Answer:
The answer is 62
Step-by-step explanation:
the ratio given can be written as [tex]\frac{20}{11}[/tex].
first, we need to solve for how many boys received if the girls received 40.
let's write a new ratio to show this.
[tex]\frac{20}{11} = \frac{40}{x}[/tex]
notice how i was able to equal them to each other. this is because they represent the same rate.
to solve for x, cross multiply.
[tex]20x= 440\\[/tex]
now solve.
[tex]x=22[/tex]
the 22 represents how many boys will receive if the girls receive 40.
the question is asking how many will be given out all together. this implies that we should add 40 and 22.
[tex]40+22= 62[/tex]
62 pickle pop chips were given out.
hope this helps!

Jesse is saving the money he earns in his piggybank. He had already earned
$60 from previous work. He charges $15 to mow one lawn. After mowing 4
lawns, how much total money will he have in his piggybank?
Answer:
Jesse will have $120.
Step-by-step explanation:
First you need to set up your equation. We know Jesse has $60 already and that he charges $15 per lawn. Your equation will look something like this:
15x+60=?
Then you plug in the 4 lawns he did:
15(4)+60=
Then you solve and get 120! :)
PS Parenthesis mean you are multiplying. Same thing as saying
15 x 4 + 60= 120

I looked up how to do this, but I just dont understand how the internet explains it, I need a step by step simple explanation on how to do it.
Answer:
0
Step-by-step explanation:
To solve this without L'Hopital's rule, you need to use this identity:
lim(x→0) (sin x / x) = 1
lim(x→0) (sin²x / x)
lim(x→0) (sin x / x) (sin x)
lim(x→0) (sin x / x) · lim(x→0) (sin x)
1 · 0
0
Alternatively, since plugging in x=0 gets 0/0, we can use L'Hopital's rule. Replace the numerator and denominator with their derivatives.
lim(x→0) (sin²x / x)
lim(x→0) (2 sin x cos x / 1)
0

4x+8=7.2+5x solve for x
Answer:
[tex]\boxed {x = 0.8}[/tex]
Step-by-step explanation:
Solve for the value of [tex]x[/tex]:
[tex]4x + 8 = 7.2 + 5x[/tex]
-Take [tex]5x[/tex] and subtract it from [tex]4x[/tex]:
[tex]4x + 8 - 5x = 7.2 + 5x - 5x[/tex]
[tex]-x + 8 = 7.2[/tex]
-Subtract [tex]8[/tex] to both sides:
[tex]-x + 8 - 8 = 7.2 - 8[/tex]
[tex]-x = -0.8[/tex]
-Divide both sides by [tex]-1[/tex]:
[tex]\frac{-x}{-1} = \frac{-0.8}{-1}[/tex]
[tex]\boxed {x = 0.8}[/tex]
So, the value of [tex]x[/tex] is [tex]0.8[/tex].
The solution of the given expression is x = 0.8.
We are given that;
The expression 4x+8=7.2+5x
Now,
Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.
The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.
To solve for x, we can use the following steps:
- Subtract 4x from both sides: 4x + 8 = 7.2 + 5x - 4x - 4x
- Simplify: 8 = 7.2 + x
- Subtract 7.2 from both sides: 8 - 7.2 = 7.2 + x - 7.2
- Simplify: 0.8 = x
Therefore, by expression the answer will be x = 0.8.

Answer: y=-1/4x+3
Step-by-step explanation:
==================================================
Explanation:
y = mx+b is the general form of slope intercept equations
m is the slope, b is the y intercept
The y intercept is where the graph crosses the y axis. In this case it is at (0,3) so b = 3 is the y intercept
--------------------
The slope can be found through using the slope formula
m = (y2-y1)/(x2-x1)
m = (2-3)/(4-0)
m = -1/4
Or you could note that to go from (0,3) to (4,2) we must go down 1 and over to the right 4.
slope = -1/4 = rise/run
rise = -1 means we go down 1
run = 4 means we move to the right 4
--------------------
Since m = -1/4 and b = 3, we go from y = mx+b to y = (-1/4)x+3
Carly wants to buy some fish to keep in her room. At a local pet store customers can pay
$12.50 for a fish tank and $0.20 for each fish they purchase.
a. What is the slope or rate of change in the situation described? Explain.
Answer:
12.50
Step-by-step explanation:
Im not completely sure on this but the answer is 12.50 because it states that the price for a fish tank is $12.50. So im pretty sure that the intercept is that.
The Slope here is $0.20 which represent cost of each fish.
What is Rate of Change?A rate of change is a rate that describes how one quantity changes in relation to another quantity.
Given that, Carly wants to buy some fish to keep in her room. At a local pet store, customers can pay $12.50 for a fish tank and $0.20 for each fish she purchased,
Let total cost be C, and total number of fish be n
According to question,
C = 12.50 + 0.20n
Hence, the slope 0.20 represents the change in total cost as the number of purchase of fish changes.

Lin rode her bike 2 miles in 8 minutes. How many miles did she go in 4
minutes?
Answer:
1 mile: 4 minutes
Step-by-step explanation:
This problem can be expressed with a simple ratio: 2:8
Now, thankfully the numbers are even so we just need to simplify the ratio to get our answer. Ratios work like fractions in that manner. So we just need to divide both sides by 2 to get the _:4 result.
This gives us a ratio of 1:4. Therefore, Lin travelled 1 mile in 4 minutes.

f(x) = -x2 + 10x - 17 a. Axis of Symmetry: b. Vertex: (Max, Min) c. Domain: d. Range:
Answer:
Below in bold.
Step-by-step explanation:
f(x) = -x^2 + 10x - 17
Convert to vertex form by:
f(x) = -(x^2 - 10x) - 17
= - [(x - 5)^2 - 25] - 17
= -(x - 5)^2 + 25 - 17
= -(x - 5)^2 + 8,
a. So axis of symmetry is x = 5.
b. Vertex is (5, 8) Max.
c. Domain is All real x.
d. Range is (-∞, 8].
