If the product of two positive integers is 180 and the larger number is 5 times the smaller number, what are the numbers

1 answer:

7 0

Let the smaller number be x
The bigger number is 5x

5x(x) = 180
5x² = 180
x² = 180÷5
x²=36
x=√36
x = 6

x=6
5x = 6 x 5
5x = 30

So the two numbers are 6 and 30

V : 33= 7 : 11 what is the answer to this please

UkoKoshka [18]

The value of V illustrated in the ratio V : 33= 7 : 11 is 21.

<h3>What is a ratio?</h3>

It should be noted that a ratio is simply used to show the relationship between the variables and illustrate the comparison.

In this case, the value of V can be illustrated as:.

V/33 = 7/11

Cross multiply

11V = 33 × 7

V = (33 × 7) / 11

V = 21

Therefore, V is 21.

The circumference of the equator of a sphere was measured to be 82 82 cm with a possible error of 0.5 0.5 cm. Use linear approxi

True [87]

Answer:

The maximum error in the calculated surface area is approximately 8.3083 square centimeters.

Step-by-step explanation:

The circumference ( $s$ ), in centimeters, and the surface area ( $A_{s}$ ), in square centimeters, of a sphere are represented by following formulas:

$A_{s} = 4\pi\cdot r^{2}$ (1)

$s = 2\pi\cdot r$ (2)

Where $r$ is the radius of the sphere, in centimeters.

By applying (2) in (1), we derive this expression:

$A_{s} = 4\pi\cdot \left(\frac{s}{2\pi} \right)^{2}$

$A_{s} = \frac{s^{2}}{\pi^{2}}$ (3)

By definition of Total Differential, which is equivalent to definition of Linear Approximation in this case, we determine an expression for the maximum error in the calculated surface area ( $\Delta A_{s}$ ), in square centimeters:
