Answer:
a) 40 euros
b) 416 pages
c) 25%
Step-by-step explanation:
This question can be translated to:
Maria bought a book, discounted by 15%, at the price of 34 euros. After reading 1/4 of the pages of the book. She reads 2/3 of the remaining pages and at this point, she has 104 pages left to read. Determine:
a) The price of the book before the discount
b) The total number of pages in the book
c) The percentage that represents the number of pages that Maria has left to read out of the total number of pages.
I will answer in English.
a) If P is the price of the book, with a discount of the 15% the price will be:
P' = P - P*(15%/100%) = P - P*0.15 = P*0.85
and P' = 34 eur
34 eur = P*0.85
34 eur/0.85 = 40 eur = P
The original price was 40 euros.
b) Now suppose that the book has N pages.
First, she reads 1/4 of the pages, then we have:
N - (1/4)*N = (3/4)*N pages left.
Then she reads (2/3) of the remaining (3/4)*N pages.
Then there are:
(3/4)*N - (2/3)*(3/4)*N = (1/3)*(3/4)*N = (1/4)*N
And we know that at this point, there are 104 pages left, then:
104 = (1/4)*N
104*4 = N = 416
c) The total number of pages is 416, this is the 100%
there are 104 pages left in the book, this will represent X%, and we want to find the value of X.
then:
416 = 100%
104 = X%
Let's take the quotient of those two equations:
(416)/(104) = (100%/X%)
Now let's isolate X%.
X% = (104/416)*100% = 0.25*100% = 25%
The ratio of boys to girls in a class is 3:4. There are 35 students in the class. How many students are boys?
Answer:
15 boys and 20 girls
Step-by-step explanation:
1. Since we cant simplify 3:4 we will leave it just like that.
2. 3x+4x=35
3. We add them both to give us 7x=35
4. We divide by 7 to get x by itself which results in 35/7=5.
x=5
5. Now we found x we can create 2 seperate soulutions:
3(5)=
and 4(5)=
Therefore there are 15 boys and 20 girls in the class. This makes sense because 15/20 reduced is 3 over 4.
can anyone help me please?

Even though they have two sides that are identical in length, the third side could be any number, based on the angles of the triangle. Since we do not know the angles, there is no way of knowing the length of the third side.
Answer:
A,yes they are congruent triangles because they have same shapes and also same numbers
Step-by-step explanation:
Pablo has completed 44 deliveries so far this week. He needs to make 55 deliveries for the week. What
percentage of his deliveries has Pablo completed?
Answer:
80%Step-by-step explanation:
step one:

the formula is
=completed/total*100
=44/55*100
=0.8*100
=80%
Hence Pablo has completed 80% of the deliveries so far

Your team is in charge of games at the Amusement Park. One of the games involves a robotic arm that randomly grabs a stuffed animal out of a large bin. You need to set up the game so that the probability of a customer’s grabbing a teddy bear is exactly 1/2
a. how would you set up the bin? Explain.
B. What if you returned to check on the bin and found that there are 4 teddy bears left and 12 other animals? What could you add to or remove from the bin to return the probability of selecting a teddy bear to 1/2?
Answer:
a. I would put 20 stuffed animals in the bin, out of which 10 would be teddy bears.
So that the probability is 10/20 = 1/2
b. I could remove 8 other animals from 12 to have 4. So that the total number of stuffed animals is 8. 4/8 = 1/2
Step-by-step explanation:
a. Probability =
number of required outcomes / number of possible outcomes
If in the bin there are 10 teddy bears out of 20 stuffed animals,
Then the probability of picking a teddy bear = 10/20 = 1/2.
b. If on returning, there are 4 teddy bears and 12 other animals, I could simply remove 8 of the other animals to have 4 other animals and a total of 8 stuffed animals.
Probability = 4/8 = 1/2

the first photo is number one, and the second photo is number two :)
Answer:
It's the third one down for both of them.
Step-by-step explanation:
1. first count the spaces from each intersection, starting with down. #1 has a slope of 2/3. Since it's leaning to the left, it's a negative. The only one with -2/3 is the third option down.
2. Again, look at the slope. this one is 2/1 (or just 2), and is leaning to the left, so is negative. Since there are multiple with -2 as the slope, we then look at the y-intercept. It's -1. The only answer that lines up perfectly with what we have is the third one down.
ten Susan works at the local ice cream shop with her friend Tara. Susan is a shift supervisor and is paid $9.50 an hour. The owner of the shop decided to give Susan a bonus of $25 in her upcoming check to say thanks for all of her hard work. Which function shows Susan's salary (S), if she works h hours during the upcoming week?
1. S(h) = 9.50h + 25
2 S(h) = 9.50h - 25
3. S(h) = 25h + 9.25
4. S(h) = 9.50 + 25
Answer:
1.
Step-by-step explanation:
She works 9.50 hourly = 9.50h
She gets a bonus of 25 dollars so +25
Final answer= 9.50h + 25

plzz help mee
Answer:
a) Write a let statement below to define your variable(s):
Let the number of fishes Ms. Montesinos has be represented by = f
b) Set up an equation using the variable you defined in (a):
The equation is :
3f - 2 = 13
c) Solve your equation & Check. How many fish does Ms. Montesinos have?
Ms. Montesinos has 5 fishes
Step-by-step explanation:
Ms. Cruz has a tank with 11 fish. After buying two more, she has 2 less than triple the amount of fish Ms. Montesinos has. How many fish does Ms. Montesinos have in her tank?
a) Write a let statement below to define your variable(s):
Let the number of fishes Ms. Montesinos has be represented by = f
b) Set up an equation using the variable you defined in (a):
We are told in the question:
Ms. Cruz has a tank with 11 fish. After buying two more, she has 2 less than triple the amount of fish Ms. Montesinos has.
Therefore,
3× f - 2 = 11 + 2
The equation is :
3f - 2 = 13
c) Solve your equation & Check. How many fish does Ms. Montesinos have?
Solving the above equation:
3f - 2 = 13
3f = 13 + 2
3f = 15
Divide both sides by 3
3f/3 = 15/3
f = 5
Hence, Ms. Montesinos has 5 fishes

∆GHI is an isosceles triangle with a vertex angle H If the m∠H=80°, then find the m∠I.
Answer:
m∠I = 50 degrees
Step-by-step explanation:
Mathematically, the base angles of an isosceles triangle are equal
So in this case, since H is a vertex;
m∠I + m∠H + m∠G = 180
m∠I = m∠G = x
2x + 80 = 180
2x = 180-80
2x = 100
x = 100/2
x = 50

Step-by-step explanation:
[tex]2x+7-6x=23[/tex]
[tex]-4x+7=23[/tex]
[tex]-4x=16[/tex]
[tex]x=-4[/tex]
Answer:
x=-4
Step-by-step explanation:
2x+7−6x=23
Step 1: Simplify both sides of the equation.
2x+7−6x=23
2x+7+−6x=23
(2x+−6x)+(7)=23(Combine Like Terms)
−4x+7=23
−4x+7=23
Step 2: Subtract 7 from both sides.
−4x+7−7=23−7
−4x=16
Step 3: Divide both sides by -4.
−4x
−4
=
