Pls someone answer this I will give you a lot of points
Answer:
Part A: 4 3/4
Part B: 1 1/4
Step-by-step explanation:
A: sum of 2 1/2 and 2 1/4 = 2 2/4 + 2 1/4 = 4 3/4
B: 6 can be made to be 5 4/4 because it is 5 + 1
5 4/4 - 4 3/4 = 1 1/4
Dimas is playing a game that uses a number cube. The sides of the cube are labeled from 1 to 6. Dimas wants to roll a 2 or a 3. He rolls the
number cube one time,
What is the probability that he will roll a 2 or a 3?
Who ever answer FIRST I WILL GIVE YOU BRAINIEST ANSWER
Answer:
The probability that he will roll a 2 or a 3
[tex]P((E_{1} UE_{2} ) = \frac{1}{3}[/tex]
Step-by-step explanation:
Step(i);-
Dimas is playing a game that uses a number cube.
The sides of the cube are labelled from 1 to 6
The total number of Exhaustive cases
n(S) = {1,2,3,4,5,6} = 6
Step(ii):-
Let E₁ be the event of roll a '2'
n(E₁) = 1
The probability that Dimas wants to roll a '2'
[tex]P(E_{1} ) = \frac{n(E_{1} )}{n(S)} = \frac{1}{6}[/tex]
Let E₂ be the event of roll a '3'
n(E₂) = 1
The probability that Dimas wants to roll a '3'
[tex]P(E_{2} ) = \frac{n(E_{2} )}{n(S)} = \frac{1}{6}[/tex]
But E₁ and E₂ are mutually exclusive events
P(E₁∩E₂) = 0
Step(iii):-
The probability that he will roll a 2 or a 3
we have P((E₁UE₂) = P(E₁)+P(E₂)
= [tex]= \frac{1}{6} + \frac{1}{6} = \frac{2}{6} = \frac{1}{3}[/tex]
[tex]P((E_{1} UE_{2} ) = \frac{1}{3}[/tex]
please hurry , help please??? find the values of the variables
Answer:
x=60
Step-by-step explanation:
The angles here are alternate interior angles, this means that they are congruent. Congruent means that they are equal to each other, so to solve just set them equal! (Your variable is x so you're solving for that)
[tex]2x=120\\x=60[/tex]

w6+58=-138!! what is x PLEASE
Answer:
the answer is -196 im sorry if i got it wrong
Step-by-step explanation:
Answer:
w = ~ - 32.7
Step-by-step explanation:
w6 + 58 = -138
Subtract 58 on both sides
w6 + 58 - 58 = -138 - 58
w6 = -196
Divide by 6 on both sides to isolate the variable
w6/6 = -196/6
w = - 32.66666666666667
w = ~ - 32.7
Hope this helped!

Answer:
a. $14.99k + $24+ $25 = x
b. $14.99(3) + $24+ $25 = x
$44.97 + $24 + $25 = $93.97
Step-by-step explanation:
Answer:
i) C= $14.99 k + $24
ii) $93.97
Step-by-step explanation:
Let the number of models be represented by -----------k
Let the amount spent on books to be--------$24
The equation that represent amount spent in the mall is given as;
C= $14.99 k + $24 ---------------where ;
C= the equation for the total amount spent in the mall
k = the number of plane models
ii)
Using the equation : C= $14.99 k + $24 and if k = 3 and the amount spent on the store is $25 then ;
C= $14.99 * 3 + $24 = $44.97 + $24 = $68.97
C+ 25 = $68.97 + 25 =$93.97

Find the values of x and y.
Answer:
x = 15; y = 21
Step-by-step explanation:
The vertical angles have the same measure.
The sum of the measures of the angles of a triangle is 180 deg.
Left triangle:
4y - 18 + y + 14 + 6x - 11 = 180 Equation 1
Right triangle:
6x - 11 + 81 + x + 5 = 180 Equation 2
Simplify Equation 1.
4y - 18 + y + 14 + 6x - 11 = 180
6x + 5y = 195 Equation 3
Simplify Equation 2.
6x - 11 + 81 + x + 5 = 180
7x = 105
Solve last equation for x.
7x/7 = 105/7
x = 15
Substitute 15 for x in Equation 3 and solve for y.
6x + 5y = 195
6(15) + 5y = 195
90 + 5y = 195
5y = 105
y = 21
Answer: x = 15; y = 21

