R is the midpoint of PQ. PR = 6x + 7 and RQ = 3x + 8, find the length of PQ.
Answer:
PQ = 18
Step-by-step explanation:
If R is the midpoint of PQ, then PR = RQ
⇒ 6x + 7 = 3x + 8
⇒ 3x = 1
⇒ x = 1/3
So PR = 6x + 7 = 6(1/3) + 7 = 9
and RQ = 3x + 8 = 3(1/3) + 8 = 9
⇒ PQ = PR + RQ = 9 + 9 = 18
Explain how you can multiply 4($5.97) without paper or calculator by thinking of $5.97 as 6−0.03 and then using the distributive property.
Answer:
you can can answer with mental math
for ex. 4 x 97 can be broken into 4 x 7 + 4 x 9
and the 5 dollars could be 4 x 5 add them up and your answer should be right
By using distributive property of multiplication over subtraction we got 4 (5.97) = 23.88 without actually multiplying 4 (5.97) .
What is distributive property of multiplication?This property states that when a number is multiplied by addition/subtraction of two number is same as multiplying this number with both the numbers individually and then adding/subtracting them.
let a, b, c are three numbers then distributive property of multiplication can be stated as :
a×(b ± c) =(a× b) ± (a ×c)
For Multiplying 4($5.97)
Write 5.97 = 6 -0.03
4 (5.97) = 4* ( 6 -0.03) = (4*6) -(4*0.03) (using distributive property)
⇒(4*6) -(4*0.03) = 24 - 0.12 = 23.88
Therefore without actually multiplying 4 (5.97) we got 4 (5.97) = 23.88 by using distributive property of multiplication over subtraction.

Julie earned a $1500 bonus at work for doing a good job. She placed part of the money in a regular savings account earning 2.5% annual interest. She placed the remaining amount in a money market account earning 5% interest annually. At the end of the year she earned four times more in the money market account than she did in the regular savings account. How much did Julie invest in the money market account at 5% interest? (Express your answer to the nearest dollar)
The amount of money Julie invested in the money market account at 5% interest is $600
How to find amount Julie invest in the money marketAccording to the question;
It follows that the total amount earned is; $1500. andLet, x and y be the initial allocated to savings and market account respectively, then;x + y = 1500
4 × (0.025 × x) = (0.05 × y)
Therefore;
x = y/2
Therefore, y + y/2 = 1500

solve the following proportion n-5/10 = n+4/2
Answer:
n = -25/4
Step-by-step explanation:
(n - 5)/10 = (n + 4)/2
10(n + 4) = 2(n - 5)
5(n + 4) = n - 5
5n + 20 = n - 5
4n = -25
n = -25/4
At the baseball game last weekend, the Smith, Jones, and Garcia families each bought snacks from the concession stand. The Smith family purchased 3 hot dogs, 1 drinks, and 4 pretzels for $19.50. The Jones family spent $10.00 on 2 hot dogs, 2 drinks, and a pretzel. The Garcia family bought 3 hot dogs, 2 drinks, and 2 pretzels for $15.
What is the cost of a drink?
Answer:
The cost of a drink is $1.5
Step-by-step explanation:
Let x be the cost of 1 hot dog , y be the cost of 1 drink and z be the cost of 1 pretzel
We are given that The Smith family purchased 3 hot dogs, 1 drinks, and 4 pretzels for $19.50.
So, 3x+y+4z=19.50 ---1
We are also given that The Garcia family bought 3 hot dogs, 2 drinks, and 2 pretzels for $15.
So, 3x+2y+2z=15 ---2
We are also given that The Jones family spent $10.00 on 2 hot dogs, 2 drinks, and a pretzel.
2x+2y+z=10 ---3
Substitute the value of y from 1 in 2 and 3
3x+2(19.50-3x-4z)+2z=15 and 2x+2(19.50-3x-4z)+z=10
-3x-6z+24=0----4 and -4x-7z+29=0 ---- 5
Substitute the value z from 4 in 5
[tex]-4x-7(\frac{-24+3x}{-6})+29=0[/tex]
x=2
Substitute the value of x in 4
-3(2)-6z+24=0
z=3
Substitute the value of x and z in 1
3(2)+y+4(3)=19.50
y=1.5
Hence the cost of a drink is $1.5

Adam’s balance at the end of June is $629.42.
What is the adjusted balance method?The adjusted balance method is an accounting method that bases finance charges on the amount(s) owed at the end of the current billing cycle after credits and payments post to the account.
Balance at the end of April = 626.45 + 37.41 + 44.50 = $708.36
Interest levied on $708.36= 708.36* (14.63/12) * 1/100
Interest levied on $708.36 = $8.64
So, balance on May 1st= 708.36+ 8.64 = $717
Balance at the end of May = 717-65.50+24.89-104.77 = $571.62
Interest levied on $571.62 = $571.62 * (14.63/12) * 1/100
Interest levied on $571.62=$6.97
So, balance on June 1st = $578.59
Balance at the end of June = 578.59-23.60 + 15+51.85 = $621.84
Interest levied on $621.84 = $621.84* (14.63/12) * 1/100
Interest levied on $621.84 =$ 7.58
So balance at the end of the june = 621.84 + 7.58 = $629.42
Therefore, Adam’s balance at the end of June is $629.42.

A. You need to draw a straight line that increases from left to right. Try and get the same amount of plots on the top and bottom of the line and go through one or two of the plots. Don't connect the dots, though.
B. This scatter plot demonstrates a positive association between a person's height and weight because the trendline increases from left to right. According to this data, as weight increases, so does height. The more someone weighs, the more likely they are to be tall.
Which modified box plot represents the data set? 39, 39, 3, 40, 46, 48, 60, 62, 62.
Answer:
To find this question, you first should put your data values in order from least to greatest. Doing so would look like this:

Kathleen jarred 12 liters of jam after 4 days. How much jam did Kathleen jar if she spent 6 days making jam? Assume the relationship is directly proportional.
Given parameters:
Number of liters of jam = 12 liters
Number of days = 4 days
Unknown:
Number of jams jarred in 6 days = ?
Solution:
Let us first find the rate of Kathleen in this jarring work;
Rate = [tex]\frac{Number of jams}{Number of days}[/tex]
Rate = [tex]\frac{12}{4}[/tex] = 3liters/day
Now, the number of jams in 6days;
Number of jams = Rate x number of days
Number of jams = 3 x 6 = 18jams
The number of jams jarred in 6 days is 18

IF NR = 8 ft, what is the length of arc NMP. Round to the nearest tenth.
Check the picture below.
since chords NQ and MP cross the center of the circle at R, that means that those two chords are diametrical chords and the angles made by both are vertical angles and thus twin angles, namely both are 18° as you see in the picture, so the angle NMP in magenta is really 162° + 18° + 18° = 198°, and we know the radius NR is 8.
[tex]\textit{arc's length}\\\\ s=\cfrac{r\pi \theta }{180}~~ \begin{cases} r=radius\\ \theta =\stackrel{degrees}{angle}\\[-0.5em] \hrulefill\\ r=8\\ \theta =198 \end{cases}\implies s=\cfrac{(8)\pi (198)}{180}\implies s\approx 27.6[/tex]
