What is the best approximation of 5/6 to the nearest hundreth.
Answer:
To find the percent, we first find the decimal.
To do that we divide 5 / 6, which gives us approximately 0.83333, now we multiply it by 100 since percentages are parts of 100.
0.83333 x 100 = 83.33%
Which of the following describes two triangles that are similar to one another?
We have to determine, which of the following triangle is similar to another one.
Two similar triangle are always congruent. Two figures are similar if they have the same shape and size.
Two triangles are similar if their corresponding sides are proportional. Two polygons are similar if their corresponding side are proportional.
If two angles and the included side of one triangle are equal to the corresponding angles and side of another triangle, the triangles are congruent.
Both triangles are similar by SSS theorem, because all three pairs are in proportion,
To calculate the proportion of sides,
Triangle 1; m1 = 67, m2 = 15Triangle 2 ; m1 = 15 , m2 = 95
[tex]\dfrac{67}{15}= \dfrac{15}{95}[/tex]
Thus the angles are not proportion then the triangle are not similar.
Triangle 1; m1 = 24, m2 = 101Triangle 2 ; m1 = 65, m2 = 101
[tex]\dfrac{24}{65}= \dfrac{101}{101}[/tex]
Thus the angles are not proportion then the triangle are not similar.
Triangle 1; m1 = 45, m2 = 80
Triangle 2 ; m1 = 59 , m2 = 45
[tex]\dfrac{45}{59}= \dfrac{80}{45}[/tex]
Thus the angles are not proportion then the triangle are not similar.
Triangle 1; m1 = 71, m2 = 32Triangle 2 ; m1 = 71 , m2 =77
[tex]\dfrac{71}{71}= \dfrac{32}{77}[/tex]
Thus the angles are in same proportion then the triangle are similar.

9.8x+17=7.6x-16
??????
Answer:
2.8867
Step-by-step explanation:
9.8x+17=7.6x-16
We move all terms to the left:
9.8x+17-(7.6x-16)=0
We get rid of parentheses
9.8x-7.6x+16+17=0
We add all the numbers together, and all the variables
2.2x+33=0
We move all terms containing x to the left, all other terms to the right
2.2x=-33
x=-33/2.2
x=-2.8867

A tropical species of mite named Archegozetes longisetosus is the record holder for the strongest insect in the world. It can lift up to 1.182 × 103 times its own weight. If a person who weighed 100 pounds were as strong as this insect, how much could that person lift? Enter the answer using scientific notation.
Answer:
The first thing we have to do is to measure your weight using a weighing scale.
Suppose your weight is 130 pounds, therefore you can lift:
130 pounds * 1.182 • 10^3 = = 153,660 pounds or 1.537 x 10^5 pounds

Tucker was asked to solve the equation 5x + 3 = 6x + 1. He did not know if his first step should be to add 5 negative x-tiles, or 1 negative unit tile, to both sides. What advice would you give Tucker to help him decide on his first step? Explain.
Answer: First Subtract 5x from both sides. Then subtract 1 from both sides.
Step-by-step explanation: To solve an equation, get all the variables (x, in this example) on one side and all the constants (numbers alone) on the other side of the equation.
The thing to remember about solving an equation is to keep it balanced. Do the same thing on both sides.
When possible, subtract smaller numbers from higher numbers.
5x + 3 = 6x + 1
5x -5x + 3= 6x - 5x + 1
5x-5x =0 on the left side so they "cancel" On the right, 6x-5x = x
3 = x + 1
3 -1 = x +1 -1
On the right 1-1 = 0 So the 1's "cancel" On the left 3-1 = 2
2 = x Rewrite as x = 2 to tell the solution

Jason is traveling by car from his home to his office. He has gone 3.5 miles so far. From this point on, he can cover 100 miles every 2 hours. What is the equation of a line that models the total miles traveled, y, in x hours after this point?
A.
y = 100x + 3.5
B.
y = 100x – 3.5
C.
y = 50x + 3.5
D.
y = -50x + 3.5
answer: 50x +3.5
Step-by-step explanation:
100 miles divided by 2 hours is 50 miles per hour, and he has already gone 3.5 miles, so the answer would be y= 50x +3.5

