Answer:
see below
Step-by-step explanation:
The idea is you're trying to find quotient values that get you close to the dividend value when they're multiplied by the divisor.
In the left panel, you are basically looking at 8/3 ≈ 2. Since that is 8 tens, the partial quotient is 2 tens, or 20. The value of that multiplied by the divisor (3) is what gets subtracted from 87 for the next effort.
That difference (27) is the new dividend at the top of the right panel. The line below it (-27) is the result of multiplying the partial quotient by 3. Hence, that partial quotient on the top line must be 9. We want the difference at the bottom of the right panel to be zero.
__
In case you didn't know already that 87/3 = 29, you could work backwards. Starting from 0 at the bottom right, you would fill in the boxes above that, then copy the top box in that panel (27) to the difference at the bottom of the left panel. Of course, the middle number there must be 60 for the difference to be 27. That is 3·20, meaning the partial quotient at left on the top line is 20.

What is the equation of the line in slope-intercept form?
Write your answer using integers, proper fractions, and improper fractions in
simplest form
Answers
Answer:
The equation of the line in the slope-intercept form will be:
y = -7xStep-by-step explanation:
The slope-intercept form of the line equation
y = mx+b
where
m is the slope b is the y-interceptFrom the attached graph, taking two points
(0, 0)(-10, 70)Finding the slope between (0, 0) and (-10, 70)
[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\left(x_1,\:y_1\right)=\left(0,\:0\right),\:\left(x_2,\:y_2\right)=\left(-10,\:70\right)[/tex]
[tex]m=\frac{70-0}{-10-0}[/tex]
[tex]m=-7[/tex]
Determining the y-intercept:
We know that the value of y-intercept can be determined by setting x = 0, and determining the corresponding value of y.
From the graph, it is clear that:
at x = 0, y = 0
Thus, the y-intercept b = 0
Now, substituting m = -7 and b = 0 in the slope-intercept form
y = mx+b
y = -7x + 0
y = -7x
Therefore, the the equation of the line in slope-intercept form will be:
y = -7xSix less than 2 times a number is 50. What is the number?
Answers
Answer:
a + b = 50 (Two numbers total 50)
b = a - 6 (one number is 6 less than the other)
Since we have a value, we can use the substitution metod:
a + a - 6 = 50
Simplify:
2a - 6 = 50
From here, you should know how to isolate a variable--add 6 then divide by 2 in this case. That'll give you a, and you'll be able to use that to solve for b.
2(a) -6= 50
2a-6= 50
six goes and adds to 50 on the other side
2a = 56
divide both sides by 2
a= 28
final answer 28

Answer:
m∠AYB = 85°
m∠C = 50°
Step-by-step explanation:
By is the angle bisector of ∠ABC,
Therefore, m∠1 = m∠2 = 30°
m∠3 = 35°
m∠AYB + m∠YAB + m∠ABY = 180°
m∠AYB = 180° - [(m∠1 + m∠2) + m∠3]
= 180° - [(30° + 30°) + 35°]
= 180° - 95°
= 85°
m∠A + m∠B + m∠C = 180°
2(30°) + 2(35)° + m∠C = 180°
60° + 70° + m∠C = 180°
m∠C = 180° - 130°
m∠C= 50°

Cassie can run 1/2 mile in 1/6 of an hour. How far can she run in 1 hour?
Answers
To get from 1/6 hour to 1 hour .. we need to multiply by 6.
6 * 1/6 = 1
We will now also need to multiply her distance by 6
1/2 * 6 = 6/2 = 3
Now we know she runs 3 miles in one hour. Which is also her speed. 3mph
If it takes her 1/6 per hour to run half a mile. Let's see how long she can run in one hour.
To get from 1/6 hour to 1 hour .. we need to multiply by 6.
6 * 1/6 = 1
We will now also need to multiply her distance by 6
1/2 * 6 = 6/2 = 3
Now we know she runs 3 miles in one hour. Which is also her speed. 3mph
Your family is putting in a rectangular pool in the back yard. The pool's perimeter equals 28 feet. The contractor want the length to equal 5 more feet than 3 times the width. What will the width of your garden be?
Answers
Answer:
2.25 ft
Step-by-step explanation:
Perimter= 28ft
W= x ft
L= 3x+5
but
P=2L+2W
substitute
28=2*(3x+5)+2x
28=6x+10+2x
collet like terms
28=8x+10
28-10= 8x
18=8x
divide both sides by 8
x= 18/8
x=2.25 ft
Hence the width is 2.25 ft

Answer:

Step-by-step explanation:
Since its a right angle triangle we can use the pythogorean theorem, which is a^2 + b^2 = c^2
So if we apply it to this situation we get,
12^2 + b^2 = 20^2
144 + b^2 = 400
b^2= 400 - 144
b^2= 256
b= 16
So the answer is 16km

10. Find the width of the canyon.
13.
width = ?
22 m
15 m
160 m
I need help asap
Answers
Answer:
Therefore, the width of the canyon is 109.09 meters.
Step-by-step explanation:
* 160/22 = k (Scale Factor)
7.2727 = k
* Let x be the width of the canyon
x / 15 = k
x / 15 = 7.2727
x = 7.2727 (15)
x = 109.09 m
The width of the canyon is 109.09m.
The calculation is as follows:Here we assume x be the width of the canyon.
The k(Scale factor) should be
= [tex]160 \div 22[/tex]
k = 7.2727
So,
[tex]x \div 15 = k\\\\ x \div 15 = 7.2727[/tex]
x = 109.09 m

40x + 20y = 180
y - 180 = 20(x - 40)
y = 20x + 40
x = 40y + 20
y = 40x + 20
y - 40 = 20(x - 180)

b is y when x = 0
