if we look on one side, we already have one measurement. 4 cm. ok, that's the measurement on that side. look to the left now. that other side is also the same length, so we take that number and multiply it be 2 to get
[tex]4 \times 2[/tex]
Wait! we're not done yet. look at the top. do you see the 3? well that's the width for the top of the rectangle. the bottom must be the same to right? so we get
[tex]3 \times 2[/tex]
add both equations and you get
[tex](4 \times 2) + (3 \times 2)[/tex]
The answer is 14cm! Don't forget to label. ;)

If the sale tax rate is 8.75% in New York State, how much sales tax would you pay for a $35 pair of pants? And at Best Buy they have a 50" TV tagged as $1250. It's on sale for 15% and sale tax is 8%. What is the final cost?
Answers
The pants are $38.06 and the television is $1,147.50.
The sales tax on the pair of pants is calculated by multiplying $35 x .0875 = $3.06
The total cost is $35 + 3.06 = $38.06.
The sales price of the television is calculated by multiplying $1,250 x .85, (100 - .15 discount = .85) = $1,062.50 is the sales price
The sales tax is calculated by multiplying $1,062.50 x .08 = $85
The total price is $85 + $1,062.50 = $1,147.50

What is the range and domain of a function?A function's range is the set of all values that the function accepts, and its domain is the set of all values for which the function is defined.
The domain is for the independent variable while the range is for the dependent variable.
Given the profit function,
p(x)=20x-75
The graph of this function has been shown below which is representing the domain as (∞,∞) but in the our profit function x is the number of lawns that mowing so it will be a whole number and positive number.
Since domain is the set of all x's value thus it will be domain of the function.

A tug boat traveled -15 miles in 0.3 hours what was its velocity
Answers
Answer:
22.35 m/s
Step-by-step explanation:
The distance is always a positive unit, so distance traveled (d) = 15 miles
Time (t) = 0.3 hours
Time (t) = 0.3 * 60 = 18 minutes
(1 hour = 60 minutes)
Velocity (v) = ?
The formula of distance is: d = v*t
=> v = d/t = 15/18 = 0.83 miles/minute
we can also calculate velocity is meter/sec, for that
1 minute = 60 sec
=> 18 mins = 18*60 = 1080 sec
1 mile = 1609.34 meters
=> 15 miles = 15 * 1609.34 = 24,140 m
hence,
v = 24,140/1080 = 22.35 m/s

Describe the transformations that will map triangle A to triangle B and illustrate the similarity between the two triangles. A) rotate 90° clockwise and then translate 6 units down B) translate 4 units down and rotate 180° about the origin C) reflect the triangle across the y-axis and translate 4 units down D) reflect triangle A across the x-axis and then translate 1 unit right
Answers
B) Translate 4 units down and rotate 180°
Rule for 180° = (x, y) ---- (-x, -y)
Pick one point on Triangle A. (I picked the pointiest point)
(-5, 6)
Now translate 4 units down.
You will now be on (-5, 2)
Rotate 180°
You will now have (5, -2)
And the pointiest point on Triangle B is (5, -2)
So, B is the correct answer.
Option B is correct. The required transformation that will map triangle A to triangle B and illustrate the similarity between the two triangles is translating 4 units down and rotate 180° about the origin
In order to determine the transformation that will map triangle A to B, we need to do the following:
Select any of the coordinates of the verticesUsing the coordinate point (-5, 6) on triangle AIf a coordinate (x, y) is rotated 180° about the origin, the resulting coordinate will be at (-x, -y)For the coordinate (-5, 6), rotated 180° about the origin, the resulting coordinate will be at (5, -6)If the coordinate is translated 4 units down as seen from the figure, the resulting coordinate of the vertex on triangle B will be at (5, -6+4) i.e. (5, -2)
We can see that it tallies with a similar coordinate on triangle B. Hence the required transformation that will map triangle A to triangle B and illustrate the similarity between the two triangles is translating 4 units down and rotate 180° about the origin