A ship must have 1 lifeboat for every 12 passengers, plus one lifeboat for
the crew and one backup lifeboat. Which equation shows the
relationship between the number of passengers, p, and the number of
lifeboats needed, I?
Select one
1) I= 2 + 1/2
2) I= 2p + 10
3) I= 12p
4)I=2+ p/12
===========================================
Explanation:
p = number of passengers
L = number of lifeboats
Since we're grouping the passengers in groups of 12, this strongly implies we'll be dividing two values. Specifically we have p divided by 12 to represent the number of boats we will need just for the passengers.
For example, let's say p = 36. This means we have 36 passengers. That would mean we need p/12 = 36/12 = 3 boats for those 36 passengers. This excludes the crew and backup boat. Adding those two extra boats leads to the expression 2 + p/12 which is the total number of lifeboats needed.
In the event that p is not a multiple of 12, this leads to p/12 not being a whole number. We could have say p = 50 passengers which means p/12 = 50/12 = 4.167 approximately. We will not round this to 4 because then we'll have passengers without a lifeboat.
We must round 4.167 up to the nearest whole number to get 5. The first four boats take care of 4*12 = 48 passengers, while that 5th boat handles the remaining 50-48 = 2 people. Since 2 people in a boat seems like a really low count, the crew could likely spread the people out such that say 10 people would be in each boat (since 50/10 = 5).
So in short, the result of p/12 is rounded up to the nearest whole number.

Michael has 567 pennies, Jorge has 464 pennies, and Jamie has 661 pennies. If the pennies are shared equally by the 3 boys and 33 of their classmates, how much money will each classmate receive? ( please show me the steps)
Answer:
Everybody, including the three boys, will get 47 pennies.
Step-by-step explanation:
First, you add the number of pennies each of the boys has, 567+464+661 = 1,692. Then you take the 1,692 and divide it by 36 to get 47. You divide by 36 because the pennies are getting shared by the 3 boys and 33 classmates, which comes out to be 36 classmates in total.
A man invested $10,500 for 7 years at 5 ½ % per annum simple interest.
(A) Determine the simple interest payed
(B) Calculate the amount of money he collected after the period of 7 years
Money invested by a man = $10,500
No.of years for which he invested his money = 7
Rate of interest = 5.5%
We know that :
[tex] \tt \: Simple \: interest = \frac{Principal × Rate × Time}{100} [/tex]
Principal = 10500
Rate = 5.5%
Time = 7 years
Simple interest the man payed :
[tex] = \tt\frac{10500 \times 55 \times 7}{10 \times 100} [/tex]
[tex] = \tt \frac{4042500}{1000} [/tex]
[tex] \color{plum}=\tt 4042.50[/tex]
Therefore, the simple interest payed by the man = $4042.50
Solution (B) :Money invested by the man (principal) = $10,500
The simple interest he payed = $4042.50
We know that :
[tex]\tt \: amount = principal + interest[/tex]
The amount the man collected after a period of 7 years :
[tex] = \tt10500 + 4042.50[/tex]
[tex] =\tt 14520.50[/tex]
Thus, amount = $14520.50
Therefore the amount he collected after a period of 7 years = $14520.50

Steve has 1 1/2 cups of flour. One of his recipes requires 1/8 cup of flour. What is the maximum number of times (batches) Steve can complete the recipe?
Answer:
12 batches
Step-by-step explanation:
Total cups of flour = 1 1/2
Flour used per batch = 1/8 cups
What is the maximum number of times (batches) Steve can complete the recipe?
Maximum batches Steve can make = Total cups of flour / Flour used per batch
= 1 1/2 ÷ 1/8
= 3/2 ÷ 1/8
= 3/2 × 8/1
= (3*8) / (2*1)
= 24 / 2
= 12 batches
Maximum batches Steve can make = 12 batches

help me plz plz plz geometry
Answer:
64
Step-by-step explanation:
Answer:
x = 8°, y = 28°
Angles are 64° and 116°
Step-by-step explanation:
Parallelogram
Opposite angles of a parallelogram are congruent, that is, they have the same measure, thus:
4y = y + 87
8x = 7x + 8
These are two separate equations that can be solved independently.
Subtracting y to the first equation:
3y = 87
Dividing by 3:
y = 87/3 = 29
y = 29°
Subtracting 7x to the second equation:
x = 8°
The internal angles of the parallelogram are:
8x = 64°
4y = 116°
The question doesn't have any specific requirements, so I solved the variables and calculated the angles.
3x+2y=5
What is the y and x intercept and can i get a step by step explanation
Answer:
the slope is -3/2, and the y-intercept is 5/2.
Step-by-step explanation:
3x + 2y = 5
putting it into a y = mx+b form,
2y = -3x + 5
y = -3/2x + 5/2
the slope is -3/2, and the y-intercept is 5/2.
Answer:
y-intercept= 2.5
x- intercept= 1.666666666..... or 5/3
Step-by-step explanation:
1. Move variable to other side.
3x+2y= 5
-3x -3x
2y= -3x+5
2. Divide each side by 2.
-3/ 2 = -1.5
5/2 = 2.5
y= 1.5x+2.5
y= mx+b
b= y-intercept
b=2.5
3. Replace y with 0 to solve for x intercept.
3x+ 2 x 0 = 5
3x= 5
5/3 = x

Why is 4 +(-3) equal to 1
Answer:
bc u really subtracting three
Step-by-step explanation:
several ways to explain this, but the simplest way to show this is using a number line.
See attached for number line.
If we start at zero and add 4 (i.e the blue line) we will get a value of 4.0
subsequently, if we subtract 3 from this (green line), we will end up at 1.
