Answer:
Dimensions: 11 meters by 27 meters
2. [tex]76=2w+2(2w+5)[/tex]
Step-by-step explanation:
Finding Dimensions:
The perimeter of a rectangle can be written as [tex]2l+2w[/tex] where [tex]l[/tex] is the length and [tex]w[/tex] is the width. It is given that the length is 5 more than twice the length of width and the perimeter of the rectangle is 76 meters.
With this information we can write:
Length = [tex]2w+5[/tex]
[tex]2(2w+5)+2w = 76[/tex] (perimeter of the rectangle)
[tex]4w+10+2w=76[/tex]
[tex]6w=66[/tex]
[tex]w=11[/tex]
Length = [tex]2(11)+5[/tex]
Length = [tex]27[/tex]
∴ The dimensions of the rectangle is 11 meters by 27 meters.
Perimeter
Since the length can be written as [tex]2w+5[/tex], the equation that represents the perimeter of the rectangle is [tex]76=2w+2(2w+5)[/tex]
find 150 of 28 by writing the percent as a decimal
Answer:
28 / 150 = 18.666666666667%
Step-by-step explanation:
28 / 150 = 18.666666666667%
4.45 / 100 = 4.45%
143 / 165 = 86.666666666667%
127,998 / 1,609,008 = 7.955087855374%
Which of the following statements must be true about this diagram? check all that apply.
Answer:
F & B
Step-by-step explanation:
Answer:
C, D, E
Step-by-step explanation:
Remote angles theorem; when one side of a triangle is extended, the angle formed must equal the sum of the two angles in the triangle, that it isn't adjacent to.
C. (m<4) > (m<1), this has to be true because of remote angles theorem.
(m<4) must be greater than (m<1) because it is equal to (m<1) + (m<2)
D. (m<4) > (m<2), apply the same logic here, as was applied to the first problem.
E. (m<1) + (m<2) = (m<4), this is essentially remote angles theorem.

Hello!
[tex]\large\boxed{x^{4}}[/tex]
Recall that:
[tex]\sqrt[z]{x^{y} }[/tex] is equal to [tex]x^{\frac{y}{z} }[/tex]. Therefore:
[tex]\sqrt[3]{x^{2} } = x^{\frac{2}{3} }[/tex]
There is also an exponent of '6' outside. According to exponential properties, when an exponent is within an exponent, you multiply them together. Therefore:
[tex](x^{\frac{2}{3} })^{6} = x^{\frac{2}{3}* 6 } = x^{\frac{12}{3} } = x^{4}[/tex]

is 2(x+3)=5x+6-3x always true or never true?
Answer:
always true
Step-by-step explanation:
Distribute the left side
2(x + 3) = 2x + 6
Simplify the right side
5x + 6 - 3x ← collect like terms
= 2x + 6
Thus
left side = right side , so always true
Equation 2(x + 3) = 5x + 6 - 3x is an identity which is always true.
What is identity?An identity is an equation which is always true, no matter what values are substituted.
Identities can be written with the sign ≡.
Given equation,
2(x + 3) = 5x + 6 - 3x
Simplifying
2x + 6 = 2x + 6
LHS = RHS
Hence, equation 2(x + 3) = 5x + 6 - 3x is always true.

Answer:
c = [tex]\sqrt{90}[/tex]
Step-by-step explanation:
Using Pythagoras' identity in the right triangle.
The square on the hypotenuse c is equal to the sum of the squares on the other 2 sides, that is
c² = 9² + 3² = 81 + 9 = 90 ( take the square root of both sides )
c = [tex]\sqrt{90}[/tex]

(Choice B)
B
[-4,-1][−4,−1]open bracket, minus, 4, comma, minus, 1, close bracket
(Choice C)

