Given the preimage and image, find the dilation scale factor
Answer:
1/2
Step-by-step explanation:
the dilation factor should be 1/2
if u count the dots on the sides of the preimage there are 2 dots that's the length if u count the dots on the real image it's 4therefore 2/4 to it's lowest term is 1/2 so 1/2 is the scale factorAnswer:
should be 1/2 as your answer

Step-by-step explanation:
We wish to estimate what percent of adult residents in a certain county are parents. Out of 300 adult residents sampled, 102 had kids. Based on this, construct a 95% confidence interval for the proportion p of adult residents who are parents in this county.
Answer:
The answer is "[tex]0.34 \pm 0.060[/tex]".
Step-by-step explanation:
Point estimate = Sample proportion [tex]= \frac{102}{300}= 0.34[/tex]
For [tex]95\%[/tex] confidence, [tex]z = 1.96[/tex]
Hence,
Margin of error[tex]= 1.96 \times \sqrt{0.34\times \frac{0.84}{300}}=1.96 \times 0.0308 = 0.060[/tex]
Therefore,
Confidence interval in the tri-equality form:
[tex]\to 0.34 - 0.060 < p < 0.34 + 0.060\\\\\to 0.28 < p < 0.4[/tex]
Confidence interval using point estimate and margin of error:
[tex]p = 0.34 \pm 0.060[/tex]

A fundraiser was held to split the profits between the 9 baseball players. How much money was raised if each player earned $326? Construct a division equation to represent the situation. Make sure to identify and label your variable. Solve for the variable and describe your answer. Show your work and prove your solution to be correct.
Answer:
Part 1
The number of baseball players that are to split the profits = 9 baseball payers
The amount of money each player earned = $326
Let x represent the total amount of money raised, and given that each baseball player received equal amount of the profits we have the following division equation;
[tex]The \ division \ equation \ is , \dfrac{x}{9} = \$ \, 326[/tex]
Part 2
Solving for the variable, gives;
x = 9 × $ 326 = $2,934
The amount of profits from the fundraiser, x = $2,934
Part 3
The amount, A, each of the 9 players will earn from the profit of $2,934 raised in the fund raiser is given as follows;
A = $2,934/9 = $326
∴ The amount each of the 9 players will earn, A = $326, therefore the answer corresponds to the value in the question and is therefore, correct

There is a distance marker every 100 m and a pole every 80 m along a straight road. There is a distance marker and a pole together at the start of the road. How far along the road will there be a distance marker and a pole together again?
Answer:
At a distance of 400 m.
Step-by-step explanation:
From the information in the given question, a distance marker and pole are together at the start of the road.
Thus,
the distance marker would mark the road 100 m, 200 m, 300 m, 400 m, 500 m etc.
Also,
the pole would be located 80 m, 160 m, 240 m, 320 m, 400 m, 480 m etc.
Comparing the distance of location of the marker and pole, it would be observed that the next location where the two would be together is 400 m from the starting point.
Therefore, there would be a distance marker and a pole together at 400 m from the stat of the road.

A piece of wire is bent to form a square of area 121 cm?
Calculate:
a)
The length of each side of the square
b)
The perimeter of the square
Step-by-step explanation:
that is really a problem ?
come on !
you know, the area of a square is side length × side length = length²
that is basically all of us learn as the very first thing when we are learning about squaring and multiplication.
how do we get the regular side length out of length² ?
we pull the square root. you have a calculator (at least on your computer, cell phone,...).
sqrt(121) = .... .... .... 11 ! tada !
and the perimeter of a square ... you really have to ask ?
it is the way all around the whole square. you need to go along every one of the 4 sides.
so, it is side length × 4 = 11×4 = 44 cm
again - you really needed help with THAT ?
What is the value of x in the equation 2x + 3y = 36, when y = 6?
8
9
27
36
Answer:
x = 9
Step-by-step explanation:
we can plug in the given value for y into the equation to find x
2x + 3y = 36
2x + 3(6) = 36
2x + 18 = 36
2x = 18
x = 9
Answer:
x = 9
Step-by-step explanation:
2x + 3y = 36
Let y=6
2x+3(6) = 36
2x+18 = 36
Subtract 18 from each side
2x+18-18 =36-18
2x = 18
Divide by 2
2x/2 =18/2
x = 9
In ΔABC, ∠A = 50° and the external bisectors of ∠B and ∠C meet at O as shown in figure. The measure of ∠BOC is
Answer:
17
Step-by-step explanation:
Look at Triangle ABC, The rays meet at line BC and they are both from the interior point A. So this means that AB=AC. This makes ABC a isosceles triangle. Using the isosceles triangle theorem, Angle B and Angle C measure is equal to each other so
[tex]50 + x + x = 180[/tex]
[tex]50 + 2x = 180[/tex]
[tex]2x = 130[/tex]
[tex]x = 65[/tex]
This means angle b and C of the triangle ABC measure is 65.
External bisector bisect a figure that it makes the original angle split into half that they are equal to each other.
This means the angle below Angle B and angle C measure is 32.5. We can find the measure of Angle B and C in triangle BOC. This is a isosceles triangle as well so
[tex]32.5 + 65 + x = 180[/tex]
[tex]98.5 + x = 180[/tex]
[tex]x = 81.5[/tex]
Angle C is 81.5 as well so
[tex]81.5 + 81.5 = 163[/tex]
Find angle o
[tex]180 - 163 = 17[/tex]

