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

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
I will mark Brainiest (no links please)
Answer:
Step-by-step explanation:
Are the volumes equal? No, so throw out the first and the last one.
Is the volume of the pyramid greater than the volume of prism?
No, so throw out the third one
so by inspection it must be the remaining one
or mathematically
vol pyramid = (1/3)(base)(height)
vol prism = (base)(height)
vol pyramid / vol prism
(1/3)(base)(height) / (base)(height) = 1/3

Actually Welcome to the Concept of the Angle sum property of a Triangle.
hence,
==> 4x + 8° + 60° + 60° = 180
==> 4x + 128° = 180°
==> 4x = 180 - 128
==> 4x = 52°
==> x = 52/4
==> x = 13°
hence the value of x = 13 °

−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.

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

a) The upper bound for the area of the rectangle.
b) The lower bound for the perimeter of the rectangle.
Answers:
Part (a) upper bound for area = 4527.7056 square cmPart (b) lower bound for perimeter = 278 cm======================================================
Explanation:
Part (a)
The horizontal portion is shown to be 87.3 cm long. This is the result after rounding has occurred. Specifically, rounding to one decimal place (tenths). The question is: What could the number have been before rounding?
You have to think in reverse of the usual rounding process.
The values 87.25, 87.26, 8.27, ... 8.33, 87.34 all round to 87.3 when we round to one decimal digit. Note the hundredths digit is increasing by 1 each time. We can see that 87.34 is the largest possible value for the horizontal piece. After that, 87.35 will round to 87.4 which is just out of reach.
Through similar logic/reasoning, the vertical side can be at most 51.84 cm.
The area of the rectangle could be 87.34*51.84 = 4527.7056 which is the upper bound for the area. This is the largest possible area, given the values in the diagram, since we made each value as large as possible.
In short, 4527.7056 square cm is the max area.
-----------------------------------
Part (b)
We use the idea of part (a), but we'll use the smallest possible values this time.
So we go with 87.25 for the horizontal portion and 51.75 for the vertical portion.
Compute the perimeter with these smallest dimensions.
P = 2*(length + width)
P = 2*(87.25 + 51.75)
P = 278
The smallest perimeter possible is 278 cm which is the lower bound of the perimeter. This is guaranteed to be the smallest perimeter possible because we made the sides as small as possible, while staying in the restrictions as discussed in the previous section.
