The two figures are similar. Find the missing

Answers
Answer:
4 in
Step-by-step explanation:
For the smaller figure, we can assume the other missing side is 2 because the area is 4, and area = length*width.
So the area of the larger figure is 4^2, or 16, so then we can assume the x or the two missing sides for the larger figure are 4 beacuse 4*4=16

Step-by-step explanation:
[tex]36P^2-16M^2[/tex] can be factored using the "difference of squares" formula which is [tex]a^{2}-b^{2}=(a+b)(a-b)[/tex].
6*6=36 and 4*4=16; P*P=P^2 and M*M=M^2 -- from this we know that the two variables on each side of the minus sign are perfect squares. Now, see [tex]36P^2-16M^2[/tex] as [tex](6P)^2-(4M)^2[/tex] to make it fit nicer to the formula.
So, [tex](6P)^2-(4M)^2=(6P+4M)(6P-4M)[/tex].

Newton's Law of Cooling states that the rate of change of the temperature of an object, T, is proportional to the difference of T and the temperature of the region, TR or dT over dt equals k times the quantity T minus T sub R end quantity. An object with core temperature of 1200°F is removed from a fire and placed in a region with a constant temperature of 80°F. After 1 hour, its core temperature is 830°F. What is the object's core temperature 4 hours after it is taken off the fire?
Answers
Answer:
- 278.4°F
Step-by-step explanation:
Temperature of Object ( T ) = 1200° F
Temperature of surrounding ( M ) = 80°F
Time ( t ) = 1 hour
dT / dt ∝ ( M - T )
dT /dt ∝ | ( 80 - 1200 ) |
dT / dt = k ( 1120 )
(1200 - 830 ) / 1 = k ( 1120 )
hence k = ( 1200 - 830 ) / 1120
= 370 / 1120 = 0.33
what is the object's temperature (x )after 4 hours
( 1200 - x ) / 4 = 0.33 ( 1120 )
( 1200 - x ) / 4 = 369.6
hence x = 1200 - ( 4 * 369.6 )
= - 278.4 ° F

Answers
Answer:
235.3$ for part a
The amount in the account on April first of the following year is $3799.358 and the compound interest is $179.358.
What is Compound Interest?Compound interest is defined as the amount of interest which has been calculated on the principal amount as well as the amount accumulated over the previous period is also included.
(a) The amount in a compound interest can be found as,
A = P(1 + [tex]\frac{r}{n}[/tex]) ^(nt)
where A is the final amount, P is the initial or principal amount, r is the interest rate, n is the number of times compounding occurs in a year and t is the number of years.
Given P = $3,620, r = 6.5% = 0.065, t = 9 months = 0.75 year
n = 4 (since compounded quarterly)
A = 3620 (1 + [tex]\frac{0.065}{4}[/tex]) ^(4 × 0.75)
= 3620 (1.01625)³
= 3799.358
(b) Compound Interest = Final amount - Initial amount
= 3799.358 - 3,620
= $179.358
Hence the compound interest is $179.358.

When you are calculating the amount of mechanical energy used to exert force and move something, you are talking about work being done by a force at a distance. You can describe this in terms of foot-pounds. For example, you want to calculate the energy used to tighten a nut when using a wrench, or to lift a weight from the floor. Mechanical force takes place in time, so to describe the power requirement, you use foot-pounds per second.

Amanda pours 3/4 of her water into Barbara’s empty bottle. Barbara then pours 3/5 of her water into Charlie’s empty bottle. Charlie then pours 1/2 of his water into David’s empty bottle. If David now has 18 ounces of water, how many ounces does Amanda still have?
Answers
Answer:
8
Step-by-step explanation:
David=18
charlie pours 1/2 which is 18 because that is how many david has and 18 is half of charlies thing. So charli has 36 cause 18 times 2 is 36
CHARLI=36
36 is 3/5 of barbra's so 3 divided by 36 is 12 and ther are 2 more halfs so 12 times 2 is 24
BARBRA=24
24 is 3/4 of Amandas so you have to do 24 divided by 3 which is 8. so each 4th is 8 and there is one more 4th so it is 8
By: M
Division is defined as breaking down of larger quantity into smaller quantities equally. Vice versa, if we desire to calculate larger quantity on the basis of smaller quantities, we need to multiply the smaller quantity with their weights.
The quantity of water Amanda still have is [tex]20\: \rm ounces[/tex].
Solution:Given:
Quantity of water David has is [tex]18\: \rm ounces[/tex].
Quantity of water with David is 1/2 of water in Charlie's bottle.
Therefore quantity of water Charlie had is [tex]\rm 18 \times 2 \:ounces = 36\:ounces[/tex]
Quantity of water Charlie had is 3/5 of water in Barbara's bottle.
Therefore quantity of water Barbara had is [tex]36\times \dfrac{5}{3} = 60\rm \:ounces[/tex]
Quantity of water Barbara had is 3/4 of water in Amanda's bottle.
Therefore quantity of water Amanda had is [tex]60\times \dfrac{4}{3} \rm \:ounces = 80\: ounces[/tex].
Water left with Amanda:
[tex]1 - \dfrac{3}{4}=\dfrac{1}{4}[/tex] of total water i.e.
[tex]80\times \dfrac{1}{4}= 20\rm \:ounces[/tex]
