Kiara baked 30 oatmeal cookies and 48 chocolate chip cookies to package in plastic containers for her teacher
friends at school
She wants to divide the cookies into identical containers so that each
container has the same number of each kind of cookie.
If she wants each container to have the greatest number of cookies possible, how many plastic containers does she
need?
Answer: 16 containers?
Step-by-step explanation:
Number of oatmeal cookies with Kiara = 30
Number of chocolate chips cookies with Kiara = 48
To find the greatest number of container neded so that there are equal amount of each cookies in each , we have to find the HCF of 30 and 48 .
Factors of 32 = 1 , 2 , 4 , 6 , 8 , 16 and 32
Factors of 48 = 1 , 2 , 3 , 4 , 6 , 8 , 12 , 16 , 24 and 48
Common and highest among these factors = 16
Which means 16 is the HCF of 32 and 48 .
∴ Kiara will need 16 plastic containers .

Hey there!
Given;
ABC is a Right angled triangle.
Taking angle "A" as reference angle, we get;
Perpendicular (p) = BC
hypotenuse (h) = 13cm
Base(b) = 8cm
We know;
[tex] {h}^{2} = {p}^{2} + {b}^{2} [/tex]
[tex]or; \: p(BC) = \sqrt{ {h}^{2} - {b}^{2} } [/tex]
[tex] BC = \sqrt{ {13}^{2} - {8}^{2} } [/tex]
[tex] BC = \sqrt{169 - 64} [/tex]
[tex] BC = \sqrt{105} [/tex]
[tex] BC = 10.246[/tex]
Therefore, BC = 10.246cm.

The length of a rectangle is 11 less than 9 times the width. The perimeter of the rectangle is 18 inches
Length = 7 Width = 2
Step-by-step explanation:
L = Length
W = Width
L=9w-11
2L+2W=18
2(9W-11) + 2W = 18
18W - 22 +2W = 18
20W -22 = 18
20W = 40
W = 2
L = 9(2)-11
L=18-11

LM is a perpendicular bisector of NP The length of LN is 12w +7, and the length of LP is 15w 5. What is the length of LN?
Answer:
[tex]LN = 55[/tex]
Step-by-step explanation:
Given
[tex]LN = 12w + 7[/tex]
[tex]LP = 15w - 5[/tex]
Required
Determine LN
Since LM is a bisector, then we have:
[tex]LP = LN[/tex] (See attachment for illustration)
[tex]15w - 5 = 12w + 7[/tex]
Collect Like Terms
[tex]15w - 12w = 5 +7[/tex]
[tex]3w = 12[/tex]
Solve for w
[tex]w = 12/3[/tex]
[tex]w = 4[/tex]
LN is calculated as thus:
[tex]LN = 12w + 7[/tex]
Substitute 4 for w
[tex]LN = 12 * 4 + 7[/tex]
[tex]LN = 48 + 7[/tex]
[tex]LN = 55[/tex]
Eric is a lifeguard at his community pool. Before working, he likes to swim laps to exercise. Eric started by swimming 12 laps and increases the number of laps he swims by 3 laps each week. - Identify the slope modeled by the linear relationship. Explain what the slope means in context of the problem. - Identify the y-intercept modeled by the linear relationship. Explain what the y-intercept means in context of the problem.
Answer:
Step-by-step explanation:
Eric started by swimming laps = 12
And increases number of laps each week = 3 laps
If Eric spends x week for the swimming, linear equation representing the number of laps 'y' after 'x' weeks will be,
y = 12 + 3x
Slope of the equation when graphed = 3
y - intercept of the equation = 12
Therefore, Slope of the equation represents the increase in laps per week.
And y-intercept represents the number of laps at the starting.
You are running a 10 mile race. You run the first 3 miles in 24.7 minutes. Your goal is to finish the race in less than 1 hour and 20 minutes. What should you average running time (in minutes per mile) be for the remaining miles?
Answer:
Therefore you have to run every mile in ~ 8 minutes.
Step-by-step explanation:
10 miles - 3 miles = 7 miles left.
1 hour 20 minutes - 24.7 minutes= 80 minutes - 24.7 minutes
= 55.3 minutes left
Therefore, you have 55.3 minutes left to run 7 miles. But since you want to finish in LESS than 1 hour and 20 minutes, subtract the .3.
So:
7 miles = 55 minutes
1 mile x minutes
x minutes= 55 x 1 ÷ 7 miles
x minutes = 7.85
x minutes = ~ 8 minutes
Therefore you have to run every mile in ~ 8 minutes.

