The value of the digit 2 in the number 42,780 is 10 times the value of the digit 2 in which number?

Answer:10

Step-by-step explanation:

Answer:

10

Step-by-step explanation:

8 + (9- 1) ÷ 4

Use PEMDAS to determine order of operations in a mathematical expression

The order of operations is

P = parentheses
E = exponent

M = multiplication

D == division

A = addition

S = subtraction

Note that multiplication and division have the same priority and we go from left to right that case. Because it does not affect the answer.

So 12 ÷ 4 x 6 = 12 x 6 ÷ 4
Same for addition and subtraction - same priority

Using PEMDAS

(9 - 1) is executed first giving 8

The expression becomes 8 + 8 ÷ 4

Next division is performed so 8 ÷ 4 is executed giving 2 as the answer

Finally 8 + 2 is executed giving 10

Answer:

x = -2

Step-by-step explanation:

The equation is,

→ 17 + x = 15

Now the value of x will be,

→ 17 + x = 15

→ x = 15 - 17

→ [ x = -2 ]

Hence, the value of x is -2.

Step-by-step explanation:

17+x=15

17+x-17=15-17

x=-2

Answer:

Greater number = 58

Step-by-step explanation:

The equation is,

→ (x + 19) + x = 97

Now the value of x will be,

→ (x + 19) + x = 97

→ 2x = 97 - 19

→ x = 78/2

→ [ x = 39 ]

Then the greater number is,

→ x + 19

→ 39 + 19 = 58

Hence, the answer is 58.

Answer:

58

Step-by-step explanation:

first number=x

second number= x+19

x+x+19= 97

thus, the two numbers are 39 and

The slope of a line is y=mx+c, where m is the slope. The lines is perpendicular to y = 1/4x -3 is Y=-4x+6.

The slope of a line is y=mx+c, where m is the slope.

The given line is y = 1/4x -3.

slope m1=1/4.

slope of second line=-(1/m)

=-(1/1/4)

=-4

point slope intercept form is y-y1=m(x-x1)

Equation of the perpendicular line passing through point (0,6) is

y-6=-4(x)

y=-4x+6

Therefore the line perpendicular to y = 1/4x -3 is Y=-4x+6.

well, we know the rate is compounding at 800% per minute.

the elapsed time will be 12 seconds, and since a minute has 60 seconds, that'd be 12/60 minutes.

the compounding period is 3 seconds, and since a minute has 60 seconds, that means is compounds 60/3 times, or namely 20 times.

When Abby stacked two cube-shaped blocks, the surface area of the figure if s = 5 inches is 250 inches²

It should be noted that the surface area of a solid object is a measure of the total area that the surface of the object occupies.

Length (l) = 5 in

Width (w) = 5 in

Height (h) = 10 in

Surface area of figure

If a string has 20 light bulbs and these lights are all wired in series, so that if one light bulb fails, the whole string fails and the probability that any one light fails is 0.2 and each of the individual lights are independent of each other, then the probability that the string will not fail is 0.0115.

Probability in mathematics deals with the likelihood of an event to take place.

The probability that the string will not fail refers to when all 20 bulbs will not fail. As given in the conditions, each of the individual lights are independent of the other. Therefore;

the probability that any one of the lights will not fail is:

1 - probability that any one light fails = 1 - 0.2 = 0.8

And we need all 20 to be complete. The unity of events is a product of probabilities. Therefore the probability that the string will not fail is:

P = 0.8^20

P = 0.0115

Hence 0.0115 is the probability that the string will not fail.

The angles 35° 65° and 28° are acute angles and the angle 91° is an obtuse angle

The angle measures are given as:

35° 91° 65° 28°

As a general rule:

Angles that are less than 90 degrees are acute angles

This means that

The angles 35° 65° and 28° are acute angles

Also, we have

Angles that are between 90 degrees and 180 degrees are obtuse angles

This means that

The angle 91° is an obtuse angle

At an altitude of 500 meters, the atmospheric pressure (p) will be 61.46 pascals.

The exponential constant, denoted by the symbol e, is an essential mathematical constant. Its value is approximately equal to 2.718. This value occurs very frequently in mathematics when it is used to model physical and economic phenomena.

Here, we are given an exponential function- p = 101.3[tex]e^{-0.001h}[/tex]

where p = atmospheric pressure in pascals

h = altitude in meters.

If the altitude is 500m

h = 500

Then,

p = 101.3 [tex]e^{-0.001 * 500}[/tex]p

=  101.3 [tex]e^{-0.5}[/tex]p

=  101.3/ [tex]e^{-0.5}[/tex]p

= 101.3/ 1.648p

= 61.46

Thus, at an altitude of 500 meters, the atmospheric pressure (p) will be 61.46 pascals.

Answer:

A(4, 4), B(1, 2), C(-3, 1)

Step-by-step explanation:

Because the triangle is rotated 180° about the origin you are just rotating it 2 quadrants, the size stays the same.

The rule for rotating 180° is if (x, y) is rotating 180° then the new position is (-x, -y).

So:

A(-4, -4), which then becomes B(-(-4), -(-4) ) = B(4, 4)

B(–1, –2) which becomes B(-(–1), –(-2) ) = B(1, 2)

C(3, –1) which becomes C(-3, –(-1) ) = C(-3, 1)

By using the principles of translation, the following equation can be derived for the graph of the translated text:

g(x) = |x + 2| + 1.

According to operations like multiplication or sum/subtraction either in its range (including values of y) or in its domain, a translation is represented by a change in the function graph (involving values of x).

Examples include shifts to the left, right, or bottom; compression or stretching along the vertical or horizontal axis; reflections across the x or y axes; and rotations of a degree measured around the origin.

From the graph, we have that the parent function was:

Shifted left 2 units, hence x -> x + 2.

Shifted up 1 unit, hence y -> y + 1.

Hence, considering the parent function f(x) = |x|, the equation for the translated graph is given by:

g(x) = |x + 2| + 1.

After 1.842 hours the price of Stock A and Stock B will be the same using a set of linear equations.

A grouping of one or more linear equations containing the same variables is known as a system of linear equations.

For Stock A :

The initial price = $15.03

The rate of increase = $0.05

For Stock B :

The rate of decrease = $15.53

The rate of decrease per hour = $0.13

Then the price of stock A at noon will be:

$ 15.03 + $ (0.05 × 3) = $ 15.03 + $ 0.15 = $15.18

The period of time during which the stock price will remain constant:

15.18 + 0.05t = 15.53 - 0.14t

Simplifying the terms we get,

0.05t + 0.14t = 15.53 - 15.18

0.19t = 0.35

t = (0.35 ÷ 0.19) hours

t = 1.842 hours

Therefore, the stocks will be of equal price after 1.842 hours.
