Answer:
10 red pencils because 10 is double 5 so it would be 5:10 which simplifies to 1:2
Answer:
10
Step-by-step explanation:
ratio 1 : 5
for 5 blue pencils ratio = 1
x red pencils ratio. = 2
simply 5B = 1
xR = 2
5B × 2 = R
R = 10
Therefore 10 red pencils are required
A line goes through the points (7, 3) and (11, 5). What is the equation of the line? Answer quick pls.
Step-by-step explanation:
slope = ( y2-y1) / (x2-x1)
= (5-3) / (11-7)
= 1/2
y= mx+ b
m = slope
5 = 11/2 + b
5 - 5.5 = b
b = -0.5
the equation y = 1/2(x) - 0.5
The equation of line is x-2y =1
How do you find equation of a line?To find an equation of a line given the slope and a point.Identify the slope.Identify the point.Substitute the values into the point-slope form, y − y 1 = m ( x − x 1 ) . y − y 1 = m ( x − x 1 ) .Write the equation in slope-intercept form.Slope-intercept form: The equation of line with slope m and making an intercept c on the y-axis, is y = mx + c.
Given coordinates are:
(7, 3) and (11, 5)
now, equation of line
(y- y1)= (y2-y1)/(x2-x1) *(x-x1)
y-3 =(5-3)/(11-7) *(x-7)
y-3= 2/4 * (x-7)
y-3= 1/2(x-7)
2y-6= x-7
x-2y =1
Hence, the equation of line is x-2y =1.

Answer:
y = x - 8
Step-by-step explanation:
There's no magic method to doing these, and problem 21 makes it harder to see a pattern by using inputs that are not consecutive integers (like problem 20 does)!
Looking at inputs 20 and 21, the outputs are 8 less than the inputs. Check the other inputs and notice that the same pattern holds up.
A repair bill for a car is $648.45. The parts cost $265.95. The labor cost is $85 per hour. Write and solve an equation to find the number of hours of labor spent repairing the car
Answer:
( t - p ) / 85x = h
( t - 265.95 ) / 85x = h
648.45 - 265.95 / 85x = 3.32h
h = 3.32
Therefore ( t - p ) / 85x = 3.32
Step-by-step explanation:
648.45 - 265.95
282.50 /85
= 3.32 hrs
Finding equation to find hours can be shown as
( t - p ) / 85x = 3.32
How we found equation to find total
Parts = 19 x 14 - 5/100 = 266- 0.05
648.45 - 265.95 = 282.5
282.5/85 = 3.323 near to 3,233529
Labour = 85x = 17 (5 + x)
Equation = 17(5+ x) + 14(19) - 5/100 = 648.45 where x = 85
Equation = ( 85x x 3 1/3) + 265 - 19/20 = t
The repair bill is an illustration of a linear equation. The equation that represents the scenario is: [tex]648.45= 265.95+ 85\times x[/tex]
And the solution (i.e. number of hours) is: 4.5 hours
Given that:
[tex]Bill = 648.45[/tex]
[tex]Parts = 265.95[/tex]
[tex]Labour = \$85[/tex] per hour
Let the number of hours spent be x
So, the equation is:
[tex]Bill = Parts + Labour \times x[/tex]
This gives;
[tex]648.45= 265.95+ 85\times x[/tex]
Collect like terms
[tex]648.45-265.95= 85\times x[/tex]
[tex]382.5= 85\times x[/tex]
Divide both sides by 85
[tex]4.5 =x[/tex]
[tex]x = 4.5[/tex]
Hence, the equation is:
[tex]648.45= 265.95+ 85\times x[/tex]
And the solution (i.e. number of hours) is: 4.5 hours