(Choice D)
D
[-1,2][−1,2]
Answer:
The option D represents an interval with a positive average rate of change.
Step-by-step explanation:
Let [tex]f(x) = x^{2}+10[/tex], the average rate of change on the interval [tex][a,b][/tex] is represented by the definition of the secant line:
[tex]\bar f = \frac{f(b) -f(a)}{b-a}[/tex] (1)
Where:
[tex]a[/tex], [tex]b[/tex] - Lower and upper bounds, dimensionless.
[tex]f(a)[/tex], [tex]f(b)[/tex] - Function evaluated at lower and upper bounds, dimensionless.
Now we proceed to check each option:
A. [tex]a = -3[/tex], [tex]b = 3[/tex]
[tex]\bar f = \frac{19-19}{3-(-3)}[/tex]
[tex]\bar f = 0[/tex]
B. [tex]a = -4[/tex], [tex]b = -1[/tex]
[tex]\bar f = \frac{11-26}{(-1)-(-4)}[/tex]
[tex]\bar f = -5[/tex]
C. [tex]a = -3[/tex], [tex]b = 1[/tex]
[tex]\bar f = \frac{11-19}{1-(-3)}[/tex]
[tex]\bar f = -2[/tex]
D. [tex]a = -1[/tex]. [tex]b = 2[/tex]
[tex]\bar f = \frac{14-11}{2-(-1)}[/tex]
[tex]\bar f = 1[/tex]
The option D represents an interval with a positive average rate of change.

The bus drives 66 km at an average speed of 24 km/h. How long does the journey take?
Answer:
2.75 hours
Step-by-step explanation:
Speed is 24km per hour ([tex]\frac{24km}{1hour}[/tex]), and the bus covered 66km.
We need to get a value of km with the rate (24/1) and distance (66) given.
We get: [tex]\frac{1hour}{24km} *66km[/tex].
The km cancel out, leaving us with 66/24 hours, or 2.75 hours.

How many solutions can be found for the system of linear equations represented on the graph?
A) no solution
B) one solution
C) two solutions
D) infinitely many solutions
Answer:
D, ininitely many
Step-by-step explanation:
A- incorrect since the lines intersect
B - incorrect since the lines intersect at more than one point
C - incorrect since the lines intersect at more than 2 points
D- correct since the lines intersect at infinitely many points (since they're the same line)
Answer:
D) infinitely many solutions
Step-by-step explanation:
we can see that the graphs shows two lines that are exactly one on top of the other. This means that every point on either line will also coincide with a point on the other line.
Because of this, every point on one line is also a solution on the other line, thus there are infinitely many solutions.

The length of the day in Lagos, Nigeria (in minutes), ttt days since the beginning of the year can be estimated by this formula: \qquad L(t) = 727+22\sin \left(\dfrac{2\pi (t - 80.75)}{365}\right)L(t)=727+22sin( 365 2π(t−80.75) )L, left parenthesis, t, right parenthesis, equals, 727, plus, 22, sine, left parenthesis, start fraction, 2, pi, left parenthesis, t, minus, 80, point, 75, right parenthesis, divided by, 365, end fraction, right parenthesis. When is the longest day of the year? Give an exact answer.
Answer:
The longest day of the year is day 172
Step-by-step explanation:
Since the length of day is L(t)=727+22sin[2π(t−80.75)/365], the maximum length of day is obtained when sin[2π(t−80.75)/365] is at its maximum value which is 1. So. sin[2π(t−80.75)/365] = 1
We now solve this to find the day at which this maximum value occurs.
sin[2π(t−80.75)/365] = 1
[2π(t−80.75)/365] = sin⁻¹(1)
[2π(t−80.75)/365] = π/2
dividing both sides by 2π/365, we have
[2π(t−80.75)/365] ÷ 2π/365 = π/2 ÷ 2π/365
t−80.75 = 365/4
t−80.75 = 91.25
t = 91.25 + 80.75
t = 172
The longest day of the year is day 172
Answer:
172
Step-by-step explanation:
Keep in mind, that when graphed one of the "tallest" points is 172,749. Using this, you'll find that 172 is the tallest

She found that of the 80 people who responded, 0.55 of them preferred FortNite, and 30% of them preferred Among Us. How many more of her friends prefer FortNite than Among Us?
Answer:
20 more of her friends prefer FortNite than Among Us
Step-by-step explanation:
Lynne was wondering which game was more popular so she aksed her friends which they liked to play more, FortNite or Among Us.
She found that of the 80 people who responded:
For fortnite:
0.55 of them preferred FortNite
Hence, = 0.55 × 80 people
= 44 people preferred fortnite
For Among us
30% of them preferred Among Us.
= 30% × 80 people
= 30/100 × 80 people
= 24 people preferred Among us.
How many more of her friends prefer FortNite than Among Us?
This is calculated as:
44 - 24
= 20 more people
Hence, 20 more of her friends prefer FortNite than Among Us
Answer:
20 more of her friends prefer Forte than Among
