Complete question
A stainless steel patio heater is a square pyramid. The length of one side of the base is 89.6 The slant height of the pyramid 90.1. What is the height of the pyramid?
To get the height of the pyramid, we will use pythagoras theorem.
slant height l is the hypotenuse
length of the base is the adjacent
height of the pyramid is the opposite
According to the theorem;
l² = h² + b²
90.1² = h² + 89.6²
8,118.01 = h²+8,028.16
h²= 8,118.01 - 8,028.16
h² = 89.85
h =√89.85
h = 9.48
Hence the height of the pyramid will be 9.48
Note that the value of the slant height was assumed to solve the problem.

Step-by-step explanation:
Answer:
d. 15 degrees
Step-by-step explanation:
You're basically trying to find angle DBC. Adding 115 and 50 will give you 165. This means that angle DBC must be 15, as the angles have to add up to 180. Angle 2 and angle DBC are equal, so angle 2 is 15 degrees.

Solve using elimination.
-4x + 7y = -1
6x - 7y = 5
Answers
Answer:
(4,-1)
Step-by-step explanation:
x is 4 y is -1
Answer:
(2,1)
Step-by-step explanation:
Let's solve your system by elimination.
6x−7y = 5;−4x+7y=−1
6x−7y=5
−4x+7y=−1
Add these equations to eliminate y:
2x = 4
Then solve2x = 4for x:
2x = 4
(Divide both sides by 2)
x = 2
Now let's plug x in to solve for y.
6x - 7y = 5
6(2) - 7y = 5
12 - 7y = 5
subtract 12 on both sides.
-7y = -7
divide both sides by -1
y = 1

The highest elevation in Delaware is 106 feet higher than the highest elevation in Florida. Louisiana's highest elevation is 190 feet higher than Florida's highest elevation. If you climbed from sea level to the highest points in Delaware, Florida, and Louisiana, you would only climb 1331 feet. How high is the highest elevation in each of the three states?
Answers
Answer:
Florida = 345 feets
Delaware = 451 feets
Louisiana = 535 feets
Step-by-step explanation:
Given that:
Let :
Highest elevation in Florida, = x
Highest elevation in Delaware = x + 106
Highest elevation in Louisiana = x + 190
Sum of highest elevation in the 3 states = 1331 feets
Hence,
x + x + 106 + x + 190 = 1331
3x + 296 = 1331
3x = 1331 - 296
3x = 1035 feets
x = 1035 / 3
x = 345 feets
Hence,
Highest elevation in Florida, = x = 345
Highest elevation in Delaware = 345 + 106 = 451
Highest elevation in Louisiana = 345 + 190 = 535

-6x + 8y = 18
They also tell us
3x = y, which is also y = 3x (just reversed)
So we take 3x and substitute it where we see y in the first equation, then solve for x
-6x + 8(3x) = 18
-6x + 24x = 18
18x = 18
x = 1
Then we solve for y
y = 3x
y = 3(1)
y = 3

Answer:
(x, y) = (-1, -3)
Step-by-step explanation:
You notice that the coefficient of x in the first equation is double the opposite of the coefficient of x in the second equation. This means we can make the x-term disappear by adding twice the second equation to the first.
(-6x +8y) +2(3x) = (-18) +2(y)
8y = -18 +2y . . . simplify
6y = -18 . . . . . . . subtract 2y
y = -3 . . . . . . . . . divide by 6
Substituting into the second equation, we have ...
3x = -3
x = -1 . . . . . . . . . divide by 3
The solution is (x, y) = (-1, -3).
Explain how we know that the sine of 270 degrees is -1. State one other value of θ such that sinθ=1.
Answers
Solution :
Trigonometry is that branch of mathematics which is used to study the relationship between the angles and the lengths of the sides of a triangle.
We known that the co-ordinate of a point on the circumference of a circle making an angle θ with the horizontal having a unit radius is given by :
(1 cos θ, 1 sin θ).
And for any angle made by sin θ on the x - axis is 0 and on the y -axis is 1 or -1 depending on the quadrant.
Since, angle 270 degree falls on the 3rd quadrant, therefore, the value of the co-ordinates of the point is (cos θ, sin θ) = (0,-1).
So the value of sin 270° = -1.
One other example of sin θ = 1 is 90° as 90 degree falls in the first quadrant.

Step-by-step explanation:
The y intercept will always be the number being added or subtracted from the independent variable.
The y intercept of y = 75x + 100 is 100, it means that the starting savings account balance is $100.
What is a linear equation?A linear equation is in the form:
y = mx + b
