The weight of a full steel bead tire is approximately 800 grams, while a lighter wheel weighs only 700 grams. What is the weight of each tire in pounds? There are 453.592 grams in one pound. Round answers to 2 decimal places.
Answer:
1.54 and 1.7 I believe
Step-by-step explanation:
Answer:
The full steel tire is 1.76 pounds and the lighter wheel is 1.54 pounds
Step-by-step explanation:
To find how many pounds each tire is, divide the weight in grams by 453.592
Full steel tire:
800/453.592 = 1.76 pounds
Lighter wheel:
700/453.592 = 1.54 pounds
So, the full steel tire is 1.76 pounds and the lighter wheel is 1.54 pounds

A line segment has a length of approximately 10cm. If a compass is set to a width of 9cm, will it still be possibly to bisect the line segment?
Answer: Yes it is possible to bisect the given segment
The compass width (9) is over half of the segment length (10), so we can form the arcs needed to get the perpendicular bisector.

[tex] KS = 12 [/tex]
Step-by-step explanation:
Given that ∆KLM ~ ∆RSK, [tex] \frac{KL}{KR} = \frac{KM}{KS} [/tex] (similarity theorem)
KL = 65
KR = 65 - 52 = 13
KM = 60

Select the correct answer from each drop-down menu. Simplify. the square root of 64. I don't understand square root so if anyone could tell me how to do square root that would help.
Hey there! I'm happy to help!
Squaring a number is when you multiply it by itself. You represent this with an exponent, which is a little number above the number that you multiply by itself. When you square a number, this exponent is two.
1²=1
2²=4
3²=9
4²=16
5²=25
6²=36
7²=49
8²=64
9²=81
10²=100
The square root is basically just doing this backwards. It is finding the number that can be multiplied by itself to equal that number. You represent this with the √ symbol.
√1=1
√4=2
√9=3
√16=4
√25=5
√36=6
√49=7
√64=8
√81=9
√100=10
We know that 8 multiplied by itself is equal to 64. This means that the square root of 64 is 8.
I hope that this helps you out! Have a wonderful day! :D

Get average speed on the return journey in km/hr C. The total time taken for the whole journey in hrs. Good luck
Answer:
70 km/h

A box contains 10 transistors, 3 of which are defective. If 3 are selected at random, find the probability of the statements below. a. All are defective b. None are defective Answers has to be a fraction
Answer:
1. 1/120
2. 7/24
Step-by-step explanation:
n = 10
Number of defective = 3
1. Probability of all defective =
(Number of defective/n) x (number of defective -1/n -1)...(number of defective -n/n-1)
=3/10 x 2/9 X 1/8
= 6/720
= 1/120
2. probability of none defective
Since 3 are defective, those that are not defective = 7
The probability is therefore:
7/10 x 6/9 x 5/8
= 210/720
= 7/24.

the perimeter of a square ground is 128m
find it's area
Answer:
The answer is
1024 m²Step-by-step explanation:
Perimeter of a square = 4l
Area of a square = l²
where
l is the the length of one side
To find the area we must first find the length of the square using the perimeter
Perimeter = 128m
Substitute the value into the formula for finding the perimeter and find the length
That's
[tex]128 = 4l[/tex]
Divide both sides by 4
length = 32 m
So the area of the square is
A = 32²
We have the final answer as
Area = 1024 m²Hope this helps you
Katie walks 2 ft forward and 5 ft backwards. Find her displacement traveled.
Step-by-step explanation:
It is given that, Katie walks 2 ft forward and 5 ft backwards. We need to find her displacement traveled.
The difference between final position and the initial position is equal to displacement. It is the shorted path covered.
Let forward is +x and backward is -x
Initial position of Katie = +2 ft
Final position of Katie = -5 ft
Displacement = final position - initial position
= -5 - 2
Displacement = -7 ft
So, her displacement is 7 feet in backward direction.

