Answer:
0.0390cm/minStep-by-step explanation:
We are expected to do a unit conversion here.
let us convert days to minutes first
6.5days to minutes
1 day has 1440miuntes
6.5 days has x minute
cross multiply we have
x=6.5x1440
x=9360minute
let us convert yards to cm
1 yard to 91.44 cm
4 yards has xcm
cross multiply we have
x=4x91.44
x=365.76cm
the speed in cm per mins is
speed=365.76/9360m
speed=0.0390cm/min

solve -8(n+5)=-44-8n
Answer:
there are no solutions
Step-by-step explanation:
HERE ARE THE STEPS IN CASE U NEED EM :)
Step 1: Simplify both sides of the equation.
−8(n+5)=−44−8n
(−8)(n)+(−8)(5)=−44+−8n(Distribute)
−8n+−40=−44+−8n
−8n−40=−8n−44
Step 2: Add 8n to both sides.
−8n−40+8n=−8n−44+8n
−40=−44
Step 3: Add 40 to both sides.
−40+40=−44+40

Step-by-step explanation:
Suppose a basketball player has made 291 out of 389 free throws. If the player makes the next 2 free throws, I will pay you $38. Otherwise you pay me $50. Step 1 of 2 : Find the expected value of the proposition. Round your answer to two decimal places. Losses must be expressed as negative values.
Answer:
The expected value of the proposition is -$0.76.
Step-by-step explanation:
It is provided that a basketball player has made 291 out of 389 free throws.
Then rate of him making a free throw is,
[tex]P(\text{free throw})=\frac{291}{389}=0.7481[/tex]
The probability that he makes the next 2 free throws is:
[tex]P(\text{Next 2 free throws})=(0.7481)^{2}=0.5596[/tex]
The payout rules are:
If the player makes the next 2 free throws, I will pay you $38. Otherwise you pay me $50.Compute the expected value of the proposition as follows:
Expected value = $38 × P (Makes both) + (-$50) × P (Misses both)
[tex]=($38\times 0.5596)+(-$50\times (1-0.5596))\\=21.2648-22.02\\=-0.7552\\\approx -$0.76[/tex]
Thus, the expected value of the proposition is -$0.76.
Write the equation in standard form. x + y = 6y
[tex]x + y = 6y[/tex]
Subtract the sides of the equation minus 6y
[tex]x + y - 6y = 0[/tex]
[tex]x - 5y = 0[/tex]
[tex] - 5y + x = 0[/tex]
[tex]a = - 5[/tex]
[tex]b = 1[/tex]
[tex]c = 0[/tex]

which graph displays a rate of change of 2.5?
Answer:
The second graph.
Step-by-step explanation:
The first graph has a negative slope, so that can't be the right answer.
The last graph isn't steep enough to show a rate of 2.5.
This leaves us with the middle graph which is correct.
Determine if the two fraction are equivalent, 65/4, 13/2
Answer:
The fractions are not equivalent. If you cross multiply 65 x 2 = 130 and 4 x 13 = 52. 130 > 52. Set them as a proportion. [tex]\frac{65}{4} = \frac{13}{2}[/tex]
They are not equal.
For 65/4 you cannot divide it by 2 and then get 13/2. You would get 32.5/2.
32.5/2 is not equal to 13/2
hope this helps :)
What products are defined for these matrices?
Drag the operation to the boxes to correctly complete the table.
Answer:
Product is defined [tex]{}[/tex]
(ML, MP, NM, PQ, PL, LP, MQ, LQ)
Product is not defined
(LM, PM, MN, QP, QM, NQ, QN, NL, LN, NP, PN, QL)
Step-by-step explanation:
During multiplication of matrices, the number of columns of the first matrix must be equal to the number of rows of the second matrix it is multiplying.
Therefore, we can only multiply a m×n matrix to a n×c matrix as follows;
We can only multiply (m×n)·(n×c) → Product is defined
We can not multiply (n×c)·(m×n) →∞ Product is not defined.
Gregoria borrowed $2,450, to be paid back at 3.5% simple interest. She spent $3221.75 in all to repay the loan. How many years did Georgia take to repay the loan?
Answer: 9 years
Step-by-step explanation:
Simple interest = PRT/100
where
P = principal = $2450
R = rate = 3.5%
T = time = unknown
Interest = $3221.75 - $2450 = $771.75
Simple interest = PRT/100
$771.5 = ($2450 × 3.5 × T)/100
$771.5 = $8575T/100
8575T = 771.5 × 100
8575T = 77150
T = 77150/8575
Time = 8.99 years = 9 years

