Answer:
11 hours
Step-by-step explanation:
To find how many hours it took, divide -33 by -3
-33/-3
= 11
So, it took 11 hours for the change to be -33°F
A marathon race is 26.2 miles. While running the marathon, Maxwell stops every 3.25 miles for water. If he has already stopped for water 5 times, how many more miles does Maxwell have to run? PLEASE HELP I WILL MARK YOU BRAINLIEST AND PLEASE EXPLAIN
Answer:
Hey there!
If he has already stopped five times for water, he has run 5(3.25), or 16.25 miles.
He has 26.2-16.25, or 9.95 more miles to run.
Let me know if this helps :)
Answer:
9.95 miles
Step-by-step explanation:
How many times he stopped × number of miles before break = total miles that has been run.
3.25 × 5 = 16.25
26.2 - 16.25 = 9.95 miles.
Solve the following equations below by showing all the steps.
- 1. 9(4 - 2x) – 3 = 4 - 6(3x – 5)
Answer:
No real solution
Step-by-step explanation:
First off I'm assuming that the 1 or -1 at the begging is just the problem number:
First you distribute on both sides
36 - 18x - 3 = 4 - 18x + 30
Then combine like terms
33 - 18x = 34 - 18x
Then rearrange the terms by adding 18x to both sides and subtracting both sides by 33. You should get:
0 = 1
When you add positive 18x it cancels the -18x out. And 34 - 33 is 1. Obviously, zero cannot equal 1 so there is no real solution
Least to greatest 2.71,2 3/4,5,5/2
Answer:
3/4<5/2<2.71
Step-by-step explanation:
3/4<5/2<2.71
Answer:
5/2, 2.71, 2 3/4, 5/2
Step-by-step explanation:
This is because (5/2) is equal to 2.5
and 2.71 is equal to 2.71
then (2 3/4) is equal to 3.75
and finally 5 is just 5, so then you put them in order (Least to Greatest) and then you revert them back to their original form.
hope this helps.

f 72°
g 108°
h 72°
i 108°
j 108°
k 108°
m 105°
n 79° = opposite angle
p 90° = 180-90=90
q 116° = since m is 105, and the third angle is 180-169=11, the angle next to q is 64. 180-64=116
s 72°
t 119°
Step-by-step explanation:
a 64°
b 116°
c 116°
d 64°
e 108°
f 72°
g 108°
h 72°
i 108°
j 108°
k 108°
m 105°
n 79° = opposite angle
p 90° = 180-90=90
q 116° = since m is 105, and the third angle is 180-169=11, the angle next to q is 64. 180-64=116
s 72°
t 119°
Answer:
d = 64°
c = 180° - 64° = 116°
a = 64°
b = 180° - 64° = 116°
m = 180° - 75° = 105°
t = 180° - 61° = 119°
f = 180° - 108° = 72°
g = 108° = e
h = 180° - 108° = 72°
i = j = g = 108°
k = i = 108°
s = 180° - 108° = 72°
n = 79°
p + n + 75° + q = 360° (their vertices form a quadrilateral)
--> q = 360° - 90° - 79° - 75° = 116°
(i see that n,p,q don't have any special relationships at all but i'm not sure about that, sorry)

Answer:
a^ (5/2)
Step-by-step explanation:
a^5 ÷ a ^ (5/2)
We know that x^b ÷ x^c = x^ ( b-c)
a^ ( 5 - 5/2)
a^ ( 10/2 - 5/2)
a^ (5/2)
Answer:
[tex]a^{\frac{5}{2} }[/tex]
Step-by-step explanation:
Using exponent rules, if we have [tex]a^x \div a^y[/tex] then the result can simplify to [tex]a^{x-y}[/tex]
So [tex]a^5 \div a^{\frac{5}{2}}[/tex] is the same as [tex]a^{5 - \frac{5}{2}}[/tex].
[tex]\frac{5}{1} - \frac{5}{2} = \frac{10}{2} - \frac {5}{2} = \frac {5}{2}[/tex]
So [tex]a^{\frac{5}{2}}[/tex].

