Step-by-step explanation:
14. The diagram in Fig. 1.34 shows a uniform metre rule
weighing 100 gf, pivoted at its centre 0. Two weights
150 gf and 250 gf hang from the points A and B
respectively of the metre rule such that OA = 40 cm
and OB = 20 cm. Calculate : (i) the total anticlockwise
moment about O, (ii) the total clockwise moment about
O, (iii) the difference of anticlockwise and clockwise
moments, and (iv) the distance from O where a 100 gf
weight should be placed to balance the metre rule.

150 gf
Fig. 1.34
250 gf
Answer:
(i) The total anticlockwise moment about O, is 6000 + 50 × OD
(ii) The total clockwise moment about O, is 5000 + 50 × OC
(iii) The difference between the anticlockwise and the clockwise moment is 1000 N·cm
(iv) The distance from O where a 100 gf force should be placed to balance the meter rule is 10 cm to the right of the point O on the meter rule
Step-by-step explanation:
The given parameters are;
The mass of the uniform meter rule = 100 gf
The center of the meter rule = O
The mass of the weight at point A = 150 gf
The mass of the weight at point B = 250 gf
The distance of the point A from the point O = OA = 40 cm
The distance of the point B from the point O = OB = 20 cm
(i) Whereby the point A is on the left of the meter rule, and taking the mass of half the meter rule as acting on the center, of the midspan from the left edge to the center, O, which is the point, D we have;
The total anticlockwise moment, Mₐ = 150 × 40 + 50 × OD = 6000 + 50 × OD
(ii) The total clockwise moment about O, is given similarly as follows;
The total clockwise moment, [tex]M_c[/tex] = 250 × 20 + 50 × OC = 5000 + 50 × OC
(iii) The difference between the anticlockwise and the clockwise moment = Mₐ - [tex]M_c[/tex] = 6000 + 50 × OD - 5000 + 50 × OC
Where, OD = OC, we have;
Mₐ - [tex]M_c[/tex] = 6000 + 50 × OD - 5000 + 50 × OD = 1,000
Mₐ - [tex]M_c[/tex] = 1000 N·cm
Therefore, Mₐ > [tex]M_c[/tex]
(iv) The distance from O where a 100 g force should be placed to balance the meter rule should give a 1000 N·cm clockwise moment as follows;
Let the 100 gf load be placed at the point E, to the right of the point O, therefore;
100 gf × OE = 1000 N·cm
OE = 1000/(100) = 10
OE = 10 cm
Therefore, the 100 gf should be placed 10 cm to the right of the point O.

Which equation has a graph that is a parabola with a vertex at (1,HI)?
Oy=(-12+1
O y--1-
O y=(«+ 1) +1
O y=x+1)-1
Answer:
[tex]y = (x +1)^2 - 1[/tex]
Step-by-step explanation:
Given
[tex]Vertex = (-1,-1)[/tex]
Required
Determine the equation
The equation of a graph from a vertex is:
[tex]y = a(x - h)^2 + k[/tex]
Where
[tex]a = 1[/tex]
[tex](h,k) = (-1,-1)[/tex]
Substitute these values in [tex]y = a(x - h)^2 + k[/tex]
[tex]y = 1(x - (-1))^2 + (-1)[/tex]
Express -(-1) as 1
[tex]y = 1(x +1)^2 + (-1)[/tex]
Express +(-1) as -1
[tex]y = 1(x +1)^2 - 1[/tex]
[tex]y = (x +1)^2 - 1[/tex]
Hence, the equation is:
[tex]y = (x +1)^2 - 1[/tex]

k/5 = 9/15 plz help mee
Answer:
k = 3
Step-by-step explanation:
Reduce the right side of the equation by 3 to get 3/5. Since both denominators now are even you should get 3 which is k as your answer.

Sharad went to his friend's place on a motorcycle. When he started, the reading was 19,235 km. When he reached his friend's place it was 19,301 km. How many km did sharad travel ?
Answer:
the number of km did sharad travel is 66 km
Step-by-step explanation:
The computation of the number of km did sharad travel is as follows:
= The km at his friend place - km when he started
= 19,301 km - 19,235 km
= 66 km
Hence, the number of km did sharad travel is 66 km
So, the same is to be considered by applying the given formula so that the correct distance could come

Ellen needs to make b batches of blueberry scones this weekend for her family's brunch party. She needs 2 cartons of blueberries for each batch, and each carton costs $4. Pick all the expressions that represent how much Ellen will spend on blueberries.
Answer:
Ellen will spend
$4(2b) on blueberries
Where b = number of batches of Blueberry scones she wants to make
Step-by-step explanation:
From the above question:.
Ellen needs to make b batches of blueberry scones this weekend for her family's brunch party.
Since she needs 2 cartons of blueberries for each batch, and each carton costs $4
1 batch = 2 cartons of blueberries
b batches =
Cross Multiply
b × 2 cartons
= 2b cartons of blueberries.
We also know that:
1 carton blueberries = $4
2b cartons of blueberries = x
Cross Multiply
x = 2b × $4
Therefore, Ellen will spend :
$4(2b) on blueberries

which has the least result? A. 3/4-3/4 B. 3/4+3/4 C. -3/4 + 3/4 D. -3/4-3/4?
Answer: D
Step-by-step explanation:
The solution to both A and C would total to about 0. Also, in B both numbers are positives, so that would also be out of the case. If you are looking for the least value, the answer would be D since -3/4 -3/4 would equal -1.5, (or -1 1/2). Therefore, your answer would be D.
Hope that helps :D
Answer:
D. -3/4 - 3/4
Step-by-step explanation:
A. 3/4 -3/4 = 0
B. 3/4 + 3/4 = 1 1/2
C. -3/4 + 3/4 = 0
D. -3/4 - 3/4 = -1 1/2

Seafoodgumbo,a traditional MardiGras dish, uses 12 cups of chicken broth for each 1 1/ 4 cups of flour. Mr. Clark used 8 3 /4 cups of flour for his gumbo.How many cups of chicken broth did he use?
Answer:
84 cups of chicken broth
Step-by-step explanation:
Ratio of chicken broth to flour = 12 cups : 1 1/4 cups
Mr. Clark used 8 3 /4 cups of flour for his gumbo.
How many cups of chicken broth did he use?
Let x = cups of chicken broth he used
Ratio of chicken broth to flour = x cups : 8 3/4 cups
Equate the ratios
12 cups : 1 1/4 cups = x cups : 8 3/4 cups
12 ÷ 5/4 = x ÷ 35 / 4
12 * 4/5 = x * 4/35
48 / 5 = 4x / 35
Cross product
48 * 35 = 5 * 4x
1,680 = 20x
x = 1,680 / 20
= 84
x = 84 cups
Katrina wants to build a fence around her Square Garden the garden has an area of 121 square feet How much Fencing will Katrina Need?
A. 13 Feet
B. 26 Feet
C. 39 Feet
D. 44 Feet
Answer:
The perimeter of the fencing is 44 feet (Option D)
Step-by-step explanation:
Area and Perimeter
A square shape of side length (a) has an area given by:
[tex]A = a^2[/tex]
And its perimeter is calculated as:
P = 4a
The area of Katrina's square garden is given as A=121 square feet. We need to calculate the side length by solving for a:
[tex]a=\sqrt{121}[/tex]
a = 11 feet
Once we know the value of a, then we calculate the perimeter:
P = 4*11 = 44
The perimeter of the fencing is 44 feet (Option D)
