Answer:
A) length = 9cm, width = 4 cm
Step-by-step explanation:
The key word "times" refers to multiplication, so if you're trying to find dimensions at 1/4 times its original size, you need to multiply the original dimensions by 1/4.
l = 36
new l = 36 (1/4)
= 36/4
= 9 cm
w = 16
new w = 16 (1/4)
= 16/4
= 4 cm

Which weighs more: a watermelon that weighs 3.4 kilograms or a baby that weighs 9 pounds? Explain your reasoning. Note: 1 pound is about 0.45 kilograms.
Answers
Answer:
The baby weighs more than the watermelon
Step-by-step explanation:
1 pound is about 0.45 kilograms. So there are 3.4 kilograms (3400 grams) which will be 7.50 lbs rounded after converting. 7.50 pounds is less than 9 pounds.
5. Solve for q if 5q - 21 /14= 1.
Answers
q = 0.5
5q - 21/14 = 1
First add 21/14 to both sides to get:
5q = 1 21/14
Simplify the right side:
21/14 = 3/2 = 1 1/2
Now you have 5q = 2 1/2
Divide both sides by 5:
q = 1/2
The following exchange rate is given: £1 = 1.33 dollars. Convert £8 into dollars.
Answers
If £1 = $1.33, £8 is $10.64.
What is a unit rate?It is the quantity of an amount of something at a rate of one of another quantity.
In 2 hours, a man can walk for 6 miles
In 1 hour, a man will walk for 3 miles.
We have,
£1 = $1.33
Multiply 8 on both sides.
£8 = 8 x $1.33
£8 = $10.64

Suppose that 8% of all cars produced at Plant A have a certain defect, and 5\% of all cars produced at Plant B have this defect. A quality control manager takes separate random samples of 150 cars from each plant. The manager will then look at the difference (A - B) between the proportions of cars with the defect in each sample. What will be the shape of the sampling distribution of the difference in sample proportions, and why?
Answers
Answer:
The answer is "Choice d"
Step-by-step explanation:
Please find the complete question in the attached file.
Faulty factory cars in a plant [tex]A = 8\% \ of\ 150 \ = 12 > 10[/tex]
Faulty factory cars in a plant [tex]B = 5\% \ of \ 150 = 7.5 < 10[/tex]
This condition of the normal distribution is not met so because the number of negative cars from plant B is less than 10, that's why the choice d is correct.
Answer: D
Not normal, because we expect fewer than 10 defective cars in Plant B. [tex].05*150=7.5[/tex]

Answer:
The trees will be the same size in 12 years
Step-by-step explanation:
given the 3-foot tree can grow 1.5 feet per year
given the seeds can grow 1.75 feet per year
The trees will be the same size but it will take a while To find out how long that take we set up an equation to be
3 + 1.5x = 1.75x
3 = 0.25x
x = 12
x represents for years it take
Answer:
After 12 years both will be in same height
Step-by-step explanation:
Let 'x' be the number of years .
After 'x' years both will be in same height
Genevieve:
Rate of growth per year = 1.5 ft
Rate of growth after 'x' years = 1.5 * x = 1.5x
Height of tree after 'x' years = 3 + 1.5x
Marcus:
Rate of growth per year =1.75 ft
Rate of growth after 'x' years = 1.75 * x = 1.75x
Height of tree after 'x' years = 1.75x
After 'x' years both will be in same height
1.75x = 3 + 1.5x
1.75x - 1.5x = 3
0.25x = 3
x = [tex]\frac{3}{0.25}[/tex]
[tex]x =\frac{3*100}{0.25*100}=\frac{300}{25}[/tex]
x = 12

Answers
Answer:
1. Y = -4/3
2. 2x = 2y + 10
Step-by-step explanation:
1. y =− 2y − 4
Step 1: Add 2y to both sides.
y + 2y = −2y − 4 + 2y
3y = −4
Step 2: Divide both sides by 3.
3y/3 = -4/3
y = -4/3
2. solve for x
y=1/2x-5
Step 1: Flip the equation.
1/2x−5=y
Step 2: Add 5 to both sides.
1/2x−5+5=y+5
1/2x=y+5
Step 3: Divide both sides by 1/2.
1/2x/1/2=y+5/1/2
x=2y+10

Step-by-step explanation:
Ella's name appears on the table 2/10 times, so we can multiply the denominator to make it 1000.
10x100 = 1000
If we multiply the denominator by 100, we must do the same to the numerator,
2x100=200
In 1000 draws Ella's name can be expected to come about 200 times.
What is an experiment?An experiment is a way of determining how things may work.
From small sample space of experiments or models, we can assume the result of a larger sample space or models.
From the given table we observe that Ella's name came 2 times out of 10 random draws.
∴ In (10×100) = 1000 draw Ella's name can be expected to come about
(2×100) = 200 times.

the way I look at this is by visualizing the translations using the parent function of f(x)=|x|
the function moved up three and to the right by one which led to my conclusion
The equation that represents the function graphed on the coordinate plane is y = |x - 1| + 3.
What is function?A function is a relation between a dependent and independent variable. We can write the examples of functions as -
y = f(x) = ax + b
y = f(x, y, z) = ax + by + cz
Given is to find the equation that represents the function graphed on the coordinate plane.
The parent function for the given function is -
y = |x|
The function rule for transformation can be written as -
(x, y) : (x - 1, y + 3)
So, we can write the function after transformation as -
y = |x - 1| + 3
Therefore, the equation that represents the function graphed on the coordinate plane is y = |x - 1| + 3.

[tex]x = 375.3[/tex]
Step-by-step explanation:
Given
See attachment for illustration
Required
Determine the horizontal distance
The horizontal distance is the distance between the technician and the base of the pole.
Represent this with x.
The relationship between x, 175ft and 25 degrees is represented as:
[tex]tan(25^{\circ}) = \frac{175}{x}[/tex] --- i.e. tan formula
Multiply both sides by x
[tex]x * tan(25^{\circ}) = \frac{175}{x} * x[/tex]
[tex]x * tan(25^{\circ}) = 175[/tex]
Make x the subject
[tex]x = \frac{175}{tan(25^{\circ})}[/tex]
[tex]x = \frac{175}{0.4663}[/tex]
[tex]x = 375.294874544[/tex]
[tex]x = 375.3[/tex] --- approximated
The distance is approximately 375.3ft
