Answer:
1/4
Step-by-step explanation:
The image/preimage scale factor can be found by considering the lengths of corresponding sides.
Q'R'/QR = (4-2)/(16 -8) = 2/8 = 1/4
The scale factor is 1/4.

7. The perimeter of a rectangular pool is 70 meters. If the width of the pool
is 12 meters, then find its length.
Answer:
23 meters
Step-by-step explanation:
You would subtract 24 from 70, and then divide by two.
70-24=46
46/2 = 23
Write an equation that represents the line. Use exact numbers
Answer: [tex]y=\frac{2}{3}x+1\frac{1}{3}[/tex]
Step-by-step explanation:
take 2 points and use slope formula to find slope
[tex]\frac{4-2}{4-1}[/tex][tex]=\frac{2}{3}[/tex]
take the slope and a point on the graph and use point slope formula to get equation in point slope intercept form
[tex]y-2=\frac{2}{3}( x-1)[/tex]
[tex]y-2=\frac{2}{3}x-\frac{2}{3}[/tex]
[tex]y=\frac{2}{3}x-\frac{2}{3} + 2[/tex]
[tex]y=\frac{2}{3}x+1\frac{1}{3}[/tex]
What is the answer to this Multi Step equation?
2y+29-8y=5
Answer:
Y=4
Step-by-step explanation:
Let's solve your equation step-by-step.
2y+29−8y=5
Step 1: Simplify both sides of the equation.
2y+29−8y=5
2y+29+−8y=5
(2y+−8y)+(29)=5(Combine Like Terms)
−6y+29=5
−6y+29=5
Step 2: Subtract 29 from both sides.
−6y+29−29=5−29
−6y=−24
Step 3: Divide both sides by -6.
−6y/-6=-24/-6
y=4

Step-by-step explanation:
A scale drawing of triangle ABC has side lengths of 2 centimeters (cm), 4.8 cm, and 5.2 cm. The scale drawing was drawn using the scale of 1 cm=4 inches.
Raquel creates a different scale drawing of the original triangle ABC with the scale factor 116.
What are the side lengths in Raquel's scale drawing?
-1 in., 2.4 in., and 2.6 in.
-0.5 in., 1.2 in., and 1.3 in.
-8 in., 19.2 in., and 20.8 in.
-128 in., 307.2 in., and 332.8 in.
Step-by-step explanation:
I am not sure this is typed all correctly.
what I understand here :
there is an original triangle ABC in inches.
then, using the scale 1 cm = 4 inches a smaller triangle A'B'C' was created.
the side lengths of A'B'C' are 2cm, 4.8cm, 5.2cm.
due to the scale of 1 cm = 4 inches that means ABC has the side lengths 8 inches, 19.2 inches, 20.8 inches.
and now, another scaled triangle A"B"C" is drawn in inches based on ABC with a scan factor of 1/16 (is that correct ?).
that means that all side lengths are divided by 16 for the resulting triangle.
8 inches /16 = 0.5 inches
19.2 inches / 16 = 1.2 inches
20.8 inches / 16 = 1.3 inches
so, the second answer option is correct.

The area of a trapezoid is 65mm2, the top is
9mm long, the height is 11mm long.
Find the base of the trapezoid.
Answer:
[tex]2.\bar{81}mm[/tex]
Step-by-step explanation:
First the formula for find the are of a trapezoid is:
[tex]A = \frac{h(a+b)}{2}[/tex]
Where [tex]a[/tex] is the top, [tex]h[/tex] the height and [tex]b[/tex] the base measures.
Then we need to know what is the base ([tex]b[/tex]), for that isolate [tex]b[/tex] from the equation
[tex]2A = h(a+b)\\\frac{2A}{h} = a+b\\\frac{2A}{h} - a = b[/tex]
Then in the new equation replace the given values:
[tex]A = 65mm^2\\a = 9mm\\h = 11mm[/tex]
[tex]\frac{2 \cdot 65mm^2}{11mm} -9mm = b\\\frac{130mm^2}{11mm} -9mm = b\\11.\bar{81}mm -9mm = b\\2.\bar{81}mm = b[/tex]
So the final answer is [tex]2.\bar{81}mm[/tex]

A student ran a distance of 33 miles each day for 5 days. Then the student ran a distance of 4 miles each day
for the next 5 days.
What was the total distance in miles the student ran during these 10 days?
10days = ... miles
= 5days × 2
= 33 × 2
= 66miles

MARK ME BRAINLIEST PLSSSSfind the 10th term
FORMULA: Tn=a+d(n-1)
Answer:
T₁₀ = 23
Step-by-step explanation:
The nth term of an arithmetic sequence is
[tex]T_{n}[/tex] = a + (n - 1)d
where a is the first term and d the common difference
Here a = - 4 and d = T₂ - T₁ = - 1 - (- 4) = - 1 + 4 = 3 , then
T₁₀ = - 4 + (9 × 3) = - 4 + 27 = 23
Answer:
-4,-1,2,5 turn into consecutive terms
d=-1-(-4)
d=2-(-1)
d=5-2
d=-1-(-4) calculate the value
d=3
d=2-(-1)
d=5-2
So it is a Arethmetic Sequence
That's my answer hope it helps
The price of Stock A at 9 AM was $12.73. Since then, the price has been increasing at the rate of $0.06 per hour. At noon, the price of Stock B was 13.48. It begins to decrease at the rate of $0.14 per hour. If the stocks continue to increase and decrease at the same rates, in how many hours will the prices of the stocks be the same?
Answer:
Let the hours when they equalize=h, then we have:
12.25 + .13h=13 - .09h
.13h + .09h=13 - 12.25
.22h=.75 divide both sides by .22
h=.75/.22
h=3 9/22, hours, when they will equalize.
The stock prices will be the same in 3.4 hours.
What is the equation?The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.
At 9 a.m., the price of Stock A was $12.73. Since then, the price has risen at a pace of $0.06 per hour. Stock B was trading at 13.48 at midday. It starts to fall at a pace of $0.14 each hour.
Let's assume the hours would be h when to equalize,
As per the given question, we can write the equation as:
12.25 + 0.13h = 13 - 0.09h
Rearrange the terms of h in the above equation,
0.13h + 0.09h = 13 - 12.25
Combine the likewise terms in the above equation,
0.22h = 0.75
Divide both sides by 0.22
h = 0.75/0.22
h = 3.4
Thus, the stock prices will be the same in 3.4 hours.

Bill keeps a colony of honeybees on his property. He has created an expression to represent
the number of honeybees that are in the colony t years after he decided to create the colony.
The expression Bill created is -1644 + 160t2 – 144.
After deciding to create the colony, it took a fair amount of time to prepare before actually
getting bees in his colony. After some time, the population in the colony started to decrease;
eventually Bill lost his colony.

Answer: 24.5 m² ( area)
Step-by-step explanation:
See , Total area of wall is given - length , 6m - width/breadth , 5m
so , Area of total wall = l x b = 6*5 = 30m²
so , there is a window whose length is 2 meters and breadth/width of 0.5m
so , Area of window = l x b = 1m²
So , area of door = length , 3 - Width/breadth- 0.5 m²
So , Area of door = 3* 1.5 = 4.5
Then the question wants us to find the area of the wall without counting window and door . So we can subtract the area of door and window from the area of the whole wall to get the area of the wall without the window and door .
= total area of wall - area of window and door
30m²-1m²-4.5
So as a result , we get a total area of the wall without the window and door to be painted as 24.5m²
