A zoologist is recording the loss of wolves in her state. She notes the number of wolves, w, in the state on January 1. One year later, there were 84 wolves in the state, which is 23 fewer wolves than were in the state a year earlier. What is the number of wolves in the state on January 1?
Which equation can be used to find the number of wolves in the state on January 1?
w + 23 = 84
w−23=84
w−84=−23
23−w=84
Answers
Answer:
w+23=84 is the answer for that problem because in order to find the answer u need to do the opposite of subtraction
Answer:
w - 23 = 84
Step-by-step explanation:
W is the amount of wolves they had in the state for the first year. If 84 wolves is 23 less than what they had originally you would be subtracting that amount to get 84.

Answer:
16.8
Step-by-step explanation:
you get this by taking the ratio of 12:30 and applying it to 42
you get 30 by taking the total of 12 + 18
you then divide 12 / 30 which equals 0.4
you then multiply 0.4 * 42 which gives you 16.8
if you were to solve for the other ratio you would divide 18 / 30
and then take the answer of that, 0.6 and multiply it by 0.6 * 42
then you have the other part of the ratio.

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.

Answers
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.

Step-by-step explanation:
LCM is the lowest common multiple of two or more numbers.
To find it do that:
List the multiples of each numberFind the first common multiple of them, it will be the LCMLet us find the lowest common multiple of 4 and 7
→ List the multiples of 4
∵ The multiples of 4 are, 4, 8, 12, 16, 20, 24, 28, 32, 36, 40, .......
→ List the multiples of 7
∵ The multiples of 7 are, 7, 14, 21, 28, 35, 42, 49, .........
→ Find the first common multiple of 4 and 7
∵ 28 is the first common multiple of 4 and 7

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.

Answers
Let S=the amount of radium you start with
Let t=the amount of time in years
Let h=the half-life time
Then A=S(1/2)^(t/h)
So,
A=80(1/2)^(430/1690)
A=approx. 67g
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 ?
Answers
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.
Answers
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
