Darcia made a snack mix using the following recipe.
1 ¼ cups granola, ¾ cup peanuts, ½ cup raisins, ¼ cup chocolate chips. If she used 3 cups of granola and wanted to keep the ingredients proportional, how much would she use of each of the other ingredients. Write your answer as a fraction in simplest form. Use / for the fraction bar.
cup(s) peanuts
cup(s) raisins
cup(s) chocolate chips
Answer:
1 4/5 = peanuts
1 1/5 = raisins
3/5 = chocolate chips
Step-by-step explanation:
3 ÷ 1 1/4 = 2 2/5
2 2/5 × 3/4 = 1 4/5
2 2/5 × 1/2 = 1 1/5
2 2/5 × 1/4 = 3/5
To keep proportions with 3 cups of granola, Darcia would need 1 ½ cups of peanuts, 1 ¼ cups of raisins, and 3/5 cup of chocolate chips in her snack mix.
Explanation:Darcia has increased her granola measurement to 3 cups, which is 2.4 times more than the original 1 ¼ cups used in the snack mix recipe (since 3 ÷ 1.25 equals 2.4). To keep the other ingredients proportional to the new quantity, we need to multiply their original amounts by the same factor of 2.4
Therefore, if she used 3 cups of granola, she would use 1 ½ cups of peanuts, 1 ¼ cups of raisins, and 3/5 cup of chocolate chips to maintain the proportions in her snack mix.
An initial population of 2 bunnies each has 6 babies per month. Using x for months and y for the number of bunnies, write the equation that models this situation.
Answer:
x = 3y
Step-by-step explanation:
In this question, we are asked to model an equation that clearly mimics what we have in the question using certain type of variables.
Now initially, we are told that we have 2 bunnies having 6 babies. what does this tell us?
Looking at this, we can see that the number of babies is exactly 3 times the number of bunnies. More like saying 3 times the number of bunnies equal the number of babies.
so leveraging in this finding and applying the variable, we can say each of the 2 bunnies has 3 babies per month.
Mathematically, this is same as x bunnies = 3y babies per month

Suppose the number of bacteria in a certain population increases according to a continuous exponential growth model. a sample of 2200 bacteria selected from the population reached the size 2300 bacteria in one and a half hours. Find the hourly growth rate parameter.
The hourly growth rate is 2%
An exponential growth is in the form:
y = abˣ;
where y, x are variables, a is the initial value of y and b > 1
Let y represent the number of bacteria after x hours.
There was initially 2200 bacteria, hence a = 2200. The equation becomes:
[tex]y=2200(b)^x\\\\\\After\ 1.5\ hours,y=2300:\\\\\\2300=2200(b)^{1.5}\\\\\\b^{1.5}=1.045\\\\1.5lnb=ln(1.045)\\\\ln(b)=0.0296\\\\b=1.02[/tex]

Write a quadratic function f whose zeros are 4 and -5
Answer:
x^2+x-20
Step-by-step explanation:
x = 4
x - 4 = 0
x = -5
x + 5 = -5
(x + 5)(x - 4)
x^2+x-20
The quadratic function with zeros 4 and -5 is f(x) = x² + x - 20.
To write a quadratic function f(x) whose zeros are 4 and -5, we can use the fact that the zeros of a quadratic function correspond to the values of x that make the function equal to zero.
A quadratic function can be represented in the form:
f(x) = a(x - r1)(x - r2)
where r1 and r2 are the zeros of the function.
Given zeros are 4 and -5. Substituting these into the formula, we get:
f(x) = a(x - 4)(x + 5)
Expanding this, we obtain:
f(x) = a(x² + x - 20)
To simplify, we can choose a value for a, usually 1 for simplicity:
f(x) = x² + x - 20
This is the quadratic function with zeros at 4 and -5.

