14/y=112/72,what is y someone pls help

Answer:

rise

Step-by-step explanation:

The y-values of equivalent ratios increase at the same rate as their x-values. The vertical distance between points is constant, and the horizontal distance between points is constant. This forms a straight line.

Explanation:

Equivalent proportions (which are, as a result, equal parts) are two proportions that express a similar connection between numbers. We can make comparable proportions by duplicating or separating both the numerator and denominator of a given proportion by a similar number.

Two ratios that have the same value are called equivalent ratios. To find an equivalent ratio, multiply or divide both quantities by the same number. It is the same process as finding equivalent fractions.

Answer:

The y-values of equivalent ratios increase at the same rate as their x-values. The vertical distance between points is constant, and the horizontal distance between points is constant. This forms a straight line.

Answer:

[tex]x=5,y=10[/tex]

Step-by-step explanation:

Given:

                      [tex]4x - 2y = 0[/tex]        equation:1

                 [tex]-x - 2y = -25[/tex]        equation:2

Terminating the equations by subtracting equation:2 from equation:1

                     [tex]4x - 2y -(-x - 2y)= 0-( -25)\\\\ 4x-2y+x+2y=25\\\\5x=25\\\\x=5[/tex]

Putting 'x' in equation :1

                                [tex]4(5) - 2y = 0\\\\20-2y=0\\\\2y=20\\\\y=10[/tex]

[tex]x=5,y=10[/tex]

The value of h(t) when [tex]t=\frac{15}{32}[/tex] is 10.02.

Solution:

Given function [tex]h(t)=-16t^2+15t+6.5[/tex]

To find the value of h(t) when [tex]t=\frac{15}{32}[/tex]:

[tex]h(t)=-16t^2+15t+6.5[/tex]

Substitute [tex]t=\frac{15}{32}[/tex] in the given function.

[tex]$h\left(\frac{15}{32} \right)=-16\left(\frac{15}{32} \right)^2+15\left(\frac{15}{32} \right)+6.5[/tex]

            [tex]$=-16\left(\frac{225}{1024} \right)+15\left(\frac{15}{32} \right)+6.5[/tex]

Now multiply the common terms into inside the bracket.

           [tex]$=-\left(\frac{3600}{1024} \right)+\left(\frac{225}{32} \right)+6.5[/tex]

Now, in the first term, the numerator and denominator both have common factor 16. So reduce the first term into the lowest term.

          [tex]$=-\left(\frac{225}{64} \right)+\left(\frac{225}{32} \right)+6.5[/tex]

To make the denominator same, take LCM of the denominators.

LCM of 64 and 32 = 64

        [tex]$=-\left(\frac{225}{64} \right)+\left(\frac{225\times2}{32\times2} \right)+6.5\times\frac{64}{64}[/tex]

        [tex]$=-\frac{225}{64} +\frac{450}{64}+\frac{416}{64}[/tex]

        [tex]$=\frac{-225+450+416}{64}[/tex]

       [tex]$=\frac{641}{64}[/tex]

       = 10.02

[tex]$h\left(\frac{15}{32} \right)=10.02[/tex]

Hence the value of h(t) when [tex]t=\frac{15}{32}[/tex] is 10.02.

Answer:

375 meters

Step-by-step explanation:

We use the tangent ratio to determine the height of the height of the cliff.

We have that, the boat is 600 meters from the base of a cliff.

We also know that, the angle of elevation to the top of the cliff is 32°

Using the tangent ratio, we have:

[tex] \tan(32) = \frac{h}{600} [/tex]

We solve for h to obtain:

[tex]600\tan(32) = h[/tex]

[tex]h = 374.92[/tex]

Therefore the height of the cliff is approximately 375 meters

The angle of elevation is an angle that is formed between the horizontal line and the line of sight, hence the Height of the cliff is

374.4 meters

Given Data

Opposite/Height of cliff = ??

Adjacent/Distance of boat from base = 600 meters

Angle of elevation ∅  = 32°

By applying SOH CAT TOA

Tan  ∅ = Opp/Adj

Substituting our given Data we have

Tan 32 = Opp/600

0.624 = Opp/600

Cross multiply we have

Opp = 0.624*600

Opp = 374.4 meters

Step-by-step explanation:

Some of the properties of a trapezium include:

- A pair of opposite parallel sides (the long and short base)

- Has 4 sides (meaning it is a quadrilateral)

-

The functions whose graphs include the point (16, 4) is y = x−12.

Option: D.

Step-by-step explanation:

To find the function that passes through the point (16,4).

Substitute the point in all the equations and equate the final values to find the correct equation.

A. y=2x.

Substitute (16,4).

4=2(16).

4≠32.

Thus the equation doesn't contains the point (16,4).

B. y=[tex]x^2[/tex].

Substitute (16,4).

4=[tex]16^2[/tex].

4≠ 256.

Thus the equation doesn't contains the point (16,4)

4=16+12.

4≠28.

Thus the equation doesn't contains the point (16,4)

D. y=x−12.

4=16-12.

4=4.

Thus the equation contains the point (16,4)

E. y=14x.

4=14(16).

4≠224.

