Answer:

Yes, they are equivalent, because one is just a reduced version of the other. Since they are equally balanced when reduced, they are equivalent ratios.

Answer:

Yes, It is equivalent.

Step-by-step explanation:

To convert [tex]\frac{10}{16}[/tex] , so the denominator is 16, multiply the numerator and denominator by 1.

[tex]\frac{5*2}{8*2}[/tex] vs [tex]\frac{10*1}{16*1}[/tex]

Now we have two fractions with the same denominator, so we can easily compare the numerators to determine if they are equal;

[tex]\frac{10}{16}[/tex] vs [tex]\frac{10}{16}[/tex]

As you can see, the numerators colored in black above are the same. Therefore, the answer to "Is 5/8 equal to 10/16?" is yes!

The actual weight of the animal is between 450.2 and 426.2 pounds

An equation is an expression that shows the relationship between two or more numbers and variables.

Inequality can be used to show that two variables or numbers are not equal to each other.

The weight of the larger animals can be off by 12 pounds. Let x represent the actual weight of the animal. If the scale reads 438.2 lbs, hence:

|x - 438.2| = 12

x - 438.2 = 12; or -(x - 438.2) = 12

x = 450.2; or x = 426.2

The actual weight of the animal is between 450.2 and 426.2 pounds

Answer:

Step-by-step explanation:

So we are not counting each line segment forming a cube. We are actually counting the four sides of the overall shape, and the number of segments inside it.

It will increase by 2 each time.

So if we start at 4(the four outside lines), go to 6(adding 2 on the inside), then to 8(adding 2 more on the inside), we continue this 100 times, correct?

So our equation would be

(x times 2) +4  (if we start at the SECOND term and count that as the first )

so, to figure out the answer to out problem, we insert 100 for x

(100 x 2)+4 = 204

This would leave us with one big square (4 outside line segments) With 100 segments going horizontal, and 100 vertical)

The line which is perpendicular to the given line y = -x/8 + 3 is y - 8x =-2, there slopes are negative reciprocals of each other

Given data

line y = -x/8 + 3

The equation of a line is represented as y = mx + c where m represents the slope. The unique feature of perpendicular line is that the slopes are negative reciprocals of each other.

Hence we find the line that has same value of m which is the slope

using the second option: y - 8x = -2

y - 8x = 2

y = 8x - 2

Answer:

7x+y=3 is not a linear equation.

The cost equation for Debra is given by 4x + 6y = 94 and for Heather is 5x + 3y = 77.

Linear equations in two variable have one, none, or infinitely many solutions, with the highest exponent order of 1 in each of the two variables. The standard form of a two-variable linear equation is ax + by + c = 0, where x and y are variables. Solutions can also be written in pairs, for example (x, y). A two-variable linear equation system is represented graphically by two straight lines that can intersect, parallelize, or coincide.

According to the given condition, we have 2 equations:

4x + 6y = 94
5x + 3y = 77

Now, multiply by 2 on both sides of the equation 5x + 3y = 77 to obtain:

10x + 6y = 154

Now, subtracting the equation 10x + 6y = 154 and 4x + 6y = 94.

[10x + 6y = 154] - [ 4x + 6y = 94]

6x + 0y = 60

x = 10

Putting the value of x = 10 in equation 4x + 6y = 94, we get

y = 9

So, the cost of 1 hammer is 10$ and tape is 9$.

According to the image  the x-axis, there is a reflection (- 4, 2 ).

An image that has been flipped has no points that are closer to the mirror line than the original shape. The point's coordinate must be multiplied by -1 in order to reflect it over the axis. Simply add -1 to the coordinate of the point to reflect it over the axis.

Analytic geometry, often known as coordinate geometry, is the study of geometry using coordinate points. It is possible to determine distances between points using coordinate geometry, as well as divide lines into m:n segments, locate a line's midpoint, determine the area of a triangle in the Cartesian plane, and perform other operations.

[5.999, 6]. 191.984

[5.99, 6]. 191.84

The instantaneous velocity at t = 6 is v(6) = 192 ft/s

The distance traveled as a function of time is s(t) = 16•t² ft.

(a) The distance traveled during the time interval [6, 6.5] is found as follows;

s(6) = 16 × 6² = 576

s(6.5) = 16 × 6.5² = 676

The distance traveled in the interval, [6, 6.5], ∆s(t) = 676 - 576 = 100

The distance traveled during the time interval [6, 6.5] = 100 feet

(b) Average velocity = ∆s(t)/∆t

∆t = 6.5 - 6 = 0.5

Therefore;

∆s(t)/∆t = 100/0.5 = 200

The average velocity = 200 ft./s

(c) The average velocities over the given time intervals, obtained using a graphing calculator, are;

Given that at t = 6, as the time interval approaches zero from the right and from the left, the average velocity approaches 192 ft./s, the instantaneous velocity at t = 6, v(6) is 192 ft./s

v(6) = 192 ft./s

Using calculus, differentiation, we have;

v(t) = ds/dt = 2×16 × t = 32•t

v(6) = 32 × 6 = 192

Probability is the study of chance . The part of mathematics known as probability deals with fractional representations of the likelihood that an event will occur or that a statement is true. An event's probability is a number between 0 and 1, where, 0 denotes the event's impossibility and 1 denotes certainty.

Probability is calculated by the fraction possible outcomes ÷ total outcomes

a) The first spinner has the total 4 sections. so there are 4 total outcomes.

Favorable outcome = 1

Total number of favorable outcome=2

Probability P(1|A) = favorable outcome ÷ total outcome

∴ P(1|A) =2/4 or P(1|A) =1/2

b) The first spinner has the total 4 sections. so there are 4 total outcomes.

Favorable outcome = 1

Total number of favorable outcome=3

Probability P(1|B) = favorable outcome ÷ total outcome

The average rate of change of f(x) = x - 2√x on the interval [1, 9] is 1/2.

It is a measure of how much the function changed per unit, on average, over that interval.

We have,

f(x) = x - 2√x

On the interval [1,9].

[1, 9] = [a, b]

The average rate of change:

= f(b) - f(a) / b - a

= f(9) - f(1) / 9 - 1

= [(9 - 2√9) - (1 - 2√1)] / 8

= [ (9 - 6) - (1 - 2) ] / 8

= (3 + 1) / 8

= 4 / 8
