Answer:
1. b⁵
2. +16m⁹
Step-by-step explanation:
1. Add exponents: b³⁺² = b⁵
2. Negative and Negative = positive
2*8 = 16
m⁴⁺⁵ = m⁹
Hence: + 16m⁹
Answer:
[tex]1) \: {b}^{5} [/tex]
[tex]2) \: \: + 16 {m}^{9} [/tex]
Step-by-step explanation:
[tex] {b}^{3} \times {b}^{2} = {b}^{3 + 2} = {b}^{5} [/tex]
we know that
[tex]( - ) \times( - ) = ( + )[/tex]
So
[tex] - 2 {m}^{4} \times - 8 {m}^{5} \\ = + 16 {m}^{9} [/tex]

The difference in cost per mile is $0.94.
Step-by-step explanation:
Uber
7x = 20.37
x = $2.91 per mile
Lyft
4y = 15.4
y = $3.85 per mile
3.85 - 2.91 = 0.94
Hello.
To find the difference in cost per mile, divide the cost by the amount of miles, then subtract the two answers.
20.37 / 7 = 2.91 (cost per mile {cpm} for Uber)
15.40 / 4 = 3.85 (cost per mile {cpm} for Lyft)
3.85 - 2.91 = 0.94
The difference in cost per mile is $0.94

A school nurse can give 25 eyes test in a two-hour period. How long will it atke the nurse to give eye test to all 600 student sin her school?
Answers
Answer:
96 hours
Step-by-step explanation:
25 eyes - 2 hours
1200 eyes* - x hours
[tex]x = \frac{2 \times 1200}{25} [/tex]
[tex]x = 96[/tex]
*each student has 2 eyes. So 600 students have 600×2=1200 eyes.
It will take the nurse 48 hours to give eye tests to all 600 students in her school.
What is Expression?An expression is combination of variables, numbers and operators.
If the nurse can give 25 eye tests in two hours, then she can give 12.5 tests in one hour (since 25 divided by 2 equals 12.5).
To give eye tests to all 600 students, the nurse will need to give 600 tests in total.
Using the rate of 12.5 tests per hour, we can set up a proportion:
12.5 tests / 1 hour = 600 tests / x hours
Apply Cross-multiplication
12.5 tests × x hours = 600 tests
Divide both sides by 12.5 tests
we get, x hours = 600 tests / 12.5 tests per hour
x hours = 48 hours
Therefore, it will take the nurse 48 hours to give eye tests to all 600 students in her school.

Find missing angle !.
Answers
Answer:
[tex]\huge\boxed{130 \textdegree}[/tex]
Step-by-step explanation:
We can use a couple of angle relationships to find the missing angle.
1. All angles in a triangle add up to 180°
We know that all angle in a triangle will add up to 180°. Since we know the measure of 2, we can find the other angle easily.
[tex]180-35-95\\\\180-130\\\\50[/tex]
So the other angle in the triangle is 50°.
2. The 50° angle and the missing angle are supplementary.
We know that the missing angle and the third triangle angle are supplementary. This means that their angle measures will add up to 180°.
Since we know one, we can find the measure of the other.
[tex]180-50\\\\130[/tex]
So the missing angle is 130°.

Complete question :
Tabby is building two models of the Eiffel Tower. The scale factor of Model 2 to Model 1 is 1/4
____________Eiffel Tower(ft) _ M 1 (in) _M2 (in)
Height _______ 984 ______11.808 ____?
W of base ____ 328 _______? _______?
Answer:
Model 1 :
Width of Base = 328 * 0.012 = 3.936 inch
Model 2 :
Height = 11.808 * 4 = 47.232 inches
Width of base = 4 * 3.936 = 15.744 inches
Step-by-step explanation:
____________Eiffel Tower(ft) _ M 1 (in) _M2 (in)
Height _______ 984 ______11.808 ____?
W of base ____ 328 _______? _______?
Scale factor of Model 2 to Model 1 is 1/4
Model 1 : Model 2
1 : 4
The scale factor of actual tower to model 1
984ft = 11.808 inches
Hence,
1 ft = 11.808 / 984
1 ft = 0.012 inch
Model 1 :
Width of Base = 328 * 0.012 = 3.936 inch
Since ;
Model 1 : Model 2 ; 1 / 4
1 : 4
Model 2 :
Height = 11.808 * 4 = 47.232 inches
Width of base = 4 * 3.936 = 15.744 inches
At Petey's Pizza, two large one-topping pizzas and three dozen wings cost $54. Four large one-topping pizzas and one dozen wings cost $48. Let (L) represent the number of large one-topping pizzas, and let (W) represent the number of dozens of wings. Write a system of equations you could use to find the cost of a single one-topping pizza and a dozen wings.
Answers
Answer:
2L + 3W =54
4L + W = 48.
Step-by-step explanation:
Given
L = Large one-topping Pizzas
W = Dozen Wings
From the first statement; we have that:
2L and 3W cost $54.
The expression for this is:
2L + 3W =54
From the second statement; we have that:
4L and 1W cost $48.
The expression for this is:
4L + W = 48.
Hence; The system of equations is
2L + 3W =54
4L + W = 48.

To be the same they must equal each other.
4.50 + 0.65x = 0.40x + 5
isolate the variable
subtract 4.50 from both sides
0.65x = 0.40x + 0.50
subtract 0.40x from both sides
0.25x = 0.50
divide both sides by 0.25
x = 0.50 ÷ 0.25
x = 2

Step-by-step explanation:
There are 5 numbers greater then 3, and of those 5, five and seven are the only odd numbers. So that is 2/8
If you are only talking about the numbers that are actually greater then 3 as your population, it is 2/5 :)
(I would appreciate Brainliest, please and thanks)
If a number randomly chosen is greater than 3, the probability that the number is odd is 2/5
How to determine the probability?The set of numbers is given as:
Set = {1, 2, 3, 4, 5, 6, 7, 8}.
The numbers greater than 3 are:
G3 = {4, 5, 6, 7, 8}
The odd numbers greater than 3 are
OG3 = {5, 7}
The required probability is then calculated using:
P = n(OG3)/n(G3)
This gives
P = 2/5
Hence, the probability is 2/5
