A rectangle has side lengths of 2 units and 4 units. Can you form a different quadrilateral using the same four side lengths? Explain why or why not Support your explanation with drawings. please explain this for me. im so lost
Answer:
a kite
Step-by-step explanation:
Yes, you can form a kite. The top two would be 2 units, and the bottom two would be 4 units. It would still have two of each, just like the rectangle, but would be a different quadrilateral.
Alternately, you could turn the rectangle into a parallelogram by leaning it. Rectangles have 90 degree angles, so it wouldn't be a rectangle anymore.

What is the mass of the Apple juice with a volume of 200.0 mL? The density of apple juice is 0.789 g/mL.
Answer:
mass = 157.8 gStep-by-step explanation:
The mass of a substance when given the density and volume can be found by using the formula
mass = Density × volumeFrom the question
Density = 0.789 g/mL
volume = 200 mL
Substitute the values into the above formula and solve for the mass
That's
mass = 0.789 × 200
We have the final answer as
mass = 157.8 gHope this helps you
4(-x+4)=12 multi step equation
Answer:

Step-by-step explanation:
4(-x+4)=12
first is to open the bracket giving u
-4x+16=12
since 16 is adding where it is when takrn to the other side it will be subtracting giving u
-4x=12-16
-4x=-4
x= -4/-4
x=1
Sally shot her bow and arrow straight up into the air and she found the maximum height that her arrow reached was 30ft , but she wants to know how long it took to get there , what does she need to find ?
Answer:
Sally would need two kinematic equations and know the values of gravitational acceleration to obtained the time taken by the arrow to reach maximum height.
Step-by-step explanation:
Sally shot her bow and gravity influences entirely on the motion of the bow, since distances are to small with respect to the radius of the Earth, gravitational acceleration can be considered constant. When arrow reaches maximum arrow, final velocity is zero. In consequence, the position of the arrow can be expressed in terms of the following kinematic equations:
[tex]y - y_{o} = v_{o}\cdot t +\frac{1}{2} \cdot g\cdot t^{2}[/tex]
[tex]0 = v_{o}+g\cdot t[/tex]
Where:
[tex]y_{o}[/tex], [tex]y[/tex] - Initial and final height of the arrow, measured in feet.
[tex]v_{o}[/tex] - Initial velocity, measured in feet per second.
[tex]g[/tex] - Gravitational acceleration, measured in feet per square second.
[tex]t[/tex] - Time, measured in seconds.
In consequence, Sally would need two kinematic equations and know the values of gravitational acceleration to obtained the time taken by the arrow to reach maximum height.

What does "when x is an integer" mean?
Answer:
x = whole-valued numbers without fractions or decimal.
Step-by-step explanation:
An integer in mathematics refers to a whole number that can either be a positive or negative number but without any fractional part. Integers are numbers such as -5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5 etc.
Hence, when we say "x" is an integer, it simply means that the value of x should be a whole number that can either be a positive or negative number but without any fractional or decimal value or part.
In Mathematics, when solving for an unspecified or unknown integer we can use a lowercase alphabet "x" to denote the integer.
For instance;
2x + 5 = 11
2x = 11 - 5
2x = 6
Dividing both sides by 2, we have;
x = 3.

Someone please help me! I only have one attempt left.
Answer:
x=18
Step-by-step explanation:
10x-4+x-14=180
11x-18=180
11x=180+18
11x=198
x=[tex]\frac{198}{11}[/tex]
x=18
Answer:
x = 18
Step-by-step explanation:
(10x -4) + (x-14) = 180 (for linear pair)
<=> 10x + x - 4 - 14 = 180
<=> 11x - 18 = 180
<=> 11x = 180+18 = 18 . 10 + 18 = 18 . 11
<=> x = 18
The diameter of a circle increased from 25cm to 25.8cm. Find the percentage increase in its circumference.
Answer:
3.1% increase
Step-by-step explanation:
Diameter1=25cm
Radius1=12.5cm
Circumference1=2x22/7x12.5
Diameter2=25.8cm
Radius2=12.9cm
Circumference2=2x22/7x12.9
% increase =Circumference2-Circumference1/Circumference2 x 100%= 2x22/7x12.9-2x22/7x12.5 / 2x22/7x12.9 x100%
12.9-12.5/12.9 x 100%
0.4/12.9 x 100%
4/129 x 100%
3.1%

