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

Answer:
Angle DGF = DEF
Step-by-step explanation:
Since all the angles are congruent in the diagram and the hypothenuses are both congruent, it makes the other triangle, DEF congruent to DGF.
In other words, sense all 3 angles are congruent and they share a side, DEF is congruent to DGF.

What is the value of x?
40
70
140
160
Answer: 70
Answer: the answer is 70
Step-by-step explanation:
The value of x is 70.
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.

What is standard form of a number ?Standard form of a number is used to write very large or very small numbers in compact way or all numbers in a particular way that their numerical part is any decimal between 1 to 10
Standard form of a number is a × bⁿ, where a is coefficient or number part and bⁿ is × 10⁰ , where b, base is 10 and n is any integer power of 10. The number part a must be a number between 1 to 10.
Given number is:
Seven and twelve hundredths 7.12
7.12 = 7.12 × 10⁰ is the standard form of 7.12 as numerical part 7.12 is a decimal number between 1 to 10

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

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.

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

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.

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.
What is the equation of the line that is parallel to y=3x+8 and passes through the point (-3,4)
Answer:
The parallel equation would be: y=3x+13