the equation 3x^2-6x=8 is rewritten in a form of 3(x-p)^2+q=0.
Answer:
[tex]3(x - 1)^2 - 11= 0[/tex]
Step-by-step explanation:
Given
[tex]3x^2 - 6x = 8[/tex]
Required
Rewrite in form of [tex]3(x - p)^2 + q = 0[/tex]
[tex]3x^2 - 6x = 8[/tex]
Subtract 8 from both sides
[tex]3x^2 - 6x - 8 = 8 - 8[/tex]
[tex]3x^2 - 6x - 8 = 0[/tex]
Express -8 as 3 - 11;
So, we have:
[tex]3x^2 - 6x + 3 - 11= 0[/tex]
Expand [tex]3x^2 - 6x + 3[/tex]
[tex]3(x^2 - 2x + 1) - 11= 0[/tex]
Factorize the expression in the bracket;
[tex]3(x^2 - x -x + 1) - 11= 0[/tex]
[tex]3(x(x - 1) -1(x - 1)) - 11= 0[/tex]
[tex]3((x - 1)^2) - 11= 0[/tex]
[tex]3(x - 1)^2 - 11= 0[/tex]
By comparison: [tex]3(x - p)^2 + q = 0[/tex]
[tex]p= 1[/tex]
[tex]q = -11[/tex]

What is the scale factor from triangle ABC to triangle PQR?
The scale factor from triangle ABC to triangle PQR is 2/3 or 3/2, depending on the direction of comparison.
To find the scale factor from triangle ABC to triangle PQR, we need to compare the corresponding side lengths of the two triangles.
Side AB corresponds to side PQ, which has a length of 6 units.
Side BC corresponds to side QR, which has a length of 9 units.
Side AC corresponds to side PR, which has a length of 12 units.
So, the scale factor from triangle ABC to triangle PQR can be found by comparing the ratio of corresponding side lengths:
AB/PQ = BC/QR = AC/PR
Using the values we found above, we can write:
|AB/PQ| = 2/3
|BC/QR| = 3/4
|AC/PR| = 4/5
Since all three ratios are equal in magnitude, we can take any one of them to be the scale factor. Therefore, the scale factor from triangle ABC to triangle PQR is 2/3 or 3/2, depending on the direction of comparison.

Answer: 3/4
Step-by-step explanation:
Slope=rise/run
In this case we rise up 3
And we run 4 to the right
Which makes the slope 3/4
Hi ! The answer would be 3/4.
To get this answer, the red line represents the RISE, and the blue line represents the RUN.
Your slope will always have RISE/RUN.
Now, you count how many squares there are in your rise, in this case, 3.
Then, you do the same for your run, which would be 4.
Rise/Run becomes 3/4.
What would determine it to be a negative? Well, if you see charts like these: You'll see that the red is going up, it is a positive slope, while the blue, which is going down, is a negative slope.
For example, if sales at your store increased, your slope would go up (positive), while if the opposite it'd go down (negative).
In this case, it is a positive slope.
Describe how you would solve -2x - 3 < 5
Answer:
x > -4
Step-by-step explanation:
-2x-3<5
+3 +3
-2x<8
/-2 /-2
x>-4
Basically, you subtract -3 from both sides to isolate -2x. Now the equation should be -2x<8. You divide by -2 on both sides to isolate the variable (x) and you should end up with x<-4. You flip the sign because you divided by a negative number. You should end up with x>-4.
Your bank charges you a fixed monthly fee for banking there and a charge for each check you write one month you wrote 23 checks and were charged 16.70 the next month you wrote 18 checks and were charged 15.95 how much is your fixed monthly charge and how much do they charge per check
Answer:
Your fixed monthly charge is $13.25 and the charge per check is $0.15.
Step-by-step explanation:
The formula to calculate the amount the bank charges you would be equal to the fixed monthly fee plus the charge for each check for the number of checks. According to that, if you wrote 23 checks and were charged 16.70, this would be:
x+23y=16.70
Also, if you wrote 18 checks and were charged 15.95, you would have the following equation:
x+18y=15.95
You can use these equations to find the value of x and y:
x+23y=16.70 (1)
x+18y=15.95 (2)
where x is the fixed monthly fee and y is the charge for each check
First, you can solve fo x in (1)
x=16.70-23y (3)
Then, you can (3) in (2):
16.70-23y+18y=15.95
16.70-5y=15.95
16.70-15.95=5y
0.75=5y
y=0.75/5
y=0.15
Finally, you can replace the value of y in (3) to find x:
x=16.70-23(0.15)
x=16.70-3.45
x=13.25
According to this, the answer is that your fixed monthly charge is $13.25 and the charge per check is $0.15.

Which of the following graphs is the solution set of -10 < 3x - 4 < 8?
Answer:
Its the first one . A
Step-by-step explanation:
The solution set for the given inequality is {-1, 0, 1, 2, 3}. Therefore, option A is the correct answer.
What are inequalities?Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.
The given inequality is -10<3x-4<8.
Now, -10<3x-4
Add 4 on both the sides of an inequality, we get
-6<3x
-2<x
Now, 3x-4<8
Add 4 on both the sides of an inequality, we get
3x<12
x<4
-2<x<4
Solution set is {-1, 0, 1, 2, 3}
