Question is below PLEASE HURRY I'M DESPERATE
Answer:
a) 15.5 cm
b) 37.2 cm
Step-by-step explanation:
For part a you would write 4(x+1) because perimeter is adding the sides and all sides of a square are equal. then you would set that equal to 66 and get 4(x+1)=66 and then distribute the 4 and get 4x+4=66 and then subtract the 4 from 66 and get 4x=62. Then you divide 62 by 4 and get 15.5.
For part b you do essentially the same thing but set it equal to 152.8 and get 4(x+1)=152.8 and then distribute the 4 to get 4x+4=152.8 then subtract the 4 and get 148.8 and then divide that by 4 and get 37.2.
Answer:
Step-by-step explanation:
a) Length = (x +1) cm
Perimeter of square = 66 cm
4 * length = 66
4* (x +1) = 66
Divide both sides by 4
[tex]\frac{4*(x +1)}{4}=\frac{66}{4}[/tex]
x + 1 = 16.5
Subtract 1 from both sides,
x = 16.5 -1
x = 15.5 cm
b) Length = (x +1) cm
Perimeter of square = 152.8 cm
4 * length = 152.8
4* (x +1) = 152.8
Divide both sides by 4
[tex]\frac{4*(x +1)}{4}=\frac{152.8}{4}[/tex]
x + 1 = 38.2
Subtract 1 from both sides,
x = 38.2 -1
x = 37.2 cm

f(19)=5(19+4)-6
*Add 19 + 4 because it is in ()* f(19)=5(23)-6
*Multiply because it is the first in the order of operations* f(19)=115-6
*Now just subtract* f(19)= 109
Vanessa and zack are playing a game where a player with the lower score wins at the end of the game Vanessa has a score of -3 5/8 and zack has a score of -3 2/3 which statement explains who won
Complete question :
Vanessa and Zack are playing a game where the player with the lower score wins. At the end of the game, Vanessa has a score of -3 5/8 and Zack has a score of -3 2/3. Which statement explains who won?
Vanessa won. If you compare the decimal equivalents of their scores, -3.625 < -3.666.
Vanessa won. If you compare the decimal equivalents of their scores, -3.666 < -3.625.
Zack won. If you compare the decimal equivalents of their scores, -3.625 < -3.666.
Zack won. If you compare the decimal equivalents of their scores, -3.666 < -3.625
Answer: Zack won. If you compare the decimal equivalents of their scores, -3.666 < -3.625
Step-by-step explanation:
Given that :
Player with the lowest score wins ;
Vanessa's score = - 3 5/8
Zack's score = - 3 2/3
Converting to decimal:
Vanessa :
-3 5/8 = - 29 /8 = - 3.625
Zack:
-3 2/3 = - 11/3 = - 3.666
Comparing the scores :
From the negaryce side of a number line :
-3.666 comes before - 3.625, hence, - 3.666 is lower or lesser than - 3.625
-3.666 < - 3.625, hence Zack won
Answer:
D. Comparing the decimal equivalents of their scores shows that Zack won because -3.6 (line over 6) if less than -3.625.

4x + 3y = 26 3x - 2y=11
Answer:
x = 5
Step-by-step explanation:
2 (4x + 3y = 26)
3 (3x - 2y = 11)
8x + 6y = 52
9x - 6y = 33 [the 6y and -6y cancel out]
17x = 85 [divide both sides by 17 to find x]
x = 5
Step-by-step explanation:
Hey, there!!
Given,
4x + 3y = 26........(i)
3x -2y = 11............(ii)
Multiplying equation (i) by 2 and equation (ii) by 3 we get,
8x - 6y = 52
9x + 6y = 33
17x = 85 { cancelling 6y and -6y}.
[tex]x = \frac{85}{17} [/tex]
Therefore, x= 5.
Now, putting the value of x is equation (i)
4x + 3y = 26
4×5 + 3y = 26
20 + 3y = 26
3y = 26 -20
[tex]y = \frac{6}{3} [/tex]
Therefore, y = 2.

