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:

(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.

64 is the right answer of your question

Answer:

95 degrees

Step-by-step explanation:

The sum of two supplementary angles is 180 degrees

Given

angle 1 = 85 degrees

If angle 2 is the supplement of angle 1, then

<1 + <2 = 180

85 + <2 = 180

<2 = 180 - 85

<2 = 95degrees

Hence the measure of angle 2 is 95 degrees

Total Budget: $1200

Step-by-step explanation:

76% = 912

1% = 12

100% = 12 x 100 = $1200

I brute forced till I got the number which multiplied by 76 came out to 912 from there I had what was 1% of the budget then I multiplied that by 100 for the answer.

The total budget for their student film is $1200.

A percentage is a number or ratio that can be expressed as a fraction of 100.

A group of friends were working on a student film.

They spent all their budget on props and equipment.

They spent $912 on props, and 24% of the total budget on equipment.

Let us represent the total budget of the film as: x

The amount spent on equipment = $870

The amount spent on props = 24% of x

Total budget = Amount spent on equipment + Amount spent on props

x = 912 + 24% of x

x = 912 + 0.24x

x - 0.24x = 912

0.76x = 912

x= 912/0.76

x = $1200

Hence, the total budget for their student film is $1200.

Answer:

150 miles

Step-by-step explanation:

The movements are represented as:

[tex]N1 = 30miles[/tex]

[tex]E1 = 40miles[/tex]

[tex]N2 = 60miles[/tex]

[tex]E2 = 80miles[/tex]

Required

Determine the distance from the starting point

The student's movement is illustrated with the attached image.

First, calculate the total distance towards North.

[tex]N = N1 + N2[/tex]

[tex]N = 30 + 60[/tex]

[tex]N = 90[/tex]

Next, calculate the total distance towards East

[tex]E = E1 + E2[/tex]

[tex]E = 40 + 80[/tex]

[tex]E = 120[/tex]

The total distance from the starting point is calculated using Pythagoras theorem.

[tex]D^2 = N^2 + E^2[/tex]

[tex]D^2 = 90^2 + 120^2[/tex]

[tex]D^2 = 22500[/tex]

[tex]D = \sqrt{22500[/tex]

[tex]D = 150[/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
