use the formula for the area of a trapezoid A=h(b1+b2/2), were area is A b1 and b2 are the length of the base and h is the hight of 15yd. and the bases of 14yd.and 26yd
Answer: 300 yards
Step-by-step explanation:
Since b1 is equal to 14 yds and b2 is equal to 26 yds we can plug that into the equation below (in the image).
b1 + b2 = 14 + 26 = 40 yards
Now that we have found (b1 + b2), you can multiply that by h (the height of the trapezoid) which is 15, so we get 40 x 15 = 600.
In a lot of area equations, you will have to divide by two like in the trapezoid equation. Divide our number (600) by 2, so we get 600 ÷ 2 = 300.
300 yds is your final answer.

Solve the system: 4x - y = 5 x + 2y = 8
Answer:
x = 2y = 3Step-by-step explanation:
4x - y = 5..........… Equation 1
x + 2y = 8 ............. Equation 2
Make x the subject in equation 2 and substitute it into equation 1
That's
x = 8 - 2y
We have
4( 8 - 2y ) - y = 5
32 - 8y - y = 5
- 9y = - 27
Divide both sides by - 9
We have the final answer as
y = 3Substitute y = 3 into x = 8 - 2y
That's
x = 8 - 2(3)
= 8 - 6
x = 2Hope this helps you

Answer:
The center is ( 5.3, -3.3) and 7 is the radius
Step-by-step explanation:
We can write the equation of a circle as
( x-h)^2 + ( y-k)^2 = r^2
Where ( h,k) is the center and r is the radius
(x - 5.3)^2 + (y + 3.3)^2=49

NEED ANSWER ASAP!!!!! Find, to the nearest tenth, the area of the region that is inside the square and outside the circle. The circle has a diameter of 6 inches.
====================================================
Explanation:
See the diagram below. We're looking for the area of the shaded region in blue.
This is known as an inscribed circle since the circle is inside the square, touching each side at one point. This circle is as large as possible without spilling outside the square. Think of a balloon that has been inflated as much as possible to fill the room (it touches every wall at a tangent point).
The square has area s^2 = 6^2 = 6*6 = 36 square inches.
The circle has area pi*r^2 = pi*3^2 = 9pi square inches exactly. Note how I cut the diameter (6) in half to get the radius (3).
The blue shaded area is the difference of the square and circle areas, so we have 36 - 9pi as the exact area of the shaded region.
Using your calculator, you should find that 36-9pi = 7.72566611769187 approximately. I'm using my calculator's stored version of pi as opposed to something like pi = 3.14; but you may need to ask your teacher for clarification about what version of pi to use.
When rounding to the nearest tenth, we then get roughly 7.7 square inches as our final answer.
PLEASE HELP 15 POINTS + BRAINLIEST Find the coordinates of the other endpoint of the segment, given its midpoint and one endpoint. midpoint - (-15,22) endpoint- (-8,15) Please help oh and heres the hint included (Let (x,y) be the unknown endpoint. Apply the midpoint formula, and solve the two equations for x and y.)
FIRST TO ANSWER CORECTLY IS BRAINLIEST
Answer:
end point ₂ of a segment X₂ = - 22 ; Y₂ = 29
Step-by-step explanation:
given;
midpoint = ( Mx = - 15 , My = 22 )
endpoint ₁ = ( X₁ = - 8 , Y₁ = 15 )
find the other endpoint ₂ ( X₂ , Y₂)
use the mid point formula to get the other endpoint:
Mx = ( X₁ + X₂ ) / 2 My = ( Y₁ + Y₂ ) / 2
- 15 = (-8 + X₂) / 2 22 = (15 + Y₂) / 2
-30 = - 8 + X₂ 44 = 15 + Y₂
X₂ = -22 Y₂ = 29
Answer:
So, the formula for finding the midpoint of a segment given the coordinates of its endpoints is: ((x 1 + x2)/2, (y 1 + y 2 )/2 {Average of the x coordinates, average of the y coordinates}. For this problem we know the coordinates of the midpoint along with one of the endpoints.
Step-by-step explanation:
Use the midpoint formula
M = ( (x1 + x2) / 2 , (y1 + y2) / 2 )
(9, 0) = ( (x1 + 12) / 2 , (y1 + 3) / 2)
Break up this formula into two equations.
(x1 + 12) / 2 = 9 and (y1 + 3) / 2 = 0
Solve for x1 and y1 from the equations.

