Answer:
Step-by-step explanation:
m∠X + m∠Y + m∠Z = 180 {angle sum property of triangle}
3x + 5 + 40 +4x - 5 = 180
3x + 4x + 5 + 40 -5 = 180 {Combine like terms}
7x + 40 = 180 { subtract 40 from both sides}
7x = 180 - 40
7x = 140
x = 140/7
x = 20
m∠X = 3x + 5
= 3*20 + 5
= 60 + 5
m∠X = 65
m∠Z = 4x - 5
= 4*20 - 5
= 80 - 5
m∠Z = 75

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

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.

what is 1x+3y=18 in slope intercept form
Answers
Answer:
y = -x/3 + 6
General Formulas and Concepts:
Pre-Algebra
Equality PropertiesAlgebra I
Standard Form: Ax + By = C
Slope-Intercept Form: y = mx + b
m - slope b - y-interceptStep-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 + 6Answer:
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
in an examination 40% students passed in math only, 30% passed in Science only, and 10% students failed in both the subjects .if 400 students passed in Science find the total number of students by drawing a Venn diagram.
Answers
Answer:
40% of the student is 160
30% of the students is 120
10% of the students is 40
the remain is ___
160 + 120 + 40= 320
400 -320 = 80
meaning 160 students passes only math (40%). 120 students passed on science (30%). 40 students fail both subjects (10%) and 80 students passes both subjects (20%)

You throw a ball into the air from a height of 5.5 feet with an
initial vertical velocity of 40 feet per second. Use the vertical
motion model, h = -16t2 + vt +s, where v is the initial

calculate the maximum height of the ball. Round your answer
to the nearest tenth if necessary.

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
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.

Triangle GHI with vertices G(4, 1), H(5, -4), and I(2, -8) REFLECTED over the line y = x.
Answers
Answer:
[tex]G' = (1,4)[/tex]
[tex]H' = (-4,5)[/tex]
[tex]I = (-8,2)[/tex]
Step-by-step explanation:
Given
[tex]G = (4,1)[/tex]
[tex]H = (5,-4)[/tex]
[tex]I = (2,-8)[/tex]
Reflection: [tex]y = x[/tex]
Required
Determine the coordinates of G'H'I'
The following applies when a line A is reflected over [tex]y = x[/tex]
[tex]A = (x,y)[/tex]
[tex]A' = (y,x)[/tex]
i.e, we simply swap the positions of x and y
So, for:
[tex]G = (4,1)[/tex]
[tex]H = (5,-4)[/tex]
[tex]I = (2,-8)[/tex]
The reflections are:
[tex]G' = (1,4)[/tex]
[tex]H' = (-4,5)[/tex]
[tex]I = (-8,2)[/tex]
