Answer: [tex]\dfrac{16d^2}{25}+49e^2-\dfrac{56de}{5}[/tex]

Step-by-step explanation:

Given

The expression is

[tex](\dfrac{4d}{5}-7e)^2[/tex]

Use identity [tex](a-b)^2=a^2+b^2-2ab[/tex]

Apply identity

[tex]\Rightarrow \left( \dfrac{4d}{5}-7e\right)^2=\left( \dfrac{4d}{5}\right)^2+(7e)^2-2\times \left( \dfrac{4d}{5}\right)(7e)\\\\\Rightarrow \left( \dfrac{4d}{5}-7e\right)^2=\dfrac{16d^2}{25}+49e^2-\dfrac{56de}{5}[/tex]

Answer:

See below

Step-by-step explanation:

Let's convert the two fractions.

The two categories are now closest to -0.6 and closest to 0.8.

Closest to -0.6 or -3/5: -0.2, -4/5,

Closest to 0.8 or 4/5: 0.6, 2/5

Let the two whole numbers be 2x and 5x

The difference between 2x and 5x is 99. So,

5x-2x=99

3x=99

x=99/3

x=33

Therefore the two numbers are

5x=5*33=165

2x=2*33=66

Answer:

28:71

Step-by-step explanation:

99/7=14.14285714 (make sure to keep that in the calculator) that equals 1 part.

Therefore,

2×14.14...=28 (round up to nearest whole number)

5×14.14..=71 (round up to nearest whole number)

Answer:

40%

Percentage of students that picked a vanilla cupcake = (students that picked a vanilla cupcake / total number of students)x 100

(32 / 80) x 100 = 40%

Answer:

It's A) 1.8

Step-by-step explanation:

The typical mass or most common mass among all given options is 1.8 kg thus option (A) is correct.

A frequency table is a list of objects with the frequency of each item shown in the table.

The frequency of an occurrence or a value is the number of times it happens.

As per the given frequency plot.

The most common mass is at 1.8 kg and in between 1.4 and 1.8.

So, (1.4 + 1.8)/2 = 1.6 kg (not available in options)

Thus, 1.8 kg will be the typical mass.

Hence "The typical mass or most common mass among all given options is 1.8 kg".

#SPJ2

Answer: 135

Step-by-step explanation:

it increased by 20%

so the 162 is 120% of the first price

so if we multiply 162 by 100/120 we will get the first price

100/120=5/6 and 5/6*162 is 135

Answer:

$1,020.71

Hello! Answer: Area = 66

What i did was cut them into triangles and used formula for finding triangles

I did 3.3 x 4 = 13.2 then I divide 2 and get 6.6

Then I multiply by 10 cause thats how many triangles will make up the polygon and get 66

Hope this helps!

Answer:

1.66$ per liter

Step-by-step explanation:

Hi there! I hope you're having a good day so far. :)

So this equation is quite simple. To write it out, you get:

35/21.00=?

All you need to do is get a calculator and put that in.

Then you will get 1.66666667, but to 'simplify' it, you just get 1.66 dollars per liter.

Therefore, the answer is 1.66$ per liter.

Answer:

1/1/4<−2/2/4, because 1/1/4 is located to the right of −2/2/4 on the number line.

Step-by-step explanation:

Answer:

La ordenada de Q es 7.

Step-by-step explanation:

La ecuación de una recta es:

y = a*x + b

donde a es la pendiente y b es la ordenada al origen.

Para este problema, sabemos que la pendiente es -2

Entonces:

a = -2

y = -2*x + b

También sabemos que esta recta pasa por el punto (5, -1)

Esto significa que cuando evaluamos la ecuación en x = 5, y toma el valor y = -1

Si reemplazamos esos valores en la ecuación, obtenemos:

-1 = -2*5 + b

-1 = -10 + b

-1 + 10 = b

9 = b

Entonces la ecuación de la recta es:

y = -2*x + 9

Sabemos que el punto Q está en la línea, y la abscisa de este punto es 1.

Entonces este punto es Q (1, k)

donde k es la ordenada de este punto.

Porque nuestra línea también pasa por este punto, podemos concluir que cuando x = 1, y = k

Reemplazando eso en la ecuación tenemos:

k = -2*1 + 9 = -2 + 9 = 7

k = 7

La ordenada de Q es 7.

Answer:

Circumference= 50.27

Answer:

Step-by-step explanation:

the third one

Answer:

1261.1 revolutions

Step-by-step explanation:

Given

[tex]d = 16in[/tex] --- the diameter

[tex]Distance = 5280ft[/tex]

Required

The number of revolution completer

First, calculate the circumference (c) of the tire

[tex]c = \pi d[/tex]

[tex]c = 3.14 * 16[/tex]

[tex]c = 50.24[/tex]

Let the number of revolutions be n.

The product of n and the circumference equals to the total distance travelled.

So:

[tex]c * n = 5280 ft[/tex]

[tex]50.24in* n = 5280 ft[/tex]

Make n the subject

[tex]n = \frac{5280 ft}{50.24in}[/tex]

Convert feet to inch

[tex]n = \frac{5280 *12in}{50.24in}[/tex]

[tex]n = \frac{63360in}{50.24in}[/tex]

[tex]n = \frac{63360}{50.24}[/tex]

Solve for n

[tex]n = 1261.14649682[/tex]

Approximate

[tex]n = 1261.1[/tex]

Answer:

The monthly payment is approximately $2,356.89

Step-by-step explanation:

The list price of the car, P = $41,070

The interest rate payed, r = 5.09% compounded monthly

Therefore, the number of interest calculated per period, n = 1

The payment period, t = 5 years

The amount payed as sales tax = 5.86%

The amount paid as registration fee = $384

The amount paid as documentation fee = $89

The total amount to be paid, A = 41,070 + 41,070 × 0.0586 + 384 + 89 = 43,949.702

Therefore, the monthly payment, 'M', is given by the following formula;

[tex]M = \dfrac{P \cdot \left(\dfrac{r}{n} \right) \cdot \left(1+\dfrac{r}{n} \right)^{n \cdot t} }{\left(1+\dfrac{r}{n } \right)^{n \cdot t} - 1}[/tex]

Therefore, we get;

[tex]M = \dfrac{43,949.702\times \left(\dfrac{0.0509}{1} \right) \cdot \left(1+\dfrac{0.0509}{1} \right)^{1 \times 60} }{\left(1+\dfrac{0.0509}{1 } \right)^{1 \times 60} - 1} \approx 2,356.89[/tex]

The monthly payment, M ≈ $2,356.89.

Answer:

f(2) = -3

f(0) = -5

f(-1) = -6

f(1) = -4

f(8) = 3

f(5) = 0

Step-by-step explanation:

us the f value and substitute for x.

1) f(1)= 1 - 5 = -4

2) f(-1) = -1 -5 = -6

3) f(2) = 2 - 5 = -3

4) f(0) = 0 - 5 = -5

5) f(5) = 5 - 5 = 0

6) f(8) = 8 - 5 = 3

then match the f value with the correct answer

The Answer Is Sin(B)=4/5

[tex] \sin( \beta ) = \frac{opposite}{hypotenuse} [/tex]

Meaning, sin(B)=4/5

Answer:

4/5

Step-by-step explanation:

The angle you want to look at is the one given to you with the beta symbol. The trigonometric funtion sin mean opposite/hypotenuse. The side that is opposite is stright across from ∠β which would be 4. The hypothenuse is the largest side of the triangle or the "slanted side of the triangle." With that explanation, the hypotenuse is 5.