Company Mailing Of a company's mailings 1.5% are returned because of incorrect or incomplete addresses. In a mailing of 200 pieces, find the probability that none will be returned
Answer:
0.0487 = 4.87%
Step-by-step explanation:
The probability of one mail being returned is 1.5% = 0.015, so the probability of the mail not being returned is 1 - 0.015 = 0.985. If we want 0 mails returned from a total of 200 mails, we have 0 mails returned (probabilitity of 0.015) and 200 mails not returned (probability of 0.985), then the final probability is calculated as follows:
Probability = (0.985)^200 * (0.015)^0 = 0.0487 = 4.87%
To find the probability that none of the 200 mailings will be returned because of incorrect or incomplete addresses, we can calculate the probability of an individual mailing not being returned and multiply it by itself 200 times.
Explanation:To find the probability that none of the 200 mailings will be returned, we need to calculate the probability that each individual mailing is not returned. Given that 1.5% of mailings are returned, the probability of an individual mailing not being returned is 1 - 0.015 = 0.985. We can then find the probability that none of the mailings are returned by multiplying this probability by itself 200 times.
P(no mailings returned) = (0.985)200

can 5ft 9ft 14ft make a triangle?
Answer:
Any dimensions can make a triangle, however
this does not make a right angled triangle.
Step-by-step explanation:
Determine the length of the hypotenuse of a right angle triangle with side lengths 5ft and 9ft by using the formula:
[tex]a^2+b^2=c^2\\[/tex]
[tex]\sqrt{a^2+b^2} = c[/tex]
[tex]c=10.29[/tex]
This is not equal to 14ft.
Answer: No, those measurements cannot make a triangle
Why not? Because of the fact that the first two sides (5 and 9) add to 5+9 = 14, which is exactly as long as the third side. I recommend you using a ruler to measure out 5 inches, 9 inches and 14 inches. Mark all three as separate segments on a piece of paper. Then cut out those segments to form strips of paper with the given lengths. Then try to form a triangle. You'll find that it is impossible since the smaller segments combine perfectly to get the longest segment. Instead of a triangle, you'll only have a line segment forming.
As a rule, when you add any two sides of a triangle, they must add to something larger than the third side. The rule more formally is
For any triangle with sides a,b,c, the following three inequalities must hold true

Payne's employers pays 80 percent of the total cost. Her contribution is deducted from her paycheck. What is Payne's annual contribution?
Final answer:
To calculate Payne's annual contribution, multiply the annual premium by 20% and subtract that amount from the annual premium.
Explanation:
To calculate Payne's annual contribution, we need to determine 20% of the total cost of the health insurance premium and then subtract that amount from the annual premium.
Step 1: Find 20% of $6,486. Multiply $6,486 by 0.2 to get $1,297.20.
Step 2: Subtract the 20% contribution from the annual premium. $6,486 - $1,297.20 = $5,188.80.
Payne's annual contribution is $5,188.80.
A support wire is tied diagonally from the middle of a tree to a stake on the ground. The length of the wire is 10 ft and the angle of
elevation from the stake is 55". Approximately how high on the tree is the connection point of the wire?
Answer:
8.2 ft
.Step-by-step explanation:
Sketch this situation. Label the 55° angle. The adjacent side is the distance from the stake to the bottom center of the tree. The opposite side is the distance from the ground to the connection point of the wire on the tree. The wire length represents the hypotenuse of this triangle. We want to find the length of the side opposite the 55° angle. Thus, we write
sin 55° = (opposite side)/(hypotenuse), or
(hypotenuse)(sin 55°) = (10 ft)(0.819) = 8.2 ft
Using trigonometry and the sine function, we can calculate the height of the tree as 10 ft * sin(55), which equals approximately 8.19 ft.
Explanation:This problem can be solved using trigonometry, specifically the sine function. In a right triangle, the sine of an angle is defined as the length of the opposite side divided by the length of the hypotenuse. In this case, the tree forms the opposite side of our triangle, the support wire forms the hypotenuse and the angle of elevation is 55 degrees.
To express this mathematically, we can write: sin(55) = height / 10 ft. Solving this equation for height gives us: height = 10 ft * sin(55). Using a calculator, we find that sin(55) is approximately 0.81915, so the height is around 8.19 ft. Therefore, the connection point of the wire to the tree is at approximately 8.19 ft high.
