Step-by-step explanation:
Step 1: Define
f(x) = 3x + 10
g(x) = x - 2
f(-10) is x = -10
Find g(f(-10))
Step 2: Solve:
Find f(-10). Substitute: f(-10) = 3(-10) + 10Multiply: f(-10) = -30 + 10Add: f(-10) = -20Substitute: g(-20) = -20 - 2Subtract: g(-20) = -22In a survey tasting lemonade, one fifth of the people surveyed were under 25 years old. If 65 people were under 25, how many people were surveyed.
Ann, Ben, and Cindy were eating strawberries. The ratio of the numbers of berries they ate is 5:5:7. If Cindy ate 30 strawberries less than Ann and Ben together, what is the total number of strawberries the three of them ate?
Answer:
Answer:
170
Step-by-step explanation:
Ann, Ben, and Cindy were eating strawberries.
The ratio of the numbers of berries they ate is 5:5:7.
If Cindy ate 30 strawberries less than Ann and Ben together,
find:
what is the total number of strawberries the three of them ate?
solution:
add the ratios 5 + 5 + 7 = 17
since Cindy ate 30, less than Ann and Ben together so, the equation is
7x = 5x + 5x - 30
7x - 10x = -30
x = 30/3
x = 10
ann 5 x 10 = 50
ben 5 x 10 = 50
cindy 7 x 10 = 70
total = 170

a = 11m, b = 8m and C = 2m for the triangle shown below.
Work out the value of x, giving your answer as an exact surd.
The diagram is not drawn accurately
Answer:
x = [tex]\sqrt{53}[/tex]
Step-by-step explanation:
Using Pythagoras' identity on the upper right triangle.
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides.
Let the third side be d, then
d² + b² = a² , that is
d² + 8² = 11²
d² + 64 = 121 ( subtract 64 from both sides )
d² = 57
Using Pythagoras' identity on the lower right triangle, then
x² + c² = d²
x² + 2² = 57
x² + 4 = 57 ( subtract 4 from both sides )
x² = 53 ( take the square root of both sides )
x = [tex]\sqrt{53}[/tex]

A square has an area of 9yd^2. What is the length of each side?
Answer: The side length is 3 yards.
Step-by-step explanation:
To find the area of a square, you have to square one of it's side lengths since they all share the same length. Since we know the area, and we need to find the side length so we just need to find the square root of the area.
[tex]\sqrt{9}[/tex] = 3
The side length is 3 yards.
The length of each side of a square is, 3 yards.
What is mean by Rectangle?A rectangle is a two dimension figure with 4 sides, 4 corners and 4 right angles. The opposite sides of the rectangle are equal and parallel to each other.
We have to given that;
⇒ An area of square = 9 yards²
Now, We know that;
⇒ Area of square = Side²
Let the side of square = a
So, We get;
⇒ a² = 9
⇒ a = √ 9
⇒ a = 3 yards

A total of 4500 tickets to a concert were sold and the price for each ticket was either $59 or $85. If the
amount collected was $291, 500, how many tickets were sold at each price?
O (35, 10)
O (3500, 1000)
O (1000, 2200)
O (3000, 1500)
Answer:
3500 tickets were sold at $59
1000 tickets were sold at $85
(3500, 1000)
Step-by-step explanation:
x + y = 4500
59x + 85y = 291500
x + y = 4500
x = 4500 - y
59(4500 - y) + 85y = 291500
265500 - 59y + 85y = 291500
265500 + 26y = 291500
26y = 26000
y = 1000
x + y = 4500
x + 1000 = 4500
x = 3500
Check:
x + y = 4500
3500 + 1000 = 4500
4500 = 4500
59x + 85y = 291500
59(3500) + 85(1000) = 291500
206500 + 85000 = 291500
291500 = 291500

Suppose that the grade 7 student expected to sell between 100 and 150 hotdogs. How many packages of 12 wieners and 8 buns should the students buy if they don't want any leftovers ?Justify your answer .How many packages of each should they buy if they expect to sell more than 300 hotdogs.
Assuming that 1 wiener and 1 bun required to sell 1 hotdog.
Given that there are 12 wieners and 8 buns in 1 packet of each.
Let m be the minimum numbers of hotdogs for no leftover wieners or buns.
So, m must be a number which is divisible by both 12 as well as 8.
The smallest number which is the common multiple of both 12 as well as 8 is the highest common factor (H.C.F.) of 12 and 8 which is 24.
So, m=24
At this pint, note that 24 is the minimum number of hotdogs that students can sell with no leftover wieners or buns. For this, they need 2 packets of wieners and 3 packets of buns.
So, 1 m hotdogs required 2 packets of wieners and 3 packets of buns
But, here the number of hotdogs is between 100 and 150.
The next possible number of hotdog wit no leftover wieners or buns is 48 which is 2m, the next will be 3m, and so on.
In fact, any multiple of m will be divisible by 12 as well as 8, so there will not be any leftover wieners or buns.
So, 24n hotdogs require 2n packets of wieners and 3n packets of buns,
where n is a counting number.
Now, find the multiple of 24 in between 100 and 150,
The first multiple is 24x5=120
So, 120 hotdogs require 2x5=10 packets of wieners and 3x5=15 packets of buns
The second multiple is 24x6=144
So, 144 hotdogs require 2x6=12 packets of wieners and 3x6=18 packets of buns
If the students want to sell more than 300 hotdogs:
The minimum number which is multiple of 24 is 24x13=312, the next number is 24x14=336, and so on
For this n=13, 14, 15, ...
So, they need to buy 2n packets of wieners and 3n packets of buns to sell 24n packets of hotdogs for no leftover.
For the minimum number of 312 hot dogs, they need to buy 2x13=26 packets of wieners and 3x12=36 packets of buns.
