Answer:
Given,
mass of snow flake = 2 kg
mass of midnight = 997 gm
Now,
1 kg = 1000 gm
2 kg = 1000 * 2
= 2000 gm
therefore the difference between the masses of the kittens = 2000
- 997
= 1003 gm (is the answer)

A label prints in the pediatric pharmacy
satellite for 500 mL of dextrose 15% solu-
tion. This concentration is not available
commercially and needs to be compound-
ed. Available in your pharmacy, you have
a 1 L bag of sterile water and a 1 L bag
of dextrose 70% available to compound
the solution. How many mLs of each are
needed to make the requested solution?
Answer:
107.14 ml of 70% dextrose and 392.86 ml of sterile water should be used.
Step-by-step explanation:
Since a label prints in the pediatric pharmacy satellite for 500 mL of dextrose 15% solution, but this concentration is not available commercially and needs to be compounded, and available in your pharmacy, you have a 1 L bag of sterile water and a 1 L bag of dextrose 70% available to compound the solution, to determine how many mLs of each are needed to make the requested solution, the following calculation must be performed:
500 x 0.15 = 75
100 x 0.70 = 70
A x 0.70 = 75
A = 75 / 0.70
A = 107.14
Therefore, 107.14 ml of 70% dextrose and 392.86 ml of sterile water should be used.

a rice cooker was sold for $60 after a discount of 60% waht was the usual price of the rice cooker with explaination simple method for class 5
Answer:
$150
Step-by-step explanation:
So, 60 dollars is 40% of the original price. So 30 dollars is 20% of the original price, and 150 dollars is 100% of the original price. So, the original value of the rice cooker is 150 dollars.
Answer:
The price of the Rice Cooker was 150$.

Matt and his brother will each work 13 hours this week for their dad. If Matt earns $14.00 an hour and his brother earns $17.00 an hour, how much will Matt earn by the end of the week? *
Answer:
$182.00
Step-by-step explanation:
We know that Matt will work for 13 hours, and that he will earn 14.00 an hour. We are asked how much Matt will earn by the end of the week. Because Matt's earnings are not based on his brother's earnings, we can disregard how much his brother makes.
We add 14.00 13 times, as Matt earns 14 dollars for each hour and he works for 13 dollars. This is equal to multiplying 14 by 13, resulting in 14 * 13 = 182 as our answer

Extreme 2: <13, 15> SHOW YOUR WORK!!!!
Answer:
See below
Step-by-step explanation:
3. What are two ways that a vector can be represented?
Considering a vector [tex]\vec{v}[/tex] in some vector space [tex]\mathbb R^n[/tex] we have
[tex]\vec{v} = \langle a,b\rangle[/tex]
This is the component form. I don't like that way. It is probably used in high school, but
[tex]\vec{v} = \begin{pmatrix} a\\ b\\ \end{pmatrix}[/tex]
is preferable because the inner product on [tex]\mathbb R^n[/tex] is defined to be
[tex]$\langle a,b\rangle := \sum_{i = 1}^n a_i b_i$[/tex]
You can also write it using linear form such as [tex]\vec{v} = 2i+2j[/tex]
4.
For this question, I think you meant
vectors
[tex]\vec{u_1} = (-8, 12)[/tex]
[tex]\vec{u_2} = (13, 15)[/tex]
Once
[tex]\cos(\theta)=\dfrac{\vec{u_1} \cdot\vec{u_2}}{||\vec{u_1}||||\vec{u_2}||}[/tex]
Considering that the dot product is
[tex]\vec{u_1}\cdot \vec{u_2} = (-8)\cdot 13 + 12\cdot 15 = -104+180= 76[/tex]
and the norm of [tex]\vec{u_1}[/tex] is [tex]||\vec{u_1}|| = \sqrt{(-8)^2 + 12^2} = \sqrt{64 + 144}= \sqrt{208}[/tex]
and the norm of [tex]\vec{u_2}[/tex] is [tex]||\vec{u_2}|| = \sqrt{13^2 + 15^2} = \sqrt{169 + 225}= \sqrt{394}[/tex]
Thus,
[tex]\cos(\theta)=\dfrac{76}{\sqrt{208} \sqrt{394}} = \dfrac{19}{\sqrt{13}\sqrt{394}}=\dfrac{19}{\sqrt{5122}}[/tex]
[tex]\therefore \theta = \arccos \left(\dfrac{19}{\sqrt{5122}} \right)[/tex]

Add 1/4 + 5/14 +6/7 Simplify the answer and write it as a mixed number.
Answer:
[tex]\frac{41}{28}[/tex] = [tex]1\frac{13}{28}[/tex]
Step-by-step explanation:
In order to add fractions, the denominators must all be the same value (the lowest common denominator). The lowest common denominator is the smallest value that all of the given denominators (in this case, the denominators are 4, 14, and 7) can divide into.
Here, the smallest number that all three of the given denominators can perfectly divide into is 28:
28 ÷ 4 = 7
28 ÷ 14 = 2
28 ÷ 7 = 4
Therefore, our lowest common denominator is 28.
The next step is to change our numerators to match our lowest common denominator. To do this, we have to multiply the numerator by the same value that we would need to multiple the denominator by in order to get our lowest common denominator.
For our first term of 1/4, we need to multiply our denominator (4) by 7 in order to get our lowest common denominator of 28. So, we need to also multiply our numerator by 7:
[tex]\frac{1}{4}[/tex] × [tex]\frac{7}{7}[/tex] = [tex]\frac{7}{28}[/tex]
Therefore, our first term becomes [tex]\frac{7}{28}[/tex].
For our second term of 5/14, we need to multiply our denominator (14) by 2. So, we need to also multiply our numerator by 2:
[tex]\frac{5}{14}[/tex] × [tex]\frac{2}{2}[/tex] = [tex]\frac{10}{28}[/tex]
Therefore, our second term becomes [tex]\frac{10}{28}[/tex].
For our third term of 6/7, we need to multiply our denominator (7) by 4. So, we need to also multiply our numerator by 4:
[tex]\frac{6}{7}[/tex] × [tex]\frac{4}{4}[/tex] = [tex]\frac{24}{28}[/tex]
Therefore, our third term becomes [tex]\frac{24}{28}[/tex].
Now that they all have the same denominator, we simply have to add all three together:
[tex]\frac{7}{28}[/tex] + [tex]\frac{10}{28}[/tex] + [tex]\frac{24}{28}[/tex] = [tex]\frac{41}{28}[/tex]
When we simplify this into a mixed number, we get:
[tex]\frac{41}{28}[/tex] = [tex]1\frac{13}{28}[/tex]

