As part of a training program for the Boston Marathon, a runner wants to build endurance by running at a rate of 12 mph for 15 min. How far will the runner travel in that time period? _ mi
The distance travelled by the runner running at a rate of 12 mph for 15 min is 3 miles.
Speed is the ratio of distance travelled to time taken. Speed is given by:
Speed = distance/time
Given that the runner is running at a rate of 12 mph for 15 min, hence:
speed = 12 mph, time = 15 min * 1/60 min per hour = 0.25 hours.
Hence:
Speed = distance/time
12 mph = distance/0.25 hours
distance = 3 miles
The distance travelled by the runner running at a rate of 12 mph for 15 min is 3 miles.

A type of fish for your aquarium costs $7 each. You can spend at most $56. How many of these fish can you buy? Write an inequality to model the problem. Then solve the inequality to find the number of fish.Over the next 13 months you have to read more than 65 books. You have to read x books per month. The inequality 13x>68represents this situation. Solve the inequality to find the number of books you have to read per month.
Answer:
x <= 8 ... you can buy a max of 8 fishes
6 books or more per month.
Step-by-step explanation:
Given the information provided, we can create the following inequality which multiplies the cost per fish ($7) by the number of fish we can buy (x) and it has to be less than or equal to $56
7x <= 56
We can now solve this inequality by isolating x
7x <= 56 ... divide 7 on both sides
x <= 8 ... you can buy a max of 8 fishes
-----------------------------------------------------------------------------------------------------------------
13x > 68 ... divide both sides by 13
x > 5.23
Since the number of books needs to be a whole number then we round this decimal up to 6. Meaning that you must read 6 books or more per month.

A triangle was translated 4 units down.
In the graph, which figure is the pre-image and which
figure is the image?
O AFGH is the image and A ABC is the pre-image
AFGH is the pre-image and AABC is the image.
Both triangles are images.
The image cannot be determined from the graph.
Given:
A graph that contains image and preimage.
To find:
Which figure is the preimage and which figure is the image.
Solution:
Initial figure is known as preimage and translated figure is known as image.
It is given that a triangle was translated 4 units down. It means, the upper triangle is preimage and the lower triangle is the image.
So, ΔFGH is the pre-image and ΔABC is the image.
Therefore, the correct option is B.
the answer is B :0

Find the value of y. Round your answers to the nearest tenth
Answer:
y ≈ 4.3
Step-by-step explanation:
Since the figures are similar then the ratios of corresponding sides are equal, that is
[tex]\frac{AB}{RS}[/tex] = [tex]\frac{ED}{VU}[/tex] , substitute values
[tex]\frac{6}{4}[/tex] = [tex]\frac{8}{y+1}[/tex] ( cross- multiply )
6(y + 1) = 32
6y + 6 = 32 ( subtract 6 from both sides )
6y = 26 ( divide both sides by 6 )
y ≈ 4.3 ( to the nearest tenth )
Answer:
4.3 Is the answer like the value of X in the nearest tenth.

8 + 25 x 2 to the power of 2
Answer:
3,364
Step-by-step explanation:
8 + 25 x 2
To solve this one, you multiply first according to PEMDAS. So,
25*2= 50
It is now 8+50 so you add that and you get 58
Now 58 with a power of 2 can als be written as 58^2
Basically you multiply 58 two times.
58*58=3,364
3,364

Answer:
One property of rectangles is that the diagonals of rectangles bisect each other, meaning 2 of JN is equal to JL.
We can form an equation off of this, 2(x+3) = 3x + 1 and then solve for x
2(x+3)= 3x + 1 First, distribute the 2 to each term in x+3,
the result should be:
2x + 6 = 3x+ 1 then subtract 2x from both sides
-2x -2x
the result should be :
6 = x + 1 subtract 1 from both sides
-1 -1
the result should be x=5
plug that into the equations and JN= 5+3, JL=15+1
The two correct options are
NM = 8 ( both of the diagonals are equal to eachother )
JL = 16

A certain man has a negative balance of P250 in his back account b) suppose he deposits P300 in his back account ,what is the current balance in his account?
Answer: $50
Step-by-step explanation:
From the question, we are informed that a certain man has a negative balance of P250 in his back account and that he then deposits P300 in his back account.
The current balance in his account? will then be gotten by adding the negative balance of $250 to the $300 deposited. This will be:
= -$250 + $300
= $50
Therefore, his current balance will be $50

Explain why the product of a non-0 rational number and an irrational number is irrational?
Answer:
An irrational number is a number that can not be written as the quotient of two integer numbers.
Then if we have:
A = a rational number
B = a irrational number.
Then we can write:
A = x/y
Then the product of A and B can be written as:
A*B = (x/y)*B
Now, let's assume that this product is a rational number, then the product can be written as the quotient between two integer numbers.
(x/y)*B = (m/n)
If we isolate B, we get:
B = (m/n)*(y/x)
We can rewrite this as:
B = (m*y)/(n*x)
Where m, n, y, and x are integer numbers, then:
m*y is an integer
n*x is an integer.
Then B can be written as the quotient of two integer numbers, but this contradicts the initial hypothesis where we assumed that B was an irrational number.
Then the product of an irrational number and a rational number different than zero is always an irrational number.
We need to add the fact that the rational number is different than zero because if:
B is an irrational number
And we multiply it by zero, we get:
B*0 = 0
Then the product of an irrational number and zero is zero, which is a rational number.

Write the slope-intercept form of the equation of each line.
Step-by-step explanation:
you look at how the line intersects with an integer point.
on the y-axis, the line has a value of -2 so it has a y-intercept value of -2
so the slope formula is rise/run.
As we can see on the graph, there is no line on the graph that truly lines up with a point besides (0,-2)
if we look at all of the slopes
from A,B,C, and D, and there are not any slopes besides d that are on the graph.
y=mx+b
m=slope
b=y-intercept
If we expand the graph a little bit we can see that the point (0,-2) goes up 7 and goes to the left of 4 units.
so the answer is D : y=-7/4x-2
----------------------------------------------------------------------
and since we go up and to the left or we go down and to the right that determines that the slope is negative.
If we started on a point on the y-axis, and started and went up and to the right or down and to the left.
Hope that helps :)
