Part D In her science class, Nadia needs to make a model showing the planets relative distance from the Sun. She wants to use centimeter grid paper to create her model. If 1 centimeter on the model represents 100,000,000 kilometers, write a proportion Nadia could use to create her model on the grid paper. Use the proportion to find the distance for each planet on the model. Then use a ruler and centimeter grid paper to draw a model similar to Nadia's.
Answer:
Mars
Step-by-step explanation:
100,000,000 kilometers, write a proportion Nadia could use to create her model on the grid paper. Use the proportion to find the distance for each planet on the model.
The quadratic function h(t) = −4.9t^2 + 50t + 2 represents the height, in meters, of a toy rocket t seconds after launch. How many seconds will it take the toy to reach the ground? State your answer to the nearest whole second.
Answer:
The toy reaches the ground in 10 sec
Step-by-step explanation:
When the rocket hits the ground, h becomes zero (0). Thus, our problem here is to solve the equation h(t) = −4.9t^2 + 50t + 2 = 0,
Because of the fractional coefficient -4.9, it's best to use the quadratic equation here. The coefficients of the t terms are {-4.9, 50, 2}. Thus,
the discriminant is b^2 - 4ac = 50² - 4(-4.9)(2) = 2539.2, and the square root of this is 50.39.
The quadratic formula is as follows:
-b ± √discriminant
t = -------------------------------
2a
which here is:
-50 ± 50.39
t = ------------------------ Since t represents time, only the positive result
-9.8 is relevant here; it is 10.24 sec,
which rounds off to 10 sec
The toy reaches the ground in 10 sec
Evaluate (-6/5 * 15/24) ÷ (7/9 x -1 17/18)
Answer:
243 /490 (Decimal: 0.495918)
Step-by-step explanation:
(-6/5 * 15/24) Simplified is -3/4
(7/9 x -1 17/18) Simplified is -1 83/162
So, -3/4 ÷ -1 83/162 = 243/490

Answer:
A
Step-by-step explanation:
V = (0.04)*H (Company P)
V = (0.06)*H (Company S)
V represents the vacation hours and H is the hours worked
If they both work 2080 hours
V1 = (0.04)*(2080) = 83.2 vacation hours (Company P)
V2 = (0.06)*(2080) = 124.8 vacation hours (Company S)
124.8 - 83.2 = 41.6 hrs

Answer:
C)
Step-by-step explanation:
First, multiply the 2 factors that add up to 8.
1/3 x 2. Since this equation does not have one x but 2 (x and y), we will not subtract or divide any sides.
Divide and multiply 2 by 8 and 1/3. Then, we solve for y.
y = 2/3x - 4

Find the Area of the shape
(Area of Composite Shapes)
Answer:
223.5 Km
Step-by-step explanation:
Area = Length x Width
Solving for Square Shape
8 · 6 = 48 km
Area = Length x Width
Solving for Rectangle Shape
9 · 14 = 126 km
Area = Length x Width ÷ 2
Solving for Triangle Shape
11 · 9 = 99 ÷ 2 = 49.5 Km
48 + 126 + 49.5 = 223.5 Km

The verticies of J’K’L would be, J'(-a, -b), K'(-c, -d), and L'(-e, -f).
What are transformations?Two-dimensional figures can be transformed mathematically in order to travel about a plane or coordinate system.
Dilation: The preimage is scaled up or down to create the image.
Reflection: The picture is a preimage that has been reversed.
Rotation: Around a given point, the preimage is rotated to create the final image.
Translation: The image is translated and moved a fixed amount from the preimage.
Given, Triangle JKL is rotated 180 about the origin, resulting in triangle J’K’L.
Assuming the coordinates of J(a, b), K(c, d) and L(e, f).
We know a rotation of 180° to (x , y) ⇒ (- x, - y).
Therefore, The vertices of J’K’L would be, J'(-a, -b), K'(-c, -d), and L'(-e, -f).

Answer:
it depends on the work place to play it safe i would choose 12
Step-by-step explanation:
The sample mean is equal to 24 and population mean is equal to 25
What is sample mean?Sample mean represents the measure of the center of the data. The sample mean formula is used to calculate the average value of the given sample data.
Sample mean= sum of the terms/number of the terms
What is population?
The population in static is used for a collection of data. The population mean can be calculated by the sum of all values in the given population divided by a total number of values in the given population.
Population mean= sum of the population/ number of the population
From the given question average of entire year is 25.
According to the population mean formula the sum of the population by number of the population is nothing but the average of the entire year. Thus the population mean is 25.
According to the sample mean formula,
sample mean= sum of the terms / number of the terms
⇒(25+10+16+39+27+25+32+25+25+22+28+14)/12 = 24
Thus the sample mean is equal to 24 and population mean is equal to 25
