Answer:
144 minutes or 2 hours and 24 minutes
Step-by-step explanation:
12 miles divided by 2 miles = 6
24 * 6 - 144
So the final answer is 144.
Answer: 144 minutes
Step-by-step explanation:
If she can run 2 miles in 24 minutes and she needs to run 12 miles you need to multiple 24 and 6 ( You get a six because 24 minutes is for TWO miles. So you need to split the 12 in half.)
One number is 1 more than 7 times the other number. If their sum is 73 more than
twice the smaller number. Find the numbers.
[tex]\boxed{\boxed{\pink{\bf The \ two \ numbers \ are \ 12 \& \ 85 . }}}[/tex]
Step-by-step explanation:Given that , One number is 1 more than 7 times the other number. If their sum is 73 more than
twice the smaller number. And we need to find the numbers. So let us take the
First Number be x .Second number be 7x+1 .[tex]\underline{\red{\boldsymbol{ According \ to \ the \ Question :- }}}[/tex]
[tex]\bf\implies 2( Small \ no.) + 73 = Bigger \ no. + Smaller \ no.\\\\\bf\implies 2x + 73 = x + 7x + 1\\\\\bf\implies 2x + 73 = 8x + 1 \\\\\bf\implies 8x - 2x = 73-1 \\\\\bf\implies 6x = 72 \\\\\bf\implies x =\dfrac{72}{6} \\\\\bf\implies \boxed{\red{\bf x = 12 }}[/tex]
Hence the smaller number is 12 and the bigger number will be :-
[tex]\bf \implies Number_{bigger} = 7x + 1 \\\\\bf\implies Number_{bigger} =7(12)+1\\\\\bf\implies Number_{bigger} = 84 + 1 \\\\\bf\implies \boxed{\red{\bf Number_{bigger}=85 }}[/tex]
Hence the bigger number is 85 and the smaller number is 12.Step-by-step explanation:
let us say the number: x
7x+1=y
x+y=73+2x
y-73=2x-x
y-73=x or
x=y-73
then, 7x+1=y
x=y-73
then after,we'll substitute
7x+1=y
7(y-73)+1=y
7y-511+1=y
7y-510=y
7y-y=510
6y=510
y=510/6
y=85
x=y-73
x=85-73
x=12
Therefore y=85 & x=12

The local newspaper has letters to the editor from 10 people. If this number represents 5% of all the newspaper's readers, how many readers does the newspaper have?
The newspaper has ___ readers.
Answer:
200 readers
Step-by-step explanation:
question is: 5% of what number is 10
is = percent
of 100
is = 10
of = unknown (call is 'n')
5% = 5/100
10 = 5
x 100
now, cross-multiply: 5x = 1000
divide each side by 5
x = 200

Answer:
1. (2x^2+x-1)
Step-by-step explanation:
expanding (2x^2-1)^2. multiplying (x-2) (1-2x)
= 4x^2-4x+1. = x-2x^2-2+4x
= -2x^2+5x-2
(4x^2-4x+1-2x^2+5x-2)
=2x^2+x-1
Answer:
1.) (2x - 1)(x + 1)
2.) a = 6 ; b = -1
4.a.) x = all rational numbers excluding (-2÷3)
4.b.) x = -1
4.c.) Yes. x = 1÷2
Step-by-step explanation:
E(x) = (2x - 1)² + (x - 2)(1 - 2x) F(x) = ax²-bx-2
F(1) = 5 ; F(-2) = 20
a-b=7 ; 4a+2b=22
3.Answer) Q(x) = 6x² + x - 2
= 6x² + 4x - 3x - 2
= (3x + 2)×(2x - 1)
Hence verified!
P(x) = E(x) ÷ Q(x)
= (x + 1)÷(3x + 2)
Here, x belongs to,
[tex]( - \infty \: to \: - 2 \div 3) union( - 2 \div 3 \: to \: \infty )[/tex]
Means, except x = -2÷3 , all real numbers are valid excluding complex numbers.
P(x) = (x + 1)÷(3x +2) = 0
= > x = -1
The increase in pressure (P) is a linear function of the depth (d) to which a scuba diver descends. This is the function: P(d)=0.445d + 14.7.
1.) What does the initial value represent?
2.) What does the rate of change represent?
Answer:
Initial value = 14.7
Rate of change = 0.445
Step-by-step explanation:
Given the linear function :
P(d) = 0.445d + 14.7
The linear equation above takes the general. Form of a slope - intercept equation :
y = mx + c
Where ; m = slope or gradient = rate of change in y per unit change in x
c = intercept , which is the intial value of y when x = 0
Thus using the above information ;
Initial value = intercept value = 14.7
The rate of change is the slope value = 0.445
how do you find the value in a ratio?
Answer:
In mathematics, a ratio indicates how many times one number contains another. For example, if there are eight oranges and six lemons in a bowl of fruit, then the ratio of oranges to lemons is eight to six. Similarly, the ratio of lemons to oranges is 6∶8 and the ratio of oranges to the total amount of fruit is 8∶14.

