[tex]c = \sqrt{52}[/tex]

Step-by-step explanation:

[tex]c^{2} = a^{2} + b^{2}[/tex]

[tex]c^{2} = 4^{2} + 6^{2}[/tex]

[tex]c^{2} = 16 + 36\\[/tex]

[tex]c^{2} = 52[/tex]

[tex]\sqrt{c^{2} } = \sqrt{52}[/tex]

[tex]c = \sqrt{52}[/tex]

Answer:

916.57 pounds

Step-by-step explanation:

Cost of beef = 7.53 pounds × 9

= 67.77 pounds

Cost of potatoes = 6.45 pounds × 9

= 58.05 pounds

Cost of carrots = 6.23 pounds × 4

= 24.92 pounds

Total cost = 67.77 pounds + 58.05 pounds + 24.92 pounds

= 150.74 pounds

Total revenue = 27 meals × 39.53 pounds

= 1067.31 pounds

Total profits = Total revenue - Total cost

= 1067.31 pounds - 150.74 pounds

= 916.57 pounds

Answer:

Answer:

(x + 1)² = 7

Step-by-step explanation:

Given:

-2x = x² - 6

We'll start by rearranging it to solve for zero:

x² + 2x - 6 = 0

The first term is already a perfect square so that's fine.  Normally, if that term had a non-square coefficient, you would need to multiply all terms a value that would change that constant to a perfect square.

Because it's already square (1), we can simply move to the next step, separating the -6 into a value that can be doubled to give us the 2, the coefficient of the second term.  That value will of course be 1, giving us:

x² + 2x + 1 - 1 - 6 = 0

Now can group our perfect square on the left and our constants on the right:

x² + 2x + 1 - 7= 0

x² + 2x + 1 = 7

(x + 1)² = 7

To check our answer, we can solve for x:

x + 1 = ± √7

x = -1 ± √7

x ≈ 1.65, -3.65

Let's try one of those in the original equation:

-2x = x² - 6

-2(1.65) = 1.65² - 6

- 3.3 = 2.72 - 6

-3.3 = -3.28

Good.  Given our rounding that difference of 2/100 is acceptable, so the answer is correct.

Answer:

x would most likely be 55.

Explanation:

because it is a right angle which is = to 90.

90-35=55

Answer:

55°

Step-by-step explanation:

Right angles are 90°

90 - 35 = 55° (x°)

The angles are adjacent, if it was vertical both angles would have the same degree. Adjacent angles are angles which have a common vertex and occur in right angled triangles.

Answer:

15.73

Step-by-step explanation: I just kinda guessed and got it right.

You need to pay $15.73  per hour to employees in next two years.

A ratio or value that may be stated as a fraction of 100 is called a percentage. And it is represented by the symbol '%'.

Given:

Wages have been rising at 6% per year in your area.

Next year, you need to pay employees,

= 14 + 14 x 6/100

= $14.84

Again next year,

you need to pay = 14.84 + 14.84 x 6/100

= $15.73

Therefore, the wage is $15.73 per hour to employees.

Answer:

x = 5

Step-by-step explanation:

To get the value of x we will use similar triangles as shown;

AT/AG = AB/AC

9/3 = x+10/3x-10

Cross multiply

3(x+10) = 9(3x-10)

3x + 30 = 27x - 90

Collect like terms

3x - 27x = -90 - 30

-24x = -120

x = 120/24

x = 5

Hence the value of x is 5

Answer:

70 is 125% of 50

Step-by-step explanation:

I hope this helped :)

The percentage value of 70 to  56 is 125% by taking the ratio of 70 to 56 and then converting it to a percentage.

Given that, to find what percent of 70 in 56.

To find out if the percentage of 70 is 56, follow the steps:

Step 1:Find the ratio of the two numbers that is the ratio of  70 and 56 gives:

[tex]70:56 = 70/56[/tex]

Divide both numerator and denominator by 14 yields in:

[tex]= 5/4[/tex]

Step 2: Convert the result of step 1 into decimals by a long division of  5 by 4.

[tex]5/4 = 1.25[/tex]

Step 3: Find the percentage value of the decimal by multiplying the decimal by 100.

[tex]1.25 \times100 = 125[/tex]%

Therefore, the percentage value of 70 to  56 is 125% by taking the ratio of 70 to 56 and then converting it to a percentage.

the equation would be 2[6]+10 however if we were to solve it would have been 2(6)+10 = 22 employees

The equation y = 4/3 x + 2 represents the number of employees, increases at a steady rate.

Where x shows the number of months

An equation is a combination of different variables, in which two mathematical expressions are equal to each other.

Given that,

At staring, when the company was opened,

The number of employees = 2.

After 6 months the number of employees in company = 10.

The increased number of employees = 10 - 2 = 8

In 6 months 8 employees are increases.

In 12 months number of employees = 10 + 8 = 18

Let y represents the number of employees

And x represents the number of months

So the equation can be written as,

y = 4/3 x + 2

The required equation is y = 4/3 x + 2.
