It's 26 because the pattern is adding 5. To find the pattern, just subtract the numbers from the ones before so 11-6 and 21- 16 which both equal 5. Then just add 5 to the last number and you'll find it to be 26.
Answer:
351.9 cm³
Step-by-step explanation:
The ratio of the areas of two similar solids is equal to the square of the ratio of the lengths.
A₂ / A₁ = (s₂ / s₁)²
The ratio of the volumes of two similar solids is equal to the cube of the ratio of the lengths.
V₂ / V₁ = (s₂ / s₁)³
Therefore, we can say:
V₂ / V₁ = (A₂ / A₁)^(3/2)
Plugging in values:
V / 8 cm³ = (324 cm² / 26 cm²)^(3/2)
V = 351.9 cm³
Answer:
The value of x is -29 and the value of y is -26
Step-by-step explanation:
we know that
If two figures are congruent, then its corresponding angles and its corresponding sides are congruent
so
The length of the corresponding sides must be equal
----> equation A
----> equation B
Note
The length of one side of the triangle equal to -5 is not logical, however we will continue with the resolution of the problem for didactic purposes.
Solve the system by graphing
Remember that
the solution of the system of equations by graphing is the intersection point both graphs
using a graphing tool
The solution is the point (-29,-26)
see the attached figure
therefore
The value of x is -29 and the value of y is -26
<span>Equation (1) x + y = 200
Eauation (2) x = y - 40
x represents the distance from the original location to the firstt city
y represents the
distance from the first city to the second city.
Solution:
(1) x + y = 200
(2) x - y = - 40
----------------------
2x = 200 - 40
2x = 160
x = 160 / 2
x = 80
x + y = 200 => y = 200 - x = 200 - 80 = 120
Therefore the solution (x,y) is (80,120)
Answer: the pair of coordinates that represents the solution (in miles) to this system of
equations is (80, 120) </span>
Answer:
use the formula SA = 6(a + h), where s = side length of the base, a = apothem length, and h = height of the prism.