find the smallest number by which 339 must be multiplied so that the product is a perfect cube. also find the cube root of the perfect cube so obtained
Answer:
The smallest number is 114921 and the cube root of the result is 339
Step-by-step explanation:
The number 339 can be factored as:
339 = 3 * 113
Both factors are prime, thus to produce a perfect cube, we must multiply by each factor to the power of 2, that is:
3^2*113^2=114921
When we multiply 339 by 114921 we get 38958219, a perfect cube which cube root is 339.
Thus, the smallest number is 114921 and the cube root of the result is 339

David watches Maria and Alma race electric trains around a track. Maria's train goes around the track in 10 seconds. Alma's train goes around the track in 12 seconds.
How long will it take for both trains to cross the finish line together the first time?
A
30 seconds
B
60 seconds
C
72 seconds
D
120 seconds
Answer:
60 seconds.
Step-by-step explanation:
We have been given that Maria train can go around the track in 10 seconds. Alma train can go around the track in 12 seconds.
To find the number of seconds after which both trains will cross the finish line together the first time we will find LCM of 10 and 12. LCM will give us the smallest positive integer that is divisible by both 10 and 12.
Multiples of 10 are: 10, 20, 30, 40, 50, 60, 70,...
Multiples of 12 are: 12, 24, 36, 48, 60, 72, 84,..
We can see that least common multiple of 10 and 12 is 60, therefore, it will take 60 seconds for both trains to cross the finish line together the first time.

What integer represents the total charge of 7 electrons?
the integer that represents the total charge of 7 electrons is -1.The total charge of electrons is given by the formula:
total charge = number of electrons x charge of each electron
what are electrons ?
Electrons are subatomic particles that carry a negative electric charge. They are one of the fundamental particles that make up atoms, along with protons and neutrons. Electrons are found in shells or energy levels that surround the atomic nucleus
In the given question,
The total charge of electrons is given by the formula:
total charge = number of electrons x charge of each electron
The charge of an electron is a fundamental constant, which is equal to -1.602 x 10⁻¹⁹ Coulombs. Therefore, the total charge of 7 electrons can be calculated as:
total charge = 7 x (-1.602 x 10⁻¹⁹) C
total charge = -1.1214 x 10⁻¹⁸ C
Note that the charge of an electron is negative because it has an opposite charge to the positively charged protons in an atom. Therefore, the total charge of 7 electrons is also negative. To express this charge as an integer, we need to convert it to scientific notation and round to the nearest whole number. Rounding to the nearest whole number gives:
total charge = -1 x 10⁻¹⁸ C
Therefore, the integer that represents the total charge of 7 electrons is -1.

I'm confused on this problem 2/3x-1=5
Answer:
x=9
Step-by-step explanation:
2/3x-1=5
Add 1 to each side
2/3x-1+1= 5+1
2/3x = 6
Multiply each side by 3/2
2/3x*3/2 = 6*3/2
x = 9
Answer:
x=9
Step-by-step explanation:
You add one to both sides, multiply 3 to both sides (to further isolate x), and then divide by 2 on both sides. When you substitute back in, both sides of the equation are equal to each other.
Find the measure of this angle, and explain your answer.
Answer:
50
Step-by-step explanation:
180 - 90+40 = 50
Answer:
Answer: 50 degrees
Step-by-step explanation:
important things to know:the square in the bottom right means 90°all angles in a triangle add up to 180°using this knowledge, you can make the following equation:
90 + 40 + x = 180
130 + x = 180
now subtract 130 from both sides.
x = 180 - 130
x = 50°
