We are trying to find the new temperature. We can disregard time since we are not asking for the time elapsed but for the change in temperature.
Our starting temperature is -17 °F and rose by 23 °F:

Answer:
3 hours
Step-by-step explanation:
If both the cars are moving in the same direction,
Speed of orange sports car = 60 miles per hour
Since, this car has already moved for 1 hour,
Distance covered by the sports car = speed × time
= 60 × 1
= 60 miles
Speed of the green van = 30 miles per hour
Since, green van has already moved for the duration = 3 hours
Distance covered by the green van = speed × time
= 40 × 3
= 120 miles
Therefore, distance between sports car and green van = 120 - 60
= 60 miles
Relative speed of orange sports car with respect to green van = Speed of sports car - speed of green van
= 60 - 40
= 20 miles per hour
Time taken by the orange sports car to cover 60 miles (Distance between sports car and green van) = [tex]\frac{\text{Distance between the car and van}}{\text{Relative speed of the sports car}}[/tex]
= [tex]\frac{60}{20}[/tex]
= 3 hours
Therefore, orange sports car will take 3 hours to pass the green mini green van.

james ran 25/100 of a mile yesterday and his friend Natasha ran 4/10 of a mile. who ran farther and how do u know
Answer: Natasha ran further
Step-by-step explanation:
1. Simplify both fractions into a common denominator:
25/100 and 40/100
2. Compare:
40/100 > 25/100
3. Answer:
Natsha ran further
Have a nice day! :D
Answer:
Natasha ran farther
Step-by-step explanation:
This is the answer because:
1) In problems like this, we have to find the common denominator and compare both of the fractions:
[tex]\frac{4}{10} = \frac{4 times10}{10 times 10} = \frac{40}{100}[/tex]
[tex]\frac{40}{100}[/tex] > [tex]\frac{25}{100}[/tex] = 40/100 is greater than 25/100.
Therefore, the answer is Natasha.
Hope this helps! :D
If a radioactive isotope has a half-life of 6 hours and 12 milligrams is initially present, how much will
be present in 24 hours?
Answer:0.75 milligrams will be present in 24 hours
Step-by-step explanation:
Step 1
The formula for radioactive decay can be written as
N(t)=No (1/2)^(t/t 1/2)
where
No= The amount of the radioactive substance at time=0=milligrams
t 1/2= the half-life= 6 hours
t=24 hours
N(t) = the amount at time t
Step 2--- Solving
N(t)=No (1/2)^(t/t 1/2)
=N(t)=12 x ( 1/2) ^ (24/6)
= 12 x (1/2) ^4
= 12 x 0.0625
= 0.75 milligrams

What is Triangle?A triangle is a three-sided polygon that consists of three edges and three vertices.
Two triangles are said to be congruent if all three corresponding sides are equal and all the three corresponding angles are equal in measure.
1.The triangle is congruent by ASA postulate
If two angles and the included side of one triangle are congruent to two angles and the included side of a second triangle, then the triangles are congruent.
2. The triangle is congruent by SSS postulate
If all three sides of a triangle are congruent to corresponding three sides of other triangle then the two triangles are congruent.
3. The triangle is congruent by SAS postulate
if two sides of one triangle and the angle included between them are congruent to two sides and the included angle of a second triangle, then the triangles are congruent.
4. The triangle is congruent by SSS postulate

c) 8t+3r-7t-9r
=>8t-7t-9+3
=> t-6r
Hope it helps!
Answer:
3p , 5s , t - 6r
Step-by-step explanation:
(a)
4p + 2p - 3p ← add the first 2 terms
= 6p - 3p
= 3p
(b)
9s - 5s + 2s - s
= 4s + 2s - s
= 6s - s
= 5s
(c)
8t + 3r - 7t - 9r ← collect like terms
= (8t - 7t) + (3r - 9r)
= t - 6r
Which can be used to describe the expression? Check all that apply.
Answer:
B and D
Step-by-step explanation:
One thing is for certain. The final answer will be 1/r^12 or r^(-12)
When written as the given of (r^-4)^3, the powers are multiplied.
The first one is false. There are 4 factors of r^-4 If you get an answer that says it is true, then the question means that r^-4 is 3 equal factors of r^-12
B is true
C: not true. The exponents are multiplied, not added.
D is true
E: not true. This is the same thing as C.
What are the next three terms in the sequence? 2, -3, -6, 18, … -108, -1,944, -209,952 -108, 1,944, -209,952 -108, -1,944, 209,952 108, 1,944, 209,952
Answer: -108, -1,944, 209,952
Step-by-step explanation:
The the next term in this sequence is being determined by multiplying the last two numbers of the sequence.
Next three terms are;
= -6 * 18
= -108
= 18 * -108
= -1,944
= -108 * -1,944
= 209,952
What is the value of arccos(sine (StartFraction pi Over 2 EndFraction))?
Answer:
0 radians or 2π radians
Step-by-step explanation:
arccos(sine (StartFraction pi Over 2 EndFraction)) is expressed as;
cos^(-1) (sin π/2)
Now, (sin π/2) in radians is same as (sin 180/2) = sin 90 in degrees.
Thus;
(sin π/2) = 1
Thus;
cos^(-1) 1 = 0
It could also be 360° in the fourth quadrant since cosine is positive there too.
Thus,
cos^(-1) (sin π/2) = 0° or 360°
In radians, this gives; 0 radians or 2π radians
0 radians or 2π radians is the value of arccos(sine (StartFraction pi Over 2 EndFraction)).
Here, we have,
given that,
The term is: arccos (sine (StartFraction pi Over 2 EndFraction)
so, we get,
arccos(sine (StartFraction pi Over 2 EndFraction)) is expressed as;
cos^(-1) (sin π/2)
Now, (sin π/2) in radians is same as (sin 180/2) = sin 90 in degrees.
Thus;
(sin π/2) = 1
Thus;
cos^(-1) 1 = 0
It could also be 360° in the fourth quadrant since cosine is positive there too.
Thus,
cos^(-1) (sin π/2) = 0° or 360°
In radians, this gives; 0 radians or 2π radians.
