Answer:
The ratios of the lengths of the corresponding sides of the two pentagons is 3:1
The ratios of the perimeters of the two pentagons is 3:1
Step-by-step explanation:
Let the first pentagon be X and the second pentagon be Y.
Ratio of area of the two pentagons is [tex]\frac{A1}{A2} = \frac{9}{1}[/tex]
Ratio of sides of the pentagon is equal to
[tex]\frac{S1}{S2} = \sqrt{\frac{A1}{A2} }\\=\sqrt{\frac{9}{1} } \\=\frac{3}{1}[/tex]
Ratio of perimeters is equal to ration of sides
Hence,
[tex]\frac{P1}{P2} = \frac{3}{1}[/tex]

Answer:
the right answer is:
(A) [tex]2+\frac{1}{2}a[/tex]Step-by-step explanation:
You take the equations that the exercise give you:
x + y = 4x - y = aNow you clear the "y" variable in any equation you want, in this case, I'm gonna use the second equation:
x - y = a-y = a - x3. y = x - a
And now, you'll replace this third equation in the equation you didn't take (the first in this case).
x + y = 4x + (x - a) = 4x + x - a = 4Add the x variables:
2x - a = 42x = 4 + ax = (4 + a) / 2That's the answer of the exercise, but you can represent this in this form:
x = (4 + a) / 2 ↔ [tex]x = \frac{4}{2} + \frac{1}{2} a[/tex]x = (4 + a) / 2 ↔ [tex]x = 2+ \frac{1}{2} a[/tex]By this reason, the right answer is [tex]x = 2+ \frac{1}{2} a[/tex].
To prepare for a bake-off, Rebecca used 0.83 kilogram of flour each day for 3 weeks. How many grams did Rebecca use in those 3 weeks?
Answer:
17,430g
Step-by-step explanation:
convert kilogram to gram
1kg = 100g
0.83 x 1000 = 830g
there are 7 days in a week
7 x 3 = 21 days
total grams used in 3 weeks = 21 x 830 = 17,430g
factorise fully the following
3 x + 6
Answer:
[tex]3x + 6 = 0 \\ 3x = 0 - 6 \\ 3x = - 6 \\ x = \frac{ - 6}{3} \\ x = - 2[/tex]

Flip a fair coin 5 times. Let random variable X = "number of heads."What is P(X = 1)?
Answer:
The probability is 1/32
Step-by-step explanation:
What the question asks here is that in a throw of a coin 5 times, what is the probability that we have the head being revealed once in the 5 throws
for a fair coin, we can only get a head or a tail
So the probability of getting a head equals that of getting a tail
Since total probability is 1; then the probability of each will be 1/2
So, we can now have the probability as follows;
1 head (1/2) and 4 tails (1/2 * 1/2 * 1/2 * 1/2)
1/2 * 1/2 * 1/2 * 1/2 * 1/2 = (1/2)^5 = 1/32

Nick is stuck at the top of a Ferris wheel. His mother is standing 38 feet from the base of the wheel watching him. If the angle of elevation from nick's mom to nick is 73, how far off the ground is nick?
Answer:
124.3 ft
Step-by-step explanation:
We solve the above question using the Trigonometric function of Tangent
= tan θ = Opposite/Adjacent
θ = Angle of Elevation = 73°
Adjacent = 38 ft
Opposite = x
Hence
tan 73° = x/38 ft
Cross Multiply
x = tan 73° × 38 ft
x = 124.2923995 ft
Approximately = 124.3 ft
Therefore, Nick is 124.3 ft from the ground.

Answer:
77 represents the starting temperature; the temperature after 2 minutes will be 177 degrees
Step-by-step explanation:
77 in Brooklyn's equation represent the oven's temperature after o minutes.
What is slope intercept form of line?The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
Given,
Brooklyn wants to predict the final temperature after 2 minutes.
the equation y = 77 + 50x,
y represents the final temperature in degrees Fahrenheit
We need to find what the number 77 represents in the equation.
77 represents the initial temperature of the oven.
50x represents the change in the temperature of the oven.
Hence, 77 in Brooklyn's equation represent the oven's temperature after o minutes.

