Answer: 6%
Step-by-step explanation: Step 1: We make the assumption that 2000 is 100% since it is our output value.
Step 2: We next represent the value we seek with x.
Step 3: From step 1, it follows that 100%=2000$.
Step 4: In the same vein, x%=120.
Step 5: This gives us a pair of simple equations:
100%=2000(1).
x%=120(2).
Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS
(left hand side) of both equations have the same unit (%); we have
[tex]\frac{100\%}{x\%}=\frac{2000}{120}[/tex]
Step 7: Taking the inverse (or reciprocal) of both sides yields
[tex]\frac{x\%}{100\%}=\frac{120}{2000}[/tex]
[tex]\Rightarrow x=6\%[/tex]
Therefore, 120 is 6% of 2000$.

Please help. Find the area of the following shape
There are several ways to answer this. All involve finding a way to calculate the area of shapes we're familiar with and using those areas to find the area of this unusual shape. I've included three different ways, all of which yield the same total area.
In the first case, you cut the shape into two shapes by drawing a perpendicular line from point C to segment AE. That will give you a square and a trapezoid. The area of the square is (2 m)(5 m) = 10 m², and the area of the trapezoid is (0.5)(9 m - 5 m)(4 m + 4 m - 2 m) = 12 m². So the area of the entire shape is 10 m² + 12 m² = 22 m².
In the second case, you cut the shape into two shapes by drawing a perpendicular line from point C to segment AB. That will give you a rectangle and a triangle. The area of the rectangle is (2 m)(9 m) = 18 m². The area of the triangle is (0.5)(4 m - 2 m)(9 m - 5 m) = 4 m². So the area of the entire shape is 18 m² + 4 m² = 22 m².
In the third case, you can imagine that this shape is a piece of a larger rectangle with sides 4 m and 9 m with an area of 36 m². The area of this shape would be the difference between 36 m² and the area of the imaginary trapezoid that fills in rest of the rectangle. That trapezoid would have an area of (0.5)(4 m - 2 m)(9 m + 5 m) = 14 m². So the area of the shape given would be 36 m² - 14 m² = 22 m².
In any case, the area of the shape is 22 m².

Answer:
Step-by-step explanation:
9.1 h + 11.6 t = 9.98(60)
9.1 h + 11.6 t = 598.8 ........ (1)
h + t = 60 ........ (2)
h = 60 - t
9.1(60 - t) + 11.6 t = 598.8
546 - 9.1 t + 11.6 t = 598.8
2.5 t = 52.8
t = 52.8 ÷ 2.5 = 21.12 ≈ 21 (lb.)
h = 60 - 21.12 = 38.88 ≈ 39 (lb.)

A pizza is removed from the oven at a temperature of 425 F. After 15 minutes, the pizza has
cooled to 200°F. Use a continuous exponential decay model to find the approximate decay
rate.
WILL MARK BRAINLIEST!! 20 POINTS!
Answer:
The decay rate is of 0.05 = 5% per minute.
Step-by-step explanation:
Continuous exponential decay model:
The exponential equation of decay for an amount, after t units of time, is given by:
[tex]A(t) = A(0)e^{-rt}[/tex]
In which A(0) is the initial amount, e(approx 2.72) is the Euler value and r is the decay rate, as a decimal.
A pizza is removed from the oven at a temperature of 425 F.
This means that [tex]A(0) = 425[/tex]
After 15 minutes, the pizza has cooled to 200°F.
This means that [tex]A(15) = 200[/tex], that is, when [tex]t = 15, A(t) = 200[/tex]
We use this to find r.
[tex]A(t) = A(0)e^{-rt}[/tex]
[tex]200 = 425e^{-15r}[/tex]
[tex]e^{-15r} = \frac{200}{425}[/tex]
[tex]\ln{e^{-15r}} = \ln{\frac{200}{425}}[/tex]
[tex]-15r = \ln{\frac{200}{425}}[/tex]
[tex]r = -\frac{\ln{\frac{200}{425}}}{15}[/tex]
[tex]r = 0.05[/tex]
The decay rate is of 0.05 = 5% per minute.

On this necklace the ratio of black beads to white beads is 1:4
How many more black beads do you need to
add to make the ratio of black to white 4:1 ?
Answer:
16
Step-by-step explanation:
This is because the ratio of black to white can be set up as 1/4, for every one black bead there is 4 white so what is 1/4x that equals 4? simple, x=16 because 16/4 equals to 4 so it would be 4 black beads to 1 white bead.

A cylindrical can of popped corn has a lateral surface area of 6760 T
cm? The height of the can is 40 cm. Using your formula chart, find the
correct formula and use it to find the radius.
F. 168 cm
H. 13 cm
G. 84.5 cm
J. 26 cm
9514 1404 393
Answer:
G. 84.5 cm
Step-by-step explanation:
Assuming the lateral area is 6760π cm², we can find the height from ...
A = 2πrh
r = A/(2πh) = (6760π cm²)/(2π·40 cm) 6760/80 cm = 84.5 cm
The radius of the can is 84.5 cm.

How can the product of 5 and 0.3 be determined using this number line? Number line from 0 to 2.0 with tick marks at every tenth. An arrow goes from 0 to 0.3. Enter your answers in the boxes. Make_____ jumps that are each_____unit long. You end at______ , which is the product of 5 and 0.3.
Answer:
5 0.3 1.5
Step-by-step explanation:
you count by 3
To determine the product of 5 and 0.3 using the number line described, make 5 jumps that are each 0.3 units long, you end up at 1.5.
Since the distance between each consecutive tick marks is 0.3 ; we only need to jump 5 times starting from the 0 towards the right. Hence, jumping five times towards the right by a distance of 0.3 each time gives a value of 1.5 on the final or end point which is also the product of 0.3 × 5Learn more :https://brainly.com/question/18112348

Step-by-step explanation:
Acvording to the intersecting chord theorem, the products of the line segments formed are equal to each other.
Therefore:
5*x = 10*6
5x = 60
Divide both sides by 5
5x/5 = 60/5
x = 12