4. If 8 out of 25 snacks are healthy, how many healthy snacks will there be per 100 snacks total?
Answer:
32 of them would be unhealthy. this is because 25 times 4 equils 100, so 8 times 4 equils 32.
Answer:
32 healthy snacks
Step-by-step explanation:
-set up an equivalent fraction to keep the same proportion
8 healthy / 25 snacks = ? healthy / 100 snacks
-solve for ? healthy
8/25 = ?/100, cross multiply
25 * ? = 8*100 , divide both sides by 25
? = 800/25 = 32 healthy snacks
* you can also think that 100 is 25 four times,
so the healthy snacks are 8*4 =32

Kay must re-carpet her circular den. If the diameter of the
den is 6 yards, what is the total square yardage of carpet
that is needed?
Answer:
28.26² yards
Step-by-step explanation:
Diameter is 6.
Radius=Diameter/2. r=6/2
Area=Pi*Radius²
I'll just use 3.14 for pi
Area=3.14*3²
3²=9 3.14*9=28.26
so the answer 28.26²
Find the 20th term from the last term of the AP 34 , 32 30,.........., 10.
Answer:
-30
Step-by-step explanation:
Tn = a1 + (n-1)d = 34 + (-2)(n-1) = 34-2n+2 = 36-2n
hence,
10= 36-2n
2n = 36
n = 13
20 terms from the last term would be 13+20 = 33
T33 = 36-2(33) = -30
Find the volume of a cone with a
radius of 10 and a height of 7. Use 3.14 for n and
round the answer to the nearest whole number.
Answer:
Step-by-step explanation:
Volume of a cone formula is
[tex]V=\frac{1}{3}\pi r^2h[/tex] where r is radius and h is height. Filling in:
[tex]V=\frac{1}{3}(3.14)(10)^2(7)[/tex] and doing all the math on that and rounding gives us
V = 733 units cubed
Find the vertical asymptotes of the function (x-1)(x-3)^2(x+1)^2/(x-2)(x+2)(x-1)(x+3)
Answer:
x=2, x=-2, x=-3
Step-by-step explanation:
-check if anything simplifies
(x-1)(x-3)²(x+1)² / (x-2)(x+2)(x-1)(x+3), simplify (x-1)
(x-3)²(x+1)² / (x-2)(x+2)(x+3)
-make the denominator 0 to find the asymptotes
(x-2)(x+2)(x+3) = 0
(x-2) =0 gives x = 2 asymptote
(x+2) =0 gives x= -2 asymptote
(x+3) = 0 gives x=- 3 asymptote

Find the value of x.
A. 31
B. 25
C.5
D. 11
Answer:
D) 11
Step-by-step explanation:
Explanation:
Segment AC is the midsegment of the trapezoid (since A and C are midpoints of DE and FB respectively)
This means that AC is the average of the two parallel bases EB and DF
AC = (EB + DF)/2
x = (9 + 13)/2
x = 22/2
x = 11
The value of x is 11.
What is mid point theorem?The midpoint theorem states that the line segment joining the midpoints of any two sides of a triangle is parallel to the third side and equal to half of the length of the third side. This theorem is used in various places in real life, for example in the absence of a measuring instrument, we can use the midpoint theorem to cut a stick into half.
In math, we also have a midpoint theorem formula which has its applications in coordinate geometry. It can also be known as the midpoint theorem of a line segment. It states that if we have a line segment whose endpoints coordinates are given as (x1, y1) and (x2, y2), then we can find the coordinates of the midpoint of the line segment by using the formula given below:
Let (xm, ym) be the coordinates of the midpoint of the line segment. Then,
(xm, ym) = ( (x1 + x2)/2 , (y1 + y2)/2 )
This is known as the midpoint theorem formula.
As, A and C are midpoints of DE and FB respectively
AC = (EB + DF)/2
x = (9 + 13)/2
x = 22/2
x = 11
