Answer:
-18°F
Step-by-step explanation:
Starting temp = -12
Every hour temp drops by 3
Total elapsed hours = 2
3(2) = 6 total degrees dropped
-12 - 6 = -18 degrees F
Answer:
it will be -6f at 6:00am

Answer:
( 2 , 1 )Step-by-step explanation:
2x - 2y = 2
5x + 2y = 12
7x = 14
x = 2(2x - 2y = 2)-5
(5x + 2y = 12)2
-10x + 10y = -10
10x + 4y = 24
14y = 14
y = 1x = 2
y = 1
(2,1)
2(2x + 3)^2– 7(2x + 3) - 4

The equation d=3t represents the relationship between the distance (d) in inches that a snail is from a certain rock and the time (t) in minutes. What does the number 3 represent?
Answer:
Speed
Step-by-step explanation:
To find the distance the formula is d=st. Where d is the distance, s is speed, and t is time. So in the equation, 3 must be the speed of the snail.

The half-life of the element radon (Rn86) is 3.8 days. In a sample originally containing 1 gram of radon, the amount of left over days is given by the model () = (0.5)t/3.8 a) How much radon will be present after 7.6 days? b) How much radon will be present after 10 days?
Answer:
a.0.25 g
b.0.16 g
Step-by-step explanation:
We are given that
Half-life of the element radon=3.8 days
Mass of sample of radon=1 g
The amount of radon left after t days is given by
[tex]A(t)=(0.5)^{\frac{t}{3.8}}[/tex]
a.
We have to find the amount of radon left after 7.6 days.
Substitute t=7.6 in the equation
Then, we get
[tex]A(7.6)=(0.5)^{\frac{7.6}{3.8}}[/tex]
[tex]A(7.6)=0.25 g[/tex]
Hence, the amount of radon will be present after 7.6 days=0.25 g
b. We have to find the amount of radon left after 10 days.
Substitute t=10 in the equation
Then, we get
[tex]A(10)=(0.5)^{\frac{10}{3.8}}[/tex]
[tex]A(10)=0.16g[/tex]
Hence, the amount of radon will be present after 10 days=0.16 g

Use the Pythagorean Theorem to solve for the missing side length. Round to the nearest tenth if necessary.
a = 8 b = c = 10
Answer:
B= 6
Step-by-step explanation:
pythagorean theorem formula is a² + b² = c²
so: 8² + b² = 10²
then: 64 + b² = 100
subtract 64 from both sides to get b²= 36
square root 36 and you get 6 for b
answer: B= 6
Determine whether the triangles are similar. or not.
If similar, state how.
A. similar, AA
B. similar, sss
C. Similar, SAS
D. Not similar
Answer:
B.Similar,sss
Step-by-step explanation:
Since no angles measures are provided in these triangles, we can determine if these triangles are similar by using the SSS Similarity Theorem. This requires that we determine if each pair of corresponding sides have an equal ratio.

Simplify the expression:
–3(–2h + 3) =
Answer: 6h - 9
=================================================
Explanation:
The outer term -3 is multiplied by every term inside
We get the following
-3 times -2h = 6h-3 times 3 = -9This means the original expression becomes 6h-9. I applied the distributive property.
The graphs of rational functions m and n have the same vertical asymptotes, and both have a single x-intercept at x = 5.
Which equation could represent function n?
A.
n(x) = 5m(x)
B.
n(x) = m(x) + 5
C.
n(x) = m(x − 5)
D.
n(x) = m(x + 5)
Answer:
A
Step-by-step explanation:
We are given two rational functions m(x) and n(x) that have the same vertical asymptotes both with a single x-intercept at x = 5.
The correct choice will be A.
Recall the transformations of functions.
B represents m(x) being shifted up 5 units. If the function is shifted up, the vertical asymptotes will be the same, but the x-intercept will change.
C represents m(x) being shifted 5 units to the right. This changes both the x-intercept and the vertical asymptotes.
Likewise, D represents m(x)being shifted 5 units to the left. Again, this will change both the x-intercept and the vertical asymptotes.
Therefore, the only choice left is A. It represents a vertical stretch by a factor of 5. This preserves the x-intercepts and the vertical asymptotes. Consider, as an example, the function:
[tex]\displaystyle m(x)=\frac{x-5}{(x-3)(x-7)}[/tex]
If n(x)=5m(x), we can see that:
[tex]\displaystyle n(x)=\frac{5(x-5)}{(x-3)(x-7)}[/tex]
So, the x-intercepts and vertical asymptotes are preserved.

b = 9
C = 21
Answer:
1. b=39.497
2. c=3.606
3. a=18.974
Step-by-step explanation:
1.
41^2-11^2=b^2
1681-121=b^2
b^=1560
b=39.497
2.
2^2+3^2=c^2
4+9=c^2
c^2=13
c=3.606
3.
21^2-9^9=a^2
441-81=a^2
a^2=360
a=18.974
Leo reads 14 pages in 1/2 hour. What is the unit rate for pages per hour? For hours per page?
Answer:
1:28 | 1:1/28
Step-by-step explanation:
We can show the first two numbers as a ratio:
14:1/2
But we want that second number to be 1 so we can multiply by 1:
28:1 <------ Pages per hour
But now we need the left to be 1, so we divide by 28:
1/28:1
Then flip:
1:1/28

Step-by-step explanation:
The circle is filled in and the numbers are going lower so x is less than or equal to 7. I hope this helps and have a great day!
Answer: D
Closed circle mean it would be an “equal to.” Since the line is going to the left of 7 it means x is less than 7.
Given that the area of a triangle is given by the formula A =
- 2oh, what is the value of A if b = 4 cm and h = 6
cm?
Answer:
12 square centimeters
Step-by-step explanation:
Not sure what formula you are using here. The standard one is A=1/2 b h, where b is the base and h is the height.
base=4
height=6
A= 1/2 x 4 x 6
A=1/2 x 24
A=12 cm^2
