A train leaves Boston at 10:20 AM and arrives in Stamford at 1:00 PM. Find the distance between the stations if the average speed of the train is 60 mph
Answer: 160 miles
Step-by-step explanation: From 10:20 to 12:20 is 2 hours which is 120 minutes and it is 60mph so it is 1 mile per minute. 12:20 to 1:00 is 40 minutes so you add 40 to 120 which makes it 160. So the answer is 160 miles
Me podrian ayudar con ese ejercisio por favor?? Me salvarian 4. Dadas las sucesiones de término general an = n + 3 y bn = 5n − 1 , realiza las siguientes operaciones: a) an – bn b) an + 3bn 5. Escribe los ocho primeros términos de la sucesión ( an ) dada por: a1 = 1, a2 = 1, an = an−1 + an−2
Explicación paso a paso:
Dado
an = n + 3
bn = 5n-1
a) an-bn = n + 3- (5n-1)
= n + 3-5n + 1
= n-5n + 3 + 1
= -4n + 4
an-bn = 4-4n
b) an + 3bn = (n + 3) +3 (5n-1)
= n + 3 + 3 (5n) +3 (-1)
= n + 3 + 15n-3
= n + 15n + 3-3
= 16n + 0
= 16n
an + 3bn = 16n
3) Dado a1 = 1, a2 = 1
an = an-1 + an-2
Debemos escribir los primeros ocho términos de la secuencia.
a3 = a3-1 + a3-2
a3 = a2 + a1
a3 = 1 + 1
a3 = 2
a4 = a3 + a2
a4 = 2 + 1
a4 = 3
a5 = a4 + a3
a5 = 3 + 2
a5 = 5
a6 = a5 + a4
a6 = 5 + 3
a6 = 8
a7 = a6-a5
a7 = 8 + 5
a7 = 13
a8 = a7 + a6
a8 = 13 + 8
a8 = 21
Por tanto, los primeros ocho términos de la secuencia son 1, 1, 2, 3, 5, 8, 13 y 21

Which linear equation has no solution?
3/2 (9x +6) 3
5x + 12 = 5x -7
4x + 7 = 3x + 7
-3(2x - 5) = 15 - 6x
9514 1404 393
Answer:
5x + 12 = 5x - 7
Step-by-step explanation:
There will be no solution when the coefficients of x are the same on both sides of the equal sign and the constants are different. That is the case for ...
5x + 12 = 5x - 7
This reduces to ...
19 = 0 . . . . . no value of x will make this be true: NO SOLUTION

(-3/8) times 1 times (-9/10) times -8/3
Step-by-step explanation:
-3/8 × 1 × -9/10 × -8/3
we know
- × - = +
+ × - = -
therefore, since we have 3 negative factors we get a negative result.
we can ignore the completely neutral multiplication by 1.
-3/8 × -9/10 × -8/3 = -(3×9×8)/(8×10×3) = -9/10

If a basketball player made 72 out of 85 free throws attempts how many could she make in 200 attempts
Answer:
169
Step-by-step explanation:
Use a proportion:
72/85=x/200
Solve for x
(72)(200)=85x
x=(72)(200)/85
x=169.41≈ 169
She can make 169 of 200 free throws.

HEY CAN ANYONE PLS ANSWER MY MATH QUESTION!!!!1
Answer:
The blue and yellow macaw is 33 inches long.
Step-by-step explanation:
If the toucan is 22 inches long and it's two thirds the length of the macaw you can divide by two to find what one third is.
22 ÷ 2 = 11
So then you have to multiply by 3 to find what the full length is.
3 x 11 = 33 inches
Hope that helps and have a great day!
Answer:
33 inStep-by-step explanation:
Let the length of the macaw be xThe length of the toucan is 22 inThen we have equation
x*2/3 = 22x = 22 ÷ 2/3x = 22*3/2x = 33 inBlue-and-yellow macaw is 33 in long
There are 2,100 bacteria in a circular petri dish. The dish has a radius of 40 millimeters. What is the approximate population density? (Use 3. 14 for π) Area of a circle = πr2 0. 02 bacteria per square millimeter 0. 42 bacteria per square millimeter 2. 39 bacteria per square millimeter 52. 5 bacteria per square millimeter.
Answer:
B) 0.42
Step-by-step explanation:
population density=number of people/square units
we plug in 2,100 for the first one but we don't know the second one for that we need the area which is A=π[tex]r^{2}[/tex] so the radius is 40 millimeters so [tex]40^{2}[/tex] =1600 1600*π=5024
2,100/5024=0.417 round it up and it is 0.42
so B) 0.42 is the answer

Rewriting the whole as an Equivalent Fraction
4.1 Adding a whole to a fraction
Rewrite the whole as a fraction using (x-8) as the denominator :
-2 -2 • (x - 8)
-2 = —— = ————————————
1 (x - 8)
Equivalent fraction : The fraction thus generated looks different but has the same value as the whole
Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator
Adding fractions that have a common denominator :
4.2 Adding up the two equivalent fractions
Add the two equivalent fractions which now have a common denominator
Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:
3x2 + -2 • (x-8) 3x2 - 2x + 16
———————————————— = —————————————
1 • (x-8) 1 • (x - 8)
Trying to factor by splitting the middle term
4.3 Factoring 3x2 - 2x + 16
The first term is, 3x2 its coefficient is 3 .
The middle term is, -2x its coefficient is -2 .
The last term, "the constant", is +16
Step-1 : Multiply the coefficient of the first term by the constant 3 • 16 = 48
Step-2 : Find two factors of 48 whose sum equals the coefficient of the middle term, which is -2 .
-48 + -1 = -49
-24 + -2 = -26
-16 + -3 = -19
-12 + -4 = -16
-8 + -6 = -14
-6 + -8 = -14
20. The diagram shows a supplementary angle. Determine the value of x. *
Answer:
C
Step-by-step explanation:
supplementary angles sum to 180° , then
3x + 15 + 60 = 180 , that is
3x + 75 = 180 ( subtract 75 from both sides )
3x = 105 ( divide both sides by 3 )
x = 35
