Jim is helping his dad cook hamburgers for his family and friends. There are 15 people. Each person wants two hamburgers. Three people want hamburgers with cheese. Two people want hamburgers with mustard. Two people want hamburgers with catsup. The rest want them plain. How many plain hamburgers will Jim and his dad make?
A: 8
B:16
C:21
D:23
The number of people who do not want plain hamburgers is 3+2+2 = 7, so 15-7 = 8 people want plain hamburgers. Each person wants 2 hamburgers, for a total of ...
... B: 16
plain hamburgers.
Jim and his dad will make 23 plain hamburgers.
Explanation:To find the number of plain hamburgers Jim and his dad will make, we need to subtract the number of hamburgers with special toppings from the total number of hamburgers. There are 15 people in total, and each person wants 2 hamburgers, so Jim and his dad need to make 15 x 2 = 30 hamburgers in total.
Out of the 30 hamburgers, 3 people want hamburgers with cheese, 2 people want hamburgers with mustard, and 2 people want hamburgers with catsup. Therefore, the total number of hamburgers with special toppings is 3 + 2 + 2 = 7 hamburgers.
Subtracting the number of hamburgers with special toppings from the total number of hamburgers, we get 30 - 7 = 23 plain hamburgers. Therefore, Jim and his dad will make 23 plain hamburgers.

Students in a class were asked to name their favorite flavor of ice cream. The results are shown in the circle graph. How many times more students prefer cookies and cream than prefer strawberry?
Cookies and Cream: 18%
Strawberry: 2%
Cookie Dough: 35%
Vanilla: 25%
Chocolate Chip: 20%
Answer: 9 times
Step-by-step explanation:
Let the total number students be x.
Then the number of students liked cookies and cream = 18% of x= 0.18 x
The number of strawberry = 2% of x = 0.02 x
Clearly, 0.18 x> 0.02 x
The number of times more students prefer cookies and cream than prefer strawberry =[tex]=\frac{0.18x}{0.02x}=9[/tex]
Hence, The students prefer 9 times cookies and cream than prefer strawberry.

how many shelves will display 2 cars if 8 of the shelves each display 1 car
To determine the number of shelves that will display 2 cars each when 8 shelves display 1 car each, simply divide 8 by 2. The answer is 4 shelves.
To solve this problem, we'll use basic arithmetic. If each of the 8 shelves displays 1 car, then to display 2 cars on a shelf, we would need to combine pairs of shelves. This means we would take the 8 shelves, and divide by 2 cars per shelf to find the number of shelves needed for 2 cars each. So, 8 shelves divided by 2 cars per shelf equals 4 shelves.
Therefore, the answer is that 4 shelves will display 2 cars each if there were originally 8 shelves with 1 car each.
An implicit equation for the plane passing through the point (-1,-4,5) that is perpendicular to the line l(t) = <1+2t,1+t,5+3t> is
Final answer:
The implicit equation of the plane is 2x + y + 3z - 14 = 0, found using the direction vector of the line as the normal vector for the plane and the given point to determine the specific plane equation.
Explanation:
To find an implicit equation for the plane passing through the given point (-1,-4,5) and perpendicular to the given line, we need to determine the direction vector of the line which will also serve as the normal vector to the plane. The equation of the line is given as l(t) = <1+2t, 1+t, 5+3t>, which suggests that the directional vector of the line (and thus the normal vector of the plane) is <2, 1, 3>.
Now, the general equation of a plane in 3D space can be given by Ax + By + Cz + D = 0, where <A, B, C> is the normal vector to the plane. Thus, substituting the normal vector and the given point into this equation will allow us to find the value of D and hence the implicit equation of the plane. In this case, the equation is given by:
2(x + 1) + 1(y + 4) + 3(z - 5) = 0, simplifying this gives:
2x + y + 3z - 14 = 0,
which is the implicit equation of the desired plane.
Final answer:
The implicit equation of the plane passing through the point (-1, -4, 5) and perpendicular to the line ℒ(t) is 2x + y + 3z - 9 = 0.
Explanation:
To find an implicit equation for a plane that is perpendicular to a given line, we first need the direction vector of the line. The line ℒ(t) = <1+2t, 1+t, 5+3t> has a direction vector of <2, 1, 3>, which also serves as the normal vector of the plane. The normal vector (A, B, C) and a point (x0, y0, z0) on the plane can provide an equation via the dot product: A(x - x0) + B(y - y0) + C(z - z0) = 0.
For the given point (-1, -4, 5), the equation becomes 2(x + 1) + 1(y + 4) + 3(z - 5) = 0. Simplifying, we get:
2x + 2 + y + 4 + 3z - 15 = 0
2x + y + 3z - 9 = 0
This is the implicit equation of the plane that passes through the point (-1, -4, 5) and is perpendicular to the given line.
Kira is saving money to buy a bike that costs $133 . She has $42 and will save an additional $7 each week. In how many weeks will she have enough money to buy the bike?
For the past 7 years, George and Sue have deposited $10,000 in a retirement account with a simple interest rate of 4%. They plan to continue to make annual deposits for the next 15 years. Explain how their money will grow over time. Note: You do not need to extend their entire savings for 22 years in your explanation. Focus on the earning for the first several years and explain how their money will grow.
Answer:
George and Sue's money will grow due to both to their contributions and the simple interest that they accrue. Simple interest means that the interest they receive will be applied to the principle, but not the interest that has been accrued. This means that for every $10,000 they put in, they will receive $400 dollars in interest every year, and this number will not change with time.
Right now, they've deposited 10,000 every 7 years for a total of 70,000 dollars. Their annual interest therefore is 400 * 7 = 2800. With every 10,000 dollars they deposit, the yearly interest will grow by $400. This is different from compounding interest, in which annual interest will grow by more than $400 dollars every year since the rate will be applied to principle and all accrued interest.
Step-by-step explanation:
Recall that you can use the built-in functions rem(m,n) or mod(m,n)to find the remainder of the division m/n.
The 'rem(m, n)' and 'mod(m, n)' methods in mathematics provide the remainder of the division operation m / n. When dealing with numbers in exponential form, you divide the base numbers and subtract the exponents to simplify the terms. An understanding of these operations is essential for solving more complex equations.
Explanation:In mathematics, there are two ways to find the remainder of a division operation: rem(m,n) or mod(m,n). These functions take two numbers m and n, and return the remainder when m is divided by n.
For example, in the case of 106 divided by 103, you would first divide the 'base' numbers (10/10) which equals 1, and then subtract the exponents (6-3) which equals 3. So, the result is 103 or 1000. Another example is 4.5 x 109 divided by 103. Here, first you divide 4.5 by 1 (since 10/10 = 1) and then subtract 9-3 equals 6. Therefore, the answer is (4.5) x 106.
