Two students created models of the same building. One student used a scale factor of 3 centimeters (cm) = 15 meters (m). The second student used a scale factor of 4.5 = 15 m. The height of the original building is 20 meters. What is the difference between the heights of the two students' models?
Answer:
2 cm
Step-by-step explanation:
First student:
Scale factor = 3 cm to 15 m
Height of original building = 20 m
Height of the first student's model = [tex] \frac{20*3}{15} = \frac{60}{15} = 4 cm [/tex]
Second student:
Scale factor = 4.5 cm to 15 m
Height of original building = 20 m
Height of the first student's model = [tex] \frac{20*4.5}{15} = \frac{90}{15} = 6 cm [/tex]
Difference between the heights of the two students' models = 6 cm - 4 cm = 2cm
Convert 340 centimeters into inches. Round your answer to the nearest whole number.
On unit conversion the value of 340 cm is 134 inches.
What is unit conversion?
Unit conversion is a multi-step procedure that involves adding, subtracting, multiplying, or dividing by a conversion factor. Additionally, rounding and choosing the appropriate number of significant digits may be necessary during the process.
There are 2.54 centimeters in one inch.
Perform unit conversion to convert cm to inch.
To convert 340 centimeters into inches, divide 340 by 2.54 -
340 cm ÷ 2.54 cm/inch
340 / 2.54
≈ 133.8583 inches
Rounding to the nearest whole number, it is obtained -
134 inches
Therefore, 340 centimeters is approximately equal to 134 inches when rounded to the nearest whole number.

What is angle Sum Property?According to the triangle's "angle sum property," a triangle's angles add up to 180 degrees. Three sides and three angles, one at each vertex, make up a triangle. The sum of the interior angles in a triangle is always 180, regardless of whether it is acute, obtuse, or right.
Given:
As, the two sides of Triangles are and angles opposite to equal sides are also equal.
So, the measure of two angles are x.
Now, using Angle Sum Property
x+ x + 40= 180
2x + 40= 180
2x = 140
x= 70
Hence, the value of x is 70.

The system of equations graphed below has how many solutions?
A. Infinitely many
B. 2
C. 1 D. 0
========================================================
Explanation:
Each given equation is in the form y = mx+b, with m as the slope
The slope of each equation is m = -3/2
Since the lines have the same slope, but different y intercepts, we have two parallel lines.
Parallel lines never intersect, so we don't have any solutions.
A solution to a system is an (x,y) point that is on both lines at the same time, making both equations true simultaneously.
A system with no solutions is considered inconsistent.
If f(x)=-3x+4 and g(x)=2, solve for the value of x for which f(x) = g(x) is true.

Step-by-step explanation:
Let us explain how we can solve the problem with tax added
If the cost of an item is 100% and the tax added is 5%, what is the cost after taxYou should add 100% + 5% = 105%, the cost after tax is 105%To change the number from percentage form to the normal form divide it by 100In the question the given is:
∵ The fee to groom the dog is $75
∵ The tax added is 6.75%
→ Assume that the fee of groom = 100%
∴ The fee after-tax = 100% + 6.75% = 106.75%
→ To find the fee after-tax multiply the fee before the tax by
the percentage fee after-tax, remember to change the percentage
to a normal number
∴ The fee after-tax = 75 × 106.75%
∴ The fee after-tax = 75 × (106.75/100)
∴ The fee after-tax = $80.0625
∵ He has $80
∵ $80.0625 > $80
∴ That means he has not enough money to pay for the service
∴ $80 is not enough to pay for the service
2x2+2=402 prime factorization
9514 1404 393
Answer:
as written: 2(x² +1) = 2·3·67as standard-form quadratic: 2(x² -200) = 0Step-by-step explanation:
A prime factorization of a polynomial is one in which each factor cannot be factored further using integers. Here, we can remove a factor of 2 from each side to get ...
2(x² +1) = 2(201)
The constant 201 can be further factored to primes:
2(x² +1) = (2)(3)(67)
__
If the equation is written in standard form:
2x² -400 = 0
again, a factor of 2 can be removed:
2(x² -200) = 0
If the binomial constant were a perfect square, this could be factored further. It is not, so it can't.

what number do you need to multiply by 100 to get the same result as 16.2 divided by 10 explain
Answer:
You would need to multiply 100 by 0.0162. 100 x 0.0162. Thus the answer is 0.0162
Step-by-step explanation:
By dividing 16.2 by 10 you get the answer 1.62. 1.62 is 1.62% of 100 which in decimal form is 0.0162. This gives you the number you need to multiply by 100 to get the same number as you would dividing 16.2 by 10.

Some information about the surface area and volume of two similar solids has been given fill in the missing value.
Answer:
1216 yd³Step-by-step explanation:
GivenSolid 1 | Solid 2Surface area = 1100 yd² | Surface area = 176 yd²Volume = 19000 yd³ | Volume = xSolids are similarLet the scale factor be k, then
Surface area is a product of 2 dimensions so the ratio of surface area of the solids would be k²Volume is the product of 3 dimensions so the ratio of volumes would be k³Considering this we have:
1100 = 176*k²19000 = x*k³The value of x is
x = 19000/k³Finding the scale factor
k= √1100/176 = 2.5So the answer is
x = 19000/2.5³ = 1216 yd³Multiply and simplify 8 times 3/10