A dump truck bar 1/3 of a ton of rocks on the 1st beat trip when half of a ton on the 2nd trip and forfeits of a tone on the 3rd trip what was the total way of the rock.
Answer: 1/30
Step-by-step explanation:
Here's the correct question:
A dump truck brought 1⁄3 of a ton of rock on the first trip, 1⁄2 of a ton on the second trip, but on the third trip, had to take back 4⁄5 of a ton. What was the total weight of the rock left at the construction site?
To calculate the the total weight of the rock left at the construction site goes thus:
= 1/3 + 1/2 - 4/5
The lowest common multiple of 3,2 and 5 is 30. Therefore, we'll make the fractions have a common denominator.
= 1/3 + 1/2 - 4/5
= 10/30 + 15/30 - 24/30.
= 1/30
Carla is going on a boat tour. The boat will travel a total distance of 40 kilometers during the 10 hour tour. If the boat travels at a constant speed during the tour, what distance in kilometers should the boat travel in 7 hours? Choose the correct answer below.
Answer:
Distance cover in 7 hour = 28 kilometer
Step-by-step explanation:
Given:
Distance = 40 kilometers
Time taken = 10 hour
Find:
Distance cover in 7 hour
Computation:
Distance cover in 7 hour = (40/10)7
Distance cover in 7 hour = (4)7
Distance cover in 7 hour = 28 kilometer

Prove that:
1+cot²a / 1 + cosec a = cosec a
Step-by-step explanation:
LHS= 1 + cot^2A/1+cosecA
=(1+cosecA + cot^2A)/1+cosecA
{By using basic trigonometric theorem cot^2A = cosec^2A - 1}
=(1+cosecA + cosec^2A - 1)/(1+cosecA)
=(cosecA + cosec^2A)/(1+cosecA)
=[cosecA (1+cosecA)]/(1+cosecA)
{Cancelling 1+cosecA}
=cosecA

The terminal side of ø quadrant IV and sin ø = -12/13. What is the cos ø?
A. 5/13
B. 5/12
C. -5/12
D. -5/13
Answer:
Step-by-step explanation:
cos^2θ = 1 - sin^2θ = 1 - 144/169 = 25/169
cos θ is positive in Quadrant IV
cos θ = √(25/169) = 5/13
The value of the cos θ is 5/13 because cos is positive in IV option (A) is correct.
What is Trigonometric functions?Trigonometric functions defined as the functions which show the relationship between angle and sides of a right-angled triangle.
We have: The terminal side of θ is in quadrant IV quadrant
sinθ = -12/13
cos²θ = 1 - sin²θ
cos²θ = 1 - (-12/13)²
cos²θ = 1 - 144/169
cos²θ = 25/169
cos θ = √(25/169)
cos θ = 5/13
cos θ is positive in Quadrant IV
Thus, the value of the cos θ is 5/13 because cos is positive in IV option (A) is correct.

Graph g is a translation of the graph of y= sin x (dashed line).a) write down the equation of g b) write down the coordinates of the point p
Answer:
a) [tex]G(x)= \sin x + 2[/tex]
b) The coordinates of P are

Step-by-step explanation:
Translation
The dashed line shows the graph of the function
[tex]y = \sin x[/tex]
This function has a maximum value of 1, a minimum value of -1, and a center value of 0.
a)
Graph G shows the same function but translated by 2 units up, thus the equation of G is:
[tex]\boxed{G(x)= \sin x + 2}[/tex]
b) The coordinates of P correspond to the value of
[tex]x = \frac{3\pi}{2}[/tex]
The value of G is
[tex]\displaystyle G(\frac{3\pi}{2})= \sin \frac{3\pi}{2} + 2[/tex]
Since
[tex]\sin \frac{3\pi}{2}=-1[/tex]
[tex]\displaystyle G(\frac{3\pi}{2})= -1+ 2=1[/tex]
The coordinates of P are