Answer:
x = 95
Step-by-step explanation:
The sum of the angles of a quadrilateral is 360
x +115+46+ 104 = 360
Combine like terms
x+265=360
Subtract 265 from each side
x +265-265 = 360-265
x = 95

What is the greatest common factor of 18 and 35
The greatest common factor of 18 and 35 is 1.
What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
The greatest common factor of 18 and 35.
Now,
See all the factors of 18.
= 1, 2, 3, 6, 9, and 18.
See all the factors of 35.

The greatest common factor is 1.
Thus,
The greatest common factor of 18 and 35 is 1.

Effects of Shifting, Adding and Removing Data
Pamela works at the zoo. She was looking at some data showing the weight of their 4 giraffes. The mean of weight of the giraffes was 1,800 pounds and the median weight was 2,000 pounds. Then gets a baby giraffe that weighs 500 pounds. How would the addition of the baby giraffe affect the mean and median?
Chose one:
• Both the mean and median increased.
• Both the mean and median decreased.
• The mean increased, but the median decreased.
• The median increased, but the mean decreased.
Answer: Both the mean and median decreased.
Step-by-step explanation:
The addition of the 500 lb baby elephant will have a huge impact on the mean, since you'll be finding the average (adding all numbers then dividing). So the only logical answer would be the chosen. The median will most likely either decrease or stay the same, but since staying the same isn't an option for the median, it's most likely going to be decrease.

What is 10a - 5b if a = 25 and b = 3
Answer:
[tex]\boxed{235}[/tex]
Step-by-step explanation:
Hey there!
Well given that,
a = 25
b = 3
10(25) - 5(3)
250 - 15
= 235
Hope this helps :)
Hi there! Hopefully this helps!
-------------------------------------------------------------------------------------------------------
Answer: 235.~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~First we need to substitute the value of the variable into the expression:
10a - 5b = 10(25) - 5(3).
Now we Multiply 10 and 25 to get 250.
250 − 5 × 3 = 235
Multiply 5 and 3 to get 15.
250 − 15 = 235
Subtract 15 from 250 to get, you guessed it, 235!what are scaled copies? and how to use them?
Answer:
A scale copy of a figure is a figure that is geometrically similar to the original figure. This means that the scale copy and the original figure have the same shape but possibly different sizes. First you have to look at one of the sides of the scaled copy. If they are divisible by the numbers in the original shape, then try and see if the others sides of the scaled copy are scaled by the same factor. If they are, then they are a scaled copy.

If a dog moves 3 meters due East and then 4 meters due North, what will be the dispalcement of the dog?
Answer:
The displacement of the dog which is the shortest distance between the two points is 5 meters 53.13° North of East
Step-by-step explanation:
The given parameters are;
The dog's displacement due East = 3 meters
The dog's displacement due North = 4 meters
The displacement, D motion of the dog can be written in vector form as follows;
D = 3i + 4j
The magnitude of the displacement is given as follows;
[tex]\left | D\right | = \sqrt{(3 \ meters)^2 + (4 \ meters)^2} = \sqrt{25 \ meters^2} =5 \ meters[/tex]
The displacement is the shortest distance between two points
The direction is given tan⁻¹(4/3) = 53.13° North of East
The displacement of the dog which is the shortest distance between the two points = 5 meters 53.13° North of East.

The ideal gas equation says that the product of the pressure, P, and the volume of a gas, V, is equal to the number of miles of the gas,n, times the gas constant, R, times the temperature of gas,T.
PV=nRT
which of the following equations is equivalent to the ideal gas equation?
Algebra 1
Answer:
T=PV/nR
Step-by-step explanation:
Use the division property of equality to solve the ideal gas equation for T. Divide both sides of the equation by nR, then simplify.
PV=nPT
PV/RT=nRT/nR
PV/nR=T
Therefore, the equation below is equivalent to the ideal gas equation.
T= PV/nR
