The interior angles formed by the sides of a quadrilateral have measures that sum to 360°.
What is the value of x?
Answer:
x = 59
Step-by-step explanation:
combine all four angle measure expressions and set equal to 360°, then solve
x + x + 2x + 3 + 2x + 3 = 360
6x + 6 = 360
6x = 354
x = 59

The height of the red triangle is 1/2 the top or bottom white triangle. That's because the diagonals and the horizontal line all meet in the middle.
The base of the red triangle is equal to 1/2 the length of the base.
Formula
Area red = 1/2 b * h
Solution
b = 1/2
h = 1/2
Area = 1/2 * 1/2 * 1/2
Area = 1/8

Which of the following constants can be added to x^2- 3x to form a perfect square trinomlal?
A. 2 1/4
B. 1 1/2
C. 4 1/2
Answer:
A 21/4
Step-by-step explanation:
When forming a perfect square trinomial you need to "complete the square".
All of the steps to completing the square when solving an equation:
1. The leading coefficient must be 1.
2. Divide b by 2.
3. Square (b/2)
4. Add (b/2)^2 to both sides to keep the polynomial balanced.
5. You can now write the perfect square trinomial and solve.
x^2 - 3x
-3/2
(-3/2)^2 = 9/4 = 2 1/4
Use the following numbers, 4, 30, and 21 to create an equation equal to 1. You may only use each number once. You can use any operation you want to.
Answer:
sqrt(30-21)-sqrt(4)=1
Step-by-step explanation:
I found that sqrt(30-21)-sqrt(4)=1 since sqrt(30-21)=sqrt(9)=3 and sqrt(4)=2 so 3-2=1

During the day, Lola's dog is tied by rope to a tree in the center of her yard. The scale drawing below shows the area that the dog has to run, in inches. If the actual length of the rope is 11 2/3 feet, what is the scale used in the drawing?
Answer:
5 /448
Step-by-step explanation:
Radius in drawing = 1 9/16 in
The actual length of rope = 11 2/3 feets
Converting actual length to inches :
1 feet = 12 inches
11 2/3 feets = (11 2/3) * 12 = 140 inches
To obtain the scale used, we divide the Radius in the drawing by the actual length :
1 9/16 ÷ 140
25 /16 ÷ 140
25 /16 * 1 /140
= 25 / 2240
= 5 /448
Hence, scale is 5 /448 times the actual length of drawing
Hence :
The scale used is :
1 feet = 7.4666 inches
Answer:
5/488

Answer:
B. Larger groups tended to take less time to solve the puzzle
Step-by-step explanation:
If you look at the graph, you can see that farther to the left the dots are higher, which means that the number of people are taking longer than the people to the right of the graph whose dots are lower, representing that it takes less time for the larger groups to solve the puzzle.
hope this helps youu
Each length of the side of square B is twice the length of the side of square A.
John says that this means the area of square B is twice the area of square A.
Is John right?
Justify your answer.
Answer:
yes
Step-by-step explanation:
because the area of square is l² so John is righrt
Answer:
Area of square= ²
Area of square A= ²
Area of square B = ?
let the length of square A = x
Area of square A =x²
then the length of square B = 2x
Area of square B =2x²
x²means area of square A
so Area of square B =2 times area of squarf A

prove that underroot 3-underroot 5 is irrational.
Please quickly I need this answer
Answer:
See Explanation
Step-by-step explanation:
Let us assume that [tex] \sqrt 3 - \sqrt 5[/tex] is a rational number.
So, it can be expressed in the form of [tex] \frac{p}{q} [/tex] where p and q are integers.
[tex]\therefore \sqrt 3 - \sqrt 5=\frac{p}{q}[/tex]
[tex]\therefore \sqrt 3 =\frac{p}{q}+ \sqrt 5[/tex]
[tex]\therefore \sqrt 3 =\frac{p+q\sqrt 5}{q}[/tex]
Squaring both sides:
[tex] (\sqrt 3) ^2 =\bigg(\frac{p+q\sqrt 5}{q}\bigg ) ^2 [/tex]
[tex]\therefore 3 =\frac{p^2 +5q^2 +2\sqrt 5 pq}{q^2 } [/tex]
[tex]\therefore 3q^2 ={p^2 +5q^2 +2\sqrt 5 pq}[/tex]
[tex]\therefore 0 = p^2 +5q^2 -3q^2 +2\sqrt 5 pq [/tex]
[tex]\therefore - 2\sqrt 5 pq=p^2 +2q^2 [/tex]
[tex]\therefore \sqrt 5 = \bigg (\frac{p^2 +2q^2}{-2pq} \bigg) [/tex]
[tex]\therefore \sqrt 5 = - \bigg(\frac{p^2 +2q^2}{2pq} \bigg) [/tex]
Since, p and q are integers so [tex] - \bigg(\frac{p^2 +2q^2}{2pq} \bigg) [/tex] is rational.
[tex]\therefore \sqrt 5 [/tex] is also rational.
But it contradicts the fact that [tex]\sqrt 5 [/tex] is irrational.
Hence, our assumption that [tex] \sqrt 3 - \sqrt 5[/tex] is rational is wrong.
[tex] \therefore \sqrt 3 - \sqrt 5[/tex] is irrational.
Rectangle JKLM
is rotated to obtain J′K′L′M′
. Which statement is true
a.J′K′L′M′ will be a quadrilateral but not a rectangle because the measurements of line segments and angles are preserved in a rotation, but parallel lines are not.
b.J′K′L′M′ will be a parallelogram but not a rectangle because parallel lines are preserved in a rotation, but the measurements of line segments and angles are not.
c.J′K′L′M′ will be a rectangle because the measurements of line segments and angles, and the presence of parallel lines are preserved in a rotation.
d. J′K′L′M′ will not be a rectangle because the measurements of line segments and angles, and the presence of parallel lines are not preserved in a rotation
Answer:
Answer is A - Angles that are congruent are complementary to the same angle.

Answer:
12 gallons
Step-by-step explanation:
If it takes 20 h for 5 gallons to be filled, it takes 4 h for 1 gallon to be filled. This is the ratio. You multiply 4 h by 12 to get 48 h, so you multiply 1 gallon by 12 as well. This is 12 gallons.
through: (-5, 4), slope =-3/5
Answer:
y - 4 = (-3/5)(x + 5)
Step-by-step explanation:
Use the point-slope formula y - k = m(x - h)
Here, y - 4 = (-3/5)(x + 5)

Jennifer's grandma bought her a $50 savings bond when she was born. When Jennifer is 30 years old, the bond will have earned 110% in interest. How much will the bond be worth when Jennifer is 30 years old?
Answer:
105$
Step-by-step explanation:
We are told that she starts with 50$
We are also that after 30 years she earns 110% on interest
Given this information we need to find the value of the bond after the 30 years
To do so we take 110% of the initial value (50$) and add that to the initial value
So the answer = 110%(50) + 50
110%*50=55
55+50=105
So in 30 years the bond will be worth 105$
