Answers:
0.68
0.52
0.57
0.69
Answer:
3rd choice 0.57
Step-by-step explanation:
when rounding to the tenth place we look at the hundreds place and when it greater than or at 5 we round up and when it's less than 5 we round down.
1) explanation:0.7 when rounding to the tenth place. since the 8 was greater than 5 we round-up and get 0.70.
2)explanation: 0.5 when rounded to the tenth place the hundreds place which is 2 is less the 5 so we round down and get 0.50.
3)explanation: 0.6 when rounded its hundreds place is greater than 5 so we round up and get 0.60.
4)explanation: 0.7 when rounding to the tenth place. since the 9 was greater than 5 we round-up and get 0.70.

8x+2 factored using the GCF.
My friend is wondering this, I have seen responses but like all are different. Please help!
7th grade math.
Explanation:
For now, ignore the x.
The GCF of 8 and 2 is 2 since 2 is a factor of both
2 = 2*1
8 = 2*4
So if we had 8+2 we can factor 2 out like so to get 2*(4+1)
Notice that I divided each term by 2 when going from 8+2 to 4+1. Then I stuck a 2 outside. You can use the distributive property to check the result.
Similarly,
8x+2 = 2(4x+1)
which you can also check using the distributive property.

A town has a population of 2000 and grows at 4% every year. What will be the population after 15 years, to the nearest whole number? I just need the correct answer
Answer:
3200
Step-by-step explanation:
growth = current population + rate * time
= 2000 * .04 * 15
= 1200
original population + growth = total
2000 + 1200 = 3200

What would be the height of 1000 Canadian Dimes?
The height of 100 Canadian dimes is 1220 millimeter.
What is a expression? What is a mathematical equation? What is Equation Modelling?A mathematical expression is made up of terms (constants and variables) separated by mathematical operators. A mathematical equation is used to equate two expressions. Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.
We have 1000 Canadian dimes.
Assume that the height of 100 Canadian dimes is [x] mm. Then, we can write -
[x] = 1000 x 1.22
[x] = 1220 mm
Therefore, the height of 100 Canadian dimes is 1220 millimeter.

NATURE The frequency of a male cricket's chirp is related to the outdoor temperature. The

number of chirps the cricket makes in 14 seconds. Write an equation for the line in point-slope form.
PLEASE ANSWER I WILL DO ANYTHING I NEED THIS ASAP ITS DUE IN 3 MINUTES
above is the graph needed to answer this question
y−60=1(x−20) ,
y−40=x ,
y−50=1(x−10) ,
y−45=1(x−5) ,
or
y−55=1(x−15)
Step-by-step explanation: I have no idea
The equation for the graph written in point - slope form may be expressed thus y-60 = 1(x - 20)
The general form of a point - slope expression is :
y - y1 = m(x - x1) m = slopeTaking the pair of points (20, 60) :
x1 = 20 ; y1 = 60Slope = Rise / Run
Rise = (60 - 40) = 20Run = (20 - 0) = 20Slope = 20/20 = 1
Hence, the equation can be expressed thus by substituting the x1 and y1 values into the expression :
y - 60 = 1(x - 20)Therefore, the point - slope expression for the graph is y-60 = 1(x - 20).

The shortest side of a right triangle is 14 inches long. The difference between the lengths of the other two sides is 2 inches. Find the missing sides. Use exact values.
Answer:
The missing sides are 50 inches and 48 inches long.
Step-by-step explanation:
Let the lengths of the other two sides be x inches and y inches
And let x represent the length of the longest side.
From the question,
The difference between the lengths of the other two sides is 2 inches. That is,
x - y = 2 ...... (1)
The three sides of the right triangle are x, y, and 14 inches long.
From the Pythagorean theorem, " In a right triangle, the square of the longest side equals sum of squares of the other two sides"
Here, the longest side is x
Hence, we can write that
x² = y² + 14²
∴ x² = y² + 196 ...... (2)
Now, we have two equations, we can then solve simultaneously.
From equation (1)
x - y = 2
∴ x = y + 2 ...... (3)
Put this into equation (2)
x² = y² + 196
(y+2)² = y² + 196
y² + 4y + 4 = y² + 196
4y + 4 = 196
4y = 196 - 4
4y = 192
y = 192/4
y = 48
To determine x, we will substitute the value of y into equation (3)
x = y + 2
∴ x = 48 + 2
x = 50
Hence, x = 50 and y = 48
Since the lengths of the other two sides are x inches and y inches,
Hence, the missing sides are 50 inches and 48 inches.
Kiran has 10 1/2 feet of lumber and wants to make a bookshelfKiran needs two side panels that are each 5 2/3 feet. How much more lumber does Kiran need in order to make the side panels?
Total height of lumber, H = 10 1/2 feet = 21/2 feet .
Height of side panel, h = 5 2/3 feet = 17/3 feet .
Now,
Extra lumber required, L = 2 × Height of side panel - Total height of lumber
[tex]L=[2\times (\dfrac{17}{3})]-\dfrac{21}{2}\\\\L = \dfrac{5}{6}\ feet[/tex]
Therefore, extra lumber required is [tex]\dfrac{5}{6}[/tex] feet.
Hence, this is the required solution.