The local humane society is restocking on cat food to prepare for kitten season. Very young kittens need kitten formula which costs 3.99 per bottle. Older kittens need wet cat food which costs 1.5 per can.
Answer:
Step-by-step explanation:
A.) Let z be the variable denoted for the total cost of all kitten supplies. Then, let x be the number of bottles and let y be the number of cans. The equation would be:
z = 3.99x + 1.50y
The coefficients are 1 for z, 3.99 for x and 1.50 for y.
There are no constants.
The variables are z, x and y.
Part B.) Substitute x=30 and y=120 to the equation in part A to determine z.
z = 3.99(30) + 1.50(120)
z = $299.7
Part C.
Sales tax would be 7% of the total cost. This would be added as a constant. The expression would be:
z = (3.99x + 1.50y)(1+0.07)
Substituting x=30 and y=120,
z = (3.99*30 + 1.50*120)(1+0.07)
z = $320.679
The parallelogram shown below has an area of 15 squared. Find the missing height. h=? units
Answer:
5 units
Step-by-step explanation:
The area of a parallelogram is given by the formula:
[tex]A=bh[/tex]
Where b is the base and h is the height.
So we know that the area is 15. We can also see that the base is 3. Thus:
[tex]15=3h[/tex]
Divide both sides by 3:
[tex]h=5[/tex]
So, the height is 5 units.
Answer:
h=3 units
Step-by-step explanation:
Equation for finding the area of a parallelogram:
b·h=area
Equation for this answer:
3·h=15
So divide 15 by 3 and you will get your answer.
15÷3=5
So the answer is:
3·5=15

Consider the equation 3p – 7 + p = 13. What is the resulting equation after the first step in the solution?
p – 7 = 13 – 3p
2p – 7 = 13
3p – 7 = 13 – p
4p – 7 = 13
Answer:
4p - 7 = 13
Step-by-step explanation:
The first step of the solution should be to simplify the left side by combining like terms. In this case, 3p and p are the like terms and 3p + p = 4p so the answer is 4p - 7 = 13.
Answer:
4p - 7 = 13

Plot the approximate location of √6 on the number line JUST ANSWER IT
Answer:
Step-by-step explanation
That's the answer
The position of the √6 on the number line is slightly right of the 2.4.
We need to determine the approximate location of √6 on the number line.
What is a number line?A number line is defined as the number marked on the line calibrated into an equal number of units. For example -1, 0, 1, and so on.
Here,
In the general conclusion,
√4< √6 < √9
2 < √6 < 3
So, the value of the √6 lies between 2 and 3.
√6 = 2.445
So the position of the √6 on the number line is slightly right of the 2.4.
Thus, the position of the √6 on the number line is slightly right of the 2.4.

There are bacteria in a petri dish. After 20 minutes, every bacterium splits into two. Explain how you can use the properties of exponents to write an expression for the resulting number of bacteria.
Answer:
[tex]T_n = \frac{2^na}{2}[/tex]
Step-by-step explanation:
Given
Bacteria splits to 2 at every 20 minutes
Required
Explain how to get the resulting number of bacteria
To do this we simply make use of geometric progression formula;
[tex]T_n = ar^{n-1}[/tex]
In this case; r = 2 (rate at which they split);
[tex]T_n = a * 2^{n-1}[/tex]
a represents the initial number of bacteria in the dish
Apply law of indices
[tex]T_n = a * \frac{2^n}{2^1}[/tex]
[tex]T_n = a * \frac{2^n}{2}[/tex]
[tex]T_n = \frac{2^na}{2}[/tex]
Assume, we want to determine the number of bacteria at the 10th 20 minutes (in other words, 200 minutes), the value of n will be 10

find mn if mn = x+1, nr=3x and mr =11
Answer:
mn = 3.5 unit
Step-by-step explanation:
Given:
mn = x+1 unit
nr = 3x unit
mr = 11 unit
Find:
mn
Computation:
mr = mn + nr
11 = x+1 + 3x
11-1 = x + 3x
10 = 4x
x = 10/4
x = 2.5 unit
So,
mn = x+1 unit
mn = 2.5+1 unit
mn = 3.5 unit
