Answer:
27 11/4x
Step-by-step explanation:
First we add the similar parts of the expression.
Whole numbers
6 + 9 + 5 + 7 = 27
Then we add the fractions that dont have x.
We only add the numerators (2 and 3) and dont change the denominators (4)
2/4 + 3/4 = 5/4
Now we add the ones with x.
5/4 + 3/4x + 3/4x = 11/4x
Now we combine those parts together, making
27 11/4x

Solution
Let Y and Z be a.
Now,
90^0+Y+Z=180^0[sum of angle of a triangle is 180^0]
a+a=180^0-90^0
2a=90^0

The equation of a line is y = mx + b
Where m is the gradient/slope in this case 1/4 and b is the y-intercept in this case zero.
Based on that information we substitute it into the formula y = mx + b to get

Answers

6.25 seconds
At ground level the height of ball is 0, i.e., h=0.
Using zero product property, we get -16t -100

You have the diameter which is 2 times to radius. In order to get the radius you half the diameter which is 9.
9 to the second power is 81. Then you multiply it by the height which is 11. 81 x 11 is 891. So 891 x pi would be about 2799.16.
2r=d 2 r = d.
So plug in 18m in as d.
2r=18
/2 /2
r= 9
The volume of a cylinder is v= πr^2h
Use Pi symbol in calculator unless specified to use 3.14
The height is 11m
V=πr^2h
V= π(9)^2(11)
V= π(81)(11)
V= π(891)
V= 2,799.159054348506
So, to the nearest whole number: v= 2,800 m

3. The ______ projection shows the size and shape of continents accurately but distorts water areas.
A. Conic
B. Mercator
C. Robinson
D. Interrupted
Answers
The correct answer is A. Conic projection.
A conic projection is a type of map projection created by projecting the surface of a globe onto a cone. The cone is then unrolled and flattened to create a two-dimensional map. Conic projections are best for mapping small areas, such as individual countries or states. They are also good for mapping areas that are located near the equator.
Conic projections show the size and shape of continents accurately, but they distort water areas. This is because the cone is tangent to the globe at one point, and the further away from that point you get, the more distortion there is.
Mercator projection is a cylindrical map projection presented by Flemish geographer and cartographer Gerardus Mercator in 1569. It became the standard map projection for navigation because it is unique in representing north as up and south as down everywhere while preserving local directions and shapes. The map is thereby conformal. As a side effect, the Mercator projection inflates the size of objects away from the equator. This inflation is very small near the equator but accelerates with increasing latitude to become infinite at the poles.
Robinson projection is a map projection presented by American cartographer Arthur H. Robinson in 1963. It is a compromise projection that attempts to balance the distortions of area, shape, and distance. The Robinson projection is neither conformal nor equal-area, but it is pseudocylindrical, which means that the meridians are straight lines and the parallels are circles.
Interrupted projection is a type of map projection that is interrupted at regular intervals. This is done to reduce the distortion of the map. The most common type of interrupted projection is the Mercator projection, which is interrupted at the equator and the prime meridian
