If 1/3 = 1/A+1/B where A and B are different whole numb rs, find the value of both A and B.
(working)
Answers
The quickest way in this one was to just start checking while numbers as A until you get one for B, you know both A and B have to be greater than 3 for their inverse to create smaller fractions to add up to 1/3, in this case you would test 4 first giving you 1/3=1/4+1/B then see if B being their common denominator gives the right solution to the equation 1/3=1/4+1/12 Becomes 4/12=3/12+1/12 which does work out

He starts from school, which is at the location indicated by the point on the grid above. He then walks to the library 5 units west. After the library, he goes to the gym, which is 6 units north. From the gym, he goes to his guitar class, which is 3 units west. Which of the following is the location of his guitar class?
Answers
Answer:
So, David's guitar class is located at point (-6,2) on the coordinate grid.
Step-by-step explanation:
David starts from school, which is two units to the right and four units down from the origin. This location is indicated by the point (2,-4).
He walks 5 units west to the library.
So, find the point that is 5 units to the west of point (2,-4). Distances east and west on the grid represent a change in the x-coordinate. Moving 5 units to the west on the grid from point (2,-4) places the new location at point (-3,-4).
He then walks 6 units north to the gym.
So, find the point that is 6 units to the north of point (-3,-4). Distances north and south on the grid represent a change in the y-coordinate. Moving 6 units to the north on the grid from point (-3,-4) places the new location at point (-3,2).
David then walks 3 units west to his guitar class.
So, find the point that is 3 units to the west of point (-3,2). Moving 3 units to the west on the grid from point (-3,2) places the new location at point (-6,2).

How many unique triangles can be drawn with side lengths 12 cm and 16 cm, and a 50° included angle?
A. 0
B. 1
C. 2
D. an infinite number
Answers
1 unique triangle
Step-by-step explanation:
There are several ways to determine if the information given about a triangle produces a unique triangle or not. One option is to provide two side lengths and the angle included between them, this is known as SAS (side-angle-side) congruence, this is not to be confused with SSA (side-side-angle) congruence. Since this is one of the groups of givens that provides a unique triangle, then the number of unique triangles that can be drawn is 1 unique triangle.

Emily can arrange 20 vases of flowers in 6 hours. Find Emily's rate per hour for arranging
flowers.
Answers
Answer:
[tex]3 \frac{1}{3}[/tex] vases per hour
Step-by-step explanation:
To find the unit rate, solve the total amount of vases that Emily arranged divided by the amount of time that Emily took to arrange the vases.
Or, in other words, solve 20 ÷ 6, since Emily arranged 20 vases and it took her 6 hours to complete it.
You can do this by hand or you can do it on a calculator.
After you solved it, you should get [tex]3 \frac{1}{3}[/tex], or 3.33333...
So, Emily's rate is [tex]3 \frac{1}{3}[/tex] vases per hour.

A trapezoidal window is 8 feet tall and has base lengths of 1 foot and 7 feet. What is the area of the window? The area of the window is _____ square feet.
Can you help me do it.
Answers
Answer: 32 ft²
Step-by-step explanation:
The area of a trapezoid is calculable using the formula:
= (a + b)/ 2 * height
Where a and b are the base lengths.
= (1 + 7) / 2 * 8
= 8/2 * 8
= 4 * 8
= 32 ft²

At the fair concession stand, a drink costs $1.50, and a hot dog costs $2.75. If Jacob has $18 to spend on food, how many of each item can he buy?
3 drinks and 7 hot dogs
3 drinks and 5 hot dogs
2 drinks and 7 hot dogs
2 drinks and 5 hot dogs
Answers
Answer:
Answer is D (2 drinks and 5 hotdog's)
Step-by-step explanation: 1st answer is over as it is $19.25 for only the hotdogs. 2nd is $18.50 which is a little over. 3rd one is $22.25. And the forth one is $16.75 which is perfect because he cant buy anything else with the remainder of his money.
You can use trial and error for 3 drinks and 2 drinks and can see how many hot dogs are available for Jacob to buy in $18 budget.
Jacob, with $18 dollars for food, under given conditions, can buy:
Option D: 2 drinks and 5 hot dogs.
How to decide what amount of drinks and hot dogs are obtainable in given $18 budget?This can be modeled by mathematical expression with use of variables, and inequality.
Suppose that you can by [tex]x[/tex] drinks and [tex]y[/tex] hot dogs, then their amount should not exceed $18 and they should try to use that $18 as much as they can.
Since 1 drink costs $1.5 and 1 hot dog costs $2.75, thus,
[tex]1.5x + 2.75y \leq18[/tex]
Using trial and error for 2 and 3 drinks (we could've done fro 5 or 7 hot dogs too)For 2 drinks:
Since x = amount of drinks = 2, thus from the obtained inequality, we have:
[tex]1.5x + 2.75y \leq 18\\1.5 \times 2 + 2.75y \leq 18\\2.75y \leq 18 - 3\\y \leq \dfrac{15}{2.75}\\\\y \leq 5.555...\\y = 5[/tex]
We took y = 5 since it is closest integer less than 5.55... since we cannot buy drink or hot dog in decimal points generally and cannot spend more than $18
Thus, if Jacob buys 2 drinks, then he can by 5 hot dogs at max.
For 3 drinks:
Since drinks' amount increased, then hot dogs amount will have to decrease to keep them together under $18. And since in 2 drinks Jacob could by 5 hot dogs, thus, now he will have to buy less than 5 hot dogs, which are not given in options.
Thus,
Jacob, with $18 dollars for food, under given conditions, can buy:
Option D: 2 drinks and 5 hot dogs.
