Answer:
Yes
Step-by-step explanation:
Yes ,a rational number is a number that can be expressed as a fraction. Repeating and terminating decimal are rational number so
5/6 is right since it is a fraction
6.565646 is right since it is a repeating decimal
0.23 is right since it is a terminating decimal
-5 3/8 is right since it is a mixed number
Sqr root of 11 and 0.32416.... is wrong since it creates multiple random unknown digits

Step-by-step explanation:
The triangle provided is an equilateral one, which means that the length of all sides is equal.
Let's start by taking two and finding x.
8x+1 = 3x+6 (Subtract 3x from both sides)
5x+1 = 6 (Subtract 1 from both sides)
5x = 5 (Divide 5 from both sides)
x = 1
Now we substitute x in all the equations to find the length.
8(1) + 1 = 9
3(1) + 6 = 9
4(1) + 5 = 9
Length = 9
Write a system of equations. Reserved seat tickets for the football game cost $4.00 each and general admission tickets cost $3.00 each. After the game is over, the turnstile count shows 1787 people attended the game. The total receipts were $5792. WRITE BOTH EQUATIONS FOR THIS SYSTEM.
Answers
Answer:
Step-by-step explanation:
If you are looking for an equation then it is:
4x + 3y = 1787 (Where x is the reserved seat tickets and y is general admission)
and $4x + $3y = $5792

t=bd+M solving M what's the answer
Answers
Answer:
m=−bd+t
Step-by-step explanation:
t=bd+m
flip equation
bd+m=t
Step 2: Add -bd to both sides.
bd+m+−bd=t+−bd
m=−bd+t
On solving for M, we get -
M = t - bd
We have the following expression -
t = bd + M.
We have to solve for ' M '.
Solve for x : nx + a = [tex]$\pi[/tex].On solving, we get -
nx + a = [tex]$\pi[/tex]
x = [tex]$\frac{\pi -a}{n}[/tex]
According to the question, we have -
t = bd + M
t - bd = M
M = t - bd
Hence, on solving for M, we get -
M = t - bd

Step 2: 12x – 12x – 15 = 7x + 20
Step 3: -15 = 7x + 20
Step 4: -35 = 7x
Step 5: -5 = 3
Drag and drop the correct justification for each step.
Answers
Step-by-step explanation:
step 1. 12x - 15 - 12x = 7x + 20
step 2. 12x - 12x - 15 = 7x + 20 (grouping of terms)
step 3. -15 = 7x + 20 (adding like terms)
step 4. -35 = 7x (subtract 20 from both sides)
step 5. this step is incorrect.
step 6. -5 = x ( divide both sides by 7)
step 7. x = -5 (put the variable first).

Answers
Answer:
1,2 = 1,negative2
3,6 = 3,negative 6
-1,2 = negative 1, negative 2
-2,-2 = negative2, 2
Step-by-step explanation:
Sorry all i could do was reflect the coordinates across the x-axis.
The figure reflected along x-axis will have vertices A(1, -2), B (3, -6), C(-1, -2), and D(-2, 2).
What is reflection along the x-axis?When we reflect a figure along the x-axis the coordinate point of y changes its sign, (x, y) becomes (x, - y).
Think of holding the x-axis with two fingers and rotating it.
Given, we reflect a figure with vertices A(1,2) B (3,6), C(-1,2), and D(-2,-2)
across the x-axis.
∴ The rotated coordinate will be A(1, -2), B (3, -6), C(-1, -2), and D(-2, 2).

Answer:
Angle B and Angle D are both 101 degrees
Step-by-step explanation:
Consecutive Angles in a parallelogram are supplementary (add up to 180 degrees).
Given that fact, we can deduce the measure of angle B.
180-79=101.
Angle D has the same setup since Angle D and C are consecutive along with Angle C and B.
180-79=101.
Therefore, both Angle B and D are 101 degrees.

How much net work is required to accelerate a 1000 kg from 20 m/s to 30
m/s?
Answers
Answer:
Work= force(F) * distance (s)
weight is a force and so
F=weight=mass *acceleration due to gravity
=1000*10=10000N
S=?
To find s,
F= ma
a=F/m=10000/10
a=10m/s²
Using Newton's third equation of motion
v²= u²+2as
30²= 20²+2*10*s
900–400=20s
500=20s
s=500/20= 25m
Work =F*s
Work=10000*25
Work= 250000J or 250KJ

A Cepheid variable star is a star whose brightness alternately increases and decreases. Suppose that Cephei Joe is a star for which the interval between times of maximum brightness is 6 days. Its average brightness is 3.5 and the brightness changes by /-0.25. Using this data, we can construct a mathematical model for the brightness of Cephei Joe at time t, where t is measured in days: B(t)=4.2 +0.45sin(2pit/4.4)
A) Find the rate of change of the brightness after t days.
B) Find the rate of increase after one day.
Answers
Answer:
a) The rate of change of the brightness after t days is [tex]B^{\prime}(t) = 0.204525\pi\cos{(0.4545\pi t)}[/tex]
b) The rate of increase after one day is of 0.0915.
Step-by-step explanation:
The brightness after t days is given by:
[tex]B(t) = 4.2 + 0.45\sin{(\frac{2\pi t}{4.4})} = 4.2 + 0.45\sin{(0.4545\pi t)}[/tex]
A) Find the rate of change of the brightness after t days.
This is [tex]B^{\prime}(t)[/tex]
The derivative of a constant is 0, the derivative of [tex]\sin{at}[/tex] is [tex]a\cos{at}[/tex]
So, in this case, we have that:
[tex]B^{\prime}(t) = 0.45*0.4545\pi\cos{(0.4545\pi t)} = 0.204525\pi\cos{(0.4545\pi t)}[/tex]
The rate of change of the brightness after t days is [tex]B^{\prime}(t) = 0.204525\pi\cos{(0.4545\pi t)}[/tex]
B) Find the rate of increase after one day.
This is [tex]B^{\prime}(1)[/tex]. So
[tex]B^{\prime}(1) = 0.204525\pi\cos{(0.4545\pi)} = 0.0915[/tex]
The rate of increase after one day is of 0.0915.

1) : 2x + 5y = 12 a. (1,?) b. (?, 1) C. (0,?) d. (?, 0)
Answers
Answer:
A. y = 2
B. x = 7/2
C. y = 12/5
D. x = 6
Step-by-step explanation:
A. Determination of y .
2x + 5y = 12
x = 1
2(1) + 5y = 12
2 + 5y = 12
Collect like terms
5y = 12 – 2
5y = 10
Divide both side by 5
y = 10 / 5
y = 2
B. Determination of x
2x + 5y = 12
y = 1
2x + 5(1) = 12
2x + 5 = 12
Collect like terms
2x = 12 – 5
2x = 7
Divide both side by 2
x = 7/2
C. Determination of y
2x + 5y = 12
x = 0
2(0) + 5y = 12
0 + 5y = 12
5y = 12
Divide both side by 5
y = 12/5
D. Determination of x
2x + 5y = 12
y = 0
2x + 5(0) = 12
2x + 0 = 12
2x = 12
Divide both side by 2
x = 12/2
x = 6