In a 30-60-90 triangle, the length of the long leg is 8. Find the length of the hypotenuse.
Answers
Answer:
Step-by-step explanation:
In a 30-60-90 triangle, the ratio of the lengths of the angles' opposite sides are 1-√3-2.
If the long leg is 8, then the short one is 8/√3, or 8√3/3.
Therefore, the hypotenuse, which is double the short leg, is 16√3/3.
In a 30-60-90 triangle, the long leg is √3 times the short leg and the hypotenuse is twice the short leg. By knowing the long leg and using these relationships, we can work out the short leg and then the hypotenuse. In this specific problem, the hypotenuse of the triangle is approximately 9.24.
Explanation:
In a 30-60-90 triangle, the ratio of the side lengths is consistent. The length of the long leg is always √3 times the length of the short leg. The hypotenuse, which is the longest side of the triangle, is always twice the length of the short leg. If the length of the long leg is 8, the formula of this triangle can be used to find the length of the hypotenuse.
However, in your question, the length of the short leg isn't given. But based on the formulas for a 30-60-90 triangle, we can work it out. As long as we know that the long leg is √3 times the short leg, we can solve for the short leg, hence it's 8/√3.
Then, as the hypotenuse is twice the short leg, so hypotenuse = 2 * (8/√3) = 16/√3 ≈ 9.24.

Which is the best estimate for the average rate of change for the quadratic function graph on the interval 0 ≤ x ≤ 4?
A) −1
B) −2
C) −3
D) −4
Answers
A) -1
EXPLANATION
The average rate of change of the given quadratic function on the interval 0 ≤ x ≤4 is the slope of the secant line connecting the points (0,f(0)) and (4,f(4)).
That is the average rate of change is:
[tex] = \frac{f(4) - f(0)}{4 - 0} [/tex]
From the graph, f(0) is 0 and f(4) is -4.
We plug in these values to obtain;
[tex] = \frac{ - 4 - 0}{4 - 0} [/tex]
This simplifies to;
[tex] = \frac{ - 4}{4} [/tex]
[tex] = - 1[/tex]

Answer:
None of the above
Step-by-step explanation:
10 + 10 + 4 + 4 = 28
First choice
4 + 4 + 5 + 5 = 18 X
Second choice
8 + 8 + 3 + 3 = 22 X
Third choice
9 + 9 + 7 + 7 = 32 X
Therefore there is none that are the same.
Answer:
None of the above.
Step-by-step explanation:
A rectangle has one side that measures = 10 units
the another side that measures = 4 units
Perimeter = 2( Length + width )
Perimeter of this rectangle = 2( 10 + 4 )
= 2(14) = 28 units
We have to find the same measurement units that shows the same perimeter.
1. 4 units 5 units
Perimeter = 2( 4 + 5 ) = 2 × 9 = 18 units
2. 8 units 3 units
Perimeter = 2( 8 + 3 ) = 2 × 11 = 22 units
3. 9 units 7 units
Perimeter = 2( 9 + 7 ) = 2 × 16 = 32 units
There are no another rectangle with the same perimeter.

If the interest earned is $25 and the principal is $500 and the interest rate is 5%, what is the time?
Formula = simple interest= principal times annual interest rate times the time in years
Answers
To find out how long it takes to earn $25 in interest on a principal of $500 at a 5% annual interest rate, use the simple interest formula. The calculation reveals it takes 1 year.
Explanation:The question asks us to determine the time it takes to earn $25 in interest on a principal of $500 at an annual interest rate of 5% using simple interest. The formula for simple interest is Interest = Principal × Rate × Time. We can rearrange this formula to solve for time (Time = Interest / (Principal × Rate)).
Given that the interest earned is $25, the principal is $500, and the rate is 5% (0.05 in decimal form), we substitute these values into our rearranged formula to find the time.
Interest = $25Principal = $500Rate = 5% or 0.05Substituting these into the formula gives us:
Time = $25 / ($500 × 0.05) = $25 / $25 = 1 year
Therefore, it takes 1 year to earn $25 in interest at a 5% annual rate on a $500 principal using simple interest.

The value of 9 2/3-4 1/5 number is 5 7/15 .
To find the value of 9 2/3 - 4 1/5, we first need to convert each mixed number into an improper fraction. For 9 2/3, the improper fraction is (9 × 3 + 2)/3 = 29/3. For 4 1/5, the improper fraction is (4 × 5 + 1)/5 = 21/5.
Next, we need to find a common denominator to subtract these fractions. The least common multiple of 3 and 5 is 15, so we convert each fraction to have this common denominator. The first fraction becomes (29/3) × (5/5) = 145/15, and the second fraction becomes (21/5) × (3/3) = 63/15.
Now we can subtract the second fraction from the first: 145/15 - 63/15 = (145 - 63)/15 = 82/15. To convert this back into a mixed number, we divide 82 by 15 to get 5 with a remainder of 7, so the mixed number is 5 7/15.
Therefore, the answer is 5 7/15.
