Sheyna has less than 180 minutes to decorate 60 cookies for the bake sale. How long can she spend decorating each cookie to stay within her time limit? (a) Write and solve an inequality.
Answer:
m < 3
Step-by-step explanation:
Cookies to decorate = 60
Time < 180 minutes
The inequality
60m < 180
Where,
m = number of minutes
60m < 180
m < 180/60
m < 3
Less than 3 minutes decorating each cookie
A basket of snacks contains 8 packs of oreos, 2 bags of chips, 6 packs of gummies, and 4 granola bars. Bill randomly choses 2 snacks. What is the probability a granola bar is chosen one choice after the other without replacing the first bar? {PLZZZZ HELP}
Answer:
There is a 3/95 probability that a granola bar is chosen one choice after the other without replacement.
Step-by-step explanation:
The probability of choosing a granola bar without replacing the first bar is 4/20, or 1/5. 4 represents the number of granola bars, and 20 represents the total snacks. Then there are 19 snacks and 3 granola bars which represents the 3/19 chance of getting a granola bar the second time without replacing it.
To find the probability of both of those events happening, multiply them.
(1/5) * (3/19) = 3/95.

javier bought a microwave for $105. the cost was 30% off the orginal price. what was the price of the microwave before the sale? Step by Step
Answer: price was $150
Step-by-step explanation: original price was x. When discount is 30%
Price is (100-30)% = 70 % from the original. 70% = 0.70
So we have an equation 0.7x = 105. And x= 105/0.7= 150
Eric goes to town with £15. He spends £8.50 on a new scarf.
He meets his nan who gives him £20 and tells him to take £10 of it home for his sister
Eric then sees a jumper he likes which costs £18.
If Eric buys the jumper, will he still have £10 to give it to his sister?
Show how you worked out your answer.
Answer: No he would have 8.5$
Step-by-step explanation:
15 - 8.50 = 6.50$ + 20$ = 8.5 so no he would be 1.5$ short
If Eric buys the jumper, he will not have £10 left to give to his sister.
To determine if Eric will still have £10 to give to his sister after buying the jumper, we need to calculate his remaining balance.
Initial amount Eric has = £15
Cost of the scarf = £8.50
Amount received from his nan = £20
Cost of the jumper = £18
Amount to give to his sister = £10
First, let's calculate Eric's remaining balance after buying the scarf:
Remaining balance = Initial amount - Cost of the scarf
Remaining balance = £15 - £8.50
Remaining balance = £6.50
Next, let's calculate Eric's balance after receiving money from his nan:
Total balance = Remaining balance + Amount received from nan
Total balance = £6.50 + £20
Total balance = £26.50
Now, let's check if Eric can still afford to buy the jumper:
If Eric buys the jumper:
New balance = Total balance - Cost of the jumper
New balance = £26.50 - £18
New balance = £8.50
The new balance after buying the jumper is £8.50. As we can see, this amount is less than the £10 Eric needs to give to his sister.
Therefore, if Eric buys the jumper, he will not have £10 left to give to his sister.

A, B, and C are polynomials, where A = n, B = 2n + 6, and C = n2 – 1. What is AB – C in simplest form?
–n2 + 3n + 5
n2 + 6n + 1
2n2 + 6n – 1
3n2 + 5
Answer:
n^2 + 6n + 1
Step-by-step explanation:
Firstly, we have to evaluate AB
What we have to do is to multiply A and B
We have this as;
n(2n + 6) = 2n^2 + 6n
Now, we have to subtract the value of C from here and that is;
(2n^2 + 6n) - (n^2 - 1)
2n^2 + 6n - n^2 + 1
= 2n^2 -n^2 + 6n + 1
= n^2 + 6n + 1

An electronics store sold 4% of the computers that were on sale.
If only 12 computers were sold, how many computers were not sold?
Answer:
288
Step-by-step explanation:
We can use a proportion to solve this problem:
4 : 100 = 12 : x
x = (12 x 100)/4 = 300 (total computers)
300 - 12 = 288

Using this information, each student can prepare an infinite number of parallelograms
Step-by-step explanation:
The given parameters of the parallelogram Emily asks the students to bring are;
The measure of one of the angles of the parallelogram = 50°
The length of of one side of the parallelogram = 10 cm
The shapes which the parallelogram must not be are; rhombus, rectangle, or square
Using the given information, therefore, the number of different parallelograms the students can prepare is given as follows;
The number of different lengths of the other side of the parallelogram = Infinity - 1 = Infinity
Therefore, the number of different parallelograms the students can prepare is an infinite number of parallelograms

which of the following is a difference of cubes?
a. 3x^9-64y^3
b. 15x^21-64y^3
c. 27x^15-9y^3
d. x^6+27y^9
Answer:
D: x^(6) + 27y^(9)
Step-by-step explanation:
A) 3x^(9) - 64y^(3)
The first term is raised to the power of 9 and has a coefficient which cannot also be expressed as a cube while the second term is raised to the power of 3 but has a coefficient that can be expressed as a cube. Thus the entire equation cannot be simplified to cubes as the first term cannot be expressed a cube.
B) 15x^(21) - 64y^(3)
Similar to the reason given in A above, the first term cannot be expressed as a cube.
C) 27x^(15) - 9y^(3)
In this one, the first term can be expressed as a cube while the second one cannot be expressed as a cube because 9 cannot be expressed as a cube.
D) x^(6) + 27y^(9)
This can be expressed as;
(x²)³ - (-3y³)³
This is therefore a difference of cubes

Which inequality describes the relationship between points A and B on the number line?
Answer:
B > A
Step-by-step explanation:
B and A are both in between 0 and 1 on a number line.
On a number line, the further right you go, the higher numerical values get, and the further left - vice versa.
Anyhow, B is further to the right, as well as closer to 1 than A is, so we can assume that B is the greater number.