This inequality consists of 3 parts.
To solve this inequality, you will have to add -3 in each part of the inequality.
[tex]1+-3<x+3+-3<5+-3[/tex]
The answer to this is:

Jan noticed that she has four times as many dimes as quarters. She has one more nickel than dimes. The
coins totaled $6.00. How many dimes does Jan have?
Answer:
Jan has 28 dimes.
Step-by-step explanation:
It would take 24 quarters or 60 dimes or 120 nickels to make $6.
So, I simply divided 24 by 3, which is 8 (but I did 7).
7 quarters is 1.75, and 28 dimes make 2.80, and 29 nickels make 1.45
1.75 + 2.80 + 1.45 = $6

$6.06
Step-by-step explanation:
Edward: 36.00*0.87=31.32
Chad 36.00*0.71=25.25

The endpoints of EF
are E(1,3) and F(-2,8).
Find EF.
Answer:
EF = [tex]\sqrt{34}[/tex] ≈ 5.83
Step-by-step explanation:
Calculate EF using the distance formula
d = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]
with (x₁, y₁ ) = E(1, 3) and (x₂, y₂ ) = F(- 2, 8)
EF = [tex]\sqrt{(-2-1)^2+(8-3)^2}[/tex]
= [tex]\sqrt{(-3)^2+5^2}[/tex]
= [tex]\sqrt{9+25}[/tex]
= [tex]\sqrt{34}[/tex] ≈ 5.83 ( to 2 dec. places )

A stocks value decreased by 7 points each day for 2 weeks. Which numeric expression can be used to find out what the stock value was after the 2 weeks?
Answer:
x - 98
Step-by-step explanation:
Given the question :
A stocks value decreased by 7 points each day for 2 weeks. Which numeric expression can be used to find out what the stock value was after the 2 weeks?
Let the initial value of the stock = s
Rate of decrease = 7 points per day
Number of days in a week = 7
Hence, 2 weeks = ( 2 * 7) = 14 days
Total decrease in stock over the 2 weeks period :
(Decrease per day × number of days)
(7 points × 14) = 98 points
Stock value after 2 weeks :
(Initial stock value - decrease in stock over the 2 weeks period)
= x - 98

A 32 ounce soft drink costs $1.83. Approximately what is the price per ounce
Step-by-step explanation:
divide 32 by 1.83 to get the answer
the answer is 17.4863387978
round it off
the final answer should be:
17.5 cents
The price per ounce is approximately 5.72 cents per ounce.
What are the ratio and proportion?The ratio is the division of the two numbers.
For example, a/b, where a will be the numerator and b will be the denominator.
Proportion is the relation of a variable with another. It could be direct or inverse.
Given that,
A 32-ounce soft drink costs $1.83.
So,
32 ounce ⇒ $1.83
Divide by 32 into both sides
1 ounce ⇒ 1.83/32
1 ounce ⇒ $0.0571875 = 5.72 cents.
Hence"The price per ounce is approximately 5.72 cents per ounce".

What is the solution to the proportion? Round the answer to the nearest tenth if necessary. StartFraction 52 over x EndFraction = StartFraction 9.5 over 3.25 EndFraction x = 14.6 x = 17.8 x = 157.8 x = 169.0
Answer: 17.8
Step-by-step explanation:
The solution to the proportion would be x = 17.8 which is the correct option (B).
What is Ratio?A ratio is defined as a relationship between two quantities, it is expressed as one divided by the other
What are Arithmetic operations?Arithmetic operations can also be specified by adding, subtracting, dividing, and multiplying built-in functions. The operator that performs the arithmetic operations is called the arithmetic operator.
/ Division operation: Divides left-hand operand by right-hand operand
For example 4/2 = 2
We have been the given proportion as:
⇒ 52 : x = 9.5 : 3.25
⇒ 52/x = 9.5/3.25
⇒ 52/x = 2.923
Cross multiplication, and we get
⇒ x = 52/2.923
Apply the division operation,
⇒ x = 17.8
Therefore, the solution to the proportion would be x = 17.8.
