a= 45
Then to find the x we will have to add all the angles inside the triangle which would add up to 180
So,
x+115+45=180
x+160=180
x=180-160
x=20