Thus the equation doesn't contains the point (16,4)

∴The functions whose graphs include the point (16, 4) is y = x−12.

Answer:

19

Step-by-step explanation:

We have that out of 100 products , 93 are ready for purchase by customers.

The probability of the product being purchased is 93% or 0.93.

The expectation is given by;

E(x)=n*p(x)

If the 20 products are selected, then we have n=20

The expectation is

[tex] \bar x = 0.93 \times 20[/tex]

[tex] \bar x = 18.6[/tex]

Thus approximately 19 customers will be ready to purchase

Final answer:

The expected mean number of products ready for purchase out of 20 selected is 18.6, calculated by multiplying the probability of one product being ready (0.93) by the total number of products (20).

Explanation:

To determine the expected mean number of products ready to purchase out of a selection of 20 products, given that out of each 100, 93 are ready, we use the concept of probability and expected value. The probability that any one product is ready to purchase can be represented as 93/100 or 0.93.

For the expected mean number of products ready to purchase out of 20, we multiply the probability that one product is ready (0.93) by the total number of products chosen (20):

Expected mean number = 0.93 * 20 = 18.6

Therefore, we would expect that, on average, 18.6 out of 20 products selected would be ready to purchase.

Answer:

Length = 22 inches, Width = 5 inches

Step-by-step explanation:

Let P represent the Perimeter, L , the length and W, the width

Perimeter of a rectangle, P = 2 (L + W) ....eq 1

from the question;

L = 2 + 4W .....eq 2

Slotting in the respective values of P and L in eq 1

54 = 2{(2 + 4W) + W}

Expanding the bracket

54 = 2(2 + 5W)

54 = 4 + 10W

Subtracting 4 from both sides of the equation

54 - 4 = 10 W

50 = 10W

Dividing both sides by the coefficient of W which is 10

5 = W

Therefore, W = 5 inches

Slotting in the value of W in eq 2

L = 2 + 4(5)

L = 2 + 20

L = 22 inches

Now lets check our answers by slotting in the values of P, L and W in eq 1

54 = 2 (22 + 5)

54 = 2 (27)

54 = 54

Since both sides of the equation are equal, the values of L and W are correct

Hence Length = 22 inches, Width = 5 inches

Final answer:

It will take Shaun 156 hours to mow 78 lawns based on his current rate of mowing 3 lawns in 6 hours.

Explanation:

To determine how many hours it will take Shaun to mow 78 lawns based on the rate at which he mows 3 lawns in 6 hours, we will use a proportion. First, we find the rate at which Shaun mows lawns per hour, which is 3 lawns / 6 hours = 0.5 lawns per hour. Next, we set up a proportion where the total number of lawns he needs to mow (78 lawns) is set equal to the product of the number of hours it takes (which we are trying to find) and the rate at which he mows lawns (0.5 lawns per hour).

So, the proportion is:
78 lawns = x hours ( 0.5 lawns/hour.)

Dividing both sides of the equation by 0.5 lawns/hour gives us:

x hours = 78 lawns / 0.5 lawns/hour

x hours = 156 hours.

Therefore, it will take Shaun 156 hours to mow 78 lawns at his current rate.

Answer:

The solution is -5 or 11

Step-by-step explanation:

We are given the equation;

[tex]4(3-x)^\frac{4}{3}-5=59[/tex]

We are supposed to solve the equation;

Taking 5 to the other side;

[tex]4(3-x)^\frac{4}{3}=59+5[/tex]

[tex]4(3-x)^\frac{4}{3}=64[/tex]

Dividing both sides by 4

[tex](3-x)^\frac{4}{3}=\frac{64}{4}[/tex]

[tex](3-x)^\frac{4}{3}=16[/tex]

We can cube both sides;

[tex]((3-x)^\frac{4}{3})^3=16^3[/tex]

[tex](3-x)^4=4096[/tex]

Then we can get the fourth root on both sides of the equation;

[tex]\sqrt[4]{ (3-x)^4} =\sqrt[4]{4096}[/tex]

We get;

[tex]3-x=+8 or -8[/tex]

Solving for x

[tex]3-x=8 and 3-x=-8[/tex]

Therefore;

[tex]x=-5 or 11[/tex]

Therefore, the solution is -5 or 11

Answer:

-27 and -18

Step-by-step explanation:

Solve algebraically. Use a variable and an expression to represent the numbers.

let the smaller number be "x"

The bigger number is x + 9.

The two numbers are "x" and "x + 9".

The sum of two numbers means when you add them together. If their number is −45, then:

x + x + 9 = −45

Simplify and isolate "x" to solve in the equation.

x + x + 9 = −45        Collect like terms (numbers that have "x") to simplify

2x + 9 = −45        Isolate "x"

2x + 9 - 9 = −45 - 9        Subtract 9 from both sides

2x = −54

2x/2 = −54/2        Divide both sides by 2

x = -27       Value of smaller number

The bigger number is x + 9. Substitute "x" for -27 and solve.

x + 9

= -27 + 9        Add together

= -18        Value of bigger number

Therefore the two numbers are -27 and -18.

Answer:

if -45 + -9 = -54 that means - 54 + 9 = -45
