Find the missing side of the triangle :)
Answer:
x=15
Step-by-step explanation:
Hey There!
So what we want to do is inverse operations from the formula of area of a triangle
The area is equivalent to
[tex]A=\frac{hb}{2}[/tex]
h=height
b=base
now we setup an equation with what we are given
we are given A (area) and h(height)
so the equation looks like...
[tex]75=\frac{10b}{2}[/tex]
now we solve for b (x)
step 1 multiply each side by 2
75x2=150
/2x2 cancels out
now we have
150=10b
step 2 divide each side by 10
150/10=15
10/10 cancels out
b=15
We can conclude that the base (aka x) is equal to 15
Mr. Hampton asked his students to solve the equation 4x2−5x=9 by using the quadratic formula. Which student set up the formula correctly? Drew Valerie Mishka x=5±−(5)2−4(4)(9)√2(4) x=5±−(5)2−4(4)(−9)√2(4) x=−5±(−5)2−4(4)√−92(4) A. MIshka B. Valerie C. Drew
Answer:
x = 5 ± √(-5)² - (4)(4)(-9) / 2(4)
Step-by-step explanation:
x=5±−(5)2−4(4)(9)√2(4)
x=5±−(5)2−4(4)(−9)√2(4)
x=−5±(−5)2−4(4)√−92(4)
x = -b ± √b² - 4ac / 2a
Given equation:
4x²- 5x = 9
4x² - 5x - 9 = 0
a = 4
b = -5
c = -9
x = -b ± √b² - 4ac / 2a
x = -(-5) ± √(-5)² - (4)(4)(-9) / 2(4)
x = 5 ± √(-5)² - (4)(4)(-9) / 2(4)
The correct formula is
x = 5 ± √(-5)² - (4)(4)(-9) / 2(4)

Answer:
14, 18, 20
Step-by-step explanation:
You have to replace the number in the "s" column with the "s" in the problem. For example the first number in the table is 2 so you have to put 2 into the problem then add it with 12 and you get 14.

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

Carrie drew a scale drawing of the auditorium. The stage is 3 inches wide in the drawing. The actual stage is 30 feet wide. What scale did Carrie use for the drawing?
Answer:
1 : 120
Step-by-step explanation:
Given that ;
Actual width = 30feets
Width in drawing = 3 inches
Recall :
1 foot = 12 inches
Actual width in inches : (30 * 12) = 360 inches
Comparing actual width to drawing width
3 inches : 360 inches
1 : 120
Scale used is :
1 : 120
What is the slope of a line that passes through the two points (12, -18) and (11,12)
Write an equation and find the value of x
x+2x+7=22
x+2x=22-7
3x=15
x=15/3=5
In this equation we take the unknowns to the first member and the integers to the second member, then when subtracting and adding we divide the number of the second member by the number of the second member.

Bags of popcorn cost $0.50 each, and bags of chips cost $0.75 each. The equation 0.50x + 0.75y = 10 represents the number of popcorn and chip bags that can be bought with $10. If no chips are bought, how many popcorn bags can be purchased? *
Answer:
20
Step-by-step explanation:
If no chips are bought, then:
0.5x + 0.75(0) = 10
0.5x = 10
x = 20
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

At a toy shop, 45 toys were sold in September. A bonus will be given to workers if they can increase sales by 40% in October. How many toys must the sales team sell in October to receive the bonus?
Answer:
First off, we can find the number that has to be increased by multiplying the original amount by 40%:
45×40%
=45×0.4
=18
We can then add the above amount to the original amount to find the toys they must sell:
45+18
=63
They must sell 63 toys to get the bonus.
Alternatively:
The total percenrage of toys need to be sold to get a bonus with the 40% increase:
=100%+40%
=140%
The amount of toys:
=45×1.4
=63
Therefore the answer is 63.

A rectangular lawn 40 m by 20 m is surrounded all around outside by a path which is 3 m wide. The area of the path is _____ sq. m
Answer:
The area of the path is 626 square meters.
Step-by-step explanation:
Area of ABCD (of the rectangle)
Given length = 40m
Given breadth = 20m
Area = Length × breadth
= 40m × 20m
= 800m^2
External path = 3m wide
Length =40m+3m+3m=46m
Breadth = 25m+3m+3m= 31m
Area of PQRS= Length × breadth
46m ×31m = 1426m^2
Area of path = Area of PQRS - Area of ABCD
= 1426m^2 - 800m^2
= 626m^2
The area of the path is 626 square meters.
