Answer:
x = 4.5
Step-by-step explanation
When z is 6 that means x is 1.5 which means that when z is 18 then x is 4.5 because we add 3+1.5 which is 4.5

Now that you know the height of the cone how can you solve for the slant height?
Answer:
imagine a triangle
one side is just upwards trough the cone, one side is the radius of the circle and the last one is the slant height.
remember the pythagoras stuff
so
(slantheight)² = radius² + height²
or finally:
slantheight = squareroot (radius² + height²)
The graph of an absolute value function = a|x| includes the point (1,6). Complete the following statements. The value of a is ____
Answer:
6
Step-by-step explanation:
y = f(x)
6 = a |1 |
6 = a. 1
a = 6/1
a = 6
Answer:
[tex] \displaystyle a = 6[/tex]
Step-by-step explanation:
we are given a absolute value function
[tex] \displaystyle f(x) = a |x| [/tex]
we want to figure out the value of a
since we are a point which is on the function we can figure out a by using the point i.e (1,6) this point tell us when x is 1 f(x) is 6 thus
substitute:
[tex] \displaystyle 6= a \cdot |1| [/tex]
absolute value of any integer is positive therefore,
[tex] \displaystyle 6= a \cdot 1[/tex]
simplify multiplication:
[tex] \displaystyle 6= a [/tex]
hence,
the value of a is [tex]\underline{\quad 6 \quad}[/tex]

The half price of helium-5 is 7.6 X 10 to the power of negative 22 seconds and the half-life helium -9 is 7 x 10 to the power of negative 21-second approximately how many times greater is the half life of helium and -9 then that of helium -5
Answer:
Approximately 9.211 times
Step-by-step explanation:
Given
[tex]x = 7.6 * 10^{-22}s[/tex] --- half life of helium-5
[tex]y = 7 * 10^{-21}s[/tex] --- half life of helium-9
Required
How many times greater is y than x
To do this, we simply divide y by x
[tex]\frac{y}{x} = \frac{7 * 10^{-21}s}{7.6 * 10^{-22}s}[/tex]
[tex]\frac{y}{x} = \frac{7 * 10^{-21}}{7.6 * 10^{-22}}[/tex]
Apply law of indices
[tex]\frac{y}{x} = \frac{7 * 10^{-21--22}}{7.6}[/tex]
[tex]\frac{y}{x} = \frac{7 * 10^{-21+22}}{7.6}[/tex]
[tex]\frac{y}{x} = \frac{7 * 10}{7.6}[/tex]
[tex]\frac{y}{x} = \frac{70}{7.6}[/tex]
[tex]\frac{y}{x} = 9.211[/tex]

Parallelogram T U V S is shown. Angle U is (4 x + 9) degrees and angle V is (6 x minus 29) degrees.
Which angles equal 91°?
angles T and V
angles S and U
angles U and V
angles S and T
==========================================================
Explanation:
Angles U and V are adjacent angles since they are right next to each other in the letter sequence TUVS.
When dealing with parallelograms, adjacent angles are always supplementary (meaning they add to 180).
U+V = 180
(4x+9) + (6x-29) = 180
10x-20 = 180
10x = 180+20
10x = 200
x = 200/10
x = 20
Use this x value to find each angle mentioned
angle U = 4x+9 = 4*20+9 = 89 degreesangle V = 6x-29 = 6*20-29 = 91 degreesWe can see that U+V = 89+91 = 180 which helps confirm our answer so far.
Angle V is part of the answer we want. The angle opposite this is angle T.
We can identify a pair of opposite angles by looking at letters where they are separated by some other letter between them.
Opposite angles in a parallelogram are always the same measure. Both angles T and V are 91 degrees.
That means angles U and S are each 89 degrees.
Answer:
The answer is A- angles T and V

can someone help me identify c(6)=
Answer and Step-by-step explanation:
To solve, simply plug 6 in for m in the equation.
C(6) = 50(6) + 79.50
6 times 50 is 300.
300 + 79.50 = 379.50 = C(6)
The answer is 379.5
(Looking at the question again, I don't think what I said is what it is asking for, soo)
The slope of the function given represents the amount that needs to be paid every month. The y-intercept (79.50) represents the initial cost (starting amount) for paying the membership.

can someone please help me with this question
Answer:
15 kilometers
Step-by-step explanation:
So we know:
For 4 days she runs 1500 meters each day.
For 3 days she runs 3 kilometers each day.
First off, lets convert 1500 meters into kilometers.
There are 1000 meters in a kilometer, so pluggin in 1500 meters:
1500/1000 = 1.5
So for 4 days she runs 1.5 kilometers each day.
Now, to find the total kilometers, we must find multiply the 1.5 kilometers by the 4 days, the 3 kilometers by the 3 days, then add those two together.
So lets do this:
1.5*4 = 6
So she ran 6 kilometers in the first 4 days.
Next we have:
3*3 = 9
So she ran 9 kilometers in the last 3 days.
Now finally add them together:
6 + 9 = 15
So she ran a total of 15 kilometers.
Hope this helps!

a/b = a or b, depending what they give you
Answer:
45°
Step-by-step explanation:
This is a isosceles triangle and also a right triangle, so it means it have an 90° ingernal angle and the other two internal angles have the same value. Remember that the sum of the internal angles of a triangle is always 180°, so:
180° -90° = 90°
90°/2 = 45°

Answer:
Step-by-step explanation:
I'm assuming that you are solving for x, since there's nothing else you can do with this mathematically.
[tex]\frac{1}{2}x=-9[/tex] and the goal is to get the x all alone. So we have to lose the fraction. Do that by multiplying by the reciprocal of 1/2 which is 2/1 (a reciprocal is just a fraction flipped upside down). BUT...because this is an equation, what you do to the left side has to be done to the right side too. Like this:
[tex](\frac{2}{1})\frac{1}{2}x=\frac{-9}{1}(\frac{2}{1})[/tex]
On the left, everything cancels out but the x (which is why we do this), and on the right we multiply straight across the top and straight across the bottom to get
[tex]x=\frac{-18}{1}[/tex] which is
x = -18

A baseball is thrown into the air from the top of a 224-foot tall building. The baseball's approximate height over time can be represented by the quadratic equation h(t) = -16t2 + 80t + 224, where t represents the time in seconds that the baseball has been in the air and h(t) represents the baseball's height in feet. When factored, this equation is h(t) = -16(t - 7)(t + 2).
What is a reasonable time for it to take the baseball to land on the ground?
A.
5 seconds
B.
9 seconds
C.
2 seconds
D.
7 seconds
Answer:
D. 7s
Step-by-step explanation:
h(t) = height off the ground
We know the height of the ball at the point when it hits the ground will be 0, so we set h(t) = 0:
h(t) = -16(t - 7)(t + 2) = 0
In order for this to be true, either:
"t - 7 = 0" or "t + 2 = 0"
We can solve these to get the times at which the ball will hit the ground, which gives:
t = 7 or t = -2
-2s is not a logical time because the ball can't hit the ground before it is thrown so this solution is not relevant;
7s therefore is the correct solution
