Find the distance between the two points rounding to the nearest tenth (if necessary)
(8,7) and (1,-2)
Answers
Answer:
≈ 11.4
Step-by-step explanation:
Calculate the distance using the distance formula
d = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]
with (x₁, y₁ ) = (8, 7) and (x₂, y₂ ) = (1, - 2)
d = [tex]\sqrt{(1-8)^2+(-2-7)^2}[/tex]
= [tex]\sqrt{(-7)^2+(-9)^2}[/tex]
= [tex]\sqrt{49+81}[/tex]
= [tex]\sqrt{130}[/tex]
≈ 11.4 ( to the nearest tenth )

Solve for x
x+7y=14
X=________
Answers
Answer:
x equals 14 - 7y
Step-by-step explanation:
x + 7y = 14
From this, take 7y to the other side. On shifting it to the other side of the equation, its sign changes to negative.
x = 14 - 7y
Then, we get x equals 14 - 7y.

The train is travelling with the speed of 90km/hr. What is the distance covered in 2min?
Answers
We are given:
Speed of the train = 90 km/h
Converting the speed to km per minute:
[tex]90\frac{km}{h}* \frac{h}{60 min}[/tex] [since 1 hour = 60 minutes, h/60 minutes is equal to 1]
The 'h' in numerator and denominator will cancel out
90km / 60 min
1.5 km/min
Distance travelled in 2 minutes:
Distance = Speed * time
Distance = [tex]1.5\frac{km}{min}* 2 min[/tex]
Distance = 3 km

Can anyone help ? I’m bad at math
Answers
Answer:
Step-by-step explanation:
First you need the third angle (C).
<C + 89 + 45 = 180 All triangles = 180 degrees. Combine the left terms.
<C + 134 = 180 Subtract 134 from both sides
<C = 180 - 134
<C = 46
Next, Let BA = x
x/Sin(46) = 15/Sin(89)
x = 15*sin(46) / Sin(89)
Sin(46) = 0.7193
Sin(89) = 0.9998
x = 0.7193 * 15 / 0.9998
x = 10.7911
Note
When you are studying this material, you should note 2 things.
The first is that you are dealing with 2 ratios that are equal to each other.The second is, the side is always opposite the angle in the triangle. The two are connect. Side c = 15. It is opposite the 89o angle.A boy has a weekend job advertising an upcoming play. He has 2 options for being paid. Option A is an hourly wage of $7.00.

Step-by-step explanation:
Given that :
24 / 18 = 4 / 3 = 1.333
Comparing the options solutions for the options given :
3/9 ÷ 2/8 = 3/9 * 8/2 = 24 / 18 = 1.333
4/9 ÷ 2/6 = 4/9 * 6/2 = 24/18 = 1.333
5/6 ÷ 3/4 = 5/6 * 4/3 = 20 / 18
8/3 ÷ 6/3 = 8/3 * 3/6 = 24 / 18 = 1.333
Hence, expressions which are equal are :

2000 restaurants will grow about 3% every year, what is the equation that represents it. Y = restaurants and t = years
Answers
Answer:
Y= PV*(1 + g)^t
Step-by-step explanation:
Giving the following information:
Number of Restaurants (PV)= 2,000
Growth rate (g)= 3%
To calculate the number of restaurants after t years, we need to use the following formula:
Y= PV*(1 + g)^t
For example, for 10 years:
Y= 2,000*(1.03^10)
Y= 2,688
