Answer:
[tex] - 32[/tex]
Step-by-step explanation:
1) Simplify
[tex] \sqrt{32} \: to \: 4 \sqrt{2} [/tex]
[tex] - 8 \sqrt{2} \times \frac{1}{2} \times 4 \sqrt{2} [/tex]
2) Use this formula: a/b × c/d = ac/bd.
[tex] - \frac{8 \sqrt{2} \times 1 \times 4 \sqrt{2} }{2} [/tex]
3) Simplify.
[tex] - \frac{32 \sqrt{2 \sqrt{2} } }{2} [/tex]
4)
[tex]simplify \: 32 \sqrt{2 } \sqrt{2} \: to \: 32 \sqrt{4} [/tex]
5) Since 2 × 2 = 4, the square root of 4 is 2.
[tex] - \frac{32 \times 2}{2} [/tex]
6) Simplify 32 × 2 to 64.
[tex] - \frac{64}{2} [/tex]
7) Simplify 64/2 to 32.
[tex] - 32[/tex]
Therefor, the answer is option three -32

3. The figure below is a composite shape that consists of a semicircle and an equilateral triangle (triangle
with sides that are all equal). Find the perimeter and area of the composite shape. Use 3.14 for pi.
Perimeter:
4cm
5cm
Area:
Answer:
See explanation below
Step-by-step explanation:
Area = Area of triangle + Area of the semi circle
Area of triangle = 1/2bh
Area of triangle = 1/2 *(5/2)(4)
Area of triangle = 1/2(2.5)*4
Area of triangle = 2 * 2.5
Area of triangle = 5cm^2
Area of semicircle = πr²/2
r = 2.5cm
Area of semicircle =(3.14)(2.5)²/2
Area of semicircle = = 3.14 * 4.5
Area of semicircle = 9.8125cm^2
Area pf the figure = 5+9.8125
Area pf the figure = 14.8125cm^2
For the perimeter
Perimeter of the semicircle = 2πr
Perimeter of the semicircle = 2(3.14)(2.5)
Perimeter of the semicircle = 15.7cm
Perimeter of the semicircle = = 15.7 + 5 + 5
Perimeter of the semicircle = 25.7cm

question 1. What will Amanda pay if she rents a truck and drives 45 miles and splits the total cost with two friends? Explain with details?
question 2. find the interpret the slope for the graph.
question 3. how much does it cost to rent a truck for a day?
please answer please I really need the answer asap
Answer:
A) Amanda will pay $47.5
B) 0.5
C) $120
Step-by-step explanation:
A) From the graph given, at 45 miles, the total cost of rentage = $142.50
She now splits this cost with 2 of her friends. Thus each of them will pay;
Amount = 142.5/3 = $47.5
So,Amanda will pay $47.5
B) To find the slope, we will pick two points on the graph and use their respective coordinates to find the slope.
Coordinates we pick are;
(0, 120) and (50, 145)
Thus, slope; m = (y2 - y1)/(x2 - x1)
m = (145 - 120)/(50 - 0)
m = 25/50
m = 0.5
C) The equation for the graph will now be; y = mx + c
Where m is slope and c is y - intercept.
Thus;
y = 0.5x + 120
Coincidentally, c = 120 will be the fixed price of the truck while 0.5x will be the variable cost depending on how many miles are driven.
Thus renting for a day is simply the fixed cost of $120

an angle is 22 degrees smaller than a second angle. the two angles are complementary. what is the measure of the smaller angle?
Let the first angle be x°.
Then the second angle shall be (x - 22)°.
The two angles are complementary. Hence their sum shall be 90°.
First angle + second angle = 90°
=> x° + x° - 22° = 90°
=> 2x° = 112°
=> x° = 56°
Hence first angle = x° = 56°.
Second angle = (x - 22)° = 34°.

A truck rental company charges $35 per day to rent a truck plus $.35 per mile driven. James rented a truck for three days. The total cost was $191.10. How many miles did James drive the
truck?
Answer:
246miles
Step-by-step explanation:
pls give brainliest :)
Answer:
246 miles
Step-by-step explanation:
$191.10-$105 (105 is the total cost of truck rental for 3 days)
=$86.1

Slope intercept form of points 0, -4 and -1, 4
Answer:
[tex]y=\frac{0}{-1} -4[/tex]
Step-by-step explanation:
first, you have to find the slope, and to do that you use this equation [tex]\frac{y2-y1}{x2-x1}[/tex]
so, now to insert your points (0,-4), (-1,4)
(x1,y1) (x2,y2)
[tex]\frac{4-4}{-1-0} = \frac{0}{-1}[/tex]
now that you have the slope you can find the y-intercept of the slope-intercept form by looking at your first point (0,-4) and get -4
- if you were to look at this point on a graph it would be on the y-axis therefore, -4 is the y-intercept [if you don't have a point like this one then you can look at a graph with one of your points and make a slope until you are on the y-axis :)]
therefore, the slope-intercept form is y=[tex]\frac{0}{-1}[/tex] -4
[ps, your slope is a zero slope :)]
Answer:
y = - 8x - 4
Step-by-step explanation:
y = mx + b
"m" is slope, "b" is y-intercept.
( [tex]x_{1}[/tex] , [tex]y_{1}[/tex] )
( [tex]x_{2}[/tex] , [tex]y_{2}[/tex] )
m = [tex]\frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]
~~~~~~~~~~~~~~~
(0, - 4) are coordinates of y-intercept.
( - 1, 4)
m = [tex]\frac{4 + 4}{-1-0}[/tex] = - 8
y = - 8x - 4
