Answer:
the cost of labor per hour is $55
Step-by-step explanation:
Let C = cost of labor per hour
Let h = hours worked
Let p = cost of parts
Let t = total price
[tex]c = \frac{t - p }{h} \\\\c = \frac{309.50 - 62}{4.5} \\\\c = \frac{247.50}{4.5} \\\\c = 55[/tex]

Please help!! What is the area to this figure??
Answer:
318
Step-by-step explanation:
find area of the big triangle then split the remaining shape into a large rectangle and a smaller rectangle
Answer:
318 mi²
Step-by-step explanation:
Formulae
Area of a rectangle = width x length
Area of a triangle = 1/2 x base x height
Divide the figure into 1 triangle and 2 rectangles (see attachment).
Area of Triangle 1 = 1/2 x (10 + 6 + (11 - 8)) x 22
= 1/2 x 19 x 22
= 209 mi²
Area of Rectangle 2 = 5 x (11 + 6)
= 85 mi²
Area of Rectangle 3 = 4 x 6
= 24 mi²
Total area = 209 + 85 + 24 = 318 mi²

to find:how far the airplane can travel in an hour.
solution:x= v × t
x= 820 × 1
x= 820 miles
so, the airplane can travel 820 miles per hour.
A tee shirt company charges $240 for 12 tee shirts. They charge the same amount of money for each shirt.
Which table represents the relationship between the number of tee shirts the company sells and the amount of money they charge?
Number of shirts Amount charged (dollars)
2 $24
4 $48
6 $72
8 $96
Number of shirts Amount charged (dollars)
5 $100
10 $200
15 $300
20 $400
Number of shirts Amount charged (dollars)
10 $240
11 $240
12 $240
13 $240
Number of shirts Amount charged (dollars)
12 $240
14 $264
16 $288
18 $312
Step-by-step explanation:
$240 for 12 t-shirts.
that means 240/12 = $20 per shirt.
therefore, only the second option (with $100, $200, $300, $400) is correct. when adding 5 shirts, the price goes up 5×$20 = $100.
all the other options use a different unit price.
In the figure, AC = BC. Find the value of b.
Since AC = BC, we can say that this triangle is isoceles (at C)
In an isoceles triangle, the two angles that does not belong to the top angle (which in this case is C) is equal to each other.
Now, we can find the sum of the 2 missing angles : 180 - 52 = 128.
And since they are equal, we can find b : 128 : 2 = 64/

The height, h, in feet of the tip of the minute hand of a wall clock as a function of time, t, in minutes can be modeled by the equation h = 0.75 cosine (startfraction pi over 30 endfraction (t minus 15)) 8. which number (from 1 to 12) is the minute hand pointing to at t = 0? 3 6 9 12
The height of the tip of the minute hand of a wall clock is 9 ft. Then the correct option is C.
What is a function?The function is an expression, rule, or law that defines the relationship between one variable to another variable. Functions are ubiquitous in mathematics and are essential for formulating physical relationships.
The height, h, in feet of the tip of the minute hand of a wall clock as a function of time, t, in minutes can be modeled by the equation
[tex]h =0.75 \cos \left ( \dfrac{\pi}{30(t-15)} \right ) + 8\\[/tex]
When t = 0, then the value of the h will be
[tex]h =0.75 \cos \left ( \dfrac{\pi}{30(0-15)} \right ) + 8\\\\\\h =0.75 \cos \left ( \dfrac{\pi}{-450} \right ) + 8\\\\\\h =0.75 \cos \times 0.9999+ 8\\\\\\h = 0.74998+8\\\\\\h = 8.74889 \approx 9[/tex]

if the simple interest on $800 for 3 years is $60, what is the rate of interest per annum
Answer:
2.5%
Step-by-step explanation:
Simple interest formula
I = Prt
where:
I = total interestP = principalr = interest rate (in decimal form)t = time (in years)Given:
I = $60P = $800t = 3 yearsSubstituting given values into the formula and solving for r:
⇒ 60 = 800 · r · 3
⇒ 60 = 2400r
⇒ r = 0.025
Converting r to percentage:
0.025 × 100% = 2.5%
Answer:
2.5%
Step-by-step explanation:
Given:
Principle: $800Time: 3 yearsSimple interest: $60Formula:
Simple interest = (Principle × Rate × Time)/100
Substitute the principle, time and the interest in the formula to determine the rate of interest per annum.
[tex]\implies 60 = \dfrac{ (800 \times \text{Rate} \times 3)}{100}[/tex]
Divide 100 to 800 as 800 is the only number in the equation that is divisible by 100.
[tex]\implies 60 ={ (800 \div 100)\times \text{Rate} \times 3}[/tex]
[tex]\implies60 ={ 8\times \text{Rate} \times 3}[/tex]
Simplify both sides of the equation:
[tex]\implies60 ={ 24\times \text{Rate}}[/tex]
Divide both sides by 24.
[tex]\implies\dfrac{60}{24} =\dfrac{{ 24\times \text{Rate}}}{24}[/tex]
Simplify both sides as needed:
[tex]\implies\dfrac{60}{24} = \text{Rate}[/tex]
[tex]\implies\dfrac{60 \div 12}{24 \div 12} = \text{Rate}[/tex]
[tex]\implies \text{Rate} = \dfrac{5}{2} = 2.5[/tex]
Thus, the rate of interest per annum is 2.5%.
find the value of x
Answer:
82•5°
Step-by-step explanation:
[tex]28 + 68.5 + x = 180[/tex]
[tex]x = 180 - 97.5[/tex]
[tex]x = 82.5[/tex]
Here,
let the forth degree of the quadrilateral be y
Then,
90° +90° +68.5° + y =360° (all the interior angle of a quadrilateral is 360°)
or, 248.5+ y=360°
or, y = 360° - 248.5°
or, y= 111.5°
Again, the second angle of the triangle be a
Then,
a=111.5(vertically opposite angle)
Lastly,
29° + 111.5° + x = 180°(all the interior angle of a triangle is 180°)
or, 140.5° + x = 180°
or, x =180° - 140.5°
or, x=39.5°

Please Help Meeeee!!! Will Mark Brainliest!!!
Answer:
Part A: Yes. For every 10 employees, an increase of 80 products produced.
Part B: y = 8x + 120
Part C: Y-intercept indicates the number of products produced when there are 0 employees. The slope indicates the rate of increase of production with the number of employees
Step-by-step explanation:
Part A: 80 - 0 = 80 employees; 760 - 120 = 640 products. Therefore, 640/80 = 8 products per employee or 80 products per 10 employees
Part B: For y = mx + c ,
m = (Y1 - Y0)/(X1 - X0) = (760 - 120)/(80 - 0) = 8
c = Y-intercept, when X = 0. Therefore c = 120

2 * -9 = -18. We need 2 numbers whose product is -18 and whose sum is -3. They are -6 and + 3. So:
= 2x^2 - 6x + 3x - 9
= 2x(x - 3) + 3(x - 3)
= (2x + 3)(x - 3)
2) 3x^2 + 5x +2
Now 3 * 2 = 6 We need to numbers whose product is + 6 and whose sum is +5. Theres are + 3 and + 2>
= 3x^2 + 3x + 2x + 2
= 3x(x + 1) + 2(x + 1)
= (3x + 2)(x + 1)
