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
solve and get brainliest!!
please be sure of your answer!!!!
Answer:
B
Step-by-step explanation:
all 3 angles of a triangle must equal 180 degrees, so if it tell you that there is a 68 degree angle, and a 90 degree angle(because if the right angle), then the last angle must be 22, because 180-(68+90)=22

wages have been rising at 6% per year in your area. if this continues, how much will you need to pay you $14 per hour employees in two years
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.
What is a percentage?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.

A restaurant chef was ordering supplies. He ordered 9 pounds of beef at 7.53 per pound, 9 pounds of potatoes at $6.45 a pound and 4 pounds of carrots at $6.23 per pound. He estimates that this will make 27 meals. If he charges 39.53 per meal how much profit will he make
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
−2x=x2−6 Rewrite the equation by completing the square.
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:

Step-by-step explanation:
36/32 simplified is 9/8.
8 + 7(3+11), I'm assuming it's not x.
8 + 7(14) = 106
(9/8)/106 = 9/8*106 = 954/8 = 119.25

David is considering changing his car to one which used liquefied
petroleum gas (LPG). A litre of LPG costs £0.62 and a litre of petrol
costs £1.29. What is the cost of a litre of LPG as a percentage of the
cost of a litre of petrol (give your answer to the nearest whole number)?
Answer:
48%
Step-by-step explanation:
A liter of LPG costs £0.62
A liter of petrol costs £1.29.
Therefore,
The cost of a liter of LPG as a percentage of the cost of a liter of petrol is calculated as:
Cost of LPG/ Cost of Petrol × 100
= £0.62/£1.29 × 100
= 48.062015504%
Approximately to the nearest whole number = 48%
