Ibrahim has 33 more stickers than Rosie
EquationAn equation is an expression used to show the relationship between two or more variable and numbers.
Given the ratio:
Rosie: Matilda: Ibrahim = 4 : 7 : 15
Let x represent the total number of stickers
Ibrahim = (15/26)x
Matilda = (7/26)x
Given:
(15/26)x = (7/26)x + 24
x = 78
Ibrahim = (15/26)*84 = 45
Rosie = (4/26)*84 = 12
Ibrahim has 33 (45 - 12) more stickers than Rosie

Convert to a mixed number in simplest form 2/15 + 14/15 =
[tex][Hello,BrainlyUser][/tex]
Answer:
[tex]1\frac{1}{15}[/tex]
Step-by-step explanation:
To Convert to a mixed number..
First, Let's add both fraction.
[tex]\frac{2}{15} + \frac{14}{15}[/tex]
The two fractions have like denominators so you can add the numerators.
[tex]\frac{2+14}{15}=\frac{16}{15}[/tex]
The fraction
[tex]\frac{16}{15}[/tex]
is the same as
[tex]16[/tex] ÷ [tex]15[/tex]
Convert to a mixed number using
long division for 16 ÷ 15 = 1R1, so
[tex]\frac{16}{15}=1\frac{1}{15}[/tex]
Therefore,
[tex]\frac{2}{15}+\frac{14}{15}=1\frac{1}{15}[/tex]
Hence, your answer is 1 1/15

Answer:
C = (12, 13)
Step-by-step explanation:
The centre of the rectangle is O.
Find the difference between the x and y-values of O and A:
[tex]O_x-A_x=\dfrac{21}{2}-9=\dfrac32[/tex]
[tex]O_y-A_y=\dfrac{19}{2}-6=\dfrac72[/tex]
Now add those difference to the coordinates of O to find C:
x value of C = [tex]O_x+\dfrac32=\dfrac{21}{2}+\dfrac32=\dfrac{24}{2}=12[/tex]
y value of C = [tex]O_y+\dfrac72=\dfrac{19}{2}+\dfrac72=\dfrac{26}{2}=13[/tex]
Therefore, the coordinates of C = (12, 13)
Answer:
Step-by-step explanation:
In rectangle the diagonals bisect each other. So,O is the midpoint of AC
[tex]Midpoint = \left(\dfrac{x_{1}+x_{2}}{2},\dfrac{y_{1}+y_{2}}{2} \right)\\\\\\x_{1}=9 \ and \ y_{1}=6\\\\\left(\dfrac{9+x_{2}}{2},\dfrac{6+y_{2}}{2} \right) = \left (\dfrac{21}{2},\dfrac{19}{2} \right)[/tex]
Compare the x- coordinates and y- coordinates
[tex]\dfrac{9+x_{2}}{2}=\dfrac{21}{2} \ ; \ \dfrac{6+y_{2}}{2}=\dfrac{19}{2}\\\\\\9+x_{2}=\dfrac{21}{2}*2 \ ; \ 6 +y_{2}=\dfrac{19}{2}*2[/tex]
9 + x₂ = 21 ; 6 +y₂ = 19
x₂ = 21 -9 ; y₂ = 19 - 6
x₂ = 12 ; y₂ = 13

You roll a 6-sided die and toss a coin.
What is the probability of rolling a
number greater than 2 and then
getting tails?
Answer:
Answer: 1/3
Step-by-step explanation:
The probability of getting tails when tossing a coin is 1/2
The probability of rolling a number greater than 2 is 4 (3 4 5 6)
So 4/6 or 2/3 of the time is the probability of throwing the die and getting a number greater than 2.
The combined probability of getting both is 1/2 * 2/3 = 2/6 or 1/3
Solve the system of linear equations using substitution. Use pencil and paper. Which expression would be easier to substitute into the other equation, in order to solve this problem? Explain your reasoning.
x = 2y - 5
x + 2y = 4
Answer:
substitute for x(x, y) = (-1/2, 9/4)Step-by-step explanation:
When solving a system of equations using substitution, you look for an equation that makes it simple to write an expression for one of the variables in terms of the other(s). Here, the first equation already gives you an expression for x, so it is easiest to substitute for x in the second equation:
(2y -5) +2y = 4 . . . . . . (2y-5) substituted for x
4y = 9 . . . . . . . . . . add 5 and simplify
y = 9/4 . . . . . . . . divide by 4
x = 2(9/4) -5 = 9/2 -10/2 = -1/2
The solution is (x, y) = (-1/2, 9/4).

At a theme park, the waiting time for the roller coaster is usually 3 times as long as the waiting time for the bumper cars. The park's website says that visitors who go on both rides should expect to wait a total of 30 min. What is the usual waiting time for the bumper cars? Show your work.
Using a system of equations, it is found that the usual waiting time for the bumper cars is of 7.5 min.
What is a system of equations?A system of equations is when two or more variables are related, and equations are built to find the values of each variable.
In this problem, the variables are:
Variable x: Waiting time for roller coaster.Variable y: Waiting time for bumper cars.The waiting time for the roller coaster is usually 3 times as long as the waiting time for the bumper cars, hence:
x = 3y
The park's website says that visitors who go on both rides should expect to wait a total of 30 min, hence:
x + y = 30
Since x = 3y:
3y + y = 30
4y = 30
y = 30/4
y = 7.5.
The usual waiting time for the bumper cars is of 7.5 min.

The transportation department has to put a railing along the outer curve of this road. The road is 20 feet wide. What is the length of the outer curve to the nearest foot? Use the value = 3. 14. A. 68 feet B. 74 feet C. 86 feet D. 92 feet E. 102 feet.
Answer:
A. 68 feet ( the length of the outer curve to the nearest foot
Option C is correct, the the length of the outer curve to the nearest foot is 86 feet.
The formula for length of arc to find the length of the outer curve.
Thus; Arc Length = radius ×angle
We are given;
Radius = 70 ft
Angle = 70° = 70 × π/180 radians
Thus;
Arc length = 70 × (70 × π/180)
Arc length = 86 ft
Therefore, the outer curve is 86 feet long. Option C is correct.

Selena was finding the area of a circle with the radius of 7 units. Her work is shown below:
A = πr^2
= 3.14 * 7^2
= 3.14 * 14
= 43.96 units^2
What should Selena do to correct the error that she made?
F. Use 14 for the value of r .
G. Use 3.5 for the value of r .
H. Use 49 instead of 14 for 7^2
I. Use the formula 2πr
(Please show your work if possible!)
