Answer:
Circumference of circle 1 : Circumference of circle 2 = 1 : 2
Step-by-step explanation:
Circumference of a circle = πD, where D is the diameter.
Diameter of circle 1 = 1.125
Circumference of circle 1 = π x 1.125
Diameter of circle 1 = 2.25
Circumference of circle 1 = π x 2.25
Circumference of circle 1 : Circumference of circle 2 = 1 : 2

w/8 - 4 = 20
add 4 on each side and divide by 8
subtract 4 on each side and multiply by 8
add 4 on each side and multiply by 8
subtract 4 on each side and divide by 8
Answer:
128Step-by-step explanation:
Step one:
given the expression w/8 - 4 = 20
the first operation is to isolate the term that has w by adding 4 to both sides
w/8 - 4+4 = 20+4
w/8 = 16
Required
the value of w
Step two:
the next step is to cross multiply
w=16*8
w=128
Suppose (ideally) a hammer claw moves a distance of 0.10 meters to remove a nail. If a resistance force of 1500 N is exerted by the claw, and you move the handle of the hammer 0.5 meters, what is the effort force?
Answer:
7500 N
Step-by-step explanation:
Given that,
A hammer claw moves a distance of 0.10 meters to remove a nail.
Resistance force, F = 1500 N
The person move the handle of the hammer 0.5 m
We need to find the effort force. Let it is F'. The mechanical advantage is given by :
[tex]m=\dfrac{effort}{resistance}=\dfrac{d_i}{d_o}[/tex]
Where [tex]d_i\ \text{and}\ d_o[/tex] are input and output distance respectively.
[tex]m=\dfrac{F'}{F}=\dfrac{0.1}{0.5}\\\\\dfrac{1500}{F}=\dfrac{0.1}{0.5}\\\\\dfrac{1500}{F}=0.2\\\\F=7500\ N[/tex]
So, the effort force is 7500 N.

Answer:
m<ACD = 90
m<CDB = 126
m<EDB = 54
m<CDE = 180
Step-by-step explanation:
Well you have the right girl! *In honors geometry you can trust me!
Ok first thing...We already know
B = 54
A = 90
D = 54 (It's the Alternate interior angle of B)
C = 90
m<ACD = 90 (C = 90)
m<CDB = 126 (D = 54 ------> 180-54= 126)
m<EDB = 54 (Alternate Interior angle of B)
m<CDE = 180 (It is a straight line)

find the length of a diagonal AB in the rectangular prism
Hi there!
[tex]\large\boxed{AB = 32.60 in}[/tex]
Find the length of AB by finding the length of its base:
We can use sine to solve for the length of the Hypotenuse of the triangle located in the base:
sin = O / H
sin 50° = 24 / H
h * sin 50° = 24 ----> h = 24 / (sin 50°)
h ≈ 31.33 in
Use the Pythagorean Theorem to solve for the length of the diagonal since we have solved for the base of the triangle:
c² = a² + b²
c² = 31.33² + 9²
c² = 1062.57
c ≈ 32.60 in
AB = 32.60 in
Writ an equation of a parabola that has a vertex (1,3) and passes through the point (2,5)
Answer:
y=2x+1
Step-by-step explanation:
Please look at number 10. from the slope and write the equation for me
Answer:
y = 8x + 38
Step-by-step explanation:
To find the slope we set up y = mx + b and plug m (our slope) in and then plug in the point into x and y to find b (our y-intercept)
y = mx + b
y = 8x + b
6 = 8(-4) + b
6 = -32 + b
+32 +32
38 = b
So using our slope and our intercept we have our slope intercept
y = mx + b
y = 8x + 38
Hope this helps :)
Answer:
y - y1 = m(x - x1)
y - 6 = 8(x - (-4))
y - 6 = 8(x + 4)
y - 6 = 8x + 32
y = 8x + 32 + 6
y = 8x + 38
Step-by-step explanation:
First you input the given values ( m = 8 and (-4, 6)) into the point-slope equation.
After that, you multiply the 8 by the two terms inside the parentheses, giving you 8x and 32.
Then you add 6 to both sides of the equation to isolate the y.
The slope-intercept equation ends up looking like this: y = 8x + 38
Hope this helps :)

6x + 3y = 54
How do i find the variable
Answer:
there are two variables x and y which variable do u need to find or do u need it in point slope form
Answer:
Simplifying
6x + 3y = 54
Solving
6x + 3y = 54
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-3y' to each side of the equation.
6x + 3y + -3y = 54 + -3y
Combine like terms: 3y + -3y = 0
6x + 0 = 54 + -3y
6x = 54 + -3y
Divide each side by '6'.
x = 9 + -0.5y
Simplifying
x = 9 + -0.5y

ax + bx = C
What’s the answer
Answer: Sure,
Step-by-step explanation:
The form ax^2 + bx + c = 0 is called standard form of a quadratic equation. Before solving a quadratic equation using the Quadratic Formula, it's vital that you be sure the equation is in this form. If you don't, you might use the wrong values for a, b, or c, and then the formula will give incorrect solutions.
Answer: That is standard form.

find the slope of the line through the pair of points (-4,12) , (-4,11)
is it undefined, 1, 0, or -1?
Answer:
Pretty sure its undefined
Step-by-step explanation:
Answer:
Undefined
Step-by-step explanation:
Looking at the change in x's theres no variation which means this is a vertical line, thus therefore this is an undefined line as the rise over the run or the change in y over the change in x will result in a divide by 0 situation making it (-4, all real numbers) aka undefined.
slope = rise/run = change in y/change in x = (y2-y1)/(x2-x1)
Hope this helps :)

If M is in the interior of ∠RTD, m∠RTM = 40°, and m∠RTD = 65°, then m∠MTD = .
Answer:
MTD = 75
Step-by-step explanation:
RTD + RTM + MTD = 180
65 + 40 + MTD = 180
105 + MTD = 180
Subtract 105 from both sides.
MTD = 75

When two straight lines or rays intersect at a shared endpoint, an angle is generated. The measure of the angle ∠MTD is equal to 15°.
What is an angle?When two straight lines or rays intersect at a shared endpoint, an angle is generated. An angle's vertex is the common point of contact. Angle is derived from the Latin word angulus, which means "corner."
Given that point M is in the interior of ∠RTD. Also, the measure of ∠RTM=40°, and ∠RTD = 65°.
Now, since the two angles together form ∠RTD, therefore, we can write,
∠RTD = ∠RTM + ∠MTD
65° = 40° + ∠MTD
∠MTD = 65° - 40°
∠MTD = 15°
Hence, the measure of the angle ∠MTD is equal to 15°.
