Answer and Step-by-step explanation:
90ft = a
55ft = b
50ft = c
Plug into equation.
[tex]50^{2} = 90^{2} + 55^{2} - 2(90)(55)cosC\\\\2500 = 11125 - 9900(cosC)\\\\-8625 = -9900(cosC)\\\\0.8712 = cosC\\\\cos^{-1} (0.8712) = C\\\\29.4[/tex]

which is larger 4.5 or 9/2
Answer:
Both are equal
4.5 = 9/2
4.5 = 4.5
Hope it will help :)
Answer:
They are equal
Step-by-step explanation:
When we simplify 9/2 and divide, we get the answer 4.5, which is equal to 4.5. Therefore, neither number is larger and they are equal, just written in different ways.

what is f(-10)=
for what input is the output 93
a) replace x with -10 and solve:
-6(-10)-3 = 60-3 = 57
f(-10) = 57
b) replace f(x) with 93 and solve for x:
93 = -6x-3
Add 3 to each side:
96 = -6x

can you solve it using a method? and show work
Answer:
There are always three ways to solve a system of equationsThere are three ways to solve systems of linear equations: substitution, elimination, and graphing. Let's review the steps for each method.a book which cost 300 naira was sold for 240naira.what was the loss percentage?
Answer:
20%
Step-by-step explanation:
Since the original price of the book is 300 naira...
100% = 300 naira
1% = 300 ÷ 100 = 3 naira
240 ÷ 3 = 80
Since 80% is the percentage of the price after the loss..
100 - 80 = 20%
What is the value for x
What is the value for y
Answer:
y=155, x=65
Step-by-step explanation:
y+25=180
y=155
y=90+x
155=90+x
x=65
if my answer helped please mark as brainliest.
The required measure of angles x and y are 65° and 155° respectively.
Following the given figure, to determine the value of y and x.
In the figure angles y and 25° are supplementary angles, while x, 90°, and 25° are the angles of a triangle.
To determine y, follow the property of supplementary angle:
y + 25 = 180
y = 180 - 25
y = 155°
To determine x, follow the property of the triangle,
x + 90 + 25 = 180
x = 90 - 25
x = 65
Thus, the required measure of angles x and y are 65° and 155° respectively.

A ball is thrown into the air with an initial velocity of 30 meters per second.
The quadratic function h(t) = −4.9t^2 + 30t + 10 represents the height of
the ball above the ground, in meters, with respect to time t, in seconds.
Determine h(3) and explain what it represents.
Answer:
55.9
Step-by-step explanation:
The ball takes 3 seconds to go up 55.9 meters.
3^2=9
-4.9 x 9 = -44.1
30 x 3 = 90
-44.1 + 90 = 45.9
45.9 + 10 = 55.9

Daniel want to know the volume of his cube, he notices that the cube has 1/5 centimeters side length, what is the volume of the cube?
Answer:
1/125 cm^3
Step-by-step explanation:
Volume of a cube = L^3
L is the side length of the cube
Given
L = 1/5 cm
Volume of the cube = (1/5)^3
Volume of the cube = 1/125
Hence the volume of the cube is 1/125 cm^3

Answer:
[tex]\frac{49}{9}[/tex]
Step-by-step explanation:
Given
[tex](\frac{-3}{7})^{2!}[/tex]
Required
Determine the reciprocal
If a number is x, the reciprocal is: 1/x
So, the reciprocal of [tex](\frac{-3}{7})^{2!}[/tex] is:
[tex]\frac{1}{(\frac{-3}{7})^{2!}}[/tex]
[tex]2! = 2*1 =2[/tex]
So, we have:
[tex]\frac{1}{(\frac{-3}{7})^{2}}[/tex]
[tex]\frac{1}{(\frac{-3^{2}}{7^{2}})}[/tex]
Evaluate all exponents
[tex]\frac{1}{(\frac{9}{49})}[/tex]
Take inverse of 9/49
[tex]\frac{49}{9}[/tex]
Hence, the reciprocal of [tex](\frac{-3}{7})^{2!}[/tex] is [tex]\frac{49}{9}[/tex]
two step equations 12=18-d
Answer:
In this exercise, you need to get d:
12 = 18 - d
What we can do is substracting 18 in both sides:
12 - 18 = 18 - 18 - d
-6 = -d
And then, we can say that d = 6..
