When Ravi brought 3 friends to his house after school, his mother gave them a box of pretzels and a box of crackers. She told them to share the snacks equally among themselves and to give her any that were leftover.
The boys opened the boxes and found a total of 26 pretzels and 35 crackers.
How many pretzels and crackers did the boys give to Ravi's
Answers
Answer:
6 pretzels and 8 crackers
Step-by-step explanation:
Since his mom told him to give her the remaining, 6*4= 24 giving to his mom 2 pretzels and 8*4=32 so he has to give his mom 3 crackers. This way him and his friends have the same amount of snacks.
Hope you find it useful. Good night
Important:
4 friends
Next, we have to share the snacks equally, that means that each person gets the same exact amount of snacks.
Important:
4 friends
same exact amount if snacks for each person
Now, since you are seperating them equally amongst the four friends, we have to divide but you cannot go above the number 26, or 35.
4x7 gives you 28, although 26 is not divisble by 26, its ok to have extra so each child will have 4x6 (24) 6 crackers.
4x8 gives you 32 and you wouldn"t choose 4x6, or 7 because you will either have too many or too little.
So, each child will get 6 pretzels and 8 crackers. It is okay if there are extra snacks.

Answers
Answer:
The graph is shown below.
Step-by-step explanation:
The trigonometric expression is:
[tex]f(x)=sin\ (x)-5[/tex]
The general form is:
[tex]f(x)=a\ \text{sin}\ (bx-c)+d[/tex]
Comparing the two expression we know:
a = 1
b = 1
c = 0
d = -5
Compute the value of amplitude, |a | as follows:
[tex]\text{Amplitude}=|a|=|1|=1[/tex]
Compute the period of the function as follows:
[tex]\text{Period}=\frac{2\pi}{|b|}=\frac{2\pi}{|1|}=2\pi[/tex]
Compute the phase shift as follows:
[tex]\text{Phase Shift }=\frac{c}{b}=\frac{0}{1}=0[/tex]
The vertical shift is:
[tex]\text{Vertical Shift}=d=-5[/tex]

Dan was thinking of a number. Dan adds 10 to it, then doubles it and gets an answer of 56.6. What was the original numbe
Answers
Answer:
[tex]\fbox{\begin{minipage}{5em}A = 18.3\end{minipage}}[/tex]
Step-by-step explanation:
Given:
Dan was thinking of a number.
Dan adds 10 to it, then doubles it and gets an answer of 56.6.
Solve for:
Dan's original number
Step 1: Clarify the problem:
Denote Dan's original number as A
Dan adds 10 to A => 10 + A, then
Dan doubles this sum => 2 x (10 + A), then
Dan gets an answer of 56.6 => 2 x (10 + A) = 56.6
Step 2: Solve for the defined equation:
2 x (10 + A) = 56.6
Let's divide both sides of equation by 2:
2 x (10 + A)/2 = 56.6/2
We simplify both sides after division:
10 + A = 28.3
Let's transfer all numbers to the right side, except A (the sign of 10 is changed from + to -)
A = 28.3 - 10
Let's perform the subtraction to get A:
A = 18.3
Hope this helps!

A grocery store has a discount of 13% off hand soap. At the same time the hand soap manufacturer has a coupon for $2.00 off. Assuming both promotions can be applied at the same time how much more would you pay if you applied the coupon first?
Answers
Answer:
[tex]\$0.26[/tex] has to be paid more if the coupon is applied first
Step-by-step explanation:
Given: A grocery store has a discount of 13% off hand soap. At the same time the hand soap manufacturer has a coupon for $2.00 off.
To find: how much more would be paid if the coupon is applied first
Solution:
Let $ x denotes cost of hand soap
Case 1:
If the discount is given first,
cost of hand soap = [tex]x-\frac{13}{100} x=\$ \frac{87}{100}x[/tex]
If the coupon for $2.00 off is applied,
Final cost of the hand soap = [tex]\$\,(\frac{87}{100}x-2)[/tex]
Case 2:
If the coupon for $2.00 off is applied first,
cost of hand soap = [tex]\$(x-2)[/tex]
If the discount is given then,
final cost of the hand soap = [tex](x-2)-\frac{13}{100}(x-2)=\frac{87}{100}(x-2)[/tex] = [tex]\frac{87}{100}x-\frac{87}{50}[/tex]
Here,
[tex]\frac{87}{100}x-\frac{87}{50}-\frac{87}{100}x+2=\frac{13}{50}=\$0.26[/tex]
So, [tex]\$0.26[/tex] has to be paid more if the coupon is applied first.