Statements are (underlined) and reasons are (bolded).
It is given that (<W) and (<Y) are both right angles, therefore, they must be congruent since they have the same angle measures.
<W = <Y definition of right angles
Moreover, it is given that (VX) and (ZX) are congruent.
VX = ZX given
Finally, it is given that (x) is the midpoint of (WY). Therefore, (WX) is congruent to (XY), and therefore, they are congruent.
WX = XY definition of midpoint
Thus, triangle (YWX) is congruent to (ZYX) by the following rule, side-angle-side, also known as (SAS).
YWX = ZYX SAS
When two sides and an angle are congruent between two or more triangles, then those triangles must be congruent.

Solve the equation sin^2x= 3 cos^2x.
The value of x that satisfies the equation if x lies in the second quadrant is what degrees?
The value of x that satisfies the equation if x lies in the third quadrant is what degrees?
Step-by-step explanation:
sin^2(x)= 3 cos^2(x)
Subtract sin^2(x) on both sides
0=3cos^2(x)-sin^2(x)
By Pythagorean Identity sin^2(x)+cos^2(x)=1, we can replace cos^2(x) with 1-sin^2(x)
0=3(1-sin^2(x))-sin^2(x)
Distribute
0=3-3sin^2(x)-sin^2(x)
Combine like terms
0=3-4sin^2(x)
Add 4sin^2(x) on both sides
4sin^2(x)=3
Divide both sides by 4
sin^2(x)=3/4
Take the square root of both sides
sin(x)=+ or - sqrt(3/4)
sin(x)=+ or - sqrt(3)/sqrt(4)
sin(x)=+ or - sqrt(3)/2

3 daily attendance at the water park: 346, 250, 433, 369, 422,298
Find the median, Q1, Q3,and IQR
Answer:
Median --> 357.5
Q1 --> 298
Q3 --> 422
IQR > 124
Step-by-step explanation:
3 daily attendance at the water park: 346, 250, 433, 369, 422,298
Find the median, Q1, Q3,and IQR
Step 1
We rearrange the given data set
250, 298, 346, 369, 422, 433
a) The Median
The formula to find the Median
= 1/2( n + 1)th term
Where n = Number of terms = 6
Median = 1/2(6 + 1)th
= 1/2(7)th term
= 3.5th term
The 3.5th term = The number between the 3rd and 4th term
3rd term = 346
4th term = 369
Hence,Median = 346 + 369/2
= 357.5
2) Q1 = First Quartile
= 1/4(n + 1)the
= 1/4( n + 1)th term
Where n = Number of terms = 6
Median = 1/4(6 + 1)th
= 1/4(7)th term
= 1.75th term
The 1.75th term = 2nd term
= 298
Q1 = 298
3) 3/4( n + 1)th term
Where n = Number of terms = 6
Median = 3/4(6 + 1)th
= 3/4(7)th term = 21/4th term
= 5.25th term
The 5.25th term = 6th term
Q3 = 422
4) Interquartile Range = Q3 - Q1
= 422 - 398
= 124

The amount of money, A, accrued at the end of n years when a certain amount, P, is invested at a compound annual rate, r, is given by A= P(1+r) If a person invests $310 in an account that pays 8% interest compounded annually, find the balance after 5 years.
Answer:
A = $455.49
Step-by-step explanation:
A= P(1+r) ^t
P = $310
R = 8% or 0.08
T = 5
Put variables in the above equations
A = 310 (1+0.08)^5
A= 310(1.08) ^ 5
A = $455.49

For what values of x is the trinomial 2x2−x+55 equal to the square of binomial x+5?
The value of x for which the trinomial 2x^2−x+55 equal to the square of binomial x+5 is 5 and 6
Given the equation 2x^2−x+55, if the expression is equal to the square of binomial x + 5, then;
2x^2−x+55 = (x+5)^2
2x^2−x+55 = x^2 + 10x + 25
Collect the like terms;
2x^2-x^2-x-10x+55-25 = 0
x^2 - 11x + 30 = 0
Factorize the result
x^2 - 6x - 5x + 30 =0
x(x-6)-5(x-6) = 0
x-5 = 0 and x - 6 = 0
x = 5 and 6
Hence the value of x for which the trinomial 2x^2−x+55 equal to the square of binomial x+5 is 5 and 6
