find m<1 m<2 138
i did it asappp,thank you
Answer:
mΔ1 = 42°
mΔ2 = 42°
Step-by-step explanation:
Δ1 + 138° = 180°
Δ1 = 180° - 138°
Δ1 = 42°
______________Δ2 + 138° = 180°
Δ2 = 180° - 138°
Δ2 = 42°
Brianna's parents built a swimming pool in the backyard. Brianna says that the distance around the pool is 120 feet.
40 Ft
2011
1. Is she correct? Explain why or why not. (Your explanation needs to include the following: If she is correct, show what she
did to find the distance around the pool. If she is not correct, find the correct distance, showing all work.)
2. Explain (using words this time) how Brianna would determine the distance around the pool so that her parents would
know how many feet of stone to buy for the edging around the pool.
No, Brianna is not correct.
The distance around the pool is 131.4 ft
What is perimeter of semicircle?The perimeter of a semicircle is the sum of half of the circumference of the circle and its diameter. As the perimeter of a circle is 2πr or πd. So, the perimeter of a semicircle is 1/2 (πd) + d or πr + 2r, where r is the radius, and, 2r=d is diameter.
P=(πr + 2r)
here, we have,
1) Semi circle with a diameter equal to the side opposite it, 20 ft.
Find the length of half the circle:
Circumference of semi-circle = (1/2)(πd)
Where:
π = 3.14
d = 20 ft.
Circumference of semi-circle = (1/2)(3.14)(20 ft) = 31.4 ft.
2) Vertical lengths from the endpoint of semi-circle to the endpoints of horizontal lengths, 40 ft each ⇒ 2 × 40 ft. = 80 ft.
3.) Horizontal length at 20 ft.
Add the semi-circle, vertical, and horizontal lengths:
Distance around the pool = 31.4 ft + 80 ft. + 20 ft.
Distance around the pool = 131.4 ft.

An employee sells ten tablets for $149.99 each. How much will he make if he earns 4.5% commission?
Answer:
67.50
Step-by-step explanation:
If he makes 4.5 percent on each tab, 149.99x .045 is 6.75 per tablet. 6.75 times 10 is 67.50
Answer: $67.50
Steps:
149.99 * .045 = 6.75
6.75 * 10 = 67.50
Which graph shows a linear function?
Answer:
There is no graph but the graph that would have a straight line
Answer:
Whichever line is straight and does not have x repeat itself is considered linear.
Step-by-step explanation:
A linear function can be shown by using the equation y=mx+b, in which m is the slope and b is the y-intercept. A linear function must be able to follow this formula in order to be considered linear. An exponential equation, quadratic equation, or other equation will not work.
Chances are, if the line is straight and the points plotted can be connected within a straight line and not overlap, they are a linear function.
[A function being an equation in which x does not repeat itself, therefore a vertical line up and down is not considered a linear function, however, a horizontal line is.]
f(x) = x^2. What is g(x)?
please answer quick i’ll give brainliest
Answer:
-x² - 3
Step-by-step explanation:
If a function is concave down, that means the x value is negative.
Hence we know that it should be -x²
The graph is translated 3 units down
Hence:
-x² - 3
I need help with this somebody please help!!
Answer:
answer is:
Circum: 25.13274 cm^2
Area: 50.26548 cm^2
Step-by-step explanation for the CIRCUMFERNCE ONLY:
Original equation for the circumference of a circle:
C=2(pi)r
We will use 3.14 as pi
We know that the diameter of a circle is 2 times the radius, so in order to find the radius all we have to do is divide the diameter by 2.
8/2 = 4
So now we know what the radius is equal to.
4
So now just plug in your numbers to the original equation
2 X (3.14) X 4
25.13274
If we were to round up the answer would be
25.13

Someone help me with this please I will give brainliest
Answer:
No
Step-by-step explanation:
10 kilograms = 22 pounds
23 kilograms = ? pounds
so for this you would need to cross multiply:
(22 * 23) = 506
(10 * x ) = 10x
--> 506 = 10x
Next step is to isolate the varible (x), to do that you need to divide by 10.
x = 506/10 = 50.6
50.6lbs is more than 50lbs so no it can't get checked out

PLEASE HELP IM CONFUSED. Is this relation a function? Justify your answer.
A. Yes, because every x-value corresponds with a single y-value.
B. Yes, because every x- and y-value is positive.
C. Yes, because the number of x values is the same as the number of y-values.
D. No, because two points with the same y-value have different x-values.

Put the following equation of a line into slope-intercept form, simplifying all fractions. 3x + y = 3
Answer:
y = - 3x + 3
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c
Given
3x + y = 3 ( subtract 3x from both sides )
y = - 3x + 3 ← in slope- intercept form
Answer:
y=-3x+3
Step-by-step explanation:
3x+y=3
y=3-3x
y=-3x+3
Find the perimeter of the triangle below
Danny purchased a large wheel of cheese at the farmer's market.What is the volume of the cheese, to the nearest cubic inch ?
Answer:
1105.84 in³
Step-by-step explanation:
The volume of the wheel can be obtained using the formular for the volume of a cylinder :
V = πr²h ;
Height, h = 5.5 in
Radius, r = 8 in
V = π * 8² * 5.5
V = π * 64 * 5.5
V = π * 352
Volume of wheel = 1105.8406 in³

Answer:
The highest rate of birds is during the years 4 to 3
(remember that the lowest digit of number of negative is the highest and the highest is the lowest)
Step-by-step explanation:
Rate of Changes:
1 to 2: 5080.86 - 5238/ 2 - 1
= -157.14/1
= (convert to decimal) -157.1
2 to 3: 4928.43 - 5080.86/ 3 - 2
= -152.43/ 1
= -152.43
3 to 4: 4780.58 - 4928.43/ 4 - 3
= -147.85/ 1
= -147.85