On average I sleep 7 hours and 45 minutes each day. Therefore, during one year I sleep for 7.45 x 365 = 2719.25 hours. Why is this calculation incorrect? And what is the correct answer?
Answer:
2830.6875 hours of sleep per year (7.45 should be 7.75)
Step-by-step explanation:
To find your average sleep per year, you need to covert avg hours per day, to days per year.
Note that 45 minutes is not equivalent to .45 hours, but actually .75 hours since there are only 60 minutes in an hour. ( 45 / 60 == .75 )
Simply, the amount of days per year is 365.25 (to account for leap years).
So perform this calculation:
(7.75 hrs / day ) * ( 365.25 days / year ) == 2830.6875 hrs / year
Meaning, on average you get 2830.6875 hours of sleep per year.
What did I do wrong, it says I'm wrong
Answer:
This is not a function.
Step-by-step explanation:
Note, that set A contains 3 elements that only map to 2 elements in set B. A function would require that each element of set A to match to only one element of set B.
Since set B contains an element with no mapping to an element in set A, this does not represent a function.
Which do you prefer: leaving √5 in radical form, or converting it to a decimal? Why? When would it be useful to use each?
Answer:
I prefer leaving the answer as √5 since it is a shorter form and exact form of the answer.
Here are reasons for leaving it as a radical form or a decimal approximation.
If you are looking for an exact answer, then you should leave it as √5. For example, if you are told a square has area 5 square units, then the exact length of the side is √5 units.
If √5 is the length of something that has to be made to that length, then you need an approximation. For example, if you are asked to make a square out of cardboard whose area is 5 square feet, then you need an approximation of √5 ft, such as 2.24 ft, so you can make each side of the cardboard square in the length of 2.24 ft.
We shall prefer to keep √5 in radical form, as it is an irrational number and will never give an exact value when converted to decimal form.
What are rational and irrational numbers?A rational number is any number that can be represented in the form p/q, where p and q are integers, q ≠ 0, and p, q are co-prime to each other, that is, they do not have any common factor except 1.
All terminating and non-terminating recurring decimals are rational numbers.
An irrational number is a real number that cannot be represented in the above form of a rational number.
All non-terminating non-recurring decimals are irrational numbers.
How do we solve the given question?We are asked, what would we prefer to do. Leave √5 in radical form or convert it into decimal form.
∵ √5 is an irrational number, we will never get a perfect value of it in decimal form, as irrational numbers are non-terminating non-recurring decimals. So, we shall prefer to keep √5 in the radical form.
Use of √5 in radical form: Gives the exact value in our calculations for equations.
Use of √5 = 2.236067977499........... in the decimal form: Used in trigonometry where we need to find the trigonometric ratio.

[tex] \therefore m\angle 1 = m\angle 2\\
\therefore 44x + 1 = 46x - 1\\
\therefore 1 + 1 = 46x - 44x\\
\therefore 2 = 2x\\
\therefore \frac{2}{2} = x \\

\therefore 12x - 11x = 6 - 2\\
\therefore x = 4\\
\because m\angle XVW = m\angle1 + m\angle 2\\
\therefore m\angle XVW = 12x + 2 + 11x +6\\

Answer:
Francis Drake was born in the UK and he's a naval officer
Step-by-step explanation:
Drake is most famously known for his circumnavigation of the world in a single expedition, from 1577 to 1580, and was the first to complete the voyage as captain while leading the expedition throughout the entire circumnavigation. He discovered that Tierra del Fuego, the land south of the Magellan Strait, was not another continent as Europeans believed, but instead a group of islands. This meant that ships could sail between the Atlantic and Pacific oceans around the bottom of South America (later known as the Cape Horn route).