41/28 = 1 (13/28)

Start with the first two columns, taking every possible pair of True/False for p and q.
¬q is just the negation of q, so True becomes False and False becomes True.
p ∨ q is the logical disjunction, or logical "or". It's True if either p or q is True, and False otherwise. So p ∨ ¬q is True only if either p or ¬q is True.
p ⇒ q is the logical implication. It's True only when both p and q are True, or when p is False. So (p ∨ ¬q) ⇒ q is True when both p ∨ ¬q and q are True, or when p ∨ ¬q is False.

[tex]f(x)=\dfrac{5-x}{x^2+5x+6}[/tex]
To find:
The points on the graph at the function value [tex]f(x)=3[/tex].
Solution:
We have,
[tex]f(x)=\dfrac{5-x}{x^2+5x+6}[/tex]
Substituting [tex]f(x)=3[/tex], we get
[tex]3=\dfrac{5-x}{x^2+5x+6}[/tex]
[tex]3(x^2+5x+6)=5-x[/tex]

questions tell you about him?
One loaf of bread and six rolls cost $1.80. At the same prices, two loaves of bread and four rolls cost $2.40. How much does one loaf of bread cost. I have go the answer which is 90 cents and one roll costs 15 cents but the math Olympiad book solution does not explain it well can someone explain it better?
9514 1404 393
Answer:
loaf: $0.90; roll: $0.15
Step-by-step explanation:
Let b and r represent the cost of a loaf of bread and a roll, respectively.
The two purchases can be written in equation form as ...
b +6r = 1.80
2b +4r = 2.40
__
The usual ways to work problems like this are "substitution" or "elimination". The latter is sometimes called "addition."
SubstitutionThe way these equations are written, we can see that it is relatively easy to write an expression for b from the first equation:
b = 1.80 -6r
Substituting that into the second equation, we get ...
2(1.80 -6r) +4r = 2.40
3.60 -8r = 2.40 . . . . . . . collect terms
1.20 = 8r . . . . . . . . . . add 8r-2.40
0.15 = r . . . . . . . . . divide by 8
Then substituting this into the expression for b, we have ...
b = 1.80 -6r = 1.80 -6(0.15) = 0.90
One loaf costs $0.90; one roll costs $0.15.
__
EliminationThe idea with "elimination" is to combine the equations in such a way that one of the variables is eliminated in the process. Here, there are several ways that can be done.
We recognize that the b-coefficient in the second equation is double that in the first equation. So, we can subtract the second equation from double the first equation to make the b-terms disappear.
2(b +6r) -(2b +4r) = 2(1.80) -(2.40)
8r = 1.20 . . . . . . . simplify
r = 0.15 . . . . . . . divide by 8
Using the first equation, we can find b:
b + 6(0.15) = 1.80
b = 0.90 . . . . . . . . . subtract 0.90
One loaf costs $0.90; one roll costs $0.15.
__
Another way we can eliminate one of the variables is to rewrite the second equation without its excess factor of 2:
b +2r = 1.20
Then subtracting the first equation from 3 times this will eliminate the r variable:
3(b +2r) -(b +6r) = 3(1.20) -(1.80)
2b = 1.80 . . . . . . . . . simplify
b = 0.90
Then, using the above version of the second equation, we have ...
0.90 +2r = 1.20
2r = 0.30
r = 0.15
One loaf costs $0.90; one roll costs $0.15.
Betty received $ 500,000 from a life insurance policy to be distributed to her as an annuity certain in 10 equal annual installments with the first payment made immediately. On the day she receives her third payment, she is offered a monthly perpetuity of X in lieu of the future annual payments. The first payment will be made in exactly one month. The effective annual rate of interest is 8 %. Determine the value of X.
9514 1404 393
Answer:
annual payment: $68,995.13monthly payment in perpetuity: X = $2394.76Step-by-step explanation:
a) For payments made at the beginning of the period, the annuity is called an "annuity due." The formula in the first attachment tells how to compute the payment for a given present value ($500,000), number of periods (N=10), and interest rate (i=0.08).
pmt = $500,000/(1 +(1 -(1 +i)^(-N+1))/i) = $500,000/(1 +(1 -(1.08^-9))/.08)
pmt ≈ $68,995.13 . . . . annual payment
__
b) After the first payment, the account balance is ...
$500,000 -68,995.13 = $431,004.87
After subsequent payments, the account balance will be ...
$431,004.87×1.08 -68,995.13 = $396,490.13 . . . after 2nd payment
$396,490.13×1.08 -68,995.13 = $359,214.21 . . . after 3rd payment
The payment amount that can be made in perpetuity is the amount of the monthly interest on this balance:
X = $359,214.21 × (0.08/12) = $2394.76
