Answer:
EF = HG and EF || HG
Step-by-step explanation:
A quadrilateral is a polygon shape with four sides and four angles.
A parallelogram is a quadrilateral with two pairs of parallel sides. The following are properties of a parallelogram:
Opposite sides are equal and parallel.Opposite angles are equal to each other.Consecutive angles are supplementaryThe diagonals of a parallelogram bisect each other.If Quadrilateral EFGH with diagonals EG and HF is a parallelogram then EF = HG and EF || HG
A package designer wants the hexagonal base of a hat box to have an area of
about 200 in.2. About how long is each side?
Answer:
About 9inches long
Step-by-step explanation:
Area of a hexagon = 3√3/2 a²
a is the length of each side
Given
Area of the hexagon = 200in²
Substitute
200 = 3√3/2 a²
200×2 = 3√3 a²
400 = 3√3a²
a² = 400/3√3
a² = 400/5.196
a² = 76.982
a = √76.982
a = 8.774
Hence the length of each side is about 9inches long (to nearest inches)

Solve for x: 7x + 3 =2x +13
Answer:
x = 2
Step-by-step explanation:
7x + 3 = 2x + 13
Get all the x on the same side: 7x - 2x = 13 - 3
Subtract: 5x = 10
Divide both sides by 5 to get x = 2.
Plug the found value of x back in to check the answer: 7(2) + 3 = 2(2) + 13
Multiply: 14 + 3 = 4 + 13
Add: 17 = 17
This verifies that x = 2.
Step-by-step explanation:
[tex]7x+3=2x+13\\7x-2x=13-3\\5x=10\\x=2[/tex]

A bar graph titled Games per month has month on the x-axis and number of games on the y-axis. January has 7 games; February, 5 games; March, 3 games; April, 8 games; May, 6 games.
The bar graph shows the number of games a soccer team played each month. Use the data to find each listed value.
Median =
Lower quartile =
Upper quartile =
Interquartile range =
Median = 6, Lower quartile = 5; Upper quartile = 7; Interquartile range =2
What are Lower quartile and Upper quartile?The numbers that divide a piece of data into four equal portions are known as quartiles. A data set is divided in half by its median. The lower quartile (LQ) is the median value for the lowest half of a set of data. The upper quartile (UQ) is the median value for the higher half of a set of data.
Given data is:
7, 5, 3, 8, 6.
in ascending order the data is:
3, 5, 6, 7,8.
Hence, the median is = middle number from the data = 6.
The Lower quartile is =middle number from the lower part of the data = 5
The Upper quartile is = middle number from the data =7.
hence, the Interquartile range is = upper quartile - lower quartile
= 7 - 5
= 2.

Are the two expressions in the equation 2b + 5 + 1b = 3b + 5 equal or equivalent? How do you know
Given:
The expression is
[tex]2b+5+1b=3b+5[/tex]
To find:
Whether the two expression in the equation are equal or equivalent.
Solution:
If two expression are exactly the same, then they are equal and if the two expressions are different but the after simplification both are same, then they are called equivalent expressions.
We have,
[tex]2b+5+1b=3b+5[/tex]
Taking LHS, we get
[tex]LHS=2b+5+1b[/tex]
On combining liker terms, we get
[tex]LHS=(2b+1b)+5[/tex]
[tex]LHS=3b+5[/tex]
[tex]LHS=RHS[/tex]
In the given equation both expression are different but after simplification LHS = RHS, therefore the expression are equivalent not equal.

Answer:
(1) 1/8
(2) 1/12
(3) 1/16
(4) 1/20
Step-by-step explanation:
We need to find multiple divisions, it says 1/4 divided by 2 then go back to 1/4 and divide it again but by 3 then go back to it again and divide it by 4 then go back to 1/4 and divide it by 5.
We will take one by one
(1) 1/4 divides by 2 will be = 1/8
(2) 1/4 divided by 3 = 1/12
(3) 1/4 divided by 4 = 1/16
(4) 1/4 divided by 5 =1/20
These results are obtained by dividing the given parts, as the given Numerator is in fraction so whatever will be divided from the fractional numerator will get multiplied with the denominator.

Answer:
an american football field measures 100 yards long between the endzones,and is 53 1/3 yards wide.is the length of the diagonal across this field more or less than 120 yards . what is the value rounded to the nearest tenth of a yard
Step-by-step explanation:
To solve, you need to use Pythagorean Theorum
a^2+b^2=c^2
100^2+53.33^2 = c^2
10,000+2844.0889=c^2
12844.1=c^2
square root
= 113 1/3 yards
So it is less than 120 yards

Use the Law of Sines to write an expression that represents angle measure x.
Answer:
x° = arcsin(15.5/26.9×sin(73°))
Step-by-step explanation:
The law of sines tells you the sine of an angle is proportional to the length of the opposite side:
sin(x°)/15.5 = sin(73°)/26.9
sin(x°) = (15.5/26.9)sin(73°) . . . . . multiply by 15.5
Using the inverse function, we can find x.
x° = arcsin((15.5/26.9)sin(73°))

What is f(3) if f(x) = - 4x+1 ?
A.-44
B.-11
C. 1/2
D. 13
Please help me! :/
Answer:
Here is the equation:
f(x)=4x+1f(x)=4x+1
You need to find f(3). To do that, substitute all the x's with 3:
f(x)=4x+1 \rightarrow f(3)=4\times3 + 1f(x)=4x+1→f(3)=4×3+1
The first thing you need to do is multiply 4 by 3. Multiply:
4 \times 3 = 124×3=12
Here is your new equation:
f(3)=12+1f(3)=12+1
To get your answer, you need to add 12 and 1. Add:
12+1 = 1312+1=13
That means:
\bf f(3)=13f(3)=13

13 is the ans