If C is between B and D with BC = 8x+8, Cd = 6x-28 and BD = 10x + 24, Then find CD
Whats CD
Answer:
CD = 38
Step-by-step explanation:
Answer
BC = CD
And,
BC + CD = BD
8x + 8 + 6x - 28 = 10x + 24
14x - 20 = 10x + 24
14x - 10x = 24 + 20
4x = 44
x = 44/4
x = 11
CD = 6(11) - 28
66 - 28
38
Answer:
CD = 38
Step-by-step explanation:
We know that BC and CD will add up to equal BD so we can create a equation and solve for x.
(8x + 8) + (6x - 28) = 10x + 24
~Combine like terms
14x - 20 = 10x + 24
~Add 20 to both sides
14x = 10x + 44
~Subtract 10x to both sides
4x = 44
~Divide 4 to both sides
x = 11
~Now substitute into CD
6(11) - 28
66 - 28

Name a pair of vertical angles, a straight angle, and two acute angles
other than
Step-by-step explanation:
While there are no examples available, there is the room to understand each angle type you listed, vertical angles are angles that are opposite from each other, and they are congruent (they have the same angle in degrees) now, imagine that for vertical angles, they are in an X top and bottom are equal, and the two sides are equal. For a straight angle, that is usually two angles that are right angles (90 degrees) back to back, meaning when you add 90 and 90 degrees together, you get a straight line or a 180 degree angle. An example of an acute angle is any angle less than 90 degrees, that is a real number, so imagine 25, 40, and 60 as all acute angles.

What is the image point of (-8,9)(−8,9) after a translation right 3 units and down 1 unit?
Answer:
(-5,8)
Step-by-step explanation:
The left number represents the x-axis, the right one the y-axis. A translation to the right means in the positive direction on the x-axis, which is why we add 3 to -8 which gives us -5. Down on the y-axis is in the negative direction, which means we have to subtract 1 from 9, giving us 8.
Answer:
the answer is the same since it is the same numeral so in terms of y=mx+c and x1/y1 would be inversely proportional to x2/y2 which is perfectly direct proportional to x3/y3×2 and then dy over dx is the problem of integration so you use (x2/x3÷y2/y3)×x1^y1

Nina can braid 144 inches of rope in 3 hours find her unit rate round your answer to the nearest thousand
Answer:
48 inches
or
0.8 minutes
Step-by-step explanation:
To find the unit rate of inches per hour, divide 144 by 3.
144÷3=48
You don't need to round because there are no decimals.
To find the time to braid 1 inch, first multiply 3 by 60 (because there are 60 minutes in 1 hour).
3×60=180
Then divide 144 by 180.
144÷180= 0.8
You don't need to round because there are no thousandths.

2. Ifj(x) = x2 + 1, find j(a + 1).
Step-by-step explanation:
if you mean x multiply 2 :
j(x) = 2x + 1
j(a+1) = 2(a+1) + 1
= 2a+ 2 +1
=2a + 3
if you mean x to the power of 2
j(x) = x^2 +1
j(a+1) = (a+1)^2 + 1

Refer to the graphic novel frame below. The brochure says that the rope is 500 feet long. Jacob drew a triangle in the sand that is similar to the actual triangle formed by a parasailer and the boat. Use the properties of similar triangles to determine the parasailer's height above
To solve this problem use the property of similar triangles,
"Corresponding sides of the similar triangles are proportional"
By using this property, height of the parasailer is 160 feet.
From the figure attached,
In ΔPQR, a parasailer is a at point P and a boat is at R.Actual length of the rope PR = 500 ftJacob drew a similar triangle ABC in which parasailer is at A and the boat is at C.Let the height (PQ) of the parasailer = x ft
Height of the parasailer AB = 25 ft.
And the length of the rope AC = 2.5 ft.
Since, both the triangles ΔABC and ΔPQR are the similar triangles, their corresponding sides will be proportional.
[tex]\frac{AB}{PQ}=\frac{AC}{PR}[/tex]
[tex]\frac{2}{x} =\frac{2.5}{200}[/tex]
[tex]x=\frac{200\times 2}{2.5}[/tex]
[tex]x=160[/tex] ft
Therefore, height of the parasailer is 160 feet.