Triangle ABC has vertices A(4, 5), B(0, 5), and C(3, –1). The triangle is translated 3 units to the left and 1 unit up. What are the coordinates of B' after the translation?
Answer:
[tex]B' = (-3,6)[/tex]
Step-by-step explanation:
Given
[tex]A(4,5)[/tex]
[tex]B(0,5)[/tex]
[tex]C(3,-1)[/tex]
Translation: 3 units left and 1 unit right
Required
Determine the new coordinates of B
Write out the coordinates of B
[tex]x = 0[/tex]
[tex]y = 5[/tex]
When a function is shifted to the left, we have to subtract the unit from the x value of the function;
Shifting by 3 units left, the new x becomes
[tex]New\ x = 0 - 3[/tex]
[tex]New\ x = -3[/tex]
When a function is shifted upward, we have to add the unit to the y value of the function;
Shifting by 1 unit up, the new y becomes
[tex]New\ y = 5 + 1[/tex]
[tex]New\ y = 6[/tex]
Hence, the new coordinates of B is
[tex]B' = (-3,6)[/tex]

ASAPPP How do I explain what's the difference in the meaning of the "+1" in the following equations: f(x)=2x^2+5x+1. and g(x)=2(x+5)^2+1 ??????
Answer:
The +1 in f(x) is the y intercept
The +1 in g(x) is the y coordinate of the vertex
Step-by-step explanation:
For f(x), plugging in x = 0 leads to
f(x) = 2x^2+5x+1
f(0) = 2(0)^2+5(0)+1
f(0) = 1
Showing that (0,1) is the y intercept of f(x).
The same is not true for g(x)
g(x) = 2(x+5)^2+1
g(0) = 2(0+5)^2+1
g(0) = 51
-------------------------------
The +1 for g(x) represents the y coordinate of the vertex. Recall that vertex form in general is
y = a(x-h)^2+k
with (h,k) being the vertex. This means we can quickly spot the vertex for g(x) without having to graph. The same cannot be said for f(x) as we need to complete the square to get f(x) into vertex form. Currently, f(x) is in standard form.

a pitcher can hold 8 times as much as a glass. the pitcher holds 64 ounces which model shows this comparison.
Answer:
A model that shows a pitcher holding 8 times the amount of a glass
Step-by-step explanation:
I would need a picture of the models, but I think I can still help.
Any model that shows a pitcher holding 8 times as much as a glass is the correct model. Be sure to read carefully so you pick the right model.
The equation y = 8x shows the relationship between the holding capacity of the pitcher and glass, and x = 64/8 shows the total amount held by the glass.
What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
Let's suppose the pitcher can hold x ounces
And the glass can hold y ounces
From the given problem:
y = 8x
The above equation modeled the relationship between the holding capacity of the pitcher and glass.
If y = 64
Then x = 64/8 = 8 ounces
Thus, the equation y = 8x shows the relationship between the holding capacity of the pitcher and glass, and x = 64/8 shows the total amount held by the glass.

Kim can mow the greens at the golf course twice as fast as I can. Working together, we can mow them in 4 hours. How long will it take me to mow the greens alone?
Answer:
12 hours
Step-by-step explanation:
Let x hours be the time it will take you to mow the greens at the golf course.
Since Kim can mow twice as fast, it will take Kim x / 2 hours to mow the greens.
In 1 hour, you will mow 1 / x of the greens
in 1 hour, Kim will mow 1 / (x / 2) of the greens= 2 / x of the greens
In 4 hours, you will mow 4 * 1 / x of the course = 4 / x of the greens
In 4 hours, Kim will mow 4 * 1 / (x / 2) of the course = 4 / (x / 2) = 8 / x of the greens.
Since we are dealing in fraction, the sum of the amount of greens that they would individually mow in 4 hours should be 1. i.e
(4 / x) + (8 / x) = 1
12 / x = 1
Solve for x;
x = 12
Therefore, it will take you 12 hours to mow the greens alone.
