Evaluate the expression when x = 1/4 and y = 1/2
2 (1/16 + x2) + 5y
Answer:
2 3/4
Step-by-step explanation:
x = 1/4
y = 1/2
so we have to plug in these numbers wherever we see x and y
2 (1/16 + (1/4)^2) + 5(1/2)
using pemdas we solve what's in the parenthesis first
(1/16 + (1/4)^2) = (1/8)
next is multiplication so
2 (1/8) = 1/4 and 5(1/2) = 5/2
lastly we add so
1/4 + 5/2 = 11/4 or 2 3/4

Identify the pairs of supplementary angles in the figure
Answer:
1st option is correct exactly
..............
A surveyor is standing 75 feet from the base of a building. The angle of elevation to the top of the building is 60°. Approximately how tall is the building? Round the answer tot he nearest tenth.
Using the principle of Pythagoras, the height of the building is approximately 129.9 feets.
Using SOHCAHTOA :
Tanθ = opposite / AdjacentTan(60) = height / 75
1.7320508 = height / 75
Height = 1.7320508 × 75
Height = 129.90 feets.
Hence, the height of the building is 129.9 feets.

In five to ten sentences, explain how the feudal system worked.Please write it in your own words and don’t copy off of internet my teacher will know easy if it is copied.
Answer:
Feudalism is a system of land ownership and duties. It was used in the Middle Ages. With feudalism, all the land in a kingdom was the king's. However, the king would give some of the land to the lords or nobles who fought for him, called vassals. The term feudal system is often used in a much more general way in political rhetoric to indicate an outdated, exploitative system of government.
Step-by-step explanation:
Hope it helps
Answer:
The feudal system was introduced to England following the invasion and conquest of the country by William I, The Conqueror. Feudalism did not always work as well in real life as it did in theory, and it caused many problems for society. The feudal system is a type of social and political system in which landholders provide land to tenants in exchange for their loyalty and service. The feudal systen developed because people needed prorection from invaders since the Roman Empire had fallen. The feudal system started at the top with the kimg granting his lamd to a baron for soldiers all the way down to a peasant getting land to grow crops.
(Fun fact: Another word for Feudal stsyem is feudalism)

Candace is designing a rectangular tile that has a width of 3/5 meter and an area of 9/10 meter what is the length of the tile Candace is designing
The length of the tile Candace is designing is 3 /2 meters.
The rectangular tiles he is designing has the following dimension:
width = 3/5 meters
area = 9/10 meters
The length of the tiles Candace is designing can be calculated below:
area of a rectangle = lw
where
l = length
w = width
Therefore,
9/10 = 3/5 l
cross multiply
9 × 5 = 3 × 10l
45 = 30l
divide both sides by 30
45 / 30 = l
l = 9 / 6 = 3 / 2 meters
length = 3 / 2 meters

Two sides of a parallelogram are 6.7 feet and 5.6 feet. The measure of the angle
between these sides is 152°. Find the area of the parallelogram to the nearest 10th of
a square foot.
Step-by-step explanation:
Area parallelogram = a×b×sin (x)
a, b = 6.7 ft and 5.6 ft
x = 152 degrees
so, we have
6.7×5.6×sin(152) = 37.52×sin(152) = 17.61457304... ft²
the rounded area is 17.6 ft².

Joakin lives 0.3 miles from Keith. Layla lives 0.4 times as far from Keith as Joakim. How far does Layla live from Keith. Write an expression to solve.
Answer:
0.12 Miles
Step-by-step explanation:
Given:
Joakin = 0.3 Miles from Keith
Layla lives 0.4 times as far as Joakim
Solution:
If Joakin lives 0.3 miles from keith and Layla lives 0.4 times as far from keith as Joakim that mean to multiply 0.3 by 0.4.
0.3 x 0.4 = 0.12
Hence, Layla live 0.12 Miles from Keith.

Step-by-step explanation:
because 7 goes into 35 and goes into 14 and goes into 28
Step-by-step explanation:
What is ratio for the geometric sequence?
U2 = 7
U1 = 35/2
r = U2 ÷ U1
r = 7 ÷ 35/2
r = 7 × 2/35
r = 1 × 2/5
ratio = 2/5 or 0,4
My friend has $280 to spend on a fence for her rectangular garden. She wants to use cedar fencing which costs $13/foot on one side, and cheaper metal fencing which costs $7/foot for the other three sides.
What are the dimensions of the garden with the largest area she can enclose?
length for cedar side = ___foot
width for other side = ___foot
What is the largest area that can be enclosed?
area = ____foot-squared
If necessary, round your answers accurate to two decimal places.
What are the dimensions of the garden with the largest area she can enclose?
The dimensions of the garden with the largest area she can enclose are length for cedar side = 7 foot and width for other side = 10 foot
Let L = length of the fence and W = width of the fence.
Also, let L be the length of cedar fencing.
Since we require one side of cedar fencing and the other 3 sides of cheaper metal fencing, and the cedar fencing costs $13/foot and the cheaper material costs $7/foot, the total cost of fencing is C = 13L + 7L + 2W × 7
= 13L + 7L + 14W
= 20L + 14W.
Since the total amount my friend wants to spend on fencing is $280, C = 280.
So, 20L + 14W = 280
10L + 7W = 140 (1)
Also, the area of the rectangular area is A = LW
From (1), L = (140 - 7W)/10
Substituting L into A, we have
A = LW
A = (140 - 7W)W/10
A = 14W - 0.7W²
To find the value of W that makes A maximum, we differentiate A with respect to W.
So, dA/dW = d(14W - 0.7W²)/dt
dA/dW = 14 - 1.4W
Equating it to zero, we have
14 - 1.4W = 0
14 = 1.4W
W = 14/1.4
W = 10 feet
To determine if this value maximizes A, we differentiate dA/dW with respect to W.
So, d²A/dW² = d(14 - 1.4W)/dW = -1.4
Since d²A/dW² = -1.4 < 0, W = 10 feet is a maximum point.
Since L = (140 - 7W)/10,
substituting W = 10 into the equation, we have
L = (140 - 7W)/10
L = (140 - 7 × 10)/10
L = (140 - 70)/10
L = 70/10
L = 7 feet
So, the dimensions of the garden with the largest area she can enclose are length for cedar side = 7 foot and width for other side = 10 foot
What is the largest area that can be enclosed?
The largest area that can be enclosed is area = 70 foot-squared
Since the area A = LW
Substituting the values of L and W into the e quation, we have
A = LW
A = 7 × 10
A = 70 ft²
So, the largest area that can be enclosed is area = 70 foot-squared