Determine the interest earned on a 3 and 1/4 year investment of $2880 at a rate of 4.5%
Answers
Answer:
The interest earned is $421.2.
Step-by-step explanation:
This is a simple interest problem.
The simple interest formula is given by:
[tex]E = P*I*t[/tex]
In which E is the amount of interest earned, P is the principal(the initial amount of money), I is the interest rate(yearly, as a decimal) and t is the time.
In this question:
[tex]P = 2880, I = 0.045, t = 3 + \frac{1}{4} = 3.25[/tex]
So
[tex]E = P*I*t[/tex]
[tex]E = 2880*0.045*3.25[/tex]
[tex]E = 421.2[/tex]
The interest earned is $421.2.

An economist wants to estimate the mean per capita income (in thousands of dollars) for a major city in Texas. Suppose that the mean income is found to be $18.5 for a random sample of 2253 people. Assume the population standard deviation is known to be $6.1. Construct the 98% confidence interval for the mean per capita income in thousands of dollars. Round your answers to one decimal place.
Answers
Answer:
= ( $18.2, $18.8)
Therefore, the 98% confidence interval (a,b) = ( $18.2, $18.8)
Step-by-step explanation:
Confidence interval can be defined as a range of values so defined that there is a specified probability that the value of a parameter lies within it.
The confidence interval of a statistical data can be written as.
x+/-zr/√n
Given that;
Mean x = $18.50
Standard deviation r = $6.10
Number of samples n = 2253
Confidence interval = 98%
z(at 98% confidence) = 2.33
Substituting the values we have;
$18.5+/-2.33($6.1/√2253 )
$18.5+/-2.33($0.128513644290)
$18.5+/-$0.299436791196
$18.5+/-$0.3
= ( $18.2, $18.8)
Therefore at 98% confidence interval (a,b) = ( $18.2, $18.8)

1. Mrs. Verner's class has
a total of 15 students. If 8
of them are girls, what
percentage are boys?
Answers
Answer:
46.7%
Step-by-step explanation:
Given:
Total number of students in Mrs. Verner's class = 15
Number of girls = 8
To find: percentage are boys
Solution:
Percentage of boys = ( Number of boys / Total number of students ) × 100
Number of boys = Total number of students - Number of girls = 15 - 8 = 7
So,
Percentage of boys = [tex]\frac{7}{15}[/tex] × 100 = 46.7%
Suppose that the functions u and w are defined as follows.
Answers
Answer:
- 3 and 3
Step-by-step explanation:
To evaluate (u ￮ w)(- 1), evaluate w(- 1) then use this value to evaluate u(x)
w(- 1) = (- 1)² + 2 = 1 + 2 = 3, then
u(3) = - 3

To evaluate (w ￮ u)(- 1), evaluate u(- 1) then use this value to evaluate w(x)
u( - 1) = - (- 1) = 1, then
w(1) = 1² + 2 = 1 + 2 = 3
We have a bag containing 4 yellow, 5 green and 6 orange candies. We draw two candies without replacement.
Find the probability of getting both candies green
Answers
Answer:
9.52% probability of getting both candies green
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
The order in which the candies are selected is not important. They are also selected without replacement. So we use the combinations formula to solve this question.
Combinations formula:
[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
Find the probability of getting both candies green
Desired outcomes:
2 green, from a set of 5. So
[tex]D = C_{5,2} = \frac{5!}{2!3!} = 10[/tex]
Total outcomes:
2 from a set of 4+5+6 = 15. So
[tex]T = C_{15,2} = \frac{15!}{2!13!} = 105[/tex]
Probability:
[tex]p = \frac{D}{T} = \frac{10}{105} = 0.0952[/tex]
9.52% probability of getting both candies green

Answers
Answer:
Bonita's product is too large
Step-by-step explanation:
The two factors in the problem are (5/6) and (5/3). The factor 5/6 is less than 1, ensuring that the product will be less than 5/3.
Bonita's result of 7/3 is more than 5/3, so is too large to be the product.
