Answer:
2.4=x
Step-by-step explanation:
So, to solve this, we need to divide a length of one side of one shape by the length of the same side of the opposie shape.
We have several lengths we can use:
4.8 and 4 = 4.8/4= 1.2
3.6 and 3 = 3.6/3 = 1.2
6 and 5 = 6/5 = 1.2
So as we can see, the change or ratio between the two shapes is 1.2
Now lets multiply the 2 on the first shape by the 1.2 ratio to find the x value on the other shape:
2*1.2=2.4
So x=2.4
Hope this helps!

Explanation:
There's a lot to get lost in here, so I can see why it's intimidating. For me, it helps to focus on a few things at a time and try to build from there.
We only need 4 pieces of info to help find x. I'll circle what we need in the diagram below (see attached image). Note the color coding to see how the terms match up.
Since we have similar figures, the corresponding sides form proportional ratios. This means DE/ST is the exact same as EA/TP. I've indicated this in the diagram as well.
So that's why 2/x = 4/(4.8)
-----------------------
Let's solve for x in the equation below.
2/x = 4/(4.8)
2*4.8 = x*4 ... cross multiply
9.6 = 4x
4x = 9.6
x = (9.6)/4 .... divide both sides by 4
x = 2.4
Therefore, segment ST is 2.4 units long.
-------------------------
Side note: The decimal 2.4 converts to the improper fraction 12/5, which is equivalent to the mixed number 2 & 2/5.
Question:
A running club keeps track of the number of hours each person has trained for a race and the length of time it takes the person to run the race. A scatter plot is graphed with the x-axis indicating the number of hours a runner has trained and the y-axis indicating the time, in minutes, it took to run the race. The equation y = 60 - 0.5x is used as the line of best fit of the data. What does the slope of the equation represent?
options:
a
Runners will decrease their race time by 2 minutes for every 1 hour they have trained.
b
Runners will increase their race time by 2 minutes for every 1 hour they have trained.
c
Runners will increase their race time by 1 minute for every 2 hours they have trained.
d
Runners will decrease their race time by 1 minute for every 2 hours they have traine
The solution is, 60 minutes is a good prediction of how long it will take Tom to run the 6 mile race.
What is scatter plot?A scatter plot is a type of plot or mathematical diagram using Cartesian coordinates to display values for typically two variables for a set of data. If the points are coded, one additional variable can be displayed.
Here, we have,
We are given the scatter plot which shows the distance he has run and the time it took for each run.
We are asked to determine a good prediction of how long it will take Tom to run the 6 mile race?
One way to predict the time is by drawing a line that best fits the given data.
As you can see, from the line of best fit, the time corresponding to the 6 miles is around 60 minutes.
Therefore, 60 minutes is a good prediction of how long it will take Tom to run the 6 mile race.

How many millimeters are equal to one kilometer?
Metric
1 kilometer = 1,000 meters
1 meter = 100 centimeters
1 meter = 1000 millimeters
1 centimeter = 10 millimeters
Answer: The answer would be 1,000,000, or one million.
Step-by-step explanation:
There are 1000 millimeters in a meter, and there is the same number of meters in one kilometer. So to solve for how many millimeters are in one kilometer, just multiply 1000 by 1000 to get 1,000,000. Hope this helps!
A bullet of mass m1 = 0.020 kg is fired with initial speed v1 into a block of mass m2 = 0.500 kg that is initially at rest. The bullet becomes embedded in the block and the pair slide along to the right a distance d= 0.35 m over a rough surface with uk = 0.25. the spring (with k = 450 N/m) is compressed by a distance of x = 0.075 m. work backwards and determine the initial velocity of the bullet.
In the previous lesson, you created SMART goals for yourself to extend from the start of the semester to the end of the semester. This lesson introduced you to the various resources that are part of the course. How can these resources help you reach your goals?
Go back to your SMART goal chart from the previous lesson and alter one of the goals so that it incorporates the use of at least one resource.
Answer:
Improve your growth attitude, be more proactive, learn to understand yourself, be persistent despite hurdles, learn to accept your limits, learn how to make successful decisions, practice thankfulness, and stay open-minded to new opportunities are some of the ways that SMART goals can assist you.

Step-by-step explanation:
6. −7(x−6)=−70
7. Solve for n *(4 Points) 9+n=−2
Answer:
6. x = 16
7. n = -11
Step-by-step explanation:
6. -7(x-6)=-70
= -7x + 42 = - 70
= - 7x = - 70 - 42
= -7x = -112
= -7x/-7 = -112-/7
= x = 16.
7. 9 + n= - 2
= n= -2 - 9
= n = -11

Answer:
448
Step-by-step explanation:
I = Prt where I is the interest P is the principle r is the rate and t is the time
I = 400 * (.02) * 6
I = 48
The amount in the account is the interest plus the original amount
400 +48
448
Answer:
$ 448
Step-by-step explanation:
amount that Elena deposit (P) =$ 400
rate of interest (R)=2%
time (T)=6 years
formula to find interest is
Interest = PTR/100
=$400*6*2/100
=$4800/100
=$48
Total amout she receives after 6 years is
Amount = Interest + Principal
=$48 + $400
=$448

Using inverse operations is a direct way to solving equations
What is the Golden Rule for solving equations?
Answer:
Do unto one side of the equation, what you do to the other!
Step-by-step explanation:
An equation is like a balance scale. If we put something on, or take something off of one side, the scale (or equation) is unbalanced. When solving math equations, we must always keep the 'scale' (or equation) balanced so that both sides are ALWAYS equal.
Answer:
Keeping the equation balanced.
Step-by-step explanation:
You need to keep the equation balanced on both sides of the equal sign, like when you need to get rid of the number 4 on one side you have to do the same thing on the other side.

Answer:
9. y = 8
10. n = 21
11. 44 = v
12. c = 35
Step-by-step explanation:
9. 9y = 72
Divide each side by 9
9y/9 = 72/9
y = 8
10. 3n = 63
Divide each side by 3
3n/3 = 63/3
n = 21
11. 4 = v/11
Multiply each side by 11
4*11 = v/11*11
44 = v
12. c/7 = 5
Multiply each side by 7
c/7*7 = 5*7
c = 35

What is the area of the figure below?
Answer:
68 in
Step-by-step explanation:
Because the area of the squares is 3 x 3 = 9 and because there are two squares it is 18. The area of the central figure is 50 because i divided it into 4 triangles and 2 rectangles, each rectangle is 15 in and each triangle is 5 in so 15 x 2 = 30, 5 x 4 = 20 and 30 + 20 + 18 = 68
