Answer:
65% of the beads were used to make the bracelet.
Step-by-step explanation:
40% of the beads were blue which means 60% of the beads were red. If all the blue beads were used that means 40% was used so you add the 25% of the red beads that were used which is why the answer is 65%.

Answer:
the anwser is 242
Step-by-step explanation:
I dont see a q anywhere but you would sub p and 9 and do the equation so times 10 and 9 and then distribute 22 or in your calculator jus enter 22(90-79) and you would get 242
e total cost of Anja's trip to the dentist was $628.35. She paid a flat fee of $89.95 which included the checkup an
aning and then had 4 cavities filled, each of which cost the same amount. Which shows the correct equation and
ue of x, the cost of each cavity filling?
4x+89.95=628.35; X = $134.60
4(89.95) + X = 628.35
X = $268.55
4x+89.95=628.35; X= $179.58
A(89.95)+ x = 628.35
X = $538.40
9514 1404 393
Answer:
(a) 4x+89.95=628.35; x = $134.60
Step-by-step explanation:
The total cost (628.35) is the cost per cavity (x) times the number of cavities (4), added to the flat fee (89.95). The equation for that is ...
4x +89.95 = 628.35
The solution to that is ...
x = (628.35 -89.95)/4 . . . . . subtract the constant, divide by 4
x = 134.60
Solve the equation. \dfrac32 + b = \dfrac74 2 3 +b= 4 7 start fraction, 3, divided by, 2, end fraction, plus, b, equals, start fraction, 7, divided by, 4, end fraction b=b=b, equals
Given:
The equation is
[tex]\dfrac{3}{2}+b=\dfrac{7}{4}[/tex]
To find:
The value of b.
Solution:
We have,
[tex]\dfrac{3}{2}+b=\dfrac{7}{4}[/tex]
Subtracting both sides by [tex]\dfrac{3}{2}[/tex], we get
[tex]b=\dfrac{7}{4}-\dfrac{3}{2}[/tex]
[tex]b=\dfrac{7-2(3)}{4}[/tex]
[tex]b=\dfrac{7-6}{4}[/tex]
[tex]b=\dfrac{1}{4}[/tex]
Therefore, the value of b is [tex]\dfrac{1}{4}[/tex].

What is the value of X what is the measure of 2 PLEASE HELPPP
Answer:
x = 11 , m∠2 = 31
Step-by-step explanation:
We know that m∠1 is equal to both 6x+8 and 74
Therefore, 6x+8 = 74
And 6x = 66
x = 11
To find m∠2, we just plug in the value of x that we got earlier
(7x-2) + m∠2 = 106
(77-2) + m∠2 = 106
m∠2 = 31
If 6 days ago was Wednesday, what day will it be 701 days from now?
A Wednesday
B Thursday
C Friday
D Saturday
E Sunday
show work!!
Answer:
Friday
Step-by-step explanation:
If 6 days ago was Wednesday, that means 6 days ago was Thursday. Every seven days, it will be Thursday again, so we can do 701/7 and see how many weeks fit equally. It is 100 weeks and 1 day. That means that Thursday would be in 100 weeks, or 700 days. Since there is one day left, it would be Friday. Friday is your answer.
The day after 701 days from today if, 6 days ago was Wednesday is Friday, so option C is correct.
What is division?One of the fundamental mathematical operations is division, which involves breaking a bigger number into smaller groups with the same number of components.
Given:
If 6 days ago was Wednesday,
If 6 days ago was Wednesday, then it will be Thursday today,
Calculate the day after 701 days as shown below,
The day = 701 / total days
As you can see, the Thursday will be repeated after 7 days,
Here, 1 will be the reminder, then one day after Thursday will be Friday.
Thus, after 701 days, it will be Friday.

A grocery store offers a 15% discount on your entire purchase when you spend more than $60. You have $85 to spend on groceries and the cost of the groceries in your cart is currently $60. The inequality 0.85(a+60)≤85 represents the cost a (in dollars) of groceries that you can add to your cart. Graph the solution of the inequality.
0.85(a + 60) ≤ 85
0.85a + 51 ≤ 85
-51 on both sides
0.85a ≤ 34
/0.85 on both sides
a ≤ 40
Answer:
a ≤ 40

Step-by-step explanation:
Set A of six numbers has a standard deviation of 3 and set B of four numbers has a standard deviation of 5. Both sets of numbers have an equal mean. If the two sets of numbers are combined, find the variance.
Given:
[tex]\sigma_A=3[/tex]
[tex]n_A=6[/tex]
[tex]\sigma_B=5[/tex]
[tex]n_B=4[/tex]
[tex]\overline{x}_A=\overline{x}_B[/tex]
To find:
The variance. of combined set.
Solution:
Formula for variance is
[tex]\sigma^2=\dfrac{\sum (x_i-\overline{x})^2}{n}[/tex] ...(i)
Using (i), we get
[tex]\sigma_A^2=\dfrac{\sum (x_i-\overline{x}_A)^2}{n_A}[/tex]
[tex](3)^2=\dfrac{\sum (x_i-\overline{x}_A)^2}{6}[/tex]
[tex]9=\dfrac{\sum (x_i-\overline{x}_A)^2}{6}[/tex]
[tex]54=\sum (x_i-\overline{x}_A)^2[/tex]
Similarly,
[tex]\sigma_B^2=\dfrac{\sum (x_i-\overline{x}_B)^2}{n_B}[/tex]
[tex](5)^2=\dfrac{\sum (x_i-\overline{x}_B)^2}{4}[/tex]
[tex]25=\dfrac{\sum (x_i-\overline{x}_B)^2}{4}[/tex]
[tex]100=\sum (x_i-\overline{x}_B)^2[/tex]
Now, after combining both sets, we get
[tex]\sigma^2=\dfrac{\sum (x_i-\overline{x}_A)^2+\sum (x_i-\overline{x}_B)^2}{n_A+n_B}[/tex]
[tex]\sigma^2=\dfrac{54+100}{6+4}[/tex]
[tex]\sigma^2=\dfrac{154}{10}[/tex]
[tex]\sigma^2=15.4[/tex]
Therefore, the variance of combined set is 15.4.

I need help on a slope problem to fine the slope of the line
Answer:
Okay what's the problem?
Step-by-step explanation:
Answer:
if you are given two points, use the equation y2-y1 / x2-x1
if you are given a graph, use rise/run
Step-by-step explanation:
if you have two points, like (4,5) and (6,9), take the second numbers of both pairs (the ys) and subtract them from each other (usually 2nd y minus 1st y), so with these points I would do 9-5
then subtract the first numbers of both pairs (the xs) from each other too (just like the ys: 2nd x minus 1st x), so with these points I would do 6-4
now you have y=9-5 which is 4
and x=6-4 which is 2
now you put 4/2 and simplify it to get 2
so your slope with these points is 2
if you want to find slope on a graph, look at where the line crosses the x/y axis lines, the points where they meet, and look at the distance between each point that it crosses
to find the slope put the rise (vertical change in y between each point) over the run (horizontal change in x between each point) in a fraction like this
rise/run
simplify that and you have your slope
