Answer:

∠1 = 40

Step-by-step explanation:

So due to the alternate interior angles theorem, angle 1 and angle 2 equal each other so:

2x + 20 = 3x + 10

subtract 2x from both sides

20 = x + 10

subtract 10 from both sides

10 = x

Now input 10 into the equation

2(10) + 20

20 + 20

40

Write the equation that represents the line shown.

Hyan has saved $300 more than two-thirds of the cost of the down
payment on a car. If he has $1240 saved, how much is the down payment?
algebra problem

Answers

Answer:

$1410

Step-by-step explanation:

Hyan has $1240 saved, which is equal to 2/3 of the down-payment, plus an additional $300

$1240-$300= $940

$940 is equal to 2/3 of the payment, in other words, it's two 1/3 payments, so we can split $940 into two to see how much is equal to 1/3 of the payment.

$940/2= $470 = 1/3

Three 1/3 equal 1 whole so we multiply $470 by 3 to find the amount of the whole payment

$470x3= $1410

Interpretation of axes and scales:

The horizontal axis (x-axis): There is time in seconds on the horizontal axis

Scale: 1 unit in the x-axis = 1 second

The vertical axis (y-axis): There is the distance in feet which is the height of the elevator from the ground on the horizontal axis

Scale: 1 unit in the y-axis = 20 feet

Interpretation of the origin:

The coordinate is represented by the point (0,0) in the graph. This means at time = 0 the height of the elevator =0, i.e the elevator is on the ground at the starting time.

Answer:

The inequality matches the graph is 2n + 5 ≤ 7 A

Step-by-step explanation:

Let us solve the question

From the given graph

∵ The arrow starts from 1 and pointed to the left (negative part)

∵ The starting point of the arrow is bold

∴ The sign of the inequality is ≤ (smaller than or equal)

→ That means the solution of the inequality is all the numbers ≤ 1

The solution of the inequality is n ≤ 1

→ Look at the choices and find which one has the sign ≤ and check if

  it will give the same solution or not

∵ The inequality is 2n + 5 ≤ 7

→ Subtract 5 from both sides

∴ 2n + 5 - 5 ≤ 7 - 5

∴ 2n ≤ 2

→ Divide both sides by 2

n ≤ 1

The inequality gives the same solution of the given graph

The inequality matches the graph is 2n + 5 ≤ 7

If Roger ran 5 miles in 150 minutes, Ryan ran 10 miles in 300 miles, and Rick ran 5 miles in 2 and ½ hours, who had the best rate of running(fastest time)?

Answers

Answer:

All three have same rate of running.

Step-by-step explanation:

Given that:

Distance covered by Roger = 150 minutes

Time taken by Roger = 5 miles

Distance covered by Ryan = 300 minutes

Time taken by Ryan = 10 miles

Distance covered by Rick = 2[tex]\frac{1}{2}[/tex] hours

Time taken by Rick = 2 miles

To find:

Who has the fastest rate of running?

Solution:

First of all, we need to convert the time in hours and then we need to apply the formula for relation between Speed, time and distance.

Then we can compare the Speed.

60 minutes = 1 hour

150 minutes = [tex]\frac{1}{60} \times 150 = 2.5\ hours[/tex]

300 minutes = 5 hours

Formula for Speed:

[tex]Speed = \dfrac{Distance}{Time}[/tex]

Rate of running (speed) of Roger = [tex]\frac{5}{2.5}[/tex] = 2 miles/hr

Rate of running (speed) of Ryan = [tex]\frac{10}{5}[/tex] = 2 miles/hr

Rate of running (speed) of Rick = [tex]\frac{5}{2.5}[/tex] = 2 miles/hr

Therefore, All three have same rate of running.

Answers

I would pick D but I’m not 100% sure

Answer: Choice C) [tex]\frac{\sin(23)}{6.2} = \frac{\sin(85)}{b}[/tex]

=========================================================

Explanation:

The angle opposite side b is 85 degrees. So we'll involve either the fraction [tex]\frac{\sin(85)}{b}[/tex] or [tex]\frac{b}{\sin(85)}[/tex]. In this case, we will use the first fraction. This is due to all of the answer choices having sine on top.

The other fraction must have sine on top as well.

The known side is AB = 6.2; the opposite angle is C = 23 which you find by solving A+B+C = 180 and plugging in A = 72 and B = 85.

So the other fraction we'll use is [tex]\frac{\sin(23)}{6.2}[/tex]

Overall, the proportion we can set up is

[tex]\frac{\sin(23)}{6.2} = \frac{\sin(85)}{b}[/tex]

which points to choice C as the final answer.

what is 1x+3y=18 in slope intercept form

Answers

Answer:

y = -x/3 + 6

General Formulas and Concepts:

Pre-Algebra

Equality Properties

Algebra I

Standard Form: Ax + By = C

Slope-Intercept Form: y = mx + b

m - slope b - y-intercept

Step-by-step explanation:

Step 1: Define

Standard Form:   x + 3y = 18

Step 2: Rewrite

Find slope-intercept form

Subtract x on both sides:                    3y = -x + 18Divide 3 on both sides:                       y = -x/3 + 6

Answer:

y=-3x+6

Step-by-step explanation:

slope int. form is y=mx+b

want to get y by itself, so subtract 1x

so you are left with 3y=-1x+18

then divide 3

left with y=-1/3x+6

simplified is y=-3x+6