Find the measures of two supplementary angles if their measures are in the given ratio.
3:7
Two supplementary angles are in the ratio 3:7. Find the angles ?
Let the two angles be 3x and 7x.
Supplementary angles add up to 180 degrees.
Therefore:
3x + 7x = 180
10x = 180
x = 18
3x = 3 * 18 = 54
7x = 7 * 18 = 126
Measure of angles are 54° and 126°.
What is Supplementary angle?
Sum of two or more angles are 180 degrees then, the angles are called supplementary angle.
Given that;
The ratio of angles are 3 : 7.
Now,
Let the two angles be 3x and 7x.
Since, Supplementary angles are add up to 180 degrees.
So,
3x + 7x = 180
10x = 180
x = 18
So, First angle of supplemental angles = 3x
= 3 × 18
= 54
And, Second angle of supplemental angles = 7x
= 7 × 18
= 126
Thus, Measure of angles are 54° and 126°.

What is a unit rate?It is the quantity of an amount of something at a rate of one of another quantity.
In 2 hours, a man can walk for 6 miles
In 1 hour, a man will walk for 3 miles.
We have,
To find out how many pages each person reads in one hour, we can use the unit rate, the number of pages read per hour.
Jeff read 10(3/4) pages in 1/2 hour.
To find out how many pages he would read in one hour, we can multiply the number of pages he read by the fraction 2/1, which gives:
= 10(3/4) x 2/1
= 21 pages per hour
Jeff read 21 pages in one hour.
Kaley read 12(1/4) pages in 1/3 hour.
To find out how many pages she would read in one hour, we can multiply the number of pages she read by the fraction 3/1, which gives:
= 12(1/4) x 3/1
= 37 pages per hour
Kaley read 37 pages in one hour.
Nikkia read 13(1/2) pages in 3/5 hours.
To find out how many pages she would read in one hour, we can multiply the number of pages she read by the fraction 5/3, which gives:
= 13(1/2) x 5/3
= 22 pages per hour
Nikkia read 22 pages in one hour.
Thus,
Jeff read 21 pages in one hour, Kaley read 37 pages in one hour, and Nikkia read 22 pages in one hour.

What is the slope of this line? Enter your answer as a fraction in the simplest term in the box.
Answer:
-1/1
Step-by-step explanation:
The slope of a line is always the rise over run where rise is up or down(y axis) and the run is side to side(x-axis). Then, if the line is going up, your answer will be negative. So, using the points given, you can tell that the line is moving 2 units down while also moving 2 units to the left. Another way to calculate this is y2-y1 over(/) x2-x1, the y equals your y coordinates, x equals your x coordinants,d the 1 and 2 represent which points. Whichever point you use, you have to use the same coordinants fr the same value. For example, if you took the points (-2,0) and (0,-2) and you used (0,-2) as your second value, you can enter those into the formula.
(-2)-(0) / (0)-(-2) = -2 / 2
the denominater is a possitive two because, when you subtract a negative number, that number becomes positive and you now add it due to the distributive property. 0-(1)(-2) = -2 x -1 = 2

Given f(x) = 4x − 6 and g(x) = f(2x),
write an equation for g.
g(x) = _______________________
Answer:
1 and 1/3
Step-by-step explanation:
Fx equals 4x-6
Add six to both sides
6 equals 4X
Divide both sides by 4
2/3 equals x
Then GX equals f (2x)
Two times 2/3 is 1 and 1/3
The value of g(x) when f(x) = 4x − 6 and g(x) = f(2x) will be; 1/3
What is a function?Function is a type of relation, or rule, that maps one input to specific single output.
We have been given that f(x) = 4x − 6 and g(x) = f(2x), then;
We have to Add six to both sides;
f(x) = 4x − 6
6 = 4X
Now Divide both sides by 4;
2/3 = x
Then G(X ) is equals to f (2x)
Now, 2( 2/3 ) = 1 /3
The value of g(x) when f(x) = 4x − 6 and g(x) = f(2x) will be; 1/3
