You and your friend are trying to meet up at the park. You are currently 256 m directly west from the centre of the park. Your friend is currently 388 m directly north from the centre of the park. What is the distance between you and your friend?
Answers
Answer:
The distance between the two is 465 meters
Step-by-step explanation:
We first need to set up a triangle that shows the relative position and distances of the two friends
Please check attachment for this
To get this distance, which represents the hypotenuse of the triangle, we make use of Pythagoras’ theorem
Mathematically;
Pythagoras’ theorem states that the square of the hypotenuse equals the sum of the squares of the two other sides
Thus;
D^2 = 256^2 + 388^2
D^2 = 216,080
D = √216,080
D = 464.84 which is approximately 465 m

Step-by-step explanation:
Timmy wants to buy a scooter and the price was $150. When he goes to the store a
second time, he found that the price was marked down by 15%. Then when he gets to the
register the cashier tells him today only he gets an additional 10% off the sales price. What is
the final cost of the scooter including the discounts?
Answers
Answer:
112.5
Step-by-step explanation:
total discount: 25%
Answer:
Step-by-step explanation:
150*15% off =22.50 off total 127.50. Then he gets the 10% off 127.50*10%= 12.75 off total cost $114.75
It may look like 25% off at once, but most stores will do the discounts separately so they don't lose too much money.
Use the zero product property to find the solution to the equation 6x^2-5x=56
Answers
Answer:
x = -8/3 or 7/2
Solution:
6x^2 - 5x = 56
6x^2 - 5x - 56 = 0
6x^2 -21x +16x - 56 = 0
3x(2x-7) + 8(2x-7) = 0
(3x + 8)(2x-7) =
3x + 8 = 0 or 2x - 7 = 0
x = -8/3 or 7/2

4 ice cream cones cost $6. At this rate, how much do 7 ice cream cones cost?
this is a test for middle schoolers but anyone is free to answer
Answers
Answer:
$42
Step-by-step explanation:
Equation: y = 6x
x = number of ice cream cones
y = 6(7) = 42
Hi! I believe your answer is $10.50. If it's $6 for 4 ice cream cones, divide 6 by 4 and you'll get 1.5, or $1.50 per ice cream cone. For 7 ice cream cones, multiply the unit rate ($1.50 per ice cream cone) by 7. The total cost is $10.50. I hope this helps you! Good luck and have a great day. ❤️✨

find an equation for the line below
Answers
Answer:
[tex]y+1=\frac{-2}{3} (x+4)[/tex]
Step-by-step explanation:
you can use the equation point-slope of a line
(y-y1)= m(x-x1)
m is the slope =rise /run
to get from the lower point on the line to the other you rise 4 units and run -6 units so m= -4/6= -2/3
now that you have the slope pick you need one point
pick any poin on the line for example (-4, -1)
now you substitute into the point-slope equation point (-4,-1) and slope -2/3
(y+1)= -2/3(x+4)
in standard form will be
y=[tex]\frac{-2x}{3} -\frac{2*4}{3} -1[/tex]
y=[tex]\frac{-2x}{3}- \frac{5}{3}[/tex]

Eleven digits for toll calls became standard in all of North America by the end of 1994 to allow introduction of "interchangeable NPA codes" – area codes that did not have a 0 or 1 as the middle digit and could therefore be confused with the central office code – after January 1, 1995.

What is the decimal equivalent of 7/10?
Answers
Answer:
0.7
Step-by-step explanation:
zero and seven TENths. the place value of the 7 is tenths so on the bottom of the fraction will be 10. i'm bad at explaining so sorry.
the decimal equivalent of 7 / 10 is 0.7.
To find the decimal equivalent of 7 / 10, we divide the numerator ( 7) by the denominator ( 10).
When we perform the division, 7 ÷ 10, we get 0.7.
Therefore, the decimal equivalent of 7 / 10 is 0.7.
In decimal form, the number 0.7 represents 7 tenths or 7 parts out of 10. It indicates that the numerator ( 7) is 7 / 10th of the denominator ( 10). This decimal representation makes it easier to compare the fraction with other decimal numbers and perform arithmetic operations using decimals.

Write an equation in slope intercept form of the line the passes through the given points.
(5,4)(15,2)
Answers
Answer:
y = -1/5x + 5
Step-by-step explanation:
Since this is written in slope-intercept form, you need to follow this form:
y = mx + b
(where m is the slope and b is the y-intercept)
To find the slope, you need to do (rise/run) or (change in y/change in x) with (5, 4) and (15, 2):
(4 - 2) / (5 - 15)
= 2 / -10
= -1/5
so m = -1/5
To find the y-intercept, you just need to plug one of the points into the equation with the slope:
y = -1/5x + b
= 4 = -1/5(5) + b
= 4 = -1 + b
= b = 5
so b = 5
Now, you put it all together:
y = -1/5x + 5
A cyclist travels 17 km from home to the park.
She leaves home at 17:15 and arrives at the park at 17:45.
What is her average speed in km/h?
Answers
Answer:
34 km/h
Step-by-step explanation:
speed = distance/time
Distance = 17km
Time = 0.5 or 1/2 hours because it's 30 minutes between 17:15 to 17:45, and 30 minutes is a half of an hour and you want km over hours
So
speed = 17/0.5
speed = 34 km/h
The population of mexico has been increasing at an annual rate of 1.7%. If the population of mexico was 104900000 in the year 2003, predict the population of mexico in 2019
Answers
Answer: 137,375,958
Step-by-step explanation:
Exponential growth equation:
[tex]y=A(1+r)^x[/tex] , where A = initial population , x= time , r =rate of growth.
As per given: r = 1.7% = 0.017
Population of Mexico in 2003 : A= 104900000
In 2019 , x = 2019-2003 = 16
Population in Mexico : [tex]y=104900000 (1+0.017)^{16}=104900000 (1.017)^{16}[/tex]
[tex]=104900000 (1.30958968823)\approx137375958[/tex]
Population of Mexico in 2019 = 137,375,958
