si el area del cuadrado es de 80 m cuanto vale la m​

Answer:

14 cupcakes

Step-by-step explanation:

75% is equivalent to 3/4 so 56 divided by 4 times by 3

56 divided by 4 is 14 X 3 = 42

56-42 leaves you with 14 cupcakes

Step-by-step explanation:

Answer:

The interest will be $30, the total amount she pays will be $530.

Step-by-step explanation:

500 x 0.06

30 = the interest rate cost

500 + 30 = $530

$530 is the total amount Victoria needs to pay, and the interest rate cost is $30.

Answer:

Option B, There is no correlation between the last digit of phone number and the quiz grade.  

Step-by-step explanation:

The values on the scatter plot are dispersed and hence no best fit curve can be drawn for this data set.

Hence there is no relation between the two variables that is last digit of phone number and the quiz grade.  

Answer:

Yeah what he said

Step-by-step explanation:

Answer:

Let x be the width of the screen and

x + 30 be the length of the screen

Area of the screen = 10384 square feet

=>x(x+30) = 10384

x^2 + 30x = 10384

x^2 + 30x - 10384 = 0

Splitting-

x2+118x - 88x -10384 = 0

x(x+118) -88(x+118) = 0

(x+118)(x-88) = 0

x=-118,88

Since width should be positive,

width = 88 feet

length = 118 feet

Step-by-step explanation:

If it costs $25 for two hours and we want 6 hours, we simply multiply it by 3 because 6/2 = 3.

$25 * 3 = $75

Answer:

The answer $75

Step-by-step explanation:

you add $25 each 2 hours and it would be $75 simple

  -3 ≤ -1

  -3 < -1

Answer:

no solution.

Step-by-step explanation:

2x + 3x + 9 < 5x - 7

5x + 9 < 5x - 7

5x + 9 - 9 < 5x - 7 - 9

5x < 5x - 16

5x - 5x < 5x - 16 - 5x

Answer:

hgkgbnnhm,

Step-by-step explanation:

The arc length of [tex]y=2x^{\frac32}[/tex] over [0, 1] is given by the integral,

[tex]L=\displaystyle\int_0^1\sqrt{1+\left(\frac{\mathrm dy}{\mathrm dx}\right)^2}\,\mathrm dx[/tex]

Differentiate y with respect to x using the power rule:

[tex]\dfrac{\mathrm dy}{\mathrm dx}=\dfrac32\times2 x^{\frac32-1}=3x^{\frac12}[/tex]

Then the integral becomes

[tex]L=\displaystyle\int_0^1\sqrt{1+\left(3x^{\frac12}\right)^2}\,\mathrm dx=\int_0^1\sqrt{1+9x}\,\mathrm dx[/tex]

Substitute u = 1 + 9x and du = 9 dx :

[tex]L=\displaystyle\int_0^1\sqrt{1+9x}\,\mathrm dx=\frac19\int_1^{10}\sqrt u\,\mathrm du[/tex]

[tex]L=\displaystyle\frac19\left(\frac23u^{\frac32}\right)\bigg|_1^{10}[/tex]

[tex]L=\dfrac2{27}\left(10^{\frac32}-1^{\frac32}\right)[/tex]

[tex]L=\boxed{\dfrac2{27}\left(10^{\frac32}-1\right)}[/tex]

Step-by-step explanation:

(f + g)(x) = f(x) + g(x)

= (2x² - 9x) + (3x - 2) = 2x² - 6x - 2.

Therefore (f + g)(3) = 2(3)² - 6(3) - 2 = -2.

(f - g)(x) = f(x) - g(x)

= (2x² - 9x) - (3x - 2) = 2x² - 12x + 2.

Therefore (f - g)(-4) = 2(-4)² - 12(-4) + 2 = 82.

(g o f)(x)

= g(2x² - 9x) = 3(2x² - 9x) - 2 = 6x² - 27x -2.

(f o g)(x)

= f(3x - 2) = 2(3x - 2)² - 9(3x - 2) = 18x² - 51x + 26.

Answer:

[tex] \frac{28}{12} = \frac{(28 \div4)}{(12 \div 4)} = \frac{7}{3} =\boxed{7:3}✓ \\ [/tex]

A ratio of 28 to 12 can be expressed in simplest form as:

(1) 8:5

(2) 7:3✓

(3) 9:4

(4) 14:9

Answer:

x = 13

Step-by-step explanation:

110° is the vertically opposite angle of one of the interior angles of the given triangle.

Therefore,

[tex]x \degree + 57 \degree + 110 \degree = 180 \degree \\ \\x \degree + 167 \degree = 180 \degree \\ \\ x \degree = 180 \degree -167 \degree \\ \\ x \degree = 13 \degree \\ \\ x = 13[/tex]

Answer:

The price was marked down by 12.58%

Step-by-step explanation:

153.77 is a 12.581011938601% decrease of 175.90.

Percentage of decrease = |175.90 - 153.77|/175.90 = 22.13/175.90 = 0.12581011938601 = 12.581011938601%

Step-by-step explanation: ok

Step-by-step explanation:

2 * (1/4) + (3/4)

= (2/4) + (3/4)

= 5/4 or 1.25.

Answer:

5/4

Step-by-step explanation:

First multiply 2 x 1/4

so you would do 2/1 x 1/4

and so that would give you 2/4

and then it would be 2/4 +3/4

and since they have the same denominator

add the numerator which will give you 5/4 or 1 1/4

Answer:

Step-by-step explanation:

For parallelogram, the opposite sides are equal. Hence

2x + 4 = 6x - 16

Collect the like terms

2x - 6x = -16 - 4

-8x = -20

x = 20/8

x = 5/2

x = 2.5

Hence the value of x is 2.5

Answer:

x < -1

Step-by-step explanation:

if he substituded 0 for x into the inequality, he gets 3>4. then he should notice it is incorrect so the riht way to solve is to use subtracting property of inequality and subtract 4 from both sides and get -1 > x

Answer:

the answer would actually be x< -1 then he should've checked his work by replacing the x with -1

Answer:

x = 6

Step-by-step explanation:

Let's solve your equation step-by-step.

6−8x=7x−10x−24

Step 1: Simplify both sides of the equation.

6−8x=7x−10x−24

6+−8x=7x+−10x+−24

−8x+6=(7x+−10x)+(−24)(Combine Like Terms)

−8x+6=−3x+−24

−8x+6=−3x−24

Step 2: Add 3x to both sides.

−8x+6+3x=−3x−24+3x

−5x+6=−24

Step 3: Subtract 6 from both sides.

−5x+6−6=−24−6

−5x=−30

Step 4: Divide both sides by -5.

−5x/-5 = -30 /-5

x=6
